In this study, we present facile antimicrobial finishing of cotton textiles. Screen printing was used for surface-finishing of cotton using a printing paste containing silver nitrate. UVC irradiation was applied to convert silver nitrate into a color product, thus also changing the color of the textiles. The color, its strength and stability of samples, depend on absorbed UVC energy and the formula of the printing paste. Scanning electron microscopy with the energy dispersive X-ray spectrometry revealed formation of silver particles on cotton threads; X-ray diffraction analysis and the time-of-flight secondary ion mass spectrometry did not provide clear information on these products. Microbiological studies revealed that the samples inhibited proliferation of Escherichia coli, Bacillus subtilis and Staphylococcus aureus. Washing fastness tests confirmed resistance of the samples to at least 50 washings. Additionally, the inhibition zones increased as the number of washing cycles increased, which is unique for such samples. This work also presents an approach to the design of antimicrobially finished workwear.
在这项研究中，我们提出了一种简便的棉纺织品抗菌整理方法。采用含有硝酸银的印刷浆通过丝网印刷对棉织物进行表面整理。用 UVC 辐射将硝酸银转化为有色产物，从而改变纺织品的颜色。样品的颜色、强度和稳定性取决于吸收的 UVC 能量和印刷浆的配方。扫描电子显微镜和能量色散 X 射线光谱揭示了在棉线表面形成了银颗粒；X 射线衍射分析和飞行时间二次离子质谱分析并未对此类产物提供明确的信息。微生物研究表明，这些样品抑制了大肠杆菌、枯草芽孢杆菌和金黄色葡萄球菌的增殖。耐洗色牢度测试证实了这些样品至少经过 50 次洗涤的耐用性。此外，随着洗涤循环次数的增加，抑菌圈也增加了，这对于此类样品来说是独特的。这项工作还提出了一种设计抗菌工作服的方法。
