Abstract
The effect of aluminum and some other metals on gelation in spinning solutions in production of the polyacrylonitrile fiber nitron-S was investigated. It was found that gelation in industrial spinning solutions is caused by the aluminum—iron electric pair contained in the filter press so that the aluminum lons formed cross-link the macromolecules of the acrylonitrile copolymers. It was shown that separation of the electric pair reduces gelation and consequently increases the stability of formation and improves the quality of the fiber.
