New description: [New technical field] This creation is a kind of mesh structure, especially a multi-layer three-dimensional mesh structure for insoles, cushions and mattresses. [Prior Art] There are a wide variety of carcass materials for shoe lasts, seat covers and mattresses, such as foam, latex, straw, rattan 'coconut, plastic kick beads or animal fur, etc. Special function 'but the above materials have the problem of being elastic and tired after using for a period of time, so that the user can't exert the average force, so the partial pressure of the body is too large and has no supporting effect; and the foam material is easy to hide the dust field. It can harm the respiratory system, causing asthma and allergies. Even a small number of dust mites will drill into the dermal tissue through the expanding pores to lay eggs. The skin is allergic, itchy and even inflamed. For allergic constitutions and newborns, it is - Big troubles; in addition, 'foam material can not be recycled after use, it is easy to cause environmental pollution. The latex material does not discharge heat quickly, so the user often has a damp and sultry discomfort. In addition, materials such as straw, rattan, coir and plastic beads may cause roughening of the surface due to long-term wear and tear, which may be necessary to improve the material or structure of the mat. [New content] The shortcoming of the existing mat body is that the purpose of the present invention is to provide a multi-layered three-dimensional mesh structure with elasticity and a breathable effect. In order to achieve the above object, the present invention provides a multi-layered three-dimensional mesh structure, which comprises at least a composite structure, each composite structure is formed by superposing a cladding material 3 M423618 and a three-dimensional mesh structure. The material structure is formed by staggered flat weaving of a strip of thermoplastic elastomer (TPE), which is formed by hot pressing to produce a plurality of convex portions and concave portions; and a primary covering material, the secondary covering material structure and the composite structure The three-dimensional mesh structure is superimposed to form a multilayer three-dimensional mesh structure. The multi-layered three-dimensional mesh structure has elasticity and thus can be used as a cushioning material, and the three-dimensional mesh structure has a plurality of voids for air circulation, and a good ventilation effect can be achieved. Preferred thermoplastic elastomers include, but are not limited to, styrenic block copolymer (SBC), nibber-polyolefin blend, thermoplastic polyurethane (therm〇plastic polyurethane). , TPU), thermomized plastic copolyester or p〇lyether block amides (PEBA). More preferably, the thermoplastic elastomer is a thermoplastic polyester elastomer (TPEE). Preferably, the convex portion and the concave portion are spaced apart from each other. Preferably, the covering material is a breathable cloth. Preferably, the covering material and the secondary covering material or one end of the adjacent two covering materials are integrally connected to each other, and the inner side of the covering material and the secondary covering material or the adjacent two covering materials are respectively The three-dimensional mesh structure is in contact with the convex portion on both sides of the three-dimensional mesh structure, and the three-dimensional mesh structure is coated between the covering material and the secondary covering material. Preferably, the covering material comprises Nylon fiber, poly: lytic fiber, cotton or Polypropylene fiber. More preferably, the covering material is blended with any of the above components and an elastic fiber made of polyurethane (PU). M423618 Decorations are still within the scope of this creative technical solution. [Simplified illustration] Figure 1 is an exploded perspective view of the creation.
