Spectral simulation and materials design for camouflage textiles coloration against materials of multidimensional combat backgrounds in visible and near infrared spectrum

Abstract

Abstract Visible and near infrared spectra of “sixteen materials for textile coloration/ finishing/patterning” such as titanium dioxide, calcium oxide, aluminum, tin metal, tin oxide, iron powder, boron carbide, magnesium powder, carbon black pigment, titanium carbide, isolan black 2S LDN, isolan orange, telon blue A 2R, telon red A 2R, telon violet 3R and telon yellow A 2R; and ‘nine materials of combat backgrounds (CBs) such as dry leaves, green leaves, tree bark-woodland CB; water-marine CB; sand-desertland CB; stone-stoneland CB; snow-snowland CB; sky CB and ice-iceland CB (DGTWSIB) are obtained by Fourier transform infrared spectrophotometry and colorflex EZ spectrophotometer. A method of ‘Monte Carlo cross validation’ was applied for spectral simulation in visible and near infrared spectrums through experimental data information. The characterized reflection spectra of zero reflection (ZR), low reflection (LR), high reflection (HR) and HR-LR (HLR) materials are coalesced and simulated for camouflage materials design and textile applications against multidimensional CBs, DGTWSIB. The reflections of aluminium, titanium dioxide, calcium oxide, tin metal, tin oxide and iron powder are irradiated as HR materials. Oppositely boron carbide, magnesium powder, carbon black pigment and titanium carbide are illuminated as LR materials. Consequently, the mixing principle of HR and LR materials are also classified as HLR materials. Spectral properties of CB materials are also depicted as ZR materials against selected CBs. Spectral signal of ZR, LR, HR and HLR materials are identified as more expedient camouflage materials for concealment of target signature than six selected synthetic dyes such as Isolan Black 2S LDN, Isolan Orange, Telon Blue A 2R, Telon Red A 2R, Telon Violet 3R and Telon Yellow A 2R. The reflection spectra of ZR, LR, HR and HLR materials are simulated and correlated against DGTWSIB in visible and NIR spectrums. Simulated spectral signals are considered for camouflage materials design and camouflage textiles formulation against DGTWSIB combat location, the CBs are mostly practiced by defence professional. Furthermore, the reflection principle of camouflage textiles coloration/finishing/patterning has been accumulated under spectral signal of DGTWSIB, camouflage materials and synthetic dyes, synthetic dye-metal and synthetic dye-pigment combination. Therefore depth analysis and graphical results of ZR, LR, HR and HLR materials are the potential findings for selection of camouflage materials, right development of camouflage textile products and camouflage assessment of hyperspectral imaging for defence protection in entire spectrums of UV-visible-IR. This optical parameters of ZR, LR, HR and HLR materials have also applications to the materials community of multidimesional branches of material research.
