Research status and development of infrared camouflage textile materials

With the rapid development of infrared detection and tracking technology, the combat concealment and viability of various military targets are seriously threatened, and the demand for military infrared camouflage is increasingly urgent. Individual combatants, as small moving targets, have the characteristics of small size, strong mobility, complex and changeable background, etc. Their infrared camouflage is more flexible and accurate than the equipment and engineering camouflage. The infrared camouflage textile material is soft and portable, which is the main embodiment of the infrared camouflage technology for individual soldiers. It can be used for infrared camouflage clothing, military tents, sleeping bags, and other equipment. Its research and development have been highly valued by many countries. In this article, details of the working principle, preparation methods, and recent research progress of flexible infrared camouflage textile materials are summarized. First of all, from the military application of infrared technology and the principle of infrared camouflage, the development status of infrared camouflage textile materials is summarized, and the research results of near-infrared and thermal infrared camouflage textile materials are introduced. Secondly, the camouflage conditions and research directions of new multi-band recombination and adaptive infrared camouflage textile materials are discussed. Finally, the challenges and opportunities of the future development of infrared camouflage textile materials, especially adaptive infrared camouflage textile materials, are considered.
