This article presents some aspects of application the dispersive Micro- Raman Spectroscopy in textile fibers analysis. Research were dedicated to the methodology of surface enhancement Raman spectroscopy (SERS) studies on cotton fabric and possibility of its application in fibers characterization. Studies were carried out on dyed cotton fabrics modified by silver nanowires (AgNWs). Three reactive dyes (blue, yellow, red) and four color intensities (0.5%, 1%, 2% and 5%) were used. AgNWs colloid was deposited on undyed and dyed cotton fabrics by dipping and drying method. Dyed fabrics were examined by spectroscopic methods: FTIR ATR, Raman, UV-Vis Diffuse Reflectance Spectroscopy, Fluorescence Spectroscopy. Raman signal enhancement phenomena occurring on the silver nanoparticles increases the possibility of fiber and dye identification especially in the case of dyes used in cotton dyeing reveals fluorescence.
本文介绍了分散式微拉曼光谱在纺织纤维分析中的一些应用。研究致力于棉织物表面增强拉曼光谱（SERS）研究的方法学及其在纤维特性表征中的应用。研究对象是用银纳米线（AgNWs）改性的染色棉织物。使用了三种反应性染料（蓝色、黄色、红色）和四种颜色强度（0.5%、1%、2%和 5%）。AgNWs 胶体通过浸渍和干燥法沉积在未染色和染色的棉织物上。通过光谱方法对染色织物进行了检查：傅里叶变换衰减全反射（FTIR ATR）、拉曼、紫外可见漫反射光谱、荧光光谱。银纳米粒子上发生的拉曼信号增强现象增加了纤维和染料识别的可能性，特别是在用于棉染色的染料存在荧光的情况下。
