![]() There is also provided, in accordance with an embodiment of the present invention, a camouflage garment, including a fabric as described above, wherein the fabric is cut and sewn so as to be worn over the body of an ambulatory human subject. In disclosed embodiments, the at least one second flexible fabric layer includes microballoons, a metallic film, and/or a conductive net. The perforations may have multiple different sizes and shapes, such as triangular or quadrilateral forms. Typically, the long-wave radiation scattered by the at least one second flexible fabric layer includes infrared thermal radiation and/or microwave radiation. The first and second flexible fabric layers are perforated by a non-uniform pattern of perforations extending over at least a part of the fabric. At least one second flexible fabric layer is joined to the first flexible fabric layer, and is configured to scatter long-wave radiation that is incident on the fabric. There is therefore provided, in accordance with an embodiment of the present invention, a fabric, including a first flexible fabric layer, having fabric emissivity properties in a visible radiation range that are selected so as to mimic ambient emissivity properties of a deployment environment of the fabric. SUMMARYĮmbodiments of the present invention that are described hereinbelow provide multispectral, multi-purpose camouflage materials that can be used in a wide range of different ambient conditions. The remission values of the color pigments are in a range that allows camouflaging in the visual-optical and near infrared. The sheet has a base textile with a glass filament, with a coating that contains aluminum powder on one side and a coating that contains color pigments on the other side. 7,244,684, whose disclosure is incorporated herein by reference, describes a thermal camouflage sheet for covering heat sources against identification in a thermal image. The base textile is provided with a free-standing polyester film to which a vapor-deposited coating that reflects thermal radiation has been applied on the side facing the heat source.Īs a further example, U.S. The tarpaulin comprises a base textile composed of a knitted or woven glass fabric on the side that is remote from the heat source with a compound whose reflectance values are in the region of a visual camouflage and/or in the infrared region. 7,148,161, whose disclosure is incorporated herein by reference, describes a thermal camouflage tarpaulin for hiding heat sources against detection in a thermal image. One or more nanomaterials are disposed on the vinyl layer, the camouflage pattern, or the laminate to provide thermal and/or radar suppression.Īs another example, U.S. A laminate layer is secured over the front surface of the vinyl layer, coating the camouflage pattern to provide protection to the camouflage pattern and strengthen the vinyl layer. Patent Application Publication 2010/0112316, whose disclosure is incorporated herein by reference, describes a visual camouflage system that includes a vinyl layer having a camouflage pattern on its front surface with a site-specific camouflage pattern. With the increasing importance of thermal and radar imaging in the battlefield, some camouflage fabrics are now designed to suppress infrared and/or microwave radiation, as well.įor example, U.S. Traditionally, camouflage fabrics have been colored and textured so as to make it difficult to visually distinguish the fabric from its surroundings. The present invention relates generally to multi-layer fabrics, and particularly to layered fabrics having multi-spectral camouflage capabilities. ![]()
