Problems solved by technology

[0003] However, most of the wallpaper materials currently on the market are paper materials, which have low strength and poor waterproof effect, and cannot be made into wide-width materials.
The net height of common houses in Chinese families is 2.6-3.2m. Due to the narrow width of wallpaper materials on the market, there will be seams when they are pasted and used, and the seams are prone to warping, which will not only affect the appearance, but also The seams do not protect the wall
[0004] In addition, the seamless wall covering materials currently on the market are mainly composed of woven fabrics and non-woven fabrics. Most of them are made of fabrics and spunlace non-woven fabrics. requirements, but the water resistance of this type of material is average, and compared with wallpaper materials, the pattern of the wall covering is single, and the color patterns are not rich.
Moreover, since the surface flatness cannot be as smooth as paper, the printing effect is also poor, so you cannot freely choose your favorite shapes and patterns
In addition, due to the heavy weight and thick thickness of the wall covering, the difficulty of construction will increase accordingly. For the unavoidable joints, the traces will be very obvious, which will affect the appearance
On the other hand, the elongation of wall covering materials made by laminating fabrics and spunlace non-woven fabrics is generally large. During pasting construction, stretching and elongation will cause deformation and elongation of the cloth surface pattern, thereby Cause pattern distribution is not neat, affect the appearance
[0005] Aiming at the problems existing in the above wall decoration materials such as wallpaper and wall coverings, product developers are also constantly exploring good solutions. For example, a wide-width digitally printed polyester wall covering is disclosed in the Chinese published patent CN104141370A. The material is pad-rolled with a waterproof finishing agent to make it have a good waterproof and oil-proof effect, but the polyester wall covering is formed of ordinary fabrics, which has great restrictions in terms of color and pattern, and the product thickness is too thick and The elongation rate is large, and the product pattern is prone to deformation during pasting construction. In addition, the material does not have excellent water pressure resistance, and there is a certain bottleneck in the protection of the wall.
[0006] Another example is the Chinese patent CN108505216A which discloses a production method of polyester filament spunbond non-woven fabric. Although this patent solves the problem of product strength, the material has poor surface flatness due to the needle-punched reinforcement method. It does not have a good printing effect, and because there is no processing such as compounding, the concealment of the material is also poor

Abstract

The invention discloses a non-woven material for wall decoration. The material comprises a polyester filament non-woven fabric base material layer and a coating layer on at least one surface of the base material layer; the surface flatness of the material is 1-10 [mu]m; and the effective breadth of the material is 2.8-3.1 m. The non-woven material for wall decoration has the characteristics of being good in waterproofness, vivid in printing effect and capable of being attached seamlessly.

Description
