Jacquard makes a line called Fabrisign for pigment that does not require steam setting and is wateproof (at least with HP inks), but not "washable". They also make a line for dyes that are steam set and supposed to be fully washable called ProCoat. I've tried Indian and Chinese Dupion, Habotai, and Crepe de Chine silks, with variable results. I still haven't gotten particularly saturated colors, and have built my own profiles with HP APS. For images that don't require screamingly bright colors, the results are quite pleasing. I'm currently printing on Lycra for some swimsuit prototypes, and the colors are much better on that. The best prices for Jacquard fabrics are not direct from them, but from Dharma Trading, who ironically drop ships direct from Jacquard. Their 6' x 42' sample rolls for $26 are a relatively painless way to experiment, and they also have swatchbooks that are available.
