Per Marcia Kinter's request let me provide you with a little information about fiber reactive dyes and how they are screen printed.

Fiber reactive dyes are a water-based ink set and are screen printed as well as digitally printed onto a variety of white and buff colored natural fabrics - cotton, silk, hemp etc. The dyes are printed directly onto the fabrics, much like water-based screen printing. The dyes will remain water soluble in the fabric until they have been set via a steam process where the dyes react with the heat and surround the individual fibers of the fabric. It is more of a mechanical bond as opposed to a chemical bond as performed with sublimation dye. The fabric is typically printed on the roll and the entire roll is placed in a special steam cylinder where the entire roll is subjected to steam for a specified amount of time and temperature. The result is a very rich and permanent dyeing of the entire roll.

These are the basics of the process but much more information from the uses, to chemical safety issues have been noted in the following links. I hope this information will be of Assistance to you!

Regards,
John Coburn
