Kutuluka kwa zinthuzi kwadzetsa chipwirikiti pamakampani opanga nsalu. Zimamveka kuti mtundu uwu wa nayiloni 66 ulusi uli ndi makhalidwe osiyanasiyana monga kulimba kwakukulu, kulimba kwambiri, ndi kukana kwa UV, ndipo ndi chimodzi mwa zipangizo zodziwika kwambiri pamakampani opanga nsalu.
M'dziko la nsalu, Total Bright Polyester Filament Yarn ikupitilizabe kulamulira ngati imodzi mwazinthu zosunthika komanso zotsika mtengo zopangira ulusi.
Makampani opanga nsalu amasintha nthawi zonse ku zovuta zatsopano ndi zosowa za msika. Imodzi mwa madera omwe makampani akhala akukumana ndi mavuto ndi m'dera la chitetezo cha moto. Zovala zosagwira moto zimafunidwa m'mafakitale omwe zoopsa zamoto ndizofala, monga minda yamagetsi ndi mafuta.
Ulusi wa poliyesitala ndi chinthu chosunthika chomwe chimagwiritsidwa ntchito mosiyanasiyana, kuchokera ku zovala kupita ku zida zapanyumba komanso ngakhale mafakitale. Ulusi wopangirawu umadziwika chifukwa cha kulimba kwake, mphamvu zake, komanso kukana kutsika, kuzimiririka, ndi mankhwala. Tiyeni tiwone madera ena omwe ulusi wa mafakitale a polyester umagwiritsidwa ntchito kwambiri.
Ulusi wa polyester filament, chinthu chomwe chimapezeka ponseponse pamakampani opanga nsalu, ndi mtundu wa ulusi wopangidwa ndi zingwe zazitali, zosalekeza za polyester. Ulusi umenewu umapangidwa potulutsa poliyesitala wosungunula kudzera m'mabowo ting'onoting'ono, zomwe zimapangitsa kuti zikhale zosalala, zolimba, komanso zamitundumitundu.
Optical White Polyester Trilobal Shaped Filament yadziwika kuti ndi imodzi mwazinthu zosunthika komanso zapamwamba kwambiri pazovala. Nkhaniyi ndi mtundu wa polyester filament yomwe imapangidwa kukhala mawonekedwe a trilobal, yomwe imapangitsa kuti ikhale yapadera yonyezimira.
