Fast-permeation, low-form, and easy-degradation mercerizing penetrating agent, and preparation raw materials and preparation process thereof

Abstract

The invention belongs to the technical field of chemical engineering, and relates to an alkali-resistant penetrating agent used in cotton fabric mercerizing. The invention especially relates to a fast-permeation, low-form, and easy-degradation mercerizing penetrating agent, and preparation raw materials and a preparation process thereof. The invention assists in solving technical problems such as unreasonable technologies of prior art. The preparation raw materials comprises the components of, by mass: 45-50 parts of fatty alcohol sulfate salt, 45-50 parts of fatty alcohol ether sulfate salt, and 1-5 parts of an emulsification agent. Compared with prior art, the penetrating agent, the preparation raw materials and the preparation process have the advantages that: medium-carbon and low-carbon alcohols are adopted as main raw materials, and fatty alcohol sulfate salt is synthesized; separation, purification and structural characterization are carried out; and reasonable formulation is carried out. The preparation process is simple and easy to implement. The product has high quality and low cost.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and relates to an alkali-resistant penetrant for mercerizing cotton fabrics, in particular to a fast-penetrating, low-foaming, easily degradable mercerizing penetrant and its preparation raw materials and preparation process. Background technique [0002] Penetrants are a class of surfactants that allow liquids to penetrate quickly and evenly into a solid substance. In textile printing and dyeing production, penetrants are widely used, such as desizing, scouring, bleaching, wetting or dispersing of dyes, dyeing, sizing, resin finishing, etc. Generally, penetrants can be used in alkaline, neutral and acidic solutions. The application effect of the penetrant directly affects the quality of the product. For example, the traditional penetrant JFC is acid-resistant, alkali-resistant, and hard-water resistant. However, it is often not used in many dyeing and finishing processes due to the la...

AI Technical Summary

Problems solved by technology

The application effect of the penetrant directly affects the quality of the product. For example, the traditional penetrant JFC is resistant to acid, alkali and hard water, but it is often not used in many dyeing and finishing processes due to the influence of cloud point and foaming.

Traditional penetrants such as penetrant OT have been used in the domestic textile industry for a long time. These penetrants have disadvantages such as poor heat resistance, acid resistance, slow penetration speed, and many foams, which are difficult to meet the requirements of printing and dyeing processes.

For this reason, people have carried out a long-term exploration and proposed various solutions, but none of them have obtained a good solution.
