Zusammenfassung:A process for forming a nonwoven fabric is provided. The process includes depositing at least a first nonwoven layer comprising a first plurality of interlaid individual meltspun fibers, which may comprise a plurality of monocomponent fibers having different onset of melting temperatures, bicomponent fibers having distinct fiber components having different onset of melting temperatures, and/or a plurality of different bicomponent fibers having one or more distinct components having different onset of melting temperatures, directly or indirectly onto a moving collection belt to form a precursor nonwoven. The process includes subjecting the precursor nonwoven web to a heat-setting operation (HSO) to heat-set the first plurality of interlaid individual meltspun fibers to form an intermediate nonwoven fabric, followed by consolidating the intermediate nonwoven fabric to provide that nonwoven fabric.
