| Abstract: | POM fibers were prepared by melt spinning method with the adjustment of winding speed anddraw ratio of spinning.The influence of the thermal properties of POM resin,such as the crystallization andthermal decomposition,on the spinning process was analyzed by testing the orientation degree and thermaland mechanical properties of POM fibers.The effect of the spinning parameters on the performance of POMfiber was also studied.Meanwhile,the acid-base resistance of the POM fibers were analyzed.Resultsshowed that the most suitable spinning speed and draw ratio of POM fibers were 490 m/min and 7.4,respec-tively.POM fiber was found to have good resistance to weak acid and alkali. |
