Kudhaya majini kunonyanya kushandisa kudhaya dhayi ye indigo, kudhaya dhayi yesulfure uye kudhaya dhayi inochinja-chinja. Pakati pazvo, kudhaya indigo ndiyo nzira yechinyakare yekudhaya jira re denim, yakakamurwa kuita dhayi yechisikigo ye indigo uye dhayi ye indigo yakagadzirwa. Dhayi yechisikigo ye indigo inotorwa kubva muuswa hwe indigo nedzimwe zvirimwa, nepo dhayi ye indigo yakagadzirwa kubva muzvigadzirwa zve petrochemical zvakaita se aniline nezvimwe zvinhu.
Pamusoro pekudhaya dhayi ye indigo, kudhaya sulphur ndeimwe yenzira dzakajairika dzekudhaya majini. Nzira iyi yekudhaya inoshandisa madhayi akasanganiswa ne vulcanized kudhaya jira rakasviba, iro rine hunhu hwekugezeka uye husingapfeki. Kana tichienzanisa nekudhaya dhayi ye indigo, ruvara rwekudhaya dhayi yesulphur rwakajeka, rwakakodzera kugadzirwa kwemavara akasiyana-siyana ejini.
Madhayi eVulcanized, anonyanya kushandiswa pakudhaya donje fiber, anogonawo kushandiswa pakugadzira machira akasanganiswa nedonje/mavhitamini. Madhayi esulfur haana mapoka anonyungudika mumvura muchimiro chawo chemamorekuru, saka haagone kunyungudika zvakananga mumvura. Zvisinei, kana chinhu chinoderedza mvura chakadai sealkali sulfur chikawedzerwa, disulphur bond, sulfoxyl group, uye quinone group musulfur dye zvinoderedzwa kuita sulfhydryl group, kureva, leucosome, uye dhayi inogona kunyungudika mumvura panguva ino.
Zvakanakira zvikuru zvemadhayi akasanganiswa zvinosanganisira mutengo wakaderera, uye dhayi inowanzo sukwa uye inokurumidza. Pamusoro pezvo, kushandiswa kwemadhayi akasanganiswa zvakareruka, chete kana dhayi yanyungudika kunogona kudhayiwa. Zvisinei, ruvara rwemadhayi esulfure haruna kukwana, ruvara haruna kupenya zvakakwana, kunyanya dema, brown, bhuruu nezvimwewo. Kunyangwe ruvara ruchikurumidza kusvika pakusuka rwakakwira, kukurumidza kusvika pakuchena kwakaderera, uye zviri nyore kuti rive rakapfava panguva yekuchengetera.
Kambani yedu inonyanya kugadziraSarufa Nhema 240%, mvura Sulphur nhema, Bhuruu reSulfur 7.Kutengeswa kwezvinhu kuBangladesh kwenguva refu. India. Pakistan. Egypt, neIran. Kuwanikwa kwezvinhu uye mhando yazvo zvakagadzikana zvikuru. Chinonyanya kukosha inyaya yemutengo.
