    摘要： A method of driving a liquid ejection head adapted to apply a voltage to the liquid ejection head to eject a liquid including a polymer is provided. The method includes raising the voltage from a first voltage to a second voltage; raising the voltage from the second voltage to a third voltage at a gradient larger than that in raising the voltage from the first to the second voltage, and then holding the voltage at the third voltage; dropping the voltage from the third voltage to a fourth voltage, and then holding the voltage at the fourth voltage; raising the voltage from the fourth voltage to a fifth voltage, and then holding the voltage at the fifth voltage; dropping the voltage from the fifth voltage to a sixth voltage, and then holding the voltage at the sixth voltage; and raising the voltage from the sixth voltage to a seventh voltage.

    摘要： An ink jet textile printing ink contains 5% by mass to 20% by mass of a water-soluble dye, water, a water-soluble organic solvent, and active carbon particles. The active carbon particles include particles having a particle size of 50 nm to 1000 nm, and the active carbon particles having the particle size of 50 nm to 1000 nm are contained in a proportion of 500 to 300000 particles per milliliter. Also, the active carbon particles may include particles having a particle size of 50 nm to 200 nm, and the active carbon particles having a particle size of 50 nm to 200 nm may be contained in a proportion of 2000 to 30000 particles per milliliter. The active carbon particles may have an average particle size in the range of 100 nm to 600 nm.
