Abstract

The invention discloses a leather printing and dyeing process, and belongs to the technical field of textile leather printing and dyeing. By additionally arranging a leather winding piece and elastic extrusion pieces, when leather is printed and dyed, the leather winding piece is used for clamping and winding the leather leftwards and rightwards, and the leather is dip-dyed in the friction movement with the leather winding piece, so that the printing and dyeing permeability is improved; and meanwhile, under the action of a magnetic field, the multiple elastic extrusion pieces distributed up and down get close to each other and make impact contact with the upper end and the lower end of the leather, the elastic extrusion pieces suck dye and release the dye after making contact with the leather, and air overflows from the end face of the leather during extrusion, so that the dye is further promoted to permeate into cracks of the leather, the printing and dyeing effect is improved, and the printing and dyeing time is shortened.
