Abstract: Nonwoven fabrics are provided that include (i) a plurality of continuous matrix fibers comprising a first polymeric material having a first melting point and including a first polymer component, in which the first polymer component comprises a first recycled-polyester, and (ii) a plurality of binder fibers having an irregular cross-section randomly dispersed throughout the plurality of matrix fibers, in which the plurality of binder fibers comprising a second polymeric material having a second melting point including a second polymer component. The second melting point being less than the first melting point.

Abstract: 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.
