Abstract

Methods for spot-dyeing a damaged area on a textile employing a selected color loss filter and utilizing at least one of a primary color dye. In one embodiment, the method can include the following: inspecting the damaged area through the selected color loss filter; determining whether a primary color is missing from the damaged area by being able to view the damaged area through the selected color loss filter to, thereby, confirm that the primary color is missing from the damaged area; and applying at least one of a primary color dye, corresponding to the selected color loss filter, to the damaged area, while viewing the damaged area through the color loss filter, until the damaged area is substantially invisible through the color loss filter.

Claims (33)

1. A method for spot-dyeing a damaged area on a textile, comprising the steps of:

inspecting the damaged area through a primary color loss filter;

determining whether a primary color is missing from the damaged area by being able to view the damaged area through the primary color loss filter to, thereby, confirm that the primary color is missing from the damaged area;

placing a white material on an undamaged area of a textile to be dyed;

viewing through the color loss filter the white material and the undamaged area of a textile;

matching a contrast between the white material and the undamaged area of a textile with a gray scale;

preparing at least one working dye solution according to a dilution rate corresponding to the match on the gray scale; and

applying at least one of a primary color dye, corresponding to the selected color loss filter, to the damaged area, while viewing the damaged area through the color loss filter, until the damaged area is substantially invisible through the color loss filter.

2. The method of claim 1 , before the inspecting step, further comprising the steps of:

rinsing the damaged area with a rinse solution;

extracting the excess rinse solution; and

treating the damaged area with a bleach neutralizing solution.

3. The method of claim 1 , wherein the damaged area is inspected through a blue loss filter, and wherein the primary color applied to the damaged area is blue; and

after the applying step, further comprising the step of removing the excess blue dye.

4. The method of claim 1 , wherein the damaged area is inspected through a red loss filter, and wherein the primary color applied to the damaged area is red; and

after the applying step, further comprising the step of removing the excess red dye.

5. The method of claim 1 , wherein the damaged area is inspected through a yellow loss filter, and wherein the primary color applied to the damaged area is yellow; and

after the applying step, further comprising the step of removing the excess yellow dye.

6. The method of claim 1 , wherein the determining step uses the selected color loss filter to view the damaged area, and determines whether the damaged area lacks a primary color is if the damaged area is visible through the selected color loss filter.

7. The method of claim 1 , after the determining step, further comprising the step of preparing a working dye solution by diluting a concentrated dye solution with water.

8. The method of claim 7 , wherein the concentrated blue dye solution contains about 0.00016 to 0.0016 grams of dye per 100 milliliters of water, the working red dye solution contains about 0.0002 to 0.002 grams of dye per 100 milliliters of water, and the yellow dye solution contains about 0.00008 to 0.0008 grams of dye per 100 milliliters of water.

9. The method of claim 8 , wherein the applying step further includes the step of applying a working dye solution containing approximately 1 milliliter of concentrated dye per 250 milliliters of water for light carpets, approximately 5 milliliters of concentrated dye per 250 milliliters of water for medium colored carpets, and approximately 10 milliliters of concentrated dye per 250 milliliters of water for dark colored carpets.

10. The method of claim 1 , wherein the viewing, matching, and preparing steps are repeated for each primary color.

11. The method of claim 1 , wherein the color loss filters are mounted in eye glasses.

12. A method for spot-dyeing a damaged area on a textile, comprising the steps of:

inspecting the damaged area through a selected color loss filter that filters according to a primary color;

determining whether the primary color is missing from the damaged area by being able to view the damaged area through the selected color loss filter to, thereby, confirm that the primary color is missing from the damaged area;

placing a white material on an undamaged area of a textile to be dyed;

viewing through the color loss filter the white material and the undamaged area of a textile;

matching a contrast between the white material and the undamaged area of a textile with a gray scale;

preparing at least one working dye solution according to a dilution rate corresponding to the match on the gray scale; and

applying at least one of a primary color dye, corresponding to the selected color loss filter, to the damaged area, while viewing the damaged area through the color loss filter, until the damaged area is substantially invisible through the color loss filter.

13. The method of claim 12 , further comprising the step of repeating the steps of inspecting, determining, placing, viewing, matching, preparing, and applying for a second primary color and for a third primary color.
