[background technology]
Ptt fiber is the english abbreviation of poly terephthalic acid 1.3 propylene glycol ester (English is polytrimethylene-tereph-thalate) fiber, respectively from petroleum technology route and biology corn process route is polymerized by PTA and PDO, spinning is made new type polyester fiber the earliest by ShellChemical (Shell Chemical Co) and du pont company, the trade name of Shell is the trade name of Corterra, Dupont is Sorona.The raw material PDO wherein i.e. cost of 1,3 propylene glycol is higher, nowadays refines cost with corn and declines to some extent.Due to the introducing of PDO, make fibre structure there has been a methylene-ch2-, thus fiber in the shape of a spiral, Here it is, and ptt fiber has flexible reason.
Ptt fiber and PET (polyethylene terephthalate) fiber, PBT (poly terephthalic acid 1.4 butanediol ester) fiber belong to polyester fiber together.Ptt fiber has the characteristic of terylene, polyamide fibre, acrylic fibers concurrently, except antifouling property well except, be easy to dyeing, soft, high resilience in addition, extensibility is equally good with spandex fibre, is easier to process compared with elastomer spandex, very applicable textile garment fabric; PTT also has the features such as dry and comfortable, well-pressed in addition.Therefore, in the near future, ptt fiber progressively will substitute terylene and polyamide fibre and become 21 century large fiber type.
Ptt fiber has the stability of terylene and the flexibility of polyamide fibre, and it shows:
1, PTT fabric sofetening and there is excellent vertical property.
2, PTT fabric have comfortable elasticity (be better than terylene PET, polybutylene terephthalate (PBT) PBT and polypropylene PP fiber, with nylon 6 or nylon 66 fiber suitable).
3, PTT fabric has excellent elongation restorative (extend 20% and still can recover its original length).
4, PTT has excellent dyeing and Printing Characteristics (98 DEG C-110 DEG C General Decentralized dyestuffs can dye); Superior dyefastness, light fastness and pollution resistance.
5, PTT fabric has chromatic colour and easy-care properties.
6, PTT adaptability is more extensive.PTT be applicable to pure spin or with cellulose fibre and natural fabric, synthetic fiber compound, produce carpet, plain clothes, fashionable dress, underwear, sweat shirt, swimsuit and socks.
