Abstract

The invention discloses a bio-enzyme felt proofing technology of a knitted woolen sweater. The technology comprises the following steps of: carrying out a pre-processing technology by using sodium pyrophosphate, peregal and hydrogen peroxide; carrying out protease processing by using an activating agent and peregal, and inactivating by using glacial acetic acid; and processing a fabric by using a softening agent, centrifugally dewatering, and drying. Compared with the conventional bio-enzyme felt proofing technology for the knitted woolen sweater, the technology disclosed by the invention is good in felt proofing effect and is capable of improving the vividness of colorful fabric by combination of he proper preprocessing, the reasonable bio-enzyme processing and softening technology.

Description

The biology enzyme feld proofing technique of knitting woollen sweater
Technical field
The invention belongs to the textile dyeing and finishing technical field, relate to the feld proofing technique of woollen sweater, be specifically related to a kind of biology enzyme feld proofing technique of knitting woollen sweater.
Background technology
Raising along with people's living standard, also day by day increase taking the comfortable demand of being convenient to again the wool fabric that washs, overcoming wool fabric easy research that serious felting occurs in water-washing process becomes the important topic of industry, require wool fabric should keep original high-grade quality, haveing breakthrough aspect wearability and profile maintenance, namely accomplish " machine washable " again.Therefore, how to solve " machine washable " problem of wool fabric, become professional's problem in the urgent need to address.Have at present the whole bag of tricks to improve the defective of wool fabric, more use be chlorination-resin method.Though this method has advantages of that anti-felting effect is good, yet have the absorbable organohalogen compounds of a large amount of AOX(in technique waste water) the class material, big for environment pollution, be eliminated at last.Utilize cellulase treatment to become the main direction of felt proofing technological development, also more and more be used in the rear arrangement of wool fabric.
The biological enzyme of wool is processed and is belonged to chemical subtraction process, and the effect of enzyme is to add the catalyst of water decomposition as peptide chain.Wool is put into the protein enzyme solution of certain bath raio, enzyme is played a role, enter fibrous inside from the hydrophilic segment of wool surface scale layer, impel the amido link hydrolysis in wool, this hydrolysis is a heterogeneous catalytic reaction, at first wool surfaces attracts each other with the surface of enzyme medium, then diffuse into fibrous inside, biocatalytic reaction progressively occurs, wool is through secondary response, and surperficial scale is destroyed, and even comes off, reduce along the difference against coefficient of friction with this, thereby improve anti-felting, anti-pilling property.General cellulase treatment does not also reach desirable anti-felting effect, and the processing such as resin or gel of also will adopting that have just can reach the effect of felt proofing, and this not only increases cost, also can affect the style of fabric.
Summary of the invention
The invention provides a kind of biology enzyme feld proofing technique of knitting woollen sweater newly, to improve the anti-felting effect of woollen sweater.
The biology enzyme feld proofing technique of knitting woollen sweater of the present invention comprises the steps:

3, soft finish technique
Under the condition of 40 ℃-45 ℃ of temperature, bath raio 1: 15-20, fabric is processed 10min-30min, centrifugal dehydration, 70 ℃ of-90 ℃ of oven dry with 1%-10% (owf) softener.
Preferably, described sodium pyrophosphate concentration is 4g/L during the hydrogen peroxide pretreating process.
Preferably, described concentration of sodium carbonate is 2.5wt% during the hydrogen peroxide pretreating process.
Preferably, described H during the hydrogen peroxide pretreating process 2O 2Concentration is 25g/L.
Preferably, described protease consumption is 2.5owf% during enzyme treatment process.
During preferably, soft finish technique, described softener consumption is 5owf%.
Compare with the biology enzyme feld proofing technique of traditional knitting woollen sweater, technique of the present invention is by adopting suitable preliminary treatment, in conjunction with rational cellulase treatment and soft technique, not only reached good anti-felting effect, and improved the vividness of colored fabric.
