The invention discloses a colorful PU leather production process. The colorful PU leather production process comprises the following steps: firstly, preparing a wet-type semi-finished product, enabling a non-woven fabric to pass through a pre-solidifying tank, then coating the surface of the non-woven fabric with a layer of coating material, then successively carrying out curing and water-washingtreatment, and then drying to obtain a wet-type semi-finished product; secondly, successively coating the surface of release paper with a shell fabric and a bottom material, after pre-heating, pressing the bottom material and the wet-type semi-finished product, and then drying to obtain a semi-finished product; and finally, coating the semi-finished product through a rolling head with a coating material having flickering pieces, and then drying to obtain a finished product. Base cloth is subjected to special pre-solidification treatment and coating treatment through the coating head, the prepared base cloth has high resilience characteristic and folding resistance, after the base cloth is compounded with the shell fabric and the bottom material, the leather can recover the state before deformation after external force on the leather disappears, and by roll coating of a special material, the leather has dazzling surface and a glossy bright effect.
