[0029] In summary, by taking the polyester fiber thread 11 as the center main thread, the strength of the overall sewing thread can be effectively improved due to the high strength of the polyester fiber thread 11. By wrapping the cotton thread 13 around the surface of the polyester fiber thread 11, the surface is relatively soft and has good texture. The nylon thread 12 has high tensile strength and good gloss, which can effectively improve the appearance of the sewing thread. The setting of the adhesive layer 2 makes the entire thread core 1 more stable and does not appear to be layered. The setting of the antistatic agent as the antistatic layer 3 reduces static electricity generated during the sewing process, making the yarn or wire more smooth and easy to handle. During the sewing process, static electricity can cause yarn winding, thread breakage and other problems, affecting the sewing quality and efficiency. The use of an antistatic agent can effectively reduce the occurrence of these problems. The setting of the silicon wax coating, which is a commonly used sewing lubricant that can be applied to the sewing thread to reduce the friction between the threads, make the thread pass through the fabric more smoothly, reduce wear and stretch, thereby reducing the risk of thread breakage.
