Method for manufacturing wear and tear-indicating product

A method for manufacturing a wear and tear-indicating product, comprising:

• mixing a material component, an ink affinitive material and an ink repulsive material under stirring to form a blank, followed by molding the blank, so as to obtain an ink receiving sheet, wherein a plurality of color indicating areas are formed on the ink receiving sheet, at least one area of the plurality of color indicating areas comprises a higher proportion of the ink affinitive material than a neighboring area of the at least one area of the plurality of color indicating areas;
• disposing a sublimation transfer paper on the ink receiving sheet, the sublimation transfer paper including a sublimation ink deposited thereon;
• heat pressing the sublimation transfer paper on the ink receiving sheet, so that the sublimation ink is released from the sublimation transfer paper, and permeates into the ink receiving sheet so that the sublimation ink is adhered to the material component and the ink affinitive material, so as to obtain a colored ink receiving sheet, the colored ink receiving sheet having a plurality of color indicating areas that contain the ink affinitive material and the sublimation ink permeating into the ink affinitive material;
• and
• removing the sublimation transfer paper from the colored ink receiving sheet so as to obtain the wear and tear-indicating product;
• wherein the at least one area of the plurality of color indicating areas has a higher ink intensity than the neighboring area of the at least one area of the plurality of color indicating areas.
