Abstract
The invention relates to a nylon 6/spandex coated yarn. The nylon 6/spandex coated yarn is made by steps of using nylon 6 chips and additives as raw materials, preparing a fine-denier nylon 6 POY (pre-oriented yarn), using a naked spandex filament yarn as a core yarn and using the fine-denier nylon 6 POY as a skin yarn to prepare the polyester/spandex coated yarn by means of the ATY (air-jet texturing yarn) process. The nylon 6/spandex coated yarn has excellent handfeel and appearance when being used for production of woven fabrics or knitted fabrics and has excellent mixed color effects in dyeing.
Description
Technical field
The invention belongs to the spinning material field, be specifically related to a kind of employing POY-ATY prepared nylon 6/ polyurethane covered yarn.
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 and poly fibre 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.
Polyurethane elastomeric fiber is a kind ofly to contain 85% above carbamate, have the fiber that the block macromolecular compound of linear chain segment structure is processed, and the Chinese commodity name is called spandex, is a kind of synthetic fiber of excellent performance.Spandex fibre is developed in nineteen thirty-seven by Bayer A.G at first, realizes suitability for industrialized production by du pont company at first in nineteen fifty-nine.It is big that spandex has an elongation at break, and elastic recovery rate is high, and fatigue performance is good, and density is low, and is heat-resisting, sun-proof and anti-aging.
Summary of the invention
In order to satisfy diversity, comfortableness, the functional requirement of people to clothes, continually develop out novel functional fiber, the objective of the invention is to exploitation and have functional composite spun fiber.
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/ polyurethane covered yarn; It is to be raw material with nylon 6 slice and additive; At first preparing fine denier nylon 6POY pre-oriented yarn, is heart yarn with bare spandex filament then, is that the crust yarn adopts described nylon 6/ polyurethane covered yarn of ATY prepared with fine denier nylon 6POY pre-oriented yarn; It is characterized in that: the specification of described bare spandex filament is 40D, and the specification of described nylon 6POY pre-oriented yarn is 70D/24f.
Wherein, In described POY technology, described technological process comprises: screw extruder-prefilter-distributing pipe-measuring pump-filament spinning component-spray silk-lateral blowing oils-path-POY pre-oriented yarn, and spinning temperature is 278-290 ℃; The lateral blowing mode is adopted in cooling; The blowing wind-warm syndrome is 20-25 ℃, and the cooling wind speed is 0.3-0.7 ℃, and winding speed is 3000-3500 m/min; In described ATY technology, air-texturing pressure is 12-15 kgf/cm
2, heat setting temperature is 180-210 ℃.
Wherein, in described POY technology, be benchmark with the weight of nylon 6 slice, described additive comprises: the consumption of bamboo charcoal powder microcapsules is 0.4-0.8wt%, and the consumption of anti-oxidant is: 0.15-0.25wt%, MgCl
2Consumption be 0.8-1.2wt%, FeSO
4Consumption be 0.4-0.6 wt%, the consumption of dispersant is 0.5-1.0wt%.
Wherein, described bamboo charcoal powder microcapsules are in urethane raw, to disperse the formed polyurethane microcapsule of bamboo charcoal powder.
