Odayi besibabuleama-molecule e-heterocyclic ayinkimbinkimbi noma izingxube ezakhiwe ngokuncibilika noma ukubilisa izinhlanganisela eziphilayo eziqukethe ama-amino noma amaqembu e-nitro ane-Na-polysulphide ne-Sulfur.Odayi besulfure babizwa kanjalo njengoba bonke bequkethe ukuxhumana kweSulfur ngaphakathi kwama-molecule awo.

Odayi besulfure banemibala eminingi, inhlanganisela engancibiliki emanzini futhi kufanele baguqulwe babe amafomu ancibilikayo emanzini (ama-lucoform) ngaphambi kokuba afakwe ezintweni zendwangu.Lokhu kuguqulwa kwenziwa ukwelashwa okune-ejenti yokunciphisa njenge-dilute aqueous Na2S.Njengoba le lucoform kadayi weSulfur ibalulekile ezintweni ze-cellulosic.Zimuncwe ku-fiber surface.Bese bebuyiselwa udayi wokuqala ongancibiliki emanzini nge-oxidation.Lokhu kufakwa kwe-oxidation kwenziwa “ngomoya” (ukuchayeka emoyeni) noma ngokusebenzisa i-oxidizing ejenti efana ne-Na-dichromate (Na2Cr2O7).

Ama-ejenti anciphisayo aguqula u-“S” kudayi abe yiqembu elithi –SH kanye nokuxhumana kwesibabule.Khona-ke ngaphakathi kwempahla ama-thiols aqukethe amaqembu e-SH afakwa i-oxidized futhi ngaleyo ndlela aguqulelwe esimweni sokuqala sikadayi.

Lokhu kuboniswa ngezansi:

Idayi-SS-Dye + 2[H] = Idayi-SH + HS-Dye

Udayi-SH + HS-Dye +[O] = Idayi-SS-Dye + H₂O

Isibabule sinikeza umphumela omuhle kakhulu (Ithoni Ekhanyayo) lapho sisetshenziselwa ukukhiqiza amathunzi amnyama, Amnyama & ansundu kodwa amathunzi abomvu awanakutholwa odayi Besibabule.
 
Umlando we-Sulfur dyes ungafingqwa kanje ngezansi:

1. Odayi bokuqala beSulfur lapho benziwa khona ngo-1873 bashisisa babona uthuli, i-caustic soda neSulfur.Kwenzeka ngenhlanhla lapho umkhumbi wokusabela oqukethe i-Na2S uvuza futhi uthuli lwamasaha lusetshenziselwa ukusula isisombululo esiphumayo.Kamuva indwangu kakotini ihlangana nale sawdust engcolile bese iba namabala.

2. Ingqalabutho yangempela yodayi beSulfur yayiyi-vidal ekhiqiza i-vidal black (Igama ledayi Yesulphur) ngokuhlanganisa i-para-phenylene diamine ne-Na2S & Sulfur ngo-1893.

3. Ngo-1897 uKalischer wakhiqiza i-Immedial Black FF ngokushisa i-2, 4-dinitro-4-dihydroxy diphenylamine ne-Na-poly sulphide.

4. Ngo-1896 i-Read Holliday yethula izinhlobonhlobo zodayi abampunga, abansundu nabamnyama beSulfur ngokwenza kweSulphur, ama-alkali sulfide kanye nezinhlanganisela eziningi eziphilayo.
