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