單纖(xian)維測試(shi)儀(yi)(yi)是(shi)一(yi)種精密(mi)的(de)(de)(de)儀(yi)(yi)器，可在纖(xian)維干(gan)態(tai)或濕態(tai)下進(jin)行(xing)一(yi)次(ci)拉伸(shen)試(shi)驗，顯(xian)示強力、伸(shen)長率及定伸(shen)長負荷的(de)(de)(de)單值(zhi)(zhi)、平(ping)均值(zhi)(zhi)和(he)變異系(xi)數。所以(yi)對它的(de)(de)(de)要求(qiu)，企業也是(shi)非常的(de)(de)(de)高，因為(wei)這關(guan)系(xi)著最終的(de)(de)(de)質量，不(bu)過(guo)單個使(shi)用還不(bu)行(xing)，通(tong)過(guo)搭配(pei)棉檢驗，可以(yi)控(kong)制(zhi)好(hao)當中的(de)(de)(de)一(yi)些瑕(xia)疵，使(shi)其(qi)真正可以(yi)符合實際的(de)(de)(de)標準。

由于棉(mian)(mian)(mian)纖維(wei)大(da)容量(liang)(liang)測(ce)試(shi)(shi)儀僅涉及棉(mian)(mian)(mian)花(hua)的(de)長度、線密度、成(cheng)(cheng)熟度比、強力(li)、整齊(qi)度等，而棉(mian)(mian)(mian)花(hua)的(de)短(duan)絨率、成(cheng)(cheng)熟度百分比、未成(cheng)(cheng)熟纖維(wei)百分比、棉(mian)(mian)(mian)結、雜質等疵點(dian)(dian)的(de)測(ce)試(shi)(shi)都(dou)與(yu)紡(fang)紗的(de)要求(qiu)出入偏(pian)離較大(da)。 其與(yu)紡(fang)紗的(de)實(shi)際質量(liang)(liang)指(zhi)(zhi)標的(de)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)關(guan)聯性較小，與(yu)紡(fang)紗半制(zhi)(zhi)(zhi)品控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)的(de)梳棉(mian)(mian)(mian)條、精(jing)梳條的(de)質量(liang)(liang)指(zhi)(zhi)標無法建立(li)對應關(guan)系(xi)，使(shi)得(de)棉(mian)(mian)(mian)花(hua)測(ce)試(shi)(shi)指(zhi)(zhi)標與(yu)棉(mian)(mian)(mian)條質量(liang)(liang)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)指(zhi)(zhi)標難以形(xing)成(cheng)(cheng)對應控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)關(guan)系(xi)，所以建立(li)棉(mian)(mian)(mian)花(hua)混配棉(mian)(mian)(mian)單纖維(wei)測(ce)試(shi)(shi)儀質量(liang)(liang)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)指(zhi)(zhi)標，有利(li)于清梳聯工序危害性疵點(dian)(dian)的(de)清除和控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)，而且(qie)這(zhe)些(xie)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)指(zhi)(zhi)標都(dou)會對后工序梳棉(mian)(mian)(mian)條、精(jing)梳條的(de)控(kong)(kong)(kong)(kong)制(zhi)(zhi)(zhi)指(zhi)(zhi)標產生影響。

采用單纖(xian)維(wei)(wei)(wei)(wei)測(ce)(ce)試儀(yi)控制(zhi)優等棉(mian)(mian)花(hua)中的(de)(de)指(zhi)(zhi)標(biao)，制(zhi)定混配(pei)(pei)棉(mian)(mian)棉(mian)(mian)花(hua)單纖(xian)維(wei)(wei)(wei)(wei)測(ce)(ce)試物理指(zhi)(zhi)標(biao)控制(zhi)標(biao)準，尤其是對短纖(xian)維(wei)(wei)(wei)(wei)、未成熟纖(xian)維(wei)(wei)(wei)(wei)、棉(mian)(mian)結、帶(dai)纖(xian)維(wei)(wei)(wei)(wei)籽屑(xie)、雜(za)質、微塵的(de)(de)測(ce)(ce)試是提高(gao)清梳(shu)聯、精梳(shu)工序清除效率的(de)(de)關鍵，也是分析梳(shu)棉(mian)(mian)條(tiao)、精梳(shu)條(tiao)質量(liang)(liang)控制(zhi)指(zhi)(zhi)標(biao)與棉(mian)(mian)紗(sha)、面料細小紗(sha)疵控制(zhi)的(de)(de)關鍵，否則，單一的(de)(de)大容(rong)量(liang)(liang)纖(xian)維(wei)(wei)(wei)(wei)測(ce)(ce)試儀(yi)測(ce)(ce)試的(de)(de)棉(mian)(mian)花(hua)質量(liang)(liang)指(zhi)(zhi)標(biao)和混配(pei)(pei)棉(mian)(mian)指(zhi)(zhi)標(biao)對紡紗(sha)的(de)(de)指(zhi)(zhi)導就會出現較大的(de)(de)實際(ji)控制(zhi)偏(pian)差。
