Nylon is the Chinese name for the synthetic fiber nylon. The translated name is also called “nylon” and “nylon”. Its scientific name is polyamidefibre, which is polyamide fiber. It is the earliest synthetic fiber variety in the world and has been widely used due to its excellent performance and rich raw material resources.
- Performances of nylon
Strength and good wear resistance, ranking first among all fibers head. Its wear resistance is 10 times that of cotton fiber, 10 times that of dry viscose fiber, and 140 times that of wet fiber. Therefore, its durability is excellent.
Nylon fabric has excellent elasticity and elastic recovery, but it is easy to deform under small external force, so the fabric is easy to wrinkle during wearing.
Poor ventilation and air permeability, easy to generate static electricity.
The hygroscopicity of nylon fabric is better than that of synthetic fiber fabrics, so clothing made of nylon is more comfortable to wear than polyester clothing.
It has good resistance to moth and corrosion.
The heat resistance and light resistance are not good enough, and the ironing temperature should be controlled below 140℃. During wearing and use, you must pay attention to the washing and maintenance conditions to avoid damaging the fabric.
Nylon fabric is a lightweight fabric and is only listed after polypropylene and acrylic fabrics among synthetic fabrics. Therefore, it is suitable for making mountaineering clothing, winter clothing, etc.
Polyamide 6 and nylon 66
The most common nylon products on the market are nylon 6 and nylon 66.
Nylon 6: The full name is polycaprolactam fiber, which is polymerized from caprolactam.
Nylon 66: The full name is polyhexamethylene adipamide fiber, which is polymerized from adipic acid and hexamethylene diamine.
Generally speaking, nylon 66 has a better feel than nylon 6, and the comfort of nylon 66 is also better than nylon 6, but it is difficult to distinguish between nylon 6 and nylon 66 on the surface. .
The common characteristics of nylon 6 and nylon 66: poor light resistance, under long-term sunlight and ultraviolet light irradiation , the strength decreases and the color turns yellow; its heat resistance is not good enough. It turns yellow after 5 hours at 150°C, the strength and elongation decrease significantly, and the shrinkage rate increases. Nylon 6 and 66 filaments have good low temperature resistance, and their resilience does not change much when temperatures are below minus 70°C. Its DC conductivity is very low, and it is easy to generate static electricity due to friction during processing. Its conductivity increases with the increase of moisture absorption rate, and increases with the increase of humidity according to an exponential function. Nylon 6 and 66 filaments have strong resistance to microbial action, and their ability to resist microbial action in silt water or alkali is second only to chlorine fiber. In terms of chemical properties, nylon 6 and 66 filaments have alkali resistance and reducing agent resistance, but have poor acid resistance and oxidant resistance.
Nylon fiber fabrics can be divided into three categories: pure blends and interwoven fabrics
Nylon pure fabrics
Various fabrics woven with nylon filaments as raw materials, such as nylon taffeta, nylon crepe, etc. . Because it is woven with nylon filament, it has the characteristics of smooth feel, strong durability and affordable price. It also has the disadvantages that the fabric is easy to wrinkle and difficult to recover.
Taslan
Taslan is a type of nylon fabric, including jacquard taslan, honeycomb taslan, full matt taslan, etc. Usage: high-end clothing fabrics, ready-to-wear fabrics, golf clothing fabrics, high-end down jacket fabrics, highly waterproof and breathable fabrics, multi-layer composite fabrics, functional fabrics, etc.
Jacquard Taslon: The warp yarn is made of 76dtex (70D nylon filament, and the weft yarn is made of 167dtex (150D nylon air textured yarn); the fabric structure adopts a double flat jacquard structure and is interwoven on a water-jet loom . The width of the fabric is 165cm, the weight per square meter is 158g, and there are varieties of different shades of purple, grass green, light green, etc. The fabric has the advantages of not easy to fade and wrinkle, and strong color fastness.
Honeycomb Taslan: The warp of the fabric is made of 76dtex nylon FDY, the weft is made of 167dtex nylon air textured yarn, the warp and weft density is 430/10cm×200/ 10cm, interwoven on a water-jet loom with a faucet. Basically, a double-layer plain weave is used. The cloth surface forms a honeycomb grid shape. The gray cloth is first relaxed and refined, alkali reduced, dyed, and then softened and shaped. The fabric It has the characteristics of good breathability, dry feel, soft and elegant, and comfortable to wear.
Full matt Taslan: fabric warp It uses 76dtex fully matted nylon-6FDY, and the weft yarn uses 167dtex fully matted nylon air textured yarn. The most prominent advantage is that it is more comfortable to wear.Good warmth and breathability.
Nisi spinning
Nylon spinning (also known as nylon spinning) is a spun silk fabric made of nylon filament. Nylon spinning has been bleached, dyed, printed, calendered, and embossed. The fabric is smooth and dense, with a silk surface. Smooth, soft to the touch, light but strong and wear-resistant, brightly colored, easy to wash and quick-drying twill fabric
Twill fabric adopts twill weave The woven fabrics have clear diagonal textures, including brocade/cotton khaki, gabardine, Crodine, etc. Among them, brocade/cotton khaki has the characteristics of thick and tight fabric body, tough and crisp, clear grain, and wear resistance.
Nylon Oxford cloth
Nylon Oxford cloth, the warp and weft yarns are made of coarse denier (167-1100dtex nylon filament, plain weave structure, the product is woven by a water-jet loom. The gray cloth is dyed, finished and coated After layer processing, it has the advantages of soft hand feeling, strong drape, novel style, waterproof, etc., and the cloth masks the nylon silk gloss effect.
Nylon blended and interwoven fabrics
Using nylon filaments Fabrics obtained by blending or interweaving short fibers with other fibers have the characteristics of various fibers.
Nan/Jin Gabardine
Viscose/nylon gabardine has two blending ratios, one is 15% nylon, 85% viscose fiber; the other is 25% nylon, 75% viscose fiber. The warp and weft yarns are all blended yarns, which are 2/2 twill weave fabrics. The warp density of this kind of fabric is nearly twice that of the weft density, so the fabric is thick and tight, tough and durable. The surface is flat, smooth and shiny. The disadvantages are poor elasticity, easy to wrinkle, low wet strength, large shrinkage, the fabric becomes hard when washed, and easy to sag when worn.
Nian/Jinfanliting
Viscose/nylon plain weave is called nylon plain weave. It has two combinations: 15% nylon, 85% viscose fiber and 25% nylon, 75% viscose fiber. Than, the fabric is blended into two-ply threads. It adopts plain weave, the front and back sides have the same appearance, and it feels very refreshing, but it is not soft enough, and its luster is second only to gabardine.
sticky/jinserge
Non/brocade serge, also known as nylon serge, belongs to 2/2 twill weave. Its appearance is similar to gabardine, its warp density is 40% smaller than gabardine, and its weft density is similar. Because the surface of serge is flatter than that of gabardine, its grain is wider, and the interweaving points are clearly visible, but its feel is not as good as gabardine, and its strength and luster are poor.
Tacky/brocade/wool tweed
Viscose/brocade/wool tweed is a worsted tweed, mostly plain tweed, referred to as three-in-one tweed. It is blended in a ratio of 4:4:2. Since yarns with different twist directions are used as warp and weft yarns, the fabric shows patterns on the surface due to the reflection of light.
Brocade/Viscose/Stretch Grosgrain
Nam/viscose/elastic grosgrain, the warp yarn is made of spandex nylon covered yarn as raw material, and is woven on an air-jet loom. The gray fabric is relaxed, desized and treated with alkali. → Dyeing (using reactive dyes and disperse dyes) → Shaping and finishing, etc. This product has the style of viscose fiber fabric, the luster effect of nylon fabric, and the elastic function of spandex fabric; the fabric has cotton texture, comfort, and stretchability.
