Sulfur black, inozivikanwawo se ethyl sulphur pyrimidine, idhayi rekugadzira zvinhu zvakasikwa rinoshandiswa zvakanyanya mumaindasitiri ekudhaya, pigment uye inki. Muindasitiri yemachira, sulphur black ndiyo dhayi huru yekudhaya fibers dze cellulose, iyo inonyanya kukodzera zvigadzirwa zvemachira edonje, pakati pazvo
Mvura Sulfur NhemauyeBhuruu reSulfur 7ndiwo anonyanya kuwanikwa. Maitiro ekudhaya dhayi resarufa ndeekuti: kutanga, dhayi resarufa rinoderedzwa ronyungudutswa kuita dhayi, uye maburi ekudhaya anoumbwa anonyungudutswa nefibers dzecellulose, uye ozogadziriswa nemhepo kuti fibers dzecellulose dziratidze ruvara rwunodiwa.
Kudhaya dhayi resarufa dema kunoda sodium sulfide sechinhu chinodzikisa dhayi kuti inyungudise dhayi. Madhayi esulfide pachawo haanyungudike mumvura, uye kana ma alkaline reduction agents ashandiswa, madhayi anogona kuderedzwa kuita leucochromes onyungudika mumvura, uye leucochromic sodium salts yakagadzirwa inogona kunyungudika nefibers. Mukushanda chaiko, maitiro ekuderedza nekunyungudika kwe sulfide dyes anofanira kuitwa zvizere, uye mwero wekuwedzera unofanira kunonoka uye wakaenzana. Mushure mekuwedzera dhayi, bika wodhaya kwemaminitsi gumi, wobva wawedzera munyu zvishoma nezvishoma kuti uwedzere kudhaya. Iva nechokwadi chekuchenesa zvakakwana mushure mekudhaya kudzivirira dhayi rakasara kuti risakanganise mhedzisiro yekudhaya. Pamusoro pezvo, mushure mekudhaya, usangoerekana watonhorera kudzivirira "kudhindwa kwemakumbo eshiri". Panguva imwe chete, kurapwa kwekudzivirira kupwanyika kunoda kushandiswa kwezvinyorovesa panguva yekudhaya.
Pamusoro pezvo, dema resulfure rinogonawo kushandiswa kugadzira pigments, nekuda kwekudzivirira kwayo chiedza uye kuramba mamiriro ekunze, saka rinoshandiswa zvakanyanya muindasitiri yepigments. Mukugadzira inki, kushandiswa kwedema resulfure kwakafarawo, senge inki yeinki nekudhinda, ruvara rwayo rwakadzama, runogona kupa mhedzisiro yakanaka yekudhinda, uye runodzivirira mvura, runodzivirira kupera uye runodzivirira makemikari.
