PDADMAC Cationic Polyelectrolyte Polymeric Quaternary Ammonium Salt For Textile Color Fixing And Dye Effluent Decolorization | Bluwat Chemicals
PDADMAC Cationic Polyelectrolyte for Textile Color Fixing and Dye Effluent Decolorization
Bluwat Chemicals — polymer solutions for mills and ETPs
Overview
Bluwat Chemicals supplies PDADMAC, also known as PolyDADMAC or poly(dimethyl diallyl ammonium chloride), for integrated textile applications. As a color fixing agent in finishing and a decolorization agent in effluent treatment, this cationic polyelectrolyte provides strong charge neutralization, compact floc formation, and reliable clarification performance in dyeing plants and ETPs.
Why Choose PDADMAC for Textile Processes
- Improves dye uptake and color fastness, reducing back staining on fabrics.
- Acts as a powerful decolorization agent for reactive, disperse, and direct dye effluents.
- Works alone or with polyaluminum coagulants to optimize cost and performance.
- Wide operating pH window supports variable dye baths and ETP conditions.
