Textile auxiliaries, often referred to as the "industrial MSG" of textile processing, are used in small quantities but directly determine the final quality of the fabric. Their raw material system, after long-term industry iteration, has formed a mature structure with surfactants as the core and functional auxiliaries as a supplement.

Basic Raw Materials: Surfactants Account for Over 80%
Currently, approximately 80% of textile auxiliary products on the market use various surfactants as their core raw material. These raw materials mainly come from the petroleum and oil industries and can be divided into four categories based on their ionic properties: Anionic surfactants are commonly used in scouring agents and soaping agents, relying on their excellent detergency and emulsifying abilities to remove natural impurities and weaving sizing agents from the fabric surface; Nonionic surfactants have stronger penetrating power and are the core components of leveling agents and penetrants, helping dyes to distribute evenly on the fiber surface; Cationic surfactants are mostly used in softener products, forming a lubricating layer on the fiber surface, giving the fabric a smooth feel; Amphoteric surfactants combine the advantages of multiple ions and are widely used in antistatic agents and multifunctional compound auxiliaries.

Functional Raw Materials: 20% of Components Determine Special Properties
The remaining 20% of functional auxiliaries are key to imparting various special added values to textiles. Among them, organosilicon polymers are the core raw material for high-end softeners, evolving from early dimethyl silicone oil emulsions to today's fourth-generation block-modified silicone oils, significantly improving the wash resistance and softness of fabrics. Bio-enzyme preparations and bio-based biodegradable raw materials are popular directions for green transformation in recent years, replacing traditional high-polluting components and reducing the ecological burden. In addition, there are flame-retardant functional components such as ammonium polyphosphate and phosphate esters, as well as various formaldehyde-free resins and chelating dispersants, each addressing different functional needs such as flame retardancy, wrinkle resistance, and metal ion complexation.

Most of these raw materials are not single pure products, but rather mixtures of homologous compounds. By blending them in different proportions, they can be adapted to the processing needs of different fibers such as cotton, linen, and synthetic fibers, supporting the efficient operation of the entire textile dyeing and finishing process.
