Abstract
PURPOSE: A thermoplastic synthetic resin is melt-spun through a spinneret with specific units of spinning hole and fused immediately under the spinneret to produce the titled yarn efficiently, which has good luster and high bulkiness and gives woven or knitted fabrics with a touch just like natural fiber.
CONSTITUTION: A fiber-forming thermoplastic synthetic resin such as polyamide or polyester is melt-spun using a spinneret with hole units in which the unit is composed of two groups of spinning holes of 0.4W1.0mm diameter arranged on the apexes of a penta- to octagon with a 0.4W1.0mm diameter circumcircle and the extruded multifilaments with round cross section are fused right under the spinneret to produce the objective yarn with substantially U-shaped cross section.
USE: The resultant yarn develops dry touch and the surface of resultant clothes is spun-like.
