In textile wet processing, particularly in denim washing and post-dyeing cycles, the re-adhesion of removed dyestuffs onto white parts or the fabric background (back-staining) is a significant quality hurdle. ABS is a specially modified polymeric anti-redeposition agent available in both powder and granule forms.

Polymeric Protection and Dispersion Mechanism

ABS functions by creating a protective barrier between dyestuff particles and the fibers within the bath.

• Superior Back-Staining Prevention: Encapsulates indigo or other dyes removed during the wash. It prevents the dye from settling back onto white pockets, labels, or light-colored weft yarns, ensuring high contrast.

• High Dispersing Power: Keeps dyestuff particles at a microscopic size to prevent aggregation, thereby increasing the overall cleaning efficiency of the wash bath.

• Surface Activity: Forms a temporary protective film on the fiber surface, physically hindering the adhesion of impurities and dyes.

Physical Form and Application Ease

• Powder Form: Offers rapid solubility and high concentration. It allows for precise weighing in automatic dosing systems and recipe preparations.

• Granule Form: Non-dusting, providing a cleaner working environment within the facility. It is more resistant to caking during storage and transport.

Areas of Usage

• Denim Washing: Used in enzyme washing, stone washing, and rinsing baths to prevent back-staining and maintain contrast.

• Garment Dyeing: In the post-dyeing washing processes of cotton and blended ready-to-wear items.

• Auxiliary Chemical Manufacturing: As a core ingredient in formulating complex washing and soaping agents.

• Cellulosic Fiber Processing: During the pre-treatment and washing stages of cotton, viscose, and linen.
