Method for manufacturing high-breathability non-woven wallpaper body paper and product

The invention discloses a method for manufacturing high-breathability non-woven wallpaper body paper and a product. The existing non-woven wallpaper has the disadvantages that the hand feel thereof is not soft enough, the principal plane stereoscopic impression is not strong and the opacity degree is low. The method of the invention comprises the following steps: beating plant fiber containing chemical wood pulp until the beating degree is 20-30OSR, and mixing with non-plant fiber containing chemical fiber; adding chemical addition agent into the mixed fiber; manufacturing the mixed fiber containing the chemical addition agent into body paper semi-finished products by utilizing a fourdrinier wire or inclined wire paper machine; mixing pigment, chemical addition agent and adhesive to form coating liquor, carrying out dip coating on the body paper semi-finished products inside or outside the machine; and drying and finishing the body paper subject to dip coating, and rolling the body paper to form finished paper of body paper, thus obtaining non-woven wallpaper which contains continuous fiber, has high breathability, and can be directly printed. The principal plane has natural lines; and the finished paper has the advantages of soft hand feel, good processability, excellent shape stability, rich color, distinct image and strong stereoscopic impression.
