Abstract

PURPOSE: To obtain the title yarn usable for clothing, having improved bulkiness, silky luster, and hand, and bent fat cross-sectional shape to satisfy specific relationships, by melt spinning a polymer through a spinneret with orifices of specific shape.
CONSTITUTION: A polymer is melt spun through a spinneret with orifices of partially cut annular slits to satisfy formulas I, II, and III: (L2 is the average length of concave and convex sides; W2 is the width of the slit; H2 is the horizontal maximum width of the convex side; V2 is the vertical maximum width; L2/W2 is the ratio of flatness; V2/H2 is the curvature). A quenching air is blown on the filaments immediately after spinning from the opposite side to the cut parts of the orifices, and the filaments are drawn to give the desired filament yarn to satisfy formulas IV and V: (L1 is the average length of the concave and the convex sides; W1 is the width of the curved surface (thickness); H1 is the horizontal maximum width of the convex side; V1 is the vertical maximum width.
