The suede composite PVC pads obtained in examples 1 to 4 and comparative examples 1 to 2 were subjected to dry-rubbing and wet-rubbing tests, respectively, according to the method of EN ISO105X12:2002, and the results are shown in the following table:
TABLE 3 rubbing fastness test results
| Example 1 | Example 2 | Example 3 | |
| Dry rub rating | 4 | 3 | 4 |
| Wet rub rating | 3 | 3 | 4 |
| Example 4 | Comparative example 1 | Comparative example 2 | |
| Dry rub rating | 4 | 4 | 4 |
| Wet rub rating | 3 | 3 | 3 |
As can be seen from the above table, within the temperature range of the thermal sublimation transfer printing adopted by the application, the dry wiping and wet wiping grades can meet the requirements.
4. Resilience performance
The suede composite PVC pads obtained in examples 1 to 4 and comparative examples 1 to 2 were subjected to a rebound property test using a method of ISO4662 with the suede layer facing upward, and the results are shown in the following table:
TABLE 4 rebound test results
| Example 1 | Example 2 | Example 3 | |
| Rebound, is% | 13 | 13 | 14 |
| Example 4 | Comparative example 1 | Comparative example 2 | |
| Rebound, is% | 13 | 10 | 11 |
As is clear from the above table, comparative examples 1-2 show a significant reduction in the rebound performance compared to examples 1-4.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
