Abstract

An ink jet textile printing recording method including a colored ink attachment step of attaching a liquid droplet of a colored ink composition containing a pigment and an anionic first resin particle to a fabric, a treatment liquid attachment step of attaching a liquid droplet of a treatment liquid containing a polyvalent metal salt to the fabric, and a non-colored ink attachment step of attaching a liquid droplet of a non-colored ink composition containing an anionic second resin particle to the fabric, the colored ink attachment step, in which the treatment liquid attachment step, and the non-colored ink attachment step are performed by an ink jet method, in the ink jet method, main scanning is performed for recording by moving an ink jet head in a direction perpendicular to a transport direction of the fabric, the colored ink composition, the treatment liquid, and the non-colored ink composition are attached to the same scanning region of the fabric by the same main scanning, an attachment amount of the polyvalent metal salt to the fabric is 0.3 (mg/inch 2 ) or more, a content of the second resin particle with respect to a total amount of the non-colored ink composition is higher than a content of the first resin particle with respect to a total amount of the colored ink composition, and an attachment amount of the non-colored ink composition is smaller than an attachment amount of the colored ink composition.

Claims (39)
