Abstract

A pretreatment liquid for ink jet textile printing according to an aspect of the invention used by being applied to a fabric before applying an ink composition for ink jet textile printing to the fabric includes a multivalent metal salt; and an aqueous medium, in which the concentration of the multivalent metal salt is within in a range of 0.025 mol/kg or more and 0.08 mol/kg or less. A textile printing method according to another aspect the invention includes applying a pretreatment liquid to at least a partial region of a fabric; and applying an ink composition for ink jet textile printing to at least a portion of the region to which the pretreatment liquid is applied.

First claim

What is claimed is:

1. A pretreatment liquid for ink jet textile printing used by being applied to a fabric before applying an ink composition for ink jet textile printing to the fabric, the pretreatment liquid comprising:
a multivalent metal salt; and
an aqueous medium,
wherein a concentration of the multivalent metal salt has an absolute molecular mass in a range of 0.025 mol/kg or more to 0.06 mol/kg or less,
wherein the multivalent metal salt is selected from one of calcium chloride and calcium acetate, and
wherein the attachment amount of the pretreatment liquid is in a range of 0.02 g/cm 2 or more to 0.5 g/cm 2 or less.

2. The pretreatment liquid for ink jet textile printing according to claim 1 , wherein metal ions that configure the multivalent metal salt are at least one of calcium ions and magnesium ions.

3. The pretreatment liquid for ink jet textile printing according to claim 1 , wherein anions that configure the multivalent metal salt are chlorine ions.

4. The pretreatment liquid for ink jet textile printing according to claim 1 , wherein a content of resin is 3.5 mass % or less.

5. A textile printing method, comprising:
applying the pretreatment liquid according to claim 1 to at least a partial region of a fabric; and
applying an ink composition for ink jet textile printing to at least a portion of the region to which the pretreatment liquid is applied.

6. A textile printing method, comprising:
applying the pretreatment liquid according to claim 2 to at least a partial region of a fabric; and
applying an ink composition for ink jet textile printing to at least a portion of the region to which the pretreatment liquid is applied.

7. A textile printing method, comprising:
applying the pretreatment liquid according to claim 3 to at least a partial region of a fabric; and
applying an ink composition for ink jet textile printing to at least a portion of the region to which the pretreatment liquid is applied.

8. A textile printing method, comprising:
applying the pretreatment liquid according to claim 4 to at least a partial region of a fabric; and
applying an ink composition for ink jet textile printing to at least a portion of the region to which the pretreatment liquid is applied.

9. The textile printing method according to claim 5 , further comprising:
heating the ink composition applied to the fabric.

10. The textile printing method according to claim 9 ,
wherein the heating temperature in the heating is 160° C. or more and 200° C. or less.

11. The textile printing method according to claim 5 ,
wherein the attachment amount of the multivalent metal salt included in the pretreatment liquid applied to the fabric is 1.6 μmol/cm 2 or more and 6 μmol/cm 2 or less.

12. The textile printing method according to claim 5 ,
wherein the method is performed using a fabric with a brightness (L*) of 70 or more.

13. The textile printing method according to claim 5 ,
wherein the attachment amount of the ink composition applied to the fabric is 1.5 mg/cm 2 or more and 6 mg/cm 2 or less.

14. The textile printing method according to claim 5 ,
wherein the ink composition contains a coloring material other than a white coloring material.

15. The textile printing method according to claim 1 , wherein the viscosity of the pretreatment liquid at 20° C. is 30 mPa·s or less.

16. The pretreatment liquid for ink jet textile printing according to claim 1 , wherein the concentration of the multivalent metal salt is within a range of 0.04 mol/kg or more and 0.06 mol/kg or less.
