摘要(Abstract)：

利用正交表安排试验,对超高相对分子质量聚乙烯(UHMWPE)纤维进行空气低温等离子体处理,测试各处理条件下UHMWPE纤维的力学和表面摩擦性能;采用矩阵分析法对多指标正交试验结果进行优化分析,找出最优方案并进行黏着性试验验证。结果表明:经空气低温等离子体处理后,UHMWPE纤维的断裂强度有所减小,表面静、动摩擦因数有较大幅度的提高;处理纤维的最优方案为功率50 W、压强15 Pa、时间150 s,此时纤维的断裂强度损失率仅为2.53%,剥离功为未处理时的4.25倍,说明由矩阵分析法得出的最优方案在保证纤维断裂强度损失很小的情况下,黏着性得到了很大程度的改善。
According to the orthogonal array, the air low temperature plasma was used to treat ultra-high molecular weight polyethylene(UHMWPE) fiber. The mechanical property and friction property in different conditions were tested. The matrix analysis was used to optimize the multi-target orthogonal test results,and the optimal conditions were found. Then, the adhesion property of UHMWPE fiber treated by the optimization condition was tested to verify the matrix analysis. The results showed that after treated by the air low temperature plasma, the breaking strength decreased, and the surface static and dynamic friction coefficients improved significantly. The optimum testing conditions were 50 W、15 Pa,150 s. Under the conditions, the breaking strength loss rate of the fibers was only 2.53%, and the stripping work was 4.25 times to the untreated fibers. These data showed that the optimum condition obtained by the matrix analysis had improved the adhesion to a great extent in ensuring the loss of fiber breaking strength was very small.
