尼(ni)(ni)龍(long)(long)拉(la)鏈(lian)是拉(la)鏈(lian)的(de)一種，是用(yong)尼(ni)(ni)龍(long)(long)單絲通(tong)過加(jia)熱(re)壓模(mo)纏繞中(zhong)心(xin)線組成的(de)。根據拉(la)鏈(lian)的(de)材(cai)質，拉(la)鏈(lian)分為(wei)三大類：金(jin)屬拉(la)鏈(lian)、樹脂(zhi)拉(la)鏈(lian)、尼(ni)(ni)龍(long)(long)拉(la)鏈(lian)。金(jin)屬拉(la)鏈(lian)牙(ya)齒(chi)是用(yong)銅(tong)線或鋁(lv)線通(tong)過排牙(ya)機器(qi)排出來(lai)的(de)，樹脂(zhi)拉(la)鏈(lian)牙(ya)齒(chi)是用(yong)聚脂(zhi)塑料米通(tong)過染料配色并通(tong)過注塑機器(qi)排出來(lai)的(de)，而尼(ni)(ni)龍(long)(long)拉(la)鏈(lian)牙(ya)齒(chi)是用(yong)尼(ni)(ni)龍(long)(long)單絲通(tong)過加(jia)熱(re)壓模(mo)纏繞中(zhong)心(xin)線組成的(de)。相比(bi)金(jin)屬拉(la)鏈(lian)、樹脂(zhi)拉(la)鏈(lian)，尼(ni)(ni)龍(long)(long)拉(la)鏈(lian)有成本低、產量大、普(pu)及(ji)率(lv)高的(de)特點。
