Basic Dyes
Dab tsi yog Basic Dyes
Basic dyes yog cov dej-soluble cationic dyes uas yog siv rau acrylic fibers, tab sis nrhiav tau ib co siv rau ntaub plaub thiab txhob lo lo ntxhuav. Feem ntau, acetic acid yog ntxiv rau cov dye da dej los pab txhawb nqa cov dye mus rau fiber ntau. Basic dyes kuj yog siv nyob rau hauv cov xim ntawm daim ntawv.Basic dyes yog hu ua li ntawd txij li thaum lawv yog ntsev ntawm organic bases. Lawv tseem hu ua cationic dyes vim tias muaj cov nqi zoo hauv cov xim molecules nyob rau hauv dyeing tej yam kev mob. Thaum lub sij hawm dyeing daim ntawv thov, qhov tsis zoo nqi acrylic fiber attracts qhov zoo nqi dye cations rau ionic bonding. Vim muaj kev nyiam siab ntawm qhov sib txawv ntawm cov khoom siv fiber ntau thiab cov dyeing molecules, muaj kev pheej hmoo ntawm kev dyeing tsis zoo vim tias muaj tus nqi siab ntawm dyeing. Qhov kev pheej hmoo no tuaj yeem raug txo los ntawm kev ceev faj ntawm dyeing kub thiab siv cov tshuaj tiv thaiv tsim nyog.

Hom Basic Dyes
Auramine O
Qhov tseem ceeb tshaj plaws ntawm cov xim daj yog auramine O, uas yog kev hwm rau cov xim ntshiab tshwj xeeb uas nws tsim. Nws yog tsim los ntawm cua sov 4,4'- dimethylaminodiphenylmethane, sulfur, ammonium chloride, thiab sodium chloride (raws li diluents) mus rau 175 degree nyob rau hauv lub xub ntiag ntawm gaseous ammonia. Qhov tshwm sim Auramine puag yog hloov mus rau Auramine O, uas yog nws cov hydrochloride.
Malachite Ntsuab
Malachite Green yog tsim los ntawm kev sib txuas ob lub dimethylaniline molecules nrog ib qho benzaldehyde molecule. Cov dye ntsev nrog cov kua qaub yog tom qab ntawd ua los ntawm oxidizing lub leuco puag nrog oxidizing cov neeg ua haujlwm nrog lub peev xwm electrochemical siab, xws li txhuas dioxide.
Methylene Xiav
Methylene Blue yog tsim los ntawm oxidising ib tug sib tov ntawm dimethylaniline thiab-amino-dimethyl aniline (nyob rau hauv sib npaug zos npaum li cas) thiab sodium thiosulphate nyob rau hauv lub xub ntiag ntawm zinc chloride nrog sodium dichromate thiab hydrochloric acid (kom tau txais qhov kawg dye li zinc chloride ob ntsev).
Tshiab Magenta

Los ntawm distilling nrog chav, lub unreacted o-toluidine thiab o-nitrotoluene raug tshem tawm, cov residue yog lim kub, thiab Fuchsin tshiab yog salted tawm.
Cov yam ntxwv tseem ceeb ntawm Basic Dyes tau piav qhia hauv qab no
Ionic xwm -Lub ionic xwm ntawm cov dyes yog cationic.
Shade range -Cov dyes no nthuav tawm qhov ntxoov ntxoo tsis txwv nrog lub zog tinctorial siab, ci ntsa iab thiab ntau xim muaj cov khoom fluorescent.
Solubility -Solubility ntawm cov dyes yog zoo heev nyob rau hauv dej, nyob rau hauv lub xub ntiag ntawm glacial acetic acid.
Leveling zog -Cov dyes no muaj kev tawm tsam siab heev, yog li kev ua haujlwm tsis zoo.
Kev qaug zog -Cationic dyes tso tawm ntawm tus nqi sib txawv, K qhov tseem ceeb yog siv los txheeb xyuas cov yam ntxwv ntawm cov cationic dyes. K=1 txhais tau tias kev qaug zog sai tshaj plaws, thaum K=5 txhais tau tias qeeb tshaj plaws. Yog li thaum ua qhov sib xyaw ntxoov ntxoo cov dyes ntawm cov txiaj ntsig K zoo sib xws yuav tsum tau siv.
Kev sib raug zoo -Cov dyes no qhia tau hais tias muaj kev sib raug zoo heev rau cov ntaub plaub, txhob lo lo ntxhuav thiab cationic dye tuaj yeem acrylic, tab sis tsis muaj affinity rau cellulosics. Txhawm rau dye cellulosics nrog cov xim yooj yim, cov khoom siv yuav tsum tau kho nrog cov tshuaj mordanting uas tsim nyog.
Cov nram qab no yog Cov Khoom Tseem Ceeb ntawm Basic Dyes
Ionic cim
Basic dyes yog cationic soluble ntsev ntawm cov xim xim nrog cov cim ionic. Cov dyestuff yog qhov yooj yim lossis zoo radical hauv cov xim yooj yim, uas yog ntsev, feem ntau yog chlorides.
Reactivity
Nyob rau sab tseem ceeb ntawm cov ntsiab lus isoelectric, cov dyes yooj yim teb. Cov no yog siv rau ntawm anionic substrates los tsim electrostatic attraction.
Cationic dyes
Vim hais tias cov chromophore hauv cov xim yooj yim molecules muaj cov nqi zoo, lawv raug hu ua cationic dyes.
Qhov ntxoov ntxoo
Cov dyes muaj qhov ntxoov ntxoo tsis kawg, muaj zog tinctorial zog, ci ntsa iab, thiab fluorescent zoo hauv ntau xim.
Solubility
Ntau cov xim yooj yim tsuas yog soluble hauv dej xwb, tab sis yooj yim soluble hauv cawv lossis methylated ntsuj plig. Qhov sib ntxiv ntawm glacial acetic acid pab kom sai sai ntawm cov xim yooj yim hauv dej.
Leveling khoom
Vim tias cov xim no muaj qhov sib txawv siab, lawv muaj cov khoom tsis zoo.
Kev qaug zog
Cationic dyes muaj qhov sib txawv ntawm kev qaug zog; K qhov tseem ceeb yog siv los txiav txim siab cationic dyes 's exhaustion yam ntxwv. Qhov nrawm tshaj plaws yog K=1, thaum lub zog qeeb tshaj plaws yog K=5. Yog li ntawd, dyes nrog cov txiaj ntsig K zoo ib yam yuav tsum tau siv los tsim cov xim sib xyaw ua ke.
Kev sib raug zoo
Cov dyes no muaj kev sib raug zoo rau cov ntaub plaub, txhob lo lo ntxhuav, thiab cationic dye-tau acrylic, tab sis tsis muaj affinity rau cellulosic. Txhawm rau siv cov xim yooj yim ntawm cellulosic, cov khoom siv yuav tsum huv.
Daim ntawv thov rau paj rwb ntaub
Cov xim yooj yim tsis ua haujlwm ntawm paj rwb vim tias cov qauv tsis yog qauv lossis loj txaus los muab cov khoom nplaum tsim nyog lossis kev sib raug zoo. Txawm li cas los xij, tom qab kho cov paj rwb lossis lwm yam textiles dyed nrog cov xim ncaj qha, cov dyestuffs yog siv. Cov dyestuff ncaj qha ua haujlwm raws li tus neeg mob hauv qhov no.
Cov yam ntxwv ceev ceev
Kev ntub dej nrawm yog qhov zoo, thaum lightfastness tsis zoo rau nruab nrab. Rov qab tanning tuaj yeem txhim kho qhov ntub nrawm ntawm cov xim yooj yim ntawm cov protein fibers. Qhov no yog ua tiav tom qab cov khoom siv xim tau raug kho nrog tannic acid kom tsim tau ib qho kev sib xyaw ua ke, uas txo cov peev xwm ntawm kev tsiv teb tsaws.
Yuav Ua Li Cas Xaiv Basic Dyes

05
Yuav Ua Li Cas Cov Dyes Yooj Yim Ua Haujlwm
Basic dyes muaj peev xwm sib txuas nrog cov ntawv fibers vim lawv cov nqi zoo. Cov ntawv fibers raug them tsis zoo, uas txhais tau hais tias lawv tau txais txiaj ntsig zoo rau cov khoom lag luam zoo xws li cov xim yooj yim.
Thaum cov dyes yooj yim ntxiv rau hauv dej, lawv yaj thiab dhau los ua cov cations zoo. Cov cations no tau ntxim nyiam rau qhov tsis zoo ntawm cov ntawv fibers, ua rau cov dyes sib txuas nrog cov fibers. Lub zog ntawm daim ntawv cog lus ntawm cov xim yooj yim thiab cov ntawv fibers nyob ntawm cov khoom ntawm cov xim thiab cov fibers.
Thaum cov xim yooj yim tau sib txuas nrog cov ntawv fibers, nws yuav embedded nyob rau hauv lub fiber matrix. Qhov no txhais tau hais tias cov xim yog resistant rau fading los yog khiav tshaj nws yuav yog hais tias cov dye tsuas yog txheej txheej ntawm daim ntawv.
Qhov txawv ntawm Acid Dyes thiab Basic Dyes yog dab tsi?
Cov khoom siv tshuaj
Acid dyes feem ntau muaj cov acidic pawg (xws li sulfonic acid pawg lossis carboxylic acid pawg) thiab yog anionic dyes uas dye hauv acidic media; Basic dyes muaj cov amino pawg thiab yog cationic dyes uas dye nyob rau hauv alkaline media. 1245678 ib
Daim ntawv thov Scope
Acid dyes yog siv rau dyeing wool, txhob lo lo ntxhuav thiab nylon, nrog rau tawv, ntawv, number case, thiab lwm yam; yooj yim dyes yog tsuas yog siv rau dyeing cell phab ntsa, cell nuclei thiab tej yam tshwj xeeb organelles, xws li mucus, collagen, actin, thiab lwm yam, thiab kuj yog siv nyob rau hauv cov xim ntawm cov ntawv sau thiab ntawv thiab zus tau tej cov pas dej.
Dyeing nyhuv
Dyeing fixatives yuav tsum tau ntxiv thaum dyeing nrog acid dyes, uas muaj cov xim ci thiab ua tiav chromatograms, tab sis tsis zoo lub teeb ceev; yooj yim dyes muaj cov xim ci thiab muaj zog fluorescence, tab sis kuj tsis muaj zog tinting zog, ceev dyeing speeds, thiab tsis tas yuav dyeing fixatives, tab sis lawv yog ib qho yooj yim mus use. ploj mus.
Environmental Impact
Acid dyes yog dyed nyob rau hauv ib puag ncig acidic, thiab acidic wastewater yuav raug tso tawm thaum lub sij hawm dyeing txheej txheem, uas muaj tej yam ua paug rau ib puag ncig; Cov dyes yooj yim yog dyed nyob rau hauv ib qho chaw alkaline, thiab cov dej khib nyiab tsim thaum lub sij hawm dyeing yog huv si thiab muaj kev cuam tshuam rau ib puag ncig.
Tej yam uas yuav tsum nco ntsoov txog Basic Dyes
Thaum siv alkaline dyes, koj yuav tsum tau xyuam xim rau cov teeb meem kev nyab xeeb. Koj yuav tsum ua raws li kev khaws cia thiab siv cov txheej txheem ntawm cov tshuaj reagents, thiab siv cov tshuaj reagents kom ntau li ntau tau.
Thaum lub sij hawm dyeing txheej txheem, dyeing tej yam kev mob yuav tsum tau nruj me ntsis tswj kom tsis txhob deviations uas yuav cuam tshuam rau dyeing nyhuv.
Tom qab dyeing tiav lawm, kev tu thiab ziab kom txaus yuav tsum tau ua kom muaj kev ruaj ntseg thiab ci ntsa iab ntawm dyeing.
