WALLCOVERING SUBSTRATE FORMED OF TEXTURED, CONTINUOUS, MULTI-FILAMENT YARNS HAVING HYDROPHILIC CHARACTERISTICS Abstract of the Disclosure A textured, continuous, multi-filament polyester yarn has an ethoxylated alkyl aryl alcohol based sur- factant incorporated into the interfilamentary struc- ture thereof either during the texturizing process or after the yarn has been made into a gauze-like fabric substrate. The ethoxylated alkyl aryl alcohol based surfactant is characterized in that it is water disper- sible and water insoluble; has an HLB scale in the range of 7-10; is compatible with conventional wallpaper glues, is of a viscosity in the range of 50-100 SUS depending on the yarn denier; and has a smoke point greater than 350°F. The yarn so treated is formed into a gauze fabric substrate and affixed to the rear surface of a sheet material such as a vinyl wallcovering. When the glue is applied to the sheet material the surfactant treatment alters the normally hydrophobic characteristics exhibited by the textured polyester yarn so that the characteristics actually become hydrophilic. Because of the hydrophilic charac- teristics glue is accepted into and held within the interfilamentary structure of the yarn until the sheet material is affixed to the wall or other surface, thereby bonding the substrate thereto.
