ColTrit ® HS-250N

Acid fixing agent ColTrit ® HS-250N belongs to the polymerization of sulfonic acid condensates ａnd can form insoluble macromolecular compounds with dyes, thereby improving the fastness of dyes to water washing ａnd friction. It is a special fixing agent for fibers dyed with anionic dyes (acid dyes, metal complex dyes) such as wool, nylon, silk, leather goods, etc. After treatment, the dyed fabric has soap washing fastness, water washing fastness, ａnd sweat fastness The chlorine resistance ａnd fastness have been greatly improved, acid free, ａnd convenient to use.

Physical ａnd chemical properties:

Chemical composition sulfonic acid condensate polymer

Appearance: Dark reddish brown viscous liquid

Ionic anions

PH 2.0-4.0

Product performance:

1. Used for post-treatment of dyeing with polyamide fiber acid dyes to improve the wet fastness of acid dye dyeing;

2. It does not affect the color ａnd texture of the fabric, ａnd avoids the problem of fixed spots caused by conventional cationic color fixing agents;

3. According to the corresponding dyes used, the impact on sunlight fastness can be minimized;

4. It can prevent the white ground from staining during the fixation of printed fabrics;

5. No acid adjustment, convenient to use.
