Color fixing agent 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 the sun.
Color fixing agent is an assistant used to improve the dyeing fastness of dyes on fabrics. As a kind of finishing agent, it can combine with the free ionic water-soluble group of the dye to form insoluble colored matter, which improves the washing and sweating fastness of the color, reduces the hydrophilicity of the dye, effectively improves the fixation rate of the dye, washability, rubbing fastness and dye utilization, and sometimes improves its light fastness.
The color fastness to washing and rubbing of dyed fabrics after fixation with color fixing agent has been significantly improved. It can significantly improve the color fastness of dyes to soaping, sweating, soaking and rubbing.
The color fastness of dyed fabric to washing shall be reasonably improved, which is not easy to cause the fabric to fade.
Improve the color fastness of reactive and immediately disperse dyes: including water cleaning, sweat stains, dyed fabrics, wet ironing, and water cleaning.
