[0002] This application claims priority to the following Chinese patent applications filed on March 10, 2025, with application number 202510279777.4, entitled "Clothing with Chain Teeth"; filed on March 10, 2025, with application number 202520409704.8, entitled "Clothing with Chain Teeth"; filed on August 25, 2024, with application number 202422061033.9, entitled "Textile Articles with Directly Installed Plastic Chain Teeth"; and filed on August 25, 2024, with application number 202422061032.4, entitled "Textile Articles Equipped with Plastic Chain Teeth", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application belongs to the technical field of clothing, specifically relating to a garment with chain teeth, a fabric product with directly installed plastic chain teeth, and a fabric product equipped with plastic chain teeth. Background Technology

[0004] 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.

[0005] 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. Summary of the Invention

[0006] This application provides a garment with chain teeth, comprising: fabric, core thread, and multiple chain teeth; the fabric includes a fabric body, a hem, and a connecting portion connecting the fabric body and the hem, the connecting portion having a thread channel, and the core thread passing through the thread channel; the fabric body includes a first surface located in the edge region and facing the hem, the hem includes a second surface facing the fabric body, the second surface is attached to the first surface and forms an attachment area between the two, and the first surface and the second surface are fixedly connected in at least a portion of the attachment area to lock the connecting portion and to wrap the core thread tightly through the connecting portion; the multiple chain teeth are arranged along the extension direction of the core thread, and each chain tooth is connected to the area where the connecting portion of the fabric is located.

[0007] This application provides a fabric article for directly mounting plastic chain teeth. The fabric article includes a mounting part for mounting plastic chain teeth and a plurality of plastic chain teeth mounted on the mounting part in a gap manner. The feature is that a core thread and a sewing thread are arranged on the mounting part, the sewing thread is inserted through the mounting part, the core thread is positioned on the mounting part through the sewing thread, and the plastic chain teeth are installed on the mounting part by injection molding and simultaneously bite the core thread and the sewing thread.

[0008] The textile products mentioned include, but are not limited to, common textile products such as clothing, bags, shoes, hats, bed sheets, duvet covers, and chair covers.

[0009] The mounting portion is a part of the fabric used to make the textile product. This portion is generally located at the edge of the fabric or at the edge of a partial opening in the fabric. The mounting portion can be directly placed in an injection molding machine to injection mold plastic teeth; that is, the width of the mounting portion is equal to or slightly larger than the width of the plastic teeth covering the plastic on the fabric. The mounting portion can be a single layer or a double layer of fabric. Generally, to reduce the unraveling of threads at the edges after the fabric is cut, the edges of the textile product can be finished by laser cutting and heat melting, or by using stitching to seal the edges.

[0010] The mounting portion is a part of the fabric used to make the textile product. This portion is generally located at the edge of the fabric or at the edge of a partial opening in the fabric. The mounting portion can be directly placed in an injection molding machine to injection mold plastic teeth; that is, the width of the mounting portion is equal to or slightly larger than the width of the plastic teeth covering the plastic on the fabric. The mounting portion can be a single layer or a double layer of fabric. Generally, to reduce the unraveling of threads at the edges after the fabric is cut, the edges of the textile product can be finished by laser cutting and heat melting, or by using stitching to seal the edges.

[0011] The specific structure of the installation part is flexible and varied. The following describes several specific implementation methods.

[0012] In the first embodiment, the mounting portion is a single layer of fabric, with at least a portion of the stitching passing through the core thread, and the stitching binding the core thread. The stitching not only passes through the mounting portion but also through the core thread.

[0013] Based on this embodiment, injection pre-drilled holes are formed at the mounting location by drilling. The plastic chain teeth are installed at the mounting location by injection molding and cover the injection pre-drilled holes from top to bottom. Moreover, the plastic during injection molding passes through the injection pre-drilled holes to form connecting posts that connect the plastic chain teeth located on the upper and lower sides of the mounting location.

[0014] The second embodiment utilizes a concealed double-layer fabric structure formed by stacking two single-layer fabrics. The double-layer fabric includes an upper base fabric and a lower base fabric. The edges of the upper and lower base fabrics are aligned vertically to form the mounting area. A stitch passes through both the upper and lower base fabrics. The core thread is positioned on the outer edge of the lower base fabric, with a portion of the stitch passing through and binding the core thread. The double-layer fabric is formed by overlapping two independent single-layer fabrics with their edges aligned. Further, the two fabrics can be joined together using stitches or an adhesive layer to reduce relative movement between them. The lower base fabric has two sides: an inner side facing the upper base fabric and an outer side facing it. In this embodiment, the core thread is positioned on the outer edge of the lower base fabric.

[0015] The third embodiment is a hidden double-layer fabric structure formed by folding a single layer of fabric inward. The double-layer fabric includes an upper base fabric and a lower base fabric. The folded edges of the upper and lower base fabrics are the mounting parts. The sewing thread passes through the upper and lower base fabrics. The core thread is arranged on the outer edge of the lower base fabric. Part of the sewing thread passes through the core thread, and part of the sewing thread is tied to the core thread.

[0016] The fourth embodiment is a hidden double-layer fabric structure formed by folding a single layer of fabric inward. The double-layer fabric includes an upper base fabric and a lower base fabric. The folded edges of the upper and lower base fabrics are the mounting parts. The sewing thread passes through the upper and lower base fabrics. The core thread is arranged at the folded edges of the double-layer fabric and is wrapped by the double-layer fabric. Part of the sewing thread is arranged along the side of the core thread.

[0017] In a further embodiment, part of the stitching simultaneously passes through the upper base fabric, the core thread, and the lower base fabric. Alternatively, part of the stitching binds the upper base fabric, the core thread, and the lower base fabric from the outside.

[0018] A further technical solution may include an intermediate adhesive layer disposed within the double-layer fabric, which is used to bond the upper base fabric and the lower base fabric together. Wherein, when the core wire is wrapped by the double-layer fabric, the intermediate adhesive layer can simultaneously bond the upper base fabric, the lower base fabric, and the core wire, which further defines the position of the core wire.

[0019] A further technical solution could be that a waterproof membrane layer is provided on the outer surface of the fabric layer at the installation location, and part of the waterproof membrane layer is covered by the plastic chain teeth.

[0020] This application provides a fabric article equipped with plastic chain teeth. The fabric article includes a concealed double-layer structure formed by folding the fabric layers inward. The double-layer structure includes an upper base fabric and a lower base fabric. The folded edge area of ​​the double-layer structure is used to install a plurality of spaced plastic chain teeth. The feature is that it further includes a heat-adhesive film, which not only adheres to the inner edge area of ​​the lower base fabric but also to the upper base fabric, thereby achieving edge finishing at the junction of the upper and lower base fabrics. Injection molding pre-drilled holes are formed in the folded edge area of ​​the double-layer structure by punching. The plastic chain teeth are installed in the folded edge area of ​​the double-layer structure by injection molding, covering the injection molding pre-drilled holes from both top and bottom. Furthermore, the plastic during injection molding passes through the injection molding pre-drilled holes to form connecting posts connecting the plastic chain teeth located on the upper and lower sides of the double-layer structure.

[0021] The textile products mentioned include, but are not limited to, common textile products such as clothing, bags, shoes, hats, bed sheets, duvet covers, and chair covers.

[0022] The folded edge region refers to the area near the folded edge of the fabric used to make the textile. This region can be located at the edge of the fabric or at the edge of a partial opening in the fabric. The folded edge region of the fabric can be directly placed in an injection molding machine to injection mold plastic chain teeth. Generally, to reduce the unraveling of the threads at the edge after the fabric is cut, the fabric of the textile is usually trimmed by laser cutting, and then the inner edge region of the lower base fabric is bonded to the upper base fabric using a heat-bonding film.

[0023] The double-layer structure is formed by folding the edges of the fabric layers in the folded edge area, creating two layers. The lower base fabric is an inwardly folded layer, and generally, the width of the lower base fabric is greater than the width of the plastic chain teeth covering the lower base fabric.

[0024] The injection molding pre-set hole is a through hole formed by laser, hot stamping or mechanical stamping. The through hole penetrates the fabric layer. If a laser or hot stamping method is used to drill a hole in the double fabric layer, the edge of the hole is locally burned by high temperature, and the cut of the fabric is sintered and does not easily fall apart. In addition, cutting the double fabric layer under a compressed state can also make the edge of the injection molding pre-set hole weld together, so that the plastic can pass smoothly through the injection molding pre-set hole during injection molding.

[0025] A further technical solution may include a suture thread, which is arranged along the folded edge region of the double-layer structure. The suture thread can pass through the upper and lower base fabrics of the double-layer structure to sew the two fabric layers together. The suture thread is arranged on the side of the injection molding pre-set hole, and part of the suture thread is covered by the plastic chain teeth. The stitching method of the suture thread is relatively flexible. Two common stitching methods are as follows: the first is a flat stitch, where the suture thread is arranged parallel to the folded edge of the double-layer structure, and the suture thread can be a single thread or multiple threads arranged side by side; the second is a serged stitch, where the suture thread is arranged in a crisscross pattern and wraps around a portion of the fabric near the folded edge of the double-layer structure, thereby forming a serged stitch structure.

[0026] A further technical solution may also include a core wire, which is arranged at the folded edge region of the double-layer structure and held between the upper and lower base fabrics of the double-layer structure. At least one stitch extending along the length of the core wire is arranged on the inner side region of the core wire, and the stitch connects the upper and lower base fabrics. Part of the stitch and the core wire are covered by the plastic chain teeth. The inner side region of the core wire refers to the area located next to the core wire and away from the folded edge; viewed from the front, this area is elongated and extends along the length of the core wire. Since the injection-molded pre-drilled hole can be arranged on the inner or outer side of the stitch, there are two possibilities: first, the injection-molded pre-drilled hole only passes through the upper and lower base fabrics; second, the injection-molded pre-drilled hole is arranged close to the core wire, so that in addition to passing through the upper and lower base fabrics, the injection-molded pre-drilled hole also partially passes through but does not break the core wire.

[0027] A further technical solution may also include a core wire, which is arranged in the folded edge area of ​​the double-layer structure and held between the upper and lower base fabrics of the double-layer structure. A stitching thread is provided at the location of the core wire. The stitching thread is arranged outside the upper and lower base fabrics and can pass through the upper and lower base fabrics from the inner side area of ​​the core wire to bind the core wire, upper base fabric, and lower base fabric tightly from the outside. Part of the stitching thread and core wire are covered by the plastic chain teeth.

[0028] A further technical solution could be that a waterproof membrane layer is provided on the outer surface of the double-layer structure, the injection molding pre-set hole passes through the waterproof membrane layer, the stitching does not pass through the waterproof membrane layer, and part of the waterproof membrane layer is covered by the plastic chain teeth.

[0029] A further technical solution may also include an intermediate adhesive layer, which is disposed in the double-layer structure, the double-layer structure including an upper base fabric and a lower base fabric, the intermediate adhesive layer being used to bond the upper base fabric and the lower base fabric together; the injection molding pre-placed hole formed by punching penetrates the upper base fabric, the lower base fabric and the intermediate adhesive layer.

[0030] A further technical solution may include a core wire, which is arranged in the folded edge area of ​​the double-layer structure and held between the upper and lower base fabrics. The intermediate adhesive layer can simultaneously bond the upper base fabric, the lower base fabric, and the core wire. Furthermore, it may include a sewing thread, which is arranged along the extension direction of the core wire. The sewing thread can pass through the upper and lower base fabrics of the double-layer structure to sew the two fabric layers together. The sewing thread is arranged on the side of the injection molding pre-set hole, and part of the sewing thread is covered by the plastic chain teeth. The intermediate adhesive layer can simultaneously bond the upper base fabric, the lower base fabric, the core wire, and the sewing thread. Furthermore, a waterproof membrane layer is also provided on the outer surface of the double-layer structure, and part of the waterproof membrane layer is covered by the plastic chain teeth.

Detailed Implementation

[0064] 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.

[0065] 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.

[0066] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.

[0067] Referring to Figures 1 to 6, this application discloses a garment with chain teeth 40. The disclosed garment includes fabric 10, core thread 20 and multiple chain teeth 40.

[0068] Fabric 10 is a basic component that can provide a mounting base for other components. For example, core threads 20, chain teeth 40, and other structures can be mounted onto fabric 10. For instance, garments with chain teeth 40 may include tops, trousers, skirts, etc.; correspondingly, fabric 10 may be the fabric of such garments. Fabric 10 may include a fabric body 11, a hem 12, and a connecting portion 13 that connects the fabric body 11 and the hem 12.

[0069] Optionally, the fabric 10 can be a single integral structure. In this case, the fabric body 11, the hem 12, and the connecting part 13 can be a single integrated structure. Initially, the fabric 10 can be a flat piece of fabric 10. Then, a portion of the edge of the fabric 10 is folded 180° to form a hem structure. The area folded 180° is the hem 12, the area deformed during the folding process is the connecting part 13, and the area not folded is the fabric body 11.

[0070] Of course, the fabric 10 can also be a split structure. In this case, the fabric body 11, the hem 12 and the connecting part 13 can be independent structures and can be fixedly connected later. For example, the hem 12 and the connecting part 13 can be fixedly connected by means of bonding, welding, sewing, etc., as well as the fabric body 11 and the connecting part 13.

[0071] In the initial state, the folded edge 12 can be a separate strip structure, the fabric body 11 is a flat structure, and the connecting part 13 is a separate strip structure. The edge of the folded edge 12 is fixedly connected to the connecting part 13, the edge of the fabric body 11 is fixedly connected to the connecting part 13, and the folded edge 12 is attached to the edge area of ​​the fabric body 11. In this way, a folded edge structure can be formed.

[0072] In some embodiments, the connecting portion 13 may be provided with a thread track M, through which the core thread 20 passes. Optionally, the connecting portion 13 may also be a planar strip structure. When the folded edge 12 is in contact with the fabric body 11, the connecting portion 13 undergoes bending deformation, thereby forming the thread track M through the deformation of the connecting portion 13. However, the inner surface of the connecting portion 13 cannot provide space to accommodate the core thread 20, causing the outer surface of the connecting portion 13 to protrude from the outer surface of the folded edge 12, and the outer surface of the connecting portion 13 to also protrude from the outer surface of the fabric body 11. That is, the connecting portion 13 can form a convex structure after accommodating the core thread 20.

[0073] Considering that although the folded edge 12 and the fabric body 11 are attached, they cannot be relatively fixed, thus failing to secure the core wire 20, resulting in unstable installation and easy movement of the core wire 20. Based on this situation, in this embodiment, the fabric body 11 may include a first surface 111 located in the edge region and facing the folded edge 12, and the folded edge 12 may include a second surface 121 facing the fabric body 11. The second surface 121 is attached to the first surface 111, forming an attachment area N between them. At least a portion of the first surface 111 and the second surface 121 within the attachment area can be fixedly connected to lock the connecting part 13, and the connecting part 13 provides a wrapping effect for the core wire 20, ensuring the stability and firmness of the core wire 20 installation.

[0074] Of course, in other embodiments, in addition to the aforementioned function of the connecting portion 13 tightly wrapping around the core wire 20 to fix the core wire 20, other methods can be introduced to further ensure the relative fixation between the core wire 20 and the connecting portion 13. Optionally, the core wire 20 and the connecting portion 13 can be fixedly connected by sewing, bonding, welding, fusion, etc., to ensure the stability and firmness of the core wire 20.

[0075] In this embodiment, a plurality of chain teeth 40 are arranged on the fabric 10 along the extension direction of the core thread 20, and each chain tooth 40 is connected to the fabric 10 and located in the area where the connecting portion 13 is located. Based on this, the chain teeth 40 can tightly wrap around the area surrounding the core thread 20, thereby stably and firmly fixing and assembling it with the fabric 10. Optionally, the plurality of chain teeth 40 can be evenly arranged along the extension direction of the core thread 20.

[0076] Optionally, each chain tooth 40 can be connected to the connecting portion 13, or each chain tooth 40 can be connected to the bonding area N of the hem 12 and the fabric body 11, near the connecting portion 13, or each chain tooth 40 can be connected to both the connecting portion 13 and the bonding area N near the connecting portion 13. Other methods are also possible, as long as the stability and firmness of the chain teeth 40 are guaranteed; the specific form is not limited.

[0077] Based on the above configuration, the hem 12 and the fabric body 11 are bonded together through the second surface 121 and the first surface 111, which can improve the strength and rigidity of the edge of the fabric 10, so that the edge of the fabric 10 is no longer excessively soft and droopy. After the chain teeth 40 are installed, it can help improve the installation stability of the chain teeth 40. The connecting part 13 connecting the hem 12 and the fabric body 11 can be provided with a thread channel M to accommodate the core thread 20. The second surface 121 of the hem 12 and the first surface 111 of the fabric 10 are fixedly connected in at least a part of the bonding area N. In this way, the connecting part 13 can play a locking role, so that the core thread 20 located in the thread channel M can be tightly wrapped by the connecting part 13, thereby improving the stability and firmness of the core thread 20.

[0078] Compared to sewing the core thread 20 onto the surface of the fabric 10, the embodiments of this application can enclose the core thread 20 within the fabric 10, thereby improving the installation stability and firmness of the core thread 20, further enhancing the installation stability and firmness of the chain teeth 40, and ensuring the normal use of the chain teeth 40.

[0079] In some embodiments, the first surface 111 and the second surface 121 can be fixedly connected over the entire area of ​​the mating region N. In this case, the fixed connection area between the first surface 111 and the second surface 121 is maximized, improving the firmness between them and ensuring the firmness between the folded edge 12 and the fabric body 11. This prevents the folded edge 12 from separating from the fabric body 11 or from partially lifting. Furthermore, the fixed connection between the first surface 111 and the second surface 121 also achieves a locking effect on the connecting portion 13, allowing the locking portion to tightly wrap around the core wire 20 and ensuring the installation stability and firmness of the core wire 20. This method is not limited to the width of the folded edge 12.

[0080] In other embodiments, the first surface 111 and the second surface 121 can be fixedly connected in a portion of the bonding area N near the connecting portion 13. In this case, the connecting portion 13 can be locked by the fixed connection of the portion, thereby allowing the locking portion to tightly wrap the core wire 20 and ensure the installation stability and firmness of the core wire 20. Of course, this method can also fix the folded edge 12 and the fabric body 11 at one end of the bonding area N near the connecting portion 13 (i.e., at the bonding seal N1) to prevent the folded edge 12 from detaching from the fabric body 11. This method is mainly suitable for cases where the width of the folded edge 12 is relatively small.

[0081] In some embodiments, the first surface 111 and the second surface 121 can be fixedly connected by at least one of the following methods: hot melt welding, ultrasonic welding, and adhesive bonding.

[0082] The hot melt welding method involves softening the folded edge 12 against the fabric body 11 at high temperature, causing the first surface 111 and the second surface 121 to fuse together in at least a portion of the bonding area N, thereby achieving a fixed connection and ensuring the reliability and strength of the connection.

[0083] 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 so that the first surface 111 and the second surface 121 are fused together in at least a portion of the bonding area N, ensuring the reliability and firmness of the connection between the folded edge 12 and the fabric body 11.

[0084] The adhesive bonding method involves applying adhesives such as glue or tape between the first surface 111 and the second surface 121 to bond the first surface 111 and the second surface 121 together in at least a portion of the bonding area N, thereby ensuring the reliability and strength of the connection between the folded edge 12 and the fabric body 11.

[0085] Of course, this is not the only way; other methods can also be used to achieve a fixed connection between the first surface 111 and the second surface 121.

[0086] In some embodiments, the fabric 10 may have multiple connecting holes in the area within the bonding region N. These connecting holes are arranged along the extension direction of the core thread 20 and connect with the corresponding chain teeth 40. Therefore, the engagement of the chain teeth 40 with the connecting holes helps to improve the installation stability of the chain teeth 40.

[0087] Optionally, both the hem 12 and the fabric body 11 may be provided with multiple connecting holes, and the multiple connecting holes of the hem 12 and the multiple connecting holes of the fabric body 11 may be provided in a one-to-one correspondence or staggered arrangement.

[0088] Optionally, the fabric body 11 may have a third surface 113 that is opposite to the first surface 111, the hem 12 may have a fourth surface 122 that is opposite to the second surface 121, the connecting hole is a blind hole, and the connecting hole is located on the third surface 112 and the fourth surface 122 respectively.

[0089] In addition, the connecting holes can also be through holes, and the multiple connecting holes of the folded edge 12 can be connected to the multiple connecting holes of the fabric body 11 in a one-to-one correspondence.

[0090] It should be noted that the aforementioned connecting hole can be used to install the chain tooth 40; in addition, the connecting hole can also be formed during the process of fixing the first surface 111 and the second surface 121.

[0091] To enable the installation of the chain tooth 40, the chain tooth 40 may be provided with a connecting part, and the connecting part is located in the connecting hole, which can further improve the installation stability and firmness of the chain tooth 40.

[0092] Optionally, the connection hole can be a snap-fit ​​hole, an injection hole, or a hot melt hole 14.

[0093] In some embodiments, the chain teeth 40 may be connected to the area where the joint portion 13 of the fabric 10 is located by snap-fit ​​or injection molding.

[0094] When the chain tooth 40 is installed using a snap-fit ​​method, the chain tooth 40 may have a snap protrusion, and correspondingly, the connecting hole may be a snap-fit ​​hole. The stability and firmness of the chain tooth 40 installation are ensured by the snap-fit ​​cooperation between the snap protrusion and the snap-fit ​​hole.

[0095] When the chain teeth 40 are installed by injection molding, the chain teeth 40 can be directly injection molded into the area where the connecting part 13 of the fabric 10 is located, so as to ensure the stability and firmness of the chain teeth 40, and also reduce the installation difficulty of the chain teeth 40.

[0096] The connecting hole is the injection hole. During the injection process, the injection material can enter the injection hole. After the injection material cools, it forms the injection rod. The cooperation between the injection rod and the injection hole can improve the installation stability and firmness of the chain tooth 40.

[0097] Optionally, the chain tooth 40 can be a metal chain tooth or a plastic chain tooth.

[0098] When the chain tooth 40 is a metal chain tooth, it can be installed to the area where the connecting part 13 of the fabric 10 is located by means of snap-fit ​​or other methods; when the chain tooth 40 is a plastic chain tooth, it can be installed to the area where the connecting part 13 of the fabric 10 is located by means of snap-fit, injection molding or other methods.

[0099] 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.

[0100] Referring to Figures 2 to 6, in some embodiments, the first surface 111 and the second surface 121 can be fixedly connected by hot-melt welding. In this case, the connection hole can be a hot-melt hole 14, and the first surface 111 and the second surface 121 form a hot-melt area around the hot-melt hole 14. The first surface 111 and the second surface 121 are fixedly connected through the hot-melt area.

[0101] Based on this configuration, the first surface 111 and the second surface 121 can be fixedly connected through the hot-melt area around the multiple hot-melt holes 14, so as to ensure the reliability and firmness of the connection between the first surface 111 and the second surface 121.

[0102] Optionally, multiple hot-melt holes 14 can be arranged at intervals along the extension direction of the core wire 20 to form a hot-melt hole row; of course, multiple hot-melt hole rows can also be set. Specifically, when the width of the folded edge 12 is less than the preset width, one hot-melt hole row can be set; when the width of the folded edge 12 is greater than or equal to the preset width, multiple hot-melt hole rows can be set.

[0103] Optionally, the fabric body 11 may have a third surface 112 facing away from the first surface 111, and the hem 12 may have a fourth surface 122 facing away from the second surface 121. The heat fusion hole 14 is a blind hole, and the heat fusion hole 14 is located on the third surface 112 and the fourth surface 122 respectively. The blind hole form of the heat fusion hole 14 is more suitable for scenarios where the fabric body 11 and the hem 12 have a large thickness.

[0104] Optionally, as shown in Figures 3 and 4, the hot-melt holes 14 can be through holes, and the multiple hot-melt holes 14 of the folded edge 12 can be connected one-to-one with the multiple hot-melt holes 14 of the fabric body 11. The through-hole design of the hot-melt holes 14 helps to increase the welding area, thereby improving the strength.

[0105] Based on the above configuration, during the hot melt welding process, the second surface 121 and the first surface 111 can be heated through blind holes or through holes respectively, thereby softening at least part of the contact area N of the first surface 111 and the second surface 121 and hot melting together, that is, forming an adhesive area between the first surface 111 and the second surface 121, ensuring the reliability and firmness of the connection between the folded edge 12 and the fabric body 11.

[0106] Furthermore, the heat-fusion holes 14 can be through holes, and the multiple through holes of the folded edge 12 correspond one-to-one with the multiple through holes of the fabric body 11. Based on this arrangement, heating of the second surface 121 and the first surface 111 can be achieved, thereby softening at least a portion of the bonding area N between the first surface 111 and the second surface 121 and heat-fusion together, that is, forming an adhesive area between the first surface 111 and the second surface 121, ensuring the reliability and firmness of the connection between the folded edge 12 and the fabric body 11.

[0107] Of course, the multiple through holes of the folded edge 12 and the multiple through holes of the fabric body 11 can also be staggered. In this case, the heating of the second surface 121 and the first surface 111 can also be achieved, so that the first surface 111 and the second surface 121 soften and heat-melt together, that is, an adhesive area is formed between the first surface 111 and the second surface 121, ensuring the reliability and firmness of the connection between the folded edge 12 and the fabric body 11.

[0108] Referring to Figures 2 to 6, in some embodiments, the connecting portion 13 can be a cylindrical structure, the inner cavity of which is the thread channel M. It should be noted that when the fabric 10 is in a flat state, the connecting portion 13 can be a planar structure. As the hem 12 is gradually folded, the connecting portion 13 gradually bends and deforms to form a cylindrical structure, surrounding the thread channel M to provide space for accommodating the core thread 20. Optionally, the cylindrical structure can be a circular cylinder; of course, it can also be other shapes, which are not specifically limited here.

[0109] 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 facilitate locking the tubular structure, allowing it to tightly wrap 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, to ensure the opening is locked and to guarantee the tight wrapping of the core thread 20.

[0110] To further improve the stability and strength of the core thread 20, the garment may also include a sewing thread 30, as shown in Figure 4, which is sewn onto the connecting part 13 and the core thread 20. Based on this, the sewing thread 30 can secure the core thread 20 to the connecting part 13, thereby ensuring the relative stability and strength between the core thread 20 and the fabric 10. It should be noted that in this method, the sewing thread 30 can directly pierce through the connecting part 13 and the core thread 20.

[0111] Optionally, the sewing position of the stitch 30 can be located between the center line of the core thread 20 and the sealing opening N1 of the hem 12 and the fabric body 11. Based on this, on the one hand, the stitch 30 can achieve the locking effect of the connecting part 13 and wrap the core thread 20 tightly through the connecting part 13; on the other hand, the stitch 30 can also directly fix the core thread 20 and the connecting part 13. Therefore, the installation stability and firmness of the core thread 20 can be further improved. It should be noted here that the sealing opening N1 is the port of the bonding area N near the connecting part 13.

[0112] Of course, the stitching position of the suture 30 can also be located on the side opposite to the sealing N1 of the center line of the core thread 20. This method can also achieve the fixation of the core thread 20 and the connecting part 13.

[0113] Optionally, there may be one or more sutures 30. When there are multiple sutures 30, the stitching strength between the joint 13 and the core thread 20 can be further improved, which is beneficial to improving the stability and firmness of the core thread 20.

[0114] In other embodiments, the stitch 30 can also be sewn onto the folded edge 12 in the area of ​​the fabric body 11 within the bonding area N. In this case, when the first surface 111 and the second surface 121 are fixedly connected, the stitch 30 can further improve the firmness and stability. In addition, when the stitch 30 is close to the connecting part 13, it can also lock the connecting part 13 so that the connecting part 13 can tightly wrap the core thread 20, thereby improving the stability and firmness of the core thread 20.

[0115] Of course, the stitch 30 can also be sewn onto the connecting part 13 and the core thread 20, as well as the folded edge 12 onto the fabric body 11. In this way, the core thread 20 can be directly fixed, and the core thread 20 can be tightly wrapped by locking the connecting part 13, thereby further improving the stability and firmness of the core thread 20.

[0116] Optionally, the seam 30 can be one or more. When there are multiple seams 30, the stitching strength between the folded edge 12 and the fabric body 11 can be further improved, which is beneficial to improving the binding effect of the core thread 20.

[0117] In this embodiment of the application, the fabric 10 can be a single layer, as shown in Figures 1 to 4; of course, the fabric 10 can also be multiple layers, as shown in Figures 5 and 6, that is, the fabric 10 can include multiple fabric layers stacked together.

[0118] Optionally, the multiple fabric layers can be stacked and fixed together by at least one of the following methods: adhesive bonding, hot melt welding, and ultrasonic welding. When the fabric 10 includes multiple fabric layers, the fabric body 11, the hem 12, and the connecting portion 13 can all be composed of multiple fabric layers.

[0119] Considering that the folded edge 12 can be folded to the surface of the fabric body 11, the connecting part 13 can be deformed accordingly. Thus, after folding, the part of the innermost fabric layer located inside the folded edge 12 fits into the part of the innermost fabric layer located inside the fabric body 11, and the connecting part 13 is provided with a thread M.

[0120] When installing the chain teeth 40, each chain tooth 40 can be connected to the area of ​​the outermost fabric layer of the fabric 10 located within the joint 13. In this way, by setting multiple fabric layers, the overall strength and rigidity of the fabric 10 can be improved, thereby improving the stability and firmness of the chain teeth 40 in bearing and installation.

[0121] It should be noted that the folded edge 12 can be folded towards the side of the fabric body 11. The side facing the folding direction is the inner side, and the side away from the folding direction is the outer side.

[0122] In summary, in this embodiment of the application, the core wire 20 is wrapped tightly with fabric 10, which improves the stability and firmness of the core wire 20 and also helps to improve 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.

[0123] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. 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.

[0124] Previously, the manufacturing process for fabric products with injection-molded zipper teeth typically involved preparing a pair of specialized fabric strips, then using injection molding to attach the zipper teeth to the edges of the fabric strips to create a zipper tooth tape. Finally, the zipper tooth tape was sewn together with the fabric to produce the fabric product with injection-molded zipper teeth. The fabric strip became an essential component of zippered fabric products. However, to increase the bonding strength between the injection-molded zipper teeth and the fabric strip, the fabric strip was generally made of synthetic materials such as polyester fiber and nylon. This resulted in thick, hard, and rough surfaces with poor elasticity. Using such zipper tooth tape in some thin fabric products would significantly affect the softness and comfort of the fabric.

[0125] To address this, improvements have been made to the manufacturing process of zipper teeth and fabric products. For example, Chinese invention patent CN108402607B discloses a zippered product, zipper tooth components, and a method for manufacturing the zippered product. The zippered product has a pair of zipper tooth components, which are formed by installing zipper teeth onto a fixing component. The zipper-mounted component has a pair of tooth mounting edges at opposite positions for mounting the tooth components. The fixing component has a tooth retaining portion and an extension portion extending further along the length relative to the tooth retaining portion. The zipper tooth components are fixed to the tooth mounting edges of the zipper-mounted component by a sewing part for fixing the sewing thread, and the extension portion of the fixing component is fixed to the tooth mounting edges by the sewing part for fixing. This zipper tooth mounting method eliminates the need for fabric tape, but because both the sewing thread and the fixing component have a certain degree of elasticity, they are prone to deformation under stress, resulting in displacement between the zipper teeth and the zipper-mounted component, creating large gaps that are unsightly.

[0126] In order to further improve the bonding effect between the injection-molded chain teeth and the fabric of the product, and also to avoid using the intermediate component of the fabric tape to further improve the softness and comfort of the product, the applicant thought of directly injection molding the chain teeth to the fabric of the product. However, the existing injection-molded chain tooth technology is an improvement based on the use of fabric tape. Therefore, the applicant has conducted continuous technical experiments and improvements to obtain the fabric product with directly installed plastic chain teeth proposed in this invention.

[0127] The structure of the fabric product with directly installed plastic chain teeth, which applies the technical solution of the present invention, will be further described below with reference to the accompanying drawings.

[0128] Except where explicitly stated that they are equivalent or alternative implementation schemes, the various implementation details disclosed below may be selectively applied or combined in one embodiment even if they are not directly related or synergistic in terms of function.

[0129] As shown in Figures 7 to 10, a fabric product a1 is provided for directly mounting plastic chain teeth a3. The fabric product a1 includes a mounting part a2 for mounting the plastic chain teeth a3 and a plurality of plastic chain teeth a3 installed in the mounting part a2 in a gap manner. A core thread a7 and a sewing thread a6 are arranged in the mounting part a2. The sewing thread a6 passes through the mounting part a2, and the core thread a7 is positioned in the mounting part a2 through the sewing thread a6. The plastic chain teeth a3 are installed in the mounting part a2 by injection molding and simultaneously bite the core thread a7 and the sewing thread a6.

[0130] The mounting portion a2 is a part of the fabric used to make the textile product a1. This portion is generally located at the edge of the fabric or at the edge of a partial opening in the fabric. The mounting portion a2 can be directly placed in an injection molding machine to injection mold plastic chain teeth a3. The width of the mounting portion a2 is equal to or slightly larger than the width of the plastic chain teeth a3 covering the fabric. By setting the core thread a7 and the seam thread a6, the thickness of the edge portion can be increased. After the plastic chain teeth a3 are injection molded, they can grip the core thread a7 and the seam thread a6, thereby improving the connection stability between the plastic chain teeth a3 and the mounting portion a2, and greatly improving the service life of the textile product a1. In addition, since the mounting portion a2 uses the same fabric as the textile product a1, there is no need to sew fabric tape, making the processing simpler, and the overall aesthetics and softness of the textile product a1 are better.

[0131] Since the specific structure of the installation part a2 is diverse, the common structures are single-layer or double-layer fabric a4. The following are several examples to illustrate this.

[0132] In the first embodiment, as shown in Figures 7 and 8, the mounting portion a2 is a single-layer fabric layer, with at least a portion of the seam a6 passing through the core thread a7, and the seam a6 binding the core thread a7. The seam a6 not only passes through the mounting portion a2 but also through the core thread a7, thus making the core thread a7 more firmly bonded to the fabric layer, reducing the displacement of the core thread a7, and further improving the connection stability between the plastic chain tooth a3 and the mounting portion a2.

[0133] To further increase the connection stability between the plastic chain tooth a3 and the mounting part a2, as shown in Figure 8, a pre-drilled injection hole a5 is formed in the mounting part a2 by drilling. The plastic chain tooth a3 is installed in the mounting part a2 by injection molding and covers the pre-drilled injection hole a5 from top to bottom. Moreover, the plastic during injection passes through the pre-drilled injection hole a5 to form a connecting post a31 connecting the plastic chain tooth a3 located on the upper and lower sides of the mounting part a2.

[0134] The second embodiment, as shown in Figures 9 and 10, involves a concealed double-layer fabric structure a4 formed by stacking two single-layer fabrics. The double-layer fabric a4 includes an upper base fabric a41 and a lower base fabric a42. The edges of the upper base fabric a41 and the lower base fabric a42 are aligned vertically to form the mounting portion a2. A sewing thread a6 passes through the upper base fabric a41 and the lower base fabric a42. A core thread a7 is positioned on the outer edge of the lower base fabric a42, with at least a portion of the sewing thread a6 passing through the core thread a7, and the sewing thread a6 binding the core thread a7. The double-layer fabric a4 is formed by overlapping two independent single-layer fabrics with their edges aligned. Further, the two fabrics can be joined together using the sewing thread a6 or an adhesive layer. The lower base fabric a42 has two sides, with the side facing the upper base fabric a41 being the inner side and the opposite side being the outer side. In this embodiment, the core thread a7 is arranged on the outer side of the edge of the lower base fabric a42, and the core thread a7 is exposed on the side of the fabric a1 facing inward, thus not affecting the overall appearance of the fabric a1. Of course, in another equivalent embodiment, the core thread a7 can also be arranged at the outer edge of the double-layer fabric a4, and then the upper base fabric a41, the lower base fabric a42 and the core thread a7 are sewn together by the seam thread a6. In this case, the core thread a7 just covers the edge of the upper base fabric a41 and the lower base fabric a42 to form a more aesthetically pleasing edge finishing structure, and at the same time improves the connection stability of the plastic chain teeth a3.

[0135] The third embodiment, as shown in Figure 11, involves a concealed double-layer fabric structure a4 formed by folding a single layer of fabric inward. The double-layer fabric a4 includes an upper base fabric a41 and a lower base fabric a42. The folded edges of the upper and lower base fabrics a41 and a42 form the mounting portion a2. A stitch a6 passes through the upper and lower base fabrics a41 and a42. A core thread a7 is positioned on the outer edge of the lower base fabric a42, with a portion of the stitch a6 passing through and binding the core thread a7. The double-layer fabric a4 structure formed by folding a single layer of fabric inward offers better overall structural strength and aesthetics, which helps ensure the connection stability of the plastic chain teeth a3.

[0136] The fourth embodiment, as shown in Figure 12, involves a concealed double-layer fabric structure a4 formed by folding a single layer of fabric inward. The double-layer fabric a4 includes an upper base fabric a41 and a lower base fabric a42. The folded edges of the upper and lower base fabrics a41 and a42 form the mounting portion a2. A stitch a6 passes through the upper and lower base fabrics a41 and a42. A core thread a7 is positioned at the edge of the double-layer fabric a4 and is wrapped within it. Part of the stitch a6 is arranged along the side of the core thread a7. The function of the stitch a6 is to restrict the displacement of the core thread on the easily loosened side while sewing the upper and lower base fabrics a41 and a42 together, thereby improving the adhesion stability of the plastic chain teeth a3.

[0137] In this embodiment, the stitching method of the suture a6 can be flexibly arranged. In the first arrangement, part of the suture a6 only simultaneously passes through the upper base fabric a41, the core thread a7, and the lower base fabric a42 to achieve the stitching. In the second arrangement, after the suture a6 passes through the inner side of the core thread a7 of the upper base fabric a41 and the lower base fabric a42, part of the suture a6 extends from the outside of the upper base fabric a41 and the lower base fabric a42 to bind them together, thus achieving the stitching. This better defines the position of the core thread a7, making it less likely for the core thread a7 to detach from the double-layer fabric a4, further improving the adhesion stability of the plastic chain teeth a3.

[0138] A further technical solution, as shown in Figure 13, may include an intermediate adhesive layer a8, which is disposed within the double-layer fabric a4. The intermediate adhesive layer a8 is used to bond the upper base fabric a41 and the lower base fabric a42 together. When the core wire a7 is wrapped by the double-layer fabric a4, the intermediate adhesive layer a8 can simultaneously bond the upper base fabric a41, the lower base fabric a42, and the core wire a7, which further defines the position of the core wire a7.

[0139] A further technical solution could be, as shown in Figure 14, a waterproof membrane layer a9 is provided on the outer surface of the fabric layer at the installation location a2, and part of the waterproof membrane layer a9 is covered by the plastic chain teeth a3.

[0140] Previously, the manufacturing process for fabric products with injection-molded zipper teeth typically involved preparing a pair of specialized fabric strips, then using injection molding to attach the zipper teeth to the edges of the fabric strips to create a zipper tooth tape. Finally, the zipper tooth tape was sewn together with the fabric to produce the fabric product with injection-molded zipper teeth. The fabric strip became an essential component of zippered fabric products. However, to increase the bonding strength between the injection-molded zipper teeth and the fabric strip, the fabric strip was generally made of synthetic materials such as polyester fiber and nylon. This resulted in thick, hard, and rough surfaces with poor elasticity. Using such zipper tooth tape in some thin fabric products would significantly affect the softness and comfort of the fabric.

[0141] To address this, improvements have been made to the manufacturing process of zipper teeth and fabric products. For example, Chinese invention patent CN108402607B discloses a zippered product, zipper tooth components, and a method for manufacturing the zippered product. The zippered product has a pair of zipper tooth components, which are formed by installing zipper teeth onto a fixing component. The zipper-mounted component has a pair of tooth mounting edges at opposite positions for mounting the tooth components. The fixing component has a tooth retaining portion and an extension portion extending further along the length relative to the tooth retaining portion. The zipper tooth components are fixed to the tooth mounting edges of the zipper-mounted component by a sewing part for fixing the sewing thread, and the extension portion of the fixing component is fixed to the tooth mounting edges by the sewing part for fixing. This zipper tooth mounting method eliminates the need for fabric tape, but because both the sewing thread and the fixing component have a certain degree of elasticity, they are prone to deformation under stress, resulting in displacement between the zipper teeth and the zipper-mounted component, creating large gaps that are unsightly.

[0142] To further improve the bonding effect between the injection-molded chain teeth and the fabric of the product, and to avoid using a fabric tape as an intermediate component to further enhance the softness and comfort of the product, the applicant conceived of directly injection molding the chain teeth onto the fabric. However, existing injection-molded chain tooth technologies are all improvements based on the use of fabric tape, and there is no relevant technology applicable to directly injection molding chain teeth onto fabric. Therefore, through continuous technical experiments and improvements, the applicant has obtained the fabric product with plastic chain teeth proposed in this invention.

[0143] The structure of the fabric article equipped with plastic chain teeth, which applies the technical solution of the present invention, will be further described below with reference to the accompanying drawings.

[0144] Except where explicitly stated that they are equivalent or alternative implementation schemes, the various implementation details disclosed below may be selectively applied or combined in one embodiment even if they are not directly related or synergistic in terms of function.

[0145] Example 5

[0146] As shown in Figures 15-18, the fabric article b1 with plastic chain teeth proposed in this invention includes a concealed double-layer structure b4 formed by folding the fabric layers inward. The double-layer structure b4 includes an upper base fabric b41 and a lower base fabric b42. The folded edge area b2 of the double-layer structure b4 is used to install a plurality of spaced plastic chain teeth b3. It also includes a heat-adhesive film b21, which not only adheres to the inner edge area of ​​the lower base fabric b42 but also adheres to the upper base fabric b42. The base fabric b41 is used to achieve edge finishing at the junction of the upper base fabric b41 and the lower base fabric b42; injection molding pre-drilled holes b5 are formed by punching holes in the folded edge area b2 of the double-layer structure b4, and the plastic chain teeth b3 are installed in the folded edge area b2 of the double-layer structure b4 by injection molding and cover the injection molding pre-drilled holes b5 from top to bottom. Moreover, the plastic during injection molding passes through the injection molding pre-drilled holes b5 to form connecting posts b31 that connect the plastic chain teeth b3 located on the upper and lower sides of the double-layer structure b4.

[0147] As shown in Figures 15 and 16, which are simplified schematic diagrams of the cut pieces constituting the fabric item b1, the edge region of the double-layer structure b4 is the folded edge region b2. The folded edge region b2 can be directly placed in the injection molding equipment to injection mold the plastic chain teeth b3. To reduce the unraveling of the threads at the edges after the fabric is cut, the fabric of the fabric item b1 is trimmed by laser cutting, and then the inner edge region of the lower base fabric b42 is bonded to the upper base fabric b41 by the heat-bonding film b21. As shown in Figure 16, the double-layer structure b4 includes an upper base fabric b41 and a lower base fabric b42, wherein the lower base fabric b42 is an inwardly folded layer. Generally, the width of the lower base fabric b42 is greater than the width of the plastic chain teeth b3 covering the lower base fabric b42. By folding the edge area b2 where the plastic chain teeth b3 are installed, the depth of the injection-molded pre-drilled hole b5 is increased. Combined with the heat-adhesive film b21 bonding the upper and lower fabric layers, the thickness and hardness at the edge are locally strengthened. This improves the connection strength between the fabric of the textile b1 and the plastic chain teeth b3, and also enhances the ease of insertion and engagement of the zipper during use. Furthermore, since the folded edge area b2 uses the same fabric as the textile b1, there is no need to sew fabric tape, simplifying processing and improving the overall aesthetics of the textile b1.

[0148] As shown in Figures 17 and 18, the plastic chain tooth b3 includes an integrally formed main body b32 and chain tooth b33. The chain tooth b33 is connected to the side of the main body b32 and can form an engagement structure with other matching chain tooth b33. The main body b32 is used to connect with the folded edge region b2. The main body b32 includes an upper connecting part b321 and a lower connecting part b322. The connecting post b31 passes through the injection molding pre-set hole b5 and is connected to the upper connecting part b321 and the lower connecting part b322. In this way, the main body b32 and the chain tooth b33 of the plastic chain tooth b3 form a ring-shaped tight connection on the folded edge region b2 of the fabric b1. By laser-cutting the injection pre-drilled hole b5 on the double-layer structure b4, precise through holes can be made in the upper and lower layers of fabric so that the plastic chain tooth b3 can cover and form the connecting post b31 during injection molding. On the other hand, the upper and lower layers of fabric can be fused together to provide a stable connecting through hole for injection molding of the plastic chain tooth b3.

[0149] To enhance the connection stability between the plastic chain tooth b3 and the folded edge area b2 of the fabric b1, the adhesion effect of the plastic chain tooth b3 can be further improved based on the above embodiment one. The following are further explanations through several specific embodiments.

[0150] Example 6

[0151] As shown in Figures 19 and 20, the system also includes a stitching thread b6. The stitching thread b6 is arranged along the folded edge region b2 of the double-layer structure b4. The stitching thread b6 can pass through the upper base fabric b41 and the lower base fabric b42 of the double-layer structure b4, thereby sewing the two fabric layers together. The stitching thread b6 is arranged on the side of the injection molding pre-placed hole b5, and part of the stitching thread b6 is covered by the plastic chain teeth b3. The stitching thread b6 can be arranged on the inner or outer side of the injection molding pre-placed hole b5, so that the stitching thread b6 does not obstruct the injection molding pre-placed hole 5. Furthermore, the stitching method of the stitching thread b6 is relatively flexible. This embodiment uses a flat stitch, where the stitching thread b6 is arranged parallel to the folded edge of the double-layer structure b4. The stitching thread b6 can be a single thread or multiple threads arranged side by side. Of course, there are other stitching methods, such as the overlock stitching, where the stitching lines b6 are arranged in a crisscross pattern and wrap around a portion of the fabric near the folded edge of the double-layer structure b4, thus forming an overlock stitching structure. By setting the stitching lines b6, not only can the upper base fabric b41 and the lower base fabric b42 form a stable bond, but it can also form a concave-convex structure on the fabric, which helps to improve the bonding stability between the plastic chain teeth b3 and the folded edge area b2.

[0152] Example 7

[0153] As shown in Figures 21 and 24, the structure also includes a core thread b7. The core thread b7 is positioned at the folded edge region b2 of the double-layer structure b4 and is held between the upper base fabric b41 and the lower base fabric b42. At least one stitching line b6 extending along the length of the core thread b7 is arranged on the inner side region of the core thread b7, stitching the upper base fabric b41 and the lower base fabric b42 together. Parts of the stitching line b6 and the core thread b7 are covered by the plastic chain teeth b3. The inner side region of the core thread b7 refers to the area located next to the core thread b7 and away from the folded edge. Viewed from the front, this region is elongated and extends along the length of the core thread b7. Since the injection-molded pre-drilled hole b5 can be arranged on the inner or outer side of the stitching line b6, as in this embodiment, the injection-molded pre-drilled hole b5 is arranged on the side closer to the core wire b7. Thus, the injection-molded pre-drilled hole b5 passes through the upper base fabric b41 and the lower base fabric b42, and also partially passes through but does not break the core wire b7. Alternatively, the injection-molded pre-drilled hole b5 is arranged on the side farther from the core wire b7, and the injection-molded pre-drilled hole b5 only passes through the upper base fabric b41 and the lower base fabric b42. The stitching line b6 not only sews the upper base fabric b41 and the lower base fabric b42 but also restricts the displacement of the core wire b7 on the inner side, thereby improving the adhesion stability of the plastic chain teeth b3.

[0154] Example 8

[0155] As shown in Figures 23 and 24, the structure also includes a core wire b7. The core wire b7 is positioned at the folded edge region b2 of the double-layer structure b4 and is held between the upper base fabric b41 and the lower base fabric b42. A stitching thread b6 is provided at the location of the core wire b7. The stitching thread b6 is positioned outside the upper and lower base fabrics b41 and b42 and can pass through the inner side region of the core wire b7, thereby externally binding the core wire b7, the upper base fabric b41, and the lower base fabric b42. Part of the stitching thread b6 and the core wire b7 are covered by the plastic chain teeth b3. By binding the core wire b7, its position is better secured, preventing it from easily detaching from the double-layer structure b4, which improves the adhesion stability of the plastic chain teeth b3.

[0156] Based on this embodiment, a waterproof membrane layer b9 is also provided on the outer surface of the double-layer structure b4. The injection molding pre-placed hole b5 passes through the waterproof membrane layer b9, the stitching line b6 does not pass through the waterproof membrane layer b9, and part of the waterproof membrane layer b9 is covered by the plastic chain teeth b3.

[0157] Example 9

[0158] As shown in Figures 25 and 6, the fabric b1 further includes an intermediate adhesive layer b8, which is disposed in the double-layer structure b4. The double-layer structure b4 includes an upper base fabric b41 and a lower base fabric b42. The intermediate adhesive layer b8 is used to bond the upper base fabric b41 and the lower base fabric b42 together. The injection molding pre-set hole b5 formed by punching passes through the upper base fabric b41, the lower base fabric b42, and the intermediate adhesive layer b8. By setting the intermediate adhesive layer b8, the upper base fabric b41 and the lower base fabric b42 can be well bonded together without misalignment during laser processing, thus improving the stability of the processing position of the injection molding pre-set hole b5. In addition, adding the intermediate adhesive layer b8 in the middle of the double-layer structure b4 can appropriately increase the rigidity of the double-layer structure b4, which is beneficial to ensuring the smoothness of chain tooth engagement.

[0159] Example 10

[0160] As shown in Figures 27 and 28, based on Embodiment 5, a core wire b7 is also included. The core wire b7 is arranged in the folded edge region b2 of the double-layer structure b4 and is sandwiched between the upper base fabric b41 and the lower base fabric b42. The intermediate adhesive layer b8 can simultaneously bond the upper base fabric b41, the lower base fabric b42 and the core wire b7.

[0161] Example 11

[0162] As shown in Figures 29 and 30, based on Embodiment 6, a suture line b6 is also included. The suture line b6 is arranged along the extension direction of the core thread b7. The suture line b6 can pass through the upper base fabric b41 and the lower base fabric b42 of the double-layer structure b4 to sew the upper and lower fabric layers together. The suture line b6 is arranged on the side of the injection molding pre-placed hole b5, and part of the suture line b6 is covered by the plastic chain teeth b3. The intermediate adhesive layer b8 can simultaneously bond the upper base fabric b41, the lower base fabric b42, the core thread b7, and the suture line b6.

[0163] Example 12

[0164] As shown in Figures 31 and 32, based on embodiments five and six, a waterproof membrane layer b9 is further provided on the outer surface of the double-layer structure b4, and part of the waterproof membrane layer b9 is covered by the plastic zipper teeth 3. By providing the waterproof membrane layer b9, not only can the waterproof effect of the fabric be enhanced, but the folded edge area b2 can also be hardened to improve the convenience of using the zipper.
