1. Kusiyana kwa mtengo. Pakadali pano, mitengo yonse ya PU wamba pamsika ndi 15-30 (mamita), pomwe mitengo yonse ya chikopa cha microfiber ndi 50-150 (mamita), kotero mtengo wa chikopa cha microfiber ndi kangapo kuposa PU wamba.
2. Kagwiridwe ka ntchito ka pamwamba pa chikopa cha microfiber ndi PU wamba ndi ma polyurethane resins, mtundu ndi kalembedwe ka PU wamba komwe kwakhala kotchuka kwa zaka zambiri kudzakhala kwakukulu kuposa ka chikopa cha microfiber. Koma nthawi zambiri, polyurethane resin pamwamba pa chikopa cha microfiber imakhala ndi kukana kwamphamvu kwa kuwonongeka, kukana asidi ndi alkali, komanso kukana hydrolysis kuposa PU wamba, ndipo kulimba kwa mtundu ndi kapangidwe kake kudzakhalanso kolimba.
3. Nsalu yoyambira ndi yosiyana. PU yachizolowezi imapangidwa ndi nsalu yolukidwa, nsalu yolukidwa kapena nsalu yosalukidwa, kenako n’kupakidwa ndi utomoni wa polyurethane. Chikopa cha microfiber chimapangidwa ndi nsalu yosalukidwa ndi chikopa cha microfiber yokhala ndi kapangidwe ka magawo atatu ngati nsalu yoyambira, yokutidwa ndi utomoni wa polyurethane wochita bwino kwambiri. Zipangizo zosiyanasiyana, njira ndi miyezo yaukadaulo ya nsalu yoyambira zimakhudza kwambiri momwe chikopa cha microfiber chimagwirira ntchito.
4. Kagwiridwe ka ntchito ndi kosiyana. Chikopa cha microfiber ndi chabwino kuposa PU wamba pankhani ya mphamvu, kukana kukalamba, kuyamwa chinyezi, chitonthozo ndi zizindikiro zina zogwirira ntchito. M'mawu a anthu wamba, chimafanana ndi chikopa chenicheni, cholimba komanso chimamveka bwino.
5. Kuyembekezeka kwa msika. Mu msika wamba wa PU, chifukwa cha malire ochepa aukadaulo, kuchuluka kwakukulu kwa zinthu, komanso mpikisano waukulu, malondawa amachepa ndikudula zinthu, zomwe sizikugwirizana ndi lingaliro la ogula lomwe likukwera, ndipo makasitomala amsika akudera nkhawa. Chifukwa cha malire apamwamba aukadaulo komanso mphamvu zochepa zopangira, chikopa cha microfiber chikudziwika kwambiri ndi ogula, ndipo msika uli ndi malo ambiri oti ukule.
6. Chikopa cha microfiber ndi PU wamba zimayimira zinthu zosiyanasiyana zomwe zimapangidwa pamlingo wosiyanasiyana wa chikopa chopangidwa, motero zimakhala ndi zotsatira zina zosinthira. Ndikukhulupirira kuti ndi chilolezo cha anthu ambiri, chikopa cha microfiber chidzagwiritsidwa ntchito kwambiri m'mbali zonse za moyo wa anthu.
Chikopa cha PU chimatanthauza chikopa cha PU wamba, polyurethane pamwamba pake komanso nsalu yosalukidwa kapena nsalu yolukidwa, magwiridwe antchito ake ndi ambiri, mtengo wake ndi wokulirapo pakati pa 10-30 pa mita imodzi.
Chikopa cha microfiber ndi chikopa chopangidwa ndi microfiber PU. Chophimba cha polyurethane chapamwamba kwambiri chimalumikizidwa ku nsalu yoyambira ya microfiber. Chimagwira ntchito bwino kwambiri, makamaka kukana kuwonongeka ndi kukanda. Mtengo wake nthawi zambiri umakhala pakati pa 50-150 pa mita imodzi.
Chikopa chenicheni, chomwe ndi chikopa chachilengedwe, chimapangidwa kuchokera ku khungu lochotsedwa ku nyama. Chimapuma bwino komanso chimakhala chomasuka. Mtengo wa chikopa chenicheni (chikopa chapamwamba) ndi wokwera mtengo kuposa wa chikopa cha microfiber.
