Apparatus and method for ink jet printing on textiles
First Claim
1. A method for ink jet printing on a textile, comprising:
- depositing a pre-treat solution on said textile;
heating said textile to evaporate excess water from said pre-treat solution;
ink jet printing a pattern on said textile;
heating said textile a second time to evaporate excess water from the ink in said pattern;
depositing a binder/post-treat on said textile; and
heating said textile a third time to cure said binder/post-treat.

Abstract
An apparatus and method for ink jet printing on textiles is disclosed, wherein the steps of pre-treating, ink jet printing, and post-treating the textile takes place at the ink jet printer. A preferred method includes the steps of applying a pre-treat to the textile, evaporating excess water from the pre-treat, ink jet printing a pattern on the pre-treated textile, evaporating water from the ink in the pattern, applying a binder/post-treat to the pattern and curing the binder. The textile printing apparatus prints on an untreated textile by having a first application device to apply a pre-treat aqueous solution to the textile. A first heating element is arranged to evaporate most or all of the water from the pre-treated textile as it passes. An ink jet printer then accepts the pre-treated textile and prints the desired pattern on it. A second heating element at the output of the printer evaporates water from the ink in the pattern as the printed textile passes. A second application device applies a binder/post-treat to the printed textile after the ink evaporation. A third heating element dries and cures the binder/post-treat.
