Pre-treatment of cotton fabric by poly(propylene imine ) dendrimer enhanced its color strength using C.I DIRECT RED 81 and C.I. DIRECT BLUE 78. Application of this dendrimer and the direct dyes simultaneously on cotton fabric by exhaust as well as continuos dyeing method has been studied with slightly improved dyeing results. Pre-treatment of the cotton fabric with dendrimer in emulsion form using pad-dry method, followed by continuous dyeing, increased in color strength and level dyeing as well as light and wash fastness was achieved. The use of the dendrimer in emulsion form prevents the aggregation of dendrimer. As a result, level dyeing with C.I. DIRECT RED 81 and C.I. DIRECT BLUE 78 dyes as well as satisfactory color strength has been noticed.
