Dzina lonse lachikopa cha microfiberndi “chikopa cha PU cholimbikitsidwa ndi microfiber", yomwe imakutidwa ndi PU kupaka pogwiritsa ntchito nsalu yoyambira ya microfiber. Ili ndi kukana kuvala bwino kwambiri, kukana kuzizira kwambiri, kulola mpweya kulowa, komanso kukana kukalamba. Kuyambira mu 2000, mabizinesi ambiri am'nyumba nawonso ayika ndalama mu kafukufuku ndi chitukuko ndi kupanga ma microfiber. Komabe, kafukufuku wozama wa wopanga adapeza kuti chikopa cha microfiber chomwe chinalipo chinali ndi polyurethane pamwamba pa substrate yokha, ngakhale kukana kuvala kwa chikopacho kunakula kwambiri, koma magwiridwe antchito onse a chikopacho adakhudzidwa chifukwa cha kuthekera kochepa kolumikizana pakati pa polyurethane kupaka ndi substrate.
Komabe, kuonekera kwaulusi wa microfibers wochokera ku bioZimathetsa vutoli bwino. Mu njira yokonzekera microfiber yochokera ku bio, gawo lolimbitsa ndi gawo la maziko achilengedwe zimakhazikika ndikusokedwa zonse. Mu gawo lopaka polyurethane, ukadaulo wa ultrasonic ndi ultrasound, mbali zimalumikiza kulowa kwa polyurethane ku dzenje lofewa ndi dzenje, zimalimbitsa kulumikizana pakati pa pamwamba ndi pansi pa polyurethane, motero zimapangitsa polyurethane kukwera ndi kutsika kudzera mu dzenje lolumikizira kupanga chinthu chachilengedwe, kuthetsa bwino ukadaulo womwe ulipo wa polyurethane glue layer ndi nsalu yoyambira yomwe siili yolimba mokwanira, Kenako imatha kuthetsa vuto lochotsa khungu la polyurethane layer. Kumbali imodzi, imatha kulimbitsa mphamvu yonse ya nsalu yoyambira ndikuwonetsetsa kuti chikopa chonse chili cholimba. Kumbali ina, gawo la maziko achilengedwe limagwiritsa ntchito ulusi wa chitosan, womwe ungathe kusewera gawo lake loletsa zinthu zowononga, ndipo umakhala wothandiza pakukonzekera zinthu zoteteza antchito kwa ogwira ntchito mumakampani a nyukiliya. Ulusi wa elastic wachilengedwe umagwiritsidwa ntchito kukonza kulimba konse kwa nsalu yoyambira, komanso kuphatikiza kwa ulusi wa Arlene kuti zitsimikizire kulimba konse ndi mphamvu ya nsalu yoyambira, kukonza magwiridwe antchito onse a chikopa.
Chiyembekezo cha chitukuko cha ulusi wa microfibers wopangidwa ndi zamoyo
Choyamba, microfiber yochokera ku bio ili ndi kukana bwino kwa hydrolysis, kukana thukuta, kukana ukalamba, kukana kuvala komanso kukana madzi mwamphamvu, kukana kuipitsa, chikopa ndi chosavuta kusamalira komanso chitetezo cha chilengedwe chosakhala cha poizoni.
Chachiwiri, microfiber yochokera ku bio kudzera mu kuphatikiza kwa biology pamlingo wa mizu ndi kulimbitsa, kulimbitsa mphamvu yonse ndi kusinthasintha kwa nsalu yoyambira ndi zina zotero, kutsimikizira bwino kulimba ndi moyo wautumiki wa zinthu zachikopa, komanso kudzera mu mphamvu yotsutsana ndi kuwala kwa chitosan, kukonza magwiridwe antchito apadera, monga kuteteza kuwala kwa chikopa pazovala zoteteza ndi zida zina zotetezera, kugwiritsa ntchito bwino zinthuzi kuli ndi mwayi wabwino wogwiritsa ntchito.
Chachitatu, ma microfiber opangidwa ndi bio ali ndi kapangidwe koyenera, amagwiritsidwa ntchito m'njira zosiyanasiyana, ali ndi mphamvu zambiri komanso satha kuwonongeka, komanso ali ndi phindu labwino komanso phindu lokwezedwa.
