Abstract：
This article focuses on comparing the characteristics of cotton fabric dyed with Diospyros mollis extract (DME) solution and that of cotton fabric dyed with the reactive dye. The parameters of the cotton fabric after dyeing with both types of dyes were assessed, including color strength (K/S), structural morphology, infrared spectrum, antibacterial properties, UV resistance, color fastness to washing, rubbing, light, moisture absorption, breathability, and wastewater indices. The obtained results show that the K/S value of cotton fabric dyed with DME solution is slightly lower than that of cotton fabric dyed with the reactive dye, 18.52 and 19.36, respectively. The cotton fabric dyed with the reactive dye does not exhibit antibacterial activity against Escherichia coli and Staphylococcus aureus, whereas the antibacterial effectiveness against these bacteria for cotton fabric dyed with DME solution is 99.99 %. The UV protection capability of cotton fabric dyed with DME solution is superior to cotton fabric dyed with the reactive dye. The BOD/COD ratio of wastewater from the dyeing process with DME is higher than that of the reactive dye, with values of 0.70 and 0.32, respectively. The findings of this study indicate the superior ability of using DME solution as compared to the reactive dye, which is promising as a natural dye for fabric in medical applications.
摘要：
本文重点比较了用Diospyrosmollis提取物（DME）溶液染色的棉织物和用活性染料染色的棉织物的特性。对两种染料染色后的棉织物的参数进行了评估，包括颜色强度（K/S），结构形态，红外光谱,抗菌性能，抗紫外线,耐洗涤色牢度,摩擦,光,吸湿,透气性,和废水指数。结果表明，DME溶液染色的棉织物的K/S值略低于活性染料染色的棉织物，分别为18.52和19.36。用活性染料染色的棉织物对大肠杆菌和金黄色葡萄球菌不具有抗菌活性，而用DME溶液染色的棉织物对这些细菌的抗菌效果为99.99%。用DME溶液染色的棉织物的紫外线防护能力优于用活性染料染色的棉织物。DME染色废水的BOD/COD比高于活性染料，值分别为0.70和0.32。这项研究的结果表明，与活性染料相比，使用DME溶液的能力更高，这是有希望的天然染料织物在医疗应用。
