Abstract

Pretreatment of cotton fabric with poly(propylene imine) dendrimer enhanced its colour strength using C.I. Direct Red 81 and C.I. Direct Blue 78. Application of this dendrimer and the direct dye simultaneously on cotton fabric by the exhaust and the continuous dyeing method were studied; slight improvements in the dyeing results were obtained. Pretreatment of the cotton fabric with dendrimer in an emulsion form using the pad-dry method followed by continuous dyeing markedly increased the color strength. In addition, level dyeing was obtained, and no negative effects on the fastness properties of the dyes used were observed
