NOVEL NETWORK POLYAMIDE FIBERS BY REACTION SPINNING

Abstract

Polyamide fibers having a novel regular network structure were prepared from trimesoyl trichloride and hexamethylenediamine using a reaction spinning method followed by post-polymerization. Optimum conditions were investigated for the reaction spinning and the post-polymerization to obtain a fiber having good mechanical properties. The polyamide fibers prepared were insoluble in concentrated sulfuric acid and contained a lot of microscopic voids. The structure of the fibers obtained by the reaction spinning was slightly ordered by the post-polymerization and the fibers became thermally more stable.
