ABSTRACT:
A stretchable synthetic polymer composite filament useful for stretchable fabrics, comprises:
(A) an axial filamentary constituent;
(B) a plurality of composite lobe filamentary constituents consisting of protrudent filamentary segments (B1) outwardly protruding from the axial filamentary constituent (A) in different directions from each other and edge filamentary segments (B2) attached to outside ends of the protrudent filamentary segments (B1);
the axial filamentary constituent (A) and the protrudent filamentary segments (B1) consisting essentially of a synthetic thermoplastic elastomer (a), and
the edge filamentary segments (B2) consisting essentially of at least one synthetic thermoplastic low elastic polymer (b),
in which filament, when not under tension, the composite lobe filamentary constituents (B) are asymmetric with respect to at least one feature of the location thereof, and cross-sectional configurations and sizes of the protrudent and edge filamentary segments (B1 and B2), about the longitudinal axis of the filament, and are spirally coiled around the axial filamentary constituent (A) in alternately reversed two opposite directions.
