Description

Technical Field

[0001] This utility model relates to the field of sewing thread technology, and in particular to a wear-resistant sewing thread. Background Technology

[0002] Sewing thread is a multi-stranded thread used for sewing machines or by hand to sew various materials, such as textiles, plastics, leather products, and books. Sewing thread can be divided into three main categories according to its raw materials: natural fiber sewing thread, synthetic fiber sewing thread, and blended sewing thread.

[0003] Sewing thread is generally made by twisting multiple strands of thread together, and then coating the entire surface of the twisted thread with various coatings to protect it. However, this method of only applying coatings to the outside may directly lead to the breakage of the entire sewing thread when it is damaged, and it cannot provide effective protection and wear resistance. Utility Model Content

[0004] The purpose of this invention is to provide a wear-resistant sewing thread, which solves the problem that sewing threads are generally made by twisting multiple strands of thread cores together and then coating the entire surface of the twisted thread with various coatings to protect it. However, this method of only applying coatings to the outside may directly lead to the breakage of the entire sewing thread when it is damaged, and it cannot provide effective protection and wear resistance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wear-resistant sewing thread includes a core made of nylon. The surface of the core is sequentially provided with a flame-retardant layer, a wear-resistant layer, and a protective layer. The core consists of three strands, which are cross-wound to form a sewing thread body. The surface of the sewing thread body is provided with a protective layer.

[0007] Preferably, the protective layer is a mixture of silicone wax, antistatic agent and softener.

[0008] Preferably, the flame-retardant layer is made of aluminum hydroxide inorganic flame retardant.

[0009] Preferably, the wear-resistant layer is made of polytetrafluoroethylene wear-resistant resin.

[0010] Preferably, the protective layer uses an anti-ultraviolet agent.

[0011] Preferably, the sewing thread body formed by the three strands of thread is bonded together using a sewing thread adhesive.

[0012] This utility model has at least the following beneficial effects:

[0013] The sewing thread is made up of three strands of thread, which are cross-woven together and bonded with a sewing thread adhesive, resulting in a stronger overall structure that prevents it from easily splitting at the break. In addition, each of the three strands of thread has a different protective layer on its surface, so even if the surface coating of one strand of thread is damaged, the entire sewing thread will not break.

[0024] Reference Figure 1-3 A wear-resistant sewing thread includes a core 1 made of nylon. The surface of the core 1 is sequentially provided with a flame-retardant layer 5, a wear-resistant layer 4, and a protective layer 3. The core 1 consists of three strands, which are cross-wound to form a sewing thread body 2. The surface of the sewing thread body 2 is provided with a protective layer 6.

[0025] Furthermore, protective layer 6 uses a mixture of silicone wax, antistatic agent, and softener. Silicone wax has lubricating, high-temperature resistant, and antistatic properties, which can increase the smoothness and abrasion resistance of the sewing thread, making it smoother during sewing and reducing breakage and fraying. The addition of antistatic agent can improve the antistatic performance of the sewing thread, preventing problems such as thread tangling and breakage caused by static electricity accumulation. Softener can improve the softness and feel of the sewing thread, making it more suitable for different sewing needs.

[0026] Furthermore, the flame-retardant layer 5 uses aluminum hydroxide inorganic flame retardant to give the sewing thread flame-retardant properties, making it less likely to burn or burn slowly when exposed to a fire source.

[0027] Furthermore, the wear-resistant layer 4 is made of polytetrafluoroethylene wear-resistant resin. The coating material is dissolved or dispersed in a suitable solvent to prepare a uniform coating liquid. The coating liquid is applied to the surface of the sewing thread, and then cured by heating, drying and other processes to form a strong wear-resistant coating, which improves the wear resistance of the sewing thread and extends its service life. It is suitable for products that need to withstand high friction and wear.

[0028] Furthermore, the protective layer 3 uses an anti-ultraviolet agent. The coating liquid containing the anti-ultraviolet agent is evenly applied to the surface, and then it is adhered to the sewing thread through processes such as drying and curing. This enhances the sun resistance of the sewing thread, improves the sun resistance of the entire thread, and thus extends the service life of the sewing thread.

[0029] Furthermore, the sewing thread body 2 formed by the three strands of thread core 1 is bonded together with sewing thread adhesive to further improve the overall strength of the sewing thread and prevent it from splitting at the break point.

[0030] In summary, using nylon as the thread core 1 and combining three identical thread cores 1 into a complete sewing thread improves the overall strength of the sewing thread. Moreover, nylon has a certain degree of elasticity, making it more adaptable after sewing. When subjected to tension and slightly stretched, all three thread cores 1 will be under tension. Furthermore, the surfaces of the three thread cores 1 are provided with a flame-retardant layer 5, an abrasion-resistant layer 4, and a protective layer 3, which can further improve the performance. The protective layer 6 on the outside of the overall sewing thread can improve its smoothness and abrasion resistance, and play a protective role for the three thread cores 1, making the connection between the three more tight and reducing the occurrence of separation. The diameter of the sewing thread body 2 itself can be selected according to the appropriate nylon thread core 1 according to the usage requirements.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
