紗(sha)線性能對織物質量的影響

一、紗(sha)線(xian)(xian)(xian)(xian)(xian)的(de)(de)(de)(de)(de)外(wai)觀(guan)形(xing)(xing)態(tai)特征對(dui)織物(wu)的(de)(de)(de)(de)(de)影(ying)響紗(sha)線(xian)(xian)(xian)(xian)(xian)的(de)(de)(de)(de)(de)外(wai)觀(guan)性能主要指紗(sha)線(xian)(xian)(xian)(xian)(xian)的(de)(de)(de)(de)(de)細(xi)(xi)度(du)，即紗(sha)線(xian)(xian)(xian)(xian)(xian)的(de)(de)(de)(de)(de)相(xiang)對(dui)粗細(xi)(xi)。紗(sha)線(xian)(xian)(xian)(xian)(xian)的(de)(de)(de)(de)(de)粗細(xi)(xi)直(zhi)接決定(ding)著織物(wu)的(de)(de)(de)(de)(de)規(gui)格、品(pin)種、風(feng)格、用途和物(wu)理機械性能。紗(sha)線(xian)(xian)(xian)(xian)(xian)的(de)(de)(de)(de)(de)粗細(xi)(xi)一般(ban)可用相(xiang)對(dui)粗細(xi)(xi)或幾(ji)何粗細(xi)(xi)的(de)(de)(de)(de)(de)指標來表示(shi)。由于紗(sha)線(xian)(xian)(xian)(xian)(xian)截面(mian)形(xing)(xing)狀的(de)(de)(de)(de)(de)不(bu)規(gui)則和容易(yi)變形(xing)(xing)；短纖紗(sha)的(de)(de)(de)(de)(de)毛(mao)羽較多(duo)，變形(xing)(xing)紗(sha)的(de)(de)(de)(de)(de)膨松化使紗(sha)線(xian)(xian)(xian)(xian)(xian)的(de)(de)(de)(de)(de)邊界不(bu)清；再加上(shang)幾(ji)何形(xing)(xing)態(tai)的(de)(de)(de)(de)(de)測試的(de)(de)(de)(de)(de)繁瑣(suo)不(bu)變，故紗(sha)線(xian)(xian)(xian)(xian)(xian)的(de)(de)(de)(de)(de)通常采用相(xiang)對(dui)粗細(xi)(xi)的(de)(de)(de)(de)(de)細(xi)(xi)度(du)指標來描述，簡稱(cheng)“細(xi)(xi)度(du)”。紗(sha)線(xian)(xian)(xian)(xian)(xian)的(de)(de)(de)(de)(de)細(xi)(xi)度(du)有多(duo)種表示(shi)方(fang)法，例如號數(shu)、公制支數(shu)、英(ying)制支數(shu)、旦(dan)尼爾(er)等。紗(sha)線(xian)(xian)(xian)(xian)(xian)的(de)(de)(de)(de)(de)捻(nian)(nian)度(du)用每米(mi)或每英(ying)寸的(de)(de)(de)(de)(de)捻(nian)(nian)回數(shu)表示(shi)。捻(nian)(nian)回的(de)(de)(de)(de)(de)方(fang)向分S捻(nian)(nian)和Z捻(nian)(nian)。在一定(ding)捻(nian)(nian)度(du)范圍內，紗(sha)的(de)(de)(de)(de)(de)強度(du)隨(sui)捻(nian)(nian)度(du)增加而增大。單紗(sha)的(de)(de)(de)(de)(de)捻(nian)(nian)向和股線(xian)(xian)(xian)(xian)(xian)的(de)(de)(de)(de)(de)捻(nian)(nian)向搭配根據(ju)股線(xian)(xian)(xian)(xian)(xian)的(de)(de)(de)(de)(de)用途選擇...
