【Abstract】 The polyphenylene sulfide/polypropylene(PPS/PP) sea-island blend fibers were prepared from PPS and PP by blend melt spinning process.PPS microfibers were prepared by removing PP matrix phase from the PPS /PP blend fiber in presence of xylene.Using scanning electron microscopy(SEM) to observe morphology of fibers,Thermal gravimetric(TG),X-ray diffraction(XRD) and Fourier transform infrared spectrometer(FTIR) to analyse the thermal properties and crystallization properties of PPS microfibers.The results showed that,the average diameter of PPS microfibers increased with the raising of PPS/PP composition ratio in a certain range.The thermal stability of PPS microfibers has decreased compared with pure PPS fiber,the initial decomposition temperature of PPS microfibers was 364 ℃,but it did not affect the performance of high temperature.The addition of PP improved the crystallization ability of PPS,which had no effect on the crystal type of PPS.更多还原
