Zopangira PU Chikopa
PU ndi chidule cha poly urethane mu Chingerezi. PU chikopa ndi mtundu wa zinthu zopangapanga zotsanzira zikopa. Dzina lake la mankhwala ndi "polyurethane". Chikopa cha PU ndi pamwamba pa polyurethane, yomwe imadziwikanso kuti "PU artificial leather".
Chikopa cha PU chimakhala ndi mawonekedwe abwino, sichimapindika, chimakhala chofewa kwambiri, chimakhala cholimba kwambiri, chimakhala ndi mpweya wabwino. The mpweya permeability angafikire 8000-14000g/24h/cm², ali mkulu peel mphamvu ndi mkulu kukana madzi kuthamanga. Ndizinthu zoyenera pamwamba ndi pansi pa nsalu zopanda madzi komanso zopuma mpweya.
Chikopa cha Microfiber
Chikopa cha Microfiber, chomwe chimatchedwanso kuti "chikopa chochita kupanga chokhala ndi zikopa za ng'ombe", si chikopa cha ng'ombe, koma zikopa za ng'ombe zimathyoledwa ndikuwonjezeredwa ndi zinthu za polyethylene kuti zikhalenso laminated, ndiyeno pamwamba pake ndi sprayed ndi zipangizo za mankhwala kapena yokutidwa ndi PVC kapena filimu ya cowhide.
Maonekedwe a chikopa cha microfiber ndi ofanana kwambiri ndi chikopa chenicheni. Zogulitsa zake ndi zapamwamba kuposa zikopa zachilengedwe malinga ndi makulidwe ofanana, mphamvu yakung'ambika, kuwala kwamtundu komanso kugwiritsa ntchito zikopa, ndipo zakhala njira yopangira zikopa zamakono.
Chikopa cha mapuloteni
Zopangira za chikopa cha mapuloteni ndi silika ndi chigoba cha mazira. Silikayo amapangidwa ndi micronized ndi kukonzedwa ndi njira zopanda mankhwala pogwiritsa ntchito kuyamwa kwachinyontho komanso kutulutsa mphamvu zaufa wa silika wa protein komanso kukhudza kwake kofewa.
Chikopa cha puloteni ndi mtundu wansalu zaukadaulo ndipo ndi chinthu chatsopano chosintha chilengedwe chopangidwa ndi zida za polima zopanda zosungunulira. Imabwezeretsa kwambiri mawonekedwe a makwinya a chikopa chenicheni, imakhala ndi kukhudza kofanana ndi mwana, ndipo imakhala ndi mawonekedwe ofewa okhala ndi drape inayake ndi kutambasula. Nsaluyi ndi yofewa, yowongoka pakhungu, yopuma, yosasunthika, yosavala, yokhazikika, yosavuta kuyeretsa, yotetezeka komanso yosamalira chilengedwe.
Suede
Suede ndi chikopa cha nyama zakuthengo, chomwe chimawononga mbewu zambiri, chokulirapo kuposa chikopa cha nkhosa, komanso minofu yolimba kwambiri. Ndi chikopa chapamwamba kwambiri chopangira suede. Popeza kuti suede ndi nyama yotetezedwa yamtundu wachiwiri ndipo chiwerengero chake ndi chosowa, opanga nthawi zonse amagwiritsa ntchito zikopa, zikopa za mbuzi, zikopa za nkhosa, ndi zikopa zina zanyama kupanga zinthu za suede kudzera munjira zingapo.
Chifukwa cha kusowa kwa suede zachilengedwe, kuti azivala zokongola komanso zapamwamba, anthu apanga nsalu zotsanzira za suede zachilengedwe, zomwe timatcha kuti suede.
Suede Nap

Zina mwakuthupi ndi magwiridwe antchito a suede yokumba zimaposa za suede yeniyeni. Lili ndi mtundu wothamanga kwambiri, kukana madzi ndi asidi ndi alkali kukana zomwe zikopa zenizeni sizingafanane; Ili ndi kuchapa kwambiri komanso kuthamanga kwamtundu wamtundu, velvet wochuluka komanso wosakhwima komanso kulemba bwino, kumva kofewa komanso kosalala, kuthamangitsa madzi komanso kupuma, mtundu wowala komanso mawonekedwe ofanana.
Chikopa cha Veloue
Zovala zomwe timaziwona nthawi zambiri zimatanthawuza luso lapadera lachikopa, lomwe liri pafupi kwambiri ndi suede weniweni. Zopangira zake zingakhale zikopa za ng'ombe, zikopa za nkhosa kapena nkhumba, ndi zina zotero. Pambuyo pokonza, zimatha kupereka mawonekedwe abwino kwambiri. Kaya ikhoza kukhala suede yabwino zimatengera momwe akupera.
Mbali yamkati (mbali ya thupi) ya chikopa imapukutidwa, ndipo tinthu tating'onoting'ono timakhala tokulirapo. Pambuyo pakuwotcha ndi njira zina, imakhala ngati kukhudza kwa velvet. Gawo loyamba la suede, suede, ndi lachiwiri la suede pamsika ndi mtundu uwu wa kugaya. Izi zikufotokozeranso chifukwa chake suede amatchedwa Suede mu Chingerezi.

Ma pores a chikopa cha mbuzi amakonzedwa m'mizere yofanana ndi "tale-ngati" mawonekedwe, pamwamba pake ndi osakhwima, ulusi ndi wolimba, ndipo pali ma pores ambiri abwino omwe amakonzedwa mu semicircle, ndipo kumverera kumakhala kolimba. Chikopa cha mbuzi chimakhala ndi timabowo tating'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono. Pali chiwerengero chachikulu cha pores chabwino chokonzedwa mu semicircle, ndipo kumverera kumakhala kolimba. Chikopa cha mbuzi tsopano chikhoza kupangidwa kukhala mitundu yosiyanasiyana ya zikopa. Chikopa chomwe chimachapidwa sichimakutidwa ndipo chimatha kutsukidwa m'madzi. Sizizimiririka ndipo imakhala ndi kachulukidwe kakang'ono kwambiri.
