The invention provides a profiled polymer filament having an open hollow cross- sectional shape normal to the longitudinal axis of the filament, wherein the cross-section is dimensioned to prevent the filament from interlocking with a second filament of the same cross-section. The invention also provides methods of manufacture of such filaments by melt spinning a polyamide, and spinnerets suitable for use in melt spinning such filaments.

L'invention porte sur un filaments de polymère présentant une section transversale creuse ouverte, normale à son axe longitudinal, et dimensionnée pour empêcher le filament de s'entremêler avec un deuxième filament de même section transversale. L'invention porte également sur des procédés de fabrication desdits filaments par filage à chaud et sur des filières à cet effet.
