[0018] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-2This utility model provides a technical solution: a thin microfiber synthetic leather for edging, comprising a synthetic leather body 1, the synthetic leather body 1 being semi-circular, with polyester fiber reinforcing layers 2 at both ends of the diameter of the synthetic leather body 1, a polyurethane reinforcing layer 3 at the top of the arc of the synthetic leather body 1, a polyester reinforcing layer 4 between the polyester fiber reinforcing layer 2 and the polyurethane reinforcing layer 3, a first cavity 5 formed by the two polyester fiber reinforcing layers 2 and the polyester reinforcing layer 4 being filled with an elastic material 6, a second cavity 7 formed by the polyester fiber reinforcing layer 2 at the top of the synthetic leather body 1, the polyurethane reinforcing layer 3 and the polyester reinforcing layer 4 being filled with a nylon polymer 8, and a third cavity 9 formed by the polyester fiber reinforcing layer 2 at the bottom of the synthetic leather body 1, the polyurethane reinforcing layer 3 and the polyester reinforcing layer 4 being filled with a pressure-resistant composite material 10.

[0020] Specifically, the polyester reinforcing layer 4 is semi-circular and is tangential to the polyurethane reinforcing layer 3. This arrangement allows the polyurethane reinforcing layer 3 to be cushioned by the force of the polyester reinforcing layer 4 when subjected to pressure, thereby further enhancing the compressive strength of the synthetic leather body 1.

[0021] Specifically, the polyester reinforcement layer 4 and the polyester fiber reinforcement layer 2 are sewn together by connecting tape 11. The connection between the polyester reinforcement layer 4 and the polyester fiber reinforcement layer 2 is made stronger by connecting tape 11. The polyester reinforcement layer 4 can also help the two polyester fiber reinforcement layers 2 to reduce the pressure they are subjected to, thereby further improving the pressure resistance of the synthetic leather body 1.

[0022] Specifically, the elastic material 6 is polyurethane foam, the nylon polymer 8 is polyamide, the compression-resistant composite material 10 is a mixture of polypropylene and glass fiber, and the polyester fiber reinforcement layer 2, polyurethane reinforcement layer 3, and polyester reinforcement layer 4 are also filled with high-density polyester material. The elastic material 6, being polyurethane foam, provides good elastic support for the first cavity 5, giving the synthetic leather better flexibility and durability during use. The use of polyamide gives the surface of the second cavity 7 good abrasion resistance and tear resistance. The filling of the mixture of polypropylene and glass fiber ensures that the third cavity 9 can still maintain its shape and is not easily deformed when subjected to heavy pressure. The high-density polyester reinforcement layer provides the necessary structural strength and stability for the entire synthetic leather.

[0023] A specific application example of this embodiment is as follows:

[0024] Thin microfiber synthetic leather is applied to the edges of athletic shoes to improve their durability and comfort. During strenuous exercise, athletic shoes are frequently subjected to forces from various directions, especially the edges, which are prone to wear and tear. The pressure on the foot is cushioned by the polyester fiber reinforcement layer 2 at the top of the synthetic leather body 1, while the ground reaction force is cushioned by the polyurethane reinforcement layer 3 at the bottom of the synthetic leather body 1. When the shoe side is subjected to impact forces, the polyurethane reinforcement layer 3 provides cushioning. Furthermore, the forces experienced by both polyester fiber reinforcement layers 2 and polyurethane reinforcement layers 3 are cushioned by the polyester reinforcement layer 4, resulting in better overall pressure resistance and abrasion resistance. The polyurethane foam filling the first cavity 5 provides good elastic support, the polyamide filling the second cavity 7 provides good abrasion resistance and tear resistance, and the mixture of polypropylene and glass fiber filling the third cavity 9 ensures that it maintains its shape and is not easily deformed under heavy pressure.
