Kufotokozera mwatsatanetsatane ulusi wosokera

Ulusi wosoka umagwiritsidwa ntchito kusoka mitundu yonse ya nsapato, matumba, zidole, nsalu za zovala ndi zipangizo zina zothandizira, zomwe zimakhala ndi ntchito ziwiri: zothandiza ndi zokongoletsera.Ubwino wa kusoka sikuti umangokhudza kusoka komanso mtengo wokonza, komanso umakhudza mawonekedwe azinthu.Anthu omwe amagwira nawo ntchito yogulitsa zovala ayenera kumvetsetsa lingaliro la kusokera, kupotoza, kugwirizana pakati pa kupotoza ndi mphamvu, magulu a masikisi, makhalidwe ndi ntchito zazikulu, kusankha kwa ulusi ndi zina zomveka.Elastic band wopanga

Awa ndi mawu oyamba achidule:

Choyamba, lingaliro la ulusi wa ulusi (carding) limatanthauza ulusi umene amalukidwa poyeretsa mbali imodzi yokha.Kupesa kumatanthauza ulusi womwe umatsukidwa mbali zonse ziwiri za ulusi ndi makina opesa.Zonyansazo zachotsedwa ndipo ulusi wake ndi wowongoka kwambiri.Kusanganikirana kumatanthauza ulusi umene ulusi uŵiri kapena kuposerapo wokhala ndi zinthu zosiyanasiyana umasakanikirana pamodzi.Ulusi umodzi umatanthawuza ulusi womwe wapangidwa mwachindunji pa chimango chopota, chomwe chimafalikira chikapanda kupindika.Ulusi wokhotakhota umatanthauza ulusi uŵiri kapena kuposerapo womwe umatchedwa kuti ulusi waufupi.Ulusi wosoka umatanthawuza dzina la ulusi womwe umagwiritsidwa ntchito posoka zovala ndi zinthu zina zosokedwa.Kupota kwa kachitidwe katsopano n'kosiyana ndi kupota kwa mphete kwachikhalidwe, ndipo mbali ina imakhala yopumula, monga kupota mpweya ndi kupota mikangano.Ulusiwo umalumikizidwa popanda kupindika.Kuwerengera kwa ulusi kumagwiritsidwa ntchito kusonyeza ubwino wa ulusi, makamaka kuwerengera Chingerezi, chiwerengero cha metric, chiwerengero chapadera ndi chokana.

Chachiwiri, ponena za lingaliro la kupotoza: mutatha kupotoza mawonekedwe a ulusi wa mzerewu, kusuntha kwa angular kumachitika pakati pa magawo a mzere wa mzere, ndipo ulusi wowongoka umayenda ndi axis kuti usinthe mawonekedwe a mzerewo.Kupotoza kungapangitse ulusi kukhala ndi ntchito zina zakuthupi ndi zamakina, monga mphamvu, elasticity, elongation, luster, kumverera kwa manja, ndi zina zotero. Zimasonyezedwa ndi chiwerengero cha zopotoka pa kutalika kwa unit, kawirikawiri chiwerengero cha kutembenuka pa inchi (TPI) kapena chiwerengero cha matembenuzidwe pa mita (TPM).Kupotoza: Madigiri 360 mozungulira mozungulira ndi kupindika.Kupotoza njira (S-direction kapena Z-direction): njira yokhotakhota yozungulira yomwe imapangidwa pozungulira mozungulira ulusiwo ukakhala wowongoka.Njira yokhotakhota yokhotakhota ya S ili pamodzi ndi pakati pa chilembo S, ndiko kuti, kumanja kapena kumanja.Njira yopendekeka ya njira yokhotakhota ya Z ili pamodzi ndi pakati pa chilembo Z, ndiye kuti, mbali yakumanzere kapena yopingasa.Kugwirizana pakati pa kupotoza ndi mphamvu: kupotoza kwa ulusi kumayenderana mwachindunji ndi mphamvu, koma pambuyo pa kupotoza kwina, mphamvu imachepa.Ngati kupindika kuli kwakukulu kwambiri, mbali yokhotakhota idzawonjezeka, ndipo kuwala ndi kumverera kwa ulusi kudzakhala kosauka;Kupindika kwakung'ono, tsitsi ndi kumasuka kwa manja.Izi ndichifukwa choti kupotoza kumawonjezeka, kukana kukangana pakati pa ulusi kumawonjezeka, ndipo mphamvu ya ulusi imakula.Komabe, ndi kuwonjezeka kwa kupotoza, gawo la axial la ulusi limakhala laling'ono, ndipo kugawanika kwa kupsinjika kwa ulusi mkati ndi kunja kumakhala kosagwirizana, zomwe zimayambitsa kusagwirizana kwa fiber cracking.Mwachidule, ntchito yosweka ndi mphamvu ya ulusi imagwirizana kwambiri ndi kupotoza, ndipo kupotoza ndi kupotoza kumadalira zosowa za mankhwala ndi pambuyo pokonza, kawirikawiri Z kupotoza malangizo.
