空气氛围下低温等离子体处理改善聚苯硫醚纤维表面性能的研究

设计正交试验,在空气氛围下,通过改变低温等离子体处理的时间、压强和功率三个条件参数,探寻影响聚苯硫醚纤维低温等离子体处理效果的主要因素,综合考虑各指标的变化情况,以纤维断裂强力下降不大,静、动摩擦系数和毛细管效应显著提高为目的,选择最理想的改性条件。利用综合平衡的数理统计方法优选改性条件,最后得到低温等离子体处理聚苯硫醚纤维的最佳工艺条件为:处理压强25Pa,处理功率180W,处理时间50s。

Research on surface modification of polyphenylene sulfide fiber by the low-temperature plasma treatment in the air atmosphere

Designed an orthogonal experiment and changed three parameters (i.e. time, pressure and power)of the low-temperature plasma treatment in the air atmosphere, polyphenylene sulfide fiber surface modification is made, then the main influencing factors of the fiber surface modification effect are found. Condsidered the changing of various indicators comprehensively, choosed the best modified condition that the breaking strength and the elongation at break do not decreased, static and dynamic coefficients of frictions increased significantly. Used the balanced of mathematical statistical method, found out the most appropriate modified condition. Finally, the best treatment process got as follows: processing pressure 25 Pa, processing power 180 W, processing time 50 s.
