段彩紗廠家之環錠紡與氣流紡的差異

環錠(ding)(ding)紡紗(sha)(sha)是(shi)將(jiang)牽(qian)(qian)伸(shen)、加(jia)捻(nian)(nian)(nian)和(he)卷(juan)繞(rao)同時(shi)進行的(de)(de)一(yi)(yi)種紡紗(sha)(sha)方(fang)法，粗紗(sha)(sha)在(zai)牽(qian)(qian)伸(shen)系統中被(bei)牽(qian)(qian)伸(shen)至所(suo)要求紗(sha)(sha)支(zhi)的(de)(de)須(xu)條(tiao)，再經鋼領、鋼絲圈的(de)(de)加(jia)捻(nian)(nian)(nian)和(he)卷(juan)繞(rao)形成(cheng)(cheng)(cheng)一(yi)(yi)根(gen)紗(sha)(sha)線。由于牽(qian)(qian)伸(shen)作(zuo)用(yong)，主(zhu)牽(qian)(qian)伸(shen)區(qu)中的(de)(de)須(xu)條(tiao)寬度(du)(du)是(shi)所(suo)紡紗(sha)(sha)線直徑的(de)(de)數(shu)倍，此時(shi)各根(gen)纖(xian)(xian)(xian)維(wei)(wei)抵達(da)前鉗(qian)口線時(shi)呈自由狀態(tai)。當這(zhe)些(xie)纖(xian)(xian)(xian)維(wei)(wei)離(li)開(kai)前鉗(qian)口線后(hou)即被(bei)捻(nian)(nian)(nian)合(he)在(zai)一(yi)(yi)起(qi)，這(zhe)樣就形成(cheng)(cheng)(cheng)了一(yi)(yi)個紡紗(sha)(sha)加(jia)捻(nian)(nian)(nian)三(san)角區(qu)。此紡紗(sha)(sha)加(jia)捻(nian)(nian)(nian)三(san)角區(qu)阻止了邊(bian)緣纖(xian)(xian)(xian)維(wei)(wei)完全(quan)進入紗(sha)(sha)體(ti)，部(bu)分邊(bian)緣纖(xian)(xian)(xian)維(wei)(wei)脫離(li)主(zhu)體(ti)形成(cheng)(cheng)(cheng)飛(fei)花，較(jiao)多的(de)(de)邊(bian)緣纖(xian)(xian)(xian)維(wei)(wei)則是(shi)一(yi)(yi)端(duan)(duan)被(bei)捻(nian)(nian)(nian)入紗(sha)(sha)體(ti)，而(er)另(ling)一(yi)(yi)端(duan)(duan)形成(cheng)(cheng)(cheng)毛羽。這(zhe)些(xie)纖(xian)(xian)(xian)維(wei)(wei)不但(dan)對(dui)紗(sha)(sha)線的(de)(de)均勻度(du)(du)、彈(dan)性等(deng)性能起(qi)作(zuo)用(yong)，且(qie)對(dui)紗(sha)(sha)線的(de)(de)不利。另(ling)外(wai)，在(zai)加(jia)捻(nian)(nian)(nian)時(shi)處于三(san)角區(qu)外(wai)側的(de)(de)纖(xian)(xian)(xian)維(wei)(wei)受(shou)到的(de)(de)張力(li)較(jiao)大，而(er)在(zai)中心的(de)(de)纖(xian)(xian)(xian)維(wei)(wei)受(shou)到的(de)(de)張力(li)較(jiao)小，故成(cheng)(cheng)(cheng)紗(sha)(sha)時(shi)這(zhe)些(xie)纖(xian)(xian)(xian)維(wei)(wei)的(de)(de)初始張力(li)不等(deng)。這(zhe)些(xie)都是(shi)傳統環錠(ding)(ding)紡紡紗(sha)(sha)三(san)角區(qu)造成(cheng)(cheng)(cheng)的(de)(de)缺陷(xian)。

轉(zhuan)杯(bei)紡又稱氣流(liu)紡，屬于(yu)自由端紡紗(sha)(sha)方法。直接喂入紡紗(sha)(sha)器的(de)棉條經分(fen)梳(shu)輥分(fen)梳(shu)成了(le)單纖(xian)維狀，纖(xian)維*分(fen)梳(shu)輥的(de)離心力(li)和(he)紡杯(bei)內(nei)負壓氣流(liu)的(de)作用(yong)脫離分(fen)梳(shu)輥表面經輸棉管道而(er)進入紡杯(bei)，并在凝(ning)聚槽中形成一個完整的(de)纖(xian)維環，纖(xian)維環隨著紡杯(bei)高速旋(xuan)轉(zhuan)，在接頭紗(sha)(sha)的(de)作用(yong)下，隨著捻(nian)度(du)不(bu)斷的(de)傳遞和(he)連續(xu)剝(bo)離纖(xian)維束而(er)成紗(sha)(sha)。

氣流紡一般是紡低支紗，環錠紡多為紡高支紗環錠紡紗(ring spinning)，是現時市場上用量較多，通用之紡紗方法,條子或粗紗經牽伸后的纖維條 通過環錠鋼絲圈旋轉引入，筒管卷繞速度比鋼絲圈快，棉紗被加拈制成細紗
