Abstract
The invention provides a composite fiber, which is prepared by compounding the high shrinkage FDY and the fine denier PET low-elastic yarn, the high shrinkage FDY directly passes through the bypass yarn path of a compound elasticizer with a zero roller and is compounded on a second roller part, and the boiling water shrinkage of the high shrinkage FDY is larger than 20%.The composite fiber is composed of 50 % of the high shrinkage FDY and 50 % of the fine denier PET low-elastic yarn; the high shrinkage FDY is prepared by using an FDY spinning device of which the specification is 30D/12F, and the fine denier PET low-elastic yarn is prepared by false twisting POY produced by a circular air blow cooling spinning device of which the specification is 75D/144F.The product has the advantages of excellent performance, smooth post processing, comfort handfeel and lowered product cost, can achieve good velvet effect, and can be used as a raw material for automobile decorative fabric with high grade and perfect performance.
Description
Technical field
The present invention relates to a kind of composite fibre, specifically is that a kind of high-shrinkage polyester full-drawn yarn and fine denier polyester low-stretch yarn are compound.
Background technology
Terylene is as one of the big main force of three in synthetic fiber fiber, because of its good physics and chemical characteristic are widely used in garment material and other non-garment industry.The terylen product since coming out, also once with its drapability is good, intensity is high, well-pressed, be difficult for becoming and be used as main textile raw material by downstream user and weave all kinds of textiless.As the raw material of vehicle internal decoration cloth, mainly be three kinds of terylene fully drawn yarn tricot, super fine denier fabric or nonwoven fabric, but product specification is low, performance is imperfect, and the defect ware rate of process is higher, the difficult control of product cost.
Summary of the invention
The purpose of this invention is to provide a kind of composite fibre, is to be composited by high-shrinkage polyester full-drawn yarn and fine denier polyester low-stretch yarn, is used for the raw material of vehicle internal decoration cloth, the class height, and the performance perfection is processed smooth and easyly, reduces production costs.
Purpose of the present invention is achieved through the following technical solutions:
Composite fibre, be composited by high-shrinkage polyester full-drawn yarn and fine denier polyester low-stretch yarn, the high-shrinkage polyester full-drawn yarn directly by have zero roller can compound elasticizer bypass silk road carry out compoundly at two roller places, the boiling water shrinkage of high-shrinkage polyester full-drawn yarn is greater than 20%.
The described high-shrinkage polyester full-drawn yarn that consists of is 50%, and the fine denier polyester low-stretch yarn is 50%;
Described high-shrinkage polyester full-drawn yarn utilizes the FDY device for spinning to make, and specification is 30D/12F; The fine denier polyester low-stretch yarn is to adopt the POY that encircles the production of blowing cooling device for spinning to carry out false twisting again to make, and specification is 75D/144F;
Technological process is:
POY → original silk rack → the cut hot case → coldplate of a device → first roller → twist arrester → first → false twister
High FDY → original silk rack → a cut device → zero roller that shrinks
→ the second roller → Network device → auxiliary roller → second hot case → the 3rd roller → device → the spy silk oils roller → coiling
For keeping the high boiling water shrinkage of high-shrinkage polyester full-drawn yarn, the temperature of the second hot case is very low.
The advantage of product of the present invention is: excellent product performance, and back processing is smooth and easy, reduces production costs, and can reach good suede class effect after the processing, and comfortable feel is used for the raw material of vehicle internal decoration cloth, class height, performance perfection.
The specific embodiment
Further specify product of the present invention by specific embodiment:
Produce the high-shrinkage polyester drafted fibre of 33dtex/12F, by p-phthalic acid and ethylene glycol esterification reaction, be that 0.650 polyester fondant carries out direct fabrics through the poly-preparation of precondensation and final minification viscosity again, adopt the production of new high-efficiency up-coiler, pipe temperature is 290 ℃ during melt Conveying, 293.5 ℃ of spin manifold temperatures, the spinnerets specification is selected PRB56-12-0.26*0.60 for use, metal sand proportioning 60-80 order: 100 μ m/g, 80-100 order: 25 μ m/g, make component pressure reach 135bar, guarantee the normal wire vent of spinnerets, adopt the lateral blowing mode to cool off, the pressure of lateral blowing is 560pa, 23 ℃ of temperature, humidity 90%, wind speed 0.5m/s, oil frame height 1100mm, adopt the oil nozzle mode that oils, use valid density is 90% finish, and the rate of oiling is 1.00%, guarantees the obvolvent performance between the monofilament; Winding speed is that the speed of 4700m/min, first hot-rolling is that 2050m/min, temperature are 83 ℃, and the speed of second hot-rolling is that 4750m/min, temperature are 134 ℃, and the spinning tension 5.5CN of tow, winding tension are 8.0CN; For guaranteeing the forming of POY spinning cake, the coiling start angle is made as 5.5 ° and is being wound up into 130mm, 135mm, 140mm, 150mm, 170mm, 190mm, 210mm, winding angle is made as 5.6 ° respectively during 388mm thickness, 5.7 °, 5.9 °, 6.0 °, 6.1 °, 6.0 °, 5.9 °, 5.8 °, the winding angle that full volume switches is made as 5.5 °, initial contact pressure is made as 130N, at 94mm, 140mm, 200mm, 280mm, 320mm, 360mm, 400mm, during 430mm thickness, contact pressure all is made as 130N, automatically switch when completely rolling up, spinning cake is delivered to quality testing check physical index and appearance test, detect and qualified after move to false twisting and 144dtx/144f the DTY of POY by the 83dtx/144f that adds the production of bullet flow process of routine carry out compound.The high polyester drawn yarns that shrinks be directly by have zero roller can be compound bypass silk road carry out compound at two roller places, compound back is producing the composite fibre of 116dtex/156f specification through the second roller → Network device → auxiliary roller → second hot case → the 3rd roller → spy silk device → roller that oils → coiling, for keeping the high boiling water shrinkage of high-shrinkage polyester full-drawn yarn, the temperature of the second hot case is between 30～0 ℃.
The excellent product performance that the present invention produces, rear processing is smooth and easy, reduces production costs, and can reach good suede class effect after the processing, and comfortable feel is for the raw material of vehicle internal decoration cloth, class height, performance perfection.
