Abstract: PURPOSE:To obtain the titled fiber having excellent dyeability under normal pressure and high yarn strength and giving a dyed product having high fastness to light, by constituting the core component and the sheath component of a sheath-core composite fiber having a specific core ratio with respective specific polyester copolymers. CONSTITUTION:The core component of the objective fiber is a polyester copolymerized with 1.0-1.8mol% (based on the whole acid component) iso phthalic acid component (component S) containing metal sulfonate group and 1.0-15wt% glycol component having a molecular weight of >=120, and the sheath component is a polyester copolymerized with 2.1-6.5mol% component S (based on the whole acid component), 5-20mol% dicarboxylic acid component and 1.0-15wt% glycol component. The ratio of the core (B) is set within the range defined by the formula [S1 is copolymerization ratio (mol%) of the compo nent S in the core component; S2 is copolymerization ratio (mol%) of the compo nent S in the sheath component; G1 is copolymerization ratio (wt%) of the glycol component in the core component].

Abstract: PURPOSE:A melt-extruded polymer is taken up at a specific speed, solidified, and treated with the finishing oil by means of an applicator that has a groove of a specified width perpendicular to the yarn touch direction and of a specified length and a hole for feeding the finishing oil, thus producing high-quality synthetic fiber without splash of the oil even at a high-speed taking-up. CONSTITUTION:A melt-extruded polymer is taken up at a speed of higher than 5,000m/min, solidified and treated with a metered amount of the finishing oil by means of an applicator that has a groove 2 running in the yarn touch direction and a finishing oil-feed hole 3 before the groove wherein the width of the groove W in mm. and the length at which the yarn contacts with the groove L in mm. satisfy the equationI[V is the taking-up speed in m/min]and equation II[F is filament count; D is filament diameter at the finishing oil applying part; in case of modified cross section yarn, D is diameter of the circumcircle of the cross section].
