Abstract
Cotton fabric and cotton-blended fabric which has been sensitized by treatments with methylol phosphorus compounds and heat-dried have been subjected to a 'wet-transfer' technique which transfers a formaldehyde donor along with an aqueous ammonium hydroxide solution, thus providing an improved process for imparting flame retardance to fibrous cellulosic materials.
