In this study, a viscose/polyester fabric was printed by disperse and vat dyes to match the reflectance characteristics of the NATO black and green hues with forest environment in the visible/near‐infrared (Vis‐NIR) reflection spectrum. The black and activated carbon nanoparticles were also added to the printing paste to match the reflectance of hues. Color components and Vis‐NIR reflective behavior of printed fabrics were measured by reflection spectrophotometer. The rubbing, washing and light fastness, water absorption time, air permeability, bending length, and crease recovery angle of printed fabrics were also studied. Additionally, the strength properties of samples were measured. The reflectance behavior of the samples showed that the use of the black and activated carbon nanoparticles results in diminution of the Vis‐NIR reflection. The strength, air permeability, and bending length of printed fabrics have decreased, while the angle of crease recovery and the time of water droplet absorption have increased. The rubbing, washing, and light stabilities of printed samples were also measured as appropriate.

还原/分散染料在可见/近红外区域中印制的粘胶/聚酯混纺织物的舒适度和反射特性

在这项研究中,粘胶纤维/聚酯纤维织物是用分散染料和还原染料印花的,以使NATO黑色和绿色的色泽与森林环境在可见/近红外(Vis-NIR)反射光谱中的反射特性相匹配。黑色和活性炭纳米颗粒也被添加到印刷浆料中以匹配色调的反射率。用反射分光光度计测量印花织物的颜色成分和Vis-NIR反射行为。还研究了印花织物的摩擦,水洗和耐光牢度,吸水时间,透气性,弯曲长度和折痕回复角。另外,测量样品的强度性能。样品的反射行为表明,使用黑色和活性炭纳米颗粒会导致Vis-NIR反射减小。印花织物的强度,透气性和弯曲长度降低,而折痕恢复角度和水滴吸收时间增加。还适当地测量了印刷样品的摩擦,洗涤和光稳定性。
