Acid leveling agent B-31 is built material of alkali sulfonate, can be used for nylon and wool dyeing, reduce initial rate of acid dyeing, promote leveling dyeing of anionic dyes. It has excellent property of leveling.

Characteristics and advantage
Excellent properties of leveling, retarding dyeing, synchronistic dye up-taking with mixed dye.
Excellent penetrating property, especially can be for beam dyeing of acid dye for nylon.
Enhance dye molecules diffuse into fiber’s interior equably, make fiber same color shade from surface to interior. 
Strong ability of migration, Has excellent repairing effect for dyeing defect on fabric from acid/weak acid dye.
Reduce listing, impart fabrics with pure and bright color shade.
