Introduction to Textile Additives Dyeing and Finishing Additives

With the improvement of material living standards, people's requirements for textiles are no longer limited to their original basic characteristics 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 fundamental guarantees for the survival, development, and prosperity of enterprises.

Textile printing and dyeing auxiliaries belong to the category of textile fine chemicals

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 use and promotion of dye products.

Printing and dyeing assistants can be divided into pre-treatment agents, dyeing assistants, printing assistants, and finishing assistants.

Pre treatment agents: including penetrating agents, refining agents, oxygen bleaching stabilizers, chelating agents, extractants, etc;

Printing aids: including adhesives, thickeners, crosslinking agents, emulsifiers, softeners, dispersants, and defoamers;

Dyeing aids: including leveling agents, fixing agents, dispersants, fluorescent brighteners, etc;

Finishing auxiliaries: including softener, waterproof agent, antibacterial agent, hygroscopic and sweat wicking agent, antistatic agent, ultraviolet absorber, etc

Pre treatment additives: mainly used to remove natural or artificial impurities from the fabric, fully utilizing the excellent characteristics of the fabric, 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 auxiliary agents used in the dyeing and printing process, in addition to dyes and coatings, mainly including emulsifiers, dispersants, leveling agents, fixing agents, fluorescent brighteners, pigment printing auxiliaries, reducing agents, dyeing agents, anti dyeing agents, stripping agents, dyeing agents, anti migration agents, etc.

Post finishing additives: Improve the appearance and internal quality of fabrics through physical chemical processing, improve hand feel, stabilize form, improve wearing performance, or endow fabrics with certain special functions, such as anti shrinkage, wrinkle resistance, flame retardancy, anti-static, mold and bacteria resistance, pollution and oil resistance.

Textile additives play an indispensable and important 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.
