Introduction to new fiber – PTT fiber
PTT fiber is the abbreviation of polytrimethylene terephthalate fiber. It is a new spinning polymer successfully developed by Shell Chemical of the United States in 1995. PTT fiber, PET (polyethylene terephthalate) fiber and PBT (polybutylene terephthalate) fiber are both polyester fibers and are spun from similar polymers. PTT fiber has the characteristics of both polyester and nylon. In addition to good anti-fouling properties, it is easy to dye, soft to the touch, and elastic. Its elongation is as good as spandex fiber. Compared with elastic fiber spandex, it is easier to process and is very suitable for textiles. Clothing fabric; in addition, PTT also has the characteristics of dryness and crispness. Therefore, in the near future, PTT fiber will gradually replace polyester and nylon and become the large-scale fiber in the 21st century.
PTT fiber has the stability of polyester and the softness of nylon, which is reflected in:
1. PTT fabric is soft and has excellent drape.
2. PTT fabric has comfortable elasticity (better than polyester PET, polybutylene terephthalate PBT and polypropylene PP fiber, and equivalent to nylon 6 or nylon 66 fiber).
3. PTT fabric has excellent elongation recovery (it can still restore its original length after being stretched by 20%).
4. PTT has excellent dyeing and printing properties (110℃~120℃, general disperse dyes can be dyed); excellent dyeing fastness, light fastness and stain resistance.
5. PTT fabric has bright colors and is easy to iron.
6. PTT has a wide range of adaptability. PTT is suitable for pure spinning or compounding with cellulose fiber, natural fiber and synthetic fiber to produce carpets, casual clothes, fashionable clothes, underwear, sportswear, swimwear and socks AAFSGRETEGSDFW
