BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall covering material such as wallpaper having excellent antifouling properties.

[0002]

2. Description of the Related Art Conventional wall coverings are generally composed of a surface material, an adhesive layer and a backing paper. Most of the surface material is made of a polyvinyl chloride sheet. Printed and embossed. In many cases, as a material having a higher quality, a material made of a woven fabric, a knitted fabric, or a nonwoven fabric is preferred, and a wall covering material mainly made of rayon fabric is used.

[0003]

[Problems to be Solved by the Invention] However, those using a fiber sheet as a surface material are liable to be stained on the surface and cannot be easily wiped off as compared with a vinyl chloride sheet, so that handling is inconvenient. Careful work is required, workability at the time of construction is poor, and it is difficult to maintain good appearance after construction for the same reason.
Furthermore, when the surface material is thin, an adhesive problem for integrating with the backing material penetrates, and the surface material has a sticky feel, and appearance problems such as a change in hue depending on the degree of penetration are caused. An object of the present invention is to solve the above-mentioned conventional disadvantages and to provide a practical wall covering material having antifouling performance.

[0004]

That is, the present invention is a wall covering material in which an adhesive layer and a backing paper are integrated with a surface fiber sheet made of a hydrophobic fiber treated with a fluorine-based processing agent. A wall covering material characterized in that a fluorine-based processing agent is attached to both surfaces of the surface fiber sheet.

In the present invention, hydrophobic fibers are used as the fibers used for the surface fiber sheet. For example, polyester fibers are preferably used. The fluorine-based processing agent applied to the fiber sheet is generally a fluorine-based resin having a fluorocarbon chain, which contains a crosslinkable monomer component in a molecular chain, and further has a crosslinking agent added to the resin. It is usually applied to the fibers as an emulsion, crosslinked by heating and fixed to the fibers.

As a method of applying a fluorine-based processing agent to a fiber sheet, there is a method of immersing a raw material fiber in a processing agent emulsion, a method of immersing a woven fabric, a knitted fabric, a nonwoven fabric, etc. in a processing agent emulsion. Is not limited to these methods. However, when the processing agent is also applied to the fiber sheet surface (back surface) facing the adhesive layer, the adhesive is less likely to penetrate into the fiber sheet surface, so that the dipping method is more preferable. In the case of the dipping method, the fluorine treatment may be performed simultaneously with the dyeing treatment.

[0007] The backing paper is integrated with the topsheet in order to impart handleability during construction and packaging and form stability to the wall covering material. Generally, paper which has been subjected to a flame retardant treatment is used. You. This integration is performed by bonding, and a vinyl acetate-based or acrylic vinyl acetate-based adhesive is used as the adhesive. The wall covering of the present invention can further perform a flame retardant treatment on the fiber sheet on the surface. Processing can be performed simultaneously.

FIG. 1 is a schematic cross-sectional view of the wall covering material of the present invention, wherein 1 is a fiber sheet treated with a fluorine-based processing agent, 2 is an adhesive layer, and 3 is a backing paper. The fiber sheet is integrated with the backing paper via an adhesive layer.

[0009]

[Effect of the Invention] The wall covering material of the present invention has a water-repellent and oil-repellent property due to a fluorine-based processing agent, so that there is little adhesion of dirt due to oil and moisture on the surface, and the antifouling property is exhibited for a long time.
Adhesive does not penetrate through the gaps between the fiber sheets and contaminate the wall covering, so that the surface of the fiber sheet does not become uneven or discolored, and the high quality feeling of the fiber sheet surface material is sufficiently exhibited. It is.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to embodiments, but the present invention is not limited to these embodiments. Example A textile made of polyester fiber was dyed, and the textile was immersed and cured using Asahigard AG710 (a fluorine-based processing agent) manufactured by Asahi Glass Co., Ltd. to obtain a surface fiber sheet. A flame retardant backing paper was bonded and integrated on the back surface of this sheet using a vinyl acetate adhesive, and a phosphorus-based flame retardant was applied to the top sheet to form a wall covering. The obtained wall covering material was examined for water repellency by the Dupont method and oil repellency by the AATCC118 method. As a result, the initial performance was 8 with water repellency.
Grade, oil repellency, grade 6 and fade irradiation (63 ° C, 40
After the time), the water repellency was class 9 or higher, and the oil repellency was class 6, indicating excellent water and oil repellency.
