摘　　要：采用化学接枝聚合技术对客舱用羊毛织物进行阻燃接枝改性,分别利用傅里叶变换红外光谱仪、X射线仪、极限氧指数测定仪、热分析仪等对接枝羊毛织物的结构和性能进行分析测试。结果表明:经阻燃接枝处理后,羊毛织物的燃烧性能大大提高,极限氧指数可以达到32%;通过红外光谱和X射线能谱分析可知,乙烯基单体接枝在纤维表面;通过扫描电子显微镜和原子力显微镜也可看出,单体与羊毛织物发生了反应;通过接枝前后羊毛织物的热重分析可知,经阻燃整理后羊毛织物的最大分解处温度降低了近25℃,而且裂解结束时接枝羊毛织物的残渣量远远高于未处理织物。In this experiment, a vinyl phosphorus-based monomer diethyl allylphosphonate （ DEAP） was applied onto wool fabrics by graft copolymerization technique.The structures and properties of the wool treated with vinyl phosphate were characterized by IR spectroscopy, X-ray, limited oxygen index and thermo-gravimetric.The results show that the flame retardancy of wool is greatly improved, and the LOI can reach 32%.The infrared spectrum analysis and X-ray energy spectrum analysis show that the vinyl monomer connects with the wool fabric.Through scanning electron microscope and atomic force microscope, it is shown that monomer and wool fabric had interaction.Thermal gravimetric analysis shows that after treated with vinyl monomer, the maximum decomposition temperature is reduced by 25 ℃ compared with the untreated wool fabric.In the end of decomposition, the char residue of grafted fabric is much more than that of untreated wool.
