Elastic synthetic polymer filament with multi-lobated cross-sectional profile
 An elastic synthetic polymer filament having a multi-lobated cross-sectional profile is composed of (A) a filamentary axial constituent extending along the longitudinal axis of the filament, and (B) 3 to 8 filamentary lobe constituents radically protruding from and extending along the filamentary axial constituent each having a constricted portion thereof through which each filamentary lobe constituent is connected to the filamentary axial constituent, the cross-section of the filament satisfying the relationship (I): EQU 1.3.ltoreq.d.sub.1 /w.ltoreq.10 (I) wherein d.sub.1 is a largest cross-sectional width of each filamentary lobe constituent (C).
