Abstract
High strength and modulus fibers are prepared from a poly(vinyl alcohol) solution in a mixed solvent consisting of water and water-miscible organic solvent. Upon extruding the poly(vinyl alcohol) solution into a coagulation bath, gel fibers are formed as a consequence of favorable gel structure with homogeneous net-works. Drawing the gel fibers to an exceedingly high degree leads to formation of poly(vinyl alcohol) fibers which have a superhigh tensile strength and a superhigh modulus.
