This paper presents the characterization of cotton and wool fabrics modified by silver nanowires (AgNWs). The effect of reactive dyeing of wool and cotton fabrics on their modification with AgNWs was analyzed. Both fabrics were dyed using reactive dyes (yellow, red, blue) at four color intensities (0.5, 1, 2, and 5%). Dyed fabrics were characterized by the determined Kubelka-Munk's coefficient (/) ratio and vibrational spectra (Fourier transform infrared (FTIR) and Raman). Analysis of the amount of AgNWs applied on cotton and wool fabrics indicates that the presence of dye affects the surface modification with AgNWs depending on the type of fibers. While for cotton no significant differences were noted in relation to the color intensity, in the case of wool, the higher the dye contents, the more nanowires were deposited on the surface. Surface-enhanced Raman spectroscopy (SERS) effect accompanying AgNW modification was also observed on wool, similar to the previous study on cotton.
本文介绍了用银纳米线（AgNWs）改性的棉织物和羊毛织物的特性。分析了羊毛和棉织物活性染色对其用AgNWs改性的影响。两种织物均使用活性染料（黄色、红色、蓝色）在四种颜色强度（0.5%、1%、2%和5%）下进行染色。通过测定的库贝尔卡-蒙克系数（/）比值和振动光谱（傅里叶变换红外光谱（FTIR）和拉曼光谱）对染色织物进行表征。对施加在棉织物和羊毛织物上的AgNWs量的分析表明，染料的存在会根据纤维类型影响用AgNWs进行的表面改性。虽然对于棉织物，在颜色强度方面未观察到显著差异，但对于羊毛织物，染料含量越高，沉积在表面的纳米线越多。在羊毛织物上也观察到了伴随AgNWs改性的表面增强拉曼光谱（SERS）效应，这与之前对棉织物的研究类似。
