Bulk recoverable nonwoven fabric, process for producing the same and method for recovering the bulk thereof

摘要

A bulk-recoverable nonwoven fabric comprising a nonwoven fabric of which constituting fiber is bonded to each other by an adhesive agent to bond fibers and which is fixed in a compressed state by a temporary adhesive agent having a melting temperature lower than the melting temperatures of the constituting fiber and the adhesive agent to bond fibers, a process for producing the bulk-recoverable nonwoven fabric and a method for recovering the bulk of the nonwoven fabric.
