In this study an effective nanocomposite antimicrobial agent for wool fabric was introduced. The silver loaded nano TiO(2) as a nanocomposite was prepared through UV irradiation in an ultrasonic bath. The nanocomposite was stabilized on the wool fabric surface by using citric acid as a friendly cross-linking agent. The treated wool fabrics indicated an antimicrobial activity against both Staphylococcus aureus and Escherichia coli bacteria. Increasing the concentration of Ag/TiO(2) nanocomposite led to an improvement in antibacterial activities of the treated fabrics. Also increasing the amount of citric acid improved the adsorption of Ag/TiO(2) on the wool fabric surface leading to enhance antibacterial activity. The EDS spectrum, SEM images, and XRD patterns was studied to confirm the presence of existence of nanocomposite on the fabric surface. The role of both cross-linking agent and nanocomposite concentrations on the results was investigated using response surface methodology (RSM).
本研究介绍了一种用于羊毛织物的高效纳米复合抗菌剂。通过在超声波浴中进行紫外辐射，制备了负载银的纳米 TiO(2)纳米复合抗菌剂。通过使用柠檬酸作为环保型交联剂，将纳米复合抗菌剂稳定在羊毛织物表面。处理后的羊毛织物对金黄色葡萄球菌和大肠杆菌均具有抗菌活性。增加 Ag/TiO(2)纳米复合抗菌剂的浓度可提高处理后织物的抗菌活性。此外，增加柠檬酸的用量可提高 Ag/TiO(2)在羊毛织物表面的吸附，从而增强抗菌活性。通过 EDS 光谱、SEM 图像和 XRD 图谱研究证实了纳米复合抗菌剂存在于织物表面。使用响应面法（RSM）研究了交联剂和纳米复合抗菌剂浓度对结果的影响。
