Abstract

The present invention relates to the preparation process of cationic compounded modifying orgnosilicon emulsion for raising the relaxation and shinkproof functions of fabric. The emulsioin is prepared through re-compounding with cationic emulsifier cetyl trimethyl ammonium chloride and non-ionic emulsifier alkylphenol erthoxylate, and composite emulsion copolymerization in the presence of catalyst potassium hydroxide with two kinds of silane coupling agents and orgnosilicon monomer to obtain translucent modifying emulsion. The modifying emulsion of the present invention has relaxation and shinkproof functions on fabric, especially protein fabric.

Description

Technical field: [0001] The invention relates to an organic silicon emulsion, in particular to a method for preparing a cationic compound modified organic silicon emulsion for improving the relaxation and anti-shrink performance of fabrics. It is mainly used to improve the relaxation and anti-shrinkage function of the fabric. It belongs to the technical field of chemical additives. Background technique: [0002] In the textile industry, silicone emulsion plays an important role in improving the fabric's handle, anti-shrinkage, washability and other functions. At present, most of the modified silicone emulsions used as softeners are prepared by a two-step method: first, amino-modified silicone oil is synthesized by bulk polymerization, and then micro-emulsified with a suitable emulsifier. The softness and relaxation function of the fabric treated with the emulsion prepared by this method is not ideal. Invention content: [0003] The object of the present invention is to ...
