Biopolishing enzyme

Biological enzymes were only used for fabric desizing in the textile industry a long time ago, and amylase was used to catalyze the hydrolysis of starch sizing on fabrics. In the current production process, this is still an important method to remove starch slurry, but now there is high temperature-resistant amylase, which can not only improve the desizing efficiency, but also remove PVA in the mixed slurry at the same time. chemical slurry.
In addition, another area of ​​biological enzymes in the textile industry is the finishing of cotton fabrics. After the cotton fabric is treated with cellulase, the hand and appearance can be greatly improved. Since the fluff on the surface of the cotton fabric is removed, the fabric is smoother and the color is brighter. The study by LeeG.Snyder et al. confirmed that cellulose can make the appearance of knitted fabrics become smooth, and the cellulose added in washing powder can also have a similar effect through normal domestic washing machine washing. C.Lchong et al also studied the effect of cellulase dosage, friction between fabrics and mechanical agitation on the finishing properties of fabrics. All these studies are widely used in denim finishing today. Most denim garments have to go through the washing and grinding process to make them look old. In the traditional stone washing process, the pumice stone is polished to remove some dyes to lighten the color of the denim. Good results can be achieved, making it have the advantages of better appearance, lower price, shorter processing time and less solid residue.
