Formulating high opacity waterbased printing inks

Posted on Wed, 22 Sep 2004 at 5:17



Hello

I am a hobbiest/chemist/artist and trying to make my own textile printing inks. This works quite well for inks used for light textile materials, but it seems to be a problem to achieve high opacity on darker textiles. Of course it is possible to raise pigment content, but even than opacity isn't satisfying. The hardest problems are encounterd with white. I use TiO2 as the pigment, but for a high opacity I need about 15% TiO2 and this results in rheology problems. Is there anyone who has experience with formulating textile ink?
Please le me know
