Denim imyenda irangi hamwe na Sulfure Black BR irazwi cyane.Ibikoresho byo gusiga amarangi dukoresha bifata uburyo bwo gukomeza gucapa no gusiga irangi ryintambara, kandi umusaruro urakuze.Amazi yumukara BR ntashonga mumazi, ariko, irashobora gushonga mumuti wa sodium sulfide mugusubira mubara ryihishe.Uyu mubiri wibara ryihishe urashobora gusiga irangi kuri fibre selile kugirango urangize irangi.Ibiranga amarangi ya sufuru asa naya marangi ataziguye n'amabara ya vat.Isubiranamo rya Sulfure Black BR, sodium sulfide, ifite kugabanuka guke, ntabwo rero byoroshye ko umukara wa sulfure ugabanuka.Muri icyo gihe, Sufuru Yirabura BR ihagaze neza ku bushyuhe bwinshi.Iyo irangi ry'umukara wa BRU ryagabanutse kandi rigashonga hamwe na sodium sulfide, ribyara thiophenol, ihinduka sodium sulfide ikanashonga.
Umuti w'irangi ugizwe n'amabara ya sulfuru yagabanijwe na sodium sulfide ntabwo ihagaze neza bihagije.Irangi ryirabura rya Sufuru ryirabura rigomba gukaraba neza kugirango rikureho sodium sulfide isigaye kumyenda kandi irashobora guhumeka neza numwuka.Ingano ya sodium sulfide ikoreshwa mu kugarura no gushonga Sulfure Black BR ntishobora kubarwa neza.
Nyuma yo gusiga fibre hamwe n irangi ryumukara wa BR BR, igomba kuba oxyde kugirango ihinduke irangi ridashonga kandi igashyirwa kuri fibre.umukara wa sulfure urashobora kuba okiside mugihe cyose wogejwe kandi ugahumeka.Iyo irangi ryirangi hamwe nigipimo cyihuta cya okiside yumuvuduko wa leuco, niba irangi ryahuye numwuka cyangwa sodium sulfide idahagije, bizahinduka okiside igihe kitaragera kugirango bitange ikizinga.Amabara atari umukara wa sulfuru arashobora kuvurwa hamwe nogukosora kugirango amabara yihute.Sulfate y'umuringa irashobora guhagarika fibre yoroheje ya Sulfure Black BR, bityo sulfate y'umuringa ntishobora gukoreshwa mugukosora.
