Preparation process of high-color-fastness imitation leather local gold stamping fabric

The invention discloses a preparation process of a high-color-fastness local gold-stamped imitation leather fabric, which adopts sublimation transfer printing and comprises the following steps: firstly, selecting proper disperse dye, aleurone, alcohol, benzene and other solvents, grinding with resin to prepare ink, and printing on tough paper to prepare transfer paper; during printing, one side of the transfer paper with the color paste is overlapped with the fabric, and the disperse dye sublimates to become gaseous through high-temperature hot pressing and is transferred to the fabric from the paper. And water washing treatment is not needed after printing, so that sewage is not generated, and the effects of bright color, distinct gradation and delicate flower shape can be achieved. An ultraviolet light absorber is added in transfer printing, the performance of the ultraviolet light absorber is superior to that of other chromophores in polymer molecules, ultraviolet light can be selectively and strongly abso
