Problems solved by technology

By finishing the chitosan silica sol finishing solution on the surface of the wool fabric, the components in the finishing solution undergo a condensation reaction, and form a rigid film on the surface of the wool fabric through crosslinking, so that the wool fabric has a one-sided resistance. However, during the washing process of wool fabric, the wool fabric is subject to friction and external force, which will easily cause the chitosan layer on the surface of the wool fiber to fall off, resulting in a decrease in the anti-felting performance of the wool fabric.

Abstract

The invention relates to the technical field of wool fabrics, and discloses a durable anti-felting finishing method of a wool fabric. The method comprises the following steps of 1) placing a wool fabric in a plasma treatment instrument for plasma pretreatment to obtain a wool fabric a; 2) putting the wool fabric a into a tetrabutyl titanate solution, then dropwise adding the mixed solution into the tetrabutyl titanate solution, and putting the wool fabric in a drying oven for drying treatment to obtain a wool fabric b; 3) adding protease into water, uniformly stirring to obtain a protease finishing solution, soaking the wool fabric b in the protease finishing solution, and drying the wool fabric in a drying oven to obtain a wool fabric c; and 4) soaking the wool fabric c in a trimesoyl chloride solution at first, then putting the wool fabric c in a polyethyleneimine solution for reaction, and drying the wool fabric in a drying oven to obtain. The anti-felting wool fabric has excellentanti-felting performance and felting durability.

Description

technical field [0001] The invention relates to the technical field of fabric fabrics, in particular to a long-lasting anti-felting finishing method for wool fabrics. Background technique [0002] As a widely used natural fiber, wool has incomparable advantages over other fibers, such as soft surface luster, good elasticity, strong thermal insulation performance, wear resistance, antifouling and good moisture absorption performance. At the same time, the source of wool is extensive, and the price of wool fabric is moderate, which is deeply loved by consumers. However, the felting property of wool fabric makes wool fabric easy to feel and shrink when washed with water. After washing, the fabric will shrink, become thicker, and feel rough, which has a great impact on the style and appearance of wool fabric. A wool fabric without anti-shrinkage treatment, after a period of washing, its shrinkage rate is as high as 30-50%, which is far from the area felt shrinkage rate of no mo...
