An inkjet printing fluid set for printing on textile, the fluid set comprising:
- a) an aqueous pretreatment composition comprising an ink-aggregating agent, wherein said ink-aggregating agent is one or more members selected from a cationic polymer, a multivalent metal salt, an organic acid, and mixtures thereof;
- and
- b) an aqueous inkjet ink comprising a colorant and a first polymeric binder, wherein the colorant is a mixture of a pigment and a disperse dye, and the first polymeric binder is one or more members selected from the group consisting of polyester polyol based waterborne polyurethane, polycarbonate polyol based waterborne polyurethane, polyester-carbonate polyol based waterborne polyurethane, acrylic emulsion polymer, styrene acrylic emulsion polymer, vinyl acetate-ethylene copolymer dispersion, and mixtures thereof.
A method of digital printing a textile fabric comprising:
- a) providing a textile substrate;
- b) applying a pretreatment composition comprising an ink-aggregating agent, wherein said ink-aggregating agent is one or more members selected from a cationic polymer, a multivalent metal salt, an organic acid and mixtures thereof;
- and
- c) jetting an aqueous inkjet ink onto the textile substrate;
- wherein said aqueous inkjet ink comprises a colorant and a first polymeric binder, and said colorant is a mixture of a pigment and a disperse dye.
