| Abstract: | This paper reports the effects of differemt spinning conditions and dissolution processes with different solvents on the properties of polyvinly alcohol fiber. A new process has been found to produce high strength, high modulus PVA fiber. The PVA of conventional molecular weight was dissolved in water with an addition of boric acid, then the fiber was spun by the dry-wet or wet method and finally processed by wet-hot and dry-hot drawing of multiple steps. The strngth of fiber obtained was as high as 11. 35 cN/dtex and its initial modulus was 364.0 cN/dtex. It is therefore, suited for the application in industry. |
