Description

Technical Field

[0001] This application belongs to the technical field of clothing, specifically relating to a garment with chain teeth. Background Technology

[0002] In some garments using related technologies, zippers, produced separately, are sewn onto the edge of the garment. However, this production process requires manufacturing the zipper separately and then attaching it to the edge of the garment, making the production process cumbersome, increasing material costs, and reducing production efficiency.

[0003] To address the aforementioned issues, some manufacturers directly install zipper teeth on the edges of garments. Before installing the teeth, they first bind a core thread to the surface of the fabric edge and then attach the zipper teeth to the fabric edge. However, in this method, the core thread is prone to loosening on the fabric surface, resulting in an unstable core thread and causing the zipper teeth to loosen, affecting the proper opening and closing of the zipper pull. Utility Model Content

[0004] The purpose of this application is to provide a garment with chain teeth that can solve problems such as the instability of the chain teeth installation caused by the weak core thread.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] This application provides a garment with chain teeth, including: fabric, core thread, sewing thread, and multiple chain teeth;

[0007] The fabric has an edge portion, and the core yarn contacts the edge portion and extends along the edge portion;

[0008] The suture is sewn onto the core thread and the edge portion to fix the core thread to the edge portion, and the core thread, the suture, and the edge portion together form a chain tooth fixing portion;

[0009] The plurality of chain teeth are arranged along the extension direction of the core wire, and each chain tooth is connected to the chain tooth fixing part.

[0010] In this embodiment, the core thread can be fixed to the edge of the fabric by sewing, and the core thread is limited by the edge, thereby ensuring the firmness and stability of the connection between the core thread and the edge of the fabric, and preventing the core thread from moving freely. Furthermore, by connecting multiple chain teeth to the chain tooth fixing part formed by the core thread, sewing thread, and edge, the connection area of ​​the chain teeth can be increased, thereby improving the installation stability and firmness of the chain teeth and ensuring their normal use.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0030] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.

[0031] refer to Figures 1 to 12 This application discloses a garment with chain teeth 40. The disclosed garment includes fabric 10, core thread 20, sewing thread 30 and multiple chain teeth 40.

[0032] Fabric 10 is a basic component that provides a mounting base for structures such as core thread 20, seam thread 30, and chain teeth 40. For example, garments with chain teeth 40 may include tops, pants, skirts, etc.; correspondingly, fabric 10 may be the fabric of garments such as tops, pants, and skirts.

[0033] The fabric 10 has an edge portion, and the core thread 20 contacts and extends along the edge portion. Optionally, the core thread 20 may contact different areas of the edge portion to achieve different limiting effects on the core thread 20 through the edge portion.

[0034] The sewing thread 30 is sewn between the core thread 20 and the edge portion to fix the core thread 20 to the edge portion. Based on this, the sewing thread 30 can firmly sew the core thread 20 to the edge portion, ensuring that the core thread 20 is fixed relative to the edge portion, thereby improving the stability and firmness of the core thread 20; furthermore, the contact between the core thread 20 and the edge portion can also improve the strength and rigidity of the edge portion, preventing the fabric 10 from becoming excessively soft and droopy at the edge portion, and improving the installation stability of the chain teeth 40 after installation.

[0035] Furthermore, the core thread 20, the stitching thread 30, and the edge portion together form the chain tooth fixing part, and multiple chain teeth 40 are arranged along the extension direction of the core thread 20, with each chain tooth 40 connected to the chain tooth fixing part. Based on this, the chain teeth 40 can be tightly wrapped around the chain tooth fixing part from all sides, thereby stably and firmly fixed and assembled with the chain tooth fixing part.

[0036] Optionally, multiple chain teeth 40 can be evenly arranged along the extension direction of the core thread 20; in addition, each chain tooth 40 can be connected to the edge and the sewing thread 30. Of course, in some cases, the chain tooth 40 can also be connected to the core thread 20. The specific connection can be selected according to the actual working conditions, as long as the stability and firmness of the chain tooth 40 can be guaranteed. The specific form is not limited.

[0037] In this embodiment, the core thread 20 can be fixed to the edge of the fabric 10 by the sewing thread 30, and the core thread 20 is limited by the edge when in contact with it, thereby ensuring the firmness and stability of the connection between the core thread 20 and the edge of the fabric 10 and preventing the core thread 20 from moving arbitrarily. Furthermore, by connecting multiple chain teeth 40 to the chain tooth fixing part formed by the core thread 20, the sewing thread 30, and the edge, the connection area of ​​the chain teeth 40 can be increased, thereby improving the installation stability and firmness of the chain teeth 40 and ensuring their normal use.

[0038] In some embodiments, the suture 30 can fix the core thread 20 to the outside or inside of the edge portion. When the suture 30 fixes the core thread 20 to the outside of the edge portion, the outer surface of the edge portion provides support for the core thread 20, and the suture 30 also locks and secures the core thread 20. Thus, the combined limiting effect of the suture 30 and the outer surface of the edge portion ensures that the core thread 20 does not move freely outside the edge portion, improving the connection stability and firmness of the core thread 20.

[0039] When the sewing thread 30 fixes the core thread 20 inside the edge portion, the edge portion can wrap the core thread 20, and the sewing of the sewing thread 30 further enhances the locking and fixing effect of the core thread 20, thereby ensuring that the core thread 20 will not move randomly inside the edge portion, and improving the connection stability and firmness of the core thread 20.

[0040] The relative positional relationship between core wire 20 and the edge will be explained in detail below, including:

[0041] In the first embodiment, the core wire 20 is located inside the edge portion.

[0042] refer to Figure 7 The edge region of the fabric 10 may employ a folding structure 10a, which includes a fabric body 11, a folded edge 12, and a connecting portion 13. The folded edge 12 adheres to the edge surface of the fabric body 11, forming a fitting area N between the folded edge 12 and the fabric body 11. The connecting portion 13 connects the edge end of the folded edge 12 and the edge end of the fabric body 11. Furthermore, the area of ​​the folded edge 12 near the connecting portion 13, the area of ​​the fabric body 11 near the connecting portion 13, and the connecting portion 13 together constitute the edge region of the fabric 10.

[0043] Optionally, the fabric body 11, the hem 12, and the connecting portion 13 can be independent of each other. The edge of the hem 12 is fixedly connected to the connecting portion 13, and the edge of the fabric body 11 is fixedly connected to the connecting portion 13. Furthermore, in the thickness direction of the fabric 10, the surface of the hem 12 and the edge surface of the fabric body 11 are bonded together to form a bonding area N. The fixed connection can be achieved by bonding, welding, sewing, heat fusion, etc., and other methods are also possible, which are not specifically limited here.

[0044] In other embodiments, the fabric body 11, the hem 12, and the connecting portion 13 can also be an integral structure, that is, the fabric 10 is a single structure. In the initial state, the fabric 10 can be in a flat form. A certain width of the edge of the fabric 10 is folded 180° to form the hem 12. The area folded 180° can be regarded as the hem 12, the unfolded area can be regarded as the fabric body 11, and the area deformed during the folding process can be regarded as the connecting portion 13.

[0045] The connecting part 13 may be provided with a wire channel M, through which the core wire 20 passes. Based on this, the core wire 20 can be accommodated by the wire channel M, and the inner wall of the wire channel M can also limit the core wire 20.

[0046] Optionally, the connecting part 13 is a planar structure. When the folded edge 12 is attached to the fabric body 11, the connecting part 13 deforms. As the connecting part 13 deforms, the surface of the connecting part 13 gradually forms a line M. In this way, since the inner surface of the connecting part 13 cannot provide space to accommodate the core thread 20, the outer surface of the connecting part 13 can protrude from the outer surface of the folded edge 12 and the outer surface of the fabric body 11 respectively. That is, the connecting part 13 can form a convex structure after accommodating the core thread 20.

[0047] Alternatively, the core wire 20 can be completely threaded through the cable track M, or a section of the core wire 20 can be threaded through the cable track M. The specific choice can be made based on the actual working conditions.

[0048] After the hem 12 is folded over to the fabric body 11, the connecting part 13 can be a tubular structure, the inner cavity of which is the thread track M. It should be noted that when the fabric 10 is flat, the connecting part 13 can be a planar structure. As the hem 12 is gradually folded, the connecting part 13 gradually bends and deforms to form a tubular structure, surrounding the thread track M to provide space for accommodating the core thread 20. Optionally, the tubular structure can be a cylindrical structure; of course, it can also be other shapes, which are not specifically limited here.

[0049] The sidewalls of the tubular structure may have openings, with one side of the opening connected to the edge of the fabric body 11 and the other side connected to the edge of the hem 12. Based on this arrangement, when the hem 12 is against the surface of the fabric body 11, the two sides of the opening can be brought closer together to lock the tubular structure, allowing it to limit the movement of the core thread 20 and improve its stability and strength. It should be noted that the locking effect on the opening can come from the tension of the hem 12 against the surface of the fabric 10, or from the tension of the seam thread 30, ensuring the opening is locked and the core thread 20 is securely wrapped.

[0050] Furthermore, the stitch 30 can be used to sew the core thread 20 and the folded structure 10a to improve the stability of the core thread 20. Optionally, as... Figure 7 As shown, the sewing thread 30 can pierce the connecting part 13 and the core thread 20 to fix the core thread 20 to the connecting part 13. Specifically, the edge area of ​​the fabric 10 is laid flat, the core thread 20 is placed on the edge area of ​​the fabric 10, and then the edge area of ​​the core thread 20 is sewn with the sewing thread 30. After sewing, the edge area is partially folded to tighten the core thread 20. In this way, the core thread 20 can be locked by the sewing thread 30, and the core thread 20 can be tightened by the folded structure 10a formed after folding.

[0051] In other embodiments, the sewing thread 30 may also pierce the core thread 20, the fabric body 11, and the hem 12 to securely connect the core thread 20 to the fabric body 11 and the hem 12. Specifically, the edge area of ​​the fabric 10 is laid flat, the core thread 20 is placed on the edge area of ​​the fabric 10, and a portion of the edge area is folded over to tightly wrap the core thread 20. Then, the fabric body 11 and the hem 12 are sewn together using the sewing thread 30.

[0052] In other embodiments, the core wire 20 can be fixedly connected to the connector 13 by welding, bonding, hot melting, or other methods to ensure the stability and firmness of the core wire 20 within the track M.

[0053] In the second embodiment, the core wire 20 is located outside the edge portion.

[0054] The edge portion may have two opposing chain tooth connecting surfaces and an end face that connects to the two chain tooth connecting surfaces. Optionally, the connection between each chain tooth connecting surface and the end face may be perpendicular or circular arc; no specific limitation is made here.

[0055] In some embodiments, the garment may include a core thread 20, which may contact the end face of the edge portion or a chain tooth connecting surface. In this way, the end face of the edge portion or a chain tooth connecting surface can provide support and limit the core thread 20. In addition, a sewing thread 30 is used to sew and fix the core thread 20 to the end face of the edge portion or a chain tooth connecting surface, thereby ensuring the connection stability and firmness of the core thread 20.

[0056] In other embodiments, the garment may include multiple core threads 20, each of which may be in contact with a single chain tooth connection surface. This single chain tooth connection surface provides support and restraint for the multiple core threads 20. Furthermore, the multiple core threads 20 may be sewn and fixed to a single chain tooth connection surface using sewing thread 30 to ensure the stability and strength of the connection between the multiple core threads 20.

[0057] Multiple core wires 20 can also contact the end face of the edge portion to support and limit the multiple core wires 20 through the end face. Furthermore, multiple core wires 20 can be sewn and fixed to the end face of the edge portion by stitch 30 to ensure the connection stability and firmness of the multiple core wires 20.

[0058] Multiple core wires 20 can also contact the two chain tooth connecting surfaces respectively. The multiple core wires 20 can be evenly distributed on the two chain tooth connecting surfaces or unevenly distributed on the two chain tooth connecting surfaces, so that the two chain tooth connecting surfaces can respectively support and limit the core wires 20 on each of them. Furthermore, the multiple core wires 20 can be sewn and fixed to the two chain tooth connecting surfaces respectively using sewing thread 30 to ensure the connection stability and firmness of the multiple core wires 20.

[0059] Multiple core wires 20 can also contact the end face and a chain tooth connection surface respectively. The multiple core wires 20 can be evenly distributed on the end face and the chain tooth connection surface, or they can be unevenly distributed on the end face and the chain tooth connection surface, so that the end face and the chain tooth connection surface can respectively support and limit the core wires 20 on each of them. Furthermore, the multiple core wires 20 can be sewn and fixed to the end face and the chain tooth connection surface respectively using sewing thread 30 to ensure the connection stability and firmness of the multiple core wires 20.

[0060] Multiple core wires 20 can also contact the end face and the two chain tooth connecting surfaces respectively. The multiple core wires 20 can be evenly distributed on the end face and the two chain tooth connecting surfaces, or they can be unevenly distributed on the end face and the two chain tooth connecting surfaces, so that the end face and the two chain tooth connecting surfaces can respectively support and limit the core wires 20 on each of them. Furthermore, the multiple core wires 20 can be sewn and fixed to the end face and the two chain tooth connecting surfaces respectively using sewing thread 30 to ensure the connection stability and firmness of the multiple core wires 20.

[0061] refer to Figures 10 to 12 In some embodiments, the edge region of the fabric 10 may employ a planar extension structure 10b, meaning the edge region of the fabric 10 has the same structure as other regions, without employing a folding structure 10a. In this case, the zipper tooth connection surface and the end face may be perpendicular to each other. Based on this, one or more core threads 20 can be in contact with the outer surface of the planar extension structure 10b (including the two zipper tooth connection surfaces and the end face) to achieve support and restraint for one or more core threads 20.

[0062] refer to Figures 1 to 6 , Figures 8 to 9 In some other embodiments, the edge region of the fabric 10 may employ a folding structure 10a, which may include a fabric body 11, a folded edge 12, and a connecting portion 13. The folded edge 12 adheres to the edge surface of the fabric body 11, forming a contact area N between the folded edge 12 and the fabric body 11. The connecting portion 13 connects the edge end of the folded edge 12 and the edge end of the fabric body 11. Furthermore, the area of ​​the folded edge 12 near the connecting portion 13, the area of ​​the fabric body 11 near the connecting portion 13, and the connecting portion 13 together constitute the edge portion of the fabric 10. The surfaces of the fabric body 11 and the folded edge 12 that face away from each other form two toothed connecting surfaces of the edge portion, and the side surface of the connecting portion 13 facing away from the folded edge 12 and the fabric body 11 forms the end face of the edge portion. It should be noted that the specific structure of the folding structure 10a here may be the same as that in the first embodiment described above.

[0063] In this case, the two chain tooth connecting surfaces can be connected by an arc-shaped end face. Based on this, one or more core wires 20 can be in contact with the outer surface of the folded structure 10a (including the surface of the fabric body 11 facing away from the folded edge 12, the surface of the folded edge 12 facing away from the fabric body 11, and the surface of the connecting part 13 facing away from the folded edge 12 and the fabric body 11) to achieve the function of supporting and limiting one or more core wires 20.

[0064] refer to Figure 6 To further limit the positioning of the core wire 20, a groove 131 can be provided on the end face of the edge portion (i.e., the side surface of the connecting portion 13 facing away from the folded edge 12 and the fabric body 11). The opening of the groove 131 faces away from the contact area N between the folded edge 12 and the fabric body 11, that is, the opening of the groove 131 is set outward, thus forming an accommodating space. Optionally, a portion of the connecting portion 13 can be bent to form the groove 131.

[0065] At least a portion of the core wire 20 is located in the groove 131. The groove 131 provides space for the core wire 20 and also serves to limit its movement, thus improving its stability. The thread 30 can be sewn into both sides of the groove opening of the groove 131 and into the core wire 20. This thread 30 secures the core wire 20 within the groove 131, preventing it from detaching and further enhancing its connection stability and strength.

[0066] Continue to refer to Figure 6 In some embodiments, the core wire 20 can sequentially pass through one side of the chain tooth connecting surface, one side of the end face, the core wire 20, the other side of the end face, and the chain tooth connecting surface on the other side, and the connecting portion 13 is sewn to the core wire 20 for fixation. Based on this arrangement, on the one hand, the chain tooth connecting surface on one side and one side of the end face can be sewn together by the sewing thread 30, and the chain tooth connecting surface on the other side and the other side of the end face can be sewn together by the sewing thread 30, which can improve the strength of both sides of the groove to a certain extent. On the other hand, the core wire 20 can also be sewn together with the two sides of the groove by the sewing thread 30, thereby ensuring the stability and firmness of the core wire 20.

[0067] To achieve a fixed connection between the folded edge 12 and the fabric body 11, in this embodiment, the folded edge 12 and the fabric body 11 can be fixedly connected by at least one of the following methods: hot melt welding, ultrasonic welding, adhesive bonding, and sewing.

[0068] Among them, the hot melt welding method softens the folded edge 12 and the fabric body 11 by high temperature, so that the two are fused together in at least a part of the bonding area N to achieve a fixed connection and ensure the reliability and firmness of the connection.

[0069] The ultrasonic welding method uses ultrasonic oscillation to generate heat to heat at least a portion of the bonding area N between the folded edge 12 and the fabric body 11, softening the folded edge 12 and the fabric body 11 and fusing them together in at least a portion of the bonding area N, thus ensuring the reliability and strength of the connection between the folded edge 12 and the fabric body 11.

[0070] The adhesive bonding method involves applying adhesives such as glue or tape between the folded edge 12 and the fabric body 11 to bond the two together in at least a portion of the bonding area N, ensuring the reliability and strength of the connection between the folded edge 12 and the fabric body 11.

[0071] The sewing method involves using thread 30 to sew the folded edge 12 to the fabric body 11 together within the fitting area N, ensuring the reliability and strength of the connection between the folded edge 12 and the fabric body 11.

[0072] Of course, one or more of the above methods can be used to achieve a fixed connection between the folded edge 12 and the fabric body 11.

[0073] Optionally, the folded edge 12 and the fabric body 11 can be fixedly connected to the entire area of ​​the bonding area N, or to a part of the bonding area N, as long as the connection stability and firmness between the folded edge 12 and the fabric 10 can be guaranteed.

[0074] In some embodiments, the chain teeth 40 may be connected to the chain tooth fixing part by snap-fit ​​or injection molding.

[0075] When the chain tooth 40 is installed using a snap-fit ​​method, the chain tooth 40 may have a snap-fit ​​protrusion, and correspondingly, the chain tooth fixing part may have a snap-fit ​​hole. The stability and firmness of the chain tooth 40 installation are ensured by the snap-fit ​​cooperation between the snap-fit ​​protrusion and the snap-fit ​​hole. Optionally, the snap-fit ​​hole may be formed in the fabric body 11 and the hem 12.

[0076] When the chain tooth 40 is installed by injection molding, the chain tooth 40 can be directly injection molded to the chain tooth fixing part to ensure the stability and firmness of the chain tooth 40, and also reduce the installation difficulty of the chain tooth 40.

[0077] Optionally, both the folded edge 12 and the fabric body 11 can be provided with injection holes. During the injection process, the injection material can enter the injection hole, and after the injection material cools, it can form an injection rod. The cooperation between the injection rod and the injection hole can improve the installation stability and firmness of the chain teeth 40.

[0078] Optionally, the chain tooth 40 can be a metal chain tooth or a plastic chain tooth.

[0079] When the chain tooth 40 is a metal chain tooth, it can be installed to the chain tooth fixing part by means of snap-fit ​​or other methods; when the chain tooth 40 is a plastic chain tooth, it can be installed to the chain tooth fixing part by means of snap-fit, injection molding or other methods.

[0080] Optionally, a portion of the chain tooth 40 may cover the connecting part 13 and be snapped into place with the connecting part 13, which helps to improve the installation stability and firmness of the chain tooth 40.

[0081] In some embodiments, the fabric 10 may have connecting holes in the area near the edge. Correspondingly, the chain teeth 40 may have connecting portions located in the connecting holes, thereby further improving the installation stability and firmness of the chain teeth 40. Optionally, the connecting holes may be arranged along the extension direction of the core wire 20.

[0082] Optionally, when the chain tooth 40 is installed using a snap-fit ​​method, the connecting part can be a snap protrusion, the connecting hole can be a snap-fit ​​hole, and the snap protrusion and the snap-fit ​​hole engage in a snap-fit ​​fit.

[0083] When the chain tooth 40 is installed by injection molding, the connecting hole can be an injection hole and the connecting part can be an injection rod. That is, during the injection molding process, the injection material flows into the connecting hole to form an injection rod, so as to ensure the installation stability and firmness of the chain tooth 40.

[0084] In addition, the connecting hole can also be a hot melt hole formed during the hot melting process.

[0085] In some embodiments, fabric 10 may be a single-layer fabric; of course, fabric 10 may also be a multi-layer fabric.

[0086] When fabric 10 is a multi-layered fabric, fabric 10 includes multiple fabric layers, which are stacked together, which helps to improve the overall strength and stiffness of fabric 10.

[0087] Alternatively, the multiple fabric layers can be stacked and fixed by at least one of the following methods: bonding, hot melt welding, and ultrasonic welding.

[0088] Furthermore, when the core thread 20 is located inside the edge portion, the core thread 20 contacts the innermost fabric layer in the connecting portion 13 region. When the core thread 20 is located outside the edge portion, if the edge region of the fabric layer adopts a planar extension structure 10b, the core thread 20 can contact the chain tooth connection surface of the outermost fabric layer, or contact the end face of the fabric layer; if the edge region of the fabric layer adopts a folding structure 10a, the core thread 20 can contact the outermost fabric layer at at least one of the fabric body 11, the folded edge 12, and the connecting portion 13.

[0089] In some embodiments, each core thread 20 can be sewn together with a corresponding sewing thread 30, that is, the core thread 20 and the sewing thread 30 are set in a one-to-one correspondence, which can improve the strength of sewing each core thread 20.

[0090] In other embodiments, multiple core threads 20 can be sewn together using the same thread 30, which can save on the amount of thread 30 used, reduce costs, and effectively alleviate the problem of thread 30 tangling.

[0091] The following examples will illustrate the connection relationship between the core thread 20, the sewing thread 30, and the fabric 10:

[0092] refer to Figure 4 The core thread 20 is located on the side surface of the connecting part 13 away from the folded edge 12 and the fabric body 11, so as to support and limit the core thread 20 through the surface; and the core thread 20 and the connecting part 13 are sewn together with the sewing thread 30 to ensure a reliable connection between the core thread 20 and the connecting part 13 and to prevent the core thread 20 from moving at will.

[0093] It should be noted here that, in this method, a portion of the seam 30 is located on the inner surface of the connecting portion 13. To achieve the sewing of the seam 30, as... Figure 3 As shown, first, the fabric 10 is laid flat, and then the core thread 20 is placed on the surface of the edge area of ​​the fabric 10. The core thread 20 and the edge area of ​​the fabric 10 are sewn together with the sewing thread 30. After sewing, a portion of the edge area of ​​the fabric 10 is folded over. In this way, a folded structure 10a can be formed in the edge area of ​​the fabric 10, so that a portion of the sewing thread 30 is located on the inner surface of the connecting part 13 of the folded structure 10a.

[0094] refer to Figure 5 Two core threads 20 respectively contact the side surface of the folded edge 12 away from the fabric body 11 and the side surface of the fabric body 11 away from the folded edge 12, so as to support and limit the core threads 20 at the corresponding positions through the folded edge 12 and the fabric body 11 respectively; and, the core threads 20 and the folded edge 12 and the fabric body 11 are sewn together with sewing thread 30 to ensure a reliable connection between the core threads 20 and the folded edge 12 and between the core threads 20 and the fabric body 11, so as to prevent the core threads 20 from moving at will.

[0095] It should be noted that, firstly, the core thread 20 can be sewn onto the hem 12 and the fabric body 11 using the sewing thread 30, and then the hem 12 can be folded over to fit against the fabric body 11. In this case, two independent sewing threads 30 can be used for sewing. Alternatively, the hem 12 can be folded over to fit against the fabric body 11, and then the core thread 20 can be sewn onto the hem 12 and the fabric body 11 respectively. In this case, the same sewing thread 30 can be used for sewing.

[0096] refer to Figure 8 The two core threads 20 respectively contact the side surface of the folded edge 12 away from the fabric body 11 and the side surface of the fabric body 11 away from the folded edge 12, so as to support and limit the core threads 20 at the corresponding positions through the folded edge 12 and the fabric body 11 respectively; or, the two core threads 20 respectively contact the side surface of the connecting part 13 away from the folded edge 12 and the fabric body 11, so as to support and limit the two core threads 20 through the side surface of the connecting part 13.

[0097] Furthermore, a single thread 30 is used to sew the two core threads 20 together. Specifically, the thread 30 pierces the hem 12 and the fabric body 11 in sequence, and also pierces the two core threads 20 in the direction of the connecting part 13. In this way, the thread 30 can lock the two core threads 20 together, thereby ensuring the stability and firmness of the two core threads 20 at the edge of the fabric 10.

[0098] refer to Figure 9 One core wire 20 contacts the opposite fold 12 of the connecting part 13 and one side surface of the fabric body 11, so as to support and limit the core wire 20 through one side surface of the connecting part 13.

[0099] Furthermore, the core thread 20 is sewn with a sewing thread 30. Specifically, the sewing thread 30 pierces the hem 12 and the fabric body 11 in sequence, and pierces the core thread 20 in the direction of the connecting part 13. In this way, the sewing thread 30 can lock and fix the core thread 20 to ensure the stability and firmness of the core thread 20 on the surface of the connecting part 13.

[0100] refer to Figures 10 to 12 The two core wires 20 contact the opposite sides of the planar extension structure 10b respectively, so as to support and limit the core wires 20 at the corresponding positions through the opposite sides of the planar extension structure 10b.

[0101] Furthermore, a single thread 30 is used to sew the two core threads 20 together. Specifically, the thread 30 pierces the core thread 20 on one side, the planar extension structure 10b, and the core thread 20 on the other side in sequence. In this way, the thread 30 can lock the two core threads 20 together, thereby ensuring the stability and firmness of the two core threads 20 on the planar extension structure 10b.

[0102] In summary, in this embodiment of the application, the core thread 20 is fixed to the edge of the fabric 10 by the stitch 30, which not only improves the stability and firmness of the core thread 20, but also improves the overall strength and rigidity of the edge of the fabric 10. This is beneficial to improving the installation stability of the chain teeth 40, making the chain teeth 40 less prone to loosening, so as to ensure the smooth opening and closing of the zipper pull on the chain teeth 40.

The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
