Abstract

The present invention relates to finishing technology of fabric, and is especially finishing process of pure cotton elastic non-polyurethane heavy twill fabric. The finishing process includes the procedures of enzyme desizing, gas singeing, boiling off, bleaching and normal temperature clip mercerizing. The enzyme desizing procedure includes the steps of padding the grey fabric in desizing amylase liquid, stacking in disizing machine, steaming, water washing and drying; and the clip mercerizing procedure includes the steps of soaking in alkali solution, mercerizing, neutralizing, drying, post-finishing, etc. The finished fabric is environment friendly, soft, hydroscopic, permeable and comfortable, and is suitable for making men's casual clothing as well as work clothing, medical article, etc.

Description

The finishing technique of the thick and heavy twill fabric of pure cotton elastic non-polyurethane

Technical field

The present invention relates to the arrangement of textiles, refer in particular to and to make that pure-cotton fabric has elasticity, flatness is good, feel is smooth, embody the thick and heavy twill fabric finishing technique of non-polyurethane of natural stype.

Background technology

In order to make pure-cotton fabric have certain elasticity, be added with spandex on the market in the resilient pure-cotton fabric usually, but be added with the elasticity pure-cotton fabric of spandex, " tangerine peel " phenomenon, not well-pressed, poor flatness can appear in washing back lining; The pure-cotton fabric that contains spandex, it is big that the outward appearance when outward appearance and consumer are bought is experienced gap, and add spandex be furnished with fracture of wire or the bad problem that shows money or valuables one carries unintentionally a little of obvolvent, very big to spinning, the technological challenge of weaving cotton cloth, loss is easily arranged; Spandex has placement again after the problem that causes elastic fatigue for a long time, and door width of cloth gap is excessive, cause that shrinkage differs, ready-made clothes factory scalds the problem that contracts, cause the money size to differ, and if need carry out arrangement under the high temperature to lining, its powerful index is restive, and the cloth surface damage is very big, particularly for being applied to the men's clothing casual pants and seams of a trouser leg requirement is arranged, containing the spandex lining can't reach.

Summary of the invention

Purpose of the present invention is intended to overcome deficiency of the prior art, the thick and heavy twill fabric of textile non-polyurethane (annotate: every square yard of grammes per square metre is about 8 ounces) is provided, make that lining is flexible, flatness good, feel is smooth, has natural stype, be used to make men's clothing leisure clothing, be particularly useful for satisfying the demand that the seams of a trouser leg is arranged, be applicable to frock and medical use again, can significantly improve product specification and business economic benefit simultaneously.

The object of the present invention is achieved like this, and the thick and heavy grey twill of cotton textiles is padded amylase destarch working solution, and loose formula is stacked on the desizing machine, in 98 ℃-100 ℃ decatize 15-30 minute, washing, drying more than 90 ℃ keep grey cloth wrinkle resistant in the process then; The destarch Working Procedure Controlling must be got well, and is the basis that later process obtains the desirable door width of cloth.

Grey cloth after the destarch carries out gas singeing, boiling-off, bleaching process successively, frequent again stupe pincers mercerising, mercerizing process is the critical process that the control gate width of cloth shrinks, specific practice is: concentration of lye is 220-230g/l, and the cloth time of stretching tight is 60～75 seconds, and the speed of a motor vehicle is 60～70 meters/minute, warp-wise tension force suitably strengthens in the mercerising process, be 3.5～4.0kg, negative overfeeding 1～2% when rolling the laggard cloth gripper of alkali, broadwise is lax not to widen a width of cloth and makes tension force as far as possible little; Close towards sucking pump only cloth gripper spray on a small quantity, go out 80～90 ℃ of open washings of cloth gripper, last 3 lattice add acetic acid neutralization automatically, and are dry behind 2 lattice open washings again.

By control to enzyme desizing, mercerizing process, can obtain flexible thick and heavy twill fabric, product behind the mercerising is according to the requirement of using, carry out the postorder arrangement again, promptly dye its special arrangement that requires of laggard Xingqi (as preceding bake, after bake non-ironing, ready-made clothes is non-ironing, the antifouling processing of waterproof and oilproof etc.), carry out preshrunk at last.

In the production process of this product, all pursue the natural school width of cloth, under unruffled prerequisite, do not widen as far as possible, do not need independent HEAT SETTING, DIMENSIONAL STABILITY is good, both kept the environmental protection of cotton fiber nature, soft, sucting wet air permeability good, advantage such as comfortable comfortable and easy to wear, certain elasticity is arranged again, it is smooth to wash the back, and anti-chlorine floats, and can be used as to do in men's style leisure wear, particularly with the in men's style casual pants of the seams of a trouser leg, frock, medical products etc. also suit to do.

The specific embodiment

Embodiment 1, the finishing technique of the thick and heavy twill fabric of pure cotton elastic non-polyurethane:

1. enzyme desizing: the thick and heavy grey twill of cotton textiles is padded amylase destarch working solution, and loose formula is stacked on the desizing machine, in 98 ℃-100 ℃ decatize 15-30 minute, washing, drying more than 90 ℃ keep grey cloth wrinkle resistant in the process then;

The laggard promoting the circulation of qi body of enzyme desizing singe, boiling-off, bleaching process;

3. normal temperature cloth gripper mercerising, concentration of lye is 220-230g/l in the process, cloth time of stretching tight is 60～75 seconds, and the speed of a motor vehicle is 60～70 meters/minute, and warp-wise tension force is 3.5～4.0kg in the mercerising process, negative overfeeding 1～2% when rolling the laggard cloth gripper of alkali, broadwise is lax not to widen a width of cloth and makes tension force as far as possible little, close towards sucking pump only cloth gripper spray on a small quantity, go out 80～90 ℃ of open washings of cloth gripper, end 3 lattice add the acetic acid neutralization automatically, and are dry behind 2 lattice open washings again.

Under the normal condition, the door amplitude variationization is exemplified below: mercerising advances cloth 64.5 ", car 60～61 in the cloth gripper ", mercerising cropping 58～59 ".

Embodiment 2, reference example 1, carry out after the dyeing of product behind the normal temperature cloth gripper mercerising as preceding bake, after bake special postorder such as non-ironing, that ready-made clothes is non-ironing, waterproof and oilproof is antifouling and handle, carry out preshrunk at last.
