The invention discloses a kind of acid proteases of wool fabric to contaminate pre-treating method, including prerinse, deionized water wetting wool and hydrogen peroxide three (2- carboxyethyl) phosphonium salt hydrochlorate with bath three steps of bleaching.The acid protease dye pre-treating method of the wool fabric destroys the scale layer of wool fiber using three (2- carboxyethyl) phosphines as the reducing agent of disulfide bond, and simple with bath processing wool fiber step, thinning effect is good；With using compared with three (2- carboxyethyl) phosphines, the favorable solubility of three (2- carboxyethyl) phosphonium salt hydrochlorates, the reactivity in aqueous solution is strong, and stability is high.
Description
Technical field
The present invention relates to the refinement technology fields of fiber in wool fabric, and in particular to a kind of acidic protein of wool fabric
Enzyme contaminates pre-treating method.
Background technique
Clothes develop to lightening, comfortableization, Leisure orchards, functionalization, superior direction on the market at present.Wool textile is worn
Prodding and itching feeling and sense of discomfort be one of the main reason for influencing its use, and this is because the whole partially thick and fineness of wool fiber
It is discrete it is big caused by, and superfine wool is mainly produced in Australia, and limited amount, expensive.The scheme of replacement is to sheep
Hair carries out micronization processes, and fine wool fabric has the feel and style of similar goat cashmere fabric, can make full use of wool in this way
Resource improves the added value of wool product.
The thinning method of wool mainly distinguishes physical method and chemical method two major classes, and wherein physical method uses the side of slenderised wool
Formula carries out, main that chemical method is selected to be refined for wool fabric.Chemical method include chloridising, dioxygen water treating method,
Potassium permanganate facture, formic acid succusion, alkaline etching and Protease Treatment method.But protein decomposition enzyme be first will be easy
Hydrolyzable moiety decompose, will lead in this way fiber each section decrement it is irregular, intensity excessively declines；On the other hand, enzyme itself is molecule
Biggish protein, poor permeability are measured, and the scale layer of wool contains more disulfide bond, structure is hard, and resistance to enzymolysis ability is strong,
It needs to pre-process wool.But pretreated extent of reaction control difficulty, it is mainly shown as scale damage layer and corrodes
To the cortical layer of fiber, intensity sharply declines.
Summary of the invention
It is an object of the invention to overcome defect existing in the prior art, a kind of acid protease of wool fabric is provided
Pre-treating method is contaminated, three (2- carboxyethyl) phosphonium salt hydrochlorates are soluble easily in water, restore wool surface using three (2- carboxyethyl) phosphines
Disulfide bond, destroy fiber scale layer, with acid protease with bath processing wool fiber, thinning effect is good.
To achieve the above object, the technical solution of the present invention is as follows: a kind of acid protease of wool fabric contaminates pre-treatment side
Method, which comprises the following steps:
S1: wool is placed in prerinse in soap lye or aqueous acetone solution, drying；
S2: wool obtained by S1 is impregnated into 10~20min in deionized water, squeezes and removes excessive moisture；
S3: wool obtained by S2 is placed in the bath enzymatic treatment liquid containing three (2- carboxyethyl) phosphonium salt hydrochlorates and acid protease,
40~50 DEG C are heated to, then 2~4h of insulation reaction takes out wool, abundant cleaning, drying obtains before contaminating through acid protease
The wool fabric of processing.
Preferred technical solution is, with wool fabric poidometer, the dosage of tricarboxylic ethyl phosphine is 1.5 in a bath enzymatic treatment liquid
~4%owf.
Preferred technical solution is, with wool fabric poidometer, the dosage of acid protease is 0.8 in a bath enzymatic treatment liquid
~3% owf.
Preferred technical solution is that the pH value of a bath enzymatic treatment liquid is 5~6.
Preferred technical solution is also to contain alkaline pH adjuster in a bath enzymatic treatment liquid, alkaline pH adjuster is
Combination selected from one or more of sodium phosphate, disodium-hydrogen, sodium acetate and sodium hydroxide.
The advantages and beneficial effects of the present invention are:
The acid protease dye pre-treating method of the wool fabric is broken as the reducing agent of disulfide bond using three (2- carboxyethyl) phosphines
The scale layer of bad wool fiber, simple with bath processing wool fiber step, thinning effect is good；
With using compared with three (2- carboxyethyl) phosphines, the favorable solubility of three (2- carboxyethyl) phosphonium salt hydrochlorates, the reaction in aqueous solution
Active strong, stability is high.
