防(fang)(fang)靜(jing)(jing)電(dian)(dian)工作制(zhi)(zhi)伏是指為(wei)防(fang)(fang)止服(fu)裝上的(de)靜(jing)(jing)電(dian)(dian)聚集，用(yong)防(fang)(fang)靜(jing)(jing)電(dian)(dian)織物為(wei)面(mian)料而縫制(zhi)(zhi)的(de)制(zhi)(zhi)伏。

防(fang)(fang)靜電(dian)(dian)(dian)(dian)織(zhi)物(wu)是(shi)在(zai)紡(fang)織(zhi)時，大(da)體上等間(jian)隔(ge)地或均(jun)勻地混(hun)(hun)入導(dao)(dao)電(dian)(dian)(dian)(dian)纖(xian)(xian)維(wei)(wei)(wei)(wei)(wei)或防(fang)(fang)靜電(dian)(dian)(dian)(dian)合(he)成纖(xian)(xian)維(wei)(wei)(wei)(wei)(wei)或兩者(zhe)混(hun)(hun)合(he)錯(cuo)綜復(fu)雜而成的織(zhi)物(wu)。導(dao)(dao)電(dian)(dian)(dian)(dian)纖(xian)(xian)維(wei)(wei)(wei)(wei)(wei)是(shi)指(zhi)全(quan)部(bu)(bu)(bu)或部(bu)(bu)(bu)分(fen)使(shi)用(yong)金屬或有機化合(he)物(wu)的導(dao)(dao)電(dian)(dian)(dian)(dian)材(cai)料或亞(ya)導(dao)(dao)電(dian)(dian)(dian)(dian)材(cai)料制成的纖(xian)(xian)維(wei)(wei)(wei)(wei)(wei)的總稱，其(qi)體積電(dian)(dian)(dian)(dian)阻率ρv～介于104～109Ω/cm之(zhi)間(jian)。接照導(dao)(dao)電(dian)(dian)(dian)(dian)部(bu)(bu)(bu)分(fen)在(zai)纖(xian)(xian)維(wei)(wei)(wei)(wei)(wei)中的分(fen)散情形(xing)又可將導(dao)(dao)電(dian)(dian)(dian)(dian)纖(xian)(xian)維(wei)(wei)(wei)(wei)(wei)分(fen)為導(dao)(dao)電(dian)(dian)(dian)(dian)部(bu)(bu)(bu)分(fen)均(jun)一型(xing)、導(dao)(dao)電(dian)(dian)(dian)(dian)部(bu)(bu)(bu)分(fen)覆蓋(gai)型(xing)和導(dao)(dao)電(dian)(dian)(dian)(dian)部(bu)(bu)(bu)分(fen)復(fu)合(he)型(xing)3類(lei)。目前，絕大(da)多數防(fang)(fang)靜電(dian)(dian)(dian)(dian)織(zhi)物(wu)是(shi)采用(yong)導(dao)(dao)電(dian)(dian)(dian)(dian)纖(xian)(xian)維(wei)(wei)(wei)(wei)(wei)制作的，其(qi)中尤以導(dao)(dao)電(dian)(dian)(dian)(dian)部(bu)(bu)(bu)分(fen)復(fu)合(he)型(xing)，即復(fu)合(he)纖(xian)(xian)維(wei)(wei)(wei)(wei)(wei)使(shi)用(yong)最多。

在化學(xue)纖(xian)維(wei)(wei)織(zhi)物中(zhong)加入導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纖(xian)維(wei)(wei)制成的(de)(de)(de)(de)防靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)工作(zuo)制伏，其消電(dian)(dian)(dian)(dian)(dian)(dian)(dian)是基于(yu)(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)荷(he)的(de)(de)(de)(de)漏(lou)出(chu)與中(zhong)和兩種機理(li)。當(dang)保(bao)護(hu)接地時，織(zhi)物上的(de)(de)(de)(de)靜電(dian)(dian)(dian)(dian)(dian)(dian)(dian)除因導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纖(xian)維(wei)(wei)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)被中(zhong)和之外，還(huan)可經由導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纖(xian)維(wei)(wei)向大(da)地泄放(fang);不(bu)保(bao)護(hu)接地時則(ze)憑借于(yu)(yu)導(dao)(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纖(xian)維(wei)(wei)微弱的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)暈放(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)而消電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。

社會實(shi)踐(jian)表(biao)明，防靜(jing)(jing)電(dian)(dian)工(gong)作(zuo)(zuo)制伏可有(you)效(xiao)地抑(yi)止服裝(zhuang)靜(jing)(jing)電(dian)(dian)，消除(chu)或減小靜(jing)(jing)電(dian)(dian)放(fang)電(dian)(dian)損(sun)(sun)害。人(ren)體在(zai)進行各種運(yun)動時服裝(zhuang)上的(de)靜(jing)(jing)電(dian)(dian)勢差值(zhi)已大(da)(da)大(da)(da)超過許多靜(jing)(jing)電(dian)(dian)敏感(gan)器件的(de)靜(jing)(jing)電(dian)(dian)放(fang)電(dian)(dian)損(sun)(sun)壞(huai)閾值(zhi)，那末在(zai)觸(chu)及或接近(jin)這些元器件時就有(you)能夠造成敏感(gan)器件損(sun)(sun)壞(huai)。還需(xu)指出，一(yi)樣認為穿(chuan)純(chun)棉工(gong)作(zuo)(zuo)制伏可防止服裝(zhuang)靜(jing)(jing)電(dian)(dian)聚集，因而(er)就安全。實(shi)際這種看法具有(you)單方面性，只有(you)在(zai)空中(zhong)氣對立濕(shi)度高(gao)于50%時才(cai)根本如此;而(er)當對立濕(shi)度對照(zhao)低(di)時，純(chun)棉制品(pin)的(de)帶電(dian)(dian)量明顯增大(da)(da)。

試(shi)驗表明，在對立濕度(du)低(di)于(yu)30%時，純(chun)棉(mian)織物的(de)(de)帶電(dian)量與(yu)的(de)(de)確(que)良(liang)合適;而當(dang)對立濕度(du)低(di)于(yu)20%時，棉(mian)織物的(de)(de)帶電(dian)量甚至會高(gao)于(yu)某(mou)些(xie)化學(xue)纖維織物。所以(yi)在氣候干燥(zao)地域，不能期(qi)待在任何情(qing)形下都能用純(chun)棉(mian)制(zhi)品消除服裝(zhuang)靜(jing)電(dian)損害。基于(yu)以(yi)上原由，為有(you)效防(fang)止(zhi)人體靜(jing)電(dian)的(de)(de)靜(jing)電(dian)放電(dian)損害，操作者必須穿用防(fang)靜(jing)電(dian)工(gong)作制(zhi)伏(fu)。
