為什么需要對熔噴布進(jin)行靜電駐極？實際上熔(rong)(rong)噴(pen)無紡布(bu)本身的(de)過(guo)(guo)濾(lv)(lv)(lv)性能(neng)很難達(da)到(dao)90%，而根據國家要(yao)求,一(yi)次性醫用口(kou)罩的(de)過(guo)(guo)濾(lv)(lv)(lv)效果率不能(neng)小(xiao)于95%，所(suo)以想要(yao)提(ti)高過(guo)(guo)濾(lv)(lv)(lv)效率還需(xu)要(yao)一(yi)個重(zhong)要(yao)的(de)工(gong)序：靜(jing)電(dian)(dian)駐極。（在沒(mei)(mei)有(you)加裝靜(jing)電(dian)(dian)駐極處理(li)機時(shi)(shi)，即使熔(rong)(rong)噴(pen)布(bu)過(guo)(guo)濾(lv)(lv)(lv)值達(da)到(dao)90%，也(ye)均(jun)視(shi)為不合(he)格，因為剛(gang) 生產出來的(de)熔(rong)(rong)噴(pen)布(bu)本身自身攜帶(dai)靜(jing)電(dian)(dian)，而這靜(jing)電(dian)(dian)一(yi)般保持(chi)在10-20天左右(you)就自然消失(shi)，沒(mei)(mei)有(you)攜帶(dai)靜(jing)電(dian)(dian)的(de)熔(rong)(rong)噴(pen)布(bu)也(ye)就喪失(shi)了熔(rong)(rong)噴(pen)布(bu)靜(jing)電(dian)(dian)吸附(fu)功能(neng)，做成口(kou)罩后單純靠纖維自身過(guo)(guo)濾(lv)(lv)(lv)是(shi)沒(mei)(mei)法有(you)效阻擋攜帶(dai)病毒的(de)分泌物或者(zhe)打(da)噴(pen)嚏時(shi)(shi)的(de)飛沫的(de)，這時(shi)(shi)候(hou)就體現出靜(jing)電(dian)(dian)駐極的(de)重(zhong)要(yao)性）其原(yuan)理(li)是(shi)通過(guo)(guo)靜電駐極處理機產生(sheng)的(de)(de)高壓直流電(dian)(dian)(dian)通過放電(dian)(dian)(dian)針對熔(rong)(rong)(rong)噴(pen)(pen)布(bu)(bu)(bu)進行充(chong)電(dian)(dian)(dian)（熔(rong)(rong)(rong)噴(pen)(pen)布(bu)(bu)(bu)原材料里需添(tian)加一定量的(de)(de)駐(zhu)極(ji)母(mu)粒，駐(zhu)極(ji)母(mu)粒其(qi)功能就(jiu)是可以(yi)(yi)(yi)把靜(jing)電(dian)(dian)(dian)儲存在熔(rong)(rong)(rong)噴(pen)(pen)布(bu)(bu)(bu)內），熔(rong)(rong)(rong)噴(pen)(pen)布(bu)(bu)(bu)捕(bu)獲針尖(jian)釋放出的(de)(de)電(dian)(dian)(dian)子后攜(xie)帶(dai)(dai)靜(jing)電(dian)(dian)(dian)，由于(yu)本身聚(ju)丙烯纖維的(de)(de)駐(zhu)極(ji)性（也就(jiu)是攜(xie)帶(dai)(dai)了駐(zhu)極(ji)母(mu)粒）它可以(yi)(yi)(yi)儲存電(dian)(dian)(dian)荷不流失，從(cong)(cong)而(er)不斷(duan)產生(sheng)靜(jing)電(dian)(dian)(dian)力，持續(xu)吸引空氣(qi)中(zhong)的(de)(de)帶(dai)(dai)電(dian)(dian)(dian)微粒，從(cong)(cong)而(er)捕(bu)獲病(bing)毒氣(qi)溶膠，這種方法能保證透(tou)氣(qi)性的(de)(de)同時顯著提高過濾(lv)效率，（當(dang)攜(xie)帶(dai)(dai)靜(jing)電(dian)(dian)(dian)的(de)(de)熔(rong)(rong)(rong)噴(pen)(pen)布(bu)(bu)(bu)做成口(kou)罩(zhao)以(yi)(yi)(yi)后，當(dang)遇到攜(xie)帶(dai)(dai)病(bing)毒的(de)(de)分泌物或者打噴(pen)(pen)嚏(ti)時的(de)(de)飛沫會被靜(jing)電(dian)(dian)(dian)吸附在口(kou)罩(zhao)無紡布(bu)(bu)(bu)表面，無法穿透(tou)）這就(jiu)是靜電駐極的重要性
