Abstract (en)
[origin: EP0078869A1] A filamentary structure 5 comprises a helical thermoplastic core filament 6 disposed within a thermoplastic sheath component consisting either of a tube or of at least three thermoplastic filaments 7, the sheath component being joined at 8 to the successive turns of the core fiiament 6. The core filament 6 and the sheath component may comprise the same or different thermoplastic polymers, suitable polymer being polyamides, polyesters and polyolefins. The core filament 6 and the sheath component may be extruded together from a spinning jet, and a plurality of the filamentary structures 5 may be extruded side-by-side so that their sheath components are joined together to form a fabric structure.
