Abstract
A method of making a composition for spray application onto surfaces of a cotton fabric includes mixing together a wetter, a reactive dye and water to form a first solution, adding a thickener into the first solution for between about five minutes and sixty minutes to form a partial composition, and adding an alkali with the partial composition to complete the composition.
