除塵配件之es熱風棉生產中常用的幾種差別化纖維，一起和口罩熱風棉廠家來了解下：

es熱風棉

一)低熔點粘合纖(xian)維

原則上講(jiang),凡是(shi)(shi)熔(rong)(rong)融(rong)法紡絲(si)制(zhi)成的合成纖維都可作為熱熔(rong)(rong)粘(zhan)(zhan)合纖維而用(yong)于熱粘(zhan)(zhan)合法熱風棉生產(chan)中。但是(shi)(shi),有些(xie)纖維熔(rong)(rong)點太高,如滌綸的熔(rong)(rong)點是(shi)(shi)285℃左右,能耗太大,不(bu)適合用(yong)作熱熔(rong)(rong)粘(zhan)(zhan)合纖維。

(二)超細纖維

超細纖維是(shi)指(zhi)纖維線(xian)密度為0.44dtex(0.4旦)以下的(de)纖維。生產方(fang)法主要有兩種。一(yi)種方(fang)法,是(shi)采用復合紡(fang)絲技術(shu),先制得(de)雙組(zu)分復合纖維,多為“海島型(xing)”或“桔瓣型(xing)”,。然后,再經溶解或分離技術(shu),使其中的(de)一(yi)種組(zu)分溶去或使雙組(zu)分分離,即(ji)得(de)超細纖維。

(三)高卷曲中空(kong)纖維(wei)

高卷曲(qu)中(zhong)(zhong)(zhong)(zhong)空(kong)(kong)滌(di)綸(lun)(lun),以其高蓬松性和(he)保暖(nuan)性廣泛(fan)地用于非(fei)織造保暖(nuan)絮(xu)片的(de)生(sheng)產(chan)。它(ta)與普通(tong)滌(di)綸(lun)(lun)混(hun)合(he)可制造噴膠(jiao)棉、仿絲綿等。中(zhong)(zhong)(zhong)(zhong)空(kong)(kong)纖(xian)維(wei)(wei)的(de)品種很多。按(an)卷曲(qu)特征(zheng),可分(fen)為(wei)二維(wei)(wei)卷曲(qu)和(he)三維(wei)(wei)卷曲(qu)兩種。按(an)組分(fen)的(de)多少(shao),可分(fen)均一(yi)型中(zhong)(zhong)(zhong)(zhong)空(kong)(kong)纖(xian)維(wei)(wei),如(ru)滌(di)綸(lun)(lun)中(zhong)(zhong)(zhong)(zhong)空(kong)(kong)纖(xian)維(wei)(wei);雙組分(fen)復(fu)合(he)型中(zhong)(zhong)(zhong)(zhong)空(kong)(kong)纖(xian)維(wei)(wei),如(ru)滌(di)/丙(bing)復(fu)合(he)中(zhong)(zhong)(zhong)(zhong)空(kong)(kong)纖(xian)維(wei)(wei)。按(an)中(zhong)(zhong)(zhong)(zhong)空(kong)(kong)孔(kong)(kong)數的(de)多少(shao),可分(fen)為(wei)單孔(kong)(kong)和(he)多孔(kong)(kong)中(zhong)(zhong)(zhong)(zhong)空(kong)(kong)纖(xian)維(wei)(wei),如(ru)4孔(kong)(kong)、6孔(kong)(kong)和(he)9孔(kong)(kong)中(zhong)(zhong)(zhong)(zhong)空(kong)(kong)纖(xian)維(wei)(wei)。中(zhong)(zhong)(zhong)(zhong)空(kong)(kong)纖(xian)維(wei)(wei)的(de)中(zhong)(zhong)(zhong)(zhong)空(kong)(kong)度越(yue)大(da),滯留(liu)的(de)空(kong)(kong)氣量越(yue)多非(fei)織造產(chan)品越(yue)輕便保暖(nuan)。

(四)絨毛漿纖維熱風棉

絨(rong)毛(mao)漿纖(xian)(xian)維(wei),有時也稱木漿纖(xian)(xian)維(wei),它是以原木為原料而制(zhi)得的(de)(de)天然纖(xian)(xian)維(wei)素(su)(su)纖(xian)(xian)維(wei),屬于木漿纖(xian)(xian)維(wei)的(de)(de)一個(ge)品種。絨(rong)毛(mao)漿纖(xian)(xian)維(wei)中,纖(xian)(xian)維(wei)素(su)(su)占(zhan)43%~45%,半(ban)纖(xian)(xian)維(wei)素(su)(su)占(zhan)27%~30%,木質素(su)(su)占(zhan)20%~28%,天然可提取物占(zhan)3%~5%。

(五)化(hua)學改(gai)性纖(xian)維(wei)

1有色(se)纖維

 有色纖維是通過添加色母粒的方法共混紡絲制得的,是差別化纖維中開發較早的品種。在干法熱風棉生產中,常用有色的粗旦丙綸或滌綸短纖維制造針刺地毯和針刺壁毯等。在紡粘法無紡布生產中,添加色母粒可直接紡制有色的非織造布,主要用于醫用衛生材料中的手術衣、帽等。

2.抗靜電纖維

針對(dui)化(hua)學纖維(wei)及其織物易產生靜電(dian)(dian)的問(wen)題,國內(nei)外都進行了大量的研究和開發。一般認為纖維(wei)的電(dian)(dian)阻率(lv)在(zai)100g·cm以下,具(ju)有良好的抗靜電(dian)(dian)性(xing)能。

(六)高性能特種纖維

 一些具有高(gao)性能(neng)的(de)特種(zhong)纖(xian)(xian)維,如碳(tan)纖(xian)(xian)維、芳(fang)綸等,均(jun)用于非織造布(bu),如杜(du)邦公司的(de)凱(kai)夫拉( Kevlar)970芳(fang)綸纖(xian)(xian)維,其強(qiang)有力達(da)13.2cN/dtex(15 gf/dtex)。另有一種(zhong)名為(wei) Carblnap的(de)100%碳(tan)纖(xian)(xian)維針(zhen)刺法(fa)無紡布(bu),可耐450℃高(gao)溫。
