Abstract
Disclosed are multicomponent fibers wherein at least one component forms an exposed surface on at least a portion of the multicomponent fiber which will permit thermal bonding of the multicomponent fiber to other fibers. The multicomponent fibers comprise two poly(lactic acid) polymers with different L:D ratios which provide biodegradable properties to the multicomponent fiber yet which allow the multicomponent fiber to be easily processed. The multicomponent fiber is useful in making nonwoven structures that may be used in a disposable absorbent product intended for the absorption of fluids such as body fluids.
