Smart Solution for Indigo Backstaining and Lycra Protection

In denim laundry processing, controlling indigo backstaining is essential to achieve clean, high-contrast wash effects. Antibak 7X from KDN Biotech (Shanghai) Co., Ltd. is a highly effective surfactant-based liquid anti-backstaining agent specifically designed to prevent the re-deposition of indigo dye during desizing and stone-washing processes.

Unlike conventional polymer or solid anti-backstaining agents, Antibak 7X provides excellent Lycra protection, ensuring that stretch fabrics retain their elasticity without bubbling or seam distortion — even under demanding enzymatic washing conditions.

Why Choose Antibak 7X?

Traditional rock-form anti-backstaining agents can cause elasticity loss, stitch bubbling, and inconsistent dye removal—especially when overdosed. Antibak 7X eliminates these issues while offering enhanced performance and versatility.

Key Advantages:

• Superior indigo dye prevention – keeps denim bright, clean, and evenly washed.

• Lycra-safe formulation – prevents bubbling and loss of stretch in Lycra-containing garments.

• Effective stain repair – can be used for after-rinsing stained garments to restore wash quality.

• Excellent compatibility – works with amylase and cellulase enzymes in both acid and neutral conditions.

• Low foaming – ideal for drum-type washing machines.

• Easy to handle – water-soluble and stable across a wide pH range.

Typical Characteristics

Application Guidelines

Antibak 7X can be used in multiple ways depending on the denim washing process:

Tip: For garments already stained after washing, Antibak 7X can be applied as an after-rinse remedy to remove residual indigo stains — a unique benefit not offered by traditional anti-backstaining agents.
