Flame retardant modification farinola-2 of polyacrylonitrile fibrous materials

The article presents the results of a flame-retardant modification of polyacrylonitrile fiber phosphate retarder burning pogonology-2. Modification of the newly formed, inlaid, fiber can increase by 8.5-10 % of the oxygen index. After repeated washings, the oxygen index remains high at 27-28 % vol, which enables to classify these materials as flammable. In this case, the strength and elongation of the fibers is reduced only by 3-6.5 %. DTA data allowed to establish the influence farinola-2 on thermal transformations that lead to the strengthening of the processes of cyclization and dehydrogenation, and consequently to carbonization, flameproof PAN fiber, thereby reducing its flammability.
