A cashmere finishing liquid and finishing method of oxidation + keratin

Abstract

The invention discloses an oxidation + keratin cashmere finishing solution and a finishing method. The composition of the cashmere finishing (oxidizing solution) includes sodium percarbonate, TAED, an oxygen bleaching stabilizer, and remaining water; the cashmere finishing (keratin The composition of liquid) includes keratin and the remaining water; the finishing method is to oxidize the cashmere fabric with sodium percarbonate at low temperature first, so that the scale layer of the fiber is thinned, and the surface hairiness is effectively removed, thereby reducing the directional friction effect and improving the anti-friction effect. After the treatment of keratin, the keratin is attached to the surface of the fiber and cross-linked in the protein peptide chain, and the formed keratin film is coated on the surface of the fiber to ensure that the color difference and hand feel of the cashmere fabric are basically unchanged. Change, the anti-pilling performance of the cashmere fabric after oxidation + keratin is improved by more than 1 grade compared with the original grade.

Description

technical field [0001] The invention relates to the technical field of textile production, in particular to an oxidized + keratin cashmere finishing solution and a finishing method. Background technique [0002] Cashmere is a high-grade natural fiber with fine fineness, good hygroscopicity, soft and natural luster. Its products are soft to the touch, plump in suede and good in warmth retention. It has always been one of people's favorite fashion clothing in winter. [0003] Cashmere fibers are short in length, less crimp, and poor in cohesion between fibers. The fibers are easy to slip from the yarn and fluff. With the increase of wearing and washing friction times, it is not easy to wear off and easily tangle into balls, which affects its wearing performance and appearance. . [0004] In the prior art, anti-pilling finishing methods are mainly divided into three categories: the first category is to use physical or chemical methods to destroy the scale layer of cashmere fib...

Problems solved by technology

[0006] In the "subtractive" finishing, the chlorination method has been basically eliminated due to environmental protection reasons; the oxidation method, protease method and low-temperature plasma method are mainly aimed at the research and application of wool fabrics in the early stage, which will cause great damage to cashmere fibers and have a great impact on the hand feel, so they are not suitable. For single application, among them, the capital investment of low temperature plasma method equipment is large, which affects the production cost

[0007] In the "additive" finishing, the sol-gel method, resin method, sericin method and chitosan method can improve the anti-pilling performance, but the hand feeling is generally hard or unreal, and the color is affected, and the suede is soft but poor. Not plump, reducing the original style characteristics of cashmere

[0008] In the "combined method" finishing, reducing agent + keratin, resin finishing + softener, protease + protective agent, chitosan + resin, protease + silk fibroin, protease + resin, low temperature plasma + protease, protease + permanganate Potassium, hydrogen peroxide + protease, cutinase + protease and other methods have certain effects on improving the anti-pilling performance of cashmere fabrics, but it is difficult to reflect the soft and full cashmere characteristics of cashmere, and at the same time, the color difference still has a certain effect
