Abstract

PURPOSE: To obtain an ultrafine fiber having improved drapability as clothing, soft touch and hand industrially and advantageously, by spinning a polyester with a spinneret having a specific hole diameter and length to control the spinning speed and distance immediately under the spinneret.
CONSTITUTION: A polyester, preferably polyethylene terephthalate, is melt spun by using a spinneret 1 having extrusion holes 2 with a hole diameter D of 0.05W0.25mm, preferably 0.1W0.2mm, and a hole length of 2DW4Dmm and at a distance of 1W3m immediately under the spinneret 1 and a spinning speed ≥1,500m or more, preferably 1,800m/min or more, to give a multifilament yarn of fineness per filament ≤1 denier.
