摘　　要：采用不同的热轧压力和温度,对自制的聚苯硫醚(PPS)熔喷非织造布进行热轧处理,研究不同热轧条件对PPS熔喷非织造布性能的影响。结果表明,提高热轧压力或温度,可使PPS熔喷非织造布的拉伸性能有所提高;当热轧压力为50.0 MPa、热轧温度为85℃时,PPS熔喷非织造布的拉伸性能最佳,其拉伸强度达到29.4 MPa;当热轧压力为50.0 MPa、热轧温度为50℃时,PPS熔喷非织造布的透气率和拉伸性能均较好。此外,在热轧压力10.0~50.0 MPa、热轧温度25~120℃条件下处理的PPS熔喷非织造布,其表面的水接触角可在72°~155°之间变化,即改变热轧条件可以调控PPS熔喷非织造布的亲水性。With different pressures and temperatures, the polyphenylene sulfide （PPS） melt blown nonwovens were prepared and treated by hot rolling. The effect of hot rolling condition on the properties of PPS melt blown nonwovens was studied. The results showed that the tensile properties of PPS melt blown nonwovens could be improved by the higher hot rolling pressure or temperature. The PPS melt blown nonwovens possessed the best tensile properties under the hot rolling pressure of 50.0 MPa and the hot rolling temperature of 85 ℃, with a tensile tenacity of 29.4 MPa. The airpermeability and the tensile properties of the PPS melt blown nonwovens were both better under the hot rolling pressure of 50.0 MPa and the hot rolling temperature of 50 ℃. In addition, the water contact angle of the PPS melt blown nonwovens treatedunder the hot rolling pressure of 10.0 - 50.0 MPa and the hot rolling temperature of 25 - 120 ℃ changed in the range of 72°-155°, which meaned that the hydrophilicity of the PPS melt blown nonwovens could be regulated by changing the hot rolling condition.
