Description

Technical Field

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

[0002] Wallpaper is a common interior wall decoration. Generally, wallpaper uses a multi-layered composite structure. The side that is attached to the wall is usually non-woven fabric, while the side away from the wall is usually one or more layers of woven fabric. The layers are used individually or in combination to give the wallpaper a variety of functions. However, the multi-layered structure can affect the breathability of the wallpaper. When the breathability of the wallpaper is insufficient, it is easy for mold to grow between the wallpaper and the wall.

[0003] Therefore, a new solution is needed to address this problem. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a breathable wall covering.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a breathable wall covering, comprising a surface layer and an inner layer, wherein a sewing thread is sewn between the surface layer and the inner layer, an air guiding cavity is provided in the sewing thread, and a plurality of air holes communicating with the air guiding cavity are provided on the surface of the sewing thread, a cavity is provided between the surface layer and the inner layer, and the sewing thread forms a floating line on the side of the surface layer away from the inner layer.

[0006] The present invention is further configured such that: the suture includes a core fiber filament, a covering fiber filament, a shaped fiber filament located between the core fiber filament and the covering fiber filament, and a first fiber filament; the covering fiber filament is wound around the stranded core fiber filament, the shaped fiber filament, and the first fiber filament; the air pore is located between the covering fiber filaments; and the air guiding cavity is located between the shaped fiber filament, the first fiber filament, and the core fiber filament.

[0007] The present invention is further configured such that: the cross-section of the irregular fiber is triangular, the diameter of the first fiber is larger than the diameter of the core fiber, and the cross-section of the first fiber is C-shaped.

[0008] The present invention is further configured such that: the coated fiber filament includes a second fiber filament and a bamboo joint fiber filament, and the bamboo joint fiber filament is provided with bamboo joint structures at intervals.

[0009] The present invention is further configured such that: a sponge pad is bonded between the outer layer and the inner layer, and the stitching line is offset from the sponge pad.

[0010] The present invention is further configured such that: the core fiber filament, the shaped fiber filament, and the first fiber filament are made of polyester, and the second fiber filament and the slub fiber filament are made of nylon.

[0011] In summary, this utility model has the following beneficial effects: the sponge pad has a cavity between the surface and inner layers, and the stitching and the internal air-guiding cavity form a channel with air-guiding function. The pores distributed on the surface of the stitching allow the air-guiding cavity to communicate with the outside and the cavity respectively, ensuring the breathability of the wallpaper. The stitching forms a floating line on the surface of the wallpaper, ensuring the area of ​​the pores communicating with the outside. The polyester material has good elasticity, giving the stitching a certain degree of extensibility, and the nylon material has high durability, ensuring the service life of the stitching.

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] Example: A breathable wall covering, such as Figure 1 , Figure 2 , Figure 3 As shown, it includes an outer layer 1 and an inner layer 2. A suture is sewn between the outer layer 1 and the inner layer 2. An air guide cavity is provided inside the suture. Several air holes communicating with the air guide cavity are provided on the surface of the suture. A cavity is provided between the outer layer 1 and the inner layer 2. A floating line 3 is formed on the side of the outer layer 1 away from the inner layer 2. A sponge pad 9 is bonded between the outer layer 1 and the inner layer 2. The suture and the sponge pad 9 are staggered.

[0018] Specifically, the outer layer 1 is woven into a plain weave using a shuttle loom, and the inner layer 2 is made of needle-punched nonwoven fabric. In the longitudinal direction, the stitching lines and sponge pads 9 are alternately arranged. The sponge pads 9 create cavities between the outer layer 1 and the inner layer 2. The stitching lines and the air-guiding cavities inside them form channels that guide air. The pores distributed on the surface of the stitching lines allow the air-guiding cavities to connect with the outside world and the cavities respectively, ensuring the breathability of the wallpaper. The stitching lines form floating lines 3 on the surface of the wallpaper, ensuring the area of ​​the pores that connect with the outside world.

[0019] like Figure 2 , Figure 3As shown, the suture includes a core fiber 4, a covering fiber 5, a shaped fiber 5 located between the core fiber 4 and the covering fiber 5, and a first fiber 6. The covering fiber 5 is wrapped around the stranded core fiber 4, shaped fiber 5, and first fiber 6. The air pores are located between the covering fiber 5, and the air guiding cavity is located between the shaped fiber 5, the first fiber 6, and the core fiber 4. The cross-section of the shaped fiber 5 is triangular. The diameter of the first fiber 6 is larger than the diameter of the core fiber 4. The cross-section of the first fiber 6 is C-shaped. The covering fiber 7 includes a second fiber 7 and a bamboo-joint fiber 8. The bamboo-joint fiber 8 is provided with bamboo-joint structures at intervals. The core fiber 4, shaped fiber 5, and first fiber 6 are made of polyester, while the second fiber 7 and bamboo-joint fiber 8 are made of nylon.

[0020] Specifically, the irregularly shaped fiber 5 and the first fiber 6 are wrapped around the fiber bundle formed by the core fiber 4 in a 1:2 ratio. Two strands of the second fiber 7 and a single strand of the bamboo fiber 8 are wrapped around the array formed by the irregularly shaped fiber 5 and the first fiber 6. The core fiber 4 and the first fiber 6 support the second fiber 7 and the bamboo fiber 8. The outer diameter of the irregularly shaped fiber 5 is the same as the diameter of the first fiber 6. The cross-sectional area of ​​the irregularly shaped fiber 5 is small, which increases the cross-sectional area of ​​the air-conducting cavity and ensures the air-conducting effect of the suture. The bamboo structure on the bamboo fiber 8 is in a group of several consecutive ones, and there is a gap between two adjacent groups of bamboo structures. The bamboo structure creates a gap between the bamboo fiber 8 and the second fiber 7 to form pores. Both polyester and nylon materials are hydrophobic, which ensures that the inside of the suture is dry. Polyester material has good elasticity, which gives the suture a certain degree of extensibility. Nylon material has high durability, which ensures the service life of the suture.

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.
