摘要:

为研究纤维表面油剂对针刺非织造材料驻极性能的影响,提高针刺非织造过滤材料的电晕驻极效果,以涤纶为原料,制备了不同面密度的涤纶针刺非织造材料,采用洗涤剂、碳酸钠以及乙醇试剂依次对非织造材料进行洗涤以去除纤维表面的油剂,分析试样在洗涤前后的介电常数、体积比电阻的变化,以及电晕驻极效果和效率衰减性能。结果表明:油剂的去除对涤纶针刺非织造材料的驻极效果有积极影响,去除油剂后其驻极性能大大提高;随着面密度增加,涤纶针刺非织造材料的驻极过滤性能差异更加明显,当面密度为250 g/ m2,经-15 kV 电压驻极处理1 min 后,其过滤效率由洗涤前的42. 6% 增加至洗涤后的57. 8%;油剂的去除使非织造材料的静电衰减周期延长。

Abstract:

In order to study the effect of the fiber surface oil on the charging performance of the needlepunched nonwoven materials, and improve the corona charging effect of the needle-punched nonwoven filter materials, polyester fiber was selected as raw material to prepare needle-punched nonwoven materials with different weights. The nonwoven materials were washed by detergent, sodium carbonate reagent and ethanol reagent to remove the oil on the fiber surface. The change of dielectric constant and volume specific resistance, as well as the corona charging effect and efficiency decay performance of the polyester nonwoven materials before and after washing was analyzed. The results show that the removal of the oil agent has a positive effect on the corona charging effect of the polyester needle-punched nonwoven material, and the charging performance of the nonwoven materials with oil removed has greatly improved. The difference of the charging filtration performance is more obvious when the weight is higher. After charging at -15 kV voltage for 1 min, the filtration efficiency of the needle-punched polyester nonwoven with the weight of 250 g/ m2 increases from 42. 6% to 57. 8% after washing. The removal of the oil agent lengthens the period of electrostatic decay of the polyester needle-punched nonwoven material.
