Sulfur dyestau muaj nyob rau ntau tshaj ib puas xyoo.Thawj cov tshuaj zawv plaub hau yog tsim los ntawm Croissant thiab Bretonniere hauv xyoo 1873. Lawv tau siv cov ntaub ntawv uas muaj cov organic fibers, xws li ntoo chips, humus, bran, khib nyiab paj rwb, thiab cov ntaub ntawv pov tseg thiab lwm yam, tau los ntawm cua sov alkali sulfide thiab polysulfide alkali.Cov xim tsaus nti thiab qias neeg hygroscopic dye muaj qhov tsis sib haum xeeb hauv cov da dej alkali thiab yooj yim soluble hauv dej.Thaum paj rwb yog dyed nyob rau hauv ib da dej alkali thiab ib tug sulfur da dej, ntsuab dyes yuav tau.Thaum raug huab cua los yog tshuaj oxidized nrog dichromate tov rau xim fixation, paj rwb ntaub tuaj yeem tig xim av.Vim tias cov dyes muaj cov khoom dyeing zoo thiab tus nqi qis, lawv tuaj yeem siv rau hauv kev lag luam paj rwb dyeing.
Xyoo 1893, R. Vikal melted p-aminophenol nrog sodium sulfide thiab sulfur los tsim sulfur dub dyes.Nws kuj pom tau tias eutectic ntawm qee yam benzene thiab naphthalene derivatives nrog sulfur thiab sodium sulfide tuaj yeem tsim ntau yam sulfur dub dyes.Txij thaum ntawd los, tib neeg tau tsim cov tshuaj zawv plaub hau xiav, Sulfur liab dyes thiab sulfur ntsuab dyes ntawm lub hauv paus no.Nyob rau tib lub sijhawm, txoj kev npaj thiab dyeing txheej txheem kuj tau zoo heev.Cov dej-soluble sulfur dyes, kua sulfur dyes thiab ib puag ncig tus phooj ywg sulfur dyes tau tshwm sim ib qho tom qab, ua cov tshuaj sulfur dyes tau tsim muaj zog.
Sulfur dyes yog ib qho ntawm cov khoom siv dav siv ntau tshaj plaws.Raws li cov lus ceeb toom, lub ntiaj teb cov zis ntawm sulfur dyes mus txog ntau pua txhiab tons, thiab ntau yam tseem ceeb tshaj plaws yog sulfur dub.Cov zis ntawm sulfur dub tso nyiaj rau 75% -85% ntawm tag nrho cov zis ntawm sulfur dyes.Vim nws yooj yim synthesis, tsis tshua muaj nqi, zoo ceev ceev, thiab tsis-carcinogenicity, nws yog txaus siab los ntawm ntau yam printing thiab dyeing manufacturers.Nws yog dav siv nyob rau hauv dyeing ntawm paj rwb thiab lwm yam cellulose fibers, nrog dub thiab xiav series yog cov feem ntau lug siv.
