Continuous processing technology for non-shrink treatment of chlorine-free wool top and wool product

Abstract

The invention relates to a continuous processing technology for non-shrink treatment of chlorine-free wool tops and wool products. The continuous processing technology comprises the following steps: non-shrink treatment, washing, inactivation of protease, softening, dehydration, and drying. On the basis of the characteristic that wool fiber is protein fiber, the processing technology employs a high-efficiency integrated catalysis system composed of protease, a water-soluble aliphatic tri-substituted organic phosphine structured activator, a metal salt and a nonionic surfactant to efficiently and partially remove scales on the surface of the wool fiber so as to realize modification of the scales; thus, the felting performance of wool products is improved, dimensional stability of wool products is enhanced, and the requirement for machine washability is met. The continuous processing technology provided by the invention can replace chlorination anti-shrinkage methods in the prior art, avoids environmental pollution caused by the chlorination methods and is a clean treatment process according with environmental requirements. The continuous processing technology is small in usage amounts of reagents, low in cost, simple in process, low requirements on equipment and capable of realizing continuous operation and industrial production.

Description

technical field

[0001] The invention relates to a method for finishing wool tops and wool products in the textile field, in particular to a continuous processing technology for shrink-proof treatment of chlorine-free wool tops and wool products. Background technique

[0002] Wool is an important raw material for the textile industry. It has many excellent properties, such as good elasticity, strong hygroscopicity, not easy to stain, good warmth retention, and soft luster. Wool is a natural protein fiber with a layer of overlapping fish scales mainly composed of keratin on its surface. Due to the different friction coefficients in the forward and reverse directions of the scales, the wool fibers will intersect each other under repeated external forces. , entanglement, interweaving, and felting to produce fluffing. Although milling makes the wool fabric have beautiful appearance, rich and soft hand feeling, and good thermal performance, it also makes the wool fabric prone to ...
