Abstract
The present invention relates to a process for a chinlon 6 DTY high elastic yarn. The chinlon 6 DTY high elastic yarn is prepared from raw materials comprising polyamide 6 chips, a tulip powder capsule, an antioxidant, a metal salt catalyst and a dispersant by a POY-DTY process. The prepared DTY high elastic yarn has fresh and long-lasting fragrance and good stability, and can meet different requirements of post-weaving finishing.
Description
Technical field
The invention belongs to the spinning material field, be specifically related to a kind of the section and produce the spinning technique of polyamide fiber.
Background technology
Take synthetic fiber at present terylene (polyester), polyamide fibre (polyamide), polypropylene fibre (polypropylene), spandex (polyurethane), acrylic fibers (polyacrylonitrile) etc. are generally arranged.These fibers have different qualities, thereby different purposes is also arranged.But at present general wearing fabric, because its fiber is thicker, feel is coarse, flexibility is poor, gas permeability is poor, water imbibition is poor, be easy to pilling.The Along with people's growth in the living standard, also increasingly high for the dress requirement of textiles.
Polyamide fiber is the synthetic fiber kind that drops into suitability for industrialized production in the world the earliest; It is to be raw material by aliphatic dibasic acid and diamine or aliphatic amino acid through the synthetic polyamide of polycondensation reaction, again through the general name of the prepared one type of synthetic fiber of melt spinning.Owing to all contain amido link therein, so be referred to as polyamide fiber.It belongs to a kind of of heterochain class synthetic fiber.Wherein the output with polycaprolactone nylon (Nylon6, polyamide fibre 6, polyamide 6) and poly fibre (Nylon66, polyamide fibre 66, polyamide 66) is maximum, uses the widest.Polyamide fibre is not only industrialized the earliest synthetic fiber kind; And it also has multiple good characteristic; It has higher intensity, elasticity, and wear-resisting weather resisteant is good, thereby the consumers in general's that experience welcome; But along with improving constantly of living standards of the people, people to the diversity of clothes, comfortableness, functional requirement also more and more widely.Fiber finer dawnization, functionalization are important directions of fibre in differentiation development, also are the main development trends of polyamide fiber spinning.Compare with conventional polyamide fibre, differential nylon fibre has more excellent performance: gas permeability, compliance, comfortableness, dyeability, functional etc., exploitation variety classes, just like a raging fire the carrying out of research novel, the functional polyalkylene nylon.
Summary of the invention
In order to satisfy diversity, comfortableness, the functional requirement of people to clothes, continually develop out novel functional nylon-6 fiber, the objective of the invention is to develop a kind of nylon-6 fiber with aromatic function.
