Abstract

The invention relates to a multifunctional modification processing method for wool, which comprises the following steps: soaking the wool into finishing liquor containing chitosan guanidine hydrochloride, polycarboxylic acid and sodium hypophosphite for 5-30 minutes and soaking and rolling twice, wherein the rolling residual rate is 80-120 percent; then drying at 80 DEG C for 5 minutes; baking at120-160 DEG C for 3-5 minutes; fully washing by hot water at 50 DEG C and washing by cold water; and finally drying. The invention has simple process and energy source saving, reduces or prevents environmental pollution and is suitable for industrialized production; and modified wool fabrics have favorable antibacterial performance, hygroscopicity and wrinkle resistance and can greatly improve thedyeing performance of active dye and acid dye for the wool on the wool fabrics after being processed.

Description

technical field [0001] The invention belongs to the field of wool modification treatment, in particular to a multifunctional modification treatment method of wool. Background technique [0002] As a natural fiber, wool is soft to the touch, full of elasticity, natural and soft in luster, and firm in texture. It is deeply loved by consumers and is called the "soft gold" of wool. It is suitable for all kinds of high-end underwear and outerwear, and is deeply loved by consumers, but it also has many unsatisfactory places, such as easy to breed bacteria and poor hygroscopicity. In addition, due to the existence of scales on the surface of the fiber, traditional dyeing must be done before boiling. It is easy to cause damage to wool fibers. At present, people are looking for various ways to modify wool to improve its shortcomings, among which chitosan as a green and pollution-free modifier has attracted widespread attention and research. [0003] In textile dyeing and finishing,...
