Description

A kind of polyamide fibre 66 DTY false-twist textured yarn technologies

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 66 nylon fiber, the objective of the invention is to develop a kind of 66 nylon fiber with aromatic function.

In order to solve the above-mentioned technical problem that exists in the prior art, reach the described purpose of invention, the present invention has adopted following technical scheme:

A kind of polyamide fibre 66 DTY false-twist textured yarn technologies; It is meant with polyamide fibre 66 sections, thiazole aromatic, anti-oxidant, metal salt catalyst and dispersant is that raw material adopts the manufacturing of POY-DTY technology; It is characterized in that: the weight with polyamide fibre 66 sections is benchmark; The consumption of thiazole aromatic is 0.15-0.25wt%, and the consumption of anti-oxidant is: 0.30-0.60wt%, and catalyst consumption is 0.72-1.50wt%; The consumption of delustering agent is 0.75-2.0wt%, and the consumption of dispersant is 0.75-1.5wt%.

Wherein, in said POY-DTY technology, the process route of POY is: screw extruder → prefilter → static mixer → measuring pump → filament spinning component → spray silk → lateral blowing oils → path → POY undrawn yarn; Wherein: spinning temperature: 272-280 ℃; The lateral blowing condition: wind speed is 0.2-0.5 m/s, wind-warm syndrome 20-30 ℃, relative humidity 60-75%; The rate of oiling is 0.70-1.50%; Spinning speed is 3500-4500 m/min; Wherein, the DTY production process route is: the hot case → coldplate of thread guide → feeding roller → first → false twister → delivery roller → oiling device → DTY undrawn yarn; Wherein, first heater temperature is 150-175 ℃, and D/Y ratio is 1. 2-1.5, and drafting multiple is 1.15-1.30.

Wherein, described thiazole aromatic is 2,4,5-trimethylthiazole or 2-isobutyl pyrazine.

Wherein, described anti-oxidant is sulfite anti-oxidant DLTP.

Wherein, described catalyst is the mixture of sodium fluoride and sodium metasilicate, and the amount ratio of the two is 1:1.

Wherein, described dispersant is a polycaprolactone.

Wherein, described delustering agent is a titanium dioxide fine particles.

Compared with prior art; The present invention has following beneficial technical effects: used to 1. the invention property thiazole aromatics raw material; Add specific metal salt catalyst simultaneously and change the nylon melt structure, prepared the DTY false-twist textured yarn with delicate fragrance fragrance, the fragrance durability is long; And good stability, weave the different demands of arrangement processing after can satisfying.2. through adjustment related process parameter, the polyamide fibre 66 DTY false-twist textured yarns that technology of the present invention is applicable to preparation 20D-70D add delustering agent simultaneously and can prepare corresponding full-dull false-twist textured yarn.
