Abstract
The invention discloses polyester and nylon composite yarn, elastic fabric and a method for producing the elastic fabric. The polyester and nylon composite yarn is air textured yarn, core yarn of the composite yarn is a dacron double-component parallel composite filament, sheath yarn of the composite yarn is a chinlon filament, a 5%-20% filament length difference exists between the sheath yarn and the core yarn, and the content of the core yarn in the composite yarn is 25%-40%. The elastic fabric is made of the polyester and nylon composite air textured yarn and has the advantages of being soft in handfeel, high in elasticity and the like.
Description
Technical field
The present invention relates to a kind ofly to wash bright and beautiful composite air deformation yarn, adopt elastic fabric that this composite yarn forms and the production method of above-mentioned elastic fabric.
Background technology
General more common elastomeric yarn on the market comprises spandex covered yarn, spandex core-spun yarn, polyesters elastomer (as PBT, PTT, parallel type two ingredient elastic fiber) etc., but when these yarn production elastic fabrics of single employing, more or less there is again the problems such as spandex stains, fluffy sense is not enough, feel is not good.
Such as, for the bulkiness of improving terylene wool-like product, the heart yarn employing that someone proposes yarn used has favorable elasticity, easy dyeing, powerful high PET/PTT, as disclosed a kind of functional composite woolly elastic fiber in number of patent application CN201010174971.X, specifically adopt uvioresistant fine denier polyester pre-oriented yarn to carry out after draw false twisting, converge at two roller places and the full drawing-off composite fibre of PET/PTT bi-component parallel type, carry out compound through Network device, make through hot case sizing again, adopt such elastomeric yarn really can avoid spandex staining, because compound tense yarn is parallel feeding, the filament length difference producing between core sheath yarn is smaller, the feel that forms fabric is soft not.
And for example, the bright and beautiful elastic fabric of washing on market is mainly to adopt polyamide fibre FDY coating spandex or polyamide fibre DTY coating spandex to be interwoven with ordinary polyester more now, although the elasticity of this kind fabric is better, in dyeing, exist the problem that very large problem, particularly spandex are stain to be difficult to avoid; And because elastomeric polyurethane fiber is larger, the coil of wrap yarn is easily excessive, affects coverage effect, and uniformity is not good, can cause like this fabric face to occur the phenomenon that striped is inhomogeneous or show money or valuables one carries unintentionally.
Summary of the invention
The object of the present invention is to provide one to wash bright and beautiful composite yarn.
Another object of the present invention is to provide a kind of above-mentioned soft, fine and smooth that bright and beautiful composite yarn forms of washing that adopt, through all good elastic fabric and the production methods thereof of broadwise elasticity.
Technical solution of the present invention is:
Of the present inventionly wash bright and beautiful composite yarn, this composite yarn is the air deformation yarn being formed by common chinlon filament and the two component parallel type bicomponent filament yarns of terylene.Wherein common chinlon filament is as sheath yarn, and the two component parallel type bicomponent filament yarns of terylene, as heart yarn, have 5%～20% filament length difference between sheath yarn and heart yarn, and the content of heart yarn in composite yarn is 25～40%.
The two component parallel type bicomponent filament yarns of terylene used are specially PET/PTT, High Viscosity PET/low viscosity PET, PET/PBT etc., preferably PET/PTT.
If heart yarn content is lower than 25% in composite yarn, the fabric elasticity deficiency forming; And heart yarn content is higher than 40%, certainly will will be less than 60% as the polyamide fibre content of sheath yarn use, the fabric forming just can not embody the feel of the peculiar softness of nylon fabric.If the filament length difference between composite yarn mesotheca yarn and heart yarn is lower than 5%, the fabric forming does not have cotton sense; And filament length difference is higher than 20%, the cotton sense of fabric is too strong, and can cause the snag of fabric, balling-up physical property bad.
The common non-resilient chinlon filament of washing chinlon filament in bright and beautiful composite yarn and be preferably half delustring or full-dull of the present invention.
Consider the feel of fabric, the initial modulus of washing bright and beautiful composite yarn of the present invention is 2.0～3.2cN/dtex.
Fiber number of washing bright and beautiful composite yarn of the present invention is 75～150dtex, and the twist is 0～1000T/M.
Production method of washing bright and beautiful composite yarn of the present invention is as follows, and using chinlon filament as sheath yarn, the two component parallel type bicomponent filament yarns of terylene feed respectively in air-texturing jet as heart yarn, produce distortion and make through airflow function; Wherein the over feed rate(OFR) of heart yarn is 5%～10%, and the over feed rate(OFR) of sheath yarn is 10%～20%, overfeeding rate variance is 5%～10%, and tonnage 8～10kg, hot plate temperature are 160～180 DEG C.
According to JIS L 1096 standards, adopt being more than 10%, being more than 80% through broadwise elastic recovery rate through broadwise elastic extension of elastic fabric that bright and beautiful composite yarn forms of washing of the present invention.According to KES test, the bending stiffness B value of this elastic fabric is 0.04～0.08N.cm
2below/cm.
Consider the physical property such as the elasticity of fabric and wash shrinkage, snag, balling-up, the tightness of elastic fabric of the present invention is 1500～2500.
The concrete production method of elastic fabric of the present invention is as follows:
Weave: by above-mentioned washing bright and beautiful composite air deformation yarn and first carrying out the twisting of 300～600T/M of making, then set it as through weft yarn and weave on water jet looms, revolution speed is 400～600rpm, and loom warp tension is 1200～1800N.
After dyeing, arrange and comprise refining, dyeing, resin finishing and arrange sizing.Crispatura as the parallel type bicomponent filament yarn of heart yarn by above-mentioned processing, it is large that web contraction becomes, and then guaranteed the elastic performance of fabric.
Refining: 90～95 DEG C of temperature, alkaline agent concentration are that 5～10g/L, refining agent concentration are 4～12g/L.Refining speed determines according to the thickness of cloth and refining effect, and speed is generally 40～60m/min.
Dyeing: be mainly to adopt dispersion/ACID DYES single bath process to carry out, Primary regulation pH value is that 4～6,110 DEG C × 40～60min, bath raio are 1:15～30.
Resin finishing: utilize resin finishing agent to improve its feel, increase its fluffy sense and flexibility.Preferably amino-modified silicone resinoid.
Rear arrangement sizing: 160～180 DEG C of setting temperatures, adopt framing shaping machine.
The present invention washs the spandex that product that bright and beautiful composite air deformation yarn forms can solve spandex class elastic fabric stains problem, has feature soft, excellent spring.
Detailed description of the invention
Below in conjunction with embodiment and comparative example, the invention will be further described, but protection scope of the present invention is not limited to this.
In embodiment 1～5 and comparative example 1～2, the soft finishing agent TF-437 of resin finishing super bullet used, bulkiness finishing agent TF-438 are development of evil in febrile disease joint-stock company and produce.
