Abstract

The invention discloses a scouring agent for a cotton textile. The scouring agent is prepared from the following components in parts by weight: 0.7 to 1.3 parts of immobilized enzyme, 0.6 to 1.3 parts of sodium hydroxide, 3 to 6 parts of water-soluble chitosan, 5 to 8 parts of hydrogen peroxide, 1 to 2 parts of alkyl glycoside, 0.8 to 1.5 parts of sodium silicate, 1 to 3 parts of dodecyl ethoxy sulfonyl betaine, 0.5 to 0.9 part of cocamidopropyl dimethylamine oxide, and 50 to 80 parts of deionized water. The invention also discloses a preparation method of the immobilized enzyme. The scouring agent prepared by the invention is good in scouring effect, excellent in stability, free from damaging fabrics and low in cost.

Description

Technical field: [0001] The invention relates to the field of textile auxiliary agents, in particular to a scouring agent for cotton textiles. Background technique: [0002] Before dyeing and printing, textiles need to go through a certain scouring process to remove impurities and oil stains on the cloth surface. This scouring process is often called scouring. All kinds of chemical additives that have the functions of penetrating, emulsifying, washing, dispersing and wetting added in scouring are called scouring agents. In a broad sense, chemicals such as acids, alkalis, oxidizing agents, reducing agents and various surfactants added during the scouring process can be called scouring agents. However, in the textile industry, when it comes to scouring agents, it is mostly a narrow concept, mainly referring to various anionic, nonionic surfactants and appropriate additives, which are obtained through a certain proportioning method and have a cleaning effect. It is the main ...
