單(dan)(dan)纖維測試儀是(shi)一(yi)(yi)(yi)種精密的(de)(de)儀器，可(ke)在纖維干態或濕態下進行一(yi)(yi)(yi)次拉(la)伸試驗，顯示強力、伸長(chang)(chang)率及定伸長(chang)(chang)負荷(he)的(de)(de)單(dan)(dan)值、平均值和(he)變異系(xi)數。所以(yi)對(dui)它的(de)(de)要求(qiu)，企業也是(shi)非常的(de)(de)高，因(yin)為這關系(xi)著(zhu)最終(zhong)的(de)(de)質量，不過(guo)單(dan)(dan)個使用還不行，通過(guo)搭配棉檢驗，可(ke)以(yi)控制好(hao)當中的(de)(de)一(yi)(yi)(yi)些瑕(xia)疵，使其真正可(ke)以(yi)符(fu)合實際(ji)的(de)(de)標準(zhun)。

由于棉(mian)(mian)(mian)(mian)(mian)纖維大(da)容(rong)量(liang)(liang)測試(shi)(shi)儀(yi)僅涉及棉(mian)(mian)(mian)(mian)(mian)花的長(chang)度(du)、線密(mi)度(du)、成熟(shu)度(du)比、強力、整齊度(du)等，而(er)棉(mian)(mian)(mian)(mian)(mian)花的短絨率、成熟(shu)度(du)百分(fen)比、未成熟(shu)纖維百分(fen)比、棉(mian)(mian)(mian)(mian)(mian)結(jie)、雜質(zhi)(zhi)等疵(ci)點的測試(shi)(shi)都與(yu)紡(fang)紗(sha)(sha)的要求出(chu)入(ru)偏離較大(da)。 其(qi)與(yu)紡(fang)紗(sha)(sha)的實際(ji)質(zhi)(zhi)量(liang)(liang)指(zhi)(zhi)標的控(kong)(kong)制(zhi)關聯性較小(xiao)，與(yu)紡(fang)紗(sha)(sha)半制(zhi)品控(kong)(kong)制(zhi)的梳(shu)棉(mian)(mian)(mian)(mian)(mian)條、精梳(shu)條的質(zhi)(zhi)量(liang)(liang)指(zhi)(zhi)標無法建(jian)立(li)對應關系，使(shi)得(de)棉(mian)(mian)(mian)(mian)(mian)花測試(shi)(shi)指(zhi)(zhi)標與(yu)棉(mian)(mian)(mian)(mian)(mian)條質(zhi)(zhi)量(liang)(liang)控(kong)(kong)制(zhi)指(zhi)(zhi)標難以(yi)形成對應控(kong)(kong)制(zhi)關系，所(suo)以(yi)建(jian)立(li)棉(mian)(mian)(mian)(mian)(mian)花混配棉(mian)(mian)(mian)(mian)(mian)單纖維測試(shi)(shi)儀(yi)質(zhi)(zhi)量(liang)(liang)控(kong)(kong)制(zhi)指(zhi)(zhi)標，有利(li)于清(qing)梳(shu)聯工序危害(hai)性疵(ci)點的清(qing)除和控(kong)(kong)制(zhi)，而(er)且這些控(kong)(kong)制(zhi)指(zhi)(zhi)標都會對后工序梳(shu)棉(mian)(mian)(mian)(mian)(mian)條、精梳(shu)條的控(kong)(kong)制(zhi)指(zhi)(zhi)標產生(sheng)影響(xiang)。
