    摘要: Nonwoven fabric laminates suitable for use as semipermeable membrane (12) supports are provided. The fabric laminates generally include at least two layers: a spunbond layer (16) of continuous filament fibers and a wet-laid layer (18) of discontinuous filaments. The resulting semipermeable membrane supports provide an advantageous balance of properties, including smoothness, porosity, interlaminar adhesion, and flux properties.

    摘要: A nonwoven fabric includes a first composite layer that includes from about 50% to about 90% by weight non- thermoplastic absorbent staple fibers and from about 10% to about 50% by weight thermoplastic fibers. A preponderance of the fibers at a first outer surface of the first composite layer comprise non-thermoplastic absorbent staple fibers and a preponderance of the fibers at a second outer surface of the first composite layer comprise thermoplastic fibers. The nonwoven fabric further includes a second composite layer that includes from about 50% to about 90% by weight non-thermoplastic absorbent staple fibers and from about 10% to about 50% by weight thermoplastic fibers. The second composite layer is adjacent the second outer surface of the first composite layer. The nonwoven fabric further includes bonded regions wherein a portion of the thermoplastic fibers of the first composite layer are fused to a portion of the thermoplastic fibers of the second composite layer, and further wherein the bonded regions have a plurality of contiguous voids.
