Aramid fabric/fiber (AF), which possesses outstanding comprehensive qualities such as low density, high specific strength and high specific modulus, is widely used for body armor for defense. Different dyes and chemicals are required to give AF a specific coloration effect. AF is relatively difficult to dye due to its very crystalline structure and remarkable compactness. Different techniques, including supercritical carbon dioxide, microwave irradiation, liquid ammonia, ultraviolet treatment, copolymerization, high temperature, carrier method and ozone treatment, have already been utilized for the dyeing of AF. Some of these processes show excellent dyeing performance in terms of colorfastness against washing, rubbing and light. AF is also frequently used in harsh environments and cannot be cleaned in a timely manner. Bacteria that develop on its surface might pose a health concern, making AF with antibacterial properties extremely desirable. There have been a number of antibacterial treatments for AF to develop protection against Gram-positive and Gram-negative bacteria. The in situ treatment of AF using silver nanoparticles showed a high level of antibacterial activity. However, there are no reviews that discuss the coloration and antibacterial activity of AF. Therefore, this review summarizes the coloration and antibacterial activity of AF using different dyes and nanoparticles.

芳纶织物的着色和抗菌处理：全面综述

芳纶织物/纤维（AF）具有低密度、高比强度、高比模量等优异的综合品质，广泛应用于国防防弹衣。需要不同的染料和化学品才能赋予 AF 特定的着色效果。 AF 由于其非常结晶的结构和显着的致密性而相对难以染色。超临界二氧化碳、微波辐射、液氨、紫外线处理、共聚、高温、载体法和臭氧处理等不同技术已用于AF的染色。其中一些工艺在耐洗、耐摩擦和耐光色牢度方面表现出优异的染色性能。 AF也经常在恶劣环境下使用，无法及时清洁。其表面生长的细菌可能会造成健康问题，因此具有抗菌特性的 AF 非常理想。已有多种针对 AF 的抗菌治疗方法，以针对革兰氏阳性和革兰氏阴性细菌提供保护。使用银纳米颗粒对 AF 进行原位治疗显示出高水平的抗菌活性。然而，目前还没有讨论 AF 的显色和抗菌活性的评论。因此，本综述总结了使用不同染料和纳米颗粒的 AF 的显色和抗菌活性。
