Abstract

The invention relates to a multi-color carving process for leather. The process comprises (1) cutting leather to be carved with a pattern or a logo into a cut piece and marking the part to be carved; (2) uniformly spraying a layer of tearable rubber onto the surface of the leather to be printed with a pattern; (3) designing a to-be-carved pattern and transferring to the control computer of a laser carving machine; (4) positioning the leather to be printed with a pattern at a corresponding position of the operating board of the laser machine; (5) instructing the carving machine to directly carve the pattern on the leather surface; (6) directly spraying or printing a required color onto the carved position by use of a spray gun or a digital spraying machine; and (7) stripping off the tearable rubber. According to the invention, tearable rubber is firstly sprayed to fully seal the leather surface, and then color spray dying is adopted, to effectively solve the technical difficulty of failure to color the carved leather; the pattern has strong stereoscopic effects and colorful effects; and the invention also has the advantages of wide accessibility of raw materials, abundant patterns, strong layered effects, good color fastness, good environment protection and no pollution.

Description
