Abstract
A method is provided for spray bleaching cellulosic fabrics. A bleaching composition comprises a wetter, hydrogen peroxide, a caustic, a stabilizer, an optical brightener, and water. The bleaching composition is sprayed on at least one surface of the cellulosic fabric, subjected to steam to fix the bleaching composition to the fabric, and rinsed to remove any residual bleaching composition.
