  • Reduction or prevention of dye bleeding
    Patent number: 8262742
    Abstract: The present invention relates to a method of applying dye and stainblocker to a substrate comprising cationically dyeable fibers which reduces or eliminates the need for subsequent reapplication of dye. The present invention solves the problem of cationic dye removal resulting from stainblocker application by providing a method wherein application of stainblocker precedes the application of dye to a substrate comprising cationically dyeable fibers. Surprisingly, the invention provides a method wherein the effectiveness of cationic dye application is improved when preceded by stainblocker application compared to stainblocker application preceded by cationic dye application. The substrate comprising cationically dyeable fibers preferably further comprises acid dyeable fibers wherein even more preferably, said cationically dyeable fibers and acid dyeable fibers are attached to a backing to form a carpet.
