Ukusetshenziswa kwedayi ye-indigo kunomlando weminyaka engaphezu kuka-5000 futhi kubhekwa njengedayi endala kakhulu.Imboni yethu manje isebenzisa imishini ephakeme kakhulu kanye nobuchwepheshe bokukhiqiza ukukhiqiza i-indigo eluhlaza okwesibhakabhaka, ukuqinisekisa ukuthi imikhiqizo yethu ye-indigo blue iyikhwalithi engcono kakhulu. , futhi ukukhanya kombala kuhlangabezana nezidingo zezindinganiso zemboni yezingubo zamazwe ngamazwe kanye ne-jeans, ngombono wokufinyelela ezingeni lamazwe ngamazwe, ukwenza i-jeans ivelele kakhulu, nokwenza i-jeans imfashini ibe yinto ethandwa kakhulu.
(1) Indlela yokukhiqiza
I-Metal sodium ihlangana nosawoti we-potassium noketshezi lwe-caustic soda ukuze kukhiqizwe i-indoxyl, amanzi ahlangana nomoya ukuze kukhiqizwe i-indigo eluhlaza okwesibhakabhaka, bese iwasha ibe yikhekhe lesihlungi ngepuleti nohlaka, bese ilungisa udaka ngombhoshongo wokufutha ngezithako.
(2) Ukuncibilika
Incibilika kancane emanzini, i-ethanol, i-glycerin ne-propylene glycol, ayincibiliki emafutheni nasemafutheni.Isixazululo se-aqueous esingu-0.05% sasiluhlaza okwesibhakabhaka okumnyama.I-1g iyancibilika cishe ku-100ml, amanzi ku-25 ° C, ukuncibilika emanzini kuphansi kunezinye izingulube zokwenziwa ezidliwayo, kanti isixazululo samanzi esingu-0.05% siluhlaza okwesibhakabhaka.Incibilika ku-glycerin, i-propylene glycol, inyibilika kancane ku-ethanol, ayincibiliki emafutheni.Uma i-sulfuric acid egxilile, iluhlaza okwesibhakabhaka, futhi ngemva kokuhlanjululwa, iluhlaza okwesibhakabhaka.Isixazululo saso esinamanzi kanye ne-sodium hydroxide siluhlaza kuya kokuluhlaza okotshani.I-Indigo kulula ukuyifaka umbala, inethoni yombala ehlukile, futhi isetshenziswa kabanzi.Ukumelana nokushisa, ukumelana nokukhanya, ukumelana ne-alkali, ukumelana ne-oxidation, ukubekezelela usawoti kanye nokumelana namagciwane kokubili kumpofu.Iyafiphala lapho inciphisa, njengokunciphisa nge-sodium sulfoxylate noma i-glucose, iba mhlophe.Ubude begagasi bokumunca obukhulu ngu-610 nm ± 2 nm.
(3) Isicelo
Isetshenziswa kakhulu ukudaya ifayibha kakotini .Izingubo ze-pop "cowboy" ngokuvamile zenziwa ngentambo eluhlaza okwesibhakabhaka eshonayo e-indigo kanye nentambo emhlophe eyalukayo; , zisetshenziswa kahle endabeni yokubala imibala yokudla, i-biochemistry njll.
