In this study, we present a successful simple method for printing and finishing of polyester and cotton fabrics using gold and silver nanoparticles (Au-NPs and Ag-NPs, respectively) as stable, fast colorants and functional components. The surface plasmon resonance (SPR) bands of the colloidal gold and silver NPs were observed at 520 nm and 450 nm, respectively, indicating the presence of spherical Au-NPs and Ag-NPs, which was further confirmed by TEM analysis. The printed samples were subjected to SEM, XRD and EDX analyses. The SEM images and EDX spectra unequivocally confirmed the existence of embedded NPs on the fabric surfaces. Both the cotton and polyester samples possessed excellent color fastness, as indicated from the color fastness test. The functional properties of the printed fabrics indicated that the incorporation of Au-NPs and Ag-NPs into the fabrics simultaneously imparted multifunctional properties such as stable brilliant colors, highly durable antimicrobial activity and very good UV-protection properties.
在本研究中，我们展示了一种成功且简单的方法，该方法使用金纳米颗粒和银纳米颗粒（分别为Au-NPs和Ag-NPs）作为稳定、快速的着色剂和功能成分，对聚酯和棉织物进行印花和后整理。胶体金纳米颗粒和银纳米颗粒的表面等离子体共振（SPR）带分别在520 nm和450 nm处观察到，表明存在球形的金纳米颗粒和银纳米颗粒，这通过透射电子显微镜（TEM）分析得到进一步证实。对印花样品进行了扫描电子显微镜（SEM）、X射线衍射（XRD）和能谱分析（EDX）。SEM图像和EDX光谱明确证实了织物表面存在嵌入的纳米颗粒。色牢度测试表明，棉和聚酯样品均具有优异的色牢度。印花织物的功能特性表明，将金纳米颗粒和银纳米颗粒掺入织物中可同时赋予多种功能特性，如稳定的鲜艳颜色、高度持久的抗菌活性和非常好的紫外线防护性能。
