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
The present invention relates to a kind of novel nonwoven wallpaper, especially relate to the nonwoven wallpaper that contains long fiber, highly-breathable, can directly print.
Background technology
Wallpaper (Wallcoverings or Wallpaper) is a kind of widely used indoor wall ornament materials, and with rich color, skin texture texture is strong, rich patterns, and the decorative effect noble quality is elegant and superior, purposes is more and more wider.
Traditional wallpaper is to be base material with the hanging raw stock, through various forms of coatings or calendering, printing, cotton ginning, or foaming and a kind of body of wall art work of processing.This type wallpaper is owing to be basic material with the wood pulp fibre body paper mainly; Therefore processing or use exist intensity relatively poor, easily with environmental condition the deform shortcoming such as indifferent of contraction, water-fast and anti-cleaning of the variation of humidity particularly; And the whole manufacturing process link is more, and energy consumption is bigger.
The nonwoven wallpaper is the novel wall surface ornament materials that grew up in recent years; Have rich color, clear patterns, the decorative effect noble quality etc. except that the same with traditional wallpaper; Therefore advantages such as also having the paper strength height, be not easy distortion, soft, paper shows the fiber natural grain especially, third dimension is strong, can directly print more and more receives the welcome in market.
