Claims12
A method for dyeing a hydrophobic fiber material, which comprises contacting said fiber material with a dye containing a combination of at least nine disperse dyes having different chemical structures from one another, wherein the combination comprises at least two primary-color dye compositions selected from the primary colors yellow, red, and blue, each of said selected primary-color dye compositions comprising at least one disperse dye.
A method for dyeing a hydrophobic fiber material, which comprises contacting said fiber material with a dye bath containing a combination of at least nine disperse dyes having different chemical structures from one another, wherein the combination comprises yellow, red, and blue primary-color dye compositions, which compositions comprise at least three yellow, three red, and three blue disperse dyes, respectively.
A dye composition comprising at least nine disperse dyes having different chemical structures from one another, wherein the composition comprises at least two primary-color dye compositions selected from yellow, red, and blue, each of said selected primary-color dye compositions comprising at least one disperse dye.
A method for dyeing a hydrophobic fiber material, which comprises contacting said fiber material with a dye bath containing a combination of at least nine disperse dyes having different chemical structures from one another, wherein the combination comprises at least one yellow, one red, and one blue disperse dye.
