Abstract

The invention pertains to a method to removably connect a carpet product having a pile side and a fibrous back side to a surface, wherein the method comprises the step of adhering a double face tape with a first side of the tape to the fibrous back side of the carpet product and connecting the carpet product to the surface by adhering the second side of the double face tape to the surface, the first side of said double face tape is provided with multiple hooks extending from this side and having a length of 0.1-10 mm, and the second side of said double face tape is provided with multiple adhesive nano fibres extending from the second side, each fibre having a distal tip that has a surface extending perpendicular to the longitudinal direction of the fibre, the surface having a diameter of 1-900 nm. The invention also pertains to a carpet product and double face tape for use in the above described method.

First claim

The invention claimed is:

1. A method to removably connect a carpet product having a pile side and a fibrous back side to a surface, wherein the method comprises the step of adhering a double face tape with a first side of the tape to the fibrous back side of the carpet product and connecting the carpet product to the surface by adhering a second side of the double face tape to the surface, the first side of said double face tape is provided with multiple hooks extending from the first side and having a length of 0.1-10 mm, and the second side of said double face tape is provided with multiple adhesive nano fibres extending from the second side, each fibre having a distal tip that has a surface extending perpendicular to the longitudinal direction of the fibre, the surface of the distal tip having a diameter of 1-900 nm.

2. A method according to claim 1 , wherein the fibrous back side of the carpet product is partly covered with the double face tape.

3. A method according to claim 2 , wherein the fibrous back side of the carpet product is covered adjacent its circumference.

4. A method according to claim 1 , wherein after a period of time during which the carpet product is connected, the carpet product is removed from the surface and thereafter processed.

5. A method according to claim 4 , wherein before the carpet product is processed the double face tape is removed from the fibrous back side of the carpet product.

6. A carpet product having a pile side and a fibrous back side, to which fibrous back side a double face tape is adhered with a first side of that double face tape, the first side of said double face tape is provided with multiple hooks extending from the first side and having a length of 0.1-10 mm, and a second side of said double face tape is provided with multiple adhesive nano fibres extending from the second side, each fibre having a distal tip that has a surface extending perpendicular to the longitudinal direction of the fibre, the surface having a diameter of 1-900 nm.

7. A carpet product according to claim 6 , wherein the fibrous back side of the carpet product is partly covered with the double face tape.

8. A carpet product according to claim 7 , wherein the fibrous back side of the carpet product is covered adjacent its circumference.

9. Double face tape, a first side of which tape is provided with multiple hooks extending from the first side and having a length of 0.1-10 mm, a second side of which is provided with multiple adhesive nano fibres extending from the second side, each fibre having a distal tip that has a surface running in parallel with the tape, the surface having a diameter of 1-900 nm.

10. A double face tape according to claim 9 , wherein both the hooks and fibres are made of synthetic polymer.

11. A double face tape according to claim 10 , wherein the hooks and fibres are made of polyester.

12. A double face tape according to claim 9 , wherein the tape comprises two separate layers, a first layer carrying the hooks and a second layer carrying the nano fibres, wherein the layers are mechanically connected using an intermediate hot melt adhesive.

13. A double face tape according to claim 12 , wherein the hot melt adhesive is a polyester adhesive.
