Fabric wallpaper and its manufacturing method

A manufacturing method of a fabric wallpaper, the method comprising:

• obtaining a synthetic fibrous yarn in which an outer surface of a core is coated with a flame retardant resin layer;
• obtaining a fabric by a warp and a weft of the synthetic fibrous yarn;
• obtaining a processed fabric, wherein the fabric is passed through between a pressurized roller and a heating roller, and the resin layer of the synthetic fibrous yarn positioned on a reverse side of the fabric is partially melted by the heating roller to form a flat surface;
• and
• obtaining the fabric wallpaper, wherein the processed fabric and a release paper to which an adhesive agent is applied are passed through between a pair of pressurized rollers to attach the flat surface of the processed fabric and the adhesive agent applied to the release paper to each other, such that as being passed through the pair of pressurized rollers, the processed fabric, the adhesive agent, and the release paper are attached.
