Abstract
This study describes a parametric model of diffuse reflectance for the purpose of simulating the spectral response of near-infrared (NIR, 0.7-0.9 μm) and shortwave infrared (SWIR, 0.9-1.7 μm) absorbing dyes for tailoring the NIR-SWIR reflectance of fabrics. This model combines diffuse-reflectance theory with reference spectra for simulating absorption in fabric of NIR/SWIR absorbing dyes whose absorption spectra span the NIR/SWIR spectral range. Fabric samples consisting of a cotton blend were used as the test substrate for NIR/SWIR dye application. The results of this study demonstrate application of the parametric model for simulating NIR/SWIR spectral responses corresponding to variable dye and dye blend concentrations in fabrics.
