In the present study, cotton fiber was treated with phosphorus trichloride in the presence of oxygen. As a result of the subsequent hydrolysis of modified cotton fibers, phosphorus-containing fragments with acidic groups and chlorine atoms were introduced onto their surface. Afterward, silver-containing composites based on raw and modified cotton fibers were prepared using the chemical reduction method. The obtained samples were characterized in detail by Fourier transform infrared spectroscopy, ultraviolet-visible spectroscopy, X-ray powder diffraction, as well as by thermogravimetric analysis, scanning electron microscopy, and energy-dispersive X-ray analysis. A comparative bioassay experiment of four samples for gram-negative () bacteria, gram-positive () bacteria, and the fungus was carried out. These results showed the predominant antibacterial activity of the phosphorylated sample and the composite based on it. Thus, the development of these antibacterial cotton fibers using readily available reagents under relatively mild conditions could be used as potential industrial applications for the production of everyday medical textiles.
在本研究中，棉纤维在氧气存在的情况下用三氯化磷处理。经过改性棉纤维的后续水解，含酸性基团和氯原子的含磷片段被引入到其表面。之后，采用化学还原法制备了基于未处理和改性棉纤维的含银复合材料。通过傅里叶变换红外光谱、紫外可见光谱、X射线粉末衍射以及热重分析、扫描电子显微镜和能量色散X射线分析对所得样品进行了详细表征。对四种样品针对革兰氏阴性（）菌、革兰氏阳性（）菌和真菌进行了比较生物测定实验。这些结果表明了磷酸化样品及其复合材料具有主要的抗菌活性。因此，在相对温和的条件下使用易得的试剂开发这些抗菌棉纤维可作为生产日常医用纺织品的潜在工业应用。
