Abstract
This invention is directed to treatments for dyed textile goods that will improve their fastness properties. More particularly, the invention is directed to certain fixatives that, when placed on the dyed textile, allow the dye to be permanently or substantially permanently affixed to the fabric. The dye-reactive fixative comprises a water-soluble or water-dispersible polymer or oligomer having reactive groups that react with a dye on a dyed web to affix the dye to the web.
