[0019] In order to make the technical personnel of the prior art better understand the technical scheme of the utility model, the utility model is described in detail below in combination with the drawings and specific embodiments, and it should be explained that, in the case of no conflict, the embodiments of the application and the features in the embodiments can be combined with each other.

[0020] In the description of the utility model, it should be explained that, the orientation or position relation indicated by the terms such as 'up', 'down', 'in', 'out', 'top / bottom end' is the orientation or position relation based on the orientation or position relation shown in the drawing, only for the convenience of describing the utility model and simplifying the description, and not indicating or implying that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, therefore, it can not be understood as the limitation of the utility model.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] A high-strength sewing thread, such as Figures 1-4 As shown, the sewing thread includes a core thread 1, a first elastic thread 2, a second elastic thread 6, a reinforcing layer 3, and a conductive thread 7. The first elastic thread 2 is spirally wound around the outside of the core thread 1. The second elastic thread 6 and the conductive thread 7 form an outer layer 4. A spiral groove 5 is formed between the first elastic thread 2 and the core thread 1. The reinforcing layer 3 is disposed in the groove 5, and the outer layer 4 is wrapped around the outside of the reinforcing layer 3. The second elastic thread 6 and the conductive thread 7 are twisted together, which makes the outer layer 4 also elastic. Under the dual action of the first elastic thread 2 and the second elastic thread 6, the elasticity of the sewing thread is strengthened. The spiral first elastic thread 2 is wound around the outside of the core thread 1, which can further strengthen the elasticity. Moreover, the width of the groove 5 is the same as the width of the reinforcing layer 3, so that the first elastic thread 2 and the reinforcing layer 3 can be tightly attached when not stretched, which improves the shape retention of the sewing thread. It can also return to its original shape after stretching, thereby increasing the strength of the sewing thread and preventing its deformation.

[0023] In one embodiment, both the first elastic thread 2 and the second elastic thread 6 are made of Lycra fiber. Lycra fiber has good elasticity and skin-friendly properties, which makes the sewing thread more widely applicable. In addition, Lycra fiber is not easy to break, which improves the strength of the sewing thread.

[0024] Furthermore, the conductive wire 7 is made of carbon fiber, which has high strength and antistatic properties, preventing the sewing thread from becoming frizzy and improving the strength of the sewing thread.

[0025] In one embodiment, the core thread 1 is made of elastic filament, which is polyester filament and has high strength, so that the core thread 1 can be stretched and return to its original shape, making the sewing thread less likely to break.

[0026] In one embodiment, the reinforcing layer 3 is made of nylon yarn and is disposed inside the outer layer 4 to increase the strength inside the sewing thread. The reinforcing layer 3 is wound inside the groove 5 and does not overlap with the first elastic thread 2, so as not to affect the tensile strength of the first elastic thread 2.

[0027] Structural principle:

[0028] The core thread 1 is made of polyester silk, has elasticity and high tensile strength, and is wrapped with the first elastic silk 2 and the reinforcing layer 3 on the outside, and the two are adhered to each other and are not easy to deform, thereby improving the tensile strength of the sewing thread; and the outer layer 4 is made of carbon fiber and the second elastic silk 6, has high strength, and improves the wear resistance of the sewing thread.
