Product Description
Sodium hydrosulfite substitute RY-3207A
Introduction
It is a substance that can be used for reduction cleaning, lightening or color stripping in an acidic bath. It is environmentally friendly, safe and easily degraded.
bluesign certified products, ZDHC certified products
Characteristics
Compared with the traditional sodium hydrosulfite process, it can save 1-3 cylinders of water, acid neutralization process and water washing time.
The washed fabric has good color fastness.
The COD value of the residual liquid after cleaning can be reduced to more than 40%, and it is easy to degrade.
The cleaning residue can be recycled to dye the same color or darker colors without affecting the color light, color depth and color fastness of the dyeing.
[Carbon Emission] Compared with sodium hydrosulfite for reduction cleaning, RY-3207A reduces carbon emissions by about 600kg/1000kg cloth.
Basic Character
Composition：Inorganic reducing substance compound
