Umuhanga mu guhanga irangi ry'umwijima, Uburyo bwiza bwo kuringaniza ibidukikije n'imikorere yabyo.

Mu rwego rwo gushaka irangi ryiza no guteza imbere iterambere rirambye muri iki gihe,irangi ry'umukara rya aside 2Kubera imbaraga zayo nziza zo gusiga irangi, imikorere yayo ihamye n'imiterere yayo yo kurinda ibidukikije, iba igisubizo cyo guhanga imyenda, tapi n'ibikoresho byihariye ku isi cyo gusiga irangi. Ibicuruzwa byacu bishobora guha abakiriya bacu agaciro gakomeye, gatanga irangi ritangiza ibidukikije kandi rigahangana.

Irangi ry'aside n'umukaraNk’igice cy’irangi rya aside azo ebyiri, ririmo amatsinda ya aside sulfonic mu miterere ya molekile, rishobora kwihuta cyane kandi rikora poroteyine nk’ubwoya, silk na polyamide fibre (nylon), rigera ku ngaruka nini z’umukara wijimye. Mu irangi ry’umukara, aside black 2 ihendutse cyane, cyane cyane ikwiriye gukorwa mu myenda n’amatapi byo mu rwego rwo hejuru, kandi nta gicuruzwa cyuzuye gihari.

Duhitamo impamvu y'irangi ry'umukara rigizwe n'aside, atari gusa ko ari urwego rwo hejuru rw'umukara mwinshi: imiterere ya azo ebyiri bitewe n'umukara umwe, ikwiriye ubwoya, silk, nylon n'izindi poroteyine na polyamide, ihura n'ibyifuzo by'imyenda ikomeye kandi ihenze, imyenda yo mu rugo igezweho. Hariho kandi uburinganire bw'amabara manini: rishobora gushyirwa mu buryo bworoshye hamwe n'irangi ry'ubururu butukura, umutuku n'andi mabara, rigatuma byoroshye kubona urwego rw'amabara menshi kuva ku ivu ry'amakara kugeza ku ibara ry'umukara gusa, bigafasha abashushanya guhanga mu buryo bworoshye.

Niba ukeneye kandi irangi, ibicuruzwa byacu ntibizagutenguha. Ibicuruzwa byacu birahendutse, bifite ubwiza buhebuje, kandi bizaguha uburambe bwiza.
