Amabara meza (ni ukuvuga: inkingi ya sublimation y'ibicuruzwa by'ipamba) ni amarangi akoreshwa cyane mugusiga amarangi, ibicuruzwa bizamuka cyane, bikaba biteganijwe kandi ko bizakomeza mumyaka mike iri imbere.Ibyamamare byamabara adasanzwe biterwa nigiciro cyacyo giciriritse, imbaraga zo gusiga hejuru hamwe nubwiza bwamabara meza.Gusa ibibi byayo ni ikibazo cya hydrolysis yibintu byo gusiga.

Ibisobanuro bya Hydrolysis

Amabara asanzwe ashyirwa kuri fibre ya pamba mugihe cya alkaline, kandi alkalinity iteza reaction hagati yibintu byo gusiga irangi n'amazi, kugirango irangi ritakaza ibikorwa.Hamwe n amarangi adakora (noneho ni nkamabara ya hydrolyzed), ntashobora kwitwara hamwe nudusimba twa pamba (Rimwe niba ibicuruzwa byacu ari amasogisi ya pamba), bikaviramo gutakaza amarangi igice.Amabara ya Hydrolyzed yumubiri yumubiri kumpamba kugeza igihe yogejwe mugihe cyo gukaraba, niyo mpamvu isohoka nyuma hamwe nikibazo cyihuta cyamabara.Mubyongeyeho, amarangi ya hydrolyzed nayo yinjira mumazi yimyanda & kongera umutwaro wumwanda.

Imyitwarire yamabara meza namazi ntabwo arimpamvu yonyine yo guhindura ibara ryinshi.Imikorere yo gusiga irangi nayo ifitanye isano rya hafi ningingo zikurikira, nko guhunika ububiko, guhagarara kwamazi yo kumeneka cyangwa gucapura, ndetse no guhindura irangi ryibara ryibara ryibikorwa muburyo bwo gusesa amashyanyarazi.

Nyuma yintangiriro yo gusiga amarangi na hydrolysis.Ugomba noneho gusobanukirwa neza nigisubizo hagati ya wino yo gucapa hifashishijwe ibicuruzwa bya fibre.Niba ushishikajwe niyi ngingo, twandikire.
