Description
Technical field
The present invention relates to a kind of fabric pretreatment method, particularly relate to a kind of Bio-enzyme pretreatment method of vinylon-cotton blend fabric.
Background technology
In weave dyeing and finishing technique, take yarn as the fabric of warp, before weaving, all have to pass through starching process, to improve the brute force of warp thread, ABRASION RESISTANCE and smooth degree, thus reduce warp end break, ensureing weaves cotton cloth carries out smoothly.Warp sizing oar material used has natural slurry as starch, wild starch, and chemical sizwe is as polyvinyl alcohol (PVA), polyacrylic acid (PAA), and cellulose preparation is as carboxymethyl cellulose (CMC) etc.Other composition is also added as preservative agent, softener, hygroscopic agent, anti-friction composition etc. in sizing liquor.The height of warp sizing rate and the quality of fiber, yarn count, density etc. are relevant, the fabric that yarn count is thin, density is large, and warp sizing rate is high, the general fabrics rate of sizing 4% ~ 8%.
Grey cloth spreading mass is unfavorable to dyeing and printing process, because the existence of slurry can stain dyeing and finishing working solution, expends dye material, even can hinder the contact of dye material and fiber, affect the quality of dyeing and printing products.Therefore, fabric just has to pass through destarch process at the beginning of dyeing and finishing processing, removes grey cloth spreading mass as much as possible.Destarch requires different and different according to the kind of following process, such as dyeing, the fabric of stamp, destarch requires higher, and requiring the destarch of BLEACHED FABRIC then can be slightly lower.
Warp thread institute spreading mass kind is relevant with the fiber species that fabric uses, and starch slurry is used for cellulose base fiber fabric, and as COTTON FABRIC, linen etc., chemical sizwe is used for closing fine fabric.Sometimes also mixed slurry starching is used.Destarch carries out destarch under desizing agent and certain effect condition.
Fabric is after kiering, and on fabric, the natural and artificial impurity of major part removes, and capillary effect significantly improves, and can meet the processing request of some kinds.But to light figured cloth, the painting cloth class of BLEACHED FABRIC and lovely luster, also need to improve whiteness, therefore need to remove the pigment on fabric further, make fabric pure whiter.Though fabric is through kiering besides, especially normal pressure decatize kiering, still have partial impurities such as cotton seed hulls to fail entirely to remove, by the effect of bleaching agent, these impurity can remove completely.
Cotton dyeing factory widely uses the oxidative bleaches such as hypochlorite, hydrogen peroxide.To cotton and cotton fabric bleaching, peracid compound as perboric acid receive, peracetic acid, sodium percarbonate etc. are also even application, sodium chlorite is used for the bleaching of synthetic fiber and BLENDED FABRIC thereof.Usually floated referred to as chlorine by hypochlorite bleaching, hydrogen peroxide bleaching is referred to as oxygen bleaching, and chlorite bleaching floats referred to as Asia.
(1) hypochlorite bleaching
Conventional hypochlorite has bleaching powder and clorox two kinds.Bleaching powder is that chlorine and calcium hydroxide effect form, and if logical chlorine is in milk of lime, can obtain the bleaching powder doubled containing active ingredient; Logical chlorine in soda bath, then can obtain clorox.In bleaching powder and bleaching powder, active ingredient is calcium hypochlorite, and total effect is not as clorox.Cotton dyeing factory larger is at present normal oneself manufactures clorox, or buys clorox for bleaching to neighbouring chemical plant, and bleaching powder is difficult to obtain the small-sized printing and dyeing mill in area of clorox for small city or rural area.Bleaching powder price is more expensive, uses less.
Sodium hypochlorite bleaching technology and equipment is comparatively simple, is used for COTTON FABRIC and victoria blended spinning fabric bleaching, sometimes also bleaches for polyester cotton.But the bleaching of the protein fibre such as silk, wool can not be used for, because clorox has destruction to protein fibre, and make fiber yellowing.
(2) hydrogen peroxide bleaching
Hydrogen peroxide also claims hydrogen peroxide.Better with the fabric whiteness of hydrogen peroxide bleaching, pure color light, not easily yellowing during storage, is widely used in the bleaching of cotton fabric.Oxygen bleaching has larger adaptability than chlorine drift.
(3) chlorite bleaching
The great advantage that sodium chlorate is used for when COTTON FABRIC is bleached is under the condition not damaging fiber, can destroy pigment and impurity.Sodium chlorite is again the good bleaching agent of chemical fibre, the retention of whiteness of BLEACHED FABRIC is better than the fabric of chlorine drift and oxygen bleaching, but sodium chlorite price is more expensive, strong to metal protection, need by titanium or titanium alloy etc materials, and producing poisonous ClO2 gas in sub-drift process, equipment need have good sealing, therefore in use, is subject to a definite limitation.
Existing fabric pretreatment, generally includes above-mentioned destarch and blanching step, and each step is consuming time longer, and energy consumption is larger.
Summary of the invention
For the deficiencies in the prior art, technical problem to be solved by this invention is to provide a kind of Bio-enzyme pretreatment method of vinylon-cotton blend fabric, and destarch and blanching step one step complete.
