Fluorescent umweru ni ubwoko bwimvange kama ishobora kuzamura umweru wimyenda ya fibre nimpapuro, bizwi kandi nka optique yera na agent ya fluorescent.Imyenda, nibindi akenshi usanga ari umuhondo kubera gushyiramo umwanda wamabara, kandi guhumanya imiti byakoreshwaga mu kubishushanya kera.Uburyo bwo kongeramo umweru wera kubicuruzwa ubu bwakoreshejwe, kandi umurimo wabwo ni uguhindura imirasire itagaragara ya ultraviolet yakiriwe nibicuruzwa mumirasire yubururu-violet fluorescent, ibyo bikaba byuzuzanya nimirasire yumwimerere yumuhondo kandi bigahinduka urumuri rwera, ibyo itezimbere ubushobozi bwibicuruzwa kwihanganira izuba.cyera.Brighteners yakoreshejwe cyane mumyenda, impapuro, ifu yo gukaraba, isabune, reberi, plastike, pigment hamwe n amarangi.
Brighteners bose bafite sisitemu ya cyclic conjugated mumiterere yimiti, nka: ibikomoka kuri stilbene, ibikomoka kuri fenylpyrazoline, ibikomoka kuri benzothiazole, ibikomoka kuri benzimidazole, ibikomoka kuri coumarin nibikomoka kuri Naphthalimide, nibindi, muri byo ibikomoka kuri stilbene bifite umusaruro mwinshi.Koresha uburyo numutungo kugirango ugabanye ibimurika birashobora kugabanwa muburyo bune:
Urukurikirane rwerekana tofluorescent yera ishobora kubyara cations mugisubizo cyamazi.Bikwiranye no kwera kwa fibre acrylic.B urukurikirane rwa optique rumurika rukwiranye na fibre selile.Urukurikirane rwa C bivuga ubwoko bwa florescent yera yera ikwirakwizwa mubwogero bwamabara imbere yabatatanye, ibereye kwera polyester hamwe nizindi fibre hydrophobique.D urukurikirane rwerekana fluorescent yera ikwiranye na protein fibre na nylon.Ukurikije imiterere yimiti, imiti yera irashobora kugabanywamo ibyiciro bitanu: type ubwoko bwa stilbene, bukoreshwa muri fibre fibre hamwe na fibre synthique, gukora impapuro, gukora amasabune nizindi nganda, hamwe na fluorescence yubururu;Type ubwoko bwa coumarin, hamwe nimpumuro nziza Imiterere yibanze ya ketone yibishyimbo, ikoreshwa muri plastiki ya chloride polyvinyl, nibindi, ifite fluorescence ikomeye yubururu;Type ubwoko bwa pyrazoline, bukoreshwa mu bwoya, polyamide, fibre acrylic nizindi fibre, hamwe na fluorescence yicyatsi;Type ubwoko bwa benzoxazine, hamwe na fibre acrylic nibindi plastike nka polyvinyl chloride na polystirene, ifite fluorescence itukura;Ubwoko bwa phthalimide, kuri polyester, acrylic, nylon nizindi fibre, hamwe na fluorescence yubururu.Ibyavuzwe haruguru ni ugushyira mubikorwa byera.Mugihe abakiriya bahisemo ibikoresho byera, bagomba kubanza kumva ibicuruzwa byabo, kugirango babashe guhitamo umukozi mwiza wo kwera.Kandi abakiriya bagomba kumenya kandi ko mugihe bakoresha ibikoresho byera, ibikoresho byera nibyiza gusa byo kumurika no kuzuza amabara, kandi ntibishobora gusimbuza imiti.Kubwibyo, ibintu byamabara bivurwa muburyo butaziguye no kwera nta guhumeka, kandi ingaruka zo kwera ntizishobora kuboneka muburyo bwiza.Kandi umukozi wera ntabwo arera cyane, ahubwo afite intumbero yo kwiyuzuzamo.Kurenza igipimo ntarengwa cyagenwe, ntabwo ari ingaruka zera gusa, ariko kandi n'umuhondo.
