Abstract
Provided are a textile printing ink set including a pretreatment liquid including a quaternary ammonium cation having a molecular weight of 3000 or less, and an ink composition including a water-insoluble dye, a dispersing agent, and water, wherein a content of the quaternary ammonium cation relative to a total amount of the pretreatment liquid is 5 mass % to 20 mass %; and a textile printing method.
Claims7
A textile printing ink set comprising:
- a pretreatment liquid comprising a quaternary ammonium cation having a molecular weight of 3000 or less;
- and
- an ink composition comprising a water-insoluble dye, a water-soluble dispersing agent, and water,
- wherein the water-soluble dispersing agent is a urethane resin which disperses the water-insoluble dye in the water,
- wherein a content of the water-insoluble dye relative to a total amount of the ink composition is 1 mass % to 10 mass %,
- wherein a content of the quaternary ammonium cation relative to a total amount of the pretreatment liquid is 5 mass % to 20 mass %,
- wherein the quaternary ammonium cation has an aromatic ring, which is a benzene ring, naphthalene ring, or anthracene ring, and
- wherein upon contact of the ink composition with the quaternary ammonium cation, the quaternary ammonium cation turns the water-soluble dispersing agent to become insoluble in the water, causing aggregation of the water-insoluble dye.
