The goal of this paper was to study some chemical and physical effects of chitosan nano-hydrogels containing Rhus coriaria on cotton fabric. The finished fabrics showed antimicrobial effects against two pathogenic microorganisms, namely Staphylococcus aureus and Escherichia coli, and the particle size, as well as the effect of encapsulating sumac extract in chitosan nano-hydrogel on some physical and visual characteristics of fabrics, are then confirmed by using various methods, including antimicrobial testing, scanning electron microscopy, Fourier transform infrared spectroscopy and ultraviolet-visible spectroscopy. The encapsulation efficiency and release behavior of the samples are also studied. The as-prepared samples with higher sumac content have more ultraviolet (UV) absorbing activity (about 52%) than the un-treated sample, as well as excellent washing fastness and antimicrobial properties after five washing cycles. More specifically, these methods indicated negligible changes in color and thickness of treated cotton fabrics. Finally, the application of cotton fabric along with the synthesis of chitosan nano-hydrogel and sumac loading introduced a novel cotton fabric with high antimicrobial properties, washing fastness and UV protection property.

本文的目的是研究含Rus coriaria的壳聚糖纳米水凝胶对棉织物的化学和物理作用。成品织物对两种病原微生物，即金黄色葡萄球菌 和 大肠杆菌具有抗菌作用。 然后使用各种方法（包括抗微生物测试，扫描电子显微镜，傅立叶变换红外光谱和紫外可见光谱。还研究了样品的包封效率和释放行为。所制备的具有较高漆树胶含量的样品比未处理的样品具有更高的紫外线（UV）吸收活性（约52％），并且在五个洗涤周期后具有极好的洗涤牢度和抗菌性能。更具体地说，这些方法表明经处理的棉织物的颜色和厚度的变化可忽略不计。最后，
