Gemini quaternary ammonium salt style ultra-fining coating preparation and application process for fabric dyeing

Abstract

The invention discloses preparation and application techniques of a gemini hyamine type superfine coating used for fabric dyeing, belonging to the technical field of the textile chemical industry, the techniques are characterized in that gemini hyamine cation surface active agent, coating and deionized water are added to a reaction vessel, stirred, mixed evenly and scattered by a microjet disintegrator to prepare gemini hyamine typed superfine coating. The gemini hyamine typed superfine coating features good liquidity, dispersivity and stability. Dyeing is carried out on fabrics by the superfine coating by means of dip-dyeing or pad dyeing. The gemini hyamine type superfine coating prepared by the invention can be applied to dyeing of mixture fabrics, thus solving the common problems thatthe existing mixture fabric dyeing process flow is long and chromatic light is hard to control; color depth and vividness fabrics can be improved without carrying out cationization processing of fabrics, thus reducing dosage of bonding agent, improving feel of coating dyeing fabrics and dyeing fastness.

Description

technical field [0001] The invention relates to a preparation and application process of a gemini quaternary ammonium salt type superfine coating for fabric dyeing, and belongs to the technical field of textile chemical industry. Background technique [0002] In today's world, people's awareness of environmental protection and ecology is getting stronger and stronger. The global trend of textile printing and dyeing shows that paint printing and dyeing is more and more popular due to its advantages such as complete color spectrum, bright color, stable shade, convenient color matching, good reproducibility, high quality, less labor, low energy consumption, and less pollution. processing attention. However, there are still shortcomings such as poor color fastness, not deep dyeing, and poor hand feeling in paint dyeing, which limits the wide application of paint to a certain extent. [0003] After the paint is ultra-fine, it can make up for the shortcomings of paint dyeing, su...
