Soaping agent + reducing agent (sulfinic acid) + acid (acetic acid)

 

Advantages of reduction cleaning under acidic conditions

When the temperature is lowered to 80-90℃ after dyeing, the reducing agent can be directly reduced and cleaned without draining; compared with sodium hydroxide, the reducing agent used under acidic conditions is less consumed by air oxidation.

 

Reductive cleaning under acidic conditions is not a panacea. In fact, compared to alkaline reduction cleaning processes, reductive cleaning under acidic conditions is more effective for azo disperse dyes, and for anthraquinone disperse dyes, it is sometimes not as good as traditional alkaline reduction cleaning. Many dyeing factories use acidic reducing agents to find the reason why they are not as effective as alkaline reduction cleaning.
