A facile method, cost-effective and highly efficient with shortened-time operation was devised for unprecedented modification of cotton fabrics. This modification induced the formation of metallic and metal oxide nanoparticles within cotton fabrics in such a way that cotton samples loaded with AgNPs- or AgNPs/ZnONPs or AgNPs/ZnONPs/CuNPs respectively. Presence of the trimetallic nanoparticles concomitantly within microstructural features of cotton imparts durable antibacterial, UV protection and conductivity properties to yield ultimately cotton fabrics with multifunctional performance. The nanoparticles were formed and stabilized independently by Polymethylol compound (PMC) and functionalized polyethyleneimine (FPEI) as per one bath. The results obtained proved that the solution of these metal compounds are turned from colourless to yellow and black green colour up on addition of PMC or FPEI compound. It was found that UV-vis spectra display maximum surface plasmon peak of around 410-415 confirming the successful synthesis of AgNPs stabilized by PMC or FPEI chains. In addition, the results obtained indicated that the as formed nanoparticles are successfully deposited into the surface of cellulose fabrics and reveal changes in crystalline structure. Fabrics underwent structural changes during their treatments as per the designed practice exhibit multifunctional properties and manifold performance. The resultant treated cotton fabric gives good antibacterial properties event after 20 washing cycles additionally to the excellent ultra-violet properties and excellent electrical conductivity.
设计了一种简便、经济高效且耗时短的方法，用于对棉织物进行前所未有的修饰。这种修饰方式使得金属和金属氧化物纳米颗粒在棉织物内部形成，从而使棉织物分别负载 AgNPs-或 AgNPs/ZnONPs 或 AgNPs/ZnONPs/CuNPs。三金属纳米颗粒同时存在于棉纤维的微观结构特征中，赋予棉织物持久的抗菌、抗紫外线和导电性，最终实现多功能性能。纳米颗粒通过多醇化合物（PMC）和功能化聚乙烯亚胺（FPEI）在同一浴中独立形成和稳定。结果表明，这些金属化合物的溶液在添加 PMC 或 FPEI 化合物后会从无色变为黄色和黑绿色。发现 UV-vis 光谱显示出约 410-415nm 的最大表面等离子体峰，证实了 PMC 或 FPEI 链稳定的 AgNPs 的成功合成。此外，结果表明，所形成的纳米颗粒成功沉积到纤维素织物的表面，并揭示了晶体结构的变化。根据设计的实践，织物在处理过程中发生了结构变化，表现出多功能特性和多方面的性能。经过处理的棉织物具有良好的抗菌性能，即使经过 20 次洗涤循环后，其抗紫外线性能和导电性也非常出色。
