Ukusetyenziswa kwe #sodiumsulfite

1. I-arhente yokunciphisa i-bleaching,

2. Kwishishini lokuprinta kunye ne-#dyeing, isetyenziswa njenge-deoxidizer kunye ne-ejenti yokuxutywa kwe-bleaching yokukhuhla amalaphu e-cotton ahlukeneyo. Inokuthintela i-oxidation yendawo ye-cotton fibers kwaye ichaphazele amandla e-fiber, kunye nokuphucula ubumhlophe bemveliso yokucoca.

Ngaphambili: Igaqa le #rongalite lenziwa ngokusebenzisa #sodiummetabisulfite, #zincpowder, kunye ne-formaldehyde njengezinto ezisetyenziswayo ukwenza ukusabela kwe-redox emanzini.

Okulandelayo: Amanye amacebiso amancinci olawulo lwexesha :
