Abstract (en)
[origin: WO9721858A2] Permanently crimped fibres produced by three-dimensional texturing, and a method for making same, are disclosed. The fibres are advantageously produced by spinning and optionally stretching a filament roving. The roving is then fed to a three-dimensional texturing station then to a cutting device for cutting the roving into fibres having a predetermined length. The resulting fibres have high bulkiness and enable the production of non-woven surfaces having a remarkable abrasiveness as well as carpets with enhanced wear properties.
