Abstract

The description relates to solvent free films and textiles that receive the solvent free films.

First claim

The invention claimed is:

1. A device, comprising:
first and second spaced apart surfaces that define a constrained thickness of the device; and,
an input mechanism positioned relative to the first and second surfaces, and wherein at least one of the first and second surfaces is defined at least in part by a coated textile that is bound by a pressure sensitive adhesive to a solvent free film comprising a blend consisting of Polycarbonate, Polyethylene, Siloxane, Wax, and Fluoropolymer and that is essentially free from organic solvent residue.

2. The device of claim 1 , wherein the solvent free film is free from organic solvent residue.

3. The device of claim 2 , wherein the coated textile is less than 1 millimeter thick, or wherein the solvent free film is less than 50 microns thick.

4. The device of claim 1 , wherein the coated textile defines the first surface.

5. The device of claim 4 , wherein a second textile defines the second surface.

6. The device of claim 5 , wherein the second textile is coated with a second solvent free coating comprising Polycarbonate, Polyethylene, Siloxane, Wax, and Fluoropolymer, without organic solvent residue.

7. The device of claim 6 , wherein the second solvent free coating comprises equal percentages of Polycarbonate, Polyethylene, Siloxane, Wax, and Fluoropolymer, as the solvent free coating.

8. The device of claim 1 , wherein the input mechanism comprises a keyboard and the coated textile is positioned as a palm or arm rest for a user of the device.

9. The device of claim 1 , wherein the input mechanism comprises a touch-sensitive display and the coated textile is positioned on a backside of the touch-sensitive display.

10. The device of claim 1 , wherein a single textile covers at least portions of both the first and second surfaces, and wherein the single textile is coated to form the coated textile on both the first and second surfaces or wherein the single textile is coated to form the coated textile on one of the first and second surfaces and the other of the first and second surfaces is uncoated or comprises a different coating.

11. A keyboard, comprising:
first and second spaced apart surfaces that define a constrained thickness;
an input mechanism positioned on the first surface, a remainder of the first surface defined at least in part by a coated textile that includes a first solvent free coating comprising a first blend consisting essentially of Polycarbonate, Polyethylene, Siloxane, Wax, and Fluoropolymer; and
a second textile positioned on the second surface and comprising a second solvent free coating comprising a second blend consisting essentially of Polycarbonate, Polyethylene, Siloxane, Wax, and Fluoropolymer at equal percentages to the first blend.

12. The keyboard of claim 11 , wherein the first solvent free coating further comprises an antimicrobial compound.

13. The keyboard of claim 12 , wherein the antimicrobial compound comprises Silver, Copper, or Zinc.

14. The keyboard of claim 11 , wherein the first solvent free coating further comprises an essential oil.

15. A device, comprising:
a first surface that is covered in part by a coated textile; and,
an input mechanism positioned on the first surface, the coated textile includes a pressure sensitive adhesive secured to a solvent free film comprising a blend consisting essentially of Polycarbonate, Polyethylene, Siloxane, Wax, and Fluoropolymer and that is essentially free from organic solvent residue.

16. The device of claim 15 , further comprising a second surface that opposes the first surface, and wherein at least a portion of the second surface is also defined by the coated textile.
