Izici & Izinzuzo
- Inomphumela wokuhlakaza nowokuncibilikisa odayi.Ithuthukisa indawo yokulinganisa yamadayi.Ingasetshenziswa njenge-colloid evikelayo ohlelweni lokudaya.
- Izinzile ezingeni lokushisa eliphezulu, i-asidi, i-alkali, i-electrolyte namanzi aqinile.
- Akuthinti umthunzi wombala wezindwangu.
- Incibilika kalula emanzini.Igwebu eliphansi.
- Kulula ukuyisebenzisa.

Exhaust dyeing
Izindlela zokupheka zokudaya i-exhaust, okufaka phakathi izinto ezisizayo kanye nodayi, ngokwesiko zenziwe ngephesenti lesisindo uma kuqhathaniswa nesisindo se-substrate edaywayo.Izinto ezisizayo zingeniswa kuqala kubhavu wokudaya futhi zivunyelwe ukuba zijikeleze ukuze zivumele ukugxiliswa okufanayo kulo lonke udaka kanye nendawo engaphansi.Odayi babe sebengeniswa ku-dyebath futhi baphinde bavunyelwe ukuba bajikeleze ngaphambi kokuba izinga lokushisa likhushulwe ukuze kutholwe ukugxiliswa okufanayo kulo lonke udayi.Ukuthola ukugxiliswa okufanayo kwakho kokubili abasizi nodayi kubaluleke kakhulu njengoba ukugxila okungewona umfaniswano endaweni engaphansi kungaholela ekuthathweni kodayi okungalingani.Isivinini sokuthatha udayi (ukuphela) kodayi ngabanye kungahluka futhi kuzoncika kumakhemikhali abo kanye nezakhiwo ezibonakalayo kanye nohlobo nokwakhiwa kwe-substrate edaywayo.Izinga lokudaya libuye lincike ekugxilweni kukadayi, isilinganiso sotshwala, izinga lokushisa le-dyebath kanye nomthelela wezinto ezisizayo zokudaya.Amazinga okuphelelwa amandla ngokushesha aholela ekungalinganini kokusatshalaliswa kukadayi phezu kwendawo engaphansi, ngakho odayi kufanele bakhethwe ngokucophelela lapho besetshenziswa ekuphekeni kodayi abaningi;abakhiqizi abaningi bedayi bakhiqiza ulwazi olushoyo ukuthi yimaphi amadayi avela ebangeni lawo ahambisanayo ukuze afinyelele izinga lokunqwabelana kodayi ngesikhathi sokudaywa.Abadayi bafisa ukuthola ukukhathala okuphezulu ngangokunokwenzeka ukuze banciphise udayi osele emanzini angcolile futhi bakhulise inqwaba ukuze baphinde baphinde bakhiqize, kuyilapho besathola umthunzi odingwa ikhasimende.Inqubo yokudaya ekugcineni izophela ngokulingana, lapho ukugxila kukadayi ku-fiber kanye nendawo yokudaya kungashintshi kakhulu.Kucatshangwa ukuthi udayi ofakwe endaweni engaphansi ususabalele kuyo yonke ingxenye engaphansi okuholela emthunzini ofanayo odingwa ikhasimende nokuthi kusele inani elincane kuphela likadayi endaweni yokudaya.Yilapho umthunzi wokugcina we-substrate uhlolwa khona ngokumelene nendinganiso.Uma kukhona ukuphambuka emthunzini odingekayo, izengezo ezincane zedayi zingenziwa ku-dyebath ukuze kuzuzwe umthunzi odingekayo.
Ama-Dyers afisa ukufeza umthunzi ofanele okokuqala ngqá ukudaya ukuze kuncishiswe ukucubungula okwengeziwe nokunciphisa izindleko.Ukuze wenze lokhu, kudingeka amazinga okudaya afanayo kanye nezinga eliphezulu lokukhathala kodayi.Ukuze kuzuzwe imijikelezo emifushane yokudaya, ngaleyo ndlela kukhuliswe ukukhiqizwa, imishini eminingi yokudaya yesimanje ivaliwe ukuze kuqinisekiswe ukuthi i-dyebath igcinwa ezingeni lokushisa elidingekayo nokuthi akukho ukuhlukahluka kwezinga lokushisa ngaphakathi kwendawo yokudaya.Eminye imishini yokudaya ingacindezelwa ukuze utshwala obudayi bufudumale bufike ku-130°C okuvumela ama-substrates, njenge-polyester, ukuthi adaywe ngaphandle kwemfuneko yabathwali.
Kunezinhlobo ezimbili zemishini etholakalayo yokudaya i-exhaust: imishini ejikelezayo lapho i-substrate imile futhi utshwala obudayi busakazwa, nemishini yezimpahla ezijikelezayo lapho i-substrate notshwala obudayi kusakazwa khona.
