Abstract

The invention discloses a production process of discolored leather. The prepared discoloration slurry is uniformly coated on release paper to form a discolored layer, and then an adhesive is uniformly coated on the dried discolored layer, and then the layers are sequentially coated The release paper with discolored pulp and adhesive is attached to the leather as the leather blank, and the adhesive-coated side of the release paper is pressed onto the leather with a pressure of 80-100kg, and then the release paper is torn off. paper to obtain the semi-finished product of the color-changing leather; finally, the color-changing layer of the obtained semi-finished product is covered with a layer of high-temperature resistant oil paper, and rolled to obtain the color-changing leather. The invention provides a production process for discolored leather, and the produced discolored leather has the characteristics of good discoloration effect and long discoloration reversibility life.

Description

technical field [0001] The invention relates to the technical production field of leather, in particular to a production process of discoloration leather. Background technique [0002] Color-changing leather usually refers to artificial leather that changes color under changes in temperature or pressure. Stress-changing leather is one of the representatives of color-changing leather. The deformed part will show a color change, and with the change of the deformation gradient, the color will show a gradual change from light to dark, which can give people a natural and soft feeling. Once the external force is removed, the color of the leather will naturally return to its original state. The research on the production process of photosensitive and temperature-sensitive reversible discoloration leather is also one of the hotspots in the leather industry. At present, this kind of discoloration leather has problems such as poor discoloration effect and short reversible life of dis...
