Udayi oncibilikayo
Udayi oncibilikayo uwudayi oncibilika kuzincibilikisi zemvelo futhi ovame ukusetshenziswa njengesixazululo kulezo zincibilikisi.Lesi sigaba sikadayi sisetshenziselwa ukufaka imibala ezintweni ezinjengamawaksi, okothambisa, amapulasitiki, nezinye izinto ezingezona ezomhlaba ezisekelwe ku-hydrocarbon.Noma imaphi amadayi asetshenziswa kumafutha, isibonelo, angathathwa njengamadayi ancibilikayo futhi awancibiliki emanzini.

Hlukanisa odayi
I-Disperse dye uhlobo olulodwa lwento ephilayo engenawo ama-ionizing group.Ayincibiliki kancane emanzini futhi isetshenziselwa ukudaya izinto zokwenziwa zendwangu.Odayi abahlakazayo bathola imiphumela yabo engcono kakhulu lapho inqubo yokufa yenzeka emazingeni okushisa aphezulu.Ikakhulukazi, izixazululo ezingaba ngu-120°C kuya ku-130°C zinika amandla odayi abahlakazayo ukuthi basebenze kumazinga abo afanele.
I-Hermeta ihlinzeka ngodayi abahlakazayo ngamasu ahlukahlukene wokufaka imibala kokwenziwa njenge-polyester, inayiloni, i-cellulose acetate, i-vilene, ama-velvets okwenziwa kanye ne-PVC.Umthelela wabo awunamandla amancane ku-polyester, ngenxa yesakhiwo samangqamuzana, okuvumela i-pastel kuphela ukuya ku-shades ephakathi, nokho umbala ogcwele ungafinyelelwa lapho ukuphrinta kokushisa okushisayo ngamadayi ahlakazayo.Odayi be-Disperse nabo basetshenziselwa ukuphrinta i-sublimation yemicu yokwenziwa futhi bayimibala esetshenziswa ekwakheni amakhrayoni noyinki okudlulisa "i-iron-on".Zingasetshenziswa futhi kuma-resin namapulasitiki ukuze kusetshenziswe umbala ongaphezulu nokujwayelekile.

Amadayi Ensimbi Eyinkimbinkimbi
Udayi oyinkimbinkimbi wensimbi uwumndeni wamadayi aqukethe izinsimbi ezididiyelwe engxenyeni yezinto eziphilayo.Amadayi amaningi e-azo, ikakhulukazi lawo atholakala kuma-naphthols, enza izingxube zensimbi ngokuhlanganiswa kwesinye sezikhungo ze-azo nitrogen.Odayi bensimbi abayinkimbinkimbi bangamadayi angaphambi kwe-metallised abonisa ukuhlobana okukhulu kumafayibha amaprotheni.Kulo dayi i-molecule eyodwa noma amabili kadayi ahlanganiswa ne-ion yensimbi.I-molecule kadayi ngokuvamile iyisakhiwo se-monoazo esiqukethe amaqembu engeziwe njenge-hydroxyl, i-carboxyl noma i-amino, ekwazi ukwenza izakhiwo eziqinile zokuhlanganisa nama-ion ensimbi aguqukayo njenge-chromium, i-cobalt, i-nickel nethusi.
