摘要
利用织物反射光谱法,测量不同结构的还原染料染棉织物的近红外反射光谱,并与绿色树叶相比,对其伪装机理进行探讨。结果表明,还原染料所染棉织物具有与树叶类似的反射光谱曲线,不同种类还原染料所染棉织物的反射峰所处的波段不同,即染料结构决定了棉织物的近红外反射光谱。染色织物的反射光谱主要由红移量最多的染料反射光谱决定。
Reflectance spectroscopy was used to measure the near-infrared reflection spectra of cotton fabrics dyed with vat dyes with different structures, and the reflection spectra measured were respectively compared with that of the green leaf, investigating its camouflage mechanism. The results disclose that the reflective spectral line of the cotton fabric dyed with the vat dye is similar to that of the green leaf and the wave peaks of dyed fabrics vary with the kinds of vat dyes,i.e .the near-infrared reflection spectra of the dyed cotton fabrics are determined by the structure of dyes, mainly by the dye which has the maximum red shift.
