On the Dyeing Properties of Cationic Modified Cotton with Reactive Ink

Studies of dyeing properties of cationic modified cotton with reactive ink are to seek a way of increasing the colour yields in the inkjet printing on cotton fabrics.The results show that the dye uptake and the fixation of reactive ink on the cationic modified cotton are increased,while the fast of surface friction is little decreased.During the dyeing,it is found that there is no obvious increase of dye uptake by adding salt into the dye bath and somewhat decrease is noticed in some case.
