【摘要】 阻燃是时下研究的一个热门问题,特别是纤维阻燃。卡拉胶具有优良的凝胶性能,采用湿法纺丝法将其制成纤维。用扫描电镜观察了卡拉胶纤维表面,结果显示纤维表面非常光滑,存在微量的金属离子盐;点燃实验表明卡拉胶纤维不燃烧,原因可能是由于纤维中含有大量金属离子,在燃烧过程中形成金属盐,阻碍纤维燃烧,扫面电镜观察纤维燃烧残留物,进一步验证阻燃机理与纤维中的金属离子有关。更多还原

【Abstract】 Flame material, especially flame-retardant fiber is a hot research focus nowadays. Carrageenan can be made into fibers by wet spinning because of its excellent properties of gelation. The surface of carrageenan fibers was observed by SEM, and the result shows that the fiber surface is very smooth, and there are trace amounts of metal ion salts on it. Experiment shows that carrageenan fibers do not ignite combustion, probably due to the large number of metal ions in the fibers. Metal ion salts formed in the combustion process, impede fibers combustion. So carrageenan fibers have excellent properties of flame. The combustion residues was studies by SEM, and the results verify that the flame retardancecy of carrageenan fibers is due to metal ions in the fiber.更多还原
