Abstract
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.
