AI Technical Summary
When installing zipper teeth on existing garments, the core thread is prone to loosening, resulting in insecure zipper teeth and affecting the normal opening and closing of the zipper pull. Furthermore, existing injection-molded zipper tooth technology is mostly based on fabric tape, which cannot be directly injected into the fabric, affecting production efficiency and softness and comfort.
By sewing a core thread along the edge of the fabric and fixing it with the seam, a chain tooth fixing part is formed. Plastic chain teeth are directly injection molded onto the double-layer fabric, and the connection stability is improved by combining a heat-bonded film and a sewing thread. Alternatively, core threads and seams can be arranged at the installation location to fix the plastic chain teeth.
It improves the installation stability and firmness of chain teeth, simplifies the production process, enhances the aesthetics and softness of fabric products, and extends their service life.

Technical Field
[0003] This application belongs to the technical field of clothing, specifically relating to a garment with 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] 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.
[0007] To solve the above-mentioned technical problems, this application is implemented as follows:
[0008] This application provides a garment with chain teeth, including: fabric, core thread, sewing thread, and multiple chain teeth;
[0009] The fabric has an edge portion, and the core yarn contacts the edge portion and extends along the edge portion;
[0010] 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;
[0011] 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.
[0012] 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.
[0013] 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. The fabric product includes a hidden double-layer structure formed by folding the fabric layers inward. The double-layer structure includes an upper base fabric and a... The lower base fabric; the folded edge area of the double-layer structure is used to install multiple plastic chain teeth arranged at intervals; characterized in that it further includes a heat-adhesive film, which not only adheres to the inner edge area of the lower base fabric but also adheres to the upper base fabric to achieve edge finishing at the junction of the upper and lower base fabrics; injection molding pre-set holes are formed in the folded edge area of the double-layer structure by punching holes, and the plastic chain teeth are installed in the folded edge area of the double-layer structure by injection molding and cover the injection molding pre-set holes from top to bottom, and the plastic during injection molding passes through the injection molding pre-set holes to form connecting posts connecting the plastic chain teeth located on the upper and lower sides of the double-layer structure.
[0014] 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.
[0015] 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.
[0016] 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.
[0017] 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.
[0018] According to the above technical solution, compared with the prior art, the beneficial technical effects of the present invention are as follows: First, by folding the folded edge area where the plastic chain teeth are installed, a double-layer structure is formed in the folded edge area, increasing the depth of the injection molding pre-set hole. Combined with the heat-adhesive film bonding the upper and lower fabric layers, the thickness and hardness at the edge can be locally strengthened. This is beneficial to improving the connection strength between the fabric of the textile and the plastic chain teeth, and also beneficial to improving the convenience of insertion and engagement of the zipper during use. Second, since the folded edge area uses the same fabric as the textile, there is no need to sew fabric tape, making the processing simpler, and the overall aesthetics and softness of the textile are better. Third, by laser-cutting the injection molding pre-set hole on the double-layer structure, on the one hand, precise through holes can be opened on the upper and lower fabric layers so that the plastic chain teeth can be covered to form a connecting post during injection molding; on the other hand, the upper and lower fabric layers can be fused together, providing a stable connecting through hole for injection molding the plastic chain teeth.
[0019] A further technical solution may include a suture thread 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-drilled 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 line or multiple lines arranged side by side; the second is a lockstitch, 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, thus forming a lockstitch structure. By setting the suture thread, a concave-convex structure can be formed on the fabric, which helps to improve the adhesion of the plastic chain teeth. The suture thread is arranged on the side of the injection molding pre-drilled hole, but it is not limited to being arranged specifically inside or outside the injection molding pre-drilled hole, so that the suture thread does not obstruct the injection molding pre-drilled hole.
[0020] However, by installing the plastic chain teeth after arranging the sutures, the bonding force between the plastic chain teeth and the folded edge area can be improved by means of the sutures, thereby improving the connection stability of the plastic chain teeth.
[0021] 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. In this way, the suture not only connects the upper and lower base fabrics but also restricts the displacement of the core on the inside, which helps to improve the adhesion stability of the plastic chain teeth.
[0022] A further technical solution may 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. A stitching thread is positioned at the core wire's location, positioned outside the upper and lower base fabrics and able to pass through them from the inner side region of the core wire, thereby externally binding the core wire, upper base fabric, and lower base fabric. Part of the stitching thread and core wire are covered by the plastic chain teeth. Binding the core wire with the stitching thread better defines its position, preventing it from easily detaching from the double-layer structure and further improving the adhesion stability of the plastic chain teeth.
[0023] 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.
[0024] A further technical solution may include an intermediate adhesive layer disposed within the double-layer structure, which comprises an upper base fabric and a lower base fabric. The intermediate adhesive layer is used to bond the upper and lower base fabrics together. The injection-molded pre-drilled hole formed by the punching penetrates the upper base fabric, the lower base fabric, and the intermediate adhesive layer. By providing the intermediate adhesive layer, the upper and lower base fabrics can be well bonded together without misalignment during punching, improving the stability of the processing position of the injection-molded pre-drilled hole. Furthermore, adding the intermediate adhesive layer in the middle of the double-layer structure can appropriately increase the rigidity of the double-layer structure, which is beneficial for ensuring smooth engagement of the chain teeth.
[0025] 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. Further, it may include a stitching thread, which is arranged along the extension direction of the core wire. The stitching thread can pass through the upper and lower base fabrics of the double-layer structure to sew the two fabric layers together. The stitching thread is arranged on the side of the injection molding pre-set hole, and part of the stitching 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 stitching thread. Further, 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. The core wire can locally increase the protrusion height of the folded edge area to improve the adhesion of the plastic chain teeth.
[0026] Because of the above-mentioned features and advantages, this invention can be applied to textile products equipped with plastic chain teeth.
[0027] 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. Therefore, through continuous technical experiments and improvements, the applicant has obtained the fabric product with directly installed plastic chain teeth proposed in this invention. The fabric product includes an installation part for installing plastic chain teeth and multiple plastic chain teeth installed in the installation part in a gap manner. The feature is that a core thread and a sewing thread are arranged in the installation part, the sewing thread is inserted into the installation part, the core thread is positioned in the installation part through the sewing thread, and the plastic chain teeth are installed in the installation part by injection molding and simultaneously bite the core thread and the sewing thread.
[0028] 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.
[0029] 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.
[0030] According to the above technical solution, compared with the prior art, the beneficial technical effects of the present invention are as follows: First, by arranging the core wire at the edge of the mounting part and fixing the core wire stably at the edge by the sewing thread, the thickness of the edge part can be increased. After the plastic chain teeth are injection molded, they can bite the core wire and the sewing thread, thereby improving the connection stability between the plastic chain teeth and the mounting part and greatly improving the service life of the fabric product; Second, since the mounting part uses the same fabric as the fabric product, there is no need to sew fabric tape, making the processing simpler and the overall aesthetics and softness of the fabric product better.
[0031] The specific structure of the installation part is flexible and varied. The following describes several specific implementation methods.
[0032] 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, thus firmly bonding the core thread to the fabric layer, reducing core thread displacement, and further improving the connection stability between the plastic chain teeth and the mounting portion.
[0033] Based on this embodiment, in order to further increase the connection stability between the plastic chain teeth and the mounting part, injection pre-drilled holes are formed in the mounting part by drilling. The plastic chain teeth are installed in the mounting part 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 connecting the plastic chain teeth located on the upper and lower sides of the mounting part.
[0034] 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.
[0035] 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.
[0036] The fourth embodiment utilizes a concealed 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 portions. The stitching passes through the upper and lower base fabrics. The core thread is positioned at the folded edges of the double-layer fabric and is wrapped within it. Part of the stitching is arranged along the side of the core thread. The function of the stitching is to restrict the displacement of the core thread from the side while sewing the upper and lower base fabrics together. This effectively reduces core thread displacement, thereby improving the adhesion stability of the plastic chain teeth.
[0037] In addition to the fourth embodiment, some of the stitches simultaneously pass through the upper base fabric, the core thread, and the lower base fabric.
[0038] Alternatively, some of the stitching may be used to bind the upper base fabric, core thread, and lower base fabric together from the outside of the upper and lower base fabrics. This better secures the position of the core thread, making it less likely to detach from the double-layer fabric and further improving the adhesion stability of the plastic chain teeth.
[0039] 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.
[0040] 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.
[0041] Because of the above-mentioned features and advantages, this invention can be applied to textile products with directly installed plastic chain teeth. Attached Figure Description

[0081] 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.
[0082] 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.
[0083] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.
[0084] Referring to Figures 1 to 12, this application discloses a garment with chain teeth 40. The disclosed garment includes fabric 10, core thread 20, stitching thread 30, and multiple chain teeth 40.
[0085] 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.
[0086] 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.
[0087] 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.
[0088] 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.
[0089] 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.
[0090] 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.
[0091] 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.
[0092] 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.
[0093] The relative positional relationship between core wire 20 and the edge will be explained in detail below, including:
[0094] In the first embodiment, the core wire 20 is located inside the edge portion.
[0095] Referring to Figure 7, the edge region of the fabric 10 can adopt a folding structure 10a, which includes a fabric body 11, a folded edge 12, and a connecting portion 13. The folded edge 12 is attached to the edge surface of the fabric body 11, and a fitting area N is formed 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.
[0096] 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.
[0097] 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.
[0098] 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.
[0099] 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.
[0100] 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.
[0101] 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.
[0102] 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.
[0103] Furthermore, the sewing thread 30 can sew the core thread 20 and the folded structure 10a to improve the stability of the core thread 20. Optionally, as shown in Figure 7, 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, a portion of the edge area is folded over 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.
[0104] 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.
[0105] 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.
[0106] In the second embodiment, the core wire 20 is located outside the edge portion.
[0107] 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.
[0108] 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.
[0109] 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.
[0110] 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.
[0111] 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.
[0112] 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.
[0113] 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.
[0114] Referring to Figures 10 to 12, in some embodiments, the edge region of the fabric 10 may employ a planar extension structure 10b, that is, 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.
[0115] Referring to Figures 1 to 6 and 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 hem 12, and a connecting portion 13. The hem 12 adheres to the edge surface of the fabric body 11, forming a fitting area N between the hem 12 and the fabric body 11. The connecting portion 13 connects the edge end of the hem 12 and the edge end of the fabric body 11. Furthermore, the area of the hem 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 hem 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 hem 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.
[0116] 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.
[0117] Referring to Figure 6, to further limit 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.
[0118] 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.
[0119] Referring again 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.
[0120] 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.
[0121] 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.
[0122] 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.
[0123] 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.
[0124] 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.
[0125] 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.
[0126] 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.
[0127] In some embodiments, the chain teeth 40 may be connected to the chain tooth fixing part by snap-fit or injection molding.
[0128] 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.
[0129] 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.
[0130] 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.
[0131] Optionally, the chain tooth 40 can be a metal chain tooth or a plastic chain tooth.
[0132] 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.
[0133] 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.
[0134] 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.
[0135] 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.
[0136] 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.
[0137] In addition, the connecting hole can also be a hot melt hole formed during the hot melting process.
[0138] In some embodiments, fabric 10 may be a single-layer fabric; of course, fabric 10 may also be a multi-layer fabric.
[0139] 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.
[0140] 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.
[0141] 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.
[0142] 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.
[0143] 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.
[0144] The following examples will illustrate the connection relationship between the core thread 20, the sewing thread 30, and the fabric 10:
[0145] Referring to Figure 4, the core thread 20 is located on the side surface of the connecting portion 13 away from the folded edge 12 and the fabric body 11, so as to support and limit the core thread 20 through this surface; and the core thread 20 and the connecting portion 13 are sewn together with the sewing thread 30 to ensure a reliable connection between the core thread 20 and the connecting portion 13 and to prevent the core thread 20 from moving at will.
[0146] It should be noted that in this method, a portion of the sewing thread 30 is located on the inner surface of the connecting part 13. To sew the sewing thread 30, as shown in Figure 3, the fabric 10 is first 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 then sewn together using 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.
[0147] Referring to Figure 5, 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; and, the core threads 20 and the folded edge 12 and the fabric body 11 are sewn together with the 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.
[0148] 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.
[0149] Referring 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.
[0150] 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.
[0151] Referring to Figure 9, a core thread 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 thread 20 through one side surface of the connecting part 13.
[0152] 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.
[0153] Referring to Figures 10 to 12, the two core wires 20 are in contact with the opposite sides of the planar extension structure 10b, so as to support and limit the core wires 20 at the corresponding positions through the opposite sides of the planar extension structure 10b.
[0154] 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.
[0155] 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.
[0156] 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.
[0157] 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 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 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, causing displacement between the zipper teeth and the zipper-mounted component, resulting in large gaps that are unsightly.
[0158] 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.
[0159] 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.
[0160] Example 1
[0161] As shown in Figures 13-16, the fabric article 1 with plastic chain teeth proposed in this invention includes a hidden double-layer structure 4 formed by folding the fabric layers inward. The double-layer structure 4 includes an upper base fabric 41 and a lower base fabric 42. The folded edge area 2 of the double-layer structure 4 is used to install a plurality of spaced plastic chain teeth 3. It also includes a heat-adhesive film 21, which not only adheres to the inner edge area of the lower base fabric 42 but also adheres to the upper base fabric 41, thereby achieving edge finishing at the junction of the upper base fabric 41 and the lower base fabric 42. Injection molding pre-set holes 5 are formed by punching holes in the folded edge area 2 of the double-layer structure 4. The plastic chain teeth 3 are installed in the folded edge area 2 of the double-layer structure 4 by injection molding and cover the injection molding pre-set holes 5 from top to bottom. Moreover, the plastic during injection molding passes through the injection molding pre-set holes 5 to form connecting posts 31 connecting the plastic chain teeth 3 located on the upper and lower sides of the double-layer structure 4.
[0162] As shown in Figures 13 and 14, which are simplified schematic diagrams of the cut pieces constituting the fabric 1, the edge region of the double-layer structure 4 is the folded edge region 2, which can be directly placed in the injection molding equipment to injection mold the plastic chain teeth 3. To reduce the unraveling of the threads at the edges after the fabric is cut, the fabric of the fabric 1 is trimmed by laser cutting, and then the inner edge region of the lower base fabric 42 is bonded to the upper base fabric 41 by the heat-bonding film 21. As shown in Figure 14, the double-layer structure 4 includes an upper base fabric 41 and a lower base fabric 42, wherein the lower base fabric 42 is an inwardly folded layer, and generally the width of the lower base fabric 42 is greater than the width of the plastic chain teeth 3 covering the lower base fabric 42. By folding the edge area 2 where the plastic chain teeth 3 are installed, the depth of the injection-molded pre-drilled hole 5 is increased. Combined with the heat-adhesive film 21 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 1 and the plastic chain teeth 3, and also enhances the ease of insertion and engagement of the zipper during use. Furthermore, since the folded edge area 2 uses the same fabric as the textile 1, there is no need to sew fabric tape, simplifying processing and improving the overall aesthetics of the textile 1.
[0163] As shown in Figures 15 and 16, the plastic chain tooth 3 includes an integrally formed main body 32 and chain tooth 33. The chain tooth 33 is connected to the side of the main body 32 and can form an engagement structure with other mating chain teeth 33. The main body 32 is used to connect with the folded edge region 2. The main body 32 includes an upper connecting part 321 and a lower connecting part 322. The connecting post 31 passes through the injection molding pre-drilled hole 5 and is connected to the upper connecting part 321 and the lower connecting part 322. In this way, the main body 32 and the chain tooth 33 of the plastic chain tooth 3 form a ring-shaped tight connection on the folded edge region 2 of the fabric 1. By laser-cutting the injection molding pre-drilled hole 5 on the double-layer structure 4, precise through holes can be opened in the upper and lower layers of fabric so that the plastic chain tooth 3 can cover the connecting post 31 during injection molding. On the other hand, the upper and lower layers of fabric can be fused together, providing a stable connecting through hole for injection molding of the plastic chain tooth 3.
[0164] In order to enhance the connection stability between the plastic chain teeth 3 and the folded edge area 2 of the fabric 1, the adhesion effect of the plastic chain teeth 3 can be enhanced by further improvements based on the above embodiment 1. The following are further explanations through several specific embodiments.
[0165] Example 2
[0166] As shown in Figures 17 and 18, the structure also includes a stitching thread 6. The stitching thread 6 is arranged along the folded edge region 2 of the double-layer structure 4. The stitching thread 6 can pass through the upper base fabric 41 and the lower base fabric 42 of the double-layer structure 4 to sew the two fabric layers together. The stitching thread 6 is arranged on the side of the injection molding pre-drilled hole 5, and part of the stitching thread 6 is covered by the plastic chain teeth 3. The stitching thread 6 can be arranged on the inner or outer side of the injection molding pre-drilled hole 5, so that the stitching thread 6 does not obstruct the injection molding pre-drilled hole 5. Furthermore, the stitching method of the stitching thread 6 is relatively flexible. This embodiment uses a flat stitch, where the stitching thread 6 is arranged parallel to the folded edge of the double-layer structure 4. The stitching thread 6 can be a single thread or multiple threads arranged side by side. Of course, there are other stitching methods, such as a serged edge stitch, where the stitching thread 6 is arranged in a crisscross pattern and wraps around a portion of the fabric of the double-layer structure 4 near the folded edge, thereby forming a serged edge structure. By setting the stitching line 6, not only can the upper base fabric 41 and the lower base fabric 42 form a stable bond, but it can also form a concave-convex structure on the fabric, which is beneficial to improving the bonding stability between the plastic chain teeth 3 and the folded edge area 2.
[0167] Example 3
[0168] As shown in Figures 19 and 20, the structure also includes a core thread 7. The core thread 7 is arranged in the folded edge region 2 of the double-layer structure 4 and is held between the upper base fabric 41 and the lower base fabric 42 of the double-layer structure 4. At least one stitching line 6 extending along the length of the core thread 7 is arranged in the inner side region of the core thread 7. The stitching line 6 sews the upper base fabric 41 and the lower base fabric 42 together. Part of the stitching line 6 and the core thread 7 are covered by the plastic chain teeth 3. The inner side region of the core thread 7 refers to the region located next to the core thread 7 and away from the folded edge. From the front, this region is elongated and extends along the length of the core thread 7. Since the injection molding pre-placed hole 5 can be arranged on the inner or outer side of the stitch line 6, as in this embodiment, the injection molding pre-placed hole 5 is arranged on the side close to the core wire 7, so that the injection molding pre-placed hole 5, in addition to passing through the upper base fabric 41 and the lower base fabric 42, also partially passes through but does not break the core wire 7.
[0169] Of course, in another case, the injection molding pre-drilled hole 5 is arranged on the side away from the core wire 7, and the injection molding pre-drilled hole 5 only passes through the upper base fabric 41 and the lower base fabric 42. The stitching line 6 not only sews the upper base fabric 41 and the lower base fabric 42, but also restricts the displacement of the core wire 7 on the inside, thereby improving the adhesion stability of the plastic chain teeth 3.
[0170] Example 4
[0171] As shown in Figures 21 and 22, the structure also includes a core wire 7. The core wire 7 is positioned at the folded edge region 2 of the double-layer structure 4 and is held between the upper base fabric 41 and the lower base fabric 42. A stitch 6 is provided at the location of the core wire 7. The stitch 6 is positioned outside the upper base fabric 41 and the lower base fabric 42 and can pass through the upper base fabric 41 and the lower base fabric 42 from the inner side region of the core wire 7, thereby externally binding the core wire 7, the upper base fabric 41, and the lower base fabric 42. Part of the stitch 6 and the core wire 7 are covered by the plastic chain teeth 3. By binding the core wire 7, its position is better secured, preventing it from easily detaching from the double-layer structure 4, which improves the adhesion stability of the plastic chain teeth 3.
[0172] Based on this embodiment, a waterproof membrane layer 9 is also provided on the outer surface of the double-layer structure 4. The injection molding pre-placed hole 5 passes through the waterproof membrane layer 9, the stitching line 6 does not pass through the waterproof membrane layer 9, and part of the waterproof membrane layer 9 is covered by the plastic chain teeth 3.
[0173] Example 5
[0174] As shown in Figures 23 and 24, the fabric product 1 further includes an intermediate adhesive layer 8, which is disposed in the double-layer structure 4. The double-layer structure 4 includes an upper base fabric 41 and a lower base fabric 42. The intermediate adhesive layer 8 is used to bond the upper base fabric 41 and the lower base fabric 42 together. The injection molding pre-placed hole 5 formed by punching passes through the upper base fabric 41, the lower base fabric 42, and the intermediate adhesive layer 8. By setting the intermediate adhesive layer 8, the upper base fabric 41 and the lower base fabric 42 can be well bonded together without misalignment during laser processing, thus improving the stability of the processing position of the injection molding pre-placed hole 5. In addition, adding the intermediate adhesive layer 8 in the middle of the double-layer structure 4 can appropriately increase the rigidity of the double-layer structure 4, which is beneficial to ensuring the smoothness of chain tooth engagement.
[0175] Example 6
[0176] As shown in Figures 25 and 26, based on Embodiment 5, a core wire 7 is also included. The core wire 7 is arranged in the folded edge region 2 of the double-layer structure 4 and is sandwiched between the upper base fabric 41 and the lower base fabric 42. The intermediate adhesive layer 8 can simultaneously bond the upper base fabric 41, the lower base fabric 42 and the core wire 7.
[0177] Example 7
[0178] As shown in Figures 27 and 28, based on Embodiment 6, a suture 6 is also included. The suture 6 is arranged along the extension direction of the core thread 7. The suture 6 can pass through the upper base fabric 41 and the lower base fabric 42 of the double-layer structure 4 to sew the upper and lower fabric layers together. The suture 6 is arranged on the side of the injection molding pre-placed hole 5, and part of the suture 6 is covered by the plastic chain teeth 3. The intermediate adhesive layer 8 can simultaneously bond the upper base fabric 41, the lower base fabric 42, the core thread 7, and the suture 6.
[0179] Example 8
[0180] As shown in Figures 29 and 30, based on embodiments five and six, a waterproof membrane layer 9 is further provided on the outer surface of the double-layer structure 4, and part of the waterproof membrane layer 9 is covered by the plastic zipper teeth 3. By providing the waterproof membrane layer 9, not only can the waterproof effect of the fabric be enhanced, but the folded edge area 2 can also be hardened to improve the convenience of using the zipper.
[0181] As shown in Figures 31 to 34, 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.
[0182] 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 stitching 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 stitching 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.
[0183] 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 some examples to illustrate this.
[0184] In the first embodiment, as shown in Figures 31 and 32, 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.
[0185] To further increase the connection stability between the plastic chain tooth A3 and the mounting part A2, as shown in Figure 32, 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.
[0186] The second embodiment, as shown in Figures 33 and 34, 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 stitch 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 stitch A6 passing through the core thread A7, and the stitch A6 also binds the core thread A7. The double-layer fabric A4 is formed by overlapping two independent single-layer fabrics with their edges aligned. Alternatively, the two fabrics can be joined together using the stitch 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 also improves the connection stability of the plastic chain teeth A3.
[0187] The third embodiment, as shown in Figure 35, involves a concealed double-layer fabric A4 structure 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 strength and aesthetics, which helps ensure the connection stability of the plastic chain teeth A3.
[0188] The fourth embodiment, as shown in Figure 36, 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.
[0189] 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.
[0190] A further technical solution, as shown in Figure 37, 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.
[0191] A further technical solution could be, as shown in Figure 38, 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.

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.
