Abstract
The present invention relates to a spinning process of a polyamide fiber. The polyamide fiber is prepared from raw materials containing polyamide chips, a bamboo carbon microcapsule, an antioxidant, a metal salt catalyst and a dispersing agent on a high-speed spinning device by a process route comprising a screw extruder, a pre-filter, a static mixer, a metering pump, a spinning assembly, flow, side blowing, oil application, a spinning shaft, a first godet, a second godet, a third godet and winding. The prepared FDY filament 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 polyalkylene nylon, the objective of the invention is to develop a kind of polyamide 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 fiber spinning technique; It is meant on high-speed spinning equipment with polyamide section, bamboo charcoal powder microcapsules, anti-oxidant, metal salt catalyst and dispersant is raw material; The process route of employing screw extruder-prefilter-static mixer-measuring pump-filament spinning component-thread-lateral blowing-oil-path-first godet roller-second godet roller-the 3rd godet roller-coiling; It is characterized in that: the weight with the polyamide section is benchmark, and the consumption of bamboo charcoal powder microcapsules is 0.52-0.92wt%, and the consumption of anti-oxidant is: 0.12-0.35wt%; The consumption of metal salt catalyst is 1.25-2.50wt%, and the consumption of dispersant is 0.25-0.70wt%.
Wherein, described bamboo charcoal powder microcapsules can be in urethane raw, to disperse the formed polyurethane microcapsule of bamboo charcoal powder, also can other be dispersed with the microcapsules of bamboo charcoal powder.
Wherein, described anti-oxidant is sulfite anti-oxidant DLTP.
Wherein, described metal salt catalyst is the mixture of zinc acetate and zinc chloride, and the amount ratio of the two is 1:1.
Wherein, described dispersant is Tissuemat E (ACPE).
Wherein, also containing particle diameter in the described raw material is the titanium dioxide fine particles below 3 microns, with preparation FD/SD fiber.
Wherein, Spinning temperature is 272-275 ℃, and the lateral blowing mode is adopted in cooling, and the blowing wind-warm syndrome is 20-30 ℃; The cooling wind speed is 0.1-0.3 ℃; The speed of first godet roller is 4200-4500 m/min, and the speed of second godet roller is 5000-5800 m/min, and the speed of the 3rd godet roller is 5000-5500 m/min.
Compared with prior art; The present invention has following beneficial technical effects: used to 1. the invention property bamboo charcoal powder microcapsules raw material; Add specific metal salt catalyst simultaneously and change the nylon melt structure, prepared the FDY with delicate fragrance fragrance, the fragrance durability is long; And good stability, weave the different demands of arrangement processing after can satisfying.2. spinning technique of the present invention is simple, and production cost is low, and the fibrous fracture intensity for preparing is that 5.0-5.5 cN/dtex, elongation at break are that 25-35%, elastic recovery rate reach 98-100%.3. through adjustment related process parameter, the polyamide FDY long filament that technology of the present invention is applicable to preparation 20D-70D adds delustering agent simultaneously and can prepare corresponding full-dull or half delustring product.
