Composition for dyeing of cellulosic fabric
View Patent ↗The composition that permits spray dyeing of a cellulosic, such as cotton, fabric or garment. The composition includes a wetter, an alkali, a reactive dye, a thickener, and water. The present compositions are made by first mixing together the wetter, reactive dye and water to form a first solution, then mixing the thickener into the first solution to form a second solution, and thereafter mixing or merging the alkali to the second solution within thirty minutes prior to spray application onto the cellulosic fabric or garment.
1. A spray composition for dyeing a cotton fabric consisting essentially of:
a wetter, wherein the wetter is a blend of one or more surfactants includes sulfuric acid disodium salt and phosphoric acid trisodium salt;
an alkali, wherein the alkali is a combination of soda ash, potassium carbonate, and phosphate;
a reactive dye;
a thickener;
water; and
the wetter, the alkali, the reactive dye and the thickener are anionic or non-ionic ingredients for application of the spray composition onto surfaces of the cotton fabric.
2. The composition of claim 1 , wherein the thickener is an acrylic acid copolymer.
3. The composition of claim 2 , wherein the acrylic acid copolymer has 2% to 3% naphthol spirits.
4. The composition of claim 2 , wherein the thickener is present in an amount between 5 g/l and 50 g/l based on the total g/l of the composition.
5. The composition of claim 1 , wherein the wetter is present in an amount between 5 g/l and 40 g/l based on the total g/l of the composition.
6. The composition of claim 1 , wherein the alkali is present in an amount between 3 g/l and 20 g/l based on the total g/l of the composition.
7. The composition of claim 1 , wherein the reactive dye is present in an amount between 10 g/l and 80 g/l based on the total g/l of the composition.
8. The composition of claim 1 , wherein the reactive dye is an azo metal complex or dioxazine.
9. The composition of claim 1 , wherein the cotton fabric forms a garment that is selected from the group consisting of a brassiere, shirt, pants, underwear, panty, sock, skirt, dress, shorts, coat, suit, scarf, glove, and a hat.
10. A spray composition for dyeing a cotton fabric comprising:
a wetter, wherein the wetter is a blend of one or more surfactants includes sulfuric acid disodium salt and phosphoric acid trisodium salt in an amount between 5 g/l and 40 g/l;
an alkali, wherein the alkali is a combination of soda ash, potassium carbonate, and phosphate in an amount between 3 g/l and 20 g/l;
a reactive dye in an amount between 10 g/l and 80 g/l;
a thickener in the amount of between 5 g/l and 50 g/l based on the total g/l of the composition;
water; and
the wetter, the alkali, the reactive dye and the thickener are anionic or nonionic ingredients for application of the spray composition onto surfaces of the cotton fabric.
11. The composition of claim 10 , further comprising a chelator in an amount between 1 g/l and 40 g/l based on the total g/l of the composition.
12. A spray composition for dyeing a cotton fabric consisting essentially of:
a wetter, wherein the wetter is a blend of one or more surfactants includes sulfuric acid disodium salt and phosphoric acid trisodium salt;
an alkali, wherein the alkali is a combination of soda ash, potassium carbonate, and phosphate;
a reactive dye;
a thickener;
a chelator;
water; and
the wetter, the alkali, the reactive dye and the thickener are anionic or non-ionic ingredients for application of the spray composition onto surfaces of the cotton fabric.
13. The composition of claim 12 , wherein the chelator is present in an amount between 1 g/l and 40 g/l based on the total g/l of the composition.
14. A spray composition for dyeing a cotton fabric consisting essentially of:
a wetter, wherein the wetter is a blend of one or more surfactants includes sulfuric acid disodium salt and phosphoric acid trisodium salt;
an alkali, wherein the alkali is a combination of soda ash, potassium carbonate, and phosphate;
a reactive dye;
a thickener;
at least one of a defoamer, an anti-reducing agent, and sodium chloride;
water; and
the wetter, the alkali, the reactive dye and the thickener are anionic or non-ionic ingredients for application of the spray composition onto surfaces of the cotton fabric.
