Abstract

PURPOSE: The titled filamentary fibers, consisting of a thermoplastic polymer, and having noncircular cross sections, an irregular and periodic change in cross-sectional area and cross-sectional shape in the long direction thereof and a moderate initial elasticity and a high elastic recovery.
CONSTITUTION: Filamentary fibers, consisting of a thermoplastic polymer, e.g. polypropylene, and having an irregular and periodic change in the cross-sectional area in the long direction and coefficient of variation in cross-sectional area [CV(F)] of 0.05W1.0 and an initial elasticity of 5g/denier and an elastic recovery (50% elongation) ≥70%.
EFFECT: Capable of giving woven and knitted fabrics having imporved feeling, touch and gloss and fibrous materials having improved cushioning property.
