燒毛軋光后整(zheng)理對針刺非織造布性(xing)能(neng)的影響
燒毛軋光后(hou)(hou)(hou)整(zheng)(zheng)理(li)(li)(li)會對針(zhen)刺非(fei)織造材料的性(xing)(xing)能(neng)(neng)產(chan)生一定(ding)影響(xiang),研究后(hou)(hou)(hou)整(zheng)(zheng)理(li)(li)(li)工(gong)藝對材料性(xing)(xing)能(neng)(neng)的影響(xiang)有(you)利于優化(hua)工(gong)藝參數(shu),提高材料的綜合性(xing)(xing)能(neng)(neng).選取滌綸、玻璃纖(xian)維、聚苯硫醚(PPS)這3種(zhong)纖(xian)維原料的非(fei)織造布試(shi)樣(yang)(yang)進行燒毛和燒毛-軋光整(zheng)(zheng)理(li)(li)(li),并(bing)測試(shi)試(shi)樣(yang)(yang)的透(tou)氣性(xing)(xing)、強力、孔(kong)徑、過濾效(xiao)率(lv).研究結果表(biao)明:燒毛-軋光整(zheng)(zheng)理(li)(li)(li)后(hou)(hou)(hou)3種(zhong)試(shi)樣(yang)(yang)的透(tou)氣率(lv)分(fen)別下降了31.6%,8.3%和42.2%;整(zheng)(zheng)理(li)(li)(li)后(hou)(hou)(hou)試(shi)樣(yang)(yang)的孔(kong)徑上升較大,強力則(ze)變化(hua)不大,但過濾效(xiao)率(lv)達到了99.99%,從而可有(you)效(xiao)地過濾細小(xiao)顆粒.
針刺非(fei)織(zhi)(zhi)(zhi)造(zao)(zao)布(bu)(bu)由于其(qi)(qi)發展時間長、生產(chan)(chan)技(ji)術成熟、設備(bei)(bei)穩定(ding)性(xing)(xing)好(hao)、產(chan)(chan)品(pin)(pin)性(xing)(xing)能(neng)(neng)優良,目(mu)前在(zai)濾(lv)料市(shi)場占有(you)(you)較(jiao)大比(bi)重(zhong).由于濾(lv)料在(zai)實(shi)際過(guo)(guo)濾(lv)工況中環(huan)境(jing)苛刻復雜,市(shi)場對(dui)過(guo)(guo)濾(lv)產(chan)(chan)品(pin)(pin)的(de)差(cha)別化(hua)及功能(neng)(neng)化(hua)要(yao)求不斷提(ti)高.許(xu)多企(qi)業除通(tong)(tong)過(guo)(guo)改進工藝、引進先(xian)進設備(bei)(bei)以(yi)提(ti)高質量外(wai),還對(dui)非(fei)織(zhi)(zhi)(zhi)造(zao)(zao)布(bu)(bu)濾(lv)料進行后整(zheng)(zheng)理,以(yi)改變其(qi)(qi)絨毛(mao)結構,改善濾(lv)料的(de)空隙結構,提(ti)高產(chan)(chan)品(pin)(pin)質量.過(guo)(guo)濾(lv)用非(fei)織(zhi)(zhi)(zhi)造(zao)(zao)布(bu)(bu)的(de)常見后整(zheng)(zheng)理方法有(you)(you)很多,如燒毛(mao)、軋(ya)(ya)光、浸(jin)漬、涂(tu)層、覆膜、烘干、熱定(ding)型等,其(qi)(qi)中,燒毛(mao)和軋(ya)(ya)光對(dui)過(guo)(guo)濾(lv)用針刺非(fei)織(zhi)(zhi)(zhi)造(zao)(zao)布(bu)(bu)性(xing)(xing)能(neng)(neng)的(de)影響尤其(qi)(qi)顯(xian)著.經過(guo)(guo)燒毛(mao)處理可以(yi)減少(shao)濾(lv)材表面絨毛(mao),得到光滑亮潔的(de)布(bu)(bu)面;增加非(fei)織(zhi)(zhi)(zhi)造(zao)(zao)布(bu)(bu)濾(lv)材表面孔(kong)隙率(lv),有(you)(you)利于疏通(tong)(tong)濾(lv)材內部(bu)空氣(qi)通(tong)(tong)道,從而減小清灰(hui)時的(de)氣(qi)流壓(ya)力.軋(ya)(ya)光是將經過(guo)(guo)燒毛(mao)的(de)非(fei)織(zhi)(zhi)(zhi)造(zao)(zao)布(bu)(bu)平整(zheng)(zheng)地通(tong)(tong)過(guo)(guo)具有(you)(you)一定(ding)壓(ya)力的(de)上下軋(ya)(ya)輥,進一步提(ti)高其(qi)(qi)平整(zheng)(zheng)度.
