Description

  The present invention is a laminated material including a cloth base material having a disguise performance by absorbing or reflecting infrared rays, which is difficult to be recognized for reconnaissance by an infrared scope, a night vision camera, etc. It is also used for clothing, personal equipment, and covers for ships, aircraft, tanks, and the like.

  Recently, new reconnaissance methods have been devised on the battlefield, and infrared light is used for this purpose. For example, when an infrared photograph is taken of a munitions facility or army on the ground surface from an aircraft, an image that can be distinguished from surrounding objects such as the munitions facility or the army is presented. In the same way, reconnaissance such as direct shooting with infrared night mirrors and infrared filters is also carried out.

  In the conventional battle clothing, in the visible light region, it is difficult to distinguish from plants by printing four-color camouflage patterns on the fabric surface. Also in the near-infrared region, it has been known to approximate the natural world by using a pigment that controls the reflectance of the pigment used for camouflage. However, at the present time when infrared cameras that detect far-infrared rays are being used for military purposes, conventional camouflage techniques have little effect and no effective means have been taken.

Patent literature is described below.
JP-A-5-132879 JP, 2003-262497, A In order to prevent such see-through by infrared rays, the clothing absorbs or reflects infrared rays having a wavelength of 780 to 1500 nm, which is particularly used for infrared imaging, and does not allow infrared rays to reach the skin, or It is conceivable to prevent infrared rays from the skin side from going out of clothing. Conventionally, so-called camouflage clothing is known as a fiber material imparted with infrared absorption or reflectivity.

A camouflage pattern is applied with a dye or pigment having infrared absorbing ability. Camouflage clothing needs to have a camouflage pattern on the entire surface of the clothing for that purpose, so that the texture is impaired, not only can not withstand high bending, expansion and contraction, wear, but also clothing to inhibit breathability The inner comfort is lost, and it is difficult to apply to clothing.

  In addition, for the purpose of the above-mentioned application proposed in Patent Document 2, a fabric A with a specific cut is fixed to a mesh base B to form a disguise base fabric. When the fabric A is partially fixed to the mesh fabric B in a state where the fabric A is slackened in a specific direction and / or stretched in another specific direction when being fixed to the mesh fabric B, the cut portion of the fabric A is Since it is fixed to the mesh ground B in an open state, the fabric part surrounded by the line of the cut rises from the fabric surface, and the body temperature is efficiently released to the outside air by making a three-dimensional cut into the base fabric. A camouflage base fabric that is difficult to be visually recognized by an infrared camera or the like by controlling heat storage has been proposed. However, the proposed disguise base fabric is intended to be used as a clothing using such a disguise base fabric and to be worn on clothing such as combat clothing, and is difficult to be visually recognized by an infrared camera or the like depending on the material of the base fabric. There is a concern that the performance of will be affected.

And the cloth base material layer 1 and the metal foil layer or the metal vapor deposition layer 2 are laminated | stacked through the adhesive bond layer 5a, the stretched resin film is used as the resin layer 4, and the ink pattern layer 3 is printed by printing on the one side of the film. The ink pattern layer 3 and the metal foil layer or the metal vapor deposition layer 2 of the base material on which the substrate is formed are laminated via the adhesive layer 5b.

  As shown in FIG. 2, as another example of the configuration of the laminated material for camouflage including the fabric base material of the present invention, as in the configuration shown in FIG. It is a laminating material 20 for impersonation including a cloth base material in which a layer or metal vapor deposition layer 2, an ink pattern layer 3, and a resin layer 4 as an outermost layer are laminated in order. Then, on the ink pattern layer 3 formed by printing on the metal foil layer or the metal vapor-deposited layer 2, the resin constituting the resin layer 4 is directly melt-extrusion coated or the resin as a main component without using an adhesive layer. Are laminated by a coating solution coating method.
