單(dan)纖維測試(shi)儀是一(yi)種精密的(de)(de)儀器，可(ke)在纖維干態或濕態下(xia)進(jin)行一(yi)次拉伸試(shi)驗，顯示強力、伸長(chang)率及定伸長(chang)負(fu)荷的(de)(de)單(dan)值、平均值和變異(yi)系(xi)數。所以(yi)(yi)對它(ta)的(de)(de)要求，企業也是非(fei)常的(de)(de)高，因為(wei)這關系(xi)著最終的(de)(de)質量，不過(guo)單(dan)個(ge)使用(yong)還不行，通過(guo)搭配棉檢(jian)驗，可(ke)以(yi)(yi)控制好當中的(de)(de)一(yi)些瑕疵(ci)，使其(qi)真(zhen)正可(ke)以(yi)(yi)符合實際的(de)(de)標準。

由于(yu)(yu)棉(mian)(mian)(mian)(mian)(mian)纖維(wei)大(da)容量(liang)測(ce)試(shi)儀(yi)僅涉及(ji)棉(mian)(mian)(mian)(mian)(mian)花(hua)的(de)(de)(de)(de)長度(du)(du)(du)、線密(mi)度(du)(du)(du)、成熟度(du)(du)(du)比(bi)、強力、整齊度(du)(du)(du)等，而(er)棉(mian)(mian)(mian)(mian)(mian)花(hua)的(de)(de)(de)(de)短絨率、成熟度(du)(du)(du)百(bai)分比(bi)、未(wei)成熟纖維(wei)百(bai)分比(bi)、棉(mian)(mian)(mian)(mian)(mian)結、雜質(zhi)等疵點(dian)的(de)(de)(de)(de)測(ce)試(shi)都與(yu)(yu)紡紗的(de)(de)(de)(de)要求出入偏(pian)離(li)較大(da)。 其與(yu)(yu)紡紗的(de)(de)(de)(de)實際質(zhi)量(liang)指(zhi)(zhi)(zhi)標(biao)的(de)(de)(de)(de)控(kong)制(zhi)(zhi)(zhi)關聯性(xing)較小，與(yu)(yu)紡紗半制(zhi)(zhi)(zhi)品控(kong)制(zhi)(zhi)(zhi)的(de)(de)(de)(de)梳棉(mian)(mian)(mian)(mian)(mian)條、精梳條的(de)(de)(de)(de)質(zhi)量(liang)指(zhi)(zhi)(zhi)標(biao)無(wu)法建立對(dui)應關系，使得(de)棉(mian)(mian)(mian)(mian)(mian)花(hua)測(ce)試(shi)指(zhi)(zhi)(zhi)標(biao)與(yu)(yu)棉(mian)(mian)(mian)(mian)(mian)條質(zhi)量(liang)控(kong)制(zhi)(zhi)(zhi)指(zhi)(zhi)(zhi)標(biao)難以(yi)形成對(dui)應控(kong)制(zhi)(zhi)(zhi)關系，所以(yi)建立棉(mian)(mian)(mian)(mian)(mian)花(hua)混(hun)配棉(mian)(mian)(mian)(mian)(mian)單(dan)纖維(wei)測(ce)試(shi)儀(yi)質(zhi)量(liang)控(kong)制(zhi)(zhi)(zhi)指(zhi)(zhi)(zhi)標(biao)，有利于(yu)(yu)清梳聯工序危害性(xing)疵點(dian)的(de)(de)(de)(de)清除(chu)和控(kong)制(zhi)(zhi)(zhi)，而(er)且這些控(kong)制(zhi)(zhi)(zhi)指(zhi)(zhi)(zhi)標(biao)都會對(dui)后(hou)工序梳棉(mian)(mian)(mian)(mian)(mian)條、精梳條的(de)(de)(de)(de)控(kong)制(zhi)(zhi)(zhi)指(zhi)(zhi)(zhi)標(biao)產生影響。

采用單(dan)(dan)纖(xian)(xian)維測(ce)(ce)試儀控制(zhi)(zhi)(zhi)優等棉花(hua)中的(de)指標(biao)(biao)，制(zhi)(zhi)(zhi)定混配棉棉花(hua)單(dan)(dan)纖(xian)(xian)維測(ce)(ce)試物理(li)指標(biao)(biao)控制(zhi)(zhi)(zhi)標(biao)(biao)準，尤其是對短纖(xian)(xian)維、未成熟(shu)纖(xian)(xian)維、棉結(jie)、帶纖(xian)(xian)維籽屑、雜質(zhi)、微塵的(de)測(ce)(ce)試是提高(gao)清梳聯、精梳工(gong)序清除效率的(de)關鍵(jian)(jian)，也是分(fen)析(xi)梳棉條、精梳條質(zhi)量控制(zhi)(zhi)(zhi)指標(biao)(biao)與棉紗(sha)(sha)、面料(liao)細小紗(sha)(sha)疵控制(zhi)(zhi)(zhi)的(de)關鍵(jian)(jian)，否則，單(dan)(dan)一的(de)大(da)容量纖(xian)(xian)維測(ce)(ce)試儀測(ce)(ce)試的(de)棉花(hua)質(zhi)量指標(biao)(biao)和混配棉指標(biao)(biao)對紡紗(sha)(sha)的(de)指導就會出現較大(da)的(de)實(shi)際控制(zhi)(zhi)(zhi)偏差。
