摘要

在 NaNO2 和 HCl 的存在下，通过重氮化苯胺和 3- 氨基吡啶，然后在碱性介质中与 2-甲基间苯二酚偶联，合成了新型偶氮化合物。利用傅立叶变换红外光谱、1H NMR 和 13C NMR 分析对这些化合物的结构进行了表征。本研究的主要目的是调查新偶氮结构在纺织工业中的着色应用以及抗菌和牢度特性。棉织物采用了排气染色工艺。测量了色强度（K/S 值）、L、a* 和 b* 值。偶氮化合物在棉织物上的色牢度值（耐摩擦、耐光、耐汗渍、耐洗涤）根据 ISO 标准进行了比较。根据 AATCC 147-2016 测试方法，对有色织物的抗菌活性进行了评估：金黄色葡萄球菌和肺炎克雷伯菌。使用 2-甲基-4-[吡啶-3-基二苯乙烯基]苯-1,3-二醇染色的织物对金黄色葡萄球菌具有可接受的抗菌活性。

An Investigation of Fastness and Potential Antibacterial Features on Cotton Fabric Colored with Novel Azo Compounds

Novel azo compounds were synthesized by diazotization of aniline and of 3-aminopyridine in the presence of NaNO2 and HCl, followed by coupling with 2-methylresorcinol in alkaline media. The structures were characterized using FT-IR, 1H NMR, and 13C NMR analysis. The main purpose of the present study is to investigate coloration applications, and antibacterial and fastness properties of the new azo structures in textile industry. Exhaust dyeing processes were applied on cotton fabric. Color strength ( K/ S values), L, a*, and b* values were measured. The color fastness values (to rubbing, light, perspiration, washing) of azo compounds on cotton fabric were presented according to ISO standards for comparison. Antibacterial activity assessment of the colored fabrics was performed according to AATCC 147-2016 test method against two types of bacteria: Staphylococcus aureus and Klebsiella pneumoniae. The fabric dyed with 2-methyl-4-[pyridin-3-yldiazenyl]benzene-1,3-diol demonstrated acceptable antibacterial activity against S. aureus.
