Abstract

An ink jet recording method according to the present disclosure is a method for recording on a textile including ejecting a white ink composition for ink jet textile printing containing a white pigment and water with an ink jet recording apparatus, wherein the white ink composition is ejected as 9 ng or less of droplets from a nozzle, and the droplets are ejected and recorded on the textile such that a droplet ejected later has a higher flight speed than a droplet ejected earlier and the droplets coalesce before landing on the textile.

Claims (16)

1. An ink jet recording method for recording on a textile comprising ejecting a white ink composition for ink jet textile printing containing a white pigment and water with an ink jet recording apparatus, wherein

the white ink composition is ejected as 9 ng or less of droplets from a nozzle, and

the droplets are ejected and recorded on the textile such that a droplet ejected later has a higher flight speed than a droplet ejected earlier and the droplets coalesce before landing on the textile.

2. The ink jet recording method according to claim 1 , wherein

the textile is treated with a pretreatment agent containing at least one coagulant selected from polyvalent metal salts, cationic polymers, and cationic surfactants.

3. The ink jet recording method according to claim 2 , wherein

the white ink composition contains 8% or more by mass of a component that reacts with the pretreatment agent.

4. The ink jet recording method according to claim 3 , wherein

the component that reacts with the pretreatment agent is composed of resin particles.

5. The ink jet recording method according to claim 1 , wherein the ink jet recording apparatus includes

a nozzle array configured to eject the white ink composition located upstream in a sub-scanning direction, and

a nozzle array configured to eject a non-white ink composition for ink jet textile printing containing a non-white pigment and water located downstream in the sub-scanning direction.

6. The ink jet recording method according to claim 1 , wherein

the white ink composition has a density of 1.12 g/cm 3 or more.

7. The ink jet recording method according to claim 1 , wherein

the white pigment is composed of titanium oxide particles.
