Abstract: Disclosed herein are embodiments of a multi-layer nonwoven fiber material, and related methods of manufacturing the material. In one exemplary embodiment, the fiber material includes a first layer of directionally aligned fibers together with a second layer of randomly dispersed fibers dispersed over the first layer. Consistent with one exemplary method for manufacturing a nonwoven fiber material, the method includes dispersing a first plurality of fibers horizontally in one or more predetermined directions, as well as dispersing a second plurality of fibers horizontally in random directions. In such an embodiment, the second plurality of fibers is dispersed over the first plurality of fibers. Moreover, an exemplary embodiment of a roofing shingle employing a nonwoven fiber material as described herein is as disclosed.

Abstract: Self-supporting scrim or web structure, which is readily thermopleated, is provided for use in filter applications. The self-supporting scrim has very high porosity. When pleated and deployed for filter applications, the scrim or web structure retains the shape of pleats and contributes minimally to airflow resistance. The scrim or web structure is fabricated from synthetic fibers and latex binders using a wet laid process.

Abstract: A structural mat matrix having (a) a substrate which consists essentially of from 80% to 99% by weight fiberglass fibers and from 20% to 1% by weight wood pulp and (b) a binder which consists essentially of from 80% to 95% by weight urea formaldehyde and from 20% to 5% by weight acrylic copolymer. The binder bonds the substrate fiberglass fibers and wood pulp together and has from 5% to 15% by weight of said matrix, preferably 10% by weight of the matrix.
