PET/PP针刺非织造滤材制作工艺对其性能的影响分析

The Effect of Process Parameters to the Performance of PET/PP Needle Non-woven Filter Materials

以PET、PP纤维为原料,制得复合针刺非织造滤材,通过极差分析法及方差分析法分析了PET和PP的混合比、针刺速度及针刺频率对PET/PP复合针刺非织造滤材断裂强力、密度、厚度的影响。实验结果表明:在PET与PP混纺比为3∶7,针刺速度为23.12m/min,针刺频率为311.3Hz的情况下,PET/PP复合针刺非织造滤材综合性能达到最佳。在显著水平为0.1的条件下,混合比例对PET/PP复合针刺非织造滤材断裂强力有显著影响。

Taking PP, PET fibers as raw material, composite nonwoven filter fabric is manufactured in the needle machine by the orthogonal test method. And using the analysis of range and variance, the effect of mixing ratio, needling speed and density on breaking strength, density and thickness of PET/PP acupuncture composite nonwoven filter fabric is researched. The results show that the overall performance of PET/PP composite needle non-woven filter fabric is the best under the blend ratio of PET/PP 30 ： 70, acupuncture speed of 23.12 m/min, acupuncture frequency of 311.3 Hz. The blend ratio of PET/PP to the breaking strength has a significant effect in the significant level of 0.1.
