Abstract

An inkjet textile printing treatment liquid contains an aqueous medium and a pH sliding agent. An inkjet textile printing apparatus includes a recording head that ejects an ink toward an image formation area of a textile printing target and a first treatment head that ejects a first treatment liquid toward at least the image formation area of the textile printing target. The first treatment liquid is the above-described inkjet textile printing treatment liquid. An inkjet textile printing method incudes: inkjetting an ink toward an image formation area of a textile printing target; and inkjetting a first treatment liquid toward at least the image formation area of the textile printing target. The first treatment liquid is the above-described inkjet textile printing treatment liquid.

First claim

1 . An inkjet textile printing treatment liquid comprising:
an aqueous medium; a pH sliding agent; and emulsified particles containing a silicone oil, wherein the inkjet textile printing treatment liquid is a post-treatment liquid for post-treatment of inkjet textile printing.

2 . The inkjet textile printing treatment liquid according to claim 1 , wherein
the pH sliding agent contains an ammonium salt, a sulfonate quaternary ammonium salt, or a sulfonic acid ester.

3 . The inkjet textile printing treatment liquid according to claim 2 , wherein
the ammonium salt includes ammonium sulfate or ammonium malate, the sulfonate quaternary ammonium salt includes tetrabutylammonium trifluoromethanesulfonate, and the sulfonic acid ester includes isobutyl dodecylbenzenesulfonate.

4 . The inkjet textile printing treatment liquid according to claim 1 , wherein
a percentage content of the pH sliding agent is at least 0.1% by mass and no greater than 10.0% by mass.

5 - 6 . (canceled)

7 . The inkjet textile printing treatment liquid according to claim 1 , wherein
the emulsified particles have an average particle diameter of at least 100 nm and no greater than 250 nm.

8 . The inkjet textile printing treatment liquid according to claim 1 , wherein
the inkjet textile printing treatment liquid contains the emulsified particles dispersed therein and does not contain a dispersant.

9 . An inkjet textile printing apparatus comprising:
a recording head configured to eject an ink toward an image formation area of a textile printing target; a first treatment head configured to eject a first treatment liquid toward at least the image formation area of the textile printing target, and a second treatment head configured to eject a second treatment liquid toward at least the image formation area of the textile printing target, wherein the first treatment liquid is the inkjet textile printing treatment liquid according to claim 1 , and the second treatment liquid is a pretreatment liquid containing a cationic component.

10 - 11 . (canceled)

12 . An inkjet textile printing method comprising:
inkjetting an ink toward an image formation area of a textile printing target; inkjetting a first treatment liquid toward at least the image formation area of the textile printing target; heating the textile printing target after the inkjetting an ink and the inkjetting a first treatment liquid; and ejecting a second treatment liquid toward at least the image formation area of the textile printing target, wherein the first treatment liquid is the inkjet textile printing treatment liquid according to claim 1 , and the second treatment liquid is a pretreatment liquid containing a cationic component.

13 . (canceled)

14 . The inkjet textile printing method according to claim 12 , wherein an amount of the first treatment liquid ejected is at least 15 g/m2 and no greater than 30 g/m2.

15 . A textile print comprising an image formed thereon, wherein
the image contains a component derived from the inkjet textile printing treatment liquid according to claim 1 and a component derived from an ink.
