- 6. The aqueous solution as claimed in claim 2, wherein said ratio of (A) to (B) is in a molar ratio of 1:1.2 to 1:0.7 and wherein the solution is alkaline form.
- 7. The aqueous solution as claimed in claim 2, wherein 10 to 40% of the sodium hydroxide is replaced with potassium hydroxide.
- 8. A process for dyeing cellulosic textile materials, which comprises mixing the aqueous solution as claimed in claim 7 in an alkaline form with an aqueous solution of one or more fiber-reactive dyes to form a resulting alkaline dyeing liquor, impregnating the resulting alkaline dyeing liquor to the cellulosic textile material and fixing the fiber-reactive dye or dyes by means of a dyeing and fixing process selected from the group consisting of pad-cold batch, a pad-dry-pad, steam pad-dry-thermofix, pad-steam, thermosol/pad-steam and pad/air-steam.
- 9. A process for dyeing cellulosic textile materials, which comprises mixing the aqueous solution as claimed in claim 8 in an alkaline form with an aqueous solution of one or more fiber-reactive dyes to form a resulting alkaline dyeing liquor, impregnating the resulting alkaline dyeing liquor to the cellulosic textile material and fixing the fiber-reactive dye or dyes by means of a dyeing and fixing process selected from the group consisting of pad-cold batch, a pad-dry-pad, steam pad-dry-thermofix, pad-steam, thermosol/pad-steam and a pad/air-steam.
- 10. The process as claimed in claim 8, wherein the process is a pad-cold batch, pad-dry-pad steam and pad/air-steam process.
- 11. The process as claimed in claim 9, wherein the process is a pad-cold batch, pad-dry-pad steam, and pad/air steam process.
- 12. A process for dyeing cellulosic textile materials, which comprises the steps of:mixing the aqueous solution as claimed in claim 11 in an alkaline form with an aqueous solution of one or more fiber-reactive dyes thus forming an alkaline dyeing liquor; applying said dyeing liquor on the cellulosic textile material and fixing the fiber-reactive dye or dyes by means of a dyeing and fixing process selected from the group consisting of a pad-cold batch, a pad-dry-pad steam, a pad/air-steam, a pad-dry-thermofix, a pad-steam and a thermosol/pad-steam.
- 13. A process for dyeing cellulosic textile materials, which comprises the steps of:mixing the aqueous solution as claimed in claim 12 in an alkaline form with an aqueous solution of one or more fiber-reactive dyes thus forming an alkaline dyeing liquor; applying said dyeing liquor on the cellulosic textile material and fixing the fiber-reactive dye or dyes by means of a dyeing and fixing process selected from the group consisting of a pad-cold batch, a pad-dry-pad steam, a pad/air-steam, a pad-dry-thermofix, a pad-steam and a thermosol/pad steam.
- 14. A process for dyeing cellulosic textile materials, which comprises mixing the aqueous alkaline formulation as claimed in claim 1 with an aqueous solution of one or more fiber-reactive dyes, impregnating the resulting alkaline dyeing liquor to the cellulosic textile material and fixing the dye or dyes.
- 15. The process of claim 14, wherein the process is a pad-cold batch, pad-dry-pad steam, pad/air steam, pad-dry-thermofix, pad-steam or thermosol/pad-steam process.
- 16. The aqueous solution as claimed in claim 2, which consists of sodium hydroxide and potassium carbonate in a molar ratio of 1:1.7 to 1:0.5.
