ABSTRACT:
There is disclosed a process and a composition for dyeing polymeric fibers which have limited dye sites and/or difficult to penetrate chemical structures. Briefly stated, the process comprises the steps of contacting polymeric fibers with a dye composition comprising a disperse dye and a swelling agent. The fibers in contact with said dye composition are then preferably heated to a temperature and for a time sufficient to effect dispersion of a portion of said dye into said polymeric fibers. Subsequently, the fibers are treated to remove residual dye composition.
