Abstract

PURPOSE: A spinneret that has a slit nozzle orifice with bending parts such as V- shape, of which one end heads toward the center and the other turns clockwise or anticlockwise and has approach parts which are designed so that the speed of the polymer melt-extruded becomes higher, thus giving a new type of filament a spiral one.
CONSTITUTION: The spinneret has a slit nozzle orifice in which at least two bending parts 3 of, e.g., V-, L-, C- or U-shape are included and one end 1 heads toward the center part and the other 2 is arranged clockwise or anticlockwise as a whole and is designed to have following measures: the width of the slit, W; length, L1; the length between the center O and the bending part 3, L2; the length of the nozzle orifice, H; the diameter of the opening at the bottom, d; at the top, do; and the depth of the approach part, (h). A polymer such as polyester is melt spun through the spinneret to produce spiral fiber 4.
