Abstract

The invention relates to a nursing and felt proofing finishing method for wool fabric with ultraviolet radiation based on keratin oligopeptides, polypeptides or keratin macro-molecules. A biochemicalmethod is used for extracting keratin oligopeptides, polypeptides or keratin macro-molecules from animal fibre, and a heterogenous protein cross-linking agent is used for carrying out a reaction in order to prepare reaction type keratin finishing liquid; the liquid is applied on wool fabric by sprinkling and dipping; after the fabric is dehydrated and spin-dried, and ultraviolet radiation and nature drying are carried out in order to realize an application of keratin oligopeptides, polypeptides or keratin macro-molecules to nursing and felt proofing finishing of wool fabric. The finishing process is simple and easy to operate with low energy consumption and little pollution, and does not have obvious influences on appearance of the wool fabric; the wool fabric treated by the nursing and felt proofing finishing method has good size stability, crease recovery performance, and improved breaking strength and elasticity.

Description

technical field [0001] The invention relates to the technical field of fiber treatment and finishing, in particular to a method for realizing care and anti-felting finishing of wool fabrics by using modified keratin oligopeptides, polypeptides or macromolecular finishing solutions extracted from protein fibers through ultraviolet irradiation. Background technique [0002] Wool fiber has many excellent properties unmatched by other fibers, such as good elasticity, good warmth retention, soft luster and rich hand feeling, and is favored by consumers. However, due to its complex fiber structure, it is prone to problems such as felting and dimensional changes and damage during daily dressing and washing. [0003] At present, it has been reported that keratin is used in the anti-felting finishing of wool fabrics, mainly by using oxidant method, reduction method, cuproammonia solution method and other chemical preparations to obtain keratin macromolecules with poor water solubilit...
