PURPOSE:To obtain the titled fiber, having excellent adhesive property and good feeling, by drawing a sheath-core type conjugate fiber two of polyethylene as a sheath component and a polyester as a core component in a wet heat bath, crimping the two and then heat-treating the crimped fiber tow. CONSTITUTION:Polyethylene as a sheath component and a polyester, such as polyethylene terephthalate, as a core component are melt spun through a sheath- core type conjugate spinning nozzle, etc., and bundled to provide a sheath-core type conjugate fiber two, which is then drawn in a wet heat bath, such as a hot water bath, set at >=60oC and then crimped by a stuffing type crimper, etc. The crimped fiber two is subsequently heat-treated in a steam setter, etc., so as to provide >=75 deg.C, preferably 90-100 deg.C surface temperature of the crimped two to afford the aimed fiber.
