Abstract

The present invention relates to a textile layer comprising a first coating, wherein the first coating is a cured coating and comprises a polyurethane. The textile layer further comprises a second coating, wherein the second coating comprises at least one coloring agent and is arranged on the cured first coating. The polyurethane based cured first coating is transparent.

First claim

That which is claimed is:

1. A method of coloring a textile layer comprising the steps of:
applying a first coating to the textile layer, wherein the first coating comprises a polyurethane;
curing the first coating, wherein the first coating is transparent after the curing; and
applying a second coating to the cured first coating, wherein the second coating comprises at least one coloring agent; and wherein the second coating is arranged on top of the first coating.

2. The method according to claim 1 , wherein a thickness of the first coating is between 20 and 120 μm after the curing.

3. The method according to claim 1 , wherein a thickness of the first coating is between 40 and 110 μm after the curing.

4. The method according to claim 1 , wherein a thickness of the first coating is between 80 and 95 μm after the curing.

5. The method according to claim 1 , wherein curing comprises applying heat to the textile layer at a temperature between 20° C. and 150° C.

6. The method according to claim 1 , wherein curing comprises applying heat to the textile layer at a temperature between 40° C. and 130° C.

7. The method according to claim 1 , wherein curing comprises applying heat to the textile layer at a temperature between 60° C. and 110° C.

8. The method according to claim 1 , wherein curing comprises applying heat to the textile layer at a temperature between 80° C. and 100° C.

9. The method according to claim 2 , wherein the curing comprises using an oven, a fan, a hot air blower, an infrared radiator or combinations thereof.

10. The method according to claim 5 , wherein the curing further comprises applying the heat to the textile layer for less than 60 minutes.

11. The method according to claim 1 , wherein the applying the first and/or second coating comprises applying the first and/or second coating using a spray gun, a silicon pad or an ink-jet.

12. The method according to claim 1 , wherein the method further comprises adapting a rheology of the first coating depending on a material of the textile layer.

13. The method according to claim 1 , wherein the second coating further comprises a polyurethane.

14. A textile layer comprising:
a first coating, wherein the first coating is a cured first coating and comprises a polyurethane;
a second coating, wherein the second coating comprises at least one coloring agent and is arranged on top of the cured first coating; and
wherein the cured first coating is transparent.

15. The textile layer according to claim 14 , wherein a thickness of the first coating is between 20 and 120 μm after the curing.

16. The textile layer according to claim 14 , wherein a thickness of the first coating is between 40 and 110 μm after the curing.

17. The textile layer according to claim 14 , wherein a thickness of the first coating is between 80 and 95 μm after the curing.

18. The textile layer according to 14 , wherein the first and/or second coating has been applied using a spray gun, a silicon pad or an ink-jet.

19. The textile layer according to claim 14 , wherein a rheology of the first coating is adapted depending on a material of the textile layer.

20. The textile layer according to claim 14 , wherein the second coating comprises a polyurethane.
