Abstract: The invention is directed to composite nonwoven fabrics comprising a hydrophobic nonwoven web, a nonwoven web of thermoplastic meltblown microfibers and a hydrophilic nonwoven web comprising staple fibers. The nonwoven web of thermoplastic meltblown fibers is sandwiched between the hydrophobic nonwoven web and the hydrophilic nonwoven web and all of the layers are thermally bonded together via discontinuous thermal bonds distributed substantially throughout the composite nonwoven fabric.

Abstract: Multicomponent thermoplastic continuous filaments are provided, including hollow core multicomponent filaments. The filaments are at least partially splittable into smaller filaments in the absence of mechanical treatment or application of high pressure water jets. The surface energy of the component s can be controlled to control separation of the multicomponent filaments. Sub - denier and micro-denier filaments of low orientation can be produced from relatively high molecular weight polymers to produce nonwovens of surprising strength, barrier, and cover.

Abstract: The invention is directed to a composite nonwoven fabric comprising first and second nonwoven webs of spunbonded substantially continuous thermoplastic filaments, and a nonwoven hydrophobic microporous web of thermoplastic meltblown microfibers sandwiched between the first and second nonwoven webs. The filaments of the nonwoven spunbond webs are formed of continuous multiconstituent filaments which include a lower melting gamma radiation stable polyethylene polymer component and one or more higher melting gamma radiation stable polymer constituents, wherein a substantial portion of the surfaces of the multiconstituent filaments consists of the lower melting gamma radiation stable polyethylene constituent. The nonwoven hydrophobic microporous web is formed from a gamma radiation stable polyethylene polymer. The webs are bonded together to form the composite nonwoven fabric by discrete point bonds in which the polyethylene constituent of said multiconstituent filaments and the polyethylene of said third nonwoven web are fused together.

Abstract: The present invention provides composite nonwoven fabric laminates and processes for producing such. The fabric is comprised of a web of thermoplastic filaments laminated to at least one other web. Preferably, the filaments are spunbonded continuous polyolefin filaments which have an oxidatively degraded outer sheath portion to promote better interfilamentary bonding and improved fabric laminate strength. In a preferred embodiment, two outer nonwoven webs comprise oxidatively degraded spunbonded filaments and are positioned around and laminated to a web of meltblown microfibers thus forming an spunbond/meltblown/spunbond fabric. Additionally, a stretch compatible fabric may be formed in which a web of oxidatively degraded filaments is laminated to an elastic web. The fabrics of the invention may be advantageously used in numerous applications such as medical garments and disposable adsorbent products.
