Textiles functionalized with copper oxide nanoparticles (CuO NPs) have become a favourable material to inhibit the spread of diseases due to their anti-microbial properties. In the present work, a successful procedure for in situ growth of CuO NPs in textiles was developed. Results showed that the combination of in situ synthesis and pad–dry–cure method promoting a uniform and dense adsorption of nanoparticles on the surface of the fabrics. The CuO NP-coated fabrics was characterized using XRD, SEM, EDX, TEM, and FTIR techniques. The CuO NP-coated cotton fabrics showed better anti-bacterial activity against various bacteria’s namely Staphylococcus aureus, Escherichia coli, Pseudomonas fluorescens and Bacillus subtilis. Besides, it also showed better antifungal activity against Candida albicans. The CuO NPs impregnated cotton fabrics exhibit a bacterial reduction of more than 90%, which is sustainable even after 20 washing cycles. Therefore, the CuO NP-coated fabrics has great potential to be used as coatings for medical, cosmetic or sports fabrics.

用氧化铜纳米粒子 (CuO NPs) 功能化的纺织品由于其抗菌特性，已成为抑制疾病传播的有利材料。在目前的工作中，开发了在纺织品中原位生长 CuO NPs 的成功程序。结果表明，原位合成和轧染-干燥-固化方法的结合促进了纳米粒子在织物表面的均匀和致密吸附。使用 XRD、SEM、EDX、TEM 和 FTIR 技术对 CuO NP 涂层织物进行了表征。CuO NP 涂层棉织物对金黄色葡萄球菌、大肠杆菌、荧光假单胞菌和枯草芽孢杆菌等多种细菌表现出更好的抗菌活性。此外，它还显示出更好的抗真菌活性白色念珠菌。CuO NPs 浸渍棉织物的细菌减少率超过 90%，即使经过 20 次洗涤循环后仍可持续。因此，CuO NP 涂层织物具有很大的潜力用作医疗、化妆品或运动织物的涂层。
