Multicomponent fibers

A multicomponent fiber having a shaped cross section is provided in this invention. The multicomponent fiber comprises: (A) at least one water dispersible polymer; and (B) a plurality of domains comprising one or more water non-dispersible polymers, wherein said domains are substantially isolated fr...

More Information
Summary:A multicomponent fiber having a shaped cross section is provided in this invention. The multicomponent fiber comprises: (A) at least one water dispersible polymer; and (B) a plurality of domains comprising one or more water non-dispersible polymers, wherein said domains are substantially isolated from each other by said water dispersible polymer intervening between said domains; and wherein said water dispersible polymer is present at the perimeter of the outside cross-section of said multicomponent fiber in a proportion of not greater than 55% water dispersible polymer. Articles produced from the multicomponent fiber are also provided.
