Problems solved by technology

In the prior art, the above phenomenon can be avoided by selecting the hydrogen peroxide oxidation method, but the hydrogen peroxide oxidation method will inevitably cause damage to the surface of the wool fiber
[0003] The air layer fabric is generally composed of the surface layer fabric and the air layer auxiliary materials. In order to ensure the novel pattern of the air layer fabric, digital printing is often used in the prior art. However, the yellowing of the wool fabric after mercerizing treatment is large. In order to achieve a colorful pattern Purpose, it is necessary to increase the bleaching steps, increase the production process, and the operation is cumbersome. Bleaching will further damage the fibers and cause the strength of the fabric to decrease. Therefore, it is necessary to improve the mercerizing process of the surface fabric of the air layer fabric

Abstract

The invention discloses a preparation method of mercerized wool air-layer composite fabric. The preparation method comprises the following steps: chlorination, enzymatic reduction, enzymatic hydrolysis, softening, bonding compounding, digital-printing and the like. According to the chlorine enzymic mercerization technology, a substrate lysine and a catalyst horseradish peroxidase which can rapidly react with wool color-developing lysine residues are added into a treating fluid during the reduction step. By the characteristic of fast enzymatic reaction rate, residual chlorine obtained after chlorination scale-stripping is prevented from undergoing an oxidation reaction with tyrosine residues on the wool surface. By applying the above mercerized wool in production of air-layer fabric, it is guaranteed that yellowing of the mercerized wool layer is small and the fabric obtained after digital printing has bright color. According to the invention, reaction process is not increased, and yellowing protection and free chlorine reduction are combined. The preparation method has simple steps and is convenient to operate.

Description

technical field [0001] The invention relates to the technical field of fabrics, in particular to a method for preparing a mercerized wool air layer composite fabric. Background technique [0002] The scale layer is a unique structure of wool fiber, which makes wool have special luster and milling performance, but also leads to difficulty in dyeing wool, poor shape stability when washing and itching when wearing. The squamous layer is composed of keratinized flat cells through a cell membrane complex. The principle of mercerizing wool is to use appropriate physical and chemical methods to soften and degrade the scales of wool, so that the scales of wool are damaged and partially or completely peeled off, so as to improve the surface shape of wool fibers and make them feel like cashmere. with gloss. The physical method in the prior art includes the resin increment method, and the chemical method is commonly used the thinning and decrementing method. At present, the commonly...
