Abstract

A method for labeling fabrics, such as fabric garments, and a heat-transfer label well-suited for use in the method. In one embodiment, the heat-transfer label includes (a) a support portion; and (b) a transfer portion, the transfer portion being positioned over the support portion for transfer of the transfer portion from the support portion to an article of fabric under conditions of heat and pressure, the transfer portion including (i) an ink design layer; (ii) a heat-activatable adhesive layer; and (iii) an RFID device.

First claim

What is claimed is:

1. A heat-transfer label suitable for labeling fabric comprising:
(a) a support portion, said support portion comprising a carrier and a release layer, with said release layer being positioned over said carrier layer; and
(b) a single transfer portion, said transfer portion being positioned over said support portion for transfer of the transfer portion from the support portion to an article of fabric under conditions of heat and pressure, said transfer portion comprising
(i) an ink design layer printed directly onto a desired area of a wax layer,
(ii) a mask layer printed over the ink design layer, as well as onto any exposed areas of the wax layer within the ink design layer and onto a surrounding area of the wax layer,
(iii) a primer layer printed over the mask layer,
(iv) an antenna printed directly onto the primer layer,
(iv) an RFID chip bonded to the antenna, and
(v) a heat-activatable adhesive layer provided over the RFID chip.

2. The heat-transfer label of claim 1 , where the mask layer has an opaquing quality to obscure from view the RFID chip and the antenna.

3. The heat-transfer label of claim 1 , where the antenna is printed with silver ink, using screen printing or flexographic printing.

4. The heat-transfer label of claim 1 , where the RFID chip is attached using anisotropic conductive paste or film.

5. The heat-transfer label of claim 1 , where the heat-activatable adhesive layer printed over the RFID chip is also over any exposed areas of the antenna and the primer layer.

6. The heat-transfer label of claim 1 , where the heat-activatable adhesive layer is additionally over a surrounding area of the wax layer.

7. The heat-transfer label of claim 1 , where the release layer is a non-wax, non-silicone release material.

8. The heat-transfer label of claim 1 , where the heat-activatable adhesive layer has a surface roughness of 10 microns or less.

9. The heat-transfer label of claim 1 , where at least one of the layers of the transfer portion includes one or both of a watermark or a marking printed with pigments.

10. The heat-transfer label of claim 9 , where the at least one of the layers comprises the ink design layer and the heat-activatable adhesive layer.

11. The heat-transfer label of claim 9 , where the pigments are activatable by irradiation with light.

12. The heat-transfer label of claim 9 , where the ink design layer extends beyond a border of the RFID chip and the antenna.

13. The heat-transfer label of claim 9 , further comprising a stretch layer printed onto a desired area of the wax layer.

14. The heat-transfer label of claim 9 , where the heat-activatable adhesive layer extends beyond borders of the ink design layer.

15. The heat-transfer label of claim 9 , further comprising a pressure-sensitive adhesive printed over the RFID chip and the antenna.

16. The heat-transfer label of claim 9 , where the antenna is printed with water-soluble ink.
