With the improvement of the textile technology, diamond cotton, what is the difference between diamond cotton fabric and pure cotton fabric? Which fabric is better? The following small series will give you a brief introduction, let's get to know it. The difference between diamond cotton fabric and pure cotton fabric: First of all, diamond cotton has a better flashing effect, which can fully make your clothes more beautiful. At the same time, for everyone, when using such fabrics, the breathability effect and good comfort effect will bring you a very good wearing experience. In the current trend of the times, this is a A very popular fabric. What is the difference between diamond cotton fabric and cotton fabric? Which kind of fabric is better? Pure cotton fabrics have always been a kind of fabric that everyone likes to use in their lives. There are many advantages of pure cotton. Among them, the sweat-absorbing effect is better, and it has a certain elasticity, and it is comfortable to wear. In terms of price, such fabrics are also very good. The cotton fabric is made of cotton as a raw material, and is woven by a looms, which are intertwined by the warp and weft yarns. Diamond cotton is a woven fabric. It has a glittering effect and is breathable and comfortable. It is currently a popular fashion material. It is better to wear it or cotton, and the diamond is better. Generally speaking, if you are making women's or fashion, then you can choose the diamond face, so the effect will be better. However, if you are only making pajamas, then it is recommended that you use a certain amount of pure cotton fabric, so that the effect will be much better than diamond cotton. It will also bring you very good results. Therefore, diamond cotton fabrics and pure cotton fabrics should be judged according to the actual needs of everyone, and there are more introductions to purchase knowledge. Go and find out.

According to foreign media reports, recently scientists have invented a new way to deal with the cold and dampness that skiers face when they fall on a ski slope. That is a new type of jacket material that is lighter, softer and more comfortable. A small company called Voormi in Colorado, USA, is selling a technology that uses a single layer of material to create a waterproof, breathable material. It may have been a major development in outdoor apparel since the first GORE-TEX jacket with a waterproof breathable membrane in the 1970s. Voormi's new jacket Voormi released this latest technology at the Snow Sports Industry Association Product Show last month and it is said to replace the hard and bulky windbreaker and to support multiple custom features - waterproof, isolated or windproof - - The traditional hierarchical system of clothing, while ensuring light and thin. The release of this technology has caused great uproar in the US $1.5 billion annual outdoor apparel market. "Our point of view is to transform the waterproof and breathable technology into a single-layer construction line process," says Timmy Smith, marketing director. "So this is the equivalent of another 1978 revolution. We pressed the restart button." Let us first review history: In 1969, William Gore and Bob Gore invented GORE-TEX using polytetrafluoroethylene (PTFE, the basic material of PTFE). When rapidly stretched into a thin film, PTFE can become a thin film with pores smaller than liquid droplets but larger than evaporated water molecules. Therefore, liquid water, such as rain or snow, cannot penetrate this layer of material, but human body moisture, such as sweating, can penetrate. GORE-TEX is not the only film of its kind on the market. When the patent expired in 1997, a series of clothing companies proposed alternative versions. Waterproof or windproof membranes are just one of the cores of many outdoor apparel, and Voormi's latest technology will still use them. The only difference is the use of thin films. Unlike traditional waterproof-breathable fabrics, which require two layers of material, Voormi's latest technology is a single layer fabric with a film core that is lighter, more flexible and more versatile. The film itself is very fragile, so the textile company will laminate the film to the outer fabric to create a two-layer (2L) fabric that is then cut and sewn into a jacket or trousers or a sleeping bag. Most of the time, an additional layer of padding is needed to improve durability. This padding is generally a polyester warp knitted fabric, that is, a material used for a woman's bra. These constitute the functional part of the clothing, but the overall clothing is very bulky due to the fabric layer, laminating adhesive, and waterproof tape needed to cover the line hole. And these layers can affect the breathability of the membrane, thereby reducing its efficacy. Voormi's latest technology is completely lax. [We are not going to glue the film to the woven fabric. Instead, we put the film in the weaving machine and weave it on the film, so we obtained a single layer of fabric that produced the (membrane) core of this process. Smith explained. "This is a completely new platform." Voormi can "adjust" the characteristics of the film - the balance between waterproof and breathable You may ask, weave millions of pinholes in the film, do not turn the film into a filter? And this is the mystery of Voormi's refusal to disclose details. Smith said the company has found a way how to reconstruct the integrity of the film after the weaving process. Smith also said that Voormi can "adjust" the characteristics of the film - the balance between waterproof and breathable, which is the function of the size of the hole in the film. If they are designing fabrics that target cold but dry conditions, such as Colorado, where Voormi is located, "we might assure that the film maintains 70% water repellency," Smith said. "Adjusting the waterproof and breathable balance is part of the project." The clothes they designed should be dry and more breathable and comfortable than traditional waterproof clothing. The waterproof and breathable key has always been waterproof, which is why many jackets still have zippered vents. In fact, because of the really waterproof (Gore-led) standard is so high that Voormi does not claim that his clothes are 100% waterproof. However, the company said that as long as it is not a storm flood, the clothes they design should be able to ensure that it is dry and more breathable and comfortable than traditional waterproof clothing. Smith said that Voormi's technology is suitable for any type of membrane, not only waterproof-breathable, but also suitable for almost any type of yarn or yarn blend. Voormi's own material is a wool blend. "So you can get a basic layer of wind-resistant underwear," explains Smith. [This is a brand new product category. We can create a single layer of intermediate protection-for example, a windbreaker T-shirt that can be worn on the run, without getting wet due to sweating." Voormi's first product, Drift Hydro, is a hybrid type of soft shell. It is unusually lightweight as a coat, and it looks more like an insulating middle layer - soft looped wool inside and hard-pulled outside. For anyone accustomed to traditional lamination and ancient multi-layer technology, this design is truly jaw-dropping. Although it sounds very cool, but as the effectiveness of this clothing is really like publicity, there are still many problems. Voormi, a small brand in the town of Pagosa Springs, Colorado, is not yet known for skiing and climbing communities outside the town. Drift Hydro is just one of three pieces of clothing that Voormi has produced using their unique core construction technology. Although more products will be launched in succession, the price of this item of clothing is already as high as $400. All of Voormi's clothing is made in the U.S., up to the only U.S.-owned material, down to sheep that produce wool. This is great, but even with flexible domestic processing, you may not find a lot of such clothing on the store shelves. However, Voormi's goal is not to become a giant clothing brand. Smith said that the goal has always been to license other core building technologies to other companies, just as WL Gore owns Core-Tex's permission. From the very beginning, Voormi was actually two companies: a clothing manufacturer and a research and development department called SWNR (starting with the new rules). Smith pointed out that both aspects are indispensable because the situation is different from that in 1969. The licensing may not be as simple as Gore at the time. "Any big (clothing) company has no incentive to do this, because they can sell a basic layer and a middle layer, and a series of things." Voormi's retail products actually act as a "catalyst." SWNR produces innovative products, and Voormi proves that this concept is feasible at the technical and commercial levels. At present, the company has not signed any major license agreement, nor has it declared any partner at the snow sports industry association product exhibition. The current core construction technology is only reflected in Voormi's own clothing, which is currently feasible because they have bigger plans. Although the company currently has only a few employees, the employees are a group of textile engineers, chemists, and other innovators. The founder, Dan English, was the general manager of Microsoft Business Solutions; Doug Lumb, the executive vice president of development, worked for Polartec, a global leader in fleece fabrics, for 43 years. He participated. A number of innovative inventions, including artificial hair; Ingris's son Dustin spent several years as a mountaineering guide in the harsh conditions of the Alaskan wilderness, with many years of actual combat experience. Even the marketing director Smith worked as a chemical engineer at WL Gore for 12 years before joining Voormi. [This is just the tip of the iceberg that Voormi is currently developing. You will see new things in the next few years. Under the greater context of the future, you will understand what Voormi is doing."

The effect of disperse dye dyeing on the heat transfer of disperse dyes is not the redistribution of dyes in the two phases of fiber and surface solvent, but its inherent physical characteristics, which also results in the decrease of color fastness and color variation in dry heat treatment of polyester fabrics after dyeing. Key factors: by analyzing the dyeing temperature, heat treatment temperature and time, the influence of dye sublimation, surfactant and finishing agent, dyeing method and heat setting on the heat transfer of dyes, the pre dyeing high temperature pre-determined, non-contact hot air drying and low temperature soft drying process under 130 ℃ and low temperature slow resin finishing process are adopted as much as possible, The effect of heat transfer of dyes is controlled to a minimum. Polyester fabrics (pure polyester fabrics or polyester cotton, polyester viscose and other interwoven and blended fabrics) are dyed with disperse dyes (especially the deep color is dyed by high temperature and high pressure method), and after dry heat treatment at 130 ℃, such as after dyeing, such as heat drawing setting and resin baking, there are usually different changes in the following three aspects, such as the dyeing fastness (soap washing, friction, sun exposure) is obviously reduced, Generally, the medium dark color decreased by 0.5-1.5; The color light of cloth surface changed to different degrees; The pollution of the cotton adhesive components will increase significantly in the interweaved or blended fabrics such as polyester and cotton. 2. The thermal transfer of disperse dyeing polyester fiber dyed with disperse dyes, during the dry heat treatment, the color fastness and color light variation are decreased. It is the thermal mobility of disperse dyes. The so-called heat transfer refers to the phenomenon that some dyes migrate from the inside of the fiber to the surface of the fiber during the dry heat treatment process above 130 ℃ after dyeing with disperse dyes. It is generally believed that the thermal mobility of disperse dyes is the distribution phenomenon of dyes in the two phases of fibers and solvents attached to the surface of fibers (surfactants, softeners, resins, antifouling agents, antistatic agents, etc.) which dissolve disperse dyes. It is believed that if there is no second phase solvent on the surface of fiber, the thermal migration will not occur. In fact, this interpretation is not in line with the reality. If pure polyester fabric is dyed at high temperature and high pressure, it is not treated after any post treatment, washed with hot water and cold water and dried. It is directly dried and heat treated at 180 ℃ for 35S, and the heat transfer phenomenon is still very obvious. Thermal mobility is a kind of physical property inherent in disperse dyes. It is not a phenomenon of attachment caused by the existence of the second phase solvent. The thermal transfer process of disperse dyes can be explained as follows: ① during the high temperature dyeing, the structure of polyester fiber becomes loose, and the disperse dyes diffuse from the surface of the fiber into the fiber, and mainly act on the polyester fiber by hydrogen bond, dipole gravity and van der Waals force. ② When the dyed fiber is treated at high temperature, the vibration of the molecular chain is intensified due to the higher activity energy of the long chain given by the heat energy, and the microstructure of the fiber is relaxed again, which leads to the weakening of the binding force between some dye molecules and the polyester long chain. Therefore, some dye molecules with high activity energy and higher degree of self-reliance migrate from the inside of the fiber to the surface of the fiber with relatively loose structure, and combine with the fiber surface to form surface dyes or adhere to the adjacent cotton adhesive components. ③ During wet fastness test. The dye which is not strong enough and the dye adhering to the cotton adhesive component can easily get rid of the fiber and enter the solution, polluting the white cloth; Or directly adhere to the test cloth by friction, thus showing the wet fastness and friction fastness of the dye decreased. Why is the fastness of disperse dyeing poor? Disperse dyeing is mainly high temperature and high pressure when dyeing polyester fiber. Although the disperse dye molecules are small, it can not guarantee that all dye molecules enter the fiber during dyeing, some disperse dyes will adhere to the surface of the fiber, resulting in poor fastness. The reduction cleaning is used to improve the fastness and color light of the dye molecules that have not entered the fiber. Polyester fabric is dyed with disperse dyes, especially in medium and dark colors. In order to remove the floating color and the oligomer remaining on the surface of the fabric, and improve the dyeing fastness, it is usually necessary to carry out reduction cleaning after dyeing. Blended fabric generally refers to yarn made of two or more components, so this kind of fabric has the advantages of these two components. And by adjusting the proportion of components, we can obtain more characteristics of one of the components. And blending generally refers to the short fiber blend, that is, the two kinds of fibers with different components are mixed together in the form of short fiber. For example: polyester cotton blended fabric, also known as t/c, cvc.t/r, etc. It is made of polyester staple fiber and cotton fiber or man-made fiber. It has the advantages of: it has the appearance and hand feel of the whole cotton cloth, reduces the luster of polyester fabric and the hand feeling of chemical fiber, and improves the level. The color fastness of polyester fabric is improved. Because polyester cloth is color fastness at high temperature and the color fastness is higher than that of all cotton, the color fastness of polyester cotton blended fabric is also improved compared with that of all cotton. However, to improve the color fastness of polyester cotton, it is necessary to do reduction cleaning (called r/c), and after dispersion after high temperature dyeing. Only after the reduction and cleaning can the ideal color fastness be achieved. The short fiber blending makes the characteristics of each component play evenly. Similarly, other components blending can also play their own advantages to meet some functional or comfort or economic requirements. However, in the high temperature dispersion dyeing, due to the mixing of cotton or human cotton fiber, the dyeing temperature cannot be higher than that of polyester cloth. However, the strength or tear strength of polyester cotton or polyester cotton artificial fiber cloth will decrease sharply under the stimulation of strong alkali or insurance powder, and it is difficult to achieve the quality of products in the following links. The relationship between dyeing mode and heat transfer is that when the dry heat treatment is over 130 ℃, the heat transfer phenomenon is common in the fabric dyed with disperse dyes. But the heat transfer direction of dye is different with different dyeing methods. ① The atmospheric boiling dyeing is light color ring dyeing, and there is little sign of heat transfer from the inside and outside after high temperature dry heat treatment. The dye on the surface of the fiber is like the internal migration or diffusion of the fiber due to the concentration gradient. ② The distribution of dye in the fiber is also a certain degree of concentration gradient. During the high temperature heat treatment, some dye molecules migrate to the inside, and some dye molecules move from the inside of the fiber to the surface of the fiber or into the second phase solvent on the surface of the fiber. ③ The dye has good dye permeability and no gradient in the fiber. So when the heat treatment is high temperature, the dye only moves outward in one direction, which has a great influence on the color light and fastness of dyed fabric, especially dark color. The relationship between heat setting and heat transfer, the heat transfer of dye is the same in the process of high temperature dry heat treatment. The pre dyeing setting has a certain inhibition effect on the heat transfer of the dye in dry heat treatment, but the inhibition effect has a direct relationship with the light color of the fixed blank by 10% ~ 15% (the lighter the color, the less the heat transfer of the dye). Therefore, the effect of the predetermined type on the heat transfer of dyes is not significant. The countermeasures are as follows: 1. The thermal mobility of disperse dyes with different structures is different, so the dyes with lower thermal mobility should be selected when dyeing dark colors. 2. Because the color depth has a significant effect on the thermal mobility of dyes, it is necessary to avoid reaching or exceeding the saturation value of dyeing. When choosing dyes, we should consider not only the size of the heat transfer of the dye itself, but also the strength of its promotion and compatibility and additivity. 3. Because surfactants have obvious promotion effect on the thermal mobility of dyes, the principle of "can not use, less use, and not use when not, should be carefully selected" principle. 4. The dye attached to the surface of the fiber (floating color) will aggravate the influence of the heat transfer on the color fastness of the dyed fabric. Therefore, after dyeing (especially dark color), the reducing agent (reducing agent terlipine) should be used for reducing cleaning to remove floating color completely. 5. Because the commonly used softeners have a serious impact on the thermal mobility of dyes, the softener must be carefully selected when finishing the dyed dyed fabrics (for the softener used for polyester fabrics, the influences on the softness, smoothness, yellowing and the thermal mobility of dyes must be considered at the same time). 6. After finishing the dyed fabric, a layer of resin film is formed on the surface of the fiber, which weakens the influence of the heat transfer of the dye on the color fastness of the dyed fabric. However, the influence on the color light of the dyed fabric is often obvious. In addition to the thermal mobility of dyes, the effect of the effects on some dyes sensitive to metal ions and metal ions from metal salt catalysts in resin layer is also directly related. 7. The heat transfer of disperse dyes and the influence of related factors on the heat transfer are obvious only after dry heat treatment at 130 ℃. That is, heat treatment temperature is the main factor of thermal transfer of disperse dyes. 6. The factors considered in post finishing 1. Try to use pre dyeing high temperature pre dyeing pre-determined type, so that the post dyeing setting tension can be used with mild conditions, but attention should be paid to the light color and the deep edge problem is easy to occur. 2. Try to dry with no contact hot air below 130 ℃, such as the cross guide roller dryer. And avoid drying by contact drying. 3. The low temperature soft drying and drawing process below 130 ℃ is used as far as possible, and the high temperature drying and drawing process is avoided. Fourth, low temperature and slow resin finishing process shall be adopted as far as possible, and high temperature and fast resin finishing process shall be avoided. Other effects are different in the heat transfer tendency of different disperse dyes. The heat transfer of different dyes is different under the same dry heat condition, so the color and light of the dye are changed. 1. The relationship between the dyeing depth and the heat transfer of the fibers is proportional to the heat transfer of disperse dyes. That is, the darker the color is, the greater the heat transfer of the dyes is, the more serious the influence on the quality of the dye is. 2. The relationship between heat treatment temperature and heat transfer is usually the higher the temperature of dry heat treatment after dyeing, the greater the heat transfer of dye, the more serious the influence on the color light and dyeing fastness of dye. The heat transfer of dyes is not large when the heat treatment is below 130 ℃,; The heat transfer of dyes is obviously intensified when the heat treatment is over 130 ℃. 3. The relationship between heat treatment time and heat transfer is within 20-40s, and the migration of dyes increases rapidly with the time; In the range of 40-50s, the increase of the heat transfer of dyes was not obvious; The heat transfer of disperse dyes with low temperature and medium temperature decreased over 50s. Obviously, this is related to the increase of sublimation of dyes. 4. The relationship between the heat sublimation and the heat transfer of dyes is the relationship between some high temperature dyes with good sublimation resistance, some of which have small thermal mobility (such as disperse grey s-bn), while others have great heat transfer (such as disperse red s-3gfl, disperse deep blue HGL, etc.). Some low temperature and medium temperature dyes with poor sublimation resistance (such as disperse red B, Fulong brilliant red e-rln, etc.) have a small thermal mobility, which is closely related to the sublimation of dyes. Therefore, there is no obvious rule between the sublimation and the heat transfer of dyes.

As the summer approaches, the hot weather gradually becomes one of the issues that outdoor sports enthusiasts pay attention to. Therefore, wearing a comfortable outdoor sportswear becomes one of the important factors affecting the mood of outdoor sportsmen.

Since the beginning of summer, many regions in China have been hit by continuous torrential rains. Due to considering the safety of travel, they also have to temporarily interrupt some of the more risky walking and crossing activities. When outdoor activities are suspended, outdoor shoes often have to be put on the shelf. In this hot and humid weather, the maintenance and storage of outdoor equipment has become a headache for many people. Outdoor shoes made of Gore-Tisse-lined fabrics have long-lasting waterproof and highly breathable features derived from a thin, durable Goreth film in the liner fabric. Therefore, in the maintenance of this type of outdoor shoes using Goretex Lining fabric, only need to be careful not to pierce or wear the inner film, the durable waterproof and high air permeability of the shoes will not be affected. Every time you return from your trip or when you are not wearing outdoor shoes for a long time, you need to do some basic maintenance and preparation. First, use a soft brush dipped in water to brush the dirt on the shoe, pour out the sand stone in the shoe; then remove the insoles to relax the laces, let the shoes dry naturally in the shade, if the shoes into the water or have been damp, you can Plug in newspapers or tissues to absorb moisture. With the outdoor shoes made of Gore's lining fabric, although the water-repellent treatment has been done before leaving the factory, the water-dumping function will gradually lose its function during use. When it is found that the water can no longer turn into water droplets on the upper, it is necessary to dial water on the surface of the shoe, including tongue tongues, etc. In addition, special attention must be paid to the cleanliness marked by the outdoor shoe manufacturer in the product description. And maintenance methods.

In daily life, disposable rags are more and more popular. From traditional rags to disposable rags, people have changed their new perception of kitchen cleaning. We should not only understand the characteristics of each material, but also pay attention to whether different materials are consistent with your needs. Now, fiber composite materials have different advantages. Let's take a look. New low temperature thermal insulation technology should be deeply studied (including the process of thermal insulation structure materials, etc., and applied to the thermal shield support and other components of the radiant cooler, to develop a highly efficient radiant cooler that can greatly improve the refrigeration performance compared with the traditional radiant cooler when the volume weight is the same or the increase is small). These problems include mechanical properties and reliability of new materials and process structures, pollution control, coupled ground assembly and testing of heat pipes, etc. At present, the pollution control technology of radiant cooler during ground storage, transportation and on orbit operation needs to be improved and developed to further improve its working life. In addition, the matching and coupling technology between the radiant cooler and the infrared detector of multi band, multi-channel and large area array, heat pipe technology, as the high efficiency thermo mechanical coupling technology involved in the pre stage refrigeration of other refrigeration methods, also needs to be further studied and developed to broaden the application field of space radiant refrigeration technology. Due to the advantages of fiber materials such as high strength, light weight, corrosion resistance, fatigue resistance and convenient construction, the use of fiber reinforced polymer (FRP) for structural strengthening has attracted increasing attention. The experimental results of beams strengthened with fiber show that the bearing capacity and stiffness of beams strengthened with externally bonded fiber are significantly improved, but the section ductility is significantly reduced. In the aspect of cantilever plate reinforcement, the feasibility and anchorage method of fiber reinforced cantilever plate are discussed, and the bearing capacity of the strengthened cantilever plate with additional anchorage on the plate is studied.

Nonwovens are popular nowadays. Many people do not know how to identify non-woven fabrics when they buy them. In fact, according to the different chemical composition of non-woven fibers, the combustion characteristics are also different, so as to roughly distinguish the major categories of aluminized non-woven fibers. The comparison of combustion characteristics of several common non-woven fibers is introduced as follows. 1. Polypropylene fiber: close to the flame: melting shrinkage; Contact with flame: melting, burning; Leave the flame: continue to burn; Smell: paraffin smell; Residue characteristics: gray white hard transparent bead. 2. Cotton, linen, viscose fiber, copper ammonia fiber: close to the flame: non shrinking and non melting; Contact with flame: rapid combustion; Leave the flame: continue to burn; Smell: smell of burning paper; Residue characteristics: a small amount of gray black or gray white ash. 3. Spandex fiber: close to the flame: melting shrinkage; Contact with flame: melting, burning; Leave the flame: self extinguishing; Smell: special smell; Residue characteristics: white colloidal. 4. Silk and wool fiber: close to the flame: curl and melt; Contact with flame: curl, melt, burn; Leave the flame: slow burning and sometimes self extinguishing; Smell: smell of singeing hair; Residue characteristics: loose and brittle black particles or coke. 5. Polyester fiber: close to flame: melting shrinkage; Contact with flame: melting, smoking, slow burning; Leave the flame: continue to burn, sometimes self extinguish; Smell: special aromatic sweet taste; Residue feature: hard black ball. 6. Vinylon fiber: close to the flame: melting shrinkage; Contact with flame: melting, burning; Leave the flame: continue to burn and emit black smoke; Smell: special fragrance; Residue characteristics: irregular brown hard lump. 7.

Acrylic fiber: close to the flame: melting shrinkage; Contact with flame: melting and smoking; Leave the flame: continue to burn and emit black smoke; Smell: spicy; Residue characteristics: black irregular beads, fragile. 9. Chlorine fiber: close to the flame: melting shrinkage; Contact with flame: melting, burning, emitting black smoke; Leave the flame: self extinguish; Smell: pungent smell; Residue characteristics: dark brown hard lump. The non-woven fabric has no warp and weft threads. It is very convenient to cut and sew, and it is light in weight and easy to shape. It is very popular with handicraft lovers. Because it is a kind of fabric formed without spinning and weaving, it is simply formed by directional or random arrangement of textile short fibers or filaments to form a fiber mesh structure, and then reinforced by mechanical, thermal adhesive or chemical methods. It is not interwoven and knotted by yarns, but the fibers are directly bonded together by physical methods. Therefore, when you get the scale in your clothes, you will find that there is no thread end. Nonwovens break through the traditional textile principle, and have the characteristics of short technological process, fast production rate, high output, low cost, wide use, and multiple sources of raw materials. Relationship between non-woven fabric and spunbonded fabric Spunbonded fabric and non-woven fabric are subordinate. There are many production processes for the manufacture of non-woven fabrics, of which the spunbonded method is one of them Spunbonded non-woven fabric (including spunbonded method, melt blown method, hot rolling method, spunlace method, and most nonwoven fabrics produced by spunbonded method on the market) According to the composition, non-woven fabrics include polyester, polypropylene, nylon, spandex, acrylic, etc; Different ingredients will have different nonwoven styles. Spunbonded fabric, usually refers to polyester spunbonded, polypropylene spunbonded; The styles of these two kinds of cloth are very similar, which can be identified by high temperature test. Non woven fabric is a kind of non-woven fabric. It is a non-woven fabric formed by directly using polymer chips, short fibers or filaments to form fibers through air flow or mechanical mesh, then through spunlace, needle punching, or hot rolling reinforcement, and finally after finishing. A new type of fiber product with soft, breathable and flat structure, which has the advantage of not producing fiber chips, being strong, durable and silky soft, is also a kind of reinforcement material, and also has a cotton feel. Compared with cotton fabrics, non-woven bags are easy to form and cheap. advantage: 1. Light weight: Polypropylene resin is the main raw material for production, with a proportion of only 0.9, which is only three fifths of cotton. It is fluffy and feels good. 2. Soft: It is composed of fine fibers (2-3D) and formed by light spot hot melt bonding. The finished product has moderate softness and comfort. 3. Water pumping and air permeability: Polypropylene chips do not absorb water, with zero moisture content. The finished product has good water pumping performance. It is composed of 100% fibers with good porosity and air permeability, which can easily keep the cloth dry and clean. Polypropylene Non-woven 4. Non toxic and non irritating: The product is made of FDA food grade raw materials, free of other chemical ingredients, stable in performance, non-toxic, non odor, and non irritating to the skin. 5. Antibacterial and chemical resistant agents: Polypropylene is a chemically passive substance, which is not moth eaten, and can isolate the corrosion of bacteria and insects in the liquid; Antibacterial, alkali corrosion, and finished products will not affect the strength due to corrosion. 6. Antibacterial property. The product has water extraction property, does not mold, and can isolate the corrosion of bacteria and insects in the liquid, and does not mold. 7. Good physical property. It is made of polypropylene spinning directly laid into a mesh and thermally bonded. The strength of the product is better than that of ordinary staple fiber products. The strength has no directivity, and the longitudinal and transverse strengths are similar. 8. In terms of environmental protection, the raw material of most non-woven fabrics is polypropylene, while the raw material of plastic bags is polyethylene. Although the names of the two substances are similar, their chemical structures are quite different. The chemical molecular structure of polyethylene is quite stable, and it is extremely difficult to degrade, so it takes 300 years for the plastic bag to be completely decomposed; The chemical structure of polypropylene is not firm, and the molecular chain can be easily broken, which can be effectively degraded. In addition, polypropylene enters the next environmental cycle in a non-toxic form. A non-woven shopping bag can be completely decomposed within 90 days. Moreover, non-woven shopping bags can be reused for more than 10 times, and the environmental pollution degree after being discarded is only 10% of that of plastic bags. Disadvantages: 1) It has poor strength and durability compared with textile cloth. 2) It cannot be washed like other fabrics. 3) The fibers are arranged in a certain direction, so they are easy to split from a right angle, etc. Therefore, the improvement of production methods is mainly focused on the improvement of prevention of splitting.

Non woven fabric is a new kind of material with low price but no pollution. It is loved by handicraft lovers because of its unique advantages. Today, let's introduce the application of non-woven fabrics in various industries, and what they can be used for. 1. First, let's talk about the use of non-woven fabric in the industrial field: it is used as the base material of roofing waterproof roll and asphalt tile, aluminized non-woven fabric reinforcement material, polishing material, filtering material, insulating material, cement packaging bag, geotextile, wrapping cloth, etc; 2. Non woven fabrics for home decoration: wall covering, table cloth, bedspread, bedspread, etc; 3. Nonwovens for agriculture: crop protection cloth, seedling raising cloth, irrigation cloth, thermal insulation curtain, etc; 4. Medical and sanitary non-woven fabrics: surgical clothes, protective clothing, disinfection wrap, masks, diapers, civilian dusters, wiping cloths, wet face towels, magic towels, soft towel rolls, beauty products, sanitary napkins, sanitary pads, and sanitary cloths; 5. Non woven fabrics are also used in other industries, such as space cotton, thermal insulation and sound insulation materials, asphalt felt, smoke filter tips, tea bags, shoes, etc Coated non-woven fabric, which is a new type of fabric. The difference between this and laser non-woven fabric is one is composite, the other is embossing. The coated non-woven fabric weighs dozens of grams more than the composite non-woven fabric, and is thicker! The coated non-woven fabric is more tactile than the composite non-woven fabric, and its texture is more realistic than the laser composite non-woven fabric. There are dozens of patterns of coated embossed non-woven fabrics in the market, such as checker pattern/bark pattern/small hole pattern/pinhole pattern/rice pattern/mouse pattern/brushed pattern/crocodile pattern/strip pattern/mouth pattern/dot pattern/cross pattern, etc. Cladding embossed square pattern (5 sheets) The products are suitable for packaging, decoration and other industries, and are widely used in handbags, shoe bags, storage products, wine boxes, tea boxes, gift packaging boxes, jewelry boxes and other products. The products are colorful, bright and fashionable! It is a perfect substitute for traditional PU products, with better performance ratio!

Introduction to various common properties of PP non-woven fabric (1) Physical properties: PP non-woven fabric is non-toxic and tasteless milky white high crystalline polymer, which is one of the lighter varieties of all plastics at present. It is particularly stable to water, and its water absorption rate is 14h in water Only 0.01%. The molecular weight is between 80000 and 150000, with good formability. However, due to the large shrinkage, the original wall products are easy to sag, and the surface of the products is shiny and easy to color. (2) Mechanical properties: PP non-woven fabric has high crystallinity and regular structure, so it has excellent mechanical properties. Its strength, hardness and elasticity are higher than that of high-density PE (HDPE). The outstanding feature is bending fatigue resistance (7 × 10 ^ 7) The secondary opening and closing are bent without damage, and the dry friction coefficient is similar to nylon, but it is inferior to nylon under oil lubrication. (3) Thermal performance: PP non-woven fabric has good heat resistance, melting point is 164~170 ℃, and products can be sterilized at a temperature above 100 ℃. Under the action of no external force, it will not deform at 150 ℃. The embrittlement temperature is - 35 ℃, which will occur below - 35 ℃, and the heat resistance is not as good as PE. (4) Chemical stability: PP non-woven fabric has good chemical stability. It is relatively stable to other chemical reagents except for being eroded by acid, but low molecular weight aliphatic hydrocarbons, aromatic hydrocarbons, etc It can soften and swell PP non-woven fabric, and the chemical stability will be improved with the increase of crystallinity. Therefore, PP non-woven fabric is suitable for making Russian and Chinese chemical pipes and accessories, with good anti-corrosion effect. (5) Electrical performance: The high frequency insulation performance of non-woven fabric is excellent. Because it hardly absorbs water, the insulation performance is not affected by humidity, and has a high dielectric coefficient, It can be used to make heated electrical insulation products, and the breakdown voltage is also very high. It is suitable for electrical accessories, etc. Good voltage resistance and arc resistance, but high static electricity, easy to aging when contacting with copper. (6) Weathering resistance: non-woven fabrics are very sensitive to ultraviolet light, and the aging resistance can be improved by adding zinc oxide thiopropionic acid lauryl ester, carbon black like milky white filler, etc.

1. Woven: Woven fabric can also be called "tatting", which is the process of forming woven fabric with yarn as warp and weft. It is an important part of textile industry production. According to the types of raw materials used, it can be divided into cotton, wool, silk and hemp fabrics, and its products are collectively referred to as woven fabrics. The varieties and uses of woven fabrics are extremely wide, and suitable yarn materials and appropriate fabric structures are selected according to different use requirements. 2. Knitting: Knitting is a technological process in which various raw materials and varieties of yarns are formed into loops by knitting needles, and then connected into knitted fabrics through string sleeves. The knitted material is soft, has good wrinkle resistance and permeability, and has greater extensibility and elasticity. It is comfortable to wear. 3. Non woven fabric manufacturing: Non woven fabric system refers to the manufacture of products similar to cloth made of chemical fiber as the basic raw material and chemically bonded. It is also called nonwovens because it is not used for weaving. It directly uses polymer chips, short fibers or filaments to form a mesh through air flow or machinery, and then through water pricking, acupuncture, or hot rolling reinforcement, and finally through post finishing to form a non-woven fabric.

Taffeta is mainly used as lining. Taffeta includes silk taffeta and spun taffeta. Taffeta has the meaning of plain fabric. It is also called taffeta silk, which is a kind of mature high-grade silk fabric made of plain weave. Silk like taffeta, including polyester taffeta and nylon taffeta, also adopts the same weaving method, but the raw materials used are different, and the subsequent processing is also different. However, the processing technology of modern industry has made the level of imitation quite high, almost reaching the level of "fake", which is difficult to distinguish from the appearance and feel, only when it is used.

Cotton FIBER MATURITY can be used AS a comprehensive index to evaluate the intrinsic quality of cotton fiber, which directly affects the color, strength, fineness, natural bending, elasticity, moisture absorption, dyeing and other properties of cotton fiber. Therefore, other physical properties of cotton fiber can be estimated or measured according to the maturity of cotton fiber. The mature cotton fiber has many natural twists, good elasticity, good color and lustre. It is not suitable to form cotton knots and wires in the spinning process. The fiber has good adhesion and spinnability, uniform yarn drying, few defects, and high yarn strength. When the fiber maturity is too poor, the fiber strength is low, the fineness is fine, the elasticity and toughness are poor, and the kink is easy to form in the spinning process, so that the fiber appearance is defective and the cotton knot impurities are also added. However, the over-mature cotton fiber is thicker, and the number of fiber roots in the yarn forming section is relatively reduced, which also affects the yarn forming strength. Maturity of cotton fiber The maturity of cotton fiber refers to the degree of cell wall thickness in cotton fiber, that is, the degree of growth and maturity of cotton fiber. Many properties OF COTTON fiber are related to structure, which is restricted BY maturity TO a large extent, SO COTTON fiber maturity has a significant effect on many properties. The maturity of cotton fiber is often expressed by the maturity coefficient. The greater the maturity coefficient, the more mature the cotton fiber is. The maturity coefficient of cotton fiber is in the range of 12 ~25, the average maturity coefficient of general fine cashmere cotton is 1.5~ 20, the maturity coefficient of long cashmere cotton is more than 20. Cotton fiber maturity is generally determined according to the ratio of fiber cell wall to fiber lumen diameter. It is a comprehensive index reflecting cotton fiber strength, fineness, natural bending, water content and light. Elasticity has a great influence on the breaking strength of the processing technology and the maturity of the yarn M, the cvfA details, the coarse knotting, and the knotting 1 of the cotton. Fiber maturity corresponding mature conditions as follows: 8 immature maturity coefficient 0 8 ~ 9 normal mature (lower) 9 ~ 10 mature good maturity coefficient 0 very mature general conditions, the fibers grow mature, cell wall thickness and sectional area is large, low fiber number, high intensity, content of cellulose, turning curve, the luster bright, dyeing performance is good, the spinning performance. When raw cotton with poor maturity (maturity coefficient below 1 00) is used, it is easy to damage fibers and form cotton knots in the process of spinning, the yarn strength is low, the strip is poor, and the impurities are difficult to remove. When dyed with dark fabric, white stars will appear on the fabric surface. However, over mature cotton fiber has less bending and poor holding force, which affects yarn quality. Therefore, the maturity of cotton fiber is an important property of raw cotton, and is one of the basis for evaluating the grade of raw cotton. Relationship between Maturity and Spinning Technology Impurities and defects in raw cotton affect both spinning technology and yarn quality. The original cotton with different maturity has a great impact on the cleaning efficiency and the amount of impurities in the spinning process.

Viscose: translated as Viscose, is a kind of fabric spun from Viscose fiber, also called rayon fabric, referring to rayon, the scientific name Viscose fiber, belongs to man-made fiber, feel similar to cotton, cheaper than cotton. Viscose fabric, is a kind of sports and environmental protection fabric, because of its special nanothreaded molecular structure, like the air flow pipe on the surface of the fabric, to ensure sufficient oxygen circulation, lock moisture, so it has quite good humidity control effect. This fabric has super anti-static properties, does not produce the feeling of attachment to the body, so it is very smooth, especially suitable for sports wear. Its moisture content is most in line with the physiological requirements of human skin, with good air permeability and moisture-regulating function, and is consistently called "breathable fabric" by media at home and abroad. Its fabric has the advantages of soft feel, smooth and cool, breathable, antistatic and gorgeous dyeing.

1. High strength. The strength of short fiber is 2.6 ~ 5.7CN /dtex, and that of high strength fiber is 5.6 ~ 8.0CN /dtex. The strength in wet state is basically the same as that in dry state. Impact strength is 4 times higher than nylon, 20 times higher than viscose fiber. 2. Good elasticity. Elasticity is similar to wool, and when extended by 5% to 6%, it can recover completely. Crease resistance is far more than other types of fiber, that is, the fabric does not crease, scale stability is good. Elastic modulus, 2 ~ 3 times higher than nylon. It has good elasticity and is perfect for women's wear. In recent years, the popular stretch women's leggings can also be used for shoes and hats, home textiles, toys, crafts and so on. 3, good heat resistance, high temperature will not deformation. Good light resistance. Light resistance is second only to acrylic fiber. External lubrication, internal molecules placed tightly, the lack of hydrophilic structure between molecules, so the moisture return rate is very small, poor hygroscopic function. 4, corrosion resistance. Resistant to bleach, oxidants, hydrocarbons, ketones, petroleum commodities and inorganic acids. Resistant to dilute alkali, not afraid of mildew, but hot alkali can make its differentiation. 5, good wear resistance. Wear resistance is second only to the best wear resistance of nylon, than other natural fibers and synthetic fibers are better

Purified fiber fabric: chemical fiber fabric is loved by people because of its high fastness, good elasticity, straightness, abrasion resistance and washability, and easy storage and collection. Purified fiber fabric is a fabric made of pure chemical fiber. Its characteristics are determined by the characteristics of its chemical fiber itself. Chemical fibers can be processed into a certain length according to different needs, and woven into silk like, cotton like, linen like, elastic wool like, medium long wool like and other fabrics according to different processes.

Oxford Spinning is a shirt fabric that feels soft and the tissue structure is flat pattern change tissue or square flat tissue. In the 1900s, in order to combat the flashy and luxurious clothes of that time, a small group of maverick students from Oxford University used combed cotton fabric for design and processing, This fabric was a two-color effect, color and quiet, good air permeability, comfortable and natural. Driven by this, the fabric became a special Oxford University school uniform, and then popular in Europe and the United States for a hundred years, known as Oxford Textile.
