苧麻(ma)(ma)(ma)纖(xian)(xian)維(wei)(wei)(wei)是一種性(xing)(xing)能(neng)(neng)(neng)優良的(de)(de)(de)紡(fang)織(zhi)纖(xian)(xian)維(wei)(wei)(wei),其(qi)織(zhi)物不(bu)(bu)僅吸濕(shi)(shi)(shi)散熱性(xing)(xing)好、透氣效(xiao)果極佳,而且具有(you)(you)挺括自然(ran)并(bing)(bing)且穿著舒適、涼(liang)爽等風(feng)格。國(guo)內(nei)麻(ma)(ma)(ma)紡(fang)廠一般主要采用(yong)濕(shi)(shi)(shi)法紡(fang)紗(sha)(sha)的(de)(de)(de)方(fang)法,而濕(shi)(shi)(shi)法紡(fang)紗(sha)(sha)工(gong)藝復雜(za),流程長,可紡(fang)支(zhi)數(shu)低,對(dui)設(she)備(bei)要求高(gao)(gao),濕(shi)(shi)(shi)法加(jia)(jia)工(gong)很難進行苧麻(ma)(ma)(ma)與其(qi)他纖(xian)(xian)維(wei)(wei)(wei)的(de)(de)(de)混紡(fang),且成紗(sha)(sha)僵(jiang)硬,難以(yi)(yi)開發高(gao)(gao)檔(dang)(dang)次(ci)、多品(pin)種的(de)(de)(de)紡(fang)織(zhi)產(chan)(chan)品(pin)。為克服上述缺陷(xian),能(neng)(neng)(neng)紡(fang)出高(gao)(gao)支(zhi)紗(sha)(sha)以(yi)(yi)提(ti)高(gao)(gao)產(chan)(chan)品(pin)檔(dang)(dang)次(ci),并(bing)(bing)使(shi)苧麻(ma)(ma)(ma)纖(xian)(xian)維(wei)(wei)(wei)的(de)(de)(de)生產(chan)(chan)大(da)范(fan)圍應運于針織(zhi)生產(chan)(chan),將(jiang)苧麻(ma)(ma)(ma)纖(xian)(xian)維(wei)(wei)(wei)與水(shui)(shui)(shui)溶纖(xian)(xian)維(wei)(wei)(wei)PVA混紡(fang),以(yi)(yi)干紡(fang)加(jia)(jia)工(gong)代替(ti)濕(shi)(shi)(shi)紡(fang)加(jia)(jia)工(gong),實現了苧麻(ma)(ma)(ma)純(chun)紡(fang)或與其(qi)他纖(xian)(xian)維(wei)(wei)(wei)混紡(fang)以(yi)(yi)擴大(da)產(chan)(chan)品(pin)范(fan)圍,并(bing)(bing)使(shi)其(qi)適應針織(zhi)加(jia)(jia)工(gong)。通過(guo)加(jia)(jia)入水(shui)(shui)(shui)溶纖(xian)(xian)維(wei)(wei)(wei)PVA,使(shi)其(qi)作為中(zhong)間(jian)纖(xian)(xian)維(wei)(wei)(wei)與麻(ma)(ma)(ma)纖(xian)(xian)維(wei)(wei)(wei)混紡(fang),利用(yong)PVA纖(xian)(xian)維(wei)(wei)(wei)所具有(you)(you)的(de)(de)(de)能(neng)(neng)(neng)溶于水(shui)(shui)(shui)的(de)(de)(de)獨特性(xing)(xing),通過(guo)水(shui)(shui)(shui)溶性(xing)(xing)維(wei)(wei)(wei)綸纖(xian)(xian)維(wei)(wei)(wei)(PVA)與苧麻(ma)(ma)(ma)伴紡(fang)再在(zai)后整理的(de)(de)(de)過(guo)程中(zhong)溶除(chu)PVA纖(xian)(xian)維(wei)(wei)(wei),不(bu)(bu)僅能(neng)(neng)(neng)使(shi)產(chan)(chan)品(pin)具有(you)(you)柔軟、輕薄等特性(xing)(xing),還可以(yi)(yi)降低生產(chan)(chan)成本(ben),提(ti)高(gao)(gao)企業(ye)的(de)(de)(de)經濟(ji)效(xiao)益。但含水(shui)(shui)(shui)溶PVA產(chan)(chan)品(pin)因(yin)其(qi)獨特的(de)(de)(de)工(gong)藝條(tiao)件使(shi)其(qi)在(zai)苧麻(ma)(ma)(ma)織(zhi)物后整理加(jia)(jia)工(gong)過(guo)程中(zhong)脫(tuo)除(chu)與常規產(chan)(chan)品(pin)相比技術難度大(da),單是對(dui)坯(pi)布通過(guo)高(gao)(gao)溫蒸煮處理,退維(wei)(wei)(wei)率(lv)也(ye)并(bing)(bing)不(bu)(bu)理想,坯(pi)布手(shou)感十分粗糙,麻(ma)(ma)(ma)織(zhi)物也(ye)體現不(bu)(bu)出其(qi)特有(you)(you)的(de)(de)(de)風(feng)格即“堅(jian)韌純(chun)潔,柔和(he)自然(ran),明亮美觀,端莊大(da)方(fang)”的(de)(de)(de)感覺。 這種技術既可以(yi)(yi)明顯降低生產(chan)(chan)中(zhong)的(de)(de)(de)用(yong)麻(ma)(ma)(ma)等級,又可以(yi)(yi)提(ti)高(gao)(gao)苧麻(ma)(ma)(ma)織(zhi)物的(de)(de)(de)檔(dang)(dang)次(ci)。并(bing)(bing)且操(cao)作簡單成本(ben)低廉,適合批量生產(chan)(chan)。

由于麻(ma)纖維(wei)可紡(fang)性差(cha),不易紡(fang)細(xi)號紗(sha)(sha)(sha),苧麻(ma)/水溶性維(wei)綸(lun)混紡(fang)紗(sha)(sha)(sha)織(zhi)(zhi)物(wu)經煮(zhu)漂(piao)后,水溶性維(wei)綸(lun)被溶解,混紡(fang)紗(sha)(sha)(sha)成(cheng)為細(xi)號純麻(ma)紗(sha)(sha)(sha),混紡(fang)紗(sha)(sha)(sha)織(zhi)(zhi)物(wu)成(cheng)為細(xi)號麻(ma)織(zhi)(zhi)物(wu).生產(chan)中漿紗(sha)(sha)(sha)工(gong)序是關(guan)鍵,經優選(xuan)漿料(liao)配方、漿紗(sha)(sha)(sha)工(gong)藝參(can)數及織(zhi)(zhi)造工(gong)藝參(can)數,保證了織(zhi)(zhi)造效率(lv)達(da)到(dao)70%左右,入庫一(yi)等品率(lv)達(da)到(dao)99.5%以上.
