Polyester fiber name is polyester fiber, easy to ignite, near the flame that melt shrinkage, burning when melting black smoke, a yellow flame, emitting aromatic odor, burned black brown hard lump, with fingers can be twisted.

Four, acrylic fiber and polypropylene acrylic fiber name polyacrylonitrile fiber, melted and melted near the fire, after burning black smoke, flame is white, from the flame quickly burning, emitting the bitterness of burning meat, burned ashes for irregular black hard block, hand twisting fragile. Polypropylene fiber is known as polypropylene fiber, which is near flame, which is melted and flammable. It is flammable. It burns slowly from the fire and smoked black.

Polytetrafluoroethylene (PTFE), known as fluorine fiber, is called fluorite fiber by ISO. It is only melting near flame. It is hard to ignite and burn. The edge flame is blue-green and carbonized and melted and decomposed. The gas is poisonous, and the melting material is hard round black bead. Fluorine fiber is commonly used in the textile industry to produce high-performance sewing thread.
