For example, in spinning, spinning, sizing, weaving or knitting, refining (refining and bleaching), dyeing, printing, finishing and other textile processing procedures, surfactants or surfactant-based auxiliaries must be used. , to increase efficacy, simplify processes, improve performance and improve quality.

In practical applications, surfactants are used as detergents, wetting agents, penetrants, emulsifiers, solubilizers, foaming agents, defoaming agents, smoothing agents, dispersing agents, leveling agents, and dye retarders , Fixing agent, refining agent, softener, antistatic agent, waterproofing agent, bactericide, etc. The earliest application in the textile industry is the non-ionic surfactant. Although its consumption ratio has gradually decreased in recent years, its consumption is still large compared to other industrial sectors, and it is widely used as a solubilizer, detergent, wetting agent, and dispersant. , emulsifier, leveling agent, refining agent, softener, antistatic agent, etc.

Among ionic surfactants, anionic surfactants are mainly used as detergents, penetrants, wetting agents, emulsifiers and dispersants, etc.; cationic surfactants can be firmly adsorbed on fabrics due to the negative charge of fibers. Commonly used as fabric softener, leveling agent, waterproofing agent, antistatic agent and color fixing agent; amphoteric surfactants are generally used as leveling agent, fabric softener and antistatic agent for metal complex dyes.
