1. Exceptional Color Fixation

Uses cationic high-molecular-weight crosslinking to form dual ionic and covalent bonds with sulfur-indigo dyes

Greatly improves wash fastness, rubbing fastness, and perspiration fastness

Effectively prevents color loss due to washing, abrasion, or friction

2. Eco-Friendly & Safe

Free from formaldehyde, benzene, and other hazardous substances

Compliant with OEKO-TEX® Standard 100, REACH, and other international eco-standards

Low VOCs, ensuring a safer working environment and end-user safety

3. Strong Compatibility

Compatible with sulfur-indigo dyes, penetrants, softeners, and other auxiliaries

Can be directly added to fixation baths without impacting fabric hand feel, softness, or appearance

4. Superior Process Adaptability

Suitable for pad-dry-cure, immersion, and other common fixation processes

Minimal effect on fabric whiteness and tone, preserving the deep, vivid blue of sulfur-indigo

This fixing agent is specifically designed for sulfur-indigo dyed textiles requiring long-lasting, high-performance color retention.
