Abstract
The present invention relates to an acid dye-leveling composition comprising a piperazine substituted organosulfonate that is useful for imparting a dye leveling characteristic to fibers prior to, or during, the fiber dyeing operation. Also described is a process for preparing the dye-leveling composition, as well as a process for using the composition in the dyeing of fibers. The composition is particularly useful for treating polyamide fibers, such as nylon, but is also suitably used in the treatment of silk, wool, and other synthetic and natural fibers.
