Embodiment Construction

[0020] As mentioned above, the technical solution provided is to provide a method for making multi-color leather, including the following steps:

[0021] S001 selects the PU material with a thickness of 8 mm as the raw material, and sprays a layer of ink on the PU material;

[0022] S002 Make a knife mold, paint the knife mold with paint, and then use the beer machine to cut the PU material. When cutting the PU material, the corner position must be standard and the sides must be straightened. Use the beer machine to cut the PU material. The PU material is cut by machine, and the knife edge of the knife mold is waxed every 5 times of cutting.

[0023] S003 Make a copper mold according to the required pattern, determine the embossing position on the embossing machine with cardboard, place the copper mold, adjust the embossing force, and heat the copper mold, then release the embossing machine, take out the PU material; the PU material must be laid flat on the embossing machine,...

Abstract

The invention discloses a manufacturing method of multicolored leather. The manufacturing method comprises the following steps of: selecting a PU (Poly Urethane) material; spraying one layer of printing ink on the PU material; manufacturing a cutting die; coloring the cutting die by using paint; then cutting the PU material; manufacturing a copper die according to a needed pattern and determining a pressing and printing position on a pressing and printing machine by using a paperboard; placing the copper die and adjusting pressing and printing intensity; heating the copper die; then loosening the pressing and printing machine and taking the PU material out; polishing the PU material by using a polishing machine; after the polishing machine is started, coating a layer of brushing-off wax on wiping cloth so that the wiping cloth is matched with the brushing-off wax to remove the printing ink on the PU material to expose a bottom color of the PU material; and after the polishing is finished, the colors of the PU material are different, so as to have the effect of restoring ancient ways. The manufacturing method of the multicolored leather disclosed by the invention is good in brushing-off effect and can improve the grade of the leather.

Description

technical field [0001] The invention relates to the field of leather surface treatment, in particular to a method for making multi-color leather with good color rubbing effect and capable of improving the grade of leather. Background technique [0002] Today, leather products of various designs and colors can be seen everywhere in daily life, such as interior decoration, sofa fabrics, car interiors, clothing, footwear and luggage, etc. Some of these leather products are made of natural leather, and a considerable share is made of natural leather. artificial leather and synthetic leather. [0003] People are used to calling the artificial leather produced with PVC resin as PVC artificial leather (abbreviated as artificial leather); the artificial leather produced with PU resin as raw material is called PU artificial leather (abbreviated as PU leather); the artificial leather produced with PU resin and non-woven fabrics as raw materials It is called PU synthetic leather (refe...
