Textile and dyeing
Textile auxiliaries
Polyacrylamide
has the function of sizing, uniform dyeing and stabilization in textile
process. Anionic polyacrylamide is often used in this field.
Textile-sizing:
It can improve the smoothness, fineness and softness of fabric.
Stabilization:
Greatly reduce the broken yarn rate.
extile
auxiliaries: With flame retardant effect, and prevent static electricity
effectively.

Wastewater treatment
The
characteristics of printing and dyeing wastewater are high COD and high chroma
content. At present, polyacrylamide flocculant (PAM) is mostly used in the
treatment of printing and dyeing wastewater. Compared with traditional
coagulant PAC (polyaluminium chloride) and PFS (polyferric sulfate), PAM
flocculant has the characteristics of faster coagulation settling speed, smaller
sludge volume, lower residual amount of wastewater after treatment and lower
treatment cost. Non-ionic polyacrylamide and anionic polyacrylamide are usually
used to treat wastewater depending on the exact dyes.
