Abstract: Thermally insulative materials and articles are described. In one embodiment, the thermally insulative material comprises a polymer matrix, aerogel particles and expanded microspheres, wherein the aerogel particles are present in an amount of 30% by weight or greater, the polymer matrix is present in an amount of greater than or equal to 20% by weight and the expanded microspheres are present in an amount of 0.5% to 15% by weight, the percentages being based on the total weight of the polymer matrix, the aerogel particles and the expanded microspheres; and wherein the thermal conductivity of the thermally insulative material is less than 40 mW/m K at atmospheric conditions.

Abstract: Geometrically incised fabrics that control reflectance and transmission in the visible, thermal, nIR, SWIR, and microwave/millimeter bands of the electromagnetic spectrum are provided. The incised fabrics include incised flaps that move about a hinged attachment portion into open and closed configurations. The incised flaps may be oriented in patterns containing overlapping, inverted incised flaps, overlapping inverted and non-inverted incised flaps, or in block patterns of incised flaps. Selective transmission of electromagnetic waves can be modulated by the geometry of the incised flaps and the amount of tension applied to the incised fabric. The incised fabric includes a composite material including an asymmetric ePTFE laminate, a metalized layer, an ePTFE membrane layer, and a textile. A second ePTFE asymmetric laminate and a metal layer may be attached to the composite material to form a reversible composite. Incised fabrics may be used to form selective, multispectral reflective covers and garments.

Abstract: A selectively reflective construct, and a method for making the construct, are described. In one embodiment reflectance, transmission and absorption properties may be controlled in multiple electromagnetic bands. A construct is described comprising a) a thermally transparent, visually opaque substrate comprising a polymeric material and a colorant, and b) a thermally reflective layer comprising a low emissivity component which is optionally transparent to radar signal.

Abstract: An invertible camouflage construction containing a base and two sided garnish is described herein. In an embodiment, the first side of the garnish includes a first pattern, and the second side includes a second pattern visibly distinct from the first pattern. The first side and second side are inverted to provide concealment in differing environments.

Abstract: A chemical protective garment or ensemble is disclosed that comprises a impermeable, protective cooling laminate having a water-holding layer for holding and evaporating liquid, and a chemical barrier. The water-holding layer has a water-holding capacity of at least about 5% wt., and the suit is designed to retain sufficient liquid to provide cooling to a wearer upon evaporation of the liquid from the suit.

Abstract: The present invention is an improved glove having a fit enhancing, moisture absorbent component attached to the interior of the gauntlet of the glove on at least a portion thereof. The fit-enhancing, moisture absorbent component, or gauntlet insert, provides a closer fit of the glove around the wearer's wrist than the fit provided by the glove shell itself in the absence of the gauntlet insert. In addition, the gauntlet insert provides moisture absorption to collect perspiration which runs from the hand to the wrist area, as well as perspiration which runs from the arm toward the hand during use by the wearer. Both the fit and absorption features of the gauntlet insert provide for improved tactility, dexterity and comfort to the wearer during use.

Abstract: A textile material having thermal image masking or suppression in the mid and far infra-red region without compromising the effectiveness of visual and near IR camouflage or comfort level, or the effectiveness, and mobility of a person. Specifically the invention is directed to an air permeable, moisture vapor transmissive, waterproof, heat reflecting material consisting essentially of at least one metallized microporous membrane, with an oleophobic coating over the metallized portions thereof. This membrane is laminated to at least one other layer or textile backing material such as woven, nonwoven or knitted nylon, polyester, cotton, silk, etc. or additional microporous layers, in which the metal in the metallized membrane forms a discontinuous layer on the surface and on the pore walls adjacent the surface of the microporous membrane.
