What is "Reduction Clearing agent"?

What is the Preparartion Process?

After dyeing polyester fibers with disperse dyes, the excess dye on the fiber surface is reductively degraded to remove the dye that affects dyeing fastness.
Generally, drainage is performed after dyeing and reduction clearing is performed under alkaline conditions. As a reducing agent under alkaline conditions, hydrosulfite and thiourea dioxide are used. In addition, after alkaline reduction clearing, neutralization process using acid is necessary.

NICCA proposes a processing recipe that contributes to process shortening and drainage volume reduction. Our recipe realizes reduction cleaning in the same bath after dyeing by using a reducing agent that exhibits reducing power under acidic conditions, and does not require a neutralization step.
