Umehluko omkhulu phakathi kwezingulube namadayi ukusetshenziswa kwazo.Odayi basetshenziselwa kakhulu izindwangu, kanti izingulube ikakhulukazi okungezona izindwangu.
Isizathu sokuthi kungani ama-pigments nama-dyes ahlukile kungenxa yokuthi ama-dyes ane-affinity, engase yaziwa nangokuthi ukuqondisa, ngoba izindwangu namadayi angakhangiswa futhi alungiswe ngama-molecule e-fiber;Ama-pigments awahlobene nazo zonke izinto ezinemibala, ikakhulukazi athembele kuma-resin, izinto ezinamathelayo, njll. ukuze afake imibala emikhiqizweni.Amadayi agcizelela obala futhi ngokuvamile anokukhanya okuhle;Ama-pigments agcizelela izici zokumboza futhi ngokuvamile abe nokuzinza okuhle.
Kunemehluko emithathu phakathi kwama-pigments namadayi:
Umehluko wokuqala phakathi kwama-pigments namadayi yi-Different Solubility.Umehluko oyinhloko phakathi kwezingulube namadayi ukuncibilika kwazo.Njengoba kwaziwa kahle, ama-pigments awancibiliki oketshezini, kuyilapho odayi bengancibilika ngokuqondile oketshezini olunjengamanzi, i-asidi, njalonjalo.
Umehluko wesibili phakathi kwama-pigments namadayi usezindleleni ezintathu Ezihlukene Zokubala.I-Pigment iwuketshezi olunombala oluyimpuphu oludinga ukuthululwa oketshezini ngaphambi kokufakwa umbala.Nakuba ingeke ibole futhi incibilike oketshezini, izohlakazwa ngokulinganayo.Ngemuva kokuhlanganisa ngokulinganayo, abasebenzisi bangaqala ukufaka imibala ngebhulashi.Indlela yokufaka imibala yamadayi iwukuba uwathululele oketshezini, ulinde ukuthi ancibilike ngokuphelele oketshezini, bese ufaka ibhulashi oketshezini lokudaya, bese ukhipha ibhulashi ukuze uxube ngqo futhi usebenzise umbala.
Umehluko wokugcina phakathi kwama-pigment namadayi ukusetshenziswa okuhlukene.Ngemva kokufunda le mehluko emibili engenhla, ake sibheke umehluko wokugcina, okuyisicelo.Ama-pigment asetshenziswa kakhulu ezingubo zokugqoka, iziyinki, ukuphrinta nokudaya, njll;Ngakolunye uhlangothi, odayi bavame ukusetshenziswa ezintweni zefiber, ubunjiniyela bamakhemikhali, noma ukuhlobisa izakhiwo.
Amakhasimende angakhetha i-pigment noma odayi ncamashi lapho ethenga.
