Method for Producing a Multi-Layer Nonwoven Web Having Enhanced Mechanical Properties

摘要

A method for producing a multilayer nonwoven web including a monocomponent fiber layer and a multicomponent fiber layer is disclosed. The method may include the steps of spinning a plurality of monocomponent fibers at a beam of monocomponent fiber spinnerets and directing them toward a belt to form a monocomponent batt layer; spinning a plurality of multicomponent fibers at a beam of multicomponent fiber spinnerets and directing them toward the belt to form a multicomponent batt layer, wherein the layers are laid on the belt one superadjacent the other to form a batt; and bonding the batt in a pattern of thermal bonds to form a multilayer nonwoven web.
