漁網線廠家所用的(de)(de)(de)主(zhu)要(yao)材(cai)料(liao)是盾牌(pai)直徑小于4毫米的(de)(de)(de)紡織網和絲線，鋼絲的(de)(de)(de)物理機械性能(neng)(neng)有:一(yi)定的(de)(de)(de)粗糙度、足夠的(de)(de)(de)強度、適(shi)當的(de)(de)(de)伸(shen)長率、良(liang)好(hao)的(de)(de)(de)柔韌性、彈性、結構(gou)穩定性、耐腐蝕和抗老化性能(neng)(neng)、均勻的(de)(de)(de)厚度、平滑的(de)(de)(de)耐磨性。

    漁(yu)網線(xian)(xian)廠家的種類根(gen)據制(zhi)作(zuo)材料可以分(fen)為兩(liang)類：植物纖維(wei)網和合成纖維(wei)網。前者(zhe)耐(nai)腐蝕性差(cha)，在漁(yu)業中已被(bei)淘汰。后者(zhe)在當今漁(yu)業中應用(yong)廣泛，主(zhu)要包括(kuo)尼龍(long)線(xian)(xian)（PA）、聚(ju)(ju)酯線(xian)(xian)（PES）、乙(yi)(yi)烯線(xian)(xian)（PE）、聚(ju)(ju)丙烯線(xian)(xian)（PP）、維(wei)尼綸線(xian)(xian)（PVA）、聚(ju)(ju)氯乙(yi)(yi)烯線(xian)(xian)（PVC）、聚(ju)(ju)偏氯乙(yi)(yi)烯線(xian)(xian)（PVD）。

 ;   按漁(yu)網線(xian)廠家進行結構設計可分為單絲、捻絲和(he)編(bian)線(xian)三大(da)類(lei)：

    一.單(dan)(dan)(dan)絲(si)：直徑為(wei)0.1-1.5mm的單(dan)(dan)(dan)絲(si)，如尼龍(long)單(dan)(dan)(dan)絲(si)，適用于漁具和編(bian)織刺網(wang)。1.單(dan)(dan)(dan)捻(nian)線：纖維(wei)；單(dan)(dan)(dan)絲(si)；單(dan)(dan)(dan)紗(sha)。2.雙捻(nian)：纖維(wei)；單(dan)(dan)(dan)（Z或(huo)S捻(nian)）；單(dan)(dan)(dan)（S或(huo)Z捻(nian)）。3.8股(gu)(gu)(gu)編(bian)織紗(sha)（每股(gu)(gu)(gu)平行）:1，芯紗(sha)（2根單(dan)(dan)(dan)紗(sha)）;2，股(gu)(gu)(gu)紗(sha)（3根單(dan)(dan)(dan)紗(sha)）。4.8股(gu)(gu)(gu)編(bian)織（一股(gu)(gu)(gu)磨(mo)損，一股(gu)(gu)(gu)壓制，XX是由4個(ge)結(jie)節(jie)(jie)形成的節(jie)(jie)距(ju)長度）。5.16股(gu)(gu)(gu)編(bian)線（穿2股(gu)(gu)(gu)壓2股(gu)(gu)(gu)，XX為(wei)8個(ge)花節(jie)(jie)形成的螺(luo)距(ju)控(kong)制長度）

    二.扭曲：捻(nian)(nian)(nian)2、3或(huo)4股(gu)(gu)(gu)(gu)的(de)(de)(de)紗(sha)(sha)線(xian)(xian)。有(you)單(dan)捻(nian)(nian)(nian)、雙捻(nian)(nian)(nian)和復合(he)捻(nian)(nian)(nian)等類(lei)型(xing)。構成(cheng)網線(xian)(xian)的(de)(de)(de)半成(cheng)品結(jie)構稱為(wei)(wei)股(gu)(gu)(gu)(gu)，簡稱股(gu)(gu)(gu)(gu)。如單(dan)紗(sha)(sha)單(dan)捻(nian)(nian)(nian)、單(dan)捻(nian)(nian)(nian)雙捻(nian)(nian)(nian)、復捻(nian)(nian)(nian)雙捻(nian)(nian)(nian)。單(dan)股(gu)(gu)(gu)(gu)絞線(xian)(xian)也叫單(dan)股(gu)(gu)(gu)(gu)絞線(xian)(xian)。一(yi)種(zhong)由數(shu)(shu)根(gen)單(dan)紗(sha)(sha)或(huo)單(dan)絲在一(yi)次通(tong)過(guo)中(zhong)加(jia)(jia)捻(nian)(nian)(nian)而(er)成(cheng)的(de)(de)(de)產(chan)(chan)品。由于容易解(jie)捻(nian)(nian)(nian)，很少(shao)用(yong)于漁業。多股(gu)(gu)(gu)(gu)加(jia)(jia)捻(nian)(nian)(nian)紗(sha)(sha)，也稱為(wei)(wei)多股(gu)(gu)(gu)(gu)紗(sha)(sha)，是(shi)(shi)由多根(gen)單(dan)紗(sha)(sha)或(huo)長絲加(jia)(jia)捻(nian)(nian)(nian)成(cheng)股(gu)(gu)(gu)(gu)線(xian)(xian)，然后沿相反(fan)方向(xiang)加(jia)(jia)捻(nian)(nian)(nian)成(cheng)股(gu)(gu)(gu)(gu)線(xian)(xian)（通(tong)常為(wei)(wei)3股(gu)(gu)(gu)(gu)）的(de)(de)(de)組合(he)。這種(zhong)結(jie)構主要用(yong)于合(he)成(cheng)纖(xian)維網，是(shi)(shi)各種(zhong)漁具的(de)(de)(de)主要生產(chan)(chan)線(xian)(xian)。復合(he)加(jia)(jia)捻(nian)(nian)(nian)紗(sha)(sha)是(shi)(shi)通(tong)過(guo)在相反(fan)方向(xiang)上加(jia)(jia)捻(nian)(nian)(nian)數(shu)(shu)根(gen)（3或(huo)4根(gen)）復合(he)加(jia)(jia)捻(nian)(nian)(nian)紗(sha)(sha)而(er)制成(cheng)的(de)(de)(de)產(chan)(chan)品。該螺紋更粗、更硬，用(yong)作(zuo)大型(xing)拖網的(de)(de)(de)網線(xian)(xian)。

    三.電(dian)線。由(you)幾股(gu)偶數股(gu)（如6、8、12、16股(gu)）組成的線，成對或單股(gu)或雙股(gu)的線相互交織(zhi)(zhi)(zhi)或編(bian)織(zhi)(zhi)(zhi)。漁(yu)網(wang)線廠(chang)家編(bian)織(zhi)(zhi)(zhi)中心有(you)芯(xin)的金(jin)屬絲與(yu)芯(xin)編(bian)織(zhi)(zhi)(zhi)，無芯(xin)的金(jin)屬絲與(yu)芯(xin)編(bian)織(zhi)(zhi)(zhi)。漁(yu)網(wang)線廠(chang)家編(bian)織(zhi)(zhi)(zhi)通用無線芯(xin)。
