Problems solved by technology

When cellulase is used in biopolishing, it is necessary to remove hair cleanly and feel good, and to minimize the weight loss and strong damage to the fabric. Since traditional cellulase is unknown to its components and the content of each component, usually It is difficult to meet the above requirements at the same time
[0009] At present, the bio-polishing cellulase products for fabrics on the market, some have clean hair removal, and some have good color retention, but it is difficult to do little damage to the fabric at the same time

Abstract

The invention discloses a liquid biological polishing enzyme and a preparation method thereof. The liquid biological polishing enzyme contains the following components: 30000-40000mu / mL of beta-1, 4-exoglucanase, 20000-30000mu / mL of beta-1, 4-hydrolytic endoglucanase, 4000-5000mu / mL of beta-glucosaccharase and deionized water. The pH value of the liquid biological polishing enzyme is 4.7-5.2, and the total activity of the enzymes is 1000-2000mu / mL. The liquid biological polishing enzyme has the advantages of obvious biological polishing effect and low loss ratio and generates small damage to fabrics.

Description

technical field [0001] The invention relates to cellulase, in particular to a liquid bio-polishing enzyme used in the textile industry and a manufacturing method thereof. Background technique [0002] It is well known that the structure of natural cellulose fibers is complex, the degree of crystallinity is high, and the molecular system of cellulase is relatively large, so it cannot penetrate into the crystallization area to decompose all the fibers into glucose. However, after the fiber is treated with cellulase, the physical properties of the fiber will change, the transverse fracture, the strength will be reduced, the degree of polymerization will be reduced, the moisture absorption capacity and alkali resistance will be increased, and the fiber will be cracked into short and detachable fiber fragments. According to this principle, the controlled cellulase treatment of textiles can make the fabrics have a long-lasting smooth surface, clear texture, soft hand feel, improve...
