Method for producing printed textile item

Abstract

Disclosed is a method for producing a printed textile item including: applying a pretreatment liquid to a fabric, and applying a white ink using an inkjet method to the fabric to which the pretreatment liquid has been applied, wherein the pretreatment liquid contains a polyvalent metal salt, a surfactant, and water, and the white ink contains a white inorganic pigment, resin particles, a surfactant, and water.

What is claimed is: 
     
         1 . A method for producing a printed textile item comprising:
 applying a pretreatment liquid to a fabric, and   applying a white ink using an inkjet method to the fabric to which the pretreatment liquid has been applied, wherein   the pretreatment liquid contains a polyvalent metal salt, a surfactant, and water,   the white ink contains a white inorganic pigment, resin particles, a surfactant, and water,   an amount of the white pigment, relative to a total mass of the white ink, is within a range from 5.0 to 15.0% by mass,   a total amount of the white inorganic pigment and the resin particles, relative to the total mass of the white ink, is within a range from 20 to 35% by mass, and   an amount A (g/m 2 ) of the resin particles of the white ink applied to the fabric and an amount B (g/m 2 ) of the polyvalent metal salt of the pretreatment liquid applied to the fabric satisfy a relationship of A 2 /B≥50.   
     
     
         2 . The method for producing a printed textile item according to  claim 1 , wherein, in the white ink, a mass ratio of the resin particles relative to the white inorganic pigment is 2.5 or more. 
     
     
         3 . The method for producing a printed textile item according to  claim 1 , wherein the white ink contains a polyester-based polyurethane resin in the resin particles. 
     
     
         4 . The method for producing a printed textile item according to  claim 1 , wherein the white ink contains a polyester-based polyurethane resin in an amount of 50% by mass or more relative to the total mass of the resin particles. 
     
     
         5 . The method for producing a printed textile item according to  claim 1 , wherein the amount A (g/m 2 ) of the resin particles of the white ink applied to the fabric and the amount B (g/m 2 ) of the polyvalent metal salt of the pretreatment liquid applied to the fabric satisfy a relationship of A 2 /B≥80. 
     
     
         6 . The method for producing a printed textile item according to  claim 1 , wherein the amount A (g/m 2 ) of the resin particles of the white ink applied to the fabric and the amount B (g/m 2 ) of the polyvalent metal salt of the pretreatment liquid applied to the fabric satisfy a relationship of A 2 /B≥100.
