The scientific name of polyester fiber is polyester, which is easy to ignite. It shrinks, melts and smokes when it is close to the flame. The flame is yellow and smells fragrant. After combustion, the ash is dark brown block, which can be twisted by fingers.
　　丙烯和聚丙烯丙烯的学名为聚丙烯腈纤维，靠近火软化融化后再冒烟，用大火烧成白色火焰，大火迅速燃烧后，散发出火种肉的苦味，燃烧后灰烬为不规则黑色块状，手捻易碎。聚丙烯的学名，聚丙烯纤维靠近火焰即收缩，易燃，燃烧缓慢而冒烟，火焰上部呈黄色，底部呈蓝色，散发出油烟味，燃烧后的灰烬如坚硬的小黄褐色颗粒，经手捻后易碎。
　　The scientific name of propylene and polypropylene propylene is polyacrylonitrile fiber. It softens and melts near the fire and then smokes. It burns into a white flame with a large fire. After the fire burns rapidly, it gives off the bitter taste of the fire meat. After the fire, the ashes are irregular black blocks, and the hands are fragile. Scientific name of polypropylene: polypropylene fiber shrinks when it is close to the flame. It is flammable. It burns slowly and smokes. The upper part of the flame is yellow and the bottom is blue. It gives off the smell of oil smoke. The ashes after burning are like small hard yellow brown particles, which are fragile after being twisted by hand.

　　学名whalen和氯纶whalen聚乙烯醇甲醛纤维，不容易点燃，近火焰熔融收缩，顶部有少许火焰，燃烧为纤维混合胶化火焰，有浓浓的黑烟，有苦甜的气味，燃烧后留下黑色小珠颗粒，可用手指压碎。学名氯纶PVC纤维，不易燃烧，远离火种即为扑灭，火焰呈黄色，底绿色白色冒烟，辛辣刺激酸涩，燃烧后灰烬为深褐色不规则块状，手指扭曲不易折断。
　　Its scientific name is Whalen and chloro fiber Whalen polyvinyl formal fiber, which is not easy to ignite. It is near the flame melting and contracting. There is a little flame on the top. The flame is a mixed gelatinized flame of fiber, with thick black smoke and bitter sweet smell. After burning, it leaves small black beads, which can be crushed by fingers. Its scientific name is PVC fiber, which is not easy to burn. If it is far away from the fire, it will be extinguished. The flame is yellow, with green and white smoke at the bottom. It is spicy and sour. After burning, the ash is dark brown irregular block, and the fingers are not easy to break.
　　氨纶和氟烷氨纶，又称聚氨基甲酸酯纤维，在火附近熔化和燃烧，火焰燃烧时呈蓝色，离开火继续熔化和燃烧，发出一种特殊的刺激性气味，燃烧后的灰烬是柔软而蓬松的黑色灰烬。
　　Spandex and halothane spandex, also known as polyurethane fiber, melt and burn near the fire. When the flame burns, it is blue, and continues to melt and burn away from the fire, giving out a special pungent smell. The ash after combustion is soft and fluffy black ash.
