Abstract

A method for forming a textile fusible sheet material includes producing a fibrous web from fibers on a laydown apparatus so as to form a backing ply and applying a mixture of a binder and a thermoplastic polymer to selected areal regions of the fibrous web. The method further includes thermally treating the fibrous web so as to dry and bond the fibers of the fibrous web using the binder to form a bonded fibrous web nonwoven fabric and so as to sinter the thermoplastic polymer with a surface of the bonded fibrous web nonwoven fabric.
