Color fixing agent is an auxiliary used to improve the color fastness to wet treatment of dyes on fabrics. It can form insoluble colored fabric with dyes on the fabric to improve the color fastness to washing and perspiration, and sometimes to light. In the category of color fixing agents, there are also many small categories.

For example: color changing fixing agent, Cuilan fixing agent, formaldehyde free fixing agent, chlorine bleach resistant fixing agent, etc. The characteristics of different color fixing agents are different. Take chlorine bleach resistant color fixing agents and formaldehyde free color fixing agents for example.

Bleaching and fixing agent can improve the fastness to washing after fixation, and the fixation working solution has little color loss, which can effectively avoid peeling and color change. The fastness to soaping and perspiration of the fabric treated with chlorine bleach resistant fixing agent is significantly improved, and the chlorine bleach resistant fixing agent does not contain formaldehyde, which conforms to the environmental protection performance.

The color of the treated fabric becomes smaller, which does not affect the original style of the fabric. The aldehyde free color fixing agent can combine with dyes and fibers to improve the color fixing effect because of its reactive group in the molecule. It can also improve the wet fastness and washing fastness of direct dyes, reactive dyes or printed fabrics, without affecting the hand feel and re wettability of the dyed fabrics.
