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.
L'invention concerne des bandes fibreuses non tissées à fibres polymères amorphes ayant une capacité de liaison améliorée et/ou plus convenable. Ces bandes peuvent comprendre seulement des fibres polymères amorphes, ou bien renfermer d'autres composantes, en plus des fibres considérées. Lesdites fibres peuvent être liées de façon autogène dans la bande et avoir une morphologie variable sur la longueur des fibres continues, afin de présenter des segments longitudinaux qui diffèrent les uns des autres par leurs caractéristiques d'assouplissement durant une opération de liaison spécifique.
