My company has successfully developed PTT fiber
PTT fiber is to get together of terephthalic acid propylene glycol esters fiber abbreviation, was made by the Shell Chemical (Shell Chemical company) in 1995 of the successful development of the new spinning polymer. PTT fiber and PET (poly of terephthalic acid b two ester) fiber, PBT, (poly succinic terephthalic acid ester) fiber belong to polyester fiber, from similar a polymer spinning. PTT polyester and polyamide fiber has the characteristics, except antifouling performance good outside, and easy to dyeing, feel soft, elastic, elongation of polyurethane fiber with as good and spandex elastic fiber more easily than processing, very suitable for textile fabric; Besides PTT also has is dry, tinggua etc. Characteristics. Therefore, in the near future, PTT fiber will gradually replace polyester and polyamide fiber and become a large fiber in the 21 st century.
PTT fiber has the stability of the nylon polyester and flexibility, its expression in:
1, PTT fabric soft and have excellent hanging sex.
2, PTT fabric has comfortable elastic (better than polyester PET, gather PBT PP fiber and polypropylene ester PBT, and nylon 6 or nylon 66 fiber quite).
3, PTT fabric has superior elongation restorative (20% still can restore the elongation of the original length).
4, PTT has excellent dyeing and printing characteristics (110 ℃ ~ 120 ℃, general dispersal dyes can dyeing); The superior colour fastness, insolation fastness and fight corrupt sex.
5, PTT fabric has bright color and iron free sex.
6, PTT is more extensive adaptability. PTT suitable for pure spinning and cellulose fiber or and natural fiber, synthetic fiber composite, production carpet, plainclothes, fashion, underwear, sports, swimsuit, and socks.
Gather succinic terephthalic acid ester (polytetramethylene), PTT, this fiber strength for 30.91 ~ 35.32 cN/Tex, elongation at break 30% ~ 60%, melting point for 223 ℃, its crystallized faster than terephthalic acid ester together second 2 10 times faster, with excellent elongation elastic recovery rate and soft and easy dyeing characteristic. And can also terephthalic acid esters, second 2 together, polypropylene composite spinning with polyamide, polyester, or of polypropylene and blended yarn, fiber strength 2.7 ~ 4.5 cN/dtex. PTT fiber polymerization, spinning, machining deformation process route and ordinary polyester production basic same, if he transformation, can use polyester production equipment production PBT fiber.
Made by PTT fiber with some of the properties of polyester fiber, but because of the PTT macromolecular basic chain link flexibility of the part is longer and make PBT fiber melting point and glass transition temperature than ordinary polyester fiber for low, leading to large molecules of flexible and fiber chain elastic improved.
Generally speaking, PTT fiber has the following some features:
Have good durability, dimensional stability and good flexibility and elasticity from moisture influence.
PTT fiber and its products feel soft, hygroscopicity, wear resistance and fiber is of good curly, tensile elastic compression and extremely flexible, the elastic recovery rate is better than the polyester. PTT fiber in dry wet state has special conditions are flexible, and stretch from the ambient temperature change effects, the price is far lower than the spandex fiber.
Have good dyeing performance, use common dispersal dyes for atmospheric boiling dye, without carrier. Littered fiber bright color, the color fastness and resistance to chlorine sex is good.
With excellent anticorrosion chemical resistance, resistance to light sex and heat resistance.
PTT and PET composite fiber has the fine and dense stereo curly, superior recovery, soft and good dyeing performance, is the ideal wool-like, feather raw material, comfortable to wear.
