There are two major problems associated with the use of antibacterial cotton fabric. The durability of the fabric is poor, and the inherent properties of the fabric deteriorate following the execution of the finishing processes. These limit the application of antibacterial fabric. We first treated the cotton fabric with acryloyl chloride (AC) molecules to make the surface of the fabric rich in carbon‑carbon double (C=C) bonds. Following this, the [2-(methacryloyloxy)ethyl]dimethyl-(3-sulfopropyl)ammonium hydroxide (DMES) monomer was polymerized with the CC bonds on the fabric following the "grafting through" method. As a result, the cotton fabric was successfully grafted with the poly[2-(methacryloyloxy)ethyl]dimethyl-(3-sulfopropyl)ammonium hydroxide (PDMES), exploiting covalent bonds. The finished fabric exhibited excellent antibacterial effects. The bacterial reduction (BR) rates of the finished fabric against E. coli and S. aureus were greater than 99.0 %. Even after 50 washing cycles, the BR rates of the finished fabric against E. coli and S. aureus were greater than 96.0 %. In addition, the use of the "self-created" mist polymerization technology ensured that the inherent properties of the finished fabric were retained to a large extent. Therefore, the antibacterial cotton fabric prepared following this method can be potentially used for the fabrication of industrial and household textiles.
抗菌棉织物的使用存在两个主要问题。一是织物耐久性差,整理后其固有性能会恶化。二是这些限制了抗菌织物的应用。我们首先用丙烯酰氯(AC)分子处理棉织物,使织物表面富含碳-碳双键(C=C)。然后,通过“接枝穿过”法,用[2-(甲基丙烯酰氧)乙基]二甲基-(3-磺丙基)氢氧化铵(DMES)单体与织物上的 CC 键聚合。结果,棉织物成功地接枝了聚[2-(甲基丙烯酰氧)乙基]二甲基-(3-磺丙基)氢氧化铵(PDMES),利用了共价键。整理后的织物表现出优异的抗菌效果。整理后的织物对大肠杆菌和金黄色葡萄球菌的抑菌率大于 99.0%。即使经过 50 次洗涤循环,整理后的织物对大肠杆菌和金黄色葡萄球菌的抑菌率仍大于 96.0%。此外,使用“自创”雾化聚合技术确保了整理后织物的固有性能在很大程度上得以保留。因此,采用这种方法制备的抗菌棉织物可潜在用于工业和家用纺织品的制造。
