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.
