sarufa nhema, inozivikanwawo se ethyl sulfur pyrimidine, ndeye organic synthetic dhayi inonyanya kushandiswa mukudhaya, pigment uye inki maindasitiri.Muindasitiri yemachira, sulfur dema ndiyo dhayi huru yekudhaya cellulose fiber, iyo inonyanya kukodzera zvigadzirwa zvakasviba zvemachira ekotoni, pakati pawo.
Liquid Sulfur BlackuyeSulfur Blue 7ndiwo akanyanya kuwanda.Nzira yekudhayira yedhayi yesarufa ndeye: kutanga, dhayi resarufa inoderedzwa uye yakanyungudutswa mumushonga wedhayi, uye dhayi yedhayi inoumbwa inoshambadzirwa ne cellulose fibers, uye zvino inobatwa nemhepo oxidation kuita kuti cellulose fibers iratidze ruvara runodiwa.
Sulfur black dyeing inoda sodium sulfide sechinhu chinoderedza kunyungudutsa dhayi.Madhayi eSulfide pachawo haana kunyungudika mumvura, uye kana alkaline inoderedza dhayi inoshandiswa, dhayi inogona kuderedzwa kuita leucochromes uye yakanyungudika mumvura, uye iyo yakaumbwa leucochromic sodium munyu inogona kushambadzwa nefiber.Muchiitiko chaicho chekushanda, kudzikisa uye kupera kwemavara e sulfide kunoda kuitwa zvizere, uye chiyero chekuwedzera chinofanira kunonoka uye chakafanana.Mushure mekuwedzera dhayi, bika uye dhayi kwemaminetsi gumi, uye zvishoma nezvishoma uye zvakaenzana woisa munyu kukurudzira kudhaya.Iva nechokwadi chekuchenesa zvakakwana mushure mekudhaya kudzivirira dhayi yakasara kubva pakukanganisa maitiro ekudhaya.Mukuwedzera, mushure mekudhaya, usangoerekana watonhora kudzivirira "shiri paw prints".Panguva imwecheteyo, kurapwa kwe-anti-brittleness kunoda kushandiswa kwezvinyoro panguva yekudhaya.
Uye zvakare, sarufa dema inogona zvakare kushandiswa kugadzira pigment, nekuda kwekunaka kwayo kwechiedza uye kusagadzikana kwemamiriro ekunze, saka inoshandiswa zvakanyanya muindasitiri ye pigment.Mukugadzira inki, kushandiswa kwesarufa nhema zvakare yakafara kwazvo, senge inki uye kudhinda inki, ruvara rwayo rwakadzika, inogona kupa yakanaka kudhinda mhedzisiro, uye ine kushomeka kwemvura, kusapfeka uye kusagadzikana kwemakemikari.
