Zosefera zomwe zimapangidwa ndi opanga zitsulo zosapanga dzimbiri zimakhala ndi ntchito zingapo, ndipo zinthu zambiri zimagwiritsidwa ntchito ngati zosefera. Chosefera chomwe chimapangidwa ndi opanga zinthu zakale zachitsulo chosapanga dzimbiri chimapangidwa ndi ma waya; nthawi zina pakati pa chinsalucho chimakhala ndi mauna wandiweyani kuti awonjezere mphamvu. Poyamba, chinthu chosefera chopangidwa ndi opanga zitsulo zosapanga dzimbiri chimangogwiritsidwa ntchito kusefera gasi. Chifukwa chomwe sichimaganiziridwa pakusefera kwamadzi ndikuti kukula kwa zinthu zosefera sikukhazikika ndipo kumatalikirana ndi kusefera kwakukulu. Komabe, m'zaka zaposachedwa, ukadaulo wa dense mesh reinforced element wapita patsogolo kwambiri. Mwachitsanzo, pofuna kupititsa patsogolo kukhazikika kwazinthu zosefera, njira zotsatirazi zimagwiritsidwa ntchito:
Pamwamba pa fyuluta, micro denier fiber imayikidwa pamwamba pa fyuluta; pamwamba pa kumverera kumachitidwa ndi mapeto osalala; ndipo (3) nsalu yabwinoko komanso yamphamvu yolimbirana mauna imagwiritsidwa ntchito.
Mukatengera matekinoloje atsopanowa, kuchuluka kwa zinthu zosefera kudzakulitsidwa. Itha kugwiritsidwa ntchito osati pazosefera zochotsa fumbi zogwira ntchito kwambiri, komanso muzosefera zamadzi a vacuum (monga mtundu wa ng'oma, mtundu wa ng'oma ndi chosefera chopingasa lamba). Kuphatikiza apo, chinthu chosefera chopangidwa ndi wopanga zosefera zazing'ono zosapanga dzimbiri zakhala zikugwiritsidwa ntchito muzosefera zachidebe kuti zisefe chakudya ndi mankhwala.
