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

Textile printing and dyeing auxiliaries belong to the textile fine chemicals industry

Textile printing and dyeing auxiliaries can not only increase the added value of textiles and improve the quality 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 pretreatment auxiliaries, dyeing auxiliaries, printing auxiliaries and finishing auxiliaries.

Pretreatment agents: including penetrating agents, refining agents, oxygen bleaching stabilizers, chelating agents, extraction agents, etc.;

Printing auxiliaries: including adhesives, thickeners, cross-linking agents, emulsifiers, softeners, diffusing agents and defoaming agents, etc.;

Dyeing auxiliaries: including leveling agents, color fixing agents, dispersants, fluorescent whitening agents, etc.;

Finishing additives: including softener, waterproofing agent, antibacterial agent, moisture absorption and perspiration additive, antistatic agent, UV absorber, etc.

Pre-treatment additives: mainly used to remove natural or artificial impurities on fabrics and give full play to the excellent properties of fabrics, such as whiteness, softness and good permeability, to meet the needs of subsequent processes.
Pretreatment additives mainly include wetting agents, penetrating agents, bleaching agents, cleaning agents, etc. 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 emulsifiers, dispersants, leveling agents, color fixing agents, fluorescent whitening agents, and pigment printing Auxiliaries, reducing agents, dye release agents, anti-dye agents, stripping agents, dye enhancers, anti-migration agents, etc.

Finishing additives: improve the appearance and intrinsic quality of fabrics, improve hand feel, stabilize shape, improve wearing performance or give fabrics certain special functions through physical-chemical processing, such as anti-shrinkage, anti-wrinkle, flame retardant, anti-static, anti-static, etc. Anti-fungal, anti-fouling and anti-oil, etc.
