Artificial leather with even imprinted texture and method for making the same

Abstract

There is disclosed artificial leather with even imprinted texture and a method for making the same. The method includes the steps of: making a thermally imprintable polyurethane resin foil into a first substrate; providing at least one polyurethane resin layer on the first substrate in a spotted manner or by rolling or spraying; making pre-determined texture or graphics on the polyurethane resin layer by imprinting; making non-woven fabric, elastic fabric, woven fabric or ultra-fine fiber materials into a second substrate; and providing the first substrate on the second substrate by adhesion so as to form the artificial leather with even imprinted texture.

Claims

1. A method for making artificial leather with even imprinted texture, the method comprising the steps of: making a polyurethane resin foil into a first substrate with a front surface and a rear surface;coating the front surface of the first substrate with at least one polyurethane resin layer so as to form a superficial layer;imprinting the front surface of the polyurethane resin layer with texture; andproviding a second substrate beneath the rear surface of the first substrate so as to form the artificial leather with even imprinted texture.

2. The method according to claim 1 wherein the first substrate is preferably made of a thermally imprintable polyurethane resin foil.

3. The method according to claim 1 wherein the thickness of the first substrate is of 0.1 to 2.0 mm.

4. The method according to claim 1 wherein the polyurethane resin layer is provided on the front surface of the first substrate in a spotted manner or by rolling or spraying at a quantity of 20 to 300 g/m2.

5. The method according to claim 1 wherein the step of imprinting is conducted at 40 to 280 Celsius degrees.

6. The method according to claim 1 comprising the step of finishing the imprinted front surface so as to change the color, touch-difficult-feeling and lighting of the texture of the polyurethane resin foil after the step of imprinting.

7. The method according to claim 6 wherein the step of finishing is done with at least one of polyamide, polyurethane, silicone-containing chemical composition and wax-containing chemical composition at a quantity of 40 to 300 g/m2.

8. The method according to claim 1 wherein the second substrate is bonded to the rear surface of the first substrate in a spotted manner or by rolling or spraying at a quantity of 20 to 300 g/m2.

9. The method according to claim 1 wherein the second substrate is selected from non-woven fabric, elastic fabric, woven fabric, split leather and ultra fine fiber.

10. The method according to claim 1 wherein the front surface of the first substrate is imprinted by a roller formed with texture and graphics.

11. Artificial leather with even imprinted texture, the artificial leather comprising: a first substrate made of a polyurethane resin foil and with a front surface and a rear surface;at least one superficial layer coated on a first substrate and made with imprinted texture; anda second substrate bonded to the rear surface of the first substrate.

12. The artificial leather according to claim 11 wherein the imprinted texture reaches the first substrate.

13. The artificial leather according to claim 11 wherein the thickness of the first substrate is 0.1 to 2.0 mm.

14. The artificial leather according to claim 11 wherein the superficial layer is a polyurethane layer.

15. The artificial leather according to claim 11 wherein the first substrate is a thermally imprintable polyurethane foil.

16. The artificial leather according to claim 11 comprising a finished layer on the front surface of the first substrate so as to change the color, touch-difficult-feeling and lighting of the texture of the imprinted texture.

17. The artificial leather according to claim 16 wherein the finished layer comprises composition selected from polyamide, polyester, silicone-containing chemical composition and wax-containing chemical composition.

18. The artificial leather according to claim 11 wherein the second substrate is selected from non-woven fabric, elastic fabric, split leather, woven fabric and ultra fine fiber.

19. The method according to claim 2 wherein the thickness of the first substrate is of 0.1 to 2.0 mm.
