Description

Technical Field

[0001] This utility model relates to the field of wallpaper, and more specifically, to a multi-layer wallpaper. Background Technology

[0002] Wallpaper is a textile used to decorate walls and is one of the most common wall decoration methods. Compared with traditional wall paint, wallpaper is simpler and faster to install, and you can move in sooner after installation. Therefore, wallpaper is widely used.

[0003] Existing wallpapers need to release moisture from the wall surface in a timely manner during use to prevent mold growth. Therefore, wallpapers often have a certain degree of breathability to dissipate moisture. However, this makes it easy for external moisture to seep into the wallpaper. When the wallpaper gets wet, it is difficult to dry quickly. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-layer wallpaper.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a multi-layer wall covering, comprising a surface layer and an inner layer, wherein the surface layer is woven from hydrophobic yarns, and the inner layer is woven from a first warp yarn, a second warp yarn, and a weft yarn to form an alternating layer structure, wherein the first warp yarn is distributed on the side of the inner layer closer to the surface layer, and the second warp yarn is distributed on the side of the inner layer away from the surface layer, wherein the hydrophilicity of the first warp yarn is better than that of the second warp yarn.

[0006] The present invention is further configured such that the weft yarn includes moisture-wicking yarn and antibacterial yarn.

[0007] The present invention is further configured such that the moisture-wicking yarn and the antibacterial yarn are alternately arranged in a 1:1 ratio.

[0008] The present invention is further configured such that the weaving density of the outer layer is less than that of the inner layer.

[0009] The present invention is further configured such that the thickness of the outer layer is less than the thickness of the inner layer.

[0010] The present invention is further configured such that the hydrophobic yarn is made of twisted polyester fibers.

[0011] In summary, this invention has the following beneficial effects: a unidirectional moisture-wicking structure is formed on the inner layer towards the outer layer. Because in the alternating layer structure, the weft yarns alternately contact the first and second warp yarns, increasing the moisture-wicking speed between the first and second warp yarns, allowing the inner layer to dry quickly. The polyester fibers have good hydrophobicity, and the outer layer covering the outer side of the inner layer reduces the moisture falling from the outside onto the inner layer. The mesh structure on the outer layer also ensures that the gases on both sides of the outer layer can be exchanged, thereby expelling moisture between the outer and inner layers.

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] Example: A multi-layered wall covering, such as Figure 1 , Figure 2 As shown, it includes an outer layer 1 and an inner layer 2. The outer layer 1 is woven from hydrophobic yarns, and the inner layer 2 is woven from a first warp yarn 3, a second warp yarn 4, and weft yarns to form an alternating layer structure. The first warp yarn 3 is distributed on the side of the inner layer 2 closer to the outer layer 1, and the second warp yarn 4 is distributed on the side of the inner layer 2 away from the outer layer 1. The hydrophobicity of the first warp yarn 3 is better than that of the second warp yarn 4. The hydrophobic yarns are made of twisted polyester fibers.

[0017] Specifically, both the outer layer 1 and the inner layer 2 are woven using a woven method. The first warp yarn 3 is cotton yarn, and the second warp yarn 4 is polyester yarn. Through the alternating layer structure, the two sides of the inner layer 2 exhibit different hydrophilicities. The first yarn, which has better hydrophilicity, is concentrated on the side of the inner layer 2 closer to the outer layer 1. Therefore, a unidirectional moisture-wicking effect is formed on the inner layer 2 towards the outer layer 1. Furthermore, because the weft yarn alternately contacts the first warp yarn 3 and the second warp yarn 4 in the alternating layer structure, the moisture-wicking speed between the first warp yarn 3 and the second warp yarn 4 is increased, allowing the inner layer 2 to dry quickly. The hydrophobic yarn is made of three strands of polyester fiber twisted together. Polyester fiber has good hydrophobicity, and the outer layer 1 covering the outside of the inner layer 2 reduces the moisture falling onto the inner layer 2 from the outside. At the same time, because water vapor is more microscopic than water droplets, the mesh structure on the outer layer 1 ensures that the gas on both sides of the outer layer 1 can be exchanged, thereby expelling the water vapor between the outer layer 1 and the inner layer 2.

[0018] like Figure 1, Figure 2 As shown, the weft yarn includes moisture-wicking yarn 5 and antibacterial yarn 6, which are alternately arranged in a 1:1 ratio. The weaving density of the outer layer 1 is less than that of the inner layer 2, and the thickness of the outer layer 1 is less than that of the inner layer 2. Specifically, the moisture-wicking yarn 5 is made of twisted Y-shaped polyester fiber filaments, and the surface groove structure ensures the moisture-wicking speed of the moisture-wicking yarn 5. The antibacterial yarn 6 is made of twisted modified polyester fiber filaments. The modified polyester fiber filaments are polyester fiber filaments with silver ion masterbatch added by melt blending, which have good antibacterial properties. The alternating arrangement of the moisture-wicking yarn 5 and the antibacterial yarn 6 ensures the contact area between the antibacterial yarn 6 and other yarns, thereby ensuring the antibacterial properties of the inner layer 2. The outer layer 1 reduces the weaving density by missing padding yarns, thereby forming a mesh structure. At the same time, the thinner thickness of the outer layer 1 ensures the breathability of the outer layer 1.

[0019] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
