SYNTHETIC YARN WITH HEAT-ACTIVATED BINDER FIBER ABSTRACT OF THE INVENTION Synthetic yarn comprises a blend of base fiber selected from the group consisting of polyester, nylon-6 and nylon 6,6 and 1-12 weight percent, preferably 1-8 weight percent, of a heat activated binder fiber with a melting point within the range of 110-170°C, preferably 130-160°C. A preferred binder fiber is a copolyamide fiber, including ternary copolyamides of the 6/66/12 type. When the yarn is twisted, plyed and twist set by conventional processes and the treated yarn tufted into carpet, the resulting carpet displays enhanced wear and appearance properties.
