Poly Acid

Poly Acid is an organic acid that has unmatched performance in the fields of textile processing, leather tanning, coagulation of rubber latex, nickel plating baths, etc. Often substituted for acetic acid in the textile industry for dyeing and bleaching. Poly Acid is used in the textile industry for textile scouring and pre-enzyme treatment.

Poly Acid helps in obtaining a pH of 4.5 to activate the cellulase enzymes. Poly Acid neutralizes the alkalinity of the bath, promoting whiteness and further dyeing. Rinsing with Poly Acid and soap helps remove alkali, electrolytes, and unfixed dyes. Poly Acid is used to exhaust the dye bath in basic dyeing of cotton, silk, wool, etc. Poly Acid is added to bases in naphthol dyeing to neutralize the excess alkali. It functions as a reducing agent to convert hexavalent chromium to trivalent for mordanting. pH of Poly Acid provides the correct range for slow dye bath exhaustion, producing shades. For finishing process, 0.6 - 0.8% of Poly Acid gives a good shine and feel to the fabric. Poly Acid with amino plast resins is used to treat textiles for crease proofing, shrink proofing and other wash wear characteristics
