Microfiber ndi chidule cha microfiber PU kupanga chikopa, amene sanali nsalu nsalu ndi maukonde azithunzi-azithunzi atatu kapangidwe ulusi wopangidwa ndi microfiber choyambira CHIKWANGWANI ndi carding ndi needling, ndiyeno kukonzedwa ndi njira yonyowa, PU utomoni kumizidwa, kuchepetsa alkali, utoto utoto ndi kumaliza ndi njira zina pomaliza kupanga microfiber chikopa.

PU Microfiber, dzina lonse la chikopa cha microfiber cholimbitsa PU, ndi mtundu wa chikopa chopanga chopangidwa ndi utomoni wapamwamba kwambiri wa polyurethane (PU) ndi nsalu ya microfiber. Lili ndi dongosolo pafupi ndi chikopa, la m'badwo wachitatu wa chikopa chochita kupanga, chokhala ndi zinthu zabwino kwambiri, monga kukana kuvala, kuzizira, kutsekemera kwa mpweya ndi kukalamba. Popanga chikopa cha microfiber, zida zamankhwala monga zikopa za chikopa cha ng'ombe ndi ma microfiber a polyamide nthawi zambiri amawonjezeredwa. Zinthuzi ndizodziwika pamsika chifukwa cha mawonekedwe ake ngati dermal, ndipo zimakhala ndi mawonekedwe ofewa, kuteteza chilengedwe komanso mawonekedwe okongola.

Polyurethane (PU) ndi mtundu wa polima pawiri, amene amapangidwa ndi zimene gulu isocyanate ndi hydroxyl gulu. Amagwiritsidwa ntchito kwambiri m'mafakitale a zovala, zinthu zotchinjiriza, zopangira mphira ndi zokongoletsera zapanyumba chifukwa cha kukana kupindika, kufewa, katundu wamphamvu wamanjenje komanso kuthekera kwa mpweya. PU microfiber nthawi zambiri imagwiritsidwa ntchito popanga zovala chifukwa chapamwamba kuposa PVC, ndipo zovala zopangidwa zimakhala ndi chikopa choyerekeza.
Njira yopangira khungu la microfiber imaphatikizapo kupanga nsalu yopanda nsalu yokhala ndi maukonde amitundu itatu pophatikiza ndi misomali ndi njira zina, kenako ndikuipanga ndi kunyowa, kumiza kwa utomoni wa PU, utoto wapakhungu ndi kumaliza. Nkhaniyi ndi ntchito yabwino, yoyenera pazochitika zosiyanasiyana zogwiritsira ntchito.
