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(yi))低熔(rong)點粘合纖維

原則上講,凡(fan)是(shi)熔(rong)融法(fa)紡絲制成的合成纖(xian)維都(dou)可作(zuo)為熱熔(rong)粘合纖(xian)維而用于熱粘合法(fa)熱風棉生產中。但(dan)是(shi),有些纖(xian)維熔(rong)點(dian)太高(gao),如滌綸的熔(rong)點(dian)是(shi)285℃左(zuo)右,能耗(hao)太大,不適(shi)合用作(zuo)熱熔(rong)粘合纖(xian)維。

(二)超細纖維

超細纖(xian)(xian)維(wei)(wei)(wei)是指(zhi)纖(xian)(xian)維(wei)(wei)(wei)線密度為0.44dtex(0.4旦)以下的纖(xian)(xian)維(wei)(wei)(wei)。生(sheng)產方(fang)法(fa)主(zhu)要有兩(liang)種(zhong)(zhong)。一種(zhong)(zhong)方(fang)法(fa),是采(cai)用(yong)復合紡絲技術,先制得雙(shuang)組(zu)分(fen)(fen)復合纖(xian)(xian)維(wei)(wei)(wei),多為“海島型”或“桔瓣型”,。然后,再經溶(rong)解(jie)或分(fen)(fen)離(li)技術,使其中(zhong)的一種(zhong)(zhong)組(zu)分(fen)(fen)溶(rong)去或使雙(shuang)組(zu)分(fen)(fen)分(fen)(fen)離(li),即得超細纖(xian)(xian)維(wei)(wei)(wei)。

(三)高卷(juan)曲中空纖(xian)維

高(gao)卷曲(qu)(qu)中(zhong)(zhong)(zhong)(zhong)空滌(di)綸,以(yi)其高(gao)蓬松性和(he)保暖(nuan)性廣泛地用于(yu)非織(zhi)造保暖(nuan)絮片的(de)生產。它與普通滌(di)綸混合(he)可(ke)制造噴膠(jiao)棉、仿絲綿等。中(zhong)(zhong)(zhong)(zhong)空纖維(wei)(wei)(wei)的(de)品種很多(duo)。按卷曲(qu)(qu)特征(zheng),可(ke)分為(wei)(wei)二維(wei)(wei)(wei)卷曲(qu)(qu)和(he)三(san)維(wei)(wei)(wei)卷曲(qu)(qu)兩種。按組分的(de)多(duo)少,可(ke)分均一(yi)型中(zhong)(zhong)(zhong)(zhong)空纖維(wei)(wei)(wei),如滌(di)綸中(zhong)(zhong)(zhong)(zhong)空纖維(wei)(wei)(wei);雙組分復合(he)型中(zhong)(zhong)(zhong)(zhong)空纖維(wei)(wei)(wei),如滌(di)/丙復合(he)中(zhong)(zhong)(zhong)(zhong)空纖維(wei)(wei)(wei)。按中(zhong)(zhong)(zhong)(zhong)空孔(kong)數的(de)多(duo)少,可(ke)分為(wei)(wei)單(dan)孔(kong)和(he)多(duo)孔(kong)中(zhong)(zhong)(zhong)(zhong)空纖維(wei)(wei)(wei),如4孔(kong)、6孔(kong)和(he)9孔(kong)中(zhong)(zhong)(zhong)(zhong)空纖維(wei)(wei)(wei)。中(zhong)(zhong)(zhong)(zhong)空纖維(wei)(wei)(wei)的(de)中(zhong)(zhong)(zhong)(zhong)空度越(yue)大(da),滯留的(de)空氣量(liang)越(yue)多(duo)非織(zhi)造產品越(yue)輕便保暖(nuan)。

(四)絨毛(mao)漿纖維熱風棉(mian)

絨毛漿(jiang)纖(xian)維(wei)(wei)(wei),有時也稱木漿(jiang)纖(xian)維(wei)(wei)(wei),它是以原木為原料而制得的(de)天然纖(xian)維(wei)(wei)(wei)素(su)纖(xian)維(wei)(wei)(wei),屬于木漿(jiang)纖(xian)維(wei)(wei)(wei)的(de)一個品種(zhong)。絨毛漿(jiang)纖(xian)維(wei)(wei)(wei)中,纖(xian)維(wei)(wei)(wei)素(su)占(zhan)(zhan)(zhan)43%~45%,半纖(xian)維(wei)(wei)(wei)素(su)占(zhan)(zhan)(zhan)27%~30%,木質素(su)占(zhan)(zhan)(zhan)20%~28%,天然可提取物(wu)占(zhan)(zhan)(zhan)3%~5%。

(五)化學改(gai)性纖維(wei)

1有色(se)纖(xian)維(wei)

 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

針對化學纖維及其織物易產生靜電(dian)的(de)問題,國(guo)內外(wai)都進行了大(da)量的(de)研究和開發。一(yi)般認(ren)為(wei)纖維的(de)電(dian)阻率在(zai)100g·cm以(yi)下,具有良好的(de)抗靜電(dian)性能。

(六)高(gao)性(xing)能特種纖(xian)維

 一(yi)(yi)些具(ju)有高(gao)性能的(de)特種纖(xian)維(wei)(wei),如碳纖(xian)維(wei)(wei)、芳(fang)綸等,均用于非織(zhi)造布,如杜(du)邦公司的(de)凱夫拉( Kevlar)970芳(fang)綸纖(xian)維(wei)(wei),其強有力達13.2cN/dtex(15 gf/dtex)。另有一(yi)(yi)種名為 Carblnap的(de)100%碳纖(xian)維(wei)(wei)針刺法無紡布,可耐450℃高(gao)溫。
