This invention relates generally to fibers and fabrics prepared using crystalline propylene polymer compositions comprising both propylene homopolymer and propylene copolymer. The propylene polymer compositions are prepared using at least one metallocene catalyst system in a polymerization process that involves the initial homopolymerization of propylene followed by the copolymerization of propylene with a small amount of comonomer. Fibers prepared with these propylene polymers are significantly more elastic and fabrics prepared with these polymers have a significantly broader bonding window which allows for more easy processing compared to fibers and fabrics prepared from known propylene polymers.

L'invention concerne de manière générale des fibres et des tissus préparés avec des compositions de polypropylène renfermant à la fois un homopolymère de propylène et un copolymère de propylène. Pour préparer ces compositions, on utilise au moins un système catalyseur renfermant un métallocène, dans le cadre d'un procédé de polymérisation qui comprend l'homopolymérisation initiale du propylène, suivie de la copolymérisation du propylène avec une petite quantité de comonomère. Par rapport aux fibres et aux tissus fabriqués avec les polypropylènes connus, les fibres préparées avec ce polypropylène sont nettement plus élastiques et les tissus préparés avec ledit polypropylène ont une fenêtre de liaison nettement plus large, ce qui facilite le traitement.
