Ukudaywa kweejini kwamkela ubukhulu becala ukudaya kwedayi ye-indigo, ukudaya kwesulfure kunye nokudaya okusebenzayo. Phakathi kwabo, ukudaya kwe-indigo yeyona ndlela yokudaya ilaphu ledenim yemveli, eyahlulahlulwe yaba yidayi yendalo ye-indigo kunye nedayi ye-indigo yokwenziwa. Idayi ye-indigo yendalo ikhutshwa kwingca ye-indigo kunye nezinye izityalo, ngelixa idayi ye-indigo yokwenziwa yenziwe kwiimveliso zepetrochemical ezifana ne-aniline kunye nezinye izinto eziluhlaza.
Ukongeza kwi-indigo yokudaya, ukudaya isulfure yenye yeendlela eziqhelekileyo zokudaya i-jeans. Le ndlela yokudaya isebenzisa i-vulcanized dayi ukudaya ilaphu elimnyama, elineempawu zokuhlambeka nokunganxibi. Xa kuthelekiswa nokudaya kwedayi ye-indigo, umbala we-sulfure wokudaya umbala ucace ngakumbi, ufanelekile ukuveliswa kwemibala eyahlukeneyo yee jeans.
Idayi evulcanized, ikakhulu esetyenziselwa ukudaya ifayibha yomqhaphu, ingasetyenziselwa amalaphu adityanisiweyo womqhaphu/ivithamin. Idayi zesulfure azinamaqela anyibilikayo emanzini kwisakhiwo sawo semolekyuli, ngoko ke azinakunyibilika ngokuthe ngqo emanzini. Nangona kunjalo, xa i-agent yokunciphisa njengesulfure ye-alkali yongezwa, i-disulphur bond, iqela le-sulfoxyl, kunye neqela le-quinone kwidayi yesulfure iyancitshiswa kwiqela le-sulfhydryl, oko kukuthi, i-leucosome, kwaye idayi inokunyibilika emanzini ngeli xesha.
Iingenelo eziphambili zedayi ezivuthwe zibandakanya ixabiso eliphantsi, kwaye idayi ngokubanzi iyahlambeka kwaye iyakhawuleza. Ukongeza, ukusetyenziswa kwedayi evuthweyo nayo ilula, kuphela emva kokuba idayi ichithwe inodaywa. Nangona kunjalo, umbala wemibala yeedayi zesulfure awugqibekanga, umbala awukhanyisi ngokwaneleyo, ikakhulukazi umnyama, omdaka, ohlaza okwesibhakabhaka njalo njalo. Nangona umbala okhawulezayo wokuhlamba uphezulu, ukukhawuleza kwi-bleaching kuphantsi, kwaye kulula ukuba brittle ngexesha lokugcinwa.
Inkampani yethu ivelisa ikakhuluSulphur Black 240%, ulwelo Sulphur emnyama, Sulfur Blue 7.Ukuthunyelwa ngokusisigxina eBangladesh. Indiya. Phakistan. IYiputa, kunye ne-Iran. Zombini unikezelo kunye nomgangatho uzinzile ngokukodwa. Okubaluleke ngakumbi inzuzo yexabiso.
