Abstract
High-strength polyvinyl alcohol fiber is provided by extruding a polyvinyl alcohol dope solution through a spinneret into a coagulating bath, the spinneret being located such that substantially only its dope-extruding surface contacts the coagulating bath. This process can produce stably and at a low cost polyvinyl alcohol fibers with excellent strength.
