For reducing the cost of production and saving the environment, the utilization of chemicals, energy, and processing time should be minimized as much as possible. In this study, antimicrobial finishing of wool fibers was achieved by synthesizing Ag/Cu₂O/ZnO nanoparticles (NPs) in-situ on the surface of wool fibers, and subsequently dyeing with two natural dyes extracted from Pomegranate peels and Walnut Green husks. The extracted natural dyes had also noticeable antimicrobial activities. This decreased the consumption of Ag/Cu₂O/ZnO nanoparticles (NPs) for antimicrobial finishing of wool yarns. The wool samples were dyed at the initial dye concentration of 30 % over weight of fiber (o.w.f.), at 100 °C, pH 5.0 for 60 min. The treated samples were characterized by Scanning Electron Microscope (SEM), X-ray diffraction (XRD) analysis, reflectance spectrophotometer, and electromechanical tensile tester. The presence of nanoparticles was confirmed on the surface of the samples by SEM micrographs and XRD profiles. The mechanical properties of the treated samples improved slightly (less than 2%). The antimicrobial activities of the samples treated only with Pomegranate peels and Walnut Green husks were 65% and 35%, respectively. The antimicrobial activity of the treated wool yarns with inorganic salts after the dyeing process was excellent (almost 100%). Moreover, the wash and light fastness properties of the treated samples were all very good to excellent. The dyed sample treated with Ag salt maintained its high antimicrobial activity (>91%) even after 10 repeated washing cycles. The light-fastness of the dyed samples was improved from moderate (5) to very good (7-8) after treatment with the inorganic salts. The proposed eco-friendly dyeing process can also improve the antimicrobial properties of wool yarns.

为了降低生产成本并节省环境，应尽可能减少化学药品，能源和处理时间的使用。在这项研究中，羊毛纤维的抗菌整理是通过合成获得的Ag / Cu ₂ O / ZnO纳米颗粒羊毛纤维的表面上，并随后用来自提取的两个天然染料的染色上（NPS）原位石榴果皮和核桃绿壳。提取的天然染料还具有显着的抗菌活性。这减少了Ag / Cu ₂的消耗用于羊毛纱线抗菌整理的O / ZnO纳米粒子（NPs）。将羊毛样品以相对于纤维重量（owf）的30％的初始染料浓度在100°C，pH 5.0下染色60分钟。通过扫描电子显微镜（SEM），X射线衍射（XRD）分析，反射分光光度计和机电拉伸测试仪对处理后的样品进行表征。通过SEM显微照片和XRD图谱确认了样品表面上存在纳米颗粒。处理过的样品的机械性能略有改善（小于2％）。只有处理的样品的抗菌活性石榴果皮和核桃绿色果壳分别为65％和35％。染色后处理过的含无机盐的羊毛纱的抗菌性能极好（几乎100％）。而且，处理过的样品的耐洗性和耐光性均非常好至极好。用银盐处理过的染色样品即使经过10次重复洗涤后仍保持了较高的抗菌活性（> 91％）。用无机盐处理后，染色样品的耐光性从中等（5）提高到非常好（7-8）。拟议的环保染色工艺还可以改善羊毛纱线的抗菌性能。
