BIOFIX RC PLUS is a specialty Fixing Agent and "Red Cutter" specifically formulated to address the unique challenges of red, scarlet, and burgundy shades in reactive dyeing. Red dyestuffs are notoriously difficult to wash off and often suffer from poor wet fastness. BIOFIX RC PLUS works by specifically targeting and neutralizing the hydrolyzed (unfixed) red dye particles, preventing them from bleeding or staining adjacent white or light-colored fabrics. It provides a robust molecular lock that secures the color deep within the fiber, ensuring the shade remains vibrant and stable.
Key Benefits:
Specific Red-Dye Fixation: Optimized to stabilize the molecular structure of red reactive dyes, which are typically prone to high migration.
Elimination of Back-Staining: Actively "cuts" or neutralizes loose red dye in the bath, preventing it from re-depositing onto the fabric surface.
Superior Wash Fastness: Significantly improves the rating in ISO and AATCC wash fastness tests for notoriously difficult scarlet and wine shades.
Bright Shade Preservation: Enhances the depth of red tones while maintaining the clarity and brilliance of the original color.
Application Guidelines:
Usage: Recommended for the after-treatment of cotton and cellulosic blends dyed with reactive Red or Orange dyes. Highly effective for striped fabrics (Red/White) to prevent color bleeding.
Dosing: Apply at 1.0 to 2.0 g/l in the final rinse bath. Use the higher concentration for extra-deep shades or when processing fabrics with high contrast.
