Sažetak
Ovaj istraživački rad opisuje prednosti bojenja vunenih vlakana na 60 °C nakon predobrade alkoholom. Vuna je prirodno vlakno. Ovo vlakno se može bojiti kiselim, metalkompleksnim i drugim bojama. Kisele boje su rastvorljive u vodi i najčešće se koriste za bojenje vune, svile i najlona. U radu su korišćena vunena vlakna 100% hemijskog sastava. Vuneno vlakno je prethodno obrađeno alkoholom (n-pentanol) na temperaturi od 60 °C tokom 30 minuta. Prethodno obrađena vunena vlakna su obojena bojom Supramin Blau - kisela boja. Vreme bojenja uzoraka vunenih vlakana iznosilo je 5, 10, 20, 30, 40, 50 i 60 minuta. Proces bojenja vunenih vlakana kiselom bojom na 60 °C pokazao je veći stepen iscrpljenosti i kapaciteta adsorpcije kada je vuna prethodno obrađena n-pentanolom u poređenju sa vunom koja nije prethodno obrađena n-pentanolom. Uočeno je konstantno povećanje stepena iscrpljenosti boje na prethodno obrađenom vunenom vlaknu tokom povećanja početne koncentracije boje. Duže vreme bojenja za prethodno obrađenu vunu dovodi do većeg iscrpljivanja boje. Modeli Weber-Morris i Elovich su primenljivi za opisivanje toka adsorpcije jer postoji vrlo malo rasejanja oko idealne krive, tako da funkcionalne prave linije veoma dobro pokrivaju većinu tačaka.
