Abstract
Nonwoven fibrous webs including amorphous polymeric fibers with improved and/or more convenient bondability are disclosed. The nonwoven fibrous webs may include only amorphous polymeric fibers or they may include additional components in addition to amorphous polymeric fibers. The amorphous polymeric fibers within the web may be autogeneously bonded or autogeneously bondable. The amorphous polymeric fibers may be characterized as varying in morphology over the length of continuous fibers so as to provide longitudinal segments that differ from one another in softening characteristics during a selected bonding operation.
