    Abstract: A filamentary structure comprises a spiral thermoplastic core filament disposed within a thermoplastic sheath component, consisting either of a tube or of at least three thermoplastic filaments, the sheath component being joined to the successive turns of the spiral core filament. The spiral core filament and the sheath component may comprise the same or different thermoplastic polymers, suitable polymers being polyamides, polyesters and polyolefins.The core filament and the sheath component may be extruded together from a spinning jet, and a plurality of the filamentary structures may be extruded side-by-side so that their sheath components are joined together to form a fabric structure.

    Abstract: A method of making a filamentary structure comprising a spiral thermoplastic core filament disposed within a thermoplastic sheath component is provided. The method involves extruding together from an extrusion die filaments forming the core filament and the sheath component, with the core filament being extruded at a faster rate than the sheath component which causes the core filament to spiral, and cooling the extrudates to form a unitary structure. A plurality of the filamentary structures may be extruded side-by-side so that their sheath components are joined together to form a fabric structure.
