BIOFIX NF PLUS is a high-performance, formaldehyde-free Fixing Agent designed to significantly enhance the wet fastness properties of reactive and direct dyes on cellulosic fibers. Operating effectively at a neutral pH, it works by forming a stable, protective cross-link between the dye molecules and the fiber. This prevents the bleeding of color during subsequent washing and ensures that the brilliance and shade of the dyed fabric remain intact over time, even under rigorous laundering conditions.
Key Benefits:
Superior Wet Fastness: Greatly improves resistance to washing, perspiration, and water staining, meeting stringent international quality standards.
No Shade Change: Specially formulated to minimize impact on the final color, preserving the original hue and brightness of the dyed material.
Formaldehyde-Free: Environmentally safe and compliant with modern eco-standards, making it suitable for "green" textile production and babywear.
Neutral Application: Its ability to perform at a neutral pH prevents the risk of fiber degradation and simplifies the process by reducing the need for extensive pH adjustments.
Application Guidelines:
Usage: Recommended for the after-treatment of cotton, viscose, and their blends dyed with reactive or direct dyestuffs. It is effective in both exhaust (batch) and continuous processes.
Dosing: Apply at 0.3 to 0.5 g/l in the final rinse bath. For dark shades or heavy-depth colors, the higher dosage is recommended to ensure maximum fixation.
