| Abstract: | The DSC test showed that the melting temperature of polyoxymethylene(POM) was 170 ℃, andthen through experiments the optimal temperature for the preparation of POM fibers was found at 190 ℃.The effects of POM content and voltage on the diameter of fiber were studied, and the optimal conditions ofmelt electrospinning were the voltage 14 k V and the POM content 90%. The surface morphology and ther-mal properties of POM fibers were tested, and the results showed that the POM fibers were uniform andowned smooth surface, with high crystallinity of 68.84% and lower melting point of 160.25 ℃ than POM. |
