and (3) testing color fastness: testing by adopting dry friction and wet friction modes respectively according to the regulations of GB/T3920-;
and (3) softness testing: selecting a test ring with the inner diameter of 25mm according to the specification of QB/T4870-2015, and testing the softness value of the test ring;
the test results are shown in table 1 below:
TABLE 1
Dry rub colour fastness/grade Wet rub colour fastness/grade Softness value
Example 1 5 5 46
Example 2 4.5 4 40
Example 3 5 5 48
Example 4 5 4.5 43
Comparative example 1 5 4.5 34
Comparative example 2 4 3.5 45
As can be seen from the above Table 1, the sofa leather of the chromatic sofa has high color fastness and better softness, which shows that the color-fixing paint and the color-fixing surface oil used by the invention have better adhesion to leather, good wear resistance and better flexibility; example 1, which has a higher softness value than comparative example 1, illustrates that the color correction paint consists of a component a, a component B and a component C in a weight ratio of 1: 0.5-1: the 0.1-0.5 mixture has little effect on the softness of the cured sofa leather cover. Compared with the comparative example 2, the color fastness of the example 1 is higher, which shows that the drying time and the relative humidity have larger influence on the color fixing surface oil, and the color fixing protection effect on the color fixing paint is better, so that the wear resistance and the color fastness of the chromatography sofa are improved.
The above-described embodiments are preferred implementations of the present invention, and the present invention may be implemented in other ways without departing from the spirit of the present invention.
