Umehluko omkhulu phakathi kwama-pigment nama-dyes ukusetshenziswa kwawo. Ama-dyes asetshenziswa kakhulu ezindwangu, kanti ama-pigment ikakhulukazi angewona ama-textile.
Isizathu sokuthi imibala namadayi ahluke ngoba imibala ine-affinity, engaziwa nangokuthi iqondile, ngoba izindwangu namadayi angamuncwa futhi alungiswe ngama-molecule e-fiber; Ama-pigment awanayo i-affinity yazo zonke izinto ezinemibala, ikakhulukazi ethembele kuma-resin, ama-adhesive, njll. ukuze afake imibala emikhiqizweni. Amadayi agcizelela ukucaca futhi ngokuvamile anokukhanya okuhle; Ama-pigment agcizelela izakhiwo zokumboza futhi ngokuvamile anokuqina okuhle.
Kunezinhlobo ezintathu ezahlukene zombala kanye nodayi:
Umehluko wokuqala phakathi kwama-pigment namadayi yi-Different Solubility. Umehluko oyinhloko phakathi kwama-pigment namadayi ukuncibilika kwawo. Njengoba kwaziwa kahle, ama-pigment awancibiliki koketshezi, kuyilapho amadayi engancibilika ngqo koketshezi olufana namanzi, i-asidi, njalo njalo.
Umehluko wesibili phakathi kwama-pigment namadayi usezindleleni zabo ezahlukene zokufaka imibala. I-pigment iyinto enombala oyimpuphu edinga ukuthululwa oketshezini ngaphambi kokufaka umbala. Nakuba ingeke ibole futhi incibilike oketshezini, izohlakazeka ngokulinganayo. Ngemva kokuxubha ngokulinganayo, abasebenzisi bangaqala ukufaka umbala ngebhulashi. Indlela yokufaka imibala yamadayi iwukuwathela oketshezini, balinde ukuthi ancibilike ngokuphelele oketshezini, bese befaka ibhulashi oketshezini ukuze idaywe, bese bekhipha ibhulashi ukuze baxube ngqo bese befaka umbala.
Umehluko wokugcina phakathi kwama-pigment nama-dyes ukusetshenziswa okuhlukile. Ngemva kokufunda umehluko omibili ongenhla, ake sibheke umehluko wokugcina, okuwukusetshenziswa kwawo. Ama-pigment asetshenziswa kakhulu ekumbozeni, kuyinki, ekunyatheliseni nasekudayeni, njll.; Ama-dyes, ngakolunye uhlangothi, avame ukusetshenziswa ezintweni zefayibha, ubunjiniyela bamakhemikhali, noma ekuhlobiseni isakhiwo.
Amakhasimende angakhetha imibala noma amadayi ngqo lapho ethenga.
