Aluminium Sulfate, e nang le foromo ea lik'hemik'hale Al2(SO4)3, eo hape e tsejoang e le alum, ke motsoako o qhibilihang ka metsi o bapalang karolo ea bohlokoa lits'ebetsong tsa tlhahiso ea masela ka lebaka la thepa ea eona e ikhethang le sebopeho sa lik'hemik'hale. E 'ngoe ea lisebelisoa tsa eona tsa mantlha ke ho daea le ho hatisa masela. Aluminium sulfate e sebetsa e le mordant, e thusang ho lokisa dae ho likhoele, ka tsela eo e matlafatsa ho potlaka ha mebala le ho ntlafatsa boleng ba kakaretso ea lesela le dailoeng. Ka ho etsa li-complexes tse sa tsitsang ka li-dae, li-alum li tiisa hore li boloka lesela, li thibela ho tsoa mali le ho fela nakong ea ho hlatsoa ka mor'a moo.
Ho feta moo, aluminium sulfate e sebelisoa ha ho etsoa mefuta e itseng ea lidae tsa mordant, tse kang oli e khubelu ea Turkey. Lidae tsena, tse tsejoang ka mebala ea tsona e khanyang le e tšoarellang nako e telele, li sebelisoa haholo indastering ea masela bakeng sa ho daea k'hothone le likhoele tse ling tsa tlhaho. Ho eketsoa ha alum ho bateng ea dae ho thusa ho tlama limolek'hule tsa dae lesela, e leng se etsang hore ho be le mebala e ts'oanang le ho ntlafatsa ho potlaka ha ho hlatsoa.
Ntle le karolo ea eona ea ho daea, aluminium sulfate e fumana ts'ebetso ho boholo ba masela, ts'ebetso e reretsoeng ho matlafatsa matla, boreleli le ho sebetsana le thepa ea likhoele le masela. Lisebelisoa tsa sizing, tse atisang ho etsoa ka starch kapa li-polymers tsa maiketsetso, li sebelisoa holim'a likhoele ho fokotsa likhohlano le ho robeha nakong ea ho loha kapa ho loha. Aluminium sulfate e sebelisoa e le coagulant ha ho lokisoa liforomo tsa boholo tse thehiloeng ho starch. Ka ho khothaletsa ho bokellana ha likaroloana tsa starch, alum e thusa ho fihlela boemo bo tšoanang ba boholo ba lesela, bo lebisang ho ntlafatseng ho loha le boleng ba lesela.
Ho feta moo, aluminium sulfate e sebelisoa ho hloekisoa le ho hloekisoa ha masela, haholo-holo likhoele tsa k'hothone. Ho hloekisa ke mokhoa oa ho tlosa litšila, tse kang boka, li-pectins le oli ea tlhaho, ho tloha holim'a lesela ho etsa hore dae e kenelle hantle le ho khomarela. Aluminium sulfate, hammoho le li-alkali kapa li-surfactants, li thusa ho emola le ho qhala litšila tsena, e leng se etsang hore ho be le likhoele tse hloekileng le tse monyang haholoanyane. Ka mokhoa o ts'oanang, ha ho etsoa desizing, alum e thusa ho senyeha ha lisebelisoa tse thehiloeng ho starch tse sebelisoang nakong ea ho lokisoa ha likhoele, kahoo li lokisa lesela bakeng sa ho daea kapa ho qeta phekolo.
Ntle le moo, aluminium sulfate e sebetsa e le coagulant lits'ebetsong tsa kalafo ea metsi a litšila ka har'a limela tse etsang masela. Mokelikeli o hlahisoang ke mesebetsi e fapaneng ea masela hangata o na le lintho tse tiileng tse fanyehiloeng, li-colorants, le lintho tse ling tse silafatsang, tse bakang mathata a tikoloho haeba a sa laoloe. Ka ho eketsa alum ho metsi a litšila, likaroloana tse emisitsoeng lia senyeha 'me li kopantsoe, li nolofalletsa ho tlosoa ha tsona ka ho qhibiliha kapa ho hloekisa. Sena se thusa ho fihlela ho tsamaellana le litekanyetso tsa taolo le ho fokotsa tšusumetso ea tikoloho mesebetsing ea tlhahiso ea masela.
Qetellong, aluminium sulfate e bapala karolo e fapaneng indastering ea masela, e kenya letsoho ho daeng, ho siling, ho kolobisa, ho etsa desizing, le lits'ebetsong tsa ho hloekisa metsi a litšila. Ho sebetsa ha eona joalo ka mordant, coagulant, le thuso ea ho sebetsa e totobatsa bohlokoa ba eona ts'ebetsong ea tlhahiso ea masela.
