ABSTRACT:
The present invention provides a nonwoven web or laminate having at least one surface with abrasion resistance and a low degree of free fibers on the surface. Also provided is a lofty nonwoven web laminate from multicomponent fibers having at least one surface with improved abrasion resistance and reduced fuzziness over other multicomponent fiber nonwoven webs. This nonwoven webs and laminate can be used where nonwoven webs and laminates are currently used, but are particularly suitable as a filter media. Also described is a method for producing a nonwoven web having at least one abrasion resistant surface. The process includes using a liner material between the forming surface and the forming nonwoven web, wherein the liner is removed after the nonwoven web is bonded. Removing the liner exposes the abrasion resistant surface of the nonwoven web or laminate.
