The invention relates to a thermal camouflage comprising a strengthening layer (4), e.g. a woven material, on which a polyethylene film layer (1), metallized on one side, has been laminated with the aid of fusion adhesive (3). On lamination the surface is embossed such as to make it mat. Since the polyethylene is transparent for infrared, it has low self-radiation. By means of the metal layer (2) there is obtained radiation insulation so that the outer layer (1) is in a thermal equilibrium which is hardly affected, e.g. by a warm object which is covered with the material, and the outer layer has a low emission ability of about 0.6-0.8, depending on thickness and pigmentation. By applying further layers (5), patchy images may be obtained with infrared reproduction in the wavelength ranges of 3-5 mu m and 8-14 mu m. |
