Abstract:
This invention relates to a nonwoven material consisting of one or more layers of nonwoven webs of essentially continuous cellulosic filaments, characterized in that within each layer each of the three bonding mechanisms: a) hydrogen bonding, b) filament intermingling and c) merged filament bonding occur for bonding the essentially continuous cellulosic filaments. Further it relates to a process for the manufacture and to various uses of this material.
