摘要： A spunbond nonwoven fabric is provided which is formed from continuous multiple component filaments which include a polyester component and a polyethylene component. The polyethylene component is a blend of high density polyethylene and a first linear low density polyethylene. The spunbond filaments are preferably formed in a sheath-core configuration with the polyester component in the core and the polyethylene component in the sheath. Composite sheets are provided which include the multiple component spunbond layer and a meltblown layer, wherein the meltblown fibers include a second linear low density polyethylene. The linear low density polyethylenes are preferably formed by polymerization of ethylene with an alpha-olefin co-monomer, where the same co-monomer is used in each of the first and second linear low density polyethylenes.

摘要： A composite sheet is provided that includes a first fibrous layer having a first side and an opposite second side, and a second fibrous layer bonded to the first side of the first fibrous layer. The first fibrous layer is a multiple component meltblown web comprised of at least 95 % by weight of meltblown fibers having an average effective diameter of less than 10 microns. The meltblown web is comprised of 10 % to 98 % by weight polyethylene and 90 % to 2 % by weight of a synthetic fiber forming polymer having a melt temperature greater than 140 DEG C or a glass transition temperature of at least 40 DEG C. The second fibrous layer is comprised of at least 95 % by weight of second layer fibers having an average effective diameter that is greater than the average effective diameter of the meltblown fibers of the first fibrous layer. The composite sheet has a basis weight of less than 120g/m , a grab tensile strength of at least 35 N, and a hydrostatic head of at least 10 cm.
