Night military operations are so difficult since the invention of infrared detection devices for wide range of the electromagnetic waves’ spectrum (specially in the invisible near infrared region (NIR)). Hence, camouflage textiles must be printed, solution dyed or mass dyed with appropriate dyes and/or pigments having NIR reflectance according to their applied environment. Colors existing in most camouflage patterns are green, brown, olive, khaki and black. So, reflectance values of pigments and/or dyes formulations must be color matched with the reflectance values of these colors in the NIR band. NIR camouflage studies conducted on natural and synthetic fibers have determined the role of pigments and dyes and their concentrations on the reflectance values and properties of textiles. Also they could show acceptable methods for production of the camouflage textiles and their uses in the invisible range of the electromagnetic waves’ spectrum. In this paper camouflage concepts and useful NIR camouflage dyes and pigments have been introduced, and then different methods of the textiles camouflage in NIR region have been reviewed.
