Abstract
Official abstract text for this publication.
A method for producing a printed textile item, the method including applying a treatment liquid containing an aggregating agent to a fabric using an inkjet method, applying a white ink having a charge density of at least 30 μeq/g, using a step of using an inkjet method and a wet-on-wet method, to the fabric to which the treatment liquid has been applied, applying a color ink for which the Young's modulus of the dried coating film is not more than 3.0 MPa, using an inkjet method and a wet-on-wet method, to the fabric to which the white ink has been applied.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for producing a printed textile item, the method comprising: applying a treatment liquid comprising an aggregating agent to a fabric by an inkjet method, applying a white ink having a charge density in a range of at least 30 μeq/g, by an inkjet method and a wet-on-wet method, to the fabric to which the treatment liquid has been applied, and applying a color ink for which a Young's modulus of a dried coating film is not more than 0.88 MPa, by an inkjet method and a wet-on-wet method, to the fabric to which the white ink has been applied. 2. The method for producing a printed textile item according to claim 1 , wherein the color ink comprises a pigment and a water-dispersible resin, and a mass ratio of the water-dispersible resin relative to the pigment (water-dispersible resin/pigment) is within a range from 2.5 to 5.0. 3. The method for producing a printed textile item according to claim 1 , wherein the color ink comprises a crosslinking agent. 4. The method for producing a printed textile item according to claim 2 , wherein the color ink comprises a crosslinking agent. 5. The method for producing a printed textile item according to claim 1 , wherein the white ink comprises: a water-dispersible resin A having a charge density in a range of not more than 55 μeq/g, and a water-dispersible resin B having a charge density in a range of 75 μeq/g or higher. 6. The method for producing a printed textile item according to claim 2 , wherein the white ink comprises: a water-dispersible resin A having a charge density in a range of not more than 55 μeq/g, and a water-dispersible resin B having a charge density in a range of 75 μeq/g or higher. 7. The method for producing a printed textile item according to claim 3 , wherein the white ink comprises: a water-dispersible resin A having a charge density in a range of not more than 55 μeq/g, and a water-dispersible resin B having a charge density in a range of 75 μeq/g or higher.
