Abstract

The whitening effect of a fluorescent dye applied from organic solvents to white wool was investigated. Optimum conditions for applying C. I. Fluorescent Brightening Agent #68 from perchlorethylene and Stoddard solvent at room temperature were developed. Visual evaluation in daylight and under ultraviolet light showed a marked improvement in whiteness after application of the dye to white wool fabrics. The fastness of the dye to conditions encountered during use was found to be satisfactory.
