Abstract: A fabric treatment agent that is used in textile printing with a sublimable color material includes a color-material scavenging compound having an Rf value of 0.7 or less according to paper chromatography performed under following conditions. In Procedure 1, cellulose filter paper is impregnated with a 10% solution of the color-material scavenging compound and then dried to prepare a carrier. In Procedure 2, a 0.1% solution of a sublimable color material in tetrahydrofuran is spotted on the carrier and then dried to prepare a development sample. In Procedure 3, the development sample is developed using acetonitrile as a solvent for 3 minutes at 25° C. In Procedure 4, the Rf value is calculated by a following formula: R ⁢ f = ( distance ⁢ travelled ⁢ by ⁢ the ⁢ sublimable ⁢ color ⁢ material ) ( distance ⁢ travelled ⁢ by ⁢ acetonitrile ) .

Abstract: The pretreatment liquid of the present invention is applicable for a fabric to be used for inkjet textile printing, and the pretreatment liquid contains a block copolymer including a hydrophobic block derived from a hydrophobic resin having an SP value of less than 11 and a hydrophilic block derived from a hydrophilic resin having an SP value of 11 or more, with the difference between the SP values of the hydrophobic resin and the hydrophilic resin of 1.0 or more; and water.
