Daim ntawv thov ntawm indigo dye muaj keeb kwm ntawm ntau tshaj 5000 xyoo thiab suav hais tias yog cov laus tshaj plaws dye.Our Hoobkas tam sim no siv cov cuab yeej siv siab tshaj plaws thiab cov thev naus laus zis ntau lawm los tsim indigo xiav, kom ntseeg tau tias peb cov khoom siv xiav indigo yog qhov zoo tshaj plaws. , thiab lub teeb xim ua tau raws li qhov yuav tsum tau ua ntawm kev lag luam khaub ncaws thoob ntiaj teb thiab ris tsho hnav ris tsho, nrog rau kev pom mus txog qib thoob ntiaj teb, ua rau cov ris tsho hnav zoo tshaj plaws, thiab ua rau cov ris tsho hnav ris tsho yog qhov nrov dua.
(1) Txoj kev tsim khoom
Hlau sodium reacts nrog poov tshuaj ntsev thiab caustic soda kua los tsim indoxyl, dej reacts nrog huab cua los tsim indigo xiav, thiab ces ntxuav nws mus rau hauv lim ncuav mog qab zib los ntawm phaj thiab ncej, thiab ces granulates slurry los ntawm cov tshuaj tsuag ntauwd nrog additives.
(2) Solubility
Me ntsis soluble hauv dej, ethanol, glycerin thiab propylene glycol, insoluble hauv roj thiab rog.0.05% aqueous tov yog xiav tsaus.1g yog soluble nyob rau hauv li 100ml, dej ntawm 25 ° C, solubility nyob rau hauv dej yog qis dua lwm yam edible hluavtaws pigments, thiab 0.05% aqueous tov yog xiav.Soluble hauv glycerin, propylene glycol, me ntsis soluble hauv ethanol, insoluble hauv roj.Nyob rau hauv cov ntaub ntawv ntawm concentrated sulfuric acid, nws yog xiav tsaus, thiab tom qab dilution, nws yog xiav.Nws cov tshuaj aqueous ntxiv rau sodium hydroxide yog ntsuab rau yellowish ntsuab.Indigo yog ib qho yooj yim rau xim, muaj ib tug tshwj xeeb xim tone, thiab yog dav siv.Thaum tshav kub kub tsis kam, lub teeb tsis kam, alkali tsis kam, oxidation kuj, ntsev kam rau ua thiab cov kab mob tsis zoo yog ob qho tib si tsis zoo.Fading thaum txo, xws li txo nrog sodium sulfoxylate lossis qabzib, nws ua dawb.Qhov siab tshaj plaws nqus wavelength yog 610 nm ± 2 nm.
(3) Kev thov
Nws yog tsuas yog siv los zas paj rwb fiber ntau .Cov khaub ncaws pop "cowboy" feem ntau yog ua los ntawm indigo xiav tuag longitudinal yarn thiab dawb xov paj interweaving; Nws tuaj yeem siv nrog sulfurated coloring teeb meem; Tsis tas li ntawd peb tuaj yeem tau txais indigo dawb, bromized indigo xiav los ntawm nws. , lawv tau zoo siv hauv zaub mov xim teeb meem, biochemistry thiab lwm yam.
