The polyester spanbond foamed wallpaper is produced by the pad-dry-cure method. The product has a good foam-sustaining ability, good water-resistance, and high strength, and reduces the amount of glue absorption. The polyester spanbond is impregnated with a composition containing 2-4wt% carboxymethylcellulose, 3-7wt% traganth gum, 0.05-0.2wt% polyvinyl alcohol, 0.05-0.2wt% boric acid and 89.5-80.8wt% water. And then it is coated with a foaming liquid of vinyl chloride or acryl to be foamed.
