  • Multilevel colorway carpet system
    Patent number: 4188430
    Abstract: A cut/loop or cut pile carpet having a beneath-the-surface patterning effect is fabricated from at least two yarn groups:(A) a multiple ply heat-set yarn having a relatively light dye affinity combined with a nonheat-set yarn having a first relatively darker dye affinity, and(B) a heat-set yarn having a relatively light dye affinity combined with a nonheat-set yarn having a second relatively darker dye affinity,so that the nonheat-set yarns shrink to a lower pile height than the heat-set yarn(s) due to heat and moisture during dyeing and drying the carpet, whereby at least two colorways are established in the carpet.
