Abstract

Provided is a treatment agent used for forming an image on fabric, containing a resin emulsion and a metal salt. A pH of the treatment agent is in a range from 5.5 to 9. The pH may be adjusted using a pH adjuster. Examples of the pH adjuster include sodium bicarbonate, potassium carbonate, calcium carbonate, sodium hydroxide, sodium carbonate, triethanolamine, and N-butyl diethanolamine.

First claim

What is claimed is:

1. A method for preventing discoloration in fabric, comprising:
a treatment step of applying, on fabric, a treatment agent, the treatment agent comprising a resin emulsion and a metal salt and having a pH of 5.5 to 9;
a compression step of compressing the treatment agent-applied area;
a heat-treatment step of heat-treating the treatment agent-applied area in a range from 160° C. to 185° C. after the treatment step;
an image printing step of printing an image on a treatment agent-applied area with an ink after the heat-treatment step; and
a heat-fixing step of heat-fixing the ink on the fabric after the image printing step, wherein
discoloration on the treatment agent-applied area in the heat-treatment step is prevented by the use of the treatment agent in the treatment step.

2. The method according to claim 1 , wherein
the treatment agent further comprises a pH adjuster, and
the pH adjuster is at least one selected from the group consisting of alkali metal hydroxides, alkali metal carbonates, hydroxides of elements in Groups 2 to 12, carbonates of elements in Groups 2 to 12, and amines.

3. The method according to claim 2 , wherein
the pH adjuster is at least one selected from the group consisting of sodium bicarbonate, potassium carbonate, calcium carbonate, sodium hydroxide, sodium carbonate, triethanolamine, and N-butyl diethanolamine.

4. The method according to claim 1 , wherein
the resin emulsion is an acrylic resin emulsion.

5. The method according to claim 1 , wherein
the metal salt is calcium nitrate.

6. The method according to claim 1 , wherein
as the ink used in the image printing step, an ink comprising a pigment is used.

7. The method according to claim 1 , wherein
the image printing step is performed by ink-jet recording.

8. The method according to claim 1 , wherein
the image printing step comprises:
a base area forming step of forming a base area on the treatment agent-applied area with a first ink; and
an image printing step of printing an image on the base area with a second ink.

9. The method according to claim 8 , wherein
a white ink is used as the first ink.

10. The method according to claim 8 , wherein
a color ink is used as the second ink.

11. The method according to claim 1 , wherein
the heat-treatment step and the compression step are performed at the same time using a hot pressing machine, and
the image printing step is performed after the heat-treatment step and the compression step.

12. The method according to claim 11 , wherein
the heat-treatment step and the compression step are performed using the hot pressing machine in the state where a sheet is placed on the treatment agent-applied area.

13. The method according to claim 12 , wherein
the heat-treatment step and the compression step are performed using the hot pressing machine in the state where a sheet with a smooth surface is placed on the treatment agent-applied area.

14. The method according to claim 12 , wherein
the heat-treatment step and the compression step are performed using the hot pressing machine in the state where a Teflon® sheet is placed on the treatment agent-applied area.
