Recently, in order to improve the efficiency of the armor, we put much emphasis on the best bulletproof conditions, the lighter weight and the comfortableness. Due to the cumbersome and inflexible armors, users would feel inconvenient. Therefore, the main designing idea focuses on the comfortableness of armor wearing. Most of armor users are those policemen who have duties outside. When they wear armors outside on duty, they always perspire because of the time and working places. When sweating between the clothes and skin, the sweat could not come out because of the armor and then the wearer would feel uncomfortable. That forces the policemen refusing to use armor as a protection. So we worked on the outer layer textile of armor trying to improve the hygroscopic and permeable functions. By transmitting vapor through textile, sweat can be evaporated swiftly from the skin to the outside. After working on this research, we hope that policemen can feel more comfortable when they wear armors on duty and increase their working efficiency.
