Description

[Detailed Description of the Invention] This invention relates to a woven wallpaper having a structure in which the front side is made of woven fabric and is lined with a substrate made of paper.

FIG. 1 shows the cross-sectional structure of a conventional woven wallpaper. As shown in this drawing, the conventional woven wallpaper is fabric 1
has a structure in which it is bonded to a base 2 made of paper with an adhesive 3. As the adhesive 3, a vinyl acetate adhesive, an acrylic resin adhesive, or the like is used. Such wallpaper is cut into a predetermined size or shape, and adhesive is applied to the entire surface of the base 2.
It is pasted on a predetermined wall surface. However, conventional woven wallpapers have the following drawbacks.

This conventional product is simply a fabric 1 bonded to a base 2 using an adhesive. Therefore, when cutting this wallpaper with a cutter or scissors, since this wallpaper mainly consists of the fabric 1, there is a drawback that the cutting operation is relatively difficult, similar to when cutting fabric. Ta. Also,
As clearly seen in FIG. 1, the fabric 1 has unevenness and is bonded to the flat base 2, so the adhesive 3 adheres only to a portion of the fabric 1, that is, to the convex portions. I'll end up not doing it. For this reason, the fabric 1
The area that directly contributes to adhesion is small relative to the total area of the fabric, and the adhesive strength is poor.
There will also be a portion that is not bonded to the base 2. Therefore, in the edge part of wallpaper, such as the part where two wallpapers are butted together,
There was also a drawback that the threads of fabric 1 frayed, making the finished appearance ugly. Furthermore, when applying this wallpaper to a suitable wall surface, an adhesive is used, and this adhesive is usually water-based. Therefore, since the base body 2 is made of paper, the paper swells and stretches, and conversely, the fabric 1 shrinks when it absorbs water, causing the entire wallpaper to curl into a rolled-up shape. This makes the work of pasting wallpaper on the wall inefficient.

Therefore, the main objective of this invention is to provide a textile wallpaper that can advantageously eliminate the above-mentioned conventional drawbacks.

In summary, this invention is a woven wallpaper that has a woven fabric as the front side and is lined with a substrate made of paper, in which the woven fabric and the substrate are bonded via a foam adhesive layer, and the foam adhesive layer is The material is a textile wallpaper characterized by penetrating into the interior of the textile to such an extent that both the warp and weft threads of the textile are partially covered from the surrounding area.

Other objects and features of this invention will become clearer from the detailed description given below with reference to the drawings.

FIG. 2 shows a cross-sectional structure of an embodiment of this invention. As is clear from the comparison with FIG. 1, the woven wallpaper shown in FIG. have The foamed adhesive 4 is obtained by adding a foaming agent to a conventionally known adhesive such as vinyl acetate, vinyl chloride, or acrylic resin. Such blowing agents are generally known as chemicals that change resins into a cellular structure in addition to plastics and rubbers, and generate inert gas when heated. Therefore, in a preferred embodiment, an adhesive and a foaming agent are mixed in advance and heated with a heating roller or the like to foam the adhesive and cure the adhesive at the same time. Note that depending on the adhesive curing temperature or time, the adhesive curing step may be performed after the foaming step. The resin composition in which the adhesive and the foaming agent are mixed as described above is first applied to the base 2.
It is applied to the top as evenly as possible in thickness. Then, the fabric 1 is pasted thereon, and then the adhesive is foamed and cured. As a result, a woven wallpaper having a structure as shown in FIG. 2 is obtained. Here, if we focus on the foam adhesive 4, the foam adhesive 4 has penetrated into the inside of the fabric 1 to the extent that both the warp and weft of the fabric are partially covered with the foam adhesive 4. I know that there is. That is, in FIG. 2, the threads constituting the fabric 1 are shown, but if the warp is the thread that extends in the transverse direction, then The threads that extend are the weft threads. In this connection, the warp threads are partially surrounded by foam adhesive 4, as is clearly shown in FIG. Although not visible in the cross section shown in FIG. 2, the valleys of the weft yarns are brought to almost the same depth as the valleys of the warp yarns. As a result, it is partially covered by the surrounding area.

Thus, according to this invention, all of the conventional drawbacks mentioned above are eliminated. That is, according to this invention, since the foamed resin layer is present between the fabric and the substrate, the wallpaper itself can have an appropriate texture, and therefore can be easily cut with a cutter or the like. In addition, the foamed adhesive penetrates into the interior of the fabric and adheres at multiple locations to partially cover both the warp and weft of the fabric, so it has excellent adhesive strength, especially for wallpaper. There is no fraying of the threads at the edge portions of the wallpaper, and for example, the part where two pieces of wallpaper meet can always be finished well. In addition, when the adhesive is foamed, it closes the mesh of the fabric, so even if a coarse fabric is used, excellent hiding properties can be obtained, and the foamed adhesive Since it does not reach the front side of the fabric, it does not affect the texture of the fabric itself. In addition, the foamed adhesive layer increases the thickness of the wallpaper, so even when a water-based adhesive is applied to the substrate, there is almost no curling, and therefore,
The work of pasting on walls can be done efficiently. In addition, the presence of the foamed adhesive layer increases the heat insulation effect, which is expected to be effective from an energy saving perspective.
Furthermore, it is possible to create a sense of volume and increase the product value. In particular, when the yarn constituting the fabric is a spun yarn, the foaming adhesive also penetrates between the fibers included in the spun yarn, making it possible to further increase the volume of the fabric. Furthermore, the presence of the foamed adhesive layer provides dimensional stability of the wallpaper and the formation of gaps in the abutment areas after application is advantageously prevented.
