Abstract
Yarn suitable for tufting comprises a base fiber ring spun or wrap spun with a second fiber at least partially comprising a heat-activated adhesive material such that the yarn includes from 0.1 to 12, preferably 0.25 to 10, weight percent adhesive material having a melting point within the range of 105.degree. to 190.degree. C, more preferably 165.degree. to 190.degree. C. A preferred base fiber is a synthetic staple fiber bundle. A preferred wrapping or insert fiber comprises copolyamide material, including ternary copolyamides of the 6/66/12 type. When the yarn is twist set by conventional processes and then tufted into carpet, the resulting carpet displays enhanced wear and appearance properties.
