Acidic Reduction Clearing Agent PR-511A
is a compound of special reducing agent, which has a better reducing
capacity in a wide range of PH value. It can replace (sodium hydrosulfite + caustic soda) for
reductive cleaning of polyester and its blended fabrics after dyeing, remove floating color, improve
the color fastness of the fabric

Ionicity：Nonionic
PH Value：7 ~8 (1% aqueous solution)
Solid content: 22%
Dilution: Water

Applications
◇ Polyester and its blended fabrics were dyed with disperse dyes, then reduction cleaning to
remove floating colors.
◇ Good chelation on metal ions, fabric has a bright color after cleaning
◇ The product basically has no irritating smell and can effectively improve the working
environment.
◇ It has a strong reducing effect in the acid bath, Basically, there will be no yellowing and color
shading in the traditional reduction cleaning process and does not affect the subsequent
process due to uncleanly cleaning of sodium hydrosulfite and caustic soda.

Technical process：
Dosage: 1～3.0 %（o.w.f）
After dyeing with disperse dyes, it is cooled to below 80°C to ensure the PH value is under weak
acidic conditions. add Acidic Reduction Clearing Agent, keep at 8-85°C for 20-30 minutes, then
drain and clean.
