Abstract: A method for precisely applying a premetered amount of a composition into a textile substrate includes the steps of feeding a textile substrate into an application station, wherein the application station is desirably a reverse (indirect) rotogravure roll arrangement, applying a metered amount of a saturating solution to the textile substrate, while controlling the rate of speed of the substrate relative to the application station, monitoring the concentration of the solute in the textile substrate to assure a uniform level of saturation, desirably by use of an NIR evaluation, adjusting the application station to the extent necessary to assure uniform concentration of the solute on the textile substrate, and then drying the textile substrate.

Abstract: Textiles are treated with a polymer or copolymer of epihalohydrin and polyalkylene amine prior to ink jet printing onto the textile. A softener such as a quaternary ammonium salt may also be used, as may be a cationic binder.

Abstract: Waterfast ink jet printing onto textiles is performed by treating the textiles with a polymer or copolymer of epihalohydrin prior to the ink jet printing process. A softener such as a tetraalkylammonium salt may also be used, as may be a cationic binder.
