[0002] At present, with the development of science and technology, the textile industry in our country has also developed rapidly. People have developed many new types of textiles. At the same time, the combustion problem of textiles is a matter of great concern to people, which is directly related to personal safety and fire protection. Textiles are in close contact with humans. Once burned, it will cause skin burns at least and endanger life at worst.
