Abstract
Compositions are provided for spray dyeing of a cellulosic, such as cotton, fabric or garment. The compositions include a reactive dye, a wetter, an alkali, and water. The present compositions are made by first mixing the reactive dye, the wetter, and the water to form a solution, and thereafter adding the alkali to the solution.
Claims8
A method of making a composition for spray application onto surfaces of a cotton fabric, consisting of:
- mixing together a reactive dye, a wetter, and water to form a solution, the wetter being selected from the group consisting of a first surfactant, wherein the first surfactant is a blend of sulfuric acid disodium salt and phosphoric acid trisodium salt, and a second surfactant, wherein the second surfactant is sodium dioctyle sulfosuccinate;
- and adding an alkali to the solution to complete the composition at a time that allows spray application of the solution onto the surfaces of a cotton fabric before the dye hydrolyzes, the alkali being selected from the group consisting of a first combination of soda ash, potassium carbonate and phosphate, and a second combination of sodium silicate and a caustic.
A method of making a composition for spray application onto surfaces of a cotton fabric consisting of:
- mixing together a reactive dye, a wetter, water and at least one of a chelator, a dye leveling agent, a defoamer, and an anti-reducing agent, to form a solution, the wetter being selected from the group consisting of a first surfactant, wherein the first surfactant is a blend of sulfuric acid disodium salt and phosphoric acid trisodium salt, and a second surfactant, wherein the second surfactant is sodium dioctyle sulfosuccinate;
- and adding an alkali to the solution to complete the composition at a time that allows spray application of the solution onto the surfaces of a cotton fabric before the dye hydrolyzes, the alkali being selected from the group consisting of a first combination of soda ash, potassium carbonate and phosphate, and a second combination of sodium silicate and a caustic.
