A PROCESS FOR PREPARING POLYVINYLALCOHOL YARN WITH HIGH STRENGTH, AND POLYVINYLALCOHOL YARN PREPARED THEREFROM

摘要

The present invention relates to a method for producing a high strength polyvinyl alcohol fiber, and a high strength polyvinyl alcohol fiber produced therefrom, and more particularly, gelling by supplying cooling air during spinning of polyvinyl alcohol fiber and hot air heating stretching process It relates to a method for producing a high strength polyvinyl alcohol fiber comprising a, and a high strength polyvinyl alcohol fiber produced therefrom.;The method for producing polyvinyl alcohol fibers of the present invention enables uniform gel spinning during spinning of the polyvinyl alcohol fibers, and the polyvinyl alcohol fibers obtained therefrom have the advantage of improving tensile strength and elastic modulus.;Polyvinyl Alcohol, Fiber, Spinning, Air Gap, Hot Air, Stretching, Gelling
