Abstract
The invention discloses a low-temperature bleaching method of pure cotton or cotton-containing fabric. The method comprises the steps of adding 1-4g/L of a bleach activator, 3-10g/L of hydrogen peroxide, 2-6g/L of a bleaching stabilizing agent and 0.5-5g/L of a pH regulator into a bleaching system; putting the unbleached pure cotton or cotton-containing fabric into a dye bath according to the bath ratio of 1: (10-100), heating up to 30-70 DEG C at the speed of 0.5-3 DEG C/ minute, carrying out heat preservation for 20-90 minutes, finally, washing the bleached fabric with water, and drying or airing. The novel acyloxy bleach activator is added into a breaching system of the pure cotton or cotton-containing fabric, so that the breaching system can be implemented at a low temperature, and the bleaching effect of an oxidizing agent is improved; compared with the traditional oxygen bleaching system, the method is capable of reducing the damage to the fabric while improving the whiteness of the fabric.
Description
Technical field
The invention belongs to dyeing and finishing technique field, relate to a kind of cold bleaching method of cotton textiles or cotton-containing fabrics, this oxidation bleaching method is applicable to cotton textiles and the cold bleaching containing cotton blended fabric.
Background technology
Cotton fiber is most important natural textile raw material, and cotton fiber has good water absorption, and wearability is excellent, and be easy to the advantage dyeed, its market share occupies 50% of whole fiber total quantity consumed.But containing natural yellow impurity in natural cotton fiber, its pigment is mainly derived from some compounds containing chromophoric group, reduces the white appearance that cotton fiber is intrinsic.In addition the COTTON FABRIC of relaxed state is also easily subject to processing the pollution of lubricating oil in process, and these impurity need to remove in bleaching process usually, and the whiteness that providing cotton fabric is desirable, removes partial impurities simultaneously, improves water imbibition.Hydrogen peroxide (H
2o
2) be the most popular oxidative bleaches of COTTON FABRIC industrial bleaching, hydroperoxy-root anion (HO in bleaching process
2 -) play main discoloration.Hydrogen peroxide bleaching is a kind of non-environmental-pollution, energy-efficient method for bleaching simultaneously, but hydrogen peroxide is difficult to play discoloration under low temperature, low pH condition, usual needs carry out under the condition of higher temperature (closely seething with excitement), alkalescence (pH>11) and long time treatment, bleaching action condition is violent, energy consumption, time-consuming and can major injury fiber.Under realizing in current environmental protection and energy saving the situation strengthened gradually, manage to reduce bleaching temperature, improve bleaching efficiency, reducing energy consumption and production cost, is the development trend of hydrogen peroxide bleaching.
Developed both at home and abroad the hydrogen peroxide bleaching activator of multiple different structure, the most frequently used at present have alkanoyl class activator, alkoxy acyl class activator and cationic N-acyl caprolactam class activator etc.Alkanoyl class activator, its representative kind is tetra acetyl ethylene diamine (TAED), but it is water-soluble not high, slightly smell, and effective temperature is greater than 70 DEG C, and hydrogen peroxide/TAED activation system is not high lower than bleaching efficiency when 70 DEG C in temperature; Alkoxy acyl class activator, its representative kind is nonanoyloxybenzene sulfonate (NOBS), but NOBS needs (pH>10) application in the basic conditions, and most dependence on import, expensive, and in preparation process, mostly adopt organic solvent as toluene, acetone, alkane etc., do not meet ecological requirements; Cationic N-acyl caprolactam class activator; its representative kind is N-4 (triethyl ammonium methylene benzoyl group) caprolactam chloride (TBCC) and N-4 (triethyl ammonium methylene benzoyl group) butyrolactam chloride (TBBC); but it is unstable in the solution; so that can not deposit by solution state; can only deposit with solid-state; dissolving before use; this strongly limits its application in industry; and its synthesis cost is high; complex manufacturing, is only in conceptual phase at present.
Summary of the invention
The object of the invention is to overcome current cotton textiles and containing in cotton blended fabric bleaching process; conventional oxidation agent bleaching action condition is violent; serious to fibre damage; bleaching efficiency is not high, and power consumption is large, and cost is high; and there is dissolubility difficulty in most Low Temperature Bleaching Activator, environmental protection index is difficult to problem up to standard; there is provided one comparatively gentle method for bleaching efficiently, thus it is injury-free to reach protection fiber, the object of economize energy.
For achieving the above object, the present invention adopts following technical scheme: a kind of cold bleaching method of cotton textiles or cotton-containing fabrics, and improve COTTON FABRIC oxidation bleaching condition with activator, step is as follows:
Bleach-activating 1 ~ 4g/L is added in bleach system, hydrogen peroxide 3 ~ 10g/L, bleaching stibilizer 2 ~ 6g/L, acid-base modifier 0.5 ~ 5g/L, to not bleach cotton or cotton-containing fabrics fabric drops in dye bath by bath raio 1:10 ~ 100, be warming up to 30 ~ 70 DEG C with the programming rate of 0.5 ~ 3 DEG C/min, insulation 20 ~ 90min, finally washes BLEACHED FABRIC, dries or dry.
The structure of described bleach-activating is as follows:
In formula, R is COONa, COOK, SO
3na, SO
3the one of K, m=1 ~ 14, n=1 ~ 9;
Described bleaching stibilizer is one or more mixtures of sodium metasilicate, phytic acid, sodium phytate.
Described acid-base modifier is one or more mixtures in sodium carbonate, sodium bicarbonate, NaOH, sodium acetate, natrium citricum.
Cotton or cotton-containing fabrics will do not bleached to put into described in 1 in used bleach residue, and add hydrogen peroxide 1 ~ 4g/L, fabric can be made again to obtain good bleaching effect.
Beneficial effect of the present invention: the present invention adds the novel bleach-activating of acyl-oxygen base class in cotton or cotton-containing fabrics bleach system, bleach system can be implemented under cryogenic, improve oxidant bleach effect, compared with traditional oxygen bleaching system, while improving fabric whiteness, reduce fabric damage.
