| Abstract: | The effect of drawing process to the properties of UHMW PET was studied in this paper.Drawing speed and drawing temperature have remarkable effect on the properties of the first step drawn fibers,which influence the draw ability at the second step drawing process.With the drawing temperature and drawing speed decreasing,the drawing ratio of as spun fiber increases. |

| Keywords: | UHMW PET drawing speed drawing temperature orientation crystallinity |
