In this study, fumaric acid (FA) crosslinked carboxymethylcellulose (CMC) hydrogel (CMCF) based silver nanocomposites were coated on cotton fabric for antibacterial property for the first time. The performance of the nanocomposite treated cotton fabric was tested for different mixing times of hydrogel solution, padding times and concentrations of silver. The cotton fabrics treated with CMC hydrogel based silver nanocomposites demonstrated 99.9% reduction for both Staphylococcus aureus (Sa) and Klebsiella pneumonia (Kp). After one cycle washing processes of treated cotton fabric, there is no significant variation observed in antibacterial activity. From SEM and AFM analyses, silver particles in nano-size, homogenously distributed, were observed. The treated samples were also evaluated by tensile strength, thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR) analysis, fluid absorbency properties, and whiteness index. The treatment of cotton fabric with CMCF hydrogel did not affect the whiteness considerably, but increased the absorbency values of cotton.
在这项研究中，首次将富马酸（FA）交联的羧甲基纤维素（CMC）水凝胶（CMCF）基银纳米复合材料涂覆在棉织物上，以赋予其抗菌性能。测试了纳米复合材料处理过的棉织物的不同水凝胶溶液混合时间、浸渍次数和银浓度的性能。用 CMC 水凝胶基银纳米复合材料处理过的棉织物对金黄色葡萄球菌（Sa）和肺炎克雷伯菌（Kp）的减少率均达到 99.9%。经过一次洗涤循环处理后，棉织物的抗菌活性没有明显变化。从 SEM 和 AFM 分析中可以看出，观察到纳米级尺寸、均匀分布的银颗粒。还通过拉伸强度、热重分析（TGA）、傅里叶变换红外光谱（FTIR）分析、流体吸收性能和白度指数对处理过的样品进行了评估。用 CMCF 水凝胶处理棉织物不会显著影响其白度，但会增加棉织物的吸水性。
