Abstract

A textile printing method includes heating a cloth, and applying an ink composition onto the heated cloth by ejecting the ink composition from an ink jet head. The ink composition contains resin fine particles and has a viscosity of 4.5 mPa·s or less at 40° C. and a surface tension of 28 mN/m or less at 40° C.

First claim

What is claimed is:

1. A textile printing method comprising:
a first heating process that includes heating a cloth before applying an ink composition to the cloth, a temperature of the first heating process being in a range between 35° C. to 65° C.;
an applying process that includes applying the ink composition onto the heated cloth by ejecting the ink composition from an ink jet head; and
a second heating process that includes heating the cloth after applying the ink composition, a temperature of the second heating process being in a range between 150° C. to 200° C.,
wherein the ink composition contains resin fine particles and has a viscosity of 4.5 mPa·s or less at 40° C. and a surface tension of 28 mN/m or less at 40° C.

2. The textile printing method according to claim 1 , wherein the viscosity of the ink composition at 20° C. is in the range of 4 mPa·s to 5.5 mPa·s.

3. The textile printing method according to claim 1 , wherein the resin fine particles have a glass transition temperature of 0° C. or less.

4. The textile printing method according to claim 1 , wherein the cloth contains polyester.

5. The textile printing method according to claim 1 , further comprising applying a treatment liquid containing a flocculant capable of aggregating constituents of the ink composition onto the cloth before the applying of the ink composition.

6. The textile printing method according to claim 1 , wherein the ink composition contains a pigment as a coloring material.

7. The textile printing method according to claim 1 , wherein the content of the resin fine particles in the ink composition is in the range of 1% by mass to 20% by mass.

8. The textile printing method according to claim 1 , wherein the ink composition is aqueous.

9. The textile printing method according to claim 1 , wherein the ink composition contains an organic solvent having a normal boiling point of 250° C. or more.

10. The textile printing method according to claim 1 , wherein the ink composition contains at least one of a silicone surfactant and a fluorosurfactant.

11. The textile printing method according to claim 1 , wherein the ink composition contains a polyol compound as an organic solvent, the polyol compound having at least three hydroxy groups.

12. A textile printing apparatus configured to perform the textile printing method as set forth in claim 1 , the textile printing apparatus comprising:
the ink jet head; and
a heating mechanism configured to perform the heating of the cloth.

13. A textile printing apparatus configured to perform the textile printing method as set forth in claim 2 , the textile printing apparatus comprising:
the ink jet head; and
a heating mechanism configured to perform the heating of the cloth.

14. A textile printing apparatus configured to perform the textile printing method as set forth in claim 3 , the textile printing apparatus comprising:
the ink jet head; and
a heating mechanism configured to perform the heating of the cloth.

15. A textile printing apparatus configured to perform the textile printing method as set forth in claim 4 , the textile printing apparatus comprising:
the ink jet head; and
a heating mechanism configured to perform the heating of the cloth.

16. A textile printing apparatus configured to perform the textile printing method as set forth in claim 5 , the textile printing apparatus comprising:
the ink jet head; and
a heating mechanism configured to perform the heating of the cloth.

17. A textile printing apparatus configured to perform the textile printing method as set forth in claim 6 , the textile printing apparatus comprising:
the ink jet head; and
a heating mechanism configured to perform the heating of the cloth.

18. A textile printing apparatus configured to perform the textile printing method as set forth in claim 7 , the textile printing apparatus comprising:
the ink jet head; and
a heating mechanism configured to perform the heating of the cloth.

19. A textile printing apparatus configured to perform the textile printing method as set forth in claim 8 , the textile printing apparatus comprising:
the ink jet head; and
a heating mechanism configured to perform the heating of the cloth.
