Bitewe n’uko abaguzi barushaho gushakisha ubwiza bw’imyenda, ibara ry’imyenda naryo ririmo guhinduka kuva ku ngiro kugeza ku shya.
Guhindura ibara ry'ibikoresho bya fibre hifashishijwe ikoranabuhanga rigezweho kandi rishya, kugira ngo ibara cyangwa imiterere y'imyenda ihinduke urumuri, ubushyuhe,
Ubushuhe buhinduka kuva ku "busanzwe" bujya ku "buhinduka" bugaragara, mu rwego rw'imyenda
Ku iterambere ryihuse no gukoreshwa mu buryo bwagutse.
Ibikoresho bihindura amabaraubwoko n'uburyo bwo guhindura amabara *
(1) ibikoresho bishobora kwanduza imirasire y'izuba
Uburyo bwo guhindura ibara ry’urumuri bushobora kubaho bitewe n’imirasire ya ultraviolet cyangwa urumuri rugaragara, kandi bushobora kuzimira nyuma y’urumuri.
Hindura ukoreshe ibara ry'umwimerere. Ibikoresho byo guhindura ibara ry'ibara ry'izuba ahanini ni chloride y'ifeza, bromide y'ifeza, stilbene
Icyiciro, itsinda rya spiral ring, itsinda rya nornadiene, itsinda rya capture refined anhydride, triphenylmethane derivatives, itsinda rya aside salicylic aniline
Ibikubiye muri ibyo, nibindi. Kuri ubu, ibikoresho bihindura amabara by’umwimerere byakozwe kugira ngo bigire amabara 4 y’ibanze: umuhengeri, umuhondo, ubururu n’umutuku.
Imiterere y'ibanze y'ubwoko bwose bw'ibikoresho bifotora ni ubwoko bw'urukiramende rufunze, ni ukuvuga ko nta bara ryanditse ku mwenda, ahubwo rihinduka gusa iyo imirasire ya ultraviolet ikoze.
Umutuku wijimye, umuhondo, ubururu, umutuku.
(2) ibikoresho bifatwa n'ubushyuhe
Impamvuibikoresho bihindura amabara bikoresha thermosensitivebishobora guhindura ibara biterwa nuko ibara rishobora gutera impinduka mu miterere y'imbere, bigatera impinduka mu ibara, iyo ubushyuhe bugabanutse, ibara riragaruka. Ugereranyije n'amabara akoresha foto, ubushakashatsi ku marangi akoresha ubushyuhe mu gihugu no mu mahanga ni bwinshi cyane, cyane cyane mu ikoreshwa ry'imashini zicapa imyenda, bwageze ku musaruro runaka, hasohotse urutonde rw'ibikoresho byo gucapa bikoresha ubushyuhe.
