Stain resistant multicolor textured cut pile carpet: cationic-dyeable nylon yarn dyed with anionic dyes and anionic-dyeable nylon yarn

A process of preparing a stain resistant multicolored carpet comprising the successive steps of:

• (a) space dyeing a cationic-dyeable nylon yarn with an acid dye or a premetalized acid dye at a pH of from about 4.0 to 6.5 and fixing the dye to the fibers, the cationic dyeable nylon yarn dyed into predetermined colors, a predetermined pattern, or both, to intermittently dye the yarn different colors along the length thereof;
• (b) tufting the space dyed yarns of step (a) and an acid dyeable nylon yarn having an affinity to acid dyes into a carpet;
• and
• (c) dyeing the carpet prepared in step (b) with an amount of acid dye sufficient to selectively dye only the acid dyeable nylon fibers and not the previously space dyed cationic dyeable nylon fibers, to produce a multicolored stain resistant carpet.
