Abstract

A textile is dyed by treating the textile with a composition containing 2D nano and/or microparticles of carbon and by dyeing the textile with a dye that is different from said carbon particles.

First claim

The invention claimed is:

1. A process of dyeing a textile, comprising the step of preparing a composition containing carbon particles and applying said composition to textiles, characterized in that at least part of said carbon particles are carbon nanoparticles and/or carbon microparticles having a thickness in nanometers and having a length of the major axis comprised in the range of 0.01 to 80 microns.

2. A process according to claim 1 , wherein said carbon particles have dimensions of 0.1 to 20 microns.

3. A process according to claim 1 , further comprising the step of dyeing said textile with at least one additional dye which is different from said carbon nanoparticles and said carbon microparticles.

4. A process according to claim 3 , wherein said dye contains indigo or an indigo derivative which is applied to said textile, with a rope-dyeing process when said textile is a yarn and a dyeing process when said textile is a fabric.

5. A process according to claim 1 , wherein said composition containing carbon particles is applied more than once to said textiles.

6. A process according to claim 1 , wherein said textile is selected from yarns and fabrics.

7. A process according to claim 6 , further comprising the step of treating said fabric in a finishing step to remove part of at least said additional dye.

8. A process according to claim 1 , wherein said carbon particles are selected from graphene, graphite and mixtures thereof.

9. A dyed textile as obtainable according to the process of claim 1 , comprising a plurality of carbon nanoparticles and/or carbon microparticles having a thickness in nanometers and having a length of the major axis comprised in the range of 0.01 to 80 microns.

10. A dyed textile according to claim 9 further comprising an additional dye, different from carbon particles.

11. A dyed textile according to claim 10 , wherein said additional dye comprises indigo or an indigo derivative.

12. A dyed textile according to claim 11 , wherein at least said textile is ring-dyed.

13. A garment comprising a textile according to claim 10 .

14. A garment according to claim 13 , wherein part of the additional dye or of said additional dye and of said carbon particles has been removed from the textile.

15. A composition for a process of dyeing a textile according to claim 1 , comprising carbon particles and at least a binder and/or an auxiliary chemical, said composition being configured to apply said carbon particles to a textile, characterized in that said carbon particles are carbon nanoparticles and/or carbon microparticles having a thickness in nanometers and having a length of the major axis comprised in the range of 0.01 to 80 microns.

16. A method for dyeing a textile with carbon nano or microparticles to provide an undercoating for the application of a dye, said carbon nano or microparticles having a thickness in nanometers and having a length of the major axis comprised in the range of 0.01 to 80 microns.
