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 fabric used to fabricate a garment or a protective cover includes a top and bottom textile layer and an air permeable, moisture-vapor-transmissive, expanded polytetrafluoroethylene middle layer. The fabric exhibits an MVTR rating of at least 4000 g/m2/day. The fabric may also include a top layer coating or fiber treatment of a nano-ceramic material designed to increase the durability of the garment/cover and increase the resistance to abrasion and wear while also resisting environmental conditions including exposure to solar radiation, temperature and humidity. Alternatively, the upper layer of the multi-layer fabric may incorporate ceramic coated fibers or ceramic co-extruded fibers, or carbon nanotubes while in another embodiment may also feature a fire resistant application as well as a permanent, highly breathable and highly durable electro-static discharge feature added to the inside of the layer by laying down a carbon based printed pattern on the inside of the layer.

Abstract: An enhanced protective cover includes a top and bottom textile layer and an air permeable, moisture-vapor-transmissive, expanded polytetrafluoroethylene membrane layer located between the two textile layers. The cover exhibits an MVTR rating of at least 4000 g/m2/day. The protective cover also includes a top layer coating or fiber treatment of a nano-ceramic material designed to increase the durability of the cover and increase the resistance to abrasion and wear while also resisting environmental conditions including exposure to solar radiation, temperature and humidity. Alternatively, the upper layer of the protective cover may incorporate ceramic coated fibers or ceramic co-extruded fibers, or carbon nanotubes. The protective cover may also feature a fire resistant application. The top textile layer may also include a permanent, highly breathable and highly durable electro-static discharge feature added to the inside of the layer by laying down a carbon based printed pattern on the inside of the layer.
