Title (EN) POLYOLEFIN FIBERS AND NONWOVEN FABRIC PRODUCED USING THE SAME
(FR) FIBRES DE POLYOLEFINE ET NON-TISSE FABRIQUE A PARTIR DESDITES FIBRES
Abstract: front page image
(EN)Polyolefin fibers comprising a surface layer with a low orientation region and an inner layer with a high orientation region, characterized in that an orientation parameter of the low orientation region measured by a Raman spectroscopy is smaller than that of the high orientation region by not less than 2.2 and not more than 8.0. When these polyolefin fibers are used, a nonwoven fabric having a high strength and an excellent feeling can be provided. Since the fibers have a wide processing temperature range for the production of a nonwoven fabric by the point bonding method, a nonwoven fabric of a stable quality can be provided.
(FR)L'invention concerne des fibres de polyoléfine qui comprennent une couche superficielle comportant une zone à orientation faible et une couche interne comportant une zone à orientation forte, caractérisées par le fait qu'un paramètre d'orientation de la zone à faible orientation, mesuré par spectroscopie Raman, est inférieur à celui de la zone à forte orientation d'une valeur comprise entre 2,2 et 8,0. L'utilisation de ces fibres de polyoléfine permet d'obtenir un non-tissé ayant une résistance élevée et un excellent toucher. Comme les fibres ont une large plage de température de traitement pour la production d'un non-tissé par la méthode du liage par points, il est possible d'obtenir un non-tissé ayant une qualité stable.
