Abstract
Disclosed herein are bicomponent fibers comprising first and second polymer components present in distinct portions of the cross section of the filament, wherein the first polymer component of the filaments is partially crystalline and serves as the matrix component of the filaments and the second polymer component of the filament is amorphous and serves as the binder component of the filaments, and wherein the fibers exhibit a single melting peak as evidenced by a differential scanning calorimetry (DSC) trace. Also disclosed herein are methods of making bicomponent fibers and nonwoven fabrics.
