The function of fixing agent in fabric fixing was analyzed

Fixing agent can improve the color fastness of dyestuffs to wet treatment on fabrics. It can form insoluble colored fabric with dyes on the fabric, which can improve the color fastness to washing, perspiration and sometimes sunlight. And in the category of fixing agent, there are also many problems

There are many small categories. For example: color change fixing agent, turquoise blue fixing agent, aldehyde free fixing agent, chlorine bleach resistant fixing agent and so on. And the characteristics of different fixing agents are different. Take chlorine bleach resistant fixing agent and formaldehyde free fixing agent for example.

The color fixing agent can improve the washing fastness after fixation, and the color drop of fixing solution is very little, and it can effectively avoid peeling and color change. The fastness to soaping and perspiration of the fabric treated with chlorine bleach resistant fixing agent are improved significantly, and the chlorine bleach resistant fixing agent does not contain chlorine

Formaldehyde, in line with environmental performance. The color change of the treated fabric is very small and does not affect the original style of the fabric. Because of the reactive group in the molecule, aldehyde free fixing agent can combine with dye and fiber to improve the fixing effect. It can also improve the quality of direct dyes

The wet fastness and washing fastness of reactive dye dyeing or printing will not affect the handle and rewetting property of the dye.
