Conclusions
In modification of polyacrylonitrile fibres with alkali metal salts, a change in structure takes place, morphological nonuniformity in the transverse direction is increased, which aids in fibre crimping
Alkali metal salts interact with Nitron fibre both at the carboxyl groups of the polymer and also at its carbonyl groups.
