Walaxda caddaymaha ee fluorescent waa nooc ka mid ah iskudhis organic ah oo wanaajin kara cadaanka ah ee ka samaysan fiber-ka iyo waraaqaha, sidoo kale loo yaqaan wakiilka caddaynta indhaha iyo wakiilka caddaynta fluorescent.Dharka, iwm ayaa badanaa ah jaale sababtoo ah ku daridda wasakhda midabka leh, iyo bleaching kiimikaad ayaa loo isticmaali jiray in midabkooda laga dhigo waagii hore.Habka wax lagu caddeeyo alaabta ayaa hadda la qaatay, shaqadeeduna waa in loo beddelo shucaaca ultraviolet ee aan la arki karin ee uu nuugo alaabtu u beddelo shucaac buluug-violet ah, kaas oo kaabaya shucaaca asalka ah ee iftiinka jaalaha ah oo noqda iftiin cad, kaas oo noqda iftiin cad. waxay wanaajisaa awoodda alaabta ee u adkeysiga iftiinka qorraxda.oo cadcad.Iftiiminta ayaa si weyn loogu isticmaalay dunta, warqadaha, budada dhaqida, saabuunta, caagga, balaastikada, midabada iyo rinjiga.
Brighteners dhamaantood waxay leeyihiin habab iskuxiran oo iskuxiran oo qaabdhismeedka kiimikada ah, sida: stilbene derivatives, derivatives phenylpyrazoline, derivatives benzothiazole, derivatives benzimidazole, derivatives coumarin iyo Naphthalimide derivatives, iwm, ka mid ah kuwaas oo wax soo saarka ugu weyn.Isticmaal hababka iyo guryaha si aad u kala qaybiso dhalaaliyeyaasha waxaa loo qaybin karaa afar nooc:
Taxanuhu waxa uu tilmaamayaa maaddooyinka caddeeya fluorescent kuwaas oo dhalin kara cations xal aqueous ah.Ku habboon caddeynta fiilooyinka akriliga.Iftiiminta indhaha ee taxanaha B waxay ku habboon yihiin iftiiminta fiilooyinka cellulose.Taxanaha C waxa loola jeedaa nooc ka mid ah wakiilka caddaynta fluorescent ku kala firdhiyey qubeyska dheeha joogitaanka kala firdhiso, ku haboon caddeeyo polyester iyo fiilooyinka kale ee hydrophobic.Taxanaha D waxaa loola jeedaa wakiilka caddeynta fluorescent ee ku habboon fiber borotiinka iyo naylon.Marka loo eego qaab dhismeedka kiimikada, wakiilada caddeynta waxaa loo qaybin karaa shan qaybood: ① nooca stilbene, oo loo isticmaalo suufka suufka ah iyo qaar ka mid ah fiilooyinka synthetic, samaynta waraaqaha, samaynta saabuunta iyo warshadaha kale, oo leh fluorescence buluug;② nooca coumarin, oo leh udgoon Qaab dhismeedka aasaasiga ah ee ketone bean, oo loo isticmaalo balaastikada polyvinyl chloride, iwm, waxay leedahay fluorescence buluug xoog leh;③ Nooca pyrazoline, oo loo isticmaalo dhogorta, polyamide, fiilooyinka acrylic iyo fiilooyinka kale, oo leh fluorescence cagaaran;④ nooca benzoxazine, oo leh Fiilooyinka acrylic iyo balaastikada kale sida polyvinyl chloride iyo polystyrene, waxay leedahay fluorescence cas;Nooca phthalimide, oo loogu talagalay polyester, acrylic, naylon iyo fiilooyinka kale, oo leh fluorescence buluug ah.Kuwa kore waa kala soocida wakiilada caddeynta.Marka ay macaamiishu dooranayaan wakiilada caddeynta, waa inay marka hore fahmaan alaabtooda, si ay u doortaan wakiilka saxda ah ee nadiifinta.Macaamiishu waa inay sidoo kale ogaadaan in marka la isticmaalayo walxaha caddaynta, wakiilada caddaymaha ay yihiin oo kaliya iftiinka indhaha iyo midabada dhammaystirka ah, oo aan bedeli karin kiimikada bleaching.Sidaa darteed, arrinta midabka leh waxaa si toos ah loogu daaweeyaa walaxda caddeynta iyada oo aan bleaching lahayn, iyo saameynta caddeynta lama heli karo asal ahaan.Wakiilka caddaymaha ma aha mid aad u cadcad, laakiin wuxuu leeyahay feejignaan saturation gaar ah.Ka gudubka qiimaha xaddidan ee go'an, ma aha oo kaliya saameyn caddaan ah, laakiin sidoo kale jaale.
