Surfactants are widely used in the textile industry. Such as spinning, spinning, sizing, weaving or knitting, refining (refining and bleaching), dyeing, printing, finishing, and other textile processing processes, surfactants or surfactant-based auxiliary agents should be used To improve efficiency, simplify processes, improve performance and improve quality. In practical applications, surfactants are used as detergents, wetting agents, penetrants, emulsifiers, solubilizers, foaming agents, defoamers, smoothing agents, dispersants, levelling agents, retarders , Color fixing agent, refining agent, softener, antistatic agent, waterproof agent, bactericide, etc. The earliest application of non-ionic surfactants in the textile industry, although its consumption rate has gradually declined in recent years, compared with other industrial sectors, its consumption is still large, widely used as a solubilizer, detergent, wetting agent, dispersant , Emulsifier, leveling agent, refining agent, softener, antistatic agent, etc. Among the ionic surfactants, the anionic surfactants are mainly used as detergents, penetrants, wetting agents, emulsifiers and dispersants, etc .; the cationic surfactants can be firmly adsorbed on the fabric due to the negative charge of the fibers. Commonly used as fabric softener, leveling agent, waterproofing agent, antistatic agent and color fixing agent; amphoteric surfactants are generally used as levelling agent for metal complex dyes, fabric softener and antistatic agent.
