He hui organik ka Dye, pinepine i ke alo o nā kūlana wai e hoʻopau i ka hopena kemika, no laila ua kūʻai mua ʻia ka dye synthetic mua o ka honua i ke ʻano wai, ʻoiaʻiʻo, ʻo ke ʻano o ka dye mua me ka lakio o kēia manawa ua mamao loa, hiki ke manaʻo ʻia ʻo ia ke ʻano mua o ka dye wai i kēia lā. I kēlā manawa, ma kahi o 20% o nā waiwai he wai, a ʻo kēia mau dye wai he mau dye VAT a me nā dye mordant.

I ka makahiki 1923, ua hoʻohui mua ka poʻe Pelekane i nā mea hoʻohui i koho ʻia i ka dye mua a ma hope o ka wili ʻana, ua hana ʻia ka dye disperse aqueous dispersion insoluble. I ka makahiki 1910, ua wehe ʻia ka hapa nui o nā dyes a ua hana ʻia i loko o nā pauka maikaʻi o kahi nui.

Wahi a nā palapala 1924, i kēlā manawa ma kahi o 80% o ka hana ʻana o ka dye i ka pauka maikaʻi, ua hana ʻia nā dye VAT i loko o kahi ākea o ka hoʻolaha ʻana o ka nui o nā ʻāpana, mai ka maikaʻi loa a hiki i ka pauka 50um. Akā, ʻo ka pauka mua he mau hemahema o ka lepo koʻikoʻi a me ka palupalu haʻahaʻa.

Ma hope o 1930, ua hoʻomohala hou ʻia nā ʻano dyes dispersion, akā aia nō kekahi mau hemahema e like me ka maʻalahi o ka ua a me ka paʻa ʻole o ka mālama ʻana.

I kēia manawa, ua hoʻomaikaʻi nui ʻia ke ʻano hana hoʻoheheʻe wai o nā waiwai like ʻole ma hope o ka hoʻomaikaʻi ʻana i ke ʻano hana, hiki i ka manawa mālama ke hiki aku ma mua o ka hapalua makahiki me ka ʻole o ka hōʻino ʻana, ua haʻahaʻa ke kumukūʻai hana hoʻoheheʻe wai, maʻalahi e hoʻohana a ua hoʻomohala mau ʻia.

Mai ka makahiki 1950, ua hoʻolaha ka puka ʻana mai o ka mīkini one i ka hoʻomohala ʻana o ka ʻenehana ma hope o ka mālama ʻana. Hiki i ka wili pulu me ka mīkini one ke loaʻa nā ʻāpana ʻoi aku ka maikaʻi a me ka haiki. Eia kekahi, ua hoʻomaikaʻi ʻia ke ʻano hana i hiki i nā ʻāpana kumu o ka dye ke hiki i kahi 1um, a ua hoʻomaikaʻi nui ʻia ke ʻano o nā huahana i hana ʻia e ke kaʻina hana hou a me nā lako, a ua holomua nui ka hana ʻana o nā dye hiki ʻole ke hoʻoheheʻe ʻia.

Me ka holomua o nā mīkini kemika a me nā lako kemika, ua hoʻomaka ka ʻike ʻia ʻana o nā dyes granular. ʻO ka granularity o ka dye granular he 100 ~ 300 um, he mau ʻāpana hakahaka a he mau ʻāpana paʻa hoʻi, ʻoi aku ka maikaʻi o ka wai ma mua o ka pauka dye, ka wettability, ka hoʻopuehu ʻana, a lanakila pū kekahi i ka drawback o ka pauka dye lepo lana i ka lewa, ua ʻike koke ʻia nā ʻano dosage i hoʻokipa ʻia e ka ʻoihana hana a me ka noi, i kēia manawa ua hana ʻia nā dyes he nui i nā huahana granular.
