Embodiment 1

[0032] A kind of synthetic leather of the embodiment of the present invention, described leather comprises polyamide base cloth layer and the leather layer that is arranged on described polyamide base cloth layer;

[0033] The polyamide base cloth layer is dipped and pressed in an aqueous solution containing α-cyclodextrin, trimethyl citrate and dihydrogen phosphate, and baked at 130°C for 20 minutes;

[0034] The leather layer includes the following raw material components in parts by mass:

[0035] 80 parts of polyurethane; 20 parts of polyacrylic resin; 15 parts of gelatin; 6 parts of elastic resin; 0.5 parts of sodium polymethacrylate.

[0036] The preparation method of above-mentioned synthetic leather comprises the following steps:

[0037] (1) The polyamide base cloth layer is fully washed with water, then soaked and pressed in an aqueous solution containing 85g / L cyclodextrin, 135g / L trimethyl citrate and 80g / L dihydrogen phosphate, after the soaked and pressed treatm...

Embodiment 2

[0042] The only difference between Example 2 and Example 1 is that the cyclodextrin is β-cyclodextrin.

Embodiment 3

[0044] The only difference between Example 3 and Example 1 is that the cyclodextrin is hydroxypropyl-β-cyclodextrin.
