An increase in textile resistance to antimicrobial agents has posed a pressing need for the development of new antimicrobials. Therefore, the antimicrobial characteristics of thiophene and pyridine acetohydrazide derivatives have been developed as novel textile-modified complexes exhibiting antibacterial agents. Synthesis and characterization of pyridyl-thienyl acetohydrazide derivative (AHZ) using NMR (C and H) and FTIR. Modification of cotton fabric (CF) with acetohydrazide (AHZ) and metal chlorides of divalent Cr, Mn, Co, Ni, Cu, and Zn and trivalent Fe, and Cr. SEM-EDX and Fourier-transform infrared were utilized to characterize cellulose-based cotton fabric (CF) attached to AHZ and their metal (M) complexes. Antimicrobial activity was examined against two types of bacteria, namely and , and two types of fungi, namely and . All modified samples exhibited higher efficiency towards bacterial strains than fungal strains. In addition, cellulose modified with Ni (II) confers the most antibacterial protection efficiency.
纺织品对抗菌剂的抗性增加，迫切需要开发新型抗菌剂。因此，噻吩和吡啶乙酰肼衍生物的抗菌特性已被开发为具有抗菌剂特性的新型纺织品改性配合物。使用核磁共振（碳谱和氢谱）和傅里叶变换红外光谱对吡啶基 - 噻吩基乙酰肼衍生物（AHZ）进行合成与表征。用乙酰肼（AHZ）以及二价铬、锰、钴、镍、铜和锌的金属氯化物和三价铁及铬对棉织物（CF）进行改性。利用扫描电子显微镜 - 能谱仪（SEM - EDX）和傅里叶变换红外光谱对附着有AHZ及其金属（M）配合物的纤维素基棉织物（CF）进行表征。针对两种细菌，即[此处两种细菌名称缺失]和[此处两种细菌名称缺失]，以及两种真菌，即[此处两种真菌名称缺失]和[此处两种真菌名称缺失]，检测抗菌活性。所有改性样品对细菌菌株的效率均高于对真菌菌株的效率。此外，用镍（II）改性的纤维素具有最高的抗菌保护效率。
