Abstract

The present invention involves a solvent vapor transfer device for holding an absorbent pad, which receives and disperses solvent vapors over a lacquer-based residue on a textile. A solvent is poured or dripped into an absorbent pad portion of the vapor transfer box, from which solvent vapors are released. The solvent vapors pass through the vapor transfer box and concentrate in a vapor chamber over the lacquer-based residue and textile. As the solvent vapors come into continuous contact with the lacquer-based residue, the residue begins to dissolve and soften. Upon sufficient dissolution, minute quantities of the liquid solvent may be applied directly to the partially dissolved residue and quickly suctioned into an extraction vacuum. This process may be repeated as necessary to achieve complete removal of the residue.

Claims (35)

1. A method for removing lacquer based residue from a textile surface, including the steps of:

providing a vapor transfer box;

providing an absorbent pad within the vapor transfer box;

placing the vapor transfer box above the textile surface having the lacquer based residue;

applying a liquid solvent to the absorbent pad and preventing the liquid solvent from passing through the absorbent pad and directly onto the textile surface, wherein solvent vapors from the liquid solvent diffuse from the absorbent pad and concentrate within the vapor transfer box over the lacquer based residue;

allowing the solvent vapors within the vapor transfer box to soften the lacquer based residue;

removing the transfer box from the textile surface after the residue has softened; and

removing the lacquer based residue from the textile surface.

2. The method according to claim 1 , wherein the step of removing the lacquer based residue further comprises the step of applying the liquid solvent directly to the softened residue and subsequently removing the softened residue and the liquid solvent simultaneously.

3. The method of claim 1 , wherein the vapor transfer box comprises a solvent vapor chamber, and wherein solvent vapors from the solvent in the absorbent pad concentrate within the solvent vapor chamber.

4. The method according to claim 1 , wherein the liquid solvent is selected from the group consisting of ethyl-acetate, N-methyl pyrrolidinone, acetone, dimethyl adipate, dimethyl glutarate, dimethyl succinate, 1-ethyl-2-pyrrolidinone, d-limonene, and methyl isobutyl carbinol.

5. The method of claim 1 , wherein the vapor transfer box comprises a plurality of individual compartments, and wherein each individual compartment includes an absorbent pad.

6. The method of claim 1 , after the step of applying a liquid solvent to the absorbent pad, further comprising; the step of positioning a lid on the vapor transfer box to concentrate the solvent vapors within the vapor transfer box.

7. The method of claim 1 , wherein the lacquer based residue is fingernail polish.

8. The method of claim 1 , wherein stabilizers, attached to a base of the vapor transfer box, firmly position the vapor transfer box over the textile surface and lacquer based residue.

9. The method of claim 2 , wherein the liquid solvent is removed with a suction device.

10. The method of claim 3 , after the step of applying a liquid solvent, further comprising, the step of evacuating ambient air in the solvent vapor chamber through at least one hole in the solvent vapor chamber.

11. The method of claim 3 , wherein the absorbent pad comprises a plurality of smaller absorbent pads individually situated into partitioned compartments within the vapor transfer box.

12. The method of claim 2 , wherein the liquid solvent is removed by blotting the softened residue with an absorbent material.

13. The method of claim 10 , wherein the step of evacuating ambient air in the solvent vapor chamber through at least one hole in the solvent vapor chamber is accomplished by displacement of ambient air by said solvent vapors.

14. A method for softening lacquer based residue from a textile surface, including the steps of:

applying N-methyl pyrrolidinone liquid solvent to an absorbent material preventing said N-methyl pyrrolidinone liquid solvent from passing through the absorbent material and directly onto the textile surface;

placing the absorbent material over the textile surface having the lacquer based residue;

allowing N-methyl pyrrolidinone vapors from said liquid solvent to soften at least a portion of the lacquer based residue;

removing the absorbent material from the textile surface when the at least one portion of the lacquer based residue has sufficiently softened for removal; and

removing the lacquer based residue from the textile surface.

15. The method according to claim 14 , wherein the step of removing the lacquer based residue further comprises the step of applying the N-methyl pyrrolidinone liquid solvent directly to the softened residue and subsequently removing the softened residue and the solvent simultaneously.

16. The method of claim 14 , wherein the absorbent material includes at least one solvent vapor chamber positioned over the lacquer based residue, and wherein N-methyl pyrrolidinone vapors concentrate within the solvent vapor chamber to contact and soften the lacquer based residue.

17. The method of claim 14 , wherein the lacquer based residue is fingernail polish.

18. A method for softening lacquer based residue from a textile surface, including the steps of:

applying a liquid solvent selected from the group consisting of ethyl-acetate, N-methyl pyrrolidinone, acetone, dimethyl adipate, dirnethyl glutarate, dimethyl succinate, 1-ethyl-2-pyrrolidinone, d-limonene, and methyl isobutyl carbinol to an absorbent material preventing said liquid solvent from passing through the absorbent material and directly onto the textile surface;

placing the absorbent material over the textile surface having the lacquer based residue;

allowing solvent vapors from said liquid solvent to soften at least a portion of the lacquer based residue;

removing the absorbent material from the textile surface when the at least one portion of the lacquer based residue has sufficiently softened for removal; and

removing the lacquer based residue from the textile surface.
