Abstract

A fabric print medium containing a fabric base substrate and a primer layer composition applied to the fabric base substrate. Said primer layer composition includes at least three types of polymeric particles, at least two different fire retardant agents and a water-soluble high-valence metal complex. Also disclosed are the method for making such fabric print medium and the method for producing printed images using said material.

First claim

The invention claimed is:

1. A fabric print medium comprising:
a. a fabric base substrate;
b. a primer layer composition applied to the fabric base substrate, the primer layer composition including:
i. at least three types of polymeric particles,
ii. at least two different fire retardant agents,
iii. and a water-soluble high-valence metal complex.

2. The fabric print medium of claim 1 wherein the primer layer composition forms, on the fabric base substrate, a coating layer having a coat-weight in the range of about 0.1 to about 50 gram per square meter.

3. The fabric print medium of claim 1 wherein the fabric base substrate is woven, knitted, non-woven or tufted and comprises natural or synthetic fibers selected from the group consisting of wool, cotton, silk, rayon, thermoplastic aliphatic polymers, polyesters, polyamides, polyimides, polypropelene, polyethylene, polystyrene, polytetrafluoroethylene, fiberglass, polytrimethylene, polycarbonates, polyester terephthalate and polybutylene terephthalate.

4. The fabric print medium of claim 1 wherein the primer layer composition comprises first polymeric particles that are film forming polymers; second polymeric particles that are non-deformable particles and third polymeric particles that are poly-alkene compounds.

5. The fabric print medium of claim 1 wherein the primer layer composition comprises first polymeric particles that are polyurethane compounds, second polymeric particles that are reactive or non-reactive polymeric particles and third polymeric particles that are poly-alkene compounds.

6. The fabric print medium of claim 1 wherein, in the primer layer composition, the fire retardant agents are present in an amount representing more than 2 wt % by total weight of the fabric base substrate and of the polymeric particles.

7. The fabric print medium of claim 1 wherein, in the primer layer composition, a first fire retardant agent is in a solid state and a second fire retardant agent is in a liquid state in the ambient temperature.

8. The fabric print medium of claim 1 wherein, in the primer layer composition, the first fire retardant agents is a non-halogenated compound or an organophosphate compound and the second fire retardant is a water-soluble phosphorus-containing compound.

9. The fabric print medium of claim 1 wherein, in the primer layer composition, the water-soluble high-valence metal complex is a water-soluble compound containing a high-valence metallic ion, a water-soluble cationic high-valence metallic complex or a water-soluble cationic polymeric compounds containing high-valence metallic ion.

10. The fabric print medium of claim 1 wherein, in the primer layer composition, the water-soluble high-valence metal complex is water-soluble aluminum salts.

11. A method for forming a fabric print medium comprising:
a. providing a fabric base substrate;
b. impregnating said fabric base substrate with a primer layer composition, said composition including at least three types of polymeric particles, at least two different fire retardant agents and a water-soluble high-valence metal complex;
c. drying the fabric substrate under heat to form a fabric medium substrate.

12. The method of claim 11 wherein pressure is applied to the fabric base substrate after impregnating said fabric with the primer layer composition.

13. A printing method comprising:
a. obtaining a fabric print medium comprising a fabric substrate and a primer layer composition applied to the fabric substrate, the primer composition including at least three types of polymeric particles, at least two different fire retardant agents and a water-soluble high-valence metal complex;
b. and applying an ink composition onto said fabric print medium to form a printed image.

14. The printing method of claim 13 wherein the ink composition is applied to the fabric print medium via inkjet printing techniques.

15. The printing method of claim 13 wherein the ink composition is an ink composition containing latex components.
