<p>PURPOSE:To obtain the title yarn having excellent chemical resistance, etc., free from efflux of surfactant, comprising two kinds of polyolefins having different melting points by making constitution wherein the low-melting polyolefin containing a fatty acid monoglyceride partially comprises the surface of the yarn. CONSTITUTION:The objective yarn which consists of two kinds of polyolefins (two kinds of high-melting polyolefin such as crystalline polypropylene and low-melting polyolefin such as high-density polyethylene) having >=20 deg.C different melting points, contains 3-10wt.% fatty acid monoglyceride of stearic acid in the low-melting polyolefin, has a component ratio of both the polyolefins of (70/30)-(30/70) (by weight ratio) and is obtained by conjugate spinning in such a way that the low-melting polyolefin partially comprises the surface of the yarn. The yarn is heat-treated at a temperature >= the melting point of the low-melting polyolefin and <= the melting point of the high-melting polyolefin to give a molded article.</p> |
