Title (EN) ABSORBENT ARTICLE CONTAINING A NONWOVEN WEB FORMED FROM POROUS POLYOLEFIN FIBERS
(FR) ARTICLE ABSORBANT CONTENANT UNE TOILE NON TISSÉE FORMÉ À PARTIR DE FIBRES DE POLYOLÉFINE POREUSES
Abstract: front page image
(EN)An absorbent article containing a nonwoven web that includes a plurality of polyolefin fibers is provided. The polyolefin fibers are formed by a thermoplastic composition containing a continuous phase that includes a polyolefin matrix polymer and nanoinclusion additive is provided. The nanoinclusion additive is dispersed within the continuous phase as discrete nano-scale phase domains. When drawn, the nano-scale phase domains are able to interact with the matrix in a unique manner to create a network of nanopores.
(FR)L'invention concerne article contenant une toile non tissée qui comprend une pluralité de fibres de polyoléfine. Les fibres de polyoléfine sont formées par une composition thermoplastique contenant une phase continue qui comprend un polymère de matrice de polyoléfine et un additif de nano-inclusion. L'additif de nano-inclusion est dispersé dans la phase continue sous forme de domaines de phase discrets à l'échelle nanométrique. Lorsqu'ils sont étirés, les domaines de phase à l'échelle nanométrique sont capables d'interagir avec la matrice de manière unique pour créer un réseau de nanopores.
