Abstract

L'invention concerne un procédé amélioré servant à fabriquer des bandes en non-tissé de fusion-soufflage. On fabrique cette bande à partir d'un polymère thermoplastique catalysé par un complexe organométallique. Dans un mode de réalisation, par exemple, ce polymère est un polypropylène dont le fluage est inférieur à 1.000 grammes par 10 minutes et qui présente une plage relativement étroite de distribution de poids moléculaires. On peut utiliser ces bandes en non-tissé de fusion-soufflage dans une variété de domaines d'application et elles sont particulièrement bien adaptées à la production de stratifiés. On peut, par exemple, dans un mode de réalisation, combiner cette bande en non-tissé de fusion-soufflage avec au moins une bande de non-tissé filé-lié afin de créer un stratifié de non-tissé utile, par exemple, pour des torchons, des serviettes, des éléments d'habillement, des produits absorbant les liquides.
