摘　　要：利用管式炉将普通纯棉织物在850℃氮气保护下炭化,制得活性炭织物。通过显微镜观察织物表面结构,采用红外光谱对炭化棉纤维内部官能团进行表征,并对织物的蓄热升温性能、接触热传递性能和热传导系数进行测试分析。结果表明:炭化后织物表面结构完好,但纤维内部基团遭到破坏,织物强力很低;活性炭织物的蓄热升温速率明显高于棉织物,能够快速达到升温平衡,减少耗能;活性炭织物的瞬态热流量比棉织物低,接触热源过程中吸收的热量少,能降低能量损失;活性炭织物的热传系数比棉织物的低,和棉织物比较具有良好的隔热作用。The activated carbon fabric was prepared in a horizontal tube furnace by carbonizing ordinary cotton fabric under the protection of 850 ℃ nitrogen system. The surface structure of the fabric was observed by using the microscopy, and the infrared spectra was employed to characterize the functional group inside the carbonized cotton fibers. The thermal accumulation, contact heat transfer, and coefficient of thermal conductivity of the fabric were tested. After carbonization, the surface structure of the activated carbon fabric remained intact, but the groups inside the fiber were destroyed, the strength of the fabric reduced greatly; activated carbon fabric exhibited faster thermal accumulation and temperature rising than cotton fabric, quickly reaching the temperature balance and reducing energy consumption; activated carbon fabric showed lower transient heat flow than cotton, absorbed less heat in the process of contact with heat source and hence reduced the loss of energy; and activated carbon fabric has smaller heat transfer coefficient and better insulation than cotton fabric.
