High-temperature flame-retardant fiber is an important class of high-performance fiber materials. At present, all countries in the world are in urgent need of high-temperature flame-retardant fiber with good performance, green, and relatively inexpensive flame-retardant fibers. In 2007, China’s production of high-temperature flame-retardant fibers was less than 4,000 tons. The use of high-temperature flame-retardant fibers at temperatures above 250°C is scarce. Therefore, the research, development, production, and application of such high-temperature flame-retardant fibers have been referred to the national strategic level in the world, and China has listed it as a chemical fiber industry during the “11th Five-Year Plan” period and in the future. One of the important directions for development.
At present, there are only a few high-temperature flame-retardant fibers that can be mass-produced. Only a few varieties such as aramid 1313, aryl sulfone, and polyphenylene sulfide are available. Difficulty in dyeing, droplets, and poor strength occur in varying degrees. Flue gas and toxic, high price issues.
High-temperature flame-retardant fiber is widely used in flame-retardant combat clothing, various types of space suits, fire fighting clothing, racing suits, petrochemical fire protection work clothes, forest work clothes and many other industries of professional clothing, also applies to hotel textiles and life-saving channels, Fire blankets, and other civilian markets, the vast majority of protective products, filter materials, electrical insulation material, friction seal materials and other industrial fabrics also need a lot of high temperature flame retardant fiber.
