Abstract

The invention provides a composite yarn, cloth knitted thereby and a manufacturing method thereof. The composite yarn is a ring spun yarn formed by twisting a DTY (Draw Textured Yarn) and a POY (Polyester Pre-Oriented Yarn), wherein the twist is 700-800 T/M; the DTY is a 75D/48F yarn; the POY is a 75D/72F yarn; the ring spun yarn is a 160D/120F yarn. The invention also provides a piece of anti-pilling cotton knitted cloth and a manufacturing method thereof. The cloth is knitted by the composite yarn, feels soft on the surface, has favorable draping property and high anti-pilling performance and is greatly increased in the using effect. The cotton-like yarn is far lower in price than a cotton yarn and has a broad application prospect.

Description

Complex yarn and the cloth and the manufacture method thereof that are formed by this yarn knitting

Technical field

The cloth and the manufacture method thereof that the present invention relates to a kind of complex yarn and formed by this yarn knitting.

Background technology

Imitative cotton fiber is one of emphasis development project in country's 12 planning.Existing imitative cotton is generally to be formed by weaving with terylene short fiber, such as Du Pont's terylene short fiber, but Du Pont's short fiber in order to pursue feel, Yarn filoplume is longer, so the fabric pilling tendency is poor, has a strong impact on service life and the aesthetics of product; The yarn that twisting type terylene short fiber is formed by weaving overcome the relatively poor characteristic of balling-up, but feel is harder, the not obvious and easy folding line of dyeing fabric of imitative cotton advantage; High-grade imitative cotton, cotton as imitative in Du Pont also exists price relatively costly, universal face deficiency less than normal.This is the defective of prior art.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of possess cotton feel, complex yarn and knitted cloth that anti-pilling is high.

Complex yarn of the present invention for by a DTY spun polyester thread and a POY spun polyester thread, passes through the ring spinning line that the composite twisting machine twisted filament forms, and wherein the twist is positioned at 600-800T/M.

Described DTY spun polyester thread is the 75D/48F yarn; The POY spun polyester thread is the 75D/72F yarn; The RING SPINNING complex yarn is the 160D/120F yarn.

The present invention also provides the cotton sense of a kind of ANTIPILLING knitted cloth, and this cloth forms by described complex yarn is knitting.

The present invention also provides a kind of manufacture method of knitted cloth, the operation that comprises twisted filament, described twisted filament operation are by a DTY spun polyester thread and a POY spun polyester thread, make the ring spinning line complex yarn through composite twisting machine, wherein, the twist is positioned at 600-800T/M.

Complex yarn of the present invention is because the yarn twisted filament with different shrinkage rates forms, thereby by the knitting fabric surface touch softness that forms of this complex yarn, fabric degree of dangling is good; Also due to the special construction of this RING SPINNING complex yarn, have high anti-pilling, greatly increase the fabric result of use; The a little higher than spun polyester thread of imitative cotton price of the present invention well below the cotton yarn price, lower than the imitative cotton of the Du Pont of top grade, is with a wide range of applications especially.

The specific embodiment

Now in conjunction with the accompanying drawings and embodiments the present invention is described in further detail.

Referring to Fig. 1, the invention provides the cotton sense of a kind of ANTIPILLING knitted cloth, it forms by the RING SPINNING complex yarn is knitting, this RING SPINNING complex yarn is by the heavy net height elater of a DTY() spun polyester thread 10 and a POY(pre-oriented yarn) spun polyester thread 20, twisted filament forms through composite twisting machine, in the twisted filament process, it is necessary that the twist is positioned at 600-800T/M.

Preferred embodiment of the present invention is that above-mentioned DTY spun polyester thread 10 is 75D/48F yarns; POY spun polyester thread 20 is 75D/72F yarns; Described RING SPINNING complex yarn is the 160D/120F yarn.

Although yarn 10 of the present invention, 20 is same spun polyester threads, they have different shrinkage rates, thereby soft by the knitting fabric surface touch that forms of this complex yarn, and fabric degree of dangling is good.Also due to the special construction of this RING SPINNING complex yarn, have high anti-pilling, Guangzhou Minister of the General Administration for Quality Supervision test result can reach the 4-5 level, greatly increases the fabric result of use.

The a little higher than spun polyester thread of imitative cotton price of the present invention well below the cotton yarn price, lower than the imitative cotton of the Du Pont of top grade, is with a wide range of applications especially.

The production technology of the cotton sense of ANTIPILLING of the present invention knitted cloth is as follows:

1. prepare the step of yarn: the operation that comprises imitative staple, reeling, twisted filament, steaming cylinder, warping, slurry silk, twisted filament operation wherein is by the heavy net height elater of a DTY() 75D/72F and a POY(pre-oriented yarn) 75D/48F, through the ring spinning line 160D/120F complex yarn that composite twisting machine is made, the twist necessary (600-800T/M);

2. knitting step, wherein fabric manufacture equipment used is basic single-side machine forever, 34G, barrel dliameter 32 ";

3. the step of refining: refining equipment used is L overflow type power dyeing machine in heptan, referring to Fig. 2, the operation of refining is: (1) warm water infiltrates 1A(5min)--intensification 2A(2-3 ℃/min)--be incubated 3A(100 ℃ of * 60min)-lower the temperature 4A(20 ℃/min)--draining-cold wash 5A(60 ℃ * 10min) (2) add liquid caustic soda 2%, refining agent 2g/l;

4. the step that dyes, wherein dyeing installation used is L overflow type power dyeing machine in heptan, referring to Fig. 3, the operation of dyeing is: when warm water infiltrates (50 ℃ of * 10min) 1B-the enter to dye-dyeing 2B that progressively heats up (the 1.5 ℃/min that heats up-when temperature is raised to 90 ℃)-3B (5min)-intensification 4B(1 ℃ of insulation dyeing/min to 125 ℃)-insulation 5B (55min)--when lowering the temperature 6B(2 ℃/min to 80 ℃)--draining-reduction cleaning 7B

5. the step of finalizing the design, modular system used is stentering boarding machine, and the operation of typing is that (1) has added crude oil (pick-up 70%-80%) (2) to formalize at 160 ℃ of temperature in mangle, and the setting speed of a motor vehicle is 20m/min;

6. the brush comb is cut the step of shaking, and it is Italian flying horse 32 rollers that brush comb used is cut equipment, two loopers, two-way frequency conversion, wherein brush: first cross 3 groups by 36 roller brushing machines, crossing 6 groups by 24 roller brushing machines, guarantee the dense softness of bristle effect; Comb: machine speed is adjusted into 25m/min; Cut: the high 1cm of being left of hair; Shake: 110 ℃ of * 30 min;

7. the step of finalizing the design afterwards, modular system used is framing shaping machine, 160 ℃ of setting temperatures, typing speed of a motor vehicle 20m/min.

The finished product grammes per square metre 280g/m2 of the cotton sense of the ANTIPILLING so made knitted cloth, door 60 ".
