縫紉線規格?
縫紉線的規格,型号分長纖維類和(hé)短(duǎn)纖維類,叫法和(hé)區(qū)分方法也不一樣。
長纖維類縫紉線,市場(chǎng)也稱邦迪線,尼龍線,錦綸線,珠光線,高(gāo)強線,特多(duō)龍線,絲光線等;規格用D數(shù)和(hé)股數(shù)區(qū)分,且D數(shù)越大(dà)線徑越粗,常用的型号線徑由細到粗分别如下:100D/3,120D/3,150D/3,210D/2,210D/3,250D/2,250D/3,300D/3,420D/3,630D/3,840D/3,1050D/3等。
短(duǎn)纖維類縫紉線,市場(chǎng)也稱SP線,棉線,滌綸線,PP線。用支數(shù)S和(hé)股數(shù)表示,相反,支數(shù)越小(xiǎo),線徑越粗;如:60s/2,60s/3,50s/2,50s/3,40s/2,40s/3,30s/2,30s/3,20s/2,20s/3,20s/4,20s/9,12s/3等
