Abstract

The present teachings include a process, system and article for forming a printed image on a textile. In some embodiments, the process includes coating the textile with a layer of polydiallyldimethyl ammonium chloride cationic polymer and coating the textile with the layer of polydiallyldimethyl ammonium chloride cationic polymer with a layer of poly-4-styrene sulfonate anionic polymer. The process can further include applying an ink composition to the textile having the layer of polydiallyldimethyl ammonium chloride cationic polymer layer and the layer of poly-4-styrene sulfonate anionic polymer, forming an image.

First claim

What is claimed is:

1. A printed article, comprising:
a woven fabric having a first layer of polydiallyldimethyl ammonium chloride cationic polymer and a second layer of poly-4-styrene sulfonate anionic polymer coated on the woven fabric, wherein the first layer contacts all portions of the woven fabric, wherein the second layer contacts all portions of the first layer; and
a cured ink composition on the woven fabric.

2. The article of claim 1 , wherein an uncured ink composition comprising water, a humectant, a water-soluble polymer, a surfactant and a colorant is disposed on the woven fabric and cured.

3. The article of claim 1 , wherein the woven fabric is selected from the group consisting of: wool, silk, cotton, linen, hemp, ramie, jute, acetate, acrylic, latex, nylon, polyester, rayon, viscose and spandex.

4. The article of claim 1 , wherein a combined thickness of the first layer and second layer is from 1.0 microns to about 300 microns.

5. The article of claim 1 , wherein the poly-4-styrene sulfonate anionic polymer has a molecular weight of from about 75,000 to about 200,000.

6. The article of claim 1 , wherein the polydiallyldimethyl ammonium chloride cationic polymer has a molecular weight of from about 100,000 to about 500,000.

7. A printed article, comprising:
a woven fabric having a first layer of poly-4-styrene sulfonate anionic polymer and a second layer of polydiallyldimethyl ammonium chloride cationic polymer coated on the woven fabric, wherein the first layer contacts all portions of the woven fabric, wherein the second layer contacts all portions of the first layer; and
a cured ink composition on the woven fabric.

8. The article of claim 7 , wherein an uncured ink composition comprising water, a humectant, a water-soluble polymer, a surfactant and a colorant is disposed on the woven fabric and cured.

9. The article of claim 7 , wherein the woven fabric is selected from the group consisting of: wool, silk, cotton, linen, hemp, ramie, jute, acetate, acrylic, latex, nylon, polyester, rayon, viscose and spandex.

10. The article of claim 7 , wherein a combined thickness of the first layer and second layer is from 1.0 microns to about 300 microns.

11. The article of claim 7 , wherein the poly-4-styrene sulfonate anionic polymer has a molecular weight of from about 75,000 to about 200,000.

12. The article of claim 7 , wherein the polydiallyldimethyl ammonium chloride cationic polymer has a molecular weight of from about 100,000 to about 500,000.
