摘　　要：分别采用还原和分散染料对棉及涤棉混纺织物进行染色生产近红外迷彩伪装。研究表明：还原蓝L-MG和汽巴能蓝83962属于同一类染料；随着还原蓝L-MG染料浓度的增加，近红外反射光谱产生红移，可见光波段反射率峰值与红移量有关；当染料质量分数为1％～2％时，染色织物反射光谱和树叶反射光谱曲线最为接近；除蜂巢和缎纹组织外，染料浓度对可见光反射光谱没有影响，对近红外反射光谱曲线影响很小；近红外反射光谱与产生红移量最大的染料密切相关。In order to obtain NIR camouflage, the cotton and polyester/cotton fabrics were dyed by using vat dyes and disperse dyes respectively. The results indicate that the vat blue L-MG and 83962 are of the same class. The near-infrared reflective spectra of the dyed fabrics are shifted to the long wavelength as the concentration of vat blue L-MG increases, and the amount of red shift is correlated to the peak value of visible reflective spectra. When the concentration of the dye is 1% - 2 % （o. w. f）, the reflective spectra of the dyed fabric are very close to that of the green leaves in the NIR region. Except fabrics with satin or honeycomb weaves, the reflective spectra of the fabrics dyed with different dye concentration show no difference in the visible light region and very slight difference in the NIR region. The near-infrared reflective spectra of the dyed fabric are closely related with the dye which has the largest red shift in the NIR region.
