STUDIES ON THE EMULSION SPINNING

(II) PREPARATION OF POLYACRYLONITRILE EMULSIONS AND MIXED SPINNING WITH AQUEOUS SOLUTION OF POLYVINYL ALCOHOL

Abstract

Experiments were carried out for the preparation of polyacrylonitrile (PAN) emulsions using isopropyl alcohol as a regulator and anionic, cationic or nonionic surface active agent as an emulsifier Optimal conditions as emulsions for the mixed spinning were found. When the ratio PAN: PVA were 2:8 filaments could be spun most smoothly. The tenacity of the filaments were as high as that of the pure PVA filament.
