Abstract

This utility model discloses a sponge with good resilience, comprising a sponge base layer, a rebound material layer, a sponge interlayer, a mesh layer, a sponge surface layer, and a protective layer. The sponge base layer, rebound material layer, sponge interlayer, sponge surface layer, and protective layer are bonded together in sequence from bottom to top, and a mesh layer is provided between the sponge interlayer and the sponge surface layer. The rebound material layer has a wavy structure, and the upper surface of the rebound material layer is adapted to the lower surface of the sponge interlayer. The wavy structure increases the contact area between the rebound material layer and adjacent sponge layers, which can better disperse and absorb external forces.

Description

Technical Field

[0001] This utility model relates to the field of sponge technology, and in particular to a sponge with good resilience. Background Technology

[0002] The resilience of a sponge refers to its ability to return to its original shape after being compressed by external force. It is one of the important indicators for measuring the quality of a sponge. High-resilience sponges are often used in furniture such as sofas and mattresses, providing good comfort and support.

[0003] Chinese Patent Publication No. CN209580734U discloses a novel high-resilience sponge, comprising a tensile layer, a sound-insulating layer laminated on top of the tensile layer, a heat-insulating layer laminated on top of the sound-insulating layer, a high-resilience layer laminated on top of the heat-insulating layer, and absorbent layers laminated on the top of the high-resilience layer and the bottom of the tensile layer. This novel high-resilience sponge, by incorporating a high-resilience layer made of TPE, possesses excellent high-resilience performance, breathability, and a high compression load ratio. Under pressure, it generates different support forces under different deformation states, exhibiting good dynamic fatigue resistance. Therefore, mattresses made from this novel high-resilience sponge offer high comfort.

[0004] The above-mentioned technology improves resilience by adding a TPE material layer to the sponge. However, when the sponge is subjected to force, local pressure concentration affects the overall support effect. Furthermore, excessive collapse of the sponge will affect its durability and support. Therefore, this utility model discloses a sponge with good resilience to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following solution to the above technical problems: a sponge with good resilience, comprising a sponge base layer, a resilient material layer, a sponge interlayer, a mesh layer, a sponge surface layer, and a protective layer, wherein the sponge base layer, the resilient material layer, the sponge interlayer, the sponge surface layer, and the protective layer are bonded together in sequence from bottom to top to form an integral structure, and a mesh layer is provided between the sponge interlayer and the sponge surface layer;

[0007] The elastic material layer has a wavy structure, the upper surface of the elastic material layer is adapted to the lower surface of the sponge interlayer, the lower surface of the elastic material layer is adapted to the upper surface of the sponge base layer, and the side of the sponge base layer and the sponge interlayer away from the elastic material layer are both planar structures.

[0015] This invention relates to a sponge with good resilience. The wave-shaped structure increases the contact area between the resilience material layer and the adjacent sponge layer, which can better disperse and absorb external forces. The combination of crests and troughs allows the resilience material layer to better disperse and absorb pressure when subjected to external forces, avoiding excessive compression of the sponge, reducing sponge deformation and collapse, ensuring its performance stability.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Please see Figure 1-4 This utility model provides a sponge with good resilience, including a sponge base layer 1, a resilient material layer 2, a sponge interlayer 3, a mesh layer 4, a sponge surface layer 5, and a protective layer 6;

[0025] Furthermore, the sponge base layer 1, the elastic material layer 2, the sponge interlayer 3, the sponge surface layer 5, and the protective layer 6 are bonded together in sequence from bottom to top to form an integral structure;

[0026] Specifically, through bonding, the layers can be tightly bonded together to form an integral structure. This tight bond ensures the uniform transmission of force and avoids slippage or separation between the layers, thereby improving the stability and durability of the entire sponge structure.

[0027] Furthermore, a mesh layer 4 is provided between the sponge interlayer 3 and the sponge surface layer 5;

[0028] Specifically, the mesh layer 4 can evenly distribute pressure to various parts of the sponge, thereby reducing local pressure concentration, which helps maintain the overall shape and thickness of the sponge. Even during long-term use, it can reduce the deformation and collapse of the sponge, ensure the stability of its performance, and significantly improve the sponge's breathability, support, stability, resilience and comfort.

[0029] The elastic material layer 2 has a wavy structure.

[0030] Specifically, the wave-shaped structure increases the contact area between the elastic material layer 2 and the adjacent sponge layer, which can better disperse and absorb external forces. The combination of crests and troughs allows the elastic material layer 2 to better disperse and absorb pressure when subjected to external forces, avoiding excessive compression of the sponge, reducing sponge deformation and collapse, ensuring the stability of its performance, and allowing the sponge to quickly return to its original shape when the external force applied to the sponge is removed, significantly improving the sponge's resilience.

[0031] Furthermore, the upper surface of the elastic material layer 2 is adapted to the lower surface of the sponge interlayer 3, the lower surface of the elastic material layer 2 is adapted to the upper surface of the sponge base layer 1, and the side of the sponge base layer 1 and the sponge interlayer 3 away from the elastic material layer 2 are both planar structures.

[0032] Specifically, the sponge base layer 1 and the sponge interlayer 3 have protrusions at the troughs of the rebound material layer 2, so that the side of the sponge base layer 1 and the sponge interlayer 3 facing the rebound material layer 2 also has a wave-shaped structure. This allows the sponge base layer 1 and the sponge interlayer 3 to work better with the rebound material layer 2. After the external force is removed, the protrusions can help the sponge base layer 1 and the sponge interlayer 3 to quickly return to their original shape, reduce deformation and collapse, and thus improve the resilience of the sponge.

[0033] Furthermore, the elastic material layer 2 is any one of polyurethane elastomer, polyester elastomer, or natural rubber;

[0034] Specifically, polyurethane elastomers, polyester elastomers, and natural rubber all possess properties such as high elasticity, abrasion resistance, and durability, achieving an optimal balance in terms of elasticity, breathability, softness, and durability. Combined with the wave-shaped structure design of the rebound material layer 2, the elastic properties of the material can be maximized.

[0035] Furthermore, the elastic material layer 2 is densely covered with pores;

[0036] Specifically, the presence of pores allows air to circulate freely within the rebound material layer 2, thereby improving the overall breathability of the sponge. Good breathability helps keep the sponge surface dry, reduces the growth of bacteria and mold, and provides a more hygienic environment. A sponge with good breathability can reduce the discomfort caused by heat buildup during use, improving comfort. For example, in mattresses and sofas, good breathability can reduce the stuffiness of users and provide a more comfortable experience. In addition, the pores provide more elastic space, allowing the rebound material layer 2 to better absorb and disperse pressure when subjected to force, and quickly return to its original shape after the external force is removed, significantly improving the sponge's resilience.

[0037] Furthermore, the mesh layer 4 is woven from elastic fibers, and the diameter of the elastic fibers is 0.1-0.5 mm;

[0038] Specifically, the mesh layer 4 is woven from elastic fibers. Elastic fibers are highly elastic materials that can undergo significant deformation when subjected to force and quickly return to their original shape after the external force is removed. Examples include spandex, polyester elastic fibers, or nylon elastic fibers. Smaller fiber diameters (0.1-0.5 mm) can provide better elasticity. Fine fibers can deform more flexibly when subjected to force, thereby better dispersing pressure and reducing local pressure concentration. This helps to improve the overall support and comfort of the sponge.

[0039] Furthermore, the mesh layer 4 has a pore size of 1-3 mm and an elastic modulus of 5-15 MPa;

[0040] Specifically, the pore size directly affects the breathability of the sponge. A pore size of 1-3mm allows air to circulate freely inside the sponge, thereby improving breathability. Good breathability helps keep the sponge surface dry, reduces the growth of bacteria and mold, and provides a more hygienic environment. An elastic modulus of 5-15MPa means that the mesh layer 4 has good elasticity, can deform appropriately under stress, and can quickly return to its original shape after the external force is removed. This helps to improve the overall resilience of the sponge.

[0041] Furthermore, the sponge base layer 1, the sponge interlayer 3, and the sponge surface layer 5 are all made of polyurethane sponge;

[0042] Specifically, polyurethane foam has excellent elasticity, allowing it to quickly return to its original shape after being compressed by external force. This characteristic enables the foam to provide good support and comfort during use, reducing user fatigue. Furthermore, the porous structure of polyurethane foam ensures good air circulation, thereby improving breathability. This helps keep the foam surface dry, reducing the growth of bacteria and mold, and providing a more hygienic usage environment.

[0043] Furthermore, the protective layer 6 is a composite fiber of natural cotton fiber, bamboo fiber, or polyester fiber and spandex;

[0044] Specifically, the protective layer 6 can prevent dust, stains and bacteria from entering the interior of the sponge, thereby extending the service life of the sponge and keeping its interior clean and hygienic.

[0045] Specifically, natural cotton fibers have good breathability and moisture absorption, which can absorb the sweat excreted by the human body and keep the surface of the sponge dry; bamboo fibers have natural antibacterial and anti-mite properties, which can inhibit the growth of bacteria and mites and help keep the sponge hygienic; polyester fibers have good abrasion resistance and wrinkle resistance, which can enhance the durability of the protective layer 6; and spandex gives the protective layer 6 a certain degree of elasticity, allowing the protective layer 6 to better conform to the curves of the human body, while not easily deformed during use.

[0046] Working principle: During use, the wave-shaped structure increases the contact area between the elastic material layer 2 and the adjacent sponge layer, which can better disperse and absorb external forces. The combination of crests and troughs allows the elastic material layer 2 to better disperse and absorb pressure when subjected to external forces, avoiding excessive compression of the sponge, reducing sponge deformation and collapse, and ensuring its performance stability. When the external force acting on the sponge is removed, the sponge can quickly return to its original shape, significantly improving the sponge's resilience. The mesh layer 4 can evenly distribute pressure to various parts of the sponge, thereby reducing local pressure concentration, which is conducive to maintaining the overall shape and thickness of the sponge. Even during long-term use, it can reduce sponge deformation and collapse, ensuring its performance stability, and significantly improving the sponge's breathability, support, stability, resilience, and comfort.
