Mumakore achangopfuura, vanhu vari kuramba vachinyanya kutarisisa hutano nekuchengetedzwa kwezvakatipoteredza, uye faibha yemiti yave kufarirwa zvakanyanya. Faibha yebhanana yave ichinyanya kutariswa neindasitiri yemachira.
Bhanana ndeimwe yemichero inodiwa nevanhu, inozivikanwa se "muchero unofadza" uye "chibereko cheuchenjeri". Kune nyika 130 dzinorima mabhanana pasi rose, ine kugadzirwa kukuru muCentral America, ichiteverwa neAsia. Zvichienderana nehuwandu, matani anopfuura mamiriyoni maviri emiti yebhanana inoraswa gore rega rega muChina chete, izvo zvichikonzera kutambisa zviwanikwa zvakanyanya. Zvisinei, mumakore achangopfuura, miti yemiti yebhanana haicharaswi, uye kushandiswa kwemiti yemiti yebhanana kubvisa fiber yejira (bhanana fiber) kwave nyaya inonyanya kutaurwa.
Fibre yebhanana inogadzirwa netsvimbo yebhanana, inonyanya kuumbwa ne cellulose, semi-cellulose uye lignin, iyo inogona kushandiswa pakuruka donje mushure mekubviswa kwemakemikari. Uchishandisa nzira yekurapa yakabatana ne enzyme ye biological uye chemical oxidation, kuburikidza nekuomesa, kunatswa, uye kuora, fiber iyi ine chiedza chemhando yepamusoro, kupenya kwakanaka, inonyudzwa zvakanyanya, ine antibacterial yakasimba, inoparadza nyore nyore uye inochengetedza nharaunda nezvimwe zvakawanda.
Kugadzira machira nebhanana fiber hakusi chinhu chitsva. MuJapan pakutanga kwezana remakore rechi13, kugadzirwa kwefaibha kwaigadzirwa kubva mumiti yemabhanana. Asi nekukwira kwedonje nesirika muChina neIndia, tekinoroji yekugadzira machira kubva mumabhanana yakanyangarika zvishoma nezvishoma.
Fibre yebhanana ndeimwe yefiber dzakasimba kwazvo pasi rose, uye fiber iyi yechisikigo inoora inogara kwenguva refu.
Fiber yebhanana inogona kugadzirwa kuita machira akasiyana zvichienderana nehuremu hwakasiyana uye ukobvu hwezvikamu zvakasiyana zvehunde dzakasiyana dzebhanana. Fiber yakasimba uye yakakora inotorwa kubva muchikamu chekunze, nepo chikamu chemukati chichitorwa zvakanyanya kubva muhutete hwakapfava.
Ndinotenda kuti munguva pfupi iri kutevera, tichaona mhando dzese dzebhanana dzakagadzirwa nembatya muzvitoro.
