Description
Technical field
The utility model belongs to weaving polyester complex fiber technical field, is specifically related to a kind of polyester elastomer/PET composite elastic fiber.
Background technology
Current spandex, as the hat of elastomer, has been widely used in hosiery, swimsuit, interior nightwear, sportswear, fashionable dress coat and health care product aspect.But elastic spandex fiber production equipment and process is complicated, raw material and processing cost high, expensive, there are " three wastes " to pollute, can not chlorine drift, dyeing difficult, high temperature problems such as fiber easily fuses, cloth there will be " showing money or valuables one carries unintentionally " and " foaming " phenomenon when stretching, elasticity surplus, comfortableness are poor when arranging when simultaneously fiber exists dyeing and finishing.
In order to solve this series of problems that spandex fibre exists, in recent years, market occurs with bi-component polytrimethylene terephthalate (PTT) and T400 be the composite elastic fiber of representative.These two kinds of fibers are all obtained by polyethylene terephthalate (PET) and PTT composite spinning.Wherein bicomponet PTT is the product of Shell Co. Ltd's exploitation, and the elastomer of T400 Shi Ying Radar Audio Company exploitation, due to PTT expensive raw material price, cause these two kinds of composite fibre prices all very high.
In addition, also some two component composite elastic fibers are reported in document, a kind of PET composite elastic fiber and preparation method thereof disclosed in CN104141178, the method is the two kinds of PET sections utilizing different viscosities, by after melting compound spray silk through quenching, oil, reel, draw and make as-spun fibre, as-spun fibre obtains finished product long filament through overbalance, stretching, sizing again.Because the method adopts two kinds of PET of different viscosities to be the poor flexibility of composite spinning raw material, its gained composite fibre, crimp elasticity only 55 ~ 70%, fracture strength is low, is less than 2cN/dtex.
And for example a kind of parallel composite elastic fiber and manufacture method thereof disclosed in CN101851812, the method be by polybutylene terephthalate (PBT) and polyethylene terephthalate with 70: 30 ~ 30: 70 weight ratio carry out composite spinning arranged side by side after obtained pre-oriented yarn (being called for short POY), POY silk is again through the obtained parallel composite finished fiber of false twisting processing (being called for short DTY), and this fiber only has low elasticity.
For another example CN103882538 discloses a kind of new elastic fiber and preparation method thereof, the raw material that the method adopts is PTT, PET, ECDP (normal pressure cation dyeable polyester) and different viscosities PET, what technique adopted is fullly drawn yarn (FDY) (FDY) technique, it not only needs the composite elastic fiber by just can be prepared into finished product after the tensile fiber be spun into through 95 ~ 100 DEG C of boiling water treating 15 ~ 20min, and the crimpness of fiber is only 43 ~ 55%, elasticity wretched insufficiency.
