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 water-based solution of an alkali metal hydroxide and an alkali metal silicate. Preferably the composition is an aqueous mixture of potassium hydroxide and sodium silicate. In the most preferred embodiment the composition includes 35 wt % potassium hydroxide at a 45 wt % concentration, 25 wt % sodium silicate at 50.degree. Baume, 5 wt % of a borate, and the balance water. The resulting solution has a high enough pH to achieve reaction between the dye and fiber but is sufficiently buffered to achieve this reaction slowly so that the fiber reactive dyes fix in a level, uniform fashion.
