Method for Improving Strength and Dyeing of Wool Fibers

Abstract

The disclosure provides a method for improving the strength and dyeing of wool fibers, and belongs to the technical field of modification of textile materials. By using the feature that protein fiber macromolecules contain a large number of active groups such as hydroxyl groups, amino groups and carboxyl groups, which easily react with polyphenolic pigments formed by a phenolic compound catalyzed by an enzyme to form covalent bonding, the disclosure realizes low temperature dyeing of wool fibers while improving the fiber strength. The disclosure has mild operating conditions easy to control, and in view of increasingly emphasis on environmental protection nowadays, the use of the biological enzyme for dyeing wool fibers is safe, environmentally friendly and efficient, and has a long-term development prospect.
