Improved fibers and yarns comprise propylene polymer and are characterized by a novel crystalline microstructure as determined by small angle X-ray diffraction. In addition, continuous filament yarns comprising filaments of propylene polymer are characterized by improved resilience as determined by compressional recovery tests. The fibers and yarns are useful in textile products.

L'invention concerne des fibres et des fils améliorés à base de polymère de propylène, dotés d'une nouvelle microstructure cristalline, tels que déterminés par un faible angle de diffraction des rayons X. L'invention concerne également des fils de filaments continus en polymère de propylène, présentant une souplesse améliorée, tels que déterminés par des essais de récupération sous compression. Ces fibres et ces fils sont utiles pour la fabrication de produits textiles.
