Abstract
The invention relates to a method for preparing a nylon 6 FDY (Fully Drawn Yarn) filament. According to the method, high-speed spinning equipment is adopted; and nylon 6 slices, lavender powder microcapsules, anti-oxidant, catalyst and dispersant are taken as raw materials. The method comprises the following steps: step 1, carrying out trickling, blowing laterally and oiling with a screw extruder, a pre-filter, a static mixer, a metering pump and a spinning component; and step 2, rolling with a channel, a first godet, a second godet and a third godet, so as to obtain the FDY filament with a long-lasting faint scent and high stability. The FDY filament can meet different requirements of follow-up weaving, trimming and processing.
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 nylon 6 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 fibers, the objective of the invention is to develop a kind of nylon 6 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 nylon 6 FDY long filament technologies; It is meant on high-speed spinning equipment with nylon 6 slice, lavender powder capsule, anti-oxidant, 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; Weight with nylon 6 slice is benchmark, and the consumption of lavender powder capsule is 1.2-1.8wt%, and the consumption of anti-oxidant is: 0.42-0.75wt%; Catalyst consumption is 1.2-1.8wt%, and the consumption of dispersant is 0.75-1.50wt%.
Wherein, described lavender powder capsule can be in urethane raw, to disperse the formed polyurethane microcapsule of lavender powder, also can other be dispersed with the microcapsules of lavender powder.
Wherein, described anti-oxidant is the triazole type antioxidant BHT.
Wherein, described catalyst is a sodium metasilicate.
Wherein, described dispersant is a PLA.
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 273-275 ℃, and the lateral blowing mode is adopted in cooling, and the blowing wind-warm syndrome is 25-30 ℃; The cooling wind speed is 0.1-0.5 ℃; The speed of first godet roller is 4000-4500 m/min, and the speed of second godet roller is 5000-5500 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 lavender powder capsule raw material; Add specific 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 4.9-5.7 cN/dtex, elongation at break are that 25-40%, elastic recovery rate reach 98-100%.3. through adjustment related process parameter, the nylon 6 FDY long filaments that technology of the present invention is applicable to preparation 20D-70D add delustering agent simultaneously and can prepare corresponding full-dull or half delustring product.
