A melt spinnable multicomponent fiber is provided that comprises a first component comprising a starch insolubilizing agent and a thermoplastic polymer, and a second component comprising destructurized starch and a plasticizer. The insolubilizing agent acts on the starch of the second component to render the starch less soluble when the fiber is exposed to water. The invention is also directed to nonwoven webs and disposable articles comprising the multicomponent fibers.
L'invention concerne une fibre à multicomposants pouvant être filée par fusion. Cette fibre comprend un premier composant comprenant un agent insolubilisant l'amidon et un polymère thermoplastique, ainsi qu'un second composant comprenant de l'amidon déstructuré et un plastifiant. L'agent insolubilisant agit sur l'amidon du second composant de façon à rendre cet amidon moins soluble lorsque la fibre est exposée à l'eau. L'invention concerne également des voiles non-tissés et des articles jetables comprenant ce type de fibre à multicomposants.
