摘　　要：利用自行研制的铬酸处理液对超高相对分子质量聚乙烯(UHMWPE)纤维进行表面改性,并利用扫描电镜(SEM)、红外光谱(FITR)和接触角、单丝强力试验对纤维的表面性能和强度的变化进行表征。结果表明,表面处理时间和表面处理温度是影响纤维处理后性能的重要因素,UHMWPE纤维的最佳表面处理时间为3mim,最佳表面处理温度为80～85℃。The surface of ultra high molecular weight polyethylene （UHMWPE） fibers was modified by the eonfeeted chrome acid treatment solutions. The change of surface properties and strength of fibers were analyzed by Fourier transform spectrum （FTIR） , scanning electronic mierograph （SEM） , contact angle experiment, single fiber strength experiment. The results show that the surface disposal time and the surface disposal temperature are important factors to the properties of fibers. The optimal surface disposal time is 3 minutes and the optimal surface disposal temperature is 80-85℃
