    Abstract: PURPOSE:To provide the subject web having a soft touch, a mild luster and a deep color tone and useful for car seats by employing polyester fibers for the raised pulp section thereof, each of the polyester fibers having an elliptic cross section and a plurality of projections on the outer periphery thereof. CONSTITUTION:The objective raised pulp web having a pulp length of 1-4mm comprises polyester fibers wherein >=25wt.% of the polyester fibers comprise modified cross-sectional fibers each having an elliptic cross section having an average flatness degree of 1.5-2.5 and having 2-10 continuous projections on the outer periphery in the longitudinal direction of the fiber and wherein the relation between the single fiber denier (D) and pile length (L) of the fibers composing the pile section is simultaneously satisfied with equations: 0.7 =1.0 and D/2

    Abstract: PURPOSE:To provide the titled fiber having an essentially annular cross-section, by using a spinneret having a plurality of arc slits directing the concave side toward the center of the nozzle and melt-spinning a polyester through the spinneret under specific condition. CONSTITUTION:A polyester is spun at a spinning temperature of 275-295 deg.C through a spinneret composed of 2-6 arch slits directing the concave side toward the center of the nozzle (preferably, the gap Y between the slits is 0.07-0.15mm, the width W of the slit is 0.06-0.12mm, the radius of the inscribed circle R is 0.35-1.00mm and the depth of the slit is 0.25-0.70mm). The position of the spinneret is between 10cm below and 20cm above the bottom liquid level A in the heating thermal medium chamber 2 of a spinning machine.

    Abstract: PURPOSE:To obtain polyester multifilament yarn free from drawing unevenness, fluff, and slack, by winding undrawn yarn of polyester multifilament round a rotary feed roller and a drawing pin heated at specific temperatures, drawing it. CONSTITUTION:The undrawn yarn 3 of polyester multifilament having the total number of filaments of >=40 is fed to the hot rotary feed roller 7, wound round the hot rotary feed roller 7 heated at the temperature shown by the formula I (Tg is glass transition temperature; Ti is temperature of the hot rotary feed roller), is in contact with it for >=0.1sec and made to run, so that it is preheated. Then, the undrawn yarn 3 is wound round the drawing pin 8 having =0.48g/d heat shrinkage stress.

    Abstract: PURPOSE:To prevent the end breakage and loosening of filaments, by extruding molten polymer from a spinneret having the nozzle group to extrude the finest denier filaments closest to the blasting port of the cooling air, and disposing the nozzle groups to extrude larger denier filament further from the blasting port, and drawing and heat-treating the extruded filaments. CONSTITUTION:Combined filament yarn made of filaments having different deniers wherein the ratio of the maximum denier to the minimum denier is >=2, is extruded under molten state from a spinneret having a particular nozzle disposition, and the yarn is taken up with the hot rotary roller 14 acting as a take- up roller as well as a drawing roller. The combined filament yarn 11 is drawn between the roller 14 and the hot Nelson roller 16, and heat-treated with the roller 16. A combined filament yarn made of filaments having different deniers and free of end-breakage and looped loosening can be manufactured by this process.
