Abstract
A synthetic yarn made from a blend of base fibers selected from the group consisting of polyester, nylon 6 and nylon 66, and 1-12 weight percent of a heat activated binder fiber having a melting point within the range of 165.degree.-190.degree. C., said binder fiber being made from a copolyamide which is derived from a mixture of 50 to 85 wt. % caprolactam, 0 to 40 wt. % hexamethylenediamine adipate or a combination of hexamethylenediamine and adipic acid, and optionally a salt selected from the group consisting of hexamethylenediamine dodecanedioate, hexamethylenediamine azeleate, hexamethylenediamine sebacate and hexamethylenediamine terephthalate; and a chain terminator selected from at least one of the group consisting of a fatty acid and a fatty amines, wherein said fatty acid or fatty amine include at least 14 carbon atoms. The binder fiber is capable of being pelletized into chips, leached and spun into yarn on a package without any significant sticking either of the chips to one another or the yarn on the package.
