摘要： A non-white textile printing ink jet ink composition according to the present disclosure contains a pigment, a resin particle, an acetylene-based surfactant having an HLB value of 6 or more and 10 or less, and water, wherein a content of the acetylene-based surfactant is 0.5% by mass or more and 2.0% by mass or less relative to a total amount of the ink composition, and the ink composition is used for a fabric having water absorbency evaluated using a method described below is 1 or more,



method:
a test fabric cut into 2 cm square is mounted on a water surface in a glass bottle which has a volume of 50 mL and in which 30 mL of pure water is introduced so that a height from a bottom to the water surface is 4 cm, a fabric surface being set to be parallel to the water surface, and a time elapsed from the fabric being mounted until a portion of the fabric reaching the bottom of the glass bottle is denoted as water absorbency in seconds.

摘要： An ink jet recording method according to an embodiment of the present disclosure includes a reaction liquid attachment step of attaching a reaction liquid to a fabric and an ink attachment step of attaching a white ink composition to the fabric with the attached reaction liquid, wherein the reaction liquid contains one or more selected from a polyvalent metal salt, a cationic polymer, and an organic acid as an aggregation agent, the white ink composition contains one or both of a white pigment and a resin particle, the reaction liquid attachment step and the ink attachment step are performed by an ink jet method, the ink jet method performs main scanning a plurality of times, the main scanning performing recording by moving an ink jet head in a direction perpendicular to a transport direction of the fabric, the reaction liquid and the white ink composition are attached to the same scanning region of the fabric by the same main scanning, the same main scanning is performed a plurality of times with respect to the same scanning region, and



(amount of attachment in first pass)>(amount of attachment in nth pass)
(amount of attachment in first pass)+(amount of attachment in nth pass)≥20 mg/inch2,
where a total amount of attachment per unit area of the reaction liquid and the white ink composition that are attached to the fabric by the first main scanning with respect to the same scanning region is denoted by “amount of attachment in first pass”, and a total amount of attachment per unit area of the reaction liquid and the white ink composition that are attached to the fabric by the nth main scanning is denoted by “amount of attachment in nth pass”, n being an integer of 2 or more.
