Due to the structure of hierarchical aligned cellulose fibrils, cotton fabric used in clothing possesses excellent moisture and thermal managements. Such structure yet may retain metabolic excrements and sebum secretions discharged from the human skin, which reproduce microorganisms harmful for human health. However, incorporating the antimicrobial coating into the cotton fabric can sufficiently resist the microorganism growth. In this work, a water-soluble antibacterial coating named N-(4-(allyloxy) benzylidene)-2-(piperazin-1-yl) ethanamine (NABPE) was synthesized to produce a rechargeable and fast sterilization cotton fiber fabric (M-cotton/NABPE). M-cotton/NABPE exhibited a high effective antibacterial activity, and the inhibition ratios against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) were 94 % and 93 %, respectively. Chlorination was performed with sodium hypochlorite solution to form N-Cl bond on the M-cotton/NABPE fabrics, resulting in a high biocidal efficacy of up to 100 % via contact killing for a duration of 5 min. After 25 washing cycles, the antibacterial fabric still maintained an antibacterial rate of 91.95 % and 92.15 % against E. coli and S. aureus, respectively. Furthermore, the fabrics showed integrated properties of excellent UV stability, long-term stability, robust rechargeable biocidal activity (chlorine recharging >5000 ppm) and washing durability. This research provides fundamental insights into the synthesis of the NABPE and prolonged biocidal efficacy of the M-cotton/NABPE, and thereby pave a pathway to incorporate an economic and environmental-friendly antibacterial coating suitable for finishing cotton fabric.

由于分层排列的纤维素原纤维的结构，用于服装的棉织物具有出色的水分和热管理。这种结构还可能保留人体皮肤排出的代谢排泄物和皮脂分泌物，从而繁殖对人体健康有害的微生物。然而，在棉织物中加入抗菌涂层可以充分抵抗微生物的生长。在这项工作中，合成了一种名为 N-(4-(烯丙氧基) 亚苄基)-2-(哌嗪-1-基) 乙胺 (NABPE) 的水溶性抗菌涂层，以生产可充电且快速杀菌的棉纤维织物 (M-棉/NABPE）。M-cotton/NABPE 表现出高效的抗菌活性，对大肠杆菌（E.coli）和金黄色葡萄球菌( S. aureus ) 分别为 94% 和 93%。用次氯酸钠溶液进行氯化，在 M-棉/NABPE 织物上形成 N-Cl 键，通过接触杀死 5 分钟，产生高达 100% 的高杀菌效力。经过25次洗涤循环后，抗菌面料对大肠杆菌和金黄色葡萄球菌仍保持91.95%和92.15%的抑菌率， 分别。此外，该织物显示出优异的紫外线稳定性、长期稳定性、强大的可充电杀菌活性（氯充电 >5000 ppm）和耐洗性等综合性能。这项研究为 NABPE 的合成和 M-cotton/NABPE 的延长杀菌功效提供了基本见解，从而为加入适用于整理棉织物的经济环保抗菌涂层铺平了道路。
