Zviratidzo zvakakosha zvekuongororwa kwemhando yemabhegi emudzidzi zvinosanganisira kubereka huremu, deformation, kusona simba, kukurumidza kwemavara kune kupokana, kuchengetedzwa kwezviwanikwa, uye formaldehyde zvemukati zvemachira emidziyo. Mukuwedzera, kutarisa kunofanira kubhadharwa kune kunyaradzwa kwemashure paunenge uchishandisa bhegi, pamwe nekureruka kwekushandiswa kwebhanhire remabhegi uye zvibato.
Pamusoro pekutaura nezvekuongororwa kwemukwende, kune akati wandei mapoinzi ekubhadhara zvakanyanya mukuongororwa kwebhegi. Izvo zvinodikanwa zvakasiyana zvishoma: zvinodikanwa zvekutaridzika - chimiro chechimiro chebhegi chinofanirwa kuenderana nemitemo inotevera: kutaridzika kwese, chimiro chakazara, mitsara yakajeka, flat and smooth adhesion, yakarurama, uye hutsanana hwose. Zipper, ine kuchinjika kumucheto, kusona kwakatwasuka, kusina mazino anoshaikwa kana kushaikwa, uye kudhonza nekuvhara kwakatsetseka. Zvishandiso uye kuisirwa kunofanirwa kuve nenzvimbo yakatsetseka, inopenya uye isina ngura inosara, yakapotsa plating, maburi etsono, mablistering, peeling, uye dhizaini. Zvishandiso zvinofanira kuiswa zvakasimba. Mitsara yeSuture inofanira kunge yakakodzera kuhutano hwemucheka uye jira rinoshandiswa, nemhando uye ruvara runoenderana nechikamu chimwe nechimwe. Jira racho harifanire kunge riine wap kana weft rakadambuka, uye harifanire kusvetuka shinda, shinda, mavanga, mavara, kana makwapa. Kudhinda kutaridzika kunoda mapatani akajeka, mavara akajeka, kudhindisa kwakaringana, hapana inoyerera kana yakafumurwa inki, uye hapana ruvara runopera. Suture stitches inofanira kuenderana nepamusoro uye pasi shinda, ine mitsetse yakatwasuka uye inopindirana tsono spacing. Misono isina chinhu kana misono yakapfava haitenderwi kumberi hombe nebutiro rebhegi rebhuku. Hapana kusonwa kwakamisikidzwa kunodarika 12mm pakureba kunobvumidzwa. Chigadzirwa chimwe chete hachifanirwe kuva netsono inopfuura imwe isina chinhu kana tsono inoshaikwa, uye isingapfuuri tsono mbiri dzisina chinhu, tsono dzinoshaikwa, kana tsono dzakasvetuka.
