Ⅰ. Brief introduction of color fixing agent
A Colour fixing agent is an auxiliary used to improve the fastness to wet of color in the fabric. It can form insoluble colored substances with dye in the fabric. The substances can improve fastness to washing and perspiration of color. Sometimes it can also improve the sun's fastness. And it can also be divided into a variety of small categories.
For example, there is a discoloration fixing agent, emerald green fixing agent, non formaldehyde dye fixing agent, chlorine bleaching resistant fixing agent, and so on. The characteristics of the different fixing agents are different. Here we introduce the chlorine bleaching resistant fixing agent and non-formaldehyde dye-fixing agent to you.
Ⅱ. The advantages of fixing agents
Bleaching fixing textile agent can improve washing fastness after fixing color, and the solid color working solution has very little color fall. It can also avoid the peeling light and color change. The fabric dealt with chlorine bleaching resistant fixing agent, soaping fastness, and perspiration fastness was significantly improved. And chlorine bleaching resistant fixing agent does not contain formaldehyde, which meets a criterion of environmental performance.
There is little color change in fabric which is dealt with chlorine bleaching resistant fixing agent and it does not affect the original style of the fabric. And as there is a reactive group in molecular of a non-formaldehyde dye-fixing agent, which can be combined with dyes and fibers to improve the fixation effect. It can also improve the wet fastness and washing fastness of direct dyes, reactive dyes, or printing materials, and will not affect the hand feeling and re-wettability of the dye.
