Sulfur dhayimamorekuru akaomarara eheterocyclic kana misanganiswa inoumbwa nekunyungudusa kana kufashaidza organic komisheni ine amino kana nitro mapoka ane Na-polysulphide neSulfur.Madhayi eSulfur anodaidzwa kudaro sezvo ese ane Sulfur linkage mukati memamorekuru awo.

Dhayi dzesarufa dzine ruvara rwakanyanya, mvura isinganyunguriki uye inofanirwa kuchinjirwa kuita mafomu anonyungudika emvura (lucoforms) asati aiswa kune machira.Shanduko iyi inoitwa nemushonga une chinodzikisa senge dilute aqueous Na2S.Sezvo iyi lucoform yeSulfur dhayi yakakosha kune cellulosic zvinhu.Vanobatwa pane fiber pamusoro.Ipapo ivo vanodzoreredzwa yepakutanga mvura isinganyunguriki fomu yedhayi neoxidation.Iyi oxidation inoitwa ne "airing" (kuratidzwa kumhepo) kana nekushandisa oxidizing agent seNa-dichromate (Na2Cr2O7).

Iwo anodzikisa agent anoshandura "S" mudhayi mu -SH boka uye Sulfur linkages.Zvino mukati mezvinhu izvo thiols ine -SH mapoka anoiswa oxidized uye nekudaro anodzoserwa kune yekutanga fomu yedhayi.

Izvi zvinoratidzwa pazasi:

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

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

Sulfur inopa yakanakisa mhedzisiro (Bright Toni) kana ichishandiswa kugadzira dema, dema & shava mimvuri asi tsvuku mimvuri haigone kuwanikwa neSulfur dhayi.
 
Nhoroondo yedhayi dzeSulfur inogona kupfupikiswa sepazasi:

1. Dhayi dzeSulfur dzekutanga dzakagadzirwa muna 1873 kudziyisa dzakaona huruva, caustic soda neSulfur.Zvakaitika netsaona apo chikepe chemaitiro chine Na2S chaidonha uye guruva resaha rakashandiswa kupukuta mhinduro yaibuda.Gare gare jira redonje rinosangana nesawdust iyi ine tsvina uye inosvibiswa.

2. Iye piyona chaiye wedhayi dzeSulfur aive vidal anoburitsa vidal black (Zita reSulfur dhayi) nekusanganisa para-phenylene diamine neNa2S & Sulfur muna 1893.

3. Muna 1897 Kalischer yakabudisa Immedial Black FF nekupisa 2, 4-dinitro-4-dihydroxy diphenylamine neNa-poly sulphide.

4. Muna 1896 Read Holliday yakaunza huwandu hwegrey, brown uye dema Sulfur dhayi nekuita kweSulfur, alkali sulphides uye akawanda organic compounds.
