Description

Technical Field

[0001] This utility model specifically relates to the field of soft-backed carpet technology, and more specifically to an environmentally friendly soft-backed carpet. Background Technology

[0002] In the carpet industry, with the continued deepening of environmental protection concepts, consumers have put forward more stringent requirements for the environmental performance, structural stability, and user experience of carpets. Existing carpets generally have the following defects: First, some carpets are produced using non-environmentally friendly materials, which easily release harmful substances such as formaldehyde and heavy metals during production or use, seriously affecting the quality of the indoor environment. Second, the layers of carpets are mostly connected by simple adhesive methods, resulting in serious instability of the connection and easy delamination after long-term use. Third, the soft backing does not adhere well to the ground, making it easy to shift during use, and the comfort underfoot needs to be improved. Fourth, the connection between the carpet surface layer and the transition layer lacks an effective positioning structure, making it easy for the layers to slide relative to each other, which greatly reduces the overall durability of the carpet. Utility Model Content

[0003] The purpose of this invention is to provide an environmentally friendly soft-backed carpet. In this device, the protruding structure at the bottom of the carpet surface layer is fixed to a groove on the upper surface of the transition layer by an adhesive layer. The carpet surface layer is T-shaped, which effectively increases the thickness at the center of the carpet surface layer and improves its wear resistance. The raised pad at the bottom of the soft backing layer effectively increases the friction between the carpet and the ground, preventing the carpet from shifting. This solves the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An environmentally friendly soft-backed carpet includes a carpet surface layer, a transition layer, and a soft backing layer. The carpet surface layer is disposed on the upper surface of the transition layer, and the edge of the carpet surface layer is flush with the edge of the transition layer. The transition layer is disposed on the upper surface of the soft backing layer, and the edge of the transition layer is flush with the edge of the soft backing layer. An adhesive layer is disposed between the carpet surface layer and the transition layer, and the adhesive layer completely covers a groove opened on the transition layer. The upper surface of the adhesive layer is adhered to the lower surface of the carpet surface layer, and the bottom of the carpet surface layer is T-shaped.

[0006] As a further technical solution of this utility model, the upper surface of the soft backing layer is provided with intersecting U-shaped grooves, the U-shaped grooves are arranged along the circumference of the soft backing layer, and the opening of the U-shaped grooves faces upward; the lower surface edge of the transition layer is provided with a part that fits with the U-shaped groove.

[0007] As a further technical solution of this utility model, a second adhesive layer is provided between the soft backing layer and the transition layer. The second adhesive layer fills the U-shaped groove and the area on the upper surface of the soft backing layer other than the U-shaped groove. The upper surface of the second adhesive layer is bonded and fixed to the lower surface of the transition layer.

[0008] As a further technical solution of this utility model, the soft backing layer has multiple convex pads integrally arranged on the side away from the U-shaped groove; the cross-section of the convex pads is semi-circular, and the multiple convex pads are distributed in an array.

[0009] As a further technical solution of this utility model, the outer periphery of the carpet surface layer, the transition layer and the soft backing layer are also wrapped with an edge strip, the inner side of which is respectively attached to the side of the carpet surface layer, the side of the transition layer and the side of the soft backing layer.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. In this utility model, the bottom of the carpet surface layer is T-shaped, which cooperates with the groove on the transition layer and the adhesive layer that completely covers the groove to form a T-shaped fitting + full-area bonding connection structure. This greatly enhances the connection between the carpet surface layer and the transition layer, and avoids relative slippage between the layers. The lower surface of the transition layer and the upper surface of the soft backing layer are connected by a double structure of U-shaped groove fitting and second adhesive layer filling and bonding. The circumferential design of the U-shaped groove allows the edge of the transition layer to fit precisely with the soft backing layer. The second adhesive layer further fills the gap and fully bonds, making the connection between the transition layer and the soft backing layer more stable. It is not easy to delaminate after long-term use, effectively extending the overall service life of the carpet.

[0012] 2. In this utility model, the convex pads on the side of the soft backing layer away from the U-shaped groove are semi-circular and arranged in an array. This increases the contact friction with the ground, effectively preventing the carpet from shifting on smooth surfaces such as tiles and wood floors, thus improving safety. Furthermore, the combination of the arc-shaped structure of the convex pads and the flexibility of the soft backing layer makes the carpet more easily conform to the minor unevenness of the ground, resulting in a smoother surface and a more comfortable feel underfoot.

[0013] 3. In this utility model, the outer edge banding strip can simultaneously adhere to the sides and edges of the carpet surface layer, transition layer, and soft backing layer, effectively preventing wear and tear or fraying at the carpet edges, protecting the structural integrity of the carpet from the outer periphery, and further extending its service life.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-6 In this embodiment of the present invention, an environmentally friendly soft-backed carpet includes a carpet surface layer 1, a transition layer 2, and a soft-backed layer 3. The carpet surface layer 1 is disposed on the upper surface of the transition layer 2, and the edge of the carpet surface layer 1 is flush with the edge of the transition layer 2. The transition layer 2 is disposed on the upper surface of the soft-backed layer 3, and the edge of the transition layer 2 is flush with the edge of the soft-backed layer 3. An adhesive layer 5 is disposed between the carpet surface layer 1 and the transition layer 2, and the adhesive layer 5 completely covers the groove 6 opened on the transition layer 2. The upper surface of the adhesive layer 5 is attached to the lower surface of the carpet surface layer 1, and the bottom of the carpet surface layer 1 is T-shaped.

[0023] The upper surface of the soft backing layer 3 is provided with intersecting U-shaped grooves 7, which are arranged along the circumference of the soft backing layer 3 and with the opening of the U-shaped grooves facing upward; the lower surface edge of the transition layer 2 is provided with a part that fits into the U-shaped grooves 7.

[0024] By adopting the above technical solution, the bottom of the carpet surface layer 1 is T-shaped, which cooperates with the groove 6 opened on the transition layer 2 and the adhesive layer 5 that completely covers the groove to form a T-shaped fitting + full-area bonding connection structure. This greatly enhances the connection between the carpet surface layer 1 and the transition layer 2, and avoids relative slippage between the layers. The lower surface of the transition layer 2 and the upper surface of the soft backing layer 3 are connected by a double structure of U-shaped groove fitting + second adhesive layer filling and bonding. The circumferential design of the U-shaped groove allows the edge of the transition layer to fit precisely with the soft backing layer. The second adhesive layer further fills the gap and fully bonds, making the connection between the transition layer 2 and the soft backing layer 3 more stable. It is not easy to delaminate after long-term use, effectively extending the overall service life of the carpet.

[0025] In this embodiment, a second adhesive layer is also provided between the soft backing layer 3 and the transition layer 2. The second adhesive layer fills the U-shaped groove 7 and the area on the upper surface of the soft backing layer 3 other than the U-shaped groove 7. The upper surface of the second adhesive layer is bonded and fixed to the lower surface of the transition layer 2.

[0026] In this embodiment, the soft backing layer 3 is integrally provided with a plurality of convex pads 4 on the side away from the U-shaped groove 7; the cross-section of the convex pads 4 is semi-circular, and the plurality of convex pads 4 are distributed in an array.

[0027] By adopting the above technical solution, the raised pads 4 on the side of the soft backing layer 3 away from the U-shaped groove 7 are semi-circular and arranged in an array. This increases the contact friction with the ground, effectively preventing the carpet from shifting on smooth surfaces such as tiles and wood floors, thus improving safety. Furthermore, the combination of the arc-shaped structure of the raised pads 4 and the flexibility of the soft backing layer makes the carpet more easily fit into the minor unevenness of the ground, resulting in a smoother surface and a more comfortable feel underfoot.

[0028] Furthermore, the outer periphery of the carpet layer 1, the transition layer 2, and the soft backing layer 3 is also wrapped with an edge banding strip, the inner side of which is respectively attached to the side of the carpet layer 1, the side of the transition layer 2, and the side of the soft backing layer 3.

[0029] By adopting the above technical solution, the outer edge banding strip can simultaneously adhere to the sides and edges of the carpet surface layer 1, transition layer 2, and soft backing layer 3, effectively preventing wear and tear and fraying at the carpet edges, protecting the structural integrity of the carpet from the outer periphery, and further extending its service life.

[0030] The working principle of this utility model is as follows: The bottom of the carpet surface layer 1 is T-shaped, which cooperates with the groove 6 opened on the transition layer 2 and the adhesive layer 5 that completely covers the groove to form a T-shaped fitting + full-area bonding connection structure, which greatly enhances the connection between the carpet surface layer 1 and the transition layer 2 and avoids relative sliding between the layers. The lower surface of the transition layer 2 and the upper surface of the soft backing layer 3 are connected by a double structure of U-shaped groove fitting + second adhesive layer filling and bonding. The circumferential design of the U-shaped groove allows the edge of the transition layer to fit precisely with the soft backing layer. The second adhesive layer further fills the gap and fully bonds, making the connection between the transition layer 2 and the soft backing layer 3 more stable. It is not easy to delaminate after long-term use, effectively extending the overall service life of the carpet.

[0031] The raised pads 4 on the side of the soft backing layer 3 away from the U-shaped groove 7 are semi-circular and arranged in an array. This increases the contact friction with the ground, effectively preventing the carpet from shifting on smooth surfaces such as tiles and wood floors, thus improving safety. Furthermore, the curved structure of the raised pads 4, combined with the flexibility of the soft backing layer, allows the carpet to better conform to minor unevenness in the ground, resulting in a smoother surface and a more comfortable feel underfoot.

[0032] The outer edge banding can simultaneously adhere to the sides and edges of the carpet surface layer 1, transition layer 2, and soft backing layer 3, effectively preventing wear and tear and fraying at the carpet edges. It protects the structural integrity of the carpet from the outer perimeter and further extends its service life.
