Abstract

PURPOSE: The titled synthetic fiber filament yarn, capable of giving good crispy feeling and hand, having improved luster without glitter, and a specific cross- sectional shape and denier per filament.
CONSTITUTION: The number of lobes N in the cross section is 12≤N≤18, and the ratio M1 between the radius (r) of an inscribed circle in concave curves forming adjacent lobes and the distance to the apexes of the lobes present at the most distant place from the center O of the circle is in the range 1.10≤M1≤1.80. The ratio M2 between the radius (r) and the distance to the apexes present at the closest place from the center O of the inscribd circle is in the range M2≤M1≤2M2-1. The angle θ between the apexes of the adjacent lobes at the center O satisfies the relation 30≤N+θ≤46, and the denier D per filament of the filament yarn satisfies the relation N/9.M1≤D≤N/9.M1+15.
