[0025] The technical solution of the utility model is further described below in conjunction with the embodiments and drawings.

[0026] like Figures 1 to 3 As shown, a stain-resistant seat leather comprises:

[0027] cortical germ layer 20;

[0028] A spray layer 10, the spray layer 10 is disposed on the cortical germ layer 20;

[0029] in,

[0030] A spray coating 10, on which a base coating 11, a coloring layer 12, and a top coating 13 are sequentially arranged;

[0031] The anti-fouling layer 14 is disposed above the top light layer 13 and is made of fluorine resin.

[0032] Furthermore, the stain-resistant layer 14 is also provided with carboxymethyl cellulose and a cross-linking agent.

[0033] New energy vehicles are currently very popular among young consumers, and the color tone of seat interiors is becoming more and more youthful. Light colors are becoming the main colors, but light-colored leather is not easy to maintain and clean, which has become a problem that needs to be solved urgently.

[0034] In summary, in order to solve the deficiencies in the existing automotive leather structure, the utility model designs a seat leather with a reasonable structure, good use effect and stain resistance.
