Dyefix-CF is a solution that improves the color fastness of dyed fabrics. It helps fix reactive dyes permanently onto fabrics, protecting them from fading during washing, rubbing, perspiration, chlorine exposure, and other processes. Without a fixative like Dyefix-CF, unfixed dye portions can stain other fabrics during washing. Dyefix-CF significantly improves color fastness and retention, especially for reactive and direct dyeings, with little to no effect on shade, light fastness, or fabric handle and absorbency. It is formaldehyde-free and recommended for use in exhaust and pad dyeing processes.

2. Striking the right chemistry in fabric
The art of dyer is to reproduce gradation of
the colour requested by the customer & to fix it
permanently with a high level of fastness on
textiles.

3. “Dyefix-CF” a solution for dyer to improve
colour fastness of dyed fabric to:
Chlorinated water
Fastness to commercial laundering &
domestic washing
Perspiration
Water

4. A Perfect Binding Partner
Unfixed & hydrolyzed dyestuff portions are
responsible for poor fastness ratings. The loose
dyestuff stains other textile during the washing
process .
The higher the fastness requirements are, the more
important is the application of an efficient dyestuff
fixation system.
Dyefix-CF permanently protects reactive dyeing
against colour fading & makes optimal washing,
rubbing, perspiration & chlorine fastness ratings.
