I-Kinetics yokudaya
Ngexesha lenkqubo yokudaya, idayi idluliswa ukusuka kwidayi ukuya kwifiber.Inkqubo yokudaya ibandakanya ubuncinci izigaba ezithathu, naziphi na ezinokulawula isantya sokudaya kunye nesiphumo sokudaya.:
1. Ukuhanjiswa kwedayi kwibhafu yokudaya ukuya kwifiberumphezulu.
2. I-Adsorption ye-molecule yedayi kwi-fiberumphezulu.
3. Ukusasazwa kwedayi ukusuka kumphezulu ukuya ngaphakathi kwi-fiber.
Kwezinye iimeko, njenge-azoic, i-metallisable, i-vat, isulfure okanye idayi esebenzayo, imolekyuli yedayi iphinda iphendule kunye okanye kwifi.beremva kokusabalalisa, okunokuthi kuthathwe njengesigaba sesine. Kwimeko yokusabalalisa idayi, kwakhona kwimeko ye-vat kunye ne-sulfur dyes, ukuchithwa kwedayi yedayi kuyinyathelo elifunekayo ngaphambi kokuba ukusabalalisa kwenzeke. Igama elithi 'adsorption' libhekisa kumphezulu wesenzeko. Xa kujongwe ukubhekisa nokuba akukho nyathelo lithile lenkqubo yokudaya okanye kuwo onke amanyathelo ngaxeshanye, igama elithi sorption likhethwayo.
Ukubonelela ngengcaciso yenkqubo yokudaya esekelwe kwimithetho ye-physicochemical, iimodeli ezahlukeneyo ziye zaphuhliswa. Ekubeni ukudaya kuntathu okanye, kwimeko yolunye uhlobo lwedayi, inkqubo yezigaba ezine okanye ezihlanu kwaye njengoko inqanaba ngalinye linokunciphisa umlinganiselo wokunyuswa kwedayi, imodeli yemathematika ejolise ekulinganisani onke amanyathelo okuhanjiswa kwedayi iya kuba yinto entsonkothileyo. Nye. Ke ngoko kudla ngokucingelwa ukuba linyathelo elinye kuphela okanye amabini amisela isantya sisonke kwaye imodeli igxile kwezi. Njengothutho lwedayi ngokusasazwa ngaphakathi kwifiberihlala icotha kuwo onke amanyathelo, isembindini wemizekelo emininzi. Xa kungekho mifuziselo yephysicochemical ekhoyo, ubudlelwane beempirical buhlala busetyenziswa.
