Abstract: A liquid alkali composition for use in fiber reactive dyeing of cotton and cotton blended fabrics or the like. The liquid alkali is a solution of sodium hydroxide, potassium hydroxide, and potassium carbonate formed by reaction of CO2 with the potassium hydroxide solution, and adding sodium hydroxide to the resultant mixture. The resulting supersaturated solution has a high enough Total Alkalinity to achieve reaction between the dye, including vinyl sulfone dyes, and fiber but is sufficiently buffered to achieve this reaction slowly so that the fiber reactive dyes fix in a level, uniform fashion. Preferably the composition includes potassium carbonate, potassium citrate, and potassium polyacrylate. The citrate and polyacrylate act as dispersants in the dyeing process and also act as crystallization inhibitors in solution. The use of the carbonate compounds of the present invention in place of conventional silicates or phosphorus prevents the discharge of untreatable toxic wastewater into natural waterways.
