Abstract
The present teachings include a process, system and article for forming a printed image on a textile. The process includes coating the solution of an orthosilicate to form a silica network on the textile. The process includes applying an ink composition to the textile having the silica network on the textile, forming an image.
Claims12
A method of printing an image on a textile, the method comprising:
- coating and curing the textile with a solution comprising an orthosilicate, a water miscible solvent, water and ammonium hydroxide (NH4OH), thereby creating a silica network attached to the textile, wherein the solution comprises from 70 weight percent to 85 weight percent of the water miscible solvent, from 5 weight percent to 15 weight percent water, from 10 weight percent to 20 weight percent NH4OH and from 0.1 weight percent to 2 weight percent orthosilicate;
- and
- applying an ink composition to the silica network, forming an image on the silica network.
8-16. (canceled)
A printed article, comprising:
- a fabric having a silica network on a surface of the fabric, wherein the silica network is formed by applying a solution comprising from 70 weight percent to 85 weight percent of a water miscible solvent, from 5 weight percent to 15 weight percent water, from 10 weight percent to 20 weight percent ammonium hydroxide (NH4OH) and from about 0.1 weight percent to about 2 weight percent orthosilicate to the fabric and curing the solution;
- and
- a cured ink composition disposed on the silica network on the surface of the fabric.
