Abstract
Disclosed are multicomponent fibers which include a surface modified thermobondable non-biodegradable synthetic polymeric component and a biodegradable component. The surface modified thermobondable non-biodegradable component permits thermal bonding of the multicomponent fiber to other fibers with enhanced adhesion. The multicomponent fibers are useful in the manufacture of nonwoven structures, and in particular nonwoven structures used as a component in disposable absorbent products.
