Oxidation and keratin cashmere after-finishing liquid and finishing method

Abstract

The invention discloses an oxidation and keratin cashmere after-finishing liquid and a finishing method. The cashmere after-finishing liquid (oxidation liquid) comprises sodium percarbonate, TAED, an oxygen bleaching stabilizer and the balance of water. The cashmere after-finishing liquid (keratin liquid) comprises keratin and the balance of water. According to the finishing method, the cashmere fabric is subjected to low-temperature oxidation treatment through sodium percarbonate, so that a scale layer of fibers is thinned, surface hairiness is effectively removed, the directional friction effect is reduced, and the anti-pilling performance can be improved; and after keratin treatment, keratin is attached to the surfaces of the fibers, crosslinking is achieved in protein peptide chains, a formed keratin film is coated on the surface of the fiber to ensure that the color difference and the hand feeling of the cashmere fabric are basically unchanged, and the anti-pilling performance of the cashmere fabric subjected to oxidation and keratin finishing is improved by one level or above compared with the original level.

Description

technical field [0001] The invention relates to the technical field of textile production, in particular to an oxidation + keratin cashmere finishing liquid and a finishing method. Background technique [0002] Cashmere is a high-grade natural fiber with fine fineness, good hygroscopicity, and soft and natural luster. Its cashmere garments are soft to the touch, full of suede, and good in warmth retention. They have always been one of people's favorite fashion garments in winter. [0003] Cashmere fibers are short in length, less crimped, and poor in cohesion between fibers. The fibers are easy to slip off from the yarn and fluff up. With the increase of wearing and washing friction times, they are not easy to be broken and easily entangled 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 ...

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
