Ndi chitukuko cha nsomba, zinthu zopha nsomba ndi kusaka si nsomba zokha, koma zida za nsomba zikupita patsogolo ndi nthawi.Maukonde ophera nsomba amagawidwa m'maukonde a gill, maukonde okoka (maukonde), maukonde a purse seine, kumanga maukonde ndi kuyala maukonde.

Maukonde omwe amagwiritsidwa ntchito kwambiri amagawidwa motere:kukoka maukonde, maukonde oyendetsa,zomatira makoka.Ndikofunikira kukhala ndi kuwonekera kwakukulu (gawo la mauna a nayiloni) ndi mphamvu, kukana kwabwino, kukana ma abrasion, kukhazikika kwa mauna ndi kufewa, komanso kutalika koyenera pakupuma (22% mpaka 25%).Iwo kukonzedwa ndi monofilament, multifilament wokhota ulusi (ndi knotted ukonde) kapena monofilament warp kuluka (raschel, amene ali ukonde wopanda mfundo), mankhwala kutentha umodzi (nodule atakhazikika), utoto ndi yachiwiri kutentha mankhwala (osakhazikika maukonde kukula).Zopangira zoluka maukonde ophera nsomba ndi zingwe 15-36 za nayiloni ya 210-denier, polyester multifilament ndi ethylene monofilament yokhala ndi mainchesi 0.8-1.2 mm.Njira zoluka zikuphatikizapo knotting, kupindika ndi kuluka koluka.
Kodi maukonde amagwiritsidwa ntchito bwanji?
1. Ukonde ndi zida zopangira asodzi, zomwe zimatha kugwira nsomba, nkhanu ndi nkhanu pansi pamadzi.
2. Ukonde wophera nsomba ungagwiritsidwenso ntchito ngati chida chotetezera, monga maukonde oteteza nsomba za shark, zomwe zingagwiritsidwe ntchito kuteteza nsomba zazikulu zoopsa monga shaki.
3. Maukonde opha nsomba amatha kupanga chithunzithunzi chojambula.
