I-Sulphur Emnyama(CAS 1326-82-5) yeyona isetyenziswa kakhulu yiSulphur Dye In Textile kwijeans. Inika imibala emnyama enzulu kunye nokusebenza kakuhle kweendleko, nto leyo eyenza ukuba ibe lolona khetho luphezulu kwimveliso enkulu yejeans emnyama kunye nejeans kwishishini lonke. Nangona kunjalo, ukuqhekeka kwentambo kunye nelaphu emva kokudaywa yingxaki eqhelekileyo yomgangatho ebangela ukulahleka kwamandla, ukuqhekeka, kunye nokonakala komgubo ngexesha lokugcina.
Unobangela Wokubhitya KweDenim
Njengedayi yelaphu enesulfur eninzi, iSulphur Black ineebhondi ze-disulfide ezingazinzanga kunye ne-polysulfide. Phantsi kobushushu obuphezulu kunye nokufuma, iibhondi ze-polysulfide ezisebenzayo kwi-denim kwi-jeans ziyanyibilika emoyeni, zivelise ii-sulfur oxides ezisabela kunye nokufuma ukuze zivelise i-sulfuric acid. Le asidi itshabalalisa iifayibha ze-cotton cellulose, itshabalalisa kancinci kancinci isakhiwo selaphu kwaye ikhokelele ekubeni i-fragile ngokusisigxina.
Izisombululo Ezisebenzayo Zokulwa Nokuqhekeka Kweenwele
Okokuqala, lawula ngokungqongqo umthamo wedayi.I-Sulphur EmnyamaIshiya iintsalela zesalfure ezingaphendulwanga kwidenim emnyama, nto leyo enyusa umngcipheko we-oxidation kunye nokunciphisa ukukhawuleza kombala. Okwesibini, hlamba ngokucokisekileyo emva kokudaya ukuze ususe umbala odadayo kunye nokungcola okushiyekileyo, unqumle imithombo evelisa i-asidi.
Okwesithathu, sebenzisa unyango lobuchwephesha lokulwa nokuqhekeka kwe-urea, i-soda ash kunye ne-sodium acetate ukuze unciphise izinto ze-asidi kwaye uzinzise ulwakhiwo lweemolekyuli zedayi. Okwesine, sebenzisa unyango lwangaphambi kokubilisa ngamanzi acocekileyo kwintambo yedenim ukuze unciphise ukuqhekeka xa kuthelekiswa nonyango lwendabuko lwe-lye. Okwesihlanu, idenim edayiweyo eyomileyo kwijean ngexesha elifanelekileyo ukuze kuthintelwe ukuxinana okumanzi kunye nokunciphisa ixabiso le-pH.
Amanyathelo okukhusela kwimveliso ephambili
Ungaze upakishe idenim eshushu ngqo emva kokuba yomile; yipholise ngokwendalo ukuya kubushushu begumbi ukuthintela ukuqokelelana kobushushu ekukhawuleziseni ukubola kwedayi. Gcina iindawo zemveliso kunye neendawo zokugcina zomile kwaye zingena umoya ukuze kuthintelwe i-oxidation. Gcina idosi yedayi izinzile, amaxesha okuhlamba kunye nedosi eyongezelelweyo ukuqinisekisa umgangatho webhetshi ohambelanayo.
Kufuphi,I-Sulphur Emnyama(CAS 1326-82-5) ukubuthathaka kuyalawuleka. Ukulungiswa okusemgangathweni kusombulula ngempumelelo ukubuthathaka kweejini zedenim, kuzinzisa umgangatho wejini emnyama kushishino lokuvelisa iijini.
