Problems solved by technology

However, due to the small size of the protease molecule, protease can penetrate into the cortex layer inside the wool fiber from the scale gap on the surface of the wool fiber, thereby causing damage to the internal structure of the fiber, resulting in a decrease in the breaking strength of the wool fabric

Abstract

The invention relates to the technical field of wool fabrics, and discloses a wool fabric felt proofing finishing technology. The technology includes the following steps that S1, the wool fabrics areput into oxidation treating fluid for oxidation treatment, so that pretreated wool fabrics are obtained; S2, compound protease is added into a Tris-HCl buffer solution for ultrasonic oscillating dispersion, so that compound protease dispersion liquid is obtained, the pretreated wool fabrics are put into the compound protease dispersion liquid for enzymolysis, and enzyme-dispersed wool fabrics areobtained; and S3, sodium hydroxide is added into a polyvinyl acetate solution, alcoholysis liquid is obtained by means of stirring alcoholysis, the enzyme-dispersed wool fabrics obtained in the S2 areput into the alcoholysis liquid for soaking and then are put into a glutaraldehyde solution for carrying out a cross-linking reaction after being taken out, and then the wool fabrics are obtained through alcohol washing and drying. The wool fabrics prepared through the technology can keep high breaking strength after being finished by enzymolysis liquid, and the felt proofing performance is good.

Description

technical field [0001] The invention relates to the technical field of wool fabrics, in particular to an anti-felting finishing process of wool fabrics. Background technique [0002] Wool fabric has many excellent properties, such as good elasticity, strong moisture absorption, good warmth retention, and soft luster. Wool fabric is deeply loved by consumers for its noble style and elegant wearing performance. Wool fiber is mainly composed of the scale layer covering the outside of the fiber, the cortex layer that constitutes the main part of the wool entity, the medulla layer in the fiber center that is opaque due to air content, and the scale inner layer. The wool scale layer contains a large number of disulfide bonds. The structure is compact, which can protect the inner layer of wool and resist the erosion of external machinery and chemicals. The structure of the wool scale layer makes the wool fiber prone to felt shrinkage after being continuously squeezed and rubbed du...
