In order to match the reflectance profile of greenish leaf at NIR region, four commercially disperse dyes
were used to dye PET fabric, and the reflectance of dyed fabric and the transmittance of dye liquor in alcohol solution were measured by using a UV-Vis-NIR spectrometer with an integrating sphere. The effect of the combination dyeing, dyeing concentration (% owf) and fabric weave on the reflectance were also studied. The results show that the
reflectance of the combination dyeing is determined by one of the dyes whose reflectance curve emerges at longer wavelengths. C.I. Disperse Blue 56 plays an important role in green camouflaging. When the dyeing concentration of C.I. Disperse Blue 56 is 1 - 2% owf, the reflectance of dyed fabric almost overlaps that of greenish leaf in red shift region (region A). Fabric weave has little effect on the reflectance for the same dyeing program.
