Parameters for Modifiying Polyacrylonitrile Fiber with Hybrid Modifiers

Resumo

The optimal parameters for modifying polyacrylonitrile (PAN) fiber to produce flame-resistant materials were established from kinetic absorption studies of the flame-retardant system components and the combustion indexes of the modified fibers. The absorption parameters were determined. The absorption of the flame-retardant systems by PAN fibers obeyed the Freundlich equation for the non-linear dependences of the flame-retardant concentrations on the fibers as a function of their bath concentrations.
