Fiber:
Chemical fibers refer to fibers that are made from natural or synthetic high polymers and processed through chemical methods. They can be divided into There are two categories: man-made fibers and synthetic fibers. There are two types of man-made fibers, namely man-made cellulose fibers (such as viscose fiber, rich fiber, etc.) and man-made protein fibers (such as soybean fiber, peanut fiber, etc.). The camp of synthetic fibers is relatively large, including polyester fiber (ie polyester fiber). ), polyamide fiber (nylon 6, nylon 66, etc.), polyacrylonitrile fiber (acrylic fiber), polyvinyl formal fiber (vinylon), polypropylene fiber (polypropylene), polyvinyl chloride fiber (chloropropon), polyamide Formate fiber (spandex).
Polyester
English Name: polyester fiber; China’s product name is polyester.
Polyester fiber is also called ice silk in the clothing industry. It is currently the largest variety of synthetic fibers. It is a fiber-forming polymer made from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) through esterification or transesterification and polycondensation reaction. —Polyethylene terephthalate (PET), a fiber made by spinning and post-processing. Polyester, commonly known as “Qianliang” in China, has a wide range of uses and is widely used in the manufacture of clothing fabrics and industrial products. Polyester has excellent shaping properties. The flat, fluffy or pleated shapes produced by polyester yarn or fabric after shaping can still remain unchanged after being washed many times during use. It is loved by people because of its characteristics such as strong and durable, good elasticity, not easily deformed, corrosion-resistant, insulating, crisp, easy to wash and quick-drying.
Polyester is also called triclin, and Americans also call it “darkmode” Lun”. When it appeared on the Hong Kong market, people translated it as “Chen Liang” in Cantonese, which became a household name.
Polyamide fiber
English The name Polyamide (PA for short), commonly known as nylon, was invented by the famous American chemist Carothers and his scientific research team. Nylon is a term for polyamide fiber, which can be made into long fiber or short fiber.
Nylon is the trade name of polyamide fiber, also known as Nylon . It is the first synthetic fiber in the world. The emergence of nylon has given a new look to textiles. Its synthesis is a major breakthrough in the synthetic fiber industry and an important milestone in polymer chemistry.
acetate
English Name: acetate
fiber, cellulose acetate
fiber, also known as acetate fiber. Acetate fiber has better light resistance, but poor dyeing performance. It is generally made into short fibers and can be used as artificial hair. Acetate filament has good luster, soft and smooth feel, good drape, and strong silk feel. Suitable for making underwear, bathrobes, children’s clothing, women’s clothing and interior decoration fabrics, etc. Short fibers are used for blending with cotton, wool or other synthetic fibers. The fabric is easy to wash and dry, and is mildew- and moth-free.
Viscose fiber
Sticky Viscose fiber refers to α-cellulose extracted from cellulose raw materials such as wood and plant stalks, or artificial fiber made from cotton linters, processed into spinning solution, and then wet-spun. Viscose fiber is the full name of viscose fiber. It is divided into viscose filament and viscose staple fiber.
Viscose fiber – also called rayon and viscose filament. In recent years, new high-end varieties of viscose fiber called Tencel and bamboo fiber have appeared. Viscose fiber is a cellulose fiber produced from cotton or other natural fibers. Among the 12 major textile fibers, the moisture content of viscose fiber is most in line with the physiological requirements of human skin, and it is smooth, cool, breathable, antistatic, and�� Pure acrylic fiber has poor wearability due to its tight internal structure. Therefore, its performance is improved by adding a second and third monomer. The second monomer improves elasticity and feel, and the third monomer improves dyeability.
Uses: Mainly for civilian use, can be pure or blended, made into many kinds Wool, wool, blankets, sportswear can also be used: artificial fur, plush, bulked yarn, hose, parasol cloth, etc.
5. Vinyl (water-soluble and hygroscopic)
The biggest feature is that it has high hygroscopicity and is among the synthetic fibers. The best, known as “synthetic cotton”. The strength is worse than that of brocade and polyester, but it has good chemical stability and is not resistant to strong acid and alkali. Sunlight resistance and weather resistance are also very good, but it is resistant to dry heat but not wet heat (shrinkage) and has the worst elasticity. The fabric is easy to wrinkle, dyeing is poor, and the color is not bright.
Usage: mostly blended with cotton: muslin, poplin, corduroy, underwear, Canvas, tarpaulin, packaging materials, work clothes, etc.
6. Polypropylene (lightweight and warm)
Polypropylene fiber is the lightest among common chemical fibers of fiber. It is almost non-hygroscopic, but has good wicking ability, high strength, dimensionally stable fabrics, good abrasion resistance and elasticity, and good chemical stability. But: poor thermal stability, not resistant to sunlight, and prone to aging and brittleness.
Uses: Can be used to knit socks, mosquito nets, quilts, thermal fillers, and diapers Wet and so on. Industrially: carpets, fishing nets, canvas, hoses, medical tapes to replace cotton gauze and make sanitary products.
7. Spandex (elastic fiber)
The best elasticity, the worst strength, and poor moisture absorption , has good light resistance, acid resistance, alkali resistance and wear resistance.
Uses: Spandex is widely used in underwear and women’s clothing due to its properties. Underwear, casual wear, sportswear, socks, pantyhose, bandages, etc. mainly in the textile field, medical field, etc. Spandex is a highly elastic fiber necessary for high-performance clothing that pursues dynamics and convenience. Spandex can stretch 5-7 times longer than the original shape, so it is comfortable to wear, soft to the touch, wrinkle-free, and can always maintain its original contour.
