Abstract
Abstract A flat, cloth-like composite laminate including airlaid, nonwoven pulp web layers reinforced by a wetlaid bicomponent web layer. The bicomponent web layer has a sheath-core configuration, wherein the fiber component of the sheath member has a lower melting point than the fiber component of the core member. If desired, an adhesive material can be utilized between the bicomponent layer and the airlaid pulp web layer.
