Mafashoni Oyera Kuwonetsa Bokosi la ndudu (chilichonse) mabokosi 10, bokosi lililonse la ma phukusi 7

Makatoni oyera ndi mtundu wa pepala lolimba ndi kulimba komanso kulemera kwakukulu. Chifukwa pamwamba si utoto, umatchedwa makhadi oyera. Makatoni oyera a China agawidwa m'makalasi atatu a, B, C. kuyeretsedwa kwa kalasi sikochepera 92%; B grad siochepera 87%; C grade si yochepera 82%.
Zopangira zoyera za makatoni oyera ndi 100% yophatikizika
Khadi Loyera la Mapaketi a ndudu limafunikira kuuma kwambiri, kukana, kukana ndi kuyera. Zofunikira zapamwamba ndizosalala, palibe mikwingwirima, mawanga, mabulupe ndi ma bapts, akutentha ndi kusinthika kwa kupanga. Monga paketi ya ndudu yokhala ndi mabokosi oyera makamaka pogwiritsa ntchito makina osindikizira osindikizira osindikizira kuti musindikize, kotero kuti makhadi oyera a masheya a mesx ndi okwera. Kukanana nkhawa kumadziwikanso kuti mphamvu zakumimba kapena mphamvu, zomwe zimatanthawuza zovuta zomwe pepalalo limatha kupirira pomwe limasweka, lofotokozedwa ku K Kin / M. Makina osindikizira osindikizira osindikizira kuti akokere mapepala, kusindikiza kwambiri kwambiri kuti athe kuthana ndi mavuto akulu, ngati chodabwitsa cha kubereka kwa pepala nthawi zambiri, chimakhala nthawi yayitali, komanso kuwonjezera pepala.
Pali mitundu iwiri ya makatoni oyera a ndudu, imodzi ndi khadi yoyera yoyera), imodzi ndi sbssing ndi masamba atatu osanjikiza makina opanga mitengo yopukutira nkhuni zamkati. Mbali yakutsogolo (mbali yosindikiza) ndi yophimba, yomwe imagwiritsidwa ntchito ndi ziwiri kapena zitatu zopindika, pomwe mbali yosinthira ilibe kukula. Popeza kutalika kwa mkati kumapangidwa ndi mitengo yamankhwala ndi makina ali ndi zokolola zambiri zokolola (85% -90%), ndipo mtengo wopanga wa Fbb ali wotsika kwambiri.
Fbb zamkati uli ndi ulusi wotalika kwambiri ndi ulusi wocheperako ndi mitolo ya fiber, kotero makulidwe omwe ali pamwambawa ndi abwino kwambiri, ndipo nthawi zambiri imaphatikizika kwambiri, ndipo nthawi zambiri imapangidwanso ndi ma sbs omwe amagwiritsidwa ntchito kwambiri Mbali yakutsogolo (kusindikizidwa) ndi yophimba kawiri, yomwe imagwiritsidwa ntchito kawiri kapena katatu ndi yofanana ndi FBB, pomwe mbali yosinthira ilibe kukula. Popeza pakati pa core amapangidwanso ndi zamkati wa sulfate, kuyera kwake ndikokwera, motero amatchedwa ridi yoyera yoyera. Nthawi yomweyo, ulusi wamtunduwu ndi wocheperako ndipo pepalali ndi lopepuka, kotero SBs ndi yowonda kwambiri kuposa fbb yolemera yomweyo. Mwachitsanzo, makulidwe a 230g / m2 fbb wa Hongta Renheng ndi 320μm, pomwe makulidwe a 230g / m2 ndi 295μm.
