Camouflage Military Uniforms of the 21st Century

In this paper, a part of the comprehensive research will be presented, which was performed as a part of a joint project of University of Zagreb faculty of Textile Technology and Croatian Ministry of Defence. One of the project aims wash defining the spectral characteristics of camouflage colours in VIS and NIR spectral area with retrospect on the role of design and new methodology based on macro/micro elements ratio in military camouflage pattern (versus currently adopted methodology of digital design). Also, the analyses of a spectral remission characteristics of chosen colours in compare to average shades of natural continental woodland environment have been performed over VIS and NIR spectrum in order to define them in a concept of camouflage effect achieving. In paper, also, a new technology INFRAREDESIGN® has been presented, which is based on resolving and controlling specific colorimetric characteristics and dyes properties in infrared spectrum. The technology processes hidden text, image or graphic, which is not visible by the eye in VIS spectrum but can be detected by using a new Z RGB camera only in NIR waveband. This technology is based on “Twin Dyes” preparation which have equal RGB values in VIS area but different Z values in NIR spectrum. The analyses of “Twin Dyes” performance in VIS and NIR spectrum has been performed.
