Abstract:	本研究係將融噴聚丙烯不織布加溫至玻璃轉位點以上，配合施加張力，由外部施加高壓靜電於布面，然後再將融噴眾丙烯不織布降至室溫，在此狀態下來評估不織布帶電性之效果，及對纖維外觀的影響。由實驗結果得知，靜電加工之融噴聚丙烯不織布表面靜電壓值隨著溫度、高壓靜電的上升而增加，但捲取速度增加反而呈現下降現象，而在纖維表面有熱熔、延伸和被電暈打擊留下凹陷或破洞的現象。 In this research, the polypropylene melt-blown nonwoven fabric is heated above the glass transition temperature point, and also set tension and high voltage static electricity at the surface of the nonwoven fabric. Then drop the temperature of the nonwoven fabric to the normal atmospheric temperature and evaluate the fiber of the effect of the static electrification and the external appearance. The results show that the static voltage of the surface of the polypropylene melt-blown nonwoven fabric be charged by the static electricity increased with the higher temperature, higher static voltage and higher take up tension, but decreased with higher take up speed. Otherwise, after all processes, the surface of the fiber will be melted or extended by the heat, and which will be struck by the corona discharge has hollows or holes.
