[0113] (I) The odor scores and VOC (volatile organic compounds) concentration tests were performed on the bio-based fabrics prepared in Example 1 and Comparative Example 1. The results are shown in Table 1 below.

[0114] Table 1

[0115]

[0116] The odor intensity score is 6 points in total, and the higher the score, the greater the odor intensity. As can be seen from Table 1, the odor intensity score of the bio-based fabric prepared in Example 1 is low, indicating that its odor intensity is low and the user experience is better.

[0117] The VOC concentration includes the concentration of each organic matter in Table 1, and ND means not detected. As can be seen from Table 1, the VOC content of the bio-based fabric prepared in Example 1 is reduced.

[0118] (ii) The bio-based leathers prepared in Example 1 and Comparative Example 1 were subjected to light resistance test, heat resistance test and wear resistance test.

[0119] Lightfastness test conditions: According to GB / T 32088-2015, the test time is 210h, and the sample requirements of bio-based leather are: color fastness ≥ level 4;

[0120] Heat resistance test conditions: set the oven to 100°C, test time is 168h, bio-based leather sample requirements: color fastness ≥ level 4;

[0121] Abrasion resistance test conditions: Test according to QB / T 2726-2005 standard. Sample requirements for bio-based leather: color fastness ≥ level 4, no damage at the seams, and no wear to the foam layer or base fabric layer.

[0122] Table 2

[0123]

[0124] It can be seen from Table 2 that the bio-based leather prepared in Example 2 has better light resistance, heat resistance and wear resistance.

[0125] As can be seen from the above, it can be seen from Table 1 that the bio-based fabric prepared by the embodiment of the present application, which is a bio-based decorative material, has a good smell and a lower VOC, that is, it has a good smell.

[0126] It can be seen from Table 2 that the bio-based leather, a bio-based decorative material, prepared by the embodiment of the present application has good light resistance, heat resistance and wear resistance, that is, has good aging resistance.

[0127] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0128] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims, and the description and drawings can be used to interpret the content of the claims.
