| Abstract: | The aim of the test is to produce 20 cN/dtex PVA fiber and the investigation is made on wet spinning with the addition of boric acid. The feature of the spinning is adding boric acid and flux to the PVA solution with lower concentration, the fiber is solified in the alkaline solution. The extra high tensile strength PVA fiber is obtained through wet stretching and two stages of dry stretching. |

| Keywords: | PVA fiber extra high tenacity technological process boric acid multi-stage stretching |
