Problems solved by technology

[0006] Although the above-mentioned patent uses pectinase to replace the traditional caustic soda high-temperature scouring process and greatly reduces the amount of caustic soda and water (cleaning), it cannot reduce the amount of fading reagents used. Fading reagents are generally corrosive to the skin and increase the amount of sewage. Discharge, pollute the environment, not conducive to environmental protection

Abstract

The invention relates to a desizing and decolorizing complex enzyme for treating natural fiber-containing fabric and a preparation method thereof. The desizing and decolorizing complex enzyme for treating the natural fiber-containing fabric is prepared from the following components in percent by weight: 30-35% of a desizing enzyme, 13-16% of ligninase, 20-26% of neutral cellulase, 26-32% of tetrasodium ethylenediaminetetraacetate, 5-8% of a nonionic surfactant and the balance of deionized water. The preparation method of the desizing and decolorizing complex enzyme for treating the natural fiber-containing fabric comprises the following steps: weighing raw materials according to the proportions in a formula, performing staged stirring and a heating reaction, and finally adding measuring powder, uniformly mixing and rotating by using an agglomeration moulding machine to obtain the granular desizing and decolorizing complex enzyme. In the process of treating the natural fiber-containingfabric by using the desizing and decolorizing complex enzyme for treating the natural fiber-containing fabric, 2-3 washing processes are reduced, water and energy can be saved by 30-50%, mechanical wear on a denim garment is reduced, strong damage is reduced and discharge of harmful substances is reduced.

Description

technical field [0001] The invention relates to the technical field of fabric auxiliaries, in particular to a desizing and decoloring compound enzyme for treating fabrics containing natural fibers and a preparation method thereof. Background technique [0002] Natural fiber fabrics refer to fabrics made of natural fibers, which are further divided into plant fibers, animal fibers and mineral fibers. Natural fibers are textile fibers obtained directly from natural or artificially cultivated plants and artificially raised animals, and are an important source of materials for the textile industry. Cotton and hemp fibers are natural plant fibers, silk and wool fibers are animal fibers, and asbestos is a natural mineral fiber. Therefore, according to the different sources of raw materials, natural fabrics can be divided into four categories: cotton fabrics, wool fabrics, silk fabrics, and hemp fabrics. In leather products, these four kinds of natural fiber fabrics can be used a...
