The Resist/Discharge Behaviors of Addition Type Reactive Dye in Resist/Discharge Printing of Cotton Fabrics

The resist and discharge behaviors of an addition type reactive dye, C.I. Reactive Blue 19, with three resisting agents in resist or discharge printing of cotton fabrics were investigated by visible spectrophotometer, FT-lR and IH-NMR. Resisting agents used were formaldehyde sodium bisulfite(FASB) , benzaldehyde sodium bisulfite(BASB) and glyoxal sodium bisulfite(GSB). It was confirmed that the resisting agents reacted with the activated vinyl sulfone group of dye and formed inactive dye complexes prior to reacting with cellulose. Three resisting agents showed good resistibility and the order was BASB > GSB > FASB.
