Ammonium phytate and chitosan were chosen as eco-friendly flame retardants to improve the flame retardancy and antibacterial properties of viscose fabrics. The flame-retardant viscose fabrics exhibited sharp improvements in thermal stability at the higher temperature zone, and 2BLviscose retained 39.0% char residues at 700 °C. 2BL/viscose obtained a limiting oxygen index value of 29% and self-extinguished in the vertical flame test. The fire behaviors of the flame-retardant viscose fabrics were also enhanced; even the addition of CS decreased the total smoke production value from 0.6 to 0.3 m². Flame-retardant viscose fabrics released less flammable substances and more H₂O, resulting in combustion choking. Meanwhile, the flame-retardant samples formed stable char residues, which were mainly constituted by graphite. Meanwhile, the viscose fabrics coated with CS/AP exhibited excellent antimicrobial properties, and 2BL/viscose obtained a 99.99% antibacterial rate for both Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli).

选择植酸铵和壳聚糖作为环保型阻燃剂，以提高粘胶织物的阻燃和抗菌性能。阻燃粘胶织物在较高温度区的热稳定性显着提高，2BLviscose 在 700 °C 下保留了 39.0% 的焦炭残留物。2BL/粘胶获得29%的极限氧指数值，并在垂直火焰测试中自熄。阻燃粘胶织物的防火性能也得到了增强；即使添加 CS 也将总产烟值从 0.6 降低到 0.3 m ²。阻燃粘胶织物释放的易燃物质更少，H ₂释放更多O，导致燃烧窒息。同时，阻燃样品形成稳定的炭残留物，主要由石墨构成。同时，涂有CS/AP的粘胶织物表现出优异的抗菌性能，2BL/粘胶对金黄色葡萄球菌（S. aureus）和大肠杆菌（E.coli）的抗菌率均达到99.99% 。
