Abstract

A fabric print medium includes a fabric base substrate and two treatment compositions that are applied thereon. The first treatment composition includes, at least, film-forming polymeric compounds, and a water-soluble high-valence metal complex. The second treatment composition includes, at least, a polymeric network, poly-alkene polymeric compounds, a water-soluble high-valence metal complex and a flame retardant agent. Also disclosed herein is a method for obtaining the fabric print medium.

First claim

The invention claimed is:

1. A fabric print medium comprising a fabric base substrate and two treatment compositions that are applied to said fabric base substrate, wherein
a. a first treatment composition comprises, at least:
i. film-forming polymeric compounds,
ii. and a water-soluble high-valence metal complex;

b. and a second treatment composition comprises, at least:
i. a polymeric network,
ii. poly-alkene polymeric compounds,
iii. a water-soluble high-valence metal complex,
iv. and a flame retardant agent;

wherein the film-forming polymeric compounds, in the first treatment composition, are present in an amount representing from about 50 wt % to about 100 wt % by total weight of the first treatment composition.

2. The fabric print medium of claim 1 wherein the first treatment composition is disposed on the fabric base substrate and forms a first coating layer having a coat-weight in the range of about 0.1 to about 20 gram per square meter per side.

3. The fabric print medium of claim 1 wherein the second treatment composition is disposed on the fabric base substrate, over the coating layer formed by the first treatment composition, and forms a second coating layer having a coat-weight in the range of about 0.1 to about 40 gram per square meter per side.

4. The fabric print medium of claim 1 wherein the film-forming polymeric compounds, in the first treatment composition, are water-soluble polymers, waterborne polymeric latex or dispersed non-deformable polymer particles.

5. The fabric print medium of claim 1 wherein the polymeric network, in the second treatment composition, is formed by using self-cross linked polyurethane polymers or cross-linkable polyglycidyl or polyoxirane resins.

6. The fabric print medium of claim 1 wherein the polymeric network, in the second treatment composition, is formed by using vinyl-urethane hybrid copolymers or acrylic-urethane hybrid polymers.

7. The fabric print medium of claim 1 wherein the poly-alkene polymeric compounds, in the second treatment composition, are polytetrafluoroethylenes, polyamide or polyethylene polymer particles.

8. The fabric print medium of claim 1 wherein the poly-alkene polymeric compounds, in the second treatment composition, represent from about 0.2 to about 30 dry parts by total dry parts of the second treatment composition.

9. The fabric print medium of claim 1 wherein the flame retardant agent, in the second treatment composition, is selected from the group consisting of phosphorus-containing compounds, nitrogen-containing compounds and organophosphate compounds, alumina trihydrate and calcium carbonate.

10. The fabric print medium of claim 1 wherein the second treatment composition further comprises a non-reactive polymeric substance.

11. The fabric print medium of claim 1 wherein the second treatment composition further comprises inorganic compounds that have an average particle size in the range of about 0.05 to about 25 micrometers.

12. The fabric print medium of claim 1 wherein the water-soluble high-valence metal complex, in the first treatment composition and/or in the second treatment composition, is a water-soluble aluminum salt.

13. A printable media comprising fabric base substrate; a first coating layer, applied over the fabric base substrate, comprising polymeric latex present in an amount representing from about 50 wt % to about 100 wt % by total weight of the first coating layer; and an image receiving layer, applied over the first coating layer, that comprises a polymeric network, poly-alkene polymeric compounds, a water-soluble high-valence metal complex and a flame retardant agent.

14. A method for forming a fabric print medium comprising:
a. providing a fabric base substrate;
b. impregnating said fabric base substrate with a first treatment composition that comprises, at least, film-forming polymeric compounds and a water-soluble high-valence metal complex in order to form a first coating layer;
c. impregnating said fabric base substrate with a second treatment composition that comprises, at least, a polymeric network, poly-alkene polymeric compounds, a water-soluble high-valence metal complex and a flame retardant agent, in order to form a second coating layer;
d. drying the coating layers under heat to form a fabric print medium;
wherein the film-forming polymeric compounds, in the first treatment composition, are present in an amount representing from about 50 wt % to about 100 wt % by total weight of the first treatment composition.

15. The method of claim 14 wherein the impregnating of said fabric base substrate with the second treatment composition is accomplished via a wet-on-wet method.

16. The method of claim 14 wherein pressure is applied to said fabric substrate after the impregnating of said fabric base substrate with the second treatment composition, and the pressure is between about 10 PSI and about 100 PSI.

17. The fabric print medium of claim 1 wherein the film-forming polymeric compounds, in the first treatment composition, are dispersed non-deformable polymer particles selected from the group consisting of styrene, acrylic, styrene/acrylics, vinyl/acetate, polyacrylics, methacrylates, and combinations thereof.

18. The fabric print medium of claim 1 wherein the polymeric network comprises epoxy-functional additives.

19. The fabric print medium of claim 18 wherein the polymeric network further comprises an epoxy resin hardener selected from the group consisting of water-based polyfunctional amines, acids, acid anhydrides, phenols, alcohols, thiols, and combinations thereof.
