Problems solved by technology

However, there are still some deficiencies in the use of protease to treat wool
Due to the special structure of lipids and cystine disulfide bonds in the surface of wool fiber and cuticle, protease cannot degrade, and enters the interior of wool

Abstract

The invention discloses a bio-enzymatic treating method for improving anti-felting performance of wool fabric. The wool fabric is pre-treated firstly through cellulase and xylanase, so that impurities coating the wool fiber surface are removed, the purity of wool fibers is improved, and the fabric touches better; cutinase treatment is performed, so that lipoid on the wool fiber surfaces is removed, and the hydrophilicity of scale surfaces is improved. The wool fabric is soaked in a chitosan solution after being subjected to cutinase treatment, the space between scales and a cortical layer is filled with chitosan, infiltration of protase in the wool fibers is reduced, so that protase can act on surfaces of the wool fibers better, hydrolysis in the wool fibers is reduced, and the strength of the wool fibers is improved.

Description

technical field [0001] The invention relates to the field of textile auxiliaries, in particular to a wool fabric anti-felting biological enzyme treatment method. Background technique [0002] Wool has good thermal performance, good elasticity, soft touch and strong moisture absorption ability, etc., and is deeply loved by consumers. Wool is composed of scale cells, cortical cells and intercellular matrix CMC. Among them, the intercellular matrix CMC structure exists between the wool cells and is distributed in a net shape throughout the wool structure. It is a bridge connecting wool cells and plays a very important role in the mechanical strength of wool. Wool has fluffing properties, and wool fabrics will shrink when subjected to external forces in a humid and hot state, that is, wool fibers lose elasticity and curl, and the fabric shrinks. Therefore, in order to improve the use quality of wool fabrics, it is necessary to perform anti-felting finishing on them. [0003] ...
