Description

Technical Field

[0001] The invention relates to the technical field of nylon zippers, in particular to an anti-arching cloth tape, a nylon zipper and a processing technology thereof. Background Art

[0002] Zippers are a common closure device, widely used in clothing, bags, shoes, and other products. They consist of multiple components, each with a specific function, ensuring smooth opening and closing, and maintaining stability and durability during use. Zippers consist of a slider, teeth, and the fabric tape that secures the teeth. Nylon zippers are made from nylon monofilament, extracted from petroleum. After the nylon monofilament is spirally formed, the teeth and fabric tape are sewn together with thread to create a nylon zipper.

[0003] The existing publication, CN202980435U, describes a deformable zipper tape comprising a tape with chain elements mounted thereon. The tape includes a strip-shaped mounting portion, the edge of which connects to a deformable portion, upon which the chain elements are mounted. When the tape is installed in a corner structure, the deformable portion of the mesh fabric deforms, allowing the zipper to pass smoothly. The deformable zipper tape has a simple structure and is easy to implement, allowing the zipper to pass smoothly through corners, bringing greater convenience to the user and resolving a problem that has plagued the industry for years.

[0004] However, the above-mentioned nylon zipper tape has consistent texture, elasticity, and tightness in all areas. The fabric in the middle of the tape is relatively hard and does not have enough flexible space to be sewn with the clothing. Therefore, after the nylon zipper is sewn to the clothing, there will be varying degrees of arching, which affects the flatness and aesthetics of the entire garment. Summary of the Invention

[0005] The present invention solves the problems in the related art and provides an anti-arching cloth tape, a nylon zipper and a processing technology thereof.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: an anti-arching cloth tape, including a zipper strip, the zipper strip includes a core strip, an aluminum strip, a mesh and a reinforcing cloth, the core strip is made of hard rubber material, and an aluminum strip is provided through the inside of the core strip, and the aluminum strip and the core strip are integrally formed, meshes are horizontally provided on both sides of the core strip, and reinforcing cloth is provided on the outside of the core strip wrapped with the mesh, and the core strip, mesh and reinforcing cloth are fixedly connected by adhesive.

[0007] As a preferred solution, the mesh includes steel wire strips and plastic threads, the steel wire strips are used as weft yarns, the plastic threads are made of polyester fiber, and the plastic threads are used as warp yarns. The steel wire strips and the plastic threads are made into the mesh by plain weaving.

[0008] As a preferred solution, the reinforcing cloth is composed of nylon yarn and cotton yarn, with nylon yarn as weft yarn and cotton yarn as warp yarn, and the nylon yarn and cotton yarn are made into the reinforcing cloth by twill weaving.

[0009] As a preferred solution, the core strip, the mesh and the reinforcing cloth are bonded together by using chloroprene rubber glue.

[0010] A nylon zipper comprises a zipper strip, nylon sprockets, a stopper and a slider. Two zipper strips are symmetrically arranged, and nylon sprockets are horizontally fixed to the adjacent ends of the two zipper strips. Stoppers are fixed to the bottom ends of the two zipper strips, and sliders are installed on the nylon sprockets of the two zipper strips. The slider is used to engage or separate the nylon sprockets on the two zipper strips with each other. The zipper strips are made of anti-arching cloth tape.

[0011] As a preferred solution, a pulling hole is provided on the top surface of the slider, passing through the engagement grooves on both sides, and a pulling member is installed on the pulling hole.

[0012] As a preferred solution, the lifting member includes a stop column, two stop columns are symmetrically arranged, and the two stop columns slide through and are inserted into the pulling hole of the slider. The outer side of the two stop columns is vertically sleeved with a spring, and the two ends of the spring are respectively fixed on the top of the stop column and the top surface of the slider.

[0013] As a preferred solution, a rotating hole seat is vertically fixed to the top of the two stop columns, and a rotating column is horizontally arranged on the upper side of the rotating hole seat. A pull plate is vertically fixed to the upper part of the outer circumference of the rotating column, and the two ends of the rotating column are respectively rotatably connected to the rotating hole seats of the two stop columns, and a pinching plate is fixed to the top of the pull plate.

[0014] A nylon zipper processing process includes the following steps: S1. When producing zipper strips, first place two aluminum strips in a core strip forming mold made of hard rubber, then form the core strip and the two aluminum strips into one piece, then use a plain weave method to weave steel wire and plastic wire into a mesh, and finally use a twill weave method to weave nylon yarn and cotton yarn into a reinforcement cloth; S2, wrapping the core strip with a reinforcing cloth, and horizontally arranging meshes between the reinforcing cloth and the upper and lower end surfaces of the core strip, and then bonding the reinforcing cloth, the meshes and the core strip with an adhesive to form a zipper strip; S3. Installing nylon sprockets on the outer end surface of the zipper strip, and then fixing a stopper at the bottom end of the nylon sprocket, the stopper being fixed to the outer end surface of the zipper strip, and then installing a slider on the nylon sprocket, and the slider is used to engage or separate the nylon sprockets on the two zipper strips with each other; S4. A lifting piece is provided on the slider, and the stop post in the lifting piece is inserted into the lifting hole of the slider. The kneading plate in the slider is pulled to pull the rotating post at the bottom end of the pulling plate to deflect on the rotating hole seat of the stop post. When pulling, the lifting stop post slides in the lifting hole of the slider, and the stop post slides in the lifting hole to squeeze the spring deformation. The stop post is pulled out and is no longer stuck in the sprocket between the nylon sprockets. After the slider reaches a suitable height on the nylon sprocket, the pinching plate is released and the stop post is pushed to insert into the sprocket between the nylon sprocket under the action of the spring deformation force. The limit slider remains stable on the nylon sprocket to prevent the slider from slipping on the nylon sprocket in the future.

[0015] As a preferred solution, nylon chain teeth are sewn onto the sewing area of ​​the zipper tape to produce a nylon zipper.

[0016] Compared with the prior art, the present invention has the following beneficial effects: First, the core strip, mesh and reinforcing cloth are fixedly connected by adhesive. The core strip is made of neoprene hard rubber material. Neoprene has good weather resistance and fire resistance. At the same time, the neoprene hard rubber material is used as the core strip to improve the overall stiffness of the zipper strip. At the same time, the aluminum strip and the core strip are integrally formed and set. The aluminum strip serves as the keel of the core strip to improve the stiffness of the entire core strip. The reinforcing cloth is wrapped around the core strip, and mesh is horizontally set between the reinforcing cloth and the upper and lower end surfaces of the core strip. Then, the reinforcing cloth, mesh and core strip are bonded together by adhesive to form a zipper strip. Secondly, the plastic thread is made of polyester fiber, which has excellent elasticity and recovery, is easy to clean and dry, and is not easy to deform, thereby improving the overall stiffness of the zipper strip. The plastic thread is used as the warp, and the steel wire strips and the plastic thread are made into a mesh in a plain weave manner. The mesh made by the plain weave manner has a stable structure, is not easy to deform, and has a smooth fabric surface and good air permeability. The steel wire strips have high strength and are used as the thread to weave the mesh. The mesh serves as the external support surface of the zipper strip. The presence of the steel wire strips improves the overall stiffness of the zipper strip and reduces the arching of the zipper strip. Then, nylon yarn is light but extremely tough, has good waterproof performance, and is highly wrinkle-resistant, which improves the crispness of the zipper strip and avoids the arching of the zipper strip. At the same time, the cotton yarn is soft in texture, which improves the overall softness of the zipper strip. At the same time, nylon yarn and cotton yarn are made into a reinforced cloth using a twill weave. By staggering the yarns at a certain angle to form a diagonal pattern, the twill weave fabric is softer than the plain weave but equally strong, with better wear resistance and wrinkle resistance, and improves the crispness of the zipper strip. Finally, the core strip, mesh and reinforcing cloth are fixedly connected by adhesive. The core strip, mesh and reinforcing cloth use different structures and weaving processes to increase the stiffness between the core strip, mesh and reinforcing cloth, avoiding the arching phenomenon after the nylon zipper and anti-arching tape are sewn together, thereby improving the flatness and aesthetics of the entire garment.
