Abstract

The invention discloses a preparation method of a modified silicone oil surfactant for textile. The preparation method comprises the following steps: preparing hydrogen-containing silicone oil; preparing methyl methacrylate modified silicone oil; and preparing a polyether amide modified silicone oil surfactant to finally obtain the modified silicone oil surfactant. The preparation method provided by the invention is simple in process steps, easy to control, small in injury to a human body in an operation process, small in pollution, energy-saving, emission-reducing and short in reaction time; the prepared surfactant is good in stability, good in hydrophilcity, easier to self-emulsify and better in emulsion stability, and has the characteristics of low surface tension and high activity.

Description

technical field [0001] The invention belongs to the field of textile auxiliaries, and in particular relates to a preparation method of a modified silicone oil surfactant for textile. Background technique [0002] In the textile and apparel industry, silicone surfactant is an important auxiliary agent. This is because on the one hand, its raw material cost is low, it is non-toxic and environmentally friendly, and on the other hand, it can be used as a softener, waterproof agent, anti-melting finishing agent, anti-melting Antistatic agents, sanitary finishing agents, lubricants, defoamers and anti-shrinkage agents are used in post-treatment of fabrics to improve elasticity, make fabrics slippery, wrinkle-resistant, antistatic, moisture-absorbing and moisture-permeable, and easy decontamination. [0003] In recent years, with the rapid development of science and technology and people's higher and higher requirements for the application of silicone surfactants, it is difficult ...
