以聚苯硫醚(PPS)和聚丙烯(PP)為原料，采用熔融共混紡絲法制備PPS/PP共混海島纖維，經二甲苯溶除剝離掉基體相PP可制得PPS超細纖維。研究了PPS/PP共混組成、牽伸比對纖維的相結構、線密度、結晶、力學性能的影響。結果表明：PPS/PP共混組成比從30/70增加至 60/40時，PPS超細纖維平均直徑從228 nm 增至 408 nm；當PPS/PP共混組成比大于 60/40時，開始出現相轉變現象；PP的加入提高了PPS的結晶能力，隨著PPS/PP共混組成比增大，纖維線密度逐漸變大，共混纖維中PPS組分的結晶度變小，纖維力學性能降低；提高牽伸倍數，纖維線密度變小，斷裂強度增強，共混纖維中PPS組分的結晶度升高，紡速在280～350 m/min之間時，共混纖維可在2.0～3.0倍下進行牽伸；共混紡絲制得的PPS超細纖維熱穩定性有所下降，但并不影響PPS高溫使用性能。

The polyphenylene sulfide/polypropylene (PPS/PP) sea-island blend fibers were prepared from PPS and PP by blended melt spinning process. PPS superfine fibers were prepared by removing off PP matrix phase from the blend fiber in presence of xylene.The effect of composition ratio,drawing ratio on the phase structure,linear density,crystallization and mechanical properties of the blend fibers were studied.The results showed that the average diameter of PPS superfine fiber rose to 408nm from 228nm when the composition ratio of PPS/PP increased to 60/40 from 30/70.The phase transition began to appear when the composition ratio of PPS/PP more than 60/40.PP improved the crystallization ability of PPS, the fiber linear density became larger, the crystallinity of PPS and the mechanical properties of fibers was decreased, with the PPS/PP blend composition ratio increased.The fiber linear density became small,the fracture strength of fiber reinforced,crystallinity of PPS increased,with the drawing ratio improved.The drawing ratio of PPS/PP blend fiber was 2.0 to 3.0 times when the spinning speed was between in 280 and 350 m/min.The thermal stability of PPS superfine fiber declined, but that did not affect the high temperature properties of PPS.
