Textile auxiliaries play a crucial role in the production process of textiles. They not only enhance the quality of textiles but also impart various special functions to them. The following is a detailed introduction to the types of textile auxiliaries:

I. Pretreatment Auxiliaries for Dyeing and Printing

Pretreatment auxiliaries for dyeing and printing are mainly used in the pretreatment stage of textiles to improve the penetration and uniformity of dyes. They mainly include:

Penetrating agent: It improves the permeability of fiber materials, making the fabric fiber texture more uniform, thereby enhancing the penetration of dyes.
Wetting agent: It reduces the surface tension of water, making it easier for water to contact the fibers and fully soak the fabric, thus improving the penetration and uniformity of dyes.
Emulsifying agent: It is a surfactant that mixes water and oil, commonly used to emulsify oily auxiliaries so that they can be evenly dispersed in water, facilitating contact and mixing with the fabric.
Cleaning agent: It removes impurities and stains from the fabric surface, making the fabric cleaner and facilitating the penetration and fixation of dyes.

II. Dyeing and Printing Auxiliaries

Dyeing and printing auxiliaries are added during the dyeing process to help fix the dyes on the fibers and improve the dyeing effect. They mainly include:

Leveling agent: It increases the uniformity of dye distribution, promotes the penetration and diffusion of dyes, thereby achieving a better dyeing effect.
Fixing agent: It improves the fastness of dyeing and prevents the dyes from falling off.
Dispersing agent: It prevents dye particles from aggregating, ensuring the uniform distribution and dyeing effect of dyes.Defoaming agent: It eliminates foam during the dyeing and printing process, preventing the foam from affecting the dyeing effect.

III. Post-finishing Auxiliaries for Dyeing and Printing

Post-finishing auxiliaries for dyeing and printing are mainly used to improve the appearance, feel, and function of fabrics. They mainly include:

Softening agent: It improves the softness of the textile's hand feel, making the fabric smoother and more comfortable.
Waterproofing agent: It forms a waterproof film on the fabric surface, improving the waterproof performance of the textile.
Antistatic agent: It prevents static electricity from generating on the textile surface, improving the antistatic performance of the textile.
Oil-repellent agent: It forms an oil-repellent film on the fabric surface, preventing the fabric from being eroded by oil stains.

In summary, there are many types of textile auxiliaries, each with its unique function and role. Together, they constitute the secret weapon of textiles, providing strong support for the production and processing of textiles.
