Abstract
A composite nonwoven fabric includes a stretched unidirectionally aligned nonwoven fabric in which filaments composed of a thermoplastic resin are unidirectionally aligned and stretched and a dry nonwoven fabric that is provided on one side of the stretched unidirectionally aligned nonwoven fabric and that includes thermal-bonding fibers as a chief component. The filaments of the stretched unidirectionally aligned nonwoven fabric and the dry nonwoven fabric are intertwined by a needlepunch process, following which the two fabrics are unified by a thermal calendering process to produce the composite nonwoven fabric.
