Abstract
The invention relates to polyester/spandex-coated yarn with anti-static and anti-bacterial functions, which is made of polyester slices and additives, and is prepared according to the following steps: firstly, preparing fine denier polyester POY (pre-oriented yarn), and secondly, preparing the polyester/spandex-coated yarn by taking naked spandex filaments as heart yarn and taking the fine denier polyester POY as surface yarn according to an ATY (Airjet Textured Yarn) technology. The coated yarn prepared according to the invention feels and looks excellent when used for producing woven fabric or knitted fabric, and is wonderful in color mixing effect during dyeing.
Description
Technical field
The invention belongs to the spinning material field, be specifically related to a kind of polyester/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.
Polyester fiber is with terephthalic acid (TPA) or dimethyl terephthalate (DMT) and ethylene glycol fiber-forming polymer-PETG that to be raw material make through polycondensation reaction through over-churning or ester exchange again, the fiber of processing through spinning and post processing.Because contain ester group in the molecular structure so be called polyester fiber.Along with the World Science development of technology, the output of polyester fiber increases fast, but on performance and function, can't satisfy people's requirement, and people have developed large quantities of differential, functionalization and high performance polyester fiber.Aspect polyester fiber like ultra bulkiness fiber, ultra drapability fiber, ultra-flexible fiber, fragrance fiber, radiation resistant fiber etc.U.S.'s immediate development is closed fine kind and is mainly contained elastomer, industrial silk, carpet etc.In the exploitation of not only paying attention to polyester industrial fiber and nonwoven material aspect the polyester fiber product development; And pay attention to exploitation and the multiple fibre in differentiation of dress ornament with polyester fiber, as improve the gloss of fiber, add different additive; The fiber of different cross section shape; Different number of fiber, polyester flame-retardant long filament, hollow polyester filament and low-melting point polyester long filament.
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 polyester/polyurethane covered yarn of antistatic, antibacterial functions; It is to be raw material with polyester slice and additive; At first preparing fine-denier polyester POY pre-oriented yarn, is heart yarn with bare spandex filament then, is that the crust yarn adopts the described polyester/polyurethane covered yarn of ATY prepared with fine-denier polyester POY pre-oriented yarn; It is characterized in that: the specification of described bare spandex filament is 20D, and the specification of described polyester POY pre-oriented yarn is 50D/72f; Wherein, in described POY technology, described technological process comprises: polyester slice-drying-screw extruder-prefilter-distributing pipe-measuring pump-filament spinning component-spray silk-lateral blowing oils-path-POY pre-oriented yarn; And the intrinsic viscosity of polyester slice is 0.65; Spinning temperature is 290-292 ℃, and the lateral blowing mode is adopted in cooling, and the blowing wind-warm syndrome is 20-25 ℃; The cooling wind speed is 0.3-0.5 ℃, and winding speed is 3000-3200 m/min; In described ATY technology, air-texturing pressure is 16-18kgf/cm
2, heat setting temperature is 215-225 ℃.
Wherein, in described POY technology, be benchmark with the weight of polyester slice; The silver molecular sieve of 0.20-0.25wt% or zeolite, the antioxidant of 0.15-0.25wt%, the magnesium sulfate of 0.6-1.0wt%; 0.4-0.6 the nickelous sulfate of wt%, the dispersant of 0.5-1. 0wt%.
Wherein, described anti-oxidant is alkylation bis-phenol or thiobisphenol.
Wherein, described dispersant is polyethylene glycol or Tissuemat E.
The covering filament of the present invention preparation can show the feel and the outward appearance of excellence when being used for the production of woven fabric or knitted fabric, and when dyeing, can demonstrate fabulous mixed color effect.
