Abstract

PURPOSE: A specifically composed polyester of polyethylene terephthalate is used as the yarn-splitting component and it is combined with a polyamide to produce conjugate fibers, thus improving the release resistance before split and facilitating the splitting with an aqueous alkali.
CONSTITUTION: As the splitting component, is used polyester A containing 2.4 mol% or more, preferably 3W30mol% of ethylene 5-sodiumsulfoisophthalate and 70mol% of more ethylene terephthalate units. The polyester is conjugated with the polyamide component B to form conjugate fibers in which the polester component A forms the sea continuously and divides the polamide component B into several sections. Then, the conjugate yarns are treated with an aqueous alkali to dissolve the polyester component A, thus giving polyamide split yarns.
