Abstract
The present invention provides a process for dyeing hydrophobic polymer fibers, including the step of contacting the goods with an amount of a dyeing solution effective to dye the goods, wherein the solution comprises an amount of a terpene/terpenoid solvent and a dyestuff. The present invention also provides a composition for dissolving and dispersing a dyestuff for dyeing hydrophobic polymer fibers, including effective amounts of a terpene/terpenoid solvent for dissolving the dyestuff.
Claims22
A process for dyeing polyester fibers or nylon fibers comprising the step of contacting the fibers with an amount of a dyeing solution effective to dye the fibers, wherein the solution comprises an amount of a terpene/terpenoid solvent and a hydrophobic disperse dye, wherein the terpene/terpenoid solvent completely dissolves the hydrophobic disperse dye, and wherein the terpene/terpenoid solvent is one or more terpene hydrocarbons, one or more terpenoid hydrocarbons, or a mixture of one or more terpene hydrocarbons with one or more terpenoid hydrocarbons.
A composition for dyeing polyester fibers or nylon fibers, comprising an amount of hydrophobic disperse dye effective to dye the fibers, an amount of a terpene/terpenoid solvent effective to completely dissolve the hydrophobic disperse dye, water and an amount of an emulsifier effective to disperse the terpene/terpenoid solvent and hydrophobic disperse dye in water, wherein the terpene/terpenoid solvent is one or more terpene hydrocarbons, one or more terpenoid hydrocarbons, or a mixture of one or more terpene hydrocarbons with one or more terpenoid hydrocarbons.
