Technique for preventing wool loomage from felting by two-bath process using cutinase/protease

Abstract

The invention discloses a method for performing an anti-felting process of a wool fabric by a two-bath process by applying cutinase / prolease, which belongs to the technical field of dye and finishing processing of wool fabric. The method aims to overcome the defects that the felt proofing by a wool chlorination method has serious environmental pollution and fabric treated by a single prolease method has poor wettability and high felting shrinkage and achieve the aim of optimizing the treatment effect of the prolease of the wool fabric. All wool grey cloth is extracted and removed with free oil impurities in a carbon tetrachloride / methanol solution first, is presoaked by hot water, then is treated in a cutinase solution, is removed with lipoid layer hydrolysates of scale surface layers through the extraction of carbon tetrachloride / methanol, and then is subjected to decrement processing in a prolease solution to realize the biological processing combined with enzymatic pretreatment andenzyme decrement of wool. Through the invention, a method combined with chemistry and the prolease is substituted by a wool shrinkproofing process by a complete biological method, which not only can effectively improve the decrement rate and the antifelting effect of the wool fabric, promote the improvement of the wettability of the fabric, but also can effectively improve the dyeing depth of thefabric, reduce the fiber damage in the decrement processing, and is also favorable for the protection of ecological environment.

Description

A kind of application cutinase / protease to carry out two-bath method wool fabric anti-felting process method technical field The invention discloses a two-bath wool fabric anti-felting process method using cutinase / protease, which belongs to the application technical field of wool fabric dyeing and finishing in the wool spinning industry. Background technique Wool has fluffing properties. When the wool fabric is subjected to external force in a humid and hot state, it will produce felting, shrinking the area, changing the shape, protruding fluff, reducing elasticity, rough hand feeling, and seriously affecting the appearance and wearing performance of the fabric. Therefore, it is necessary to carry out weight reduction and anti-felting finishing for the purpose of removing the scale layer on the woolen fabric. At present, the anti-felting effect of wool is better and the most widely used is the chlorination method, such as hypochlorite or dichloroisocyanurate (DCCA) for tr...
