Abstract
Stain-resistant, multicolored cationic dyeable carpet fibers are space dyed with an acid dye or premetalized acid dye, heatset, then tufted together with undyed cationic dyeable nylon fibers into a carpet. The carpet is then overdyed with an acid dye or premetalized acid dye to selectively dye only the previously undyed cationic dyeable nylon fibers, without staining or discoloring the adjacent previously dyed fibers, resulting in a multicolored stain resistant carpet.
