With the improvement of material living standards, people's requirements for textiles are no longer limited to the original basic characteristics such as warmth and comfort. The development of functional textiles meets the needs of special uses of textiles in the growing national economy and national defense construction, and provides a fundamental guarantee for the survival, development and prosperity of enterprises.


Textile printing and dyeing auxiliaries belong to textile fine chemical industry
Textile printing and dyeing auxiliaries can not only increase the added value of textiles, improve the grade of textiles, but also play a vital role in the supporting use and promotion of dye products.


Printing and dyeing auxiliaries can be divided into pre-treatment agent, dyeing auxiliaries, printing auxiliaries and finishing auxiliaries.
Pretreatment agent: including penetrant, refining agent, oxygen bleaching stabilizer, chelating agent, extraction agent, etc.;
Printing additives: including adhesive, thickener, crosslinking agent, emulsifier, softener, diffuser and defoamer, etc.
Dyeing AIDS: including levelling agent, fixing agent, dispersant, fluorescent whitening agent, etc.
Finishing additives: including softener, water repellent, antibacterial agent, moisture absorption and perspiration additive, antistatic agent, ultraviolet absorber, etc

Pre-treatment additives: mainly in order to remove natural or artificial impurities on the fabric, give full play to the excellent characteristics of the fabric, such as white, soft and good permeability, to meet the needs of the subsequent process. Pre-treatment additives mainly include wetting agent, penetrant, bleach, cleaning agent and so on. Printing and dyeing auxiliaries refer to a series of auxiliaries used in the dyeing and printing process, in addition to dyes and coatings, mainly including emulsifier, dispersant, levelling agent, fixing agent, fluorescent whitening agent, coating printing auxiliaries, reducing agent, dye transfer agent, anti-stain agent, stripping agent, dye enhancer, anti-drift agent, etc. Finishing additives: Through physical and chemical processing to improve the appearance and internal quality of the fabric, improve the feel, stable form, improve the wear performance or give the fabric some special functions, such as anti-shrinkage, anti-wrinkle, flame retardant, anti-static, anti-mold, anti-fouling and anti-oil.


Textile auxiliaries play an indispensable role in improving the quality and added value of textile products, which can not only give textiles a variety of special functions and styles, but also improve the dyeing and finishing process, saving energy and reducing processing costs.
