compositions are orange 3g red 2b and blue 4r disperse dye components are likewise well known to those skilled in the art and are water insoluble nonionic species containing one or more organic chromophore moieties disperse dyes are either provided in paste form in combination with a dispersing agent or in powder form different disperse dyes can be used in combinations to arrive at a precisely defined color choice depending on process conditions such as the use rate of each selected disperse dye component the specific dispersing agent or agents employed and the residence time of the substrate in the dyeing zone examples of suitable disperse dye compositions are disperse red 60 disperse yellow 86 and disperse violet 33 anti stain components for use in the disclosed stain blocker compositions have a component bearing an acidic moiety which associates with polymer amine end groups and protects them from staining by acidic dye stains the general category of chemicals suitable to the process of the instant invention can comprise any chemical that blocks positively charged dye sites stain blockers are available in various forms such as syntans sulfonated novolacs sulfonated aromatic aldehyde condensation products sacs and or reaction products of formaldehyde phenolics substituted phenolics thiophenolics sulfones substituted sulfones polymers or copolymers of olefins branched olefins cyclic olefins.
