6、明a.多股少股:捻線中多余乙綸單絲根數(shù)或缺少乙綸單絲根數(shù)。b.麻皮線:線股粗細(xì)不均勻,捻制張力不一或捻度不一等原因,造成線股扭曲處最高點(diǎn)不在一直線上。c.松緊線:捻線由于局部加捻過(guò)緊,捻線內(nèi)外捻比例不當(dāng),線股之間相互松弛。d.油污線:線絞上沾有油、污、色、銹等斑漬,統(tǒng)稱油污線。e.起毛線:捻線表面由于摩擦或其他原因使線起毛。f.小辮子線:捻線局部扭曲,呈小辮子狀。g.絞形扭曲:整絞網(wǎng)絡(luò)扭曲不平直。www.bzfxw.comh.附外觀疵點(diǎn)項(xiàng)目標(biāo)樣。2等級(jí)評(píng)定2.1按技術(shù)指標(biāo)及外觀指標(biāo)考核,分一等品、二等品,以其中最低一項(xiàng)指標(biāo)評(píng)定該絞網(wǎng)線的等級(jí)。2.2產(chǎn)品的等級(jí)按樣品的等級(jí)評(píng)定。2.3技術(shù)指標(biāo)綜
