單纖(xian)維(wei)測(ce)試(shi)儀是一種(zhong)精(jing)密的(de)(de)儀器，可在纖(xian)維(wei)干態(tai)或(huo)濕(shi)態(tai)下進行(xing)一次拉伸(shen)試(shi)驗(yan)(yan)，顯(xian)示強(qiang)力(li)、伸(shen)長(chang)率及定(ding)伸(shen)長(chang)負荷的(de)(de)單值、平均值和變異(yi)系(xi)(xi)數。所以對它的(de)(de)要求(qiu)，企業也(ye)是非常的(de)(de)高，因為這關系(xi)(xi)著最終的(de)(de)質量，不過(guo)單個使(shi)用(yong)還(huan)不行(xing)，通過(guo)搭配棉檢驗(yan)(yan)，可以控制好當中的(de)(de)一些瑕疵(ci)，使(shi)其真正可以符合實際的(de)(de)標準。

由于棉(mian)(mian)(mian)纖維(wei)(wei)大容量(liang)測(ce)試儀(yi)僅涉及棉(mian)(mian)(mian)花(hua)(hua)的(de)(de)(de)長度(du)(du)、線密(mi)度(du)(du)、成熟(shu)度(du)(du)比(bi)、強力、整齊度(du)(du)等，而棉(mian)(mian)(mian)花(hua)(hua)的(de)(de)(de)短絨率、成熟(shu)度(du)(du)百分比(bi)、未成熟(shu)纖維(wei)(wei)百分比(bi)、棉(mian)(mian)(mian)結、雜(za)質等疵(ci)(ci)點的(de)(de)(de)測(ce)試都(dou)與紡紗(sha)的(de)(de)(de)要求出(chu)入偏(pian)離較(jiao)大。 其與紡紗(sha)的(de)(de)(de)實際(ji)質量(liang)指(zhi)(zhi)標(biao)(biao)的(de)(de)(de)控(kong)(kong)(kong)制(zhi)關聯(lian)性較(jiao)小，與紡紗(sha)半制(zhi)品控(kong)(kong)(kong)制(zhi)的(de)(de)(de)梳(shu)(shu)(shu)棉(mian)(mian)(mian)條、精梳(shu)(shu)(shu)條的(de)(de)(de)質量(liang)指(zhi)(zhi)標(biao)(biao)無法建立對應(ying)關系(xi)，使(shi)得棉(mian)(mian)(mian)花(hua)(hua)測(ce)試指(zhi)(zhi)標(biao)(biao)與棉(mian)(mian)(mian)條質量(liang)控(kong)(kong)(kong)制(zhi)指(zhi)(zhi)標(biao)(biao)難以形成對應(ying)控(kong)(kong)(kong)制(zhi)關系(xi)，所以建立棉(mian)(mian)(mian)花(hua)(hua)混配棉(mian)(mian)(mian)單纖維(wei)(wei)測(ce)試儀(yi)質量(liang)控(kong)(kong)(kong)制(zhi)指(zhi)(zhi)標(biao)(biao)，有利于清(qing)梳(shu)(shu)(shu)聯(lian)工序危害性疵(ci)(ci)點的(de)(de)(de)清(qing)除和控(kong)(kong)(kong)制(zhi)，而且這些控(kong)(kong)(kong)制(zhi)指(zhi)(zhi)標(biao)(biao)都(dou)會對后(hou)工序梳(shu)(shu)(shu)棉(mian)(mian)(mian)條、精梳(shu)(shu)(shu)條的(de)(de)(de)控(kong)(kong)(kong)制(zhi)指(zhi)(zhi)標(biao)(biao)產(chan)生(sheng)影響。
