ʻO ka hoʻohana ʻana i ka wai indigo he mōʻaukala ʻoi aku ma mua o 5000 mau makahiki a ua manaʻo ʻia ʻo ia ka mea kahiko loa. , a ua kūpono ke kukui kala i nā koi o ka lole o ka honua a me nā kūlana ʻoihana jeans, me ka manaʻo e hōʻea i ka pae honua, e hana i nā jeans i ʻoi aku ka maikaʻi, a me ka hana ʻana i ke ʻano jeans i mea kaulana loa.
(1) Hana hana
Hoʻopili ka sodium metala me ka paʻakai paʻakai a me ka wai hoʻoheheʻe caustic e hoʻohua i ka indoxyl, hana ka wai me ka ea e hoʻohua i ka ʻulaʻula indigo, a laila holoi ʻia i loko o ka kānana keke ma o ka pā a me ke kiʻi, a laila granulates i ka slurry ma o ka hale kiaʻi spray me nā mea hoʻohui.
(2) Solubility
Hiki ke hoʻoheheʻe ʻia i ka wai, ethanol, glycerin a me propylene glycol, hiki ʻole ke hoʻoheheʻe ʻia i ka ʻaila a me nā momona.He uliuli ʻeleʻele ka hoʻonā wai 0.05%.Hiki ke hoʻoheheʻe ʻia ka 1g ma kahi o 100ml, ka wai ma 25 ° C, ʻoi aku ka haʻahaʻa o ka solubility i ka wai ma mua o nā puaʻa synthetic edible, a ʻo ka 0.05% aqueous solution he uliuli.Hiki ke hoʻoheheʻe ʻia i ka glycerin, propylene glycol, hiki ke hoʻoheheʻe ʻia i ka ethanol, hiki ʻole ke hoʻoheheʻe ʻia i ka ʻaila.I ka hihia o ka sulfuric acid concentrated, he uliuli uliuli, a ma hope o ka dilution, he uliuli.He ʻōmaʻomaʻo a ʻōmaʻomaʻo melemele kona wai wai me ka sodium hydroxide.He maʻalahi ke kala ʻo Indigo, he leo kala like ʻole, a hoʻohana nui ʻia.ʻO ke kū'ē wela, ke kū'ē māmā, ke kū'ē alkali, ke kū'ē oxidation, ka paʻakai paʻakai a me ke kū'ē bacteria.ʻO ka maloʻo i ka wā e hoʻemi ai, e like me ka hoʻemi ʻana me ka sodium sulfoxylate a i ʻole ka glucose, lilo ia i keʻokeʻo.ʻO ka lōʻihi hawewe absorption he 610 nm ± 2 nm.
(3) Noi
Hoʻohana nui ʻia ia e kala i ka pulupulu pulupulu. ʻO ka pop "paniolo" lole ka hapa nui i hana ʻia e indigo blue dying longitudinal yarn a me keʻokeʻo wili interweaving; , hoʻohana maikaʻi ʻia lākou i ka mea ʻai meaʻai, biochemistry etc.
