Kushandiswa kwedhayi ye indigo ine nhoroondo yemakore anopfuura 5000 uye inonzi ndiyo yekare dhayi.Fekitari yedu ikozvino inoshandisa michina yepamusoro uye teknolojia yekugadzira kugadzira indigo blue, kuti tive nechokwadi chokuti zvigadzirwa zvedu zve indigo blue ndezvakanakisisa. , uye chiedza chemavara chinosangana nezvinodiwa zvemarudzi ose ezvipfeko uye jeans industry zviyero, nechinangwa chekusvika kune dzimwe nyika, kuita kuti jeans ive yakakurumbira, uye kuita jeans fashoni chinhu chinonyanya kufarirwa.
(1) Nzira yekugadzira
Metal sodium inopindirana ne potassium munyu uye caustic soda fluid kugadzira indoxyl, mvura inopindirana nemhepo kuti ibudise indigo yebhuruu, yobva yaigeza mufirita keke kuburikidza nendiro uye furemu, yobva yaita granulate slurry kuburikidza nespray tower ine additives.
(2) Kunyungudika
Zvishoma kunyungudika mumvura, ethanol, glycerin uye propylene glycol, isinganyunguriki mumafuta nemafuta.Iyo 0.05% aqueous solution yaive yakasviba yebhuruu.1g inonyungudika ingangoita 100ml, mvura iri pa25 ° C, kunyungudika mumvura kwakadzikira pane mamwe mavara ekugadzira anodyika, uye 0.05% aqueous solution iblue.Soluble mu glycerin, propylene glycol, zvishoma soluble mu ethanol, isinganyunguriki mumafuta.Kana iri concentrated sulfuric acid, yakasviba bhuruu, uye mushure mekudzikiswa, ibhuruu.Mushonga wayo une aqueous pamwe ne sodium hydroxide yakasvibira kusvika kune yegirini.Indigo iri nyore kuisa ruvara, ine yakasarudzika toni yemavara, uye inoshandiswa zvakanyanya.Kupisa kupisa, kusamira kwechiedza, alkali resistance, oxidation resistance, munyu kushivirira uye kuramba kwebhakitiriya zvose hazvina kunaka.Kupera kana kuderera, sekuderedza ne sodium sulfoxylate kana glucose, inova chena.Iyo yakanyanya kunyura wavelength ndeye 610 nm ± 2 nm.
(3) Kushandisa
Inonyanya kushandiswa kudhayira donje faibha .Mhembe dzepop "cowboy" dzinonyanya kugadzirwa neindigo yebhuruu inofa longitudinal shinda uye chena shinda yakarukwa;Inogona kushandiswa ne sulfurated coloring matter; Zvakare tinogona kuwana indigo chena,bromized indigo yebhuruu kubva mairi. , iwo anonyatso shandiswa mune chikafu coloring nyaya, biochemistry nezvimwe.
