Abstract (en)
Described is the spinning of a boric acid-containing aqueous polyvinyl alcohol solution in an alkaline coagulation bath. The coagulation bath is maintained at a temperature of 55 to 95 DEG C. The resulting tow of monofilaments is drawn in a draw ratio of not less than 17. This process provides polyvinyl alcohol-based synthetic fibers having a slender cross-sectional configuration and superior mechanical properties. By using these fibers as a reinforcement material for synthetic resins, rubbers, hydraulic inorganic materials, etc., there can be obtained shaped articles possessing improved mechanical properties.
