With the improvement of material living standards, people's requirements for textiles are no longer limited to basic characteristics such as warmth and comfort. The development of functional textiles meets the special needs of textiles in the growing national economy and defense construction, providing fundamental guarantees for the survival, development, and prosperity of enterprises.
Textile printing and dyeing auxiliaries belong to textile fine chemical industry
Textile printing and dyeing auxiliaries not only increase the added value of textiles and improve their quality, but also play a crucial role in the matching and promotion of dye products.
Printing and dyeing auxiliaries can be divided into pre-treatment agents, dyeing auxiliaries, printing auxiliaries, and finishing auxiliaries.
Pre treatment agents: including penetrating agents, refining agents, oxygen bleaching stabilizers, chelating agents, extractants, etc;
Printing aids: including adhesives, thickeners, crosslinkers, emulsifiers, softeners, dispersants, and defoamers;
Dyeing auxiliaries: including leveling agents, fixing agents, dispersants, fluorescent whitening agents, etc;
Post finishing agents: including softeners, waterproofing agents, antibacterial agents, moisture wicking agents, anti-static agents, UV absorbers, etc
Pre treatment additives: mainly used to remove natural or artificial impurities from fabrics, fully utilizing the excellent characteristics of fabrics, such as whiteness, softness, and good permeability, to meet the needs of subsequent processes.
Pre treatment 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, fixing agents, fluorescent whitening agents, coating and printing auxiliaries, reducing agents, release agents, anti dyeing agents, stripping agents, dyeing agents, anti migration agents, etc.
Post finishing additives: Improve the appearance and internal quality of fabrics, enhance hand feel, stabilize shape, improve wearability, or endow fabrics with certain special functions such as anti shrinkage, anti wrinkle, flame retardant, anti-static, mold and bacteria prevention, anti fouling and oil prevention through physical and chemical processing.
Textile auxiliaries play an indispensable role in improving the product quality and added value of textiles. They not only endow textiles with various special functions and styles, but also improve dyeing and finishing processes, saving energy and reducing processing costs.
