Abstract: An improved acoustic and thermal insulation batting for use, for example, between airframe ribs in aircrafts, and that is stable, lightweight, air permeable to mitigate corrosion issues as well as inherently fire resistant and sized and shaped such that there is no need for positive retention mechanisms owing to the nature of the batting which allows for a compression or friction fit in place. The batting comprises a foam insulation core over which is provided one or more barrier, facing and/or edge layers.

Abstract: A nanofiber based multi-layer filtration material suitable for use in providing air filtration to a user's respiratory system may be provided. as an air filtration garment and/or other air filterina devices such as a face mask, mask and garments or the like. The laminate includes a one or more fabric layer adjacent to one or more nanofiber layers.

Abstract: A multi-layer liner material for use as a thermal and acoustical insulator which is lightweight, breathable, hydrophobic, oleophobic and fire-resistant. A central insulation core layer is contacted on a first surface by a first highly breathable layer and on a second surface by a second highly breathable layer, such that these three layers are resistant to water or oil penetrating the insulation core layer causing the liner to gain weight. The first and second highly breathable layers are preferably made from inherently flame resistant fibers and treated with a fluorocarbon surface treatment for water repellency, UV resistance and mold/mildew resistance. The first highly breathable layer is adjacent a facing layer while the second highly breathable layer is adjacent a backing layer. At least one surface of one of the first or second highly breathable layers, or facing or backing layers may include a carbon printing pattern to provide ESD protection.
