Abstract
Description
Technical Field
[0001] This utility model belongs to the field of hook and loop fastener technology, and in particular relates to a metal wire hook and loop fastener structure. Background Technology
[0002] Velcro is a special adhesive material typically composed of two different fabrics: a "hook side" with small hooks and a "loop side" or "loop side" with small loops. When these two sides come into contact, the hooks catch the loops, forming a secure connection. Velcro is widely used in clothing, footwear, bags, toys, medical devices, and a wide variety of other products because it is easy to use and can be repeatedly fastened.
[0003] In existing technology, the hook side of hook and loop fasteners consists of a webbing strip with a plastic hook structure made of a high-hardness plastic material such as nylon on one side of the webbing strip; the loop side consists of a low-hardness polymer fiber material on one side of the webbing strip. Because hook and loop fasteners are repeatedly glued and removed, and because the rigidity and elasticity of the plastic hook have certain limitations, the hook portion of the hook side can deform or even straighten at the moment of separation from the loop side. After repeated use, the hook portion of the hook side will experience mechanical fatigue and lose its mechanical properties, resulting in the inability to hook and stick to the loop side. This leads to a poor lifespan after repeated use. Furthermore, since both the hook and loop sides are made of polymer materials, static electricity can be generated during the bonding and separation process, attracting dust and other problems. Utility Model Content
[0004] The purpose of this invention is to provide a metal wire hook and loop fastener structure to solve the problems of mechanical fatigue failure and static electricity caused by using plastic hooks on the hook side of hook and loop fasteners.
[0005] To achieve the above objectives, this utility model provides a metal wire hook and loop fastener structure, including a hook and loop fastener hook and loop structure. The hook and loop fastener hook and loop structure includes a webbing, and a plurality of metal wires are arranged on one side of the webbing. The metal wires have vertically extending free ends, and the free ends of the metal wires are provided with hooks. The hooks of the plurality of metal wires form a hook surface for attaching to the rough side of the hook and loop fastener.
[0006] Furthermore, the metal wire passes through the warp and / or weft yarns of the webbing and bends upward to form two vertically extending free ends, and the weft or warp yarns of the webbing fix the metal wire.
[0007] Furthermore, the metal wire is a steel wire; the diameter of the metal wire is 0.1 mm to 0.2 mm.
[0008] The above-mentioned one or more technical solutions in the hook and loop structure provided in this embodiment of the utility model have at least the following characteristics:
[0009] Furthermore, the hook and loop structure also includes a hook and loop pile structure, which includes a second webbing and flexible pile formed on one side of the second webbing. The flexible pile has an arched structure for engaging with the hook portion of the hook surface.
[0010] Furthermore, the flexible fleece is integrally woven with the second webbing.
[0011] Furthermore, the flexible fluff is formed by multiple warp yarns that are spaced apart and arched at intervals.
[0012] The above-described one or more technical solutions of the metal wire hook and loop fastener structure provided in this embodiment of the utility model have at least the following technical effects:
[0013] This utility model's metal wire hook and loop fastener structure features a metal wire on one side of the webbing. One end of the metal wire extends vertically, and its free end forms a hook, creating a hook surface on one side of the webbing. Due to the metal wire's excellent toughness and other mechanical properties, the hook can elastically deform and return to its original position when separated from the hook and loop fastener's surface. Even after repeated tearing and separation from the hook and loop fastener, it maintains good mechanical properties, effectively preventing failure, increasing the lifespan of the hook and loop fastener, and enhancing the adhesion between the hook surface and the surface. Furthermore, because the hook surface is made of metal wire, which prevents static electricity buildup, it effectively avoids static electricity issues with the hook and loop fastener, improving the user experience.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.
[0025] In one embodiment of the hook and loop fastener structure of this utility model, please refer to... Figure 1 and Figure 2The metal wire hook and loop fastener structure includes a hook and loop fastener hook surface structure and a hook and loop fastener loop surface structure that can be bonded to each other. The hook and loop fastener hook surface structure includes a webbing 100, on one side of which are arranged a plurality of metal wires 200. Each metal wire 200 has a vertically extending free end, and the free end of each metal wire 200 is provided with a hook portion 201. The hook portions 201 of the plurality of metal wires 200 form a hook surface 210 for bonding with the hook and loop fastener loop surface. (Refer to...) Figure 6 The hook and loop fastener structure includes a second webbing 400 and flexible pile 410 formed on one side of the second webbing 400. The flexible pile 410 has an arched structure for engaging with the hook portion 201 of the hook surface 210.
[0026] In this embodiment, the metal wire hook and loop fastener structure has a metal wire 200 on one side of the webbing 100. One end of the metal wire 200 extends vertically, and the free end of the metal wire 200 forms a hook portion 201, thereby forming a hook surface 210 on one side of the webbing. Because the metal wire has good toughness and other mechanical properties, when separated from the loop surface of the hook and loop fastener, the hook portion 201 can elastically deform and return to its original position. Even after repeated tearing from the loop surface of the hook and loop fastener, it can still maintain good mechanical properties, effectively avoiding failure and increasing the service life of the hook and loop fastener. It also increases the adhesion between the hook surface and the loop surface. Furthermore, since the hook surface is made of metal wire 200, which avoids the formation of static electricity, the problem of static electricity generation in the hook and loop fastener is effectively avoided, improving the user experience. Furthermore, since the hook and loop fastener's textured surface is formed with flexible pile 410 on one side of the second webbing 400, the strength of the flexible pile 410 is increased, avoiding breakage when separated from the hook surface. This not only ensures the adhesion between the hook surface and the textured surface but also increases the service life.
[0027] Furthermore, the metal wire 200 passes through the warp and / or weft yarns of the webbing 100 and bends upward to form two vertically extending free ends, with the weft or warp yarns of the webbing 100 fixing the metal wire 200. This allows the metal wire 200 to be more securely mounted on one side of the webbing 100.
[0028] Preferably, the metal wire 200 is steel wire or stainless steel wire. Steel wire and stainless steel have good toughness and elasticity, thus ensuring the service life of the metal wire 200. More preferably, the diameter of the metal wire 200 is 0.1 mm to 0.2 mm. Stainless steel wire has good anti-oxidation properties, increasing its service life. More preferably, the webbing 100 can be made of fire-retardant materials, such as aramid 1313, 1414, and other synthetic fibers, thus giving the hook-and-loop structure good fire resistance and corrosion resistance, allowing it to be used in special environments. Additionally, the pile structure that mates with the hook-and-loop structure can also use aramid 1313, aramid 1414, and other synthetic fibers as the base material of the webbing, and fire-retardant fine fibers as the pile surface.
[0029] Furthermore, the flexible pile 410 is woven integrally with the second webbing 400. This ensures that the flexible pile 410 is completely integrated with the second webbing 400, increasing strength and service life.
[0030] Furthermore, the flexible pile 410 is formed by multiple warp yarns that are spaced apart and arched at intervals.
[0031] The processing method of the hook and loop fastener surface in the above embodiment is specifically referred to... Figure 3 This includes the following steps:
[0032] Step 100: Several first yarns 1 and several metal wires 2 are taken as warp yarns, with the metal wires 2 and the first yarns 1 arranged alternately, and each metal wire 2 passing through a lifting device of the ribbon weaving machine (as shown in the attached figure); at least one second yarn 3 is taken as weft yarn. In this step, the ribbon weaving machine and the lifting device of the ribbon weaving machine are conventional technologies in the art, so their specific structure and working principle will not be described in detail in this embodiment.
[0033] Step 200: The weft yarn and the warp yarn are interwoven. During the interwoven process, the lifting device intermittently lifts the metal wire 2 upward, so that the metal wire 2 is intermittently interwoven with the weft yarn, forming a metal wire arch structure 20 on the woven tape 100. A bend 21 is formed at the top of the metal wire arch structure 20.
[0034] Step 300: Cut along the top of the arched structure 20 of the metal wire to form a hook in the bent part 21.
[0035] In this embodiment, the metal wire 2 is woven with the weft yarn to form a hook surface, which not only facilitates the forming of the metal wire and improves the forming efficiency, but also allows the metal wire to form a whole with the webbing.
[0036] Furthermore, a slurry coating and curing step is provided between step 200 and step 300 to increase the strength of the webbing 100 and make the webbing 100 and the metal wire 2 more secure and stable.
[0037] Furthermore, refer to Figure 3 and Figure 4 The weaving machine is also equipped with multiple spacers 4. A lifting device lifts the metal wire 2 and moves it back and forth on both sides of the spacers 4, causing the lifting device to drive the metal wire 2 to wrap around the spacers 4. The top side of the spacers 4 is used to form and shape the bent portion 21 of the metal wire 2. In this embodiment, the lifting device can move laterally, causing it to drive the metal wire 2 to move back and forth on both sides of the spacers 4 and weave with the weft yarn. The spacers 4 support the woven metal wire 2, allowing it to be shaped by the spacers 4.
[0038] Furthermore, refer to Figure 3 The spacer 4 extends along the length of the front of the weaving machine, ensuring that the woven metal wire 2 remains supported on the spacer 4. Therefore, the spacer 4 continuously supports and shapes the arched structure 20 of the metal wire, thereby increasing the stability of the bent portion 21 after bending.
[0039] Furthermore, step 300 includes a shearing device 300, which shears the arched structure 20 of the metal wire 2. Specifically, refer to... Figure 5 The shearing device 300 includes a carrier plate 310, scissors 320, and a conveying mechanism 330. The conveying mechanism 330 is located on one side of the carrier plate 310 for conveying the webbing. The scissors 320 is located on the other side of the carrier plate 310, and a guide groove 301 is formed between the scissors 320 and the carrier plate 310, through which the webbing passes. The scissors 320 includes a fixed blade 321, a movable blade 322, and a driving member 323. The movable blade 322 and the fixed blade 321 are stacked on top of each other. The driving member 323 is connected to the movable blade 322 and is used to drive the movable blade 322 to reciprocate. The ends of the movable blade 322 and the fixed blade 321 are provided with serrated cutting edges facing the guide groove 301. The webbing passing through the guide groove 301 causes the metal wire arch structure 20 to face the cutting edges. The movable blade 322 and the fixed blade 321 move alternately to cut the metal wire arch structure 20 along the bend 21.
[0040] Furthermore, the opening of the guide groove 301 faces upward, forming a corner position for the webbing on the side of the carrier plate 310. The webbing turns at the corner position, causing the metal wire arching structure 20 at the corner position to face the cutting edge. This facilitates the shearing device 300 to cut the metal wire arching mechanism 20 along the bend 21.
[0041] Furthermore, the webbing machine also incorporates a baking device that radiates heat to the webbing, causing the first yarn 1 and the second yarn 3 to shrink and set, thus fixing the metal wire 2. Specifically, the baking device can be a heat radiation lamp.
[0042] This utility model also provides a method for producing metal wire hook and loop fasteners. The only difference between the processing method of the hook and loop fastener hook and loop structure in the above embodiments is that flexible fibers are used to replace the metal wire 2, and there is no need to cut off the woven arched part, so that the hook and loop fastener hook and loop structure can be woven and formed.
[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
