Abstract

The invention discloses high air permeability non-woven base wallpaper. The traditional non-woven wallpaper has the defects of insufficient flexibility, poor paper surface third dimension and lower opacity. The high air permeability non-woven base wallpaper comprises the following components in percent by mass of 20-72 percent of plant fiber, 10-40 percent of non-plant fiber, 10-30 percent of pigment, 2.5-10 percent of adhesive and 0.1-1.5 percent of chemical addition agent, wherein the mass percent of the components is 100 percent in sum; the plant fiber contains chemical wood pulp, the non-plant fiber contains chemical fiber, and the pigment contains at least one inorganic pigment or organic pigment with covering function. The non-woven wallpaper contains the long fiber, can be directly printed, and has the advantages of high air permeability, natural grains in paper surface, soft hand feel of finished paper, good processing property, better shape stability, good printing effect, rich color, clear pattern and strong three dimension.

Description

technical field [0001] The invention relates to a novel non-woven wallpaper, in particular to a non-woven wallpaper containing long fibers, high air permeability and capable of direct printing. Background technique [0002] Wallpaper (Wallcoverings or Wallpaper) is a widely used indoor wall decoration material, with rich colors, strong texture, rich patterns, noble, elegant and superior decorative effects, and more and more uses. [0003] Traditional wallpaper is a wall decoration material made of wallpaper base paper, which is coated or calendered, printed, embossed, or foamed in various forms. Since this kind of wallpaper is mainly based on wood pulp fiber base paper, it has disadvantages such as poor strength during processing or use, easy deformation and shrinkage with changes in environmental conditions, especially humidity, and weak water resistance and cleaning resistance. The entire manufacturing process has many links and consumes a lot of energy. [0004] Non-wov...
