Colloidal nano silver was applied on the surface of cotton fabric and stabilized using 1,2,3,4-butanetetracarboxylic acid (BTCA). The two properties of antimicrobial activity and resistance against creasing were imparted to the samples of fabric as a result of the treatment with silver nano colloid and BTCA. The antimicrobial property of samples was evaluated using two pathogenic bacteria including Escherichia coli and Staphylococcus aureus as outstanding barometers in this field. The durability of applied nanoparticles, color variation, wettability and wrinkle recovery angle of the treated samples were investigated employing related credible standards. The presence of nano silver particles on the surface of treated cotton fabric was proved using EDS spectrum as well as the SEM images. Furthermore, the creation of cross-links was confirmed by the means of both ATR-FTIR and Raman spectra. In conclusion, it was observed that BTCA plays a prominent role in stabilizing silver nanoparticle. Besides, Wettability and winkle recovery angle of finished samples decreased and increased, respectively. In addition, it is noteworthy that no obvious color variation was observed.
纳米胶体银被应用于棉织物的表面，并使用 1,2,3,4-丁烷四羧酸（BTCA）进行稳定。经过银纳米胶体和 BTCA 的处理，赋予了织物样品抗菌活性和抗皱性能。使用两种致病菌，包括大肠杆菌和金黄色葡萄球菌作为该领域的杰出标杆，评估了样品的抗菌性能。采用相关可靠标准，研究了纳米粒子的耐久性、颜色变化、润湿性和折痕回复角。通过 EDS 光谱和 SEM 图像证明了处理过的棉织物表面存在纳米银颗粒。此外，ATR-FTIR 和拉曼光谱也证实了交联的形成。总之，观察到 BTCA 在稳定纳米银颗粒方面起着重要作用。此外，整理样品的润湿性和折痕回复角分别降低和增加。此外，值得注意的是，没有观察到明显的颜色变化。
