Abstract

Compositions for and methods of digitally printing an ink image onto a woven textile material are provided. A base application is applied to the surface of a woven textile material, especially one comprising synthetic resin fibers prior to application of an ink image layer. The base application comprises an acrylic latex material that is formulated to be printed on with a digital ink while still wet, thereby eliminating the need for an intermediate drying cycle in between base application deposit and printing of the ink image.

First claim

What is claimed is:

1. A base application for printing an image on a woven textile material comprising:
between about 30% to about 70% by weight of an aqueous acrylic latex material;
between about 2.5% to about 20% by weight of one or more acrylic resin dispersions;
between about 5% to about 20% by weight of one or more coalescing agents; and
between about 0 to about 40% by weight of a pigment dispersion,
said one or more acrylic resins are separate from said latex material,
wherein said acrylic latex material is characterized by a minimum film-forming temperature that ranges from −10° C. to 50° C.

2. The base application of claim 1 , formulated for use using an inkjet print head.

3. The base application according to claim 1 , formulated for use using one or more nozzles configured to generate a spray of fine droplets of said base application.

4. The base application of claim 1 , further comprising at least one of a viscosity control agent, said pigment, and a binder.

5. The base application of claim 1 , further comprising one or more aziridine compounds.

6. The base application of claim 5 , comprising a first part including said aqueous acrylic latex material, and a second part including said one or more aziridine compounds.

7. The base application of claim 1 , further comprising an enzyme.

8. The base application of claim 1 , having a total water content that ranges from about 15% to about 75% by weight.

9. The base application of claim 4 , further comprising a binder at a concentration that ranges from about 0.01% to about 5% by weight.

10. The base application of claim 9 , wherein said binder comprises triethanolamine.

11. The base application of claim 1 , being inkjettable and having a viscosity that ranges from about 8 cp to about 60 cp.

12. The base application of claim 1 , wherein said coalescing agent comprises polyethylene glycol.
