Heat and flame resistance of organic fiber is to use a wide range of large amount of fiber varieties. Type of fiber can be widely used for military supplies and equipment, protective products, filtration materials, electrical insulating materials, friction sealing material, a variety of industrial fabrics, high temperature paper and aerospace materials, weapons and equipment and other fields, to play in the national economy increasingly The more important role. In the international context, the high-temperature flame retardant fiber is an important class of strategic high-performance fiber materials, the countries in the world have an urgent need for high temperature flame retardant properties, green, and relatively inexpensive nature of flame retardant fiber. In 2007, organic fiber production of less than 4,000 tons of heat and flame resistance. The long-term use of high temperature above 250 ℃ fiber is scarce. Therefore, this type of fiber research, development, production, application worldwide has been mentioned in the national strategic level, while China has listed it as the "Eleventh Five-Year" period, and a longer period of time, the development of chemical fiber industry, the importance of directions.
Currently, several varieties of flame retardant high temperature fiber can be mass-produced very few, only aramid 1313, PSA, polyphenylene sulfide, and varying degrees of difficulties exist stain droplet, strength, burning generated when the flue gas and toxic, high prices, the performance has been unable to meet a variety of domestic demand, the quality can not compete with similar products, serious block the popularity of high-performance flame retardant products and upgrading.
High temperature flame retardant fiber is widely used in flame retardant combat uniforms, all types of spacesuits, the fire service, the police riot service, professional racing suits, petrochemical fireproof overalls, forest overalls and electrical service in many industries such as clothing, also hotel Textiles and lifesaving general civilian market channel, fire blankets, fire gloves, children's pajamas and bedding place, most protective products, filtration materials, electrical insulating materials, friction and sealing materials and other industrial fabric also requires a lot of The nature of high-temperature flame retardant fabric.
Currently, the lack of domestic market in low-cost, high-performance inherent fire blankets retardant fiber, moderate performance of medium-priced products mostly high cost little.
