    Abstract: A textile printing method for printing on a fabric, the fabric being a nonwoven fabric containing synthetic fibers. includes a first adhering step of adhering to the fabric by ejecting a dyeing ink by an ink jet method, and a second adhering step of adhering a non-dyeing ink to the fabric. The dyeing ink contains a disperse dye, a water-soluble organic solvent, and water, and the non-dyeing ink contains a water-soluble organic solvent and water. The water-soluble organic solvent contained in the non-dyeing ink contains a glycol-based organic solvent having a HSP value of 13.6 or more, and the content of the glycol-based organic solvent is 80% by mass or more relative to the total amount of the organic solvent contained in the non-dyeing ink. The adhesion position of the dyeing ink and the adhesion position of the non-dyeing ink are at least partially overlapped each other.
