Abstract
An ink jet textile printing ink set of the present disclosure includes an ink composition and a process liquid composition, wherein the process liquid composition contains a cationic compound and a compound having one quaternary ammonium in its molecule, and the ink composition contains a pigment and an organic solvent, where the organic solvent is a polyhydric alcohol solvent and the content thereof is 10.0 mass % or more and 55.0 mass % or less.
Claims9
An ink jet textile printing ink set comprising:
- an ink composition;
- and
- a process liquid composition,
- wherein the process liquid composition contains a cationic compound and a compound having one quaternary ammonium in a molecule;
- the compound having one quaternary ammonium in the molecule includes trimethylglycine, and
- the ink composition contains a pigment and an organic solvent, the organic solvent being a polyhydric alcohol solvent and a content of the polyhydric alcohol solvent being 10.0 mass % or more and 55.0 mass % or less.
3 more elements
An ink jet textile printing system comprising:
- a process liquid adhesion unit that adheres a process liquid composition containing a cationic compound and a compound having one quaternary ammonium in a molecule to fabric, the compound having one quaternary ammonium in the molecule including trimethylglycine;
- and
- an ink jet textile printing apparatus that comprises
- an ink jet head including a nozzle for discharging an ink composition containing a pigment and an organic solvent, the organic solvent being a polyhydric alcohol solvent and a content of the polyhydric alcohol solvent being 10.0 mass % or more and 55.0 mass % or less, to adhere the ink composition to the fabric and a circulation passage for circulating the ink composition.
1 more element
An ink jet textile printing method comprising:
- a process liquid adhesion step of adhering a process liquid composition containing a cationic compound and a compound having one quaternary ammonium in a molecule to fabric, the compound having one quaternary ammonium in the molecule including trimethylglycine;
- and
- an ink adhesion step of discharging an ink composition containing a pigment and an organic solvent from a nozzle of an ink jet head to adhere the ink composition to the fabric, where the organic solvent is a polyhydric alcohol solvent and a content of the polyhydric alcohol solvent is 10.0 mass % or more and 55.0 mass % or less.
