Acid Release Agent VS-01

Acid release agent VS-01 is special organic acid ester compounds.

It can replace acetic acid in nylon or wool dyeing bath. As the temperature of the dyeing bath increases, it can release organic acids slowly,

then the pH value gradually decreases, which can control the dyeing rate, achieve the effect of leveling,

and eliminate the risk of uneven dyeing caused by adding acetic acid in the middle of dyeing.
