ziye nongo

Hlakaza iidayi zaye ekuqaleni ukulungiselela bokudaya neselulosi acetate, kwaye ngamanzi-ezingenakunyibilika. Le nongo luyacolwa bayisile xa kukho arhente mabasasazwe kwaye athengiswe abe intlama, okanye yokutshiza-ezomisiweyo kwaye wathengiswa ngumgubo. ukusebenzisa zazo eziphambili kukuba idayi ipholiyesta, kodwa nazo zingasetyenziswa ukuba idayi nenayiloni, neselulosi triacetate, kunye imicu acrylic. Kwezinye iimeko, kufuneka lobushushu bokudaya 130 ° C (266 ° F), kunye dyebath xinzelelo isetyenzisiwe. Ubungakanani yamasuntswana entle kakhulu inika indawo umphezulu enkulu ukuba ezinceda ngamanyala ukuvumela ukufunxeka yi ifayibha. Izinga bokudaya ukuba kakhulu kuchatshazelwa ukukhetha nazisasaza arhente kusetyenziswa ngexesha ngokugaya.

acid nongo

Acid nongo idayi anionic ngamanzi-enyibilikayo ukuba isicelo kwimicu ezifana isilika, uboya, nenayiloni neerhali acrylic walungiswa besebenzisa cala ukuya iibhate umbala asidi. Uncamathiselo kwi ifayibha yayanyaniswa, ubuncinane ngokuyinxenye, ekwakhiweni ityuwa phakathi kwamaqela anionic kwi idayi kunye namaqela cationic kwi ifayibha. Acid nongo akukho neziyinene kwiNdlu kwimicu cellulosic. Uninzi imibala ukutya eyenziweyo kuwa kolu didi.

basic nongo

iidayi ezingundoqo idayi cationic ngamanzi-enyibilikayo ukuba ubukhulu becala izicelo kwimicu acrylic, kodwa ukufumana ezinye ukusetyenziswa ngenxa uboya kunye silk. Kudla acetic acid wongezwa ngokuhlamba idayi ukunceda ukuthathwa le idayi kwi ifayibha. iidayi Basic nazo kusetyenziswa kombala kwephepha.

Vat nongo

iidayi Vat ezibonakala ikakhulukazi ezingenakunyibilika emanzini yaye angakwazi yidayi imicu ngqo. Noko ke, nokuncipha utywala obrak uvelisa metal kwealkali ityuwa emanzini-enyibilikayo le dayi. Le fomu kudla nto enemibala, kukowuphi umzekelo apho ibizwa ngokuba idayi Leuco, kwaye kukho sendiselane kuba ifayibha alukiweyo. ohlaziya igcwala elandelayo idayi yokuqala ezingenakunyibilika. Umbala denim kungenxa indigo, esixovulelweni umbala yokuqala.

Direct nongo

iidayi ngqo eyenziwa ngaphandle kwindawo idayi ibhafu cala okanye ialakalin kancinane, okanye kufutshane indawo abilayo, kongezwe nokuba sodium chloride (NaCl) okanye sodium sulfate (Na2SO4) okanye isodium carbonate (Na2CO3). iidayi ngqo asetyenziswa umqhaphu, iphepha, ngethwathwa, uboya, isilika, kunye nenayiloni. Kananjalo zizsetyenziswa njengezalathisi pH yaye njengoko amabala eziphilayo.

sulfur nongo

iidayi Isalfure na idayi engaxabisi kakhulu asetyenziswa idayi cotton imibala emnyama. Bokudaya lwenziwa ngokufudumeza eli laphu kumxube kukho ulungelelwaniso, ngokokuqhelekileyo yemvelaphi nitrophenol, kunye emanzini okanye polysulfide. Le ulungelelwaniso idityaniswe umthombo emanzini ukwenza imibala emnyama ukuba babambelele laphu. Isalfure Black 1, ezona lokuthengisa idayi ngomthamo, akanayo isakhiwo imichiza echazwe kakuhle.
