縫紉線規(guī)格?
縫紉線的規(guī)格,型號(hào)分長(zhǎng)纖維類和短纖維類,叫法和區(qū)分方法也不一樣。
長(zhǎng)纖維類縫紉線,市場(chǎng)也稱邦迪線,尼龍線,錦綸線,珠光線,高強(qiáng)線,特多龍線,絲光線等;規(guī)格用D數(shù)和股數(shù)區(qū)分,且D數(shù)越大線徑越粗,常用的型號(hào)線徑由細(xì)到粗分別如下: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和股數(shù)表示,相反,支數(shù)越小,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
