Description

Technical Field

[0001] The utility model relates to the technical field of zippers, and more particularly to a zipper and clothing. Background Art

[0002] The industry divides zippers into three categories according to the tooth material: nylon zippers, resin (plastic-steel) zippers, and metal zippers. Metal zipper teeth are made of copper or aluminum wire through a tooth arrangement machine, resin zipper teeth are made of polyester plastic rice through dye matching and arranged through an injection molding machine, and nylon zipper teeth are made of nylon monofilament wrapped around a center line through a heated mold.

[0003] Metal zippers are less commonly used due to their heavy weight and high cost. Resin zippers, made of polyoxymethylene (POM), are more suitable for applications requiring strong closing strength due to their high hardness and wear resistance. Nylon zippers are slightly less wear-resistant than resin zippers, but their flexibility gives them excellent bending and stretching properties, making them suitable for applications requiring high performance, such as outdoor sporting goods, specialty clothing, tents, and sleeping bags. Compared to metal and resin zippers, nylon zippers offer lower costs, higher production volumes, and a higher penetration rate.

[0004] CN213096483U This utility model relates to a wear-resistant zipper characterized by grooves on both the front and back surfaces of the left and right elements, each of which is secured to the fabric tape by sutures wound within the grooves. The grooves on both the front and back surfaces of the elements reduce friction between the sutures and the slider, thereby improving wear resistance. However, during the production of the elements, burrs are easily formed on the surface of the elements, which can scratch the fabric and wear the sutures.

[0005] Therefore, how to solve the problem that existing zippers easily scratch fabrics is a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0029] It should be noted that the directional words such as "up, down, left, right" below are defined based on the drawings in the specification.

[0030] The core of the present invention is to provide a zipper that can avoid notching the surface of the chain element 3, thereby preventing burrs from forming on the surface of the chain element 3, preventing the chain element 3 from scratching the fabric and wearing the seam line 2. Another core of the present invention is to provide a garment including the above-mentioned zipper, which can improve the user experience.

[0031] Please refer to Figure 1 and Figure 2 , a slide fastener includes a cloth tape 1.

[0032] Specifically, the cloth tape 1 includes at least a tooth sewing area and a main body area. The thickness of the tooth sewing area is less than that of the main body area. The tooth sewing area is provided with a groove 11 extending along its own length direction. The cloth tape 1 fixes the chain teeth 3 through the sewing thread 2, and the sewing thread 2 is wound around the chain teeth 3 and the groove 11. By providing the groove 11 on the cloth tape 1, the sewing thread 2 for fixing the chain teeth 3 can be completely accommodated in the groove 11 of the cloth tape 1, thereby avoiding the need to groove the chain teeth 3 to accommodate the sewing thread 2, and further avoiding the problem of scratching the fabric and wearing the sewing thread 2 caused by grooves on the chain teeth 3. The sewing thread 2 used to fix the chain teeth 3 is completely accommodated in the groove 11, which avoids the mutual friction between the inner cavity of the slider and the sewing thread 2 when the slider moves, and prevents the sewing thread 2 from pilling or breaking. It can not only improve the smoothness of the zipper, but also improve the wear resistance of the zipper, and extend the service life of the zipper. The cloth tape 1 is lighter and thinner than the conventional cloth tape 1.

[0033] The zipper arranged in the above manner forms a sewing groove 11 along the warp direction on the sewing side of the cloth tape 1 through process structure design, and the sewing thread 2 will be completely accommodated therein, effectively reducing the friction between the sewing thread 2 and the inner cavity of the slider, thereby improving the wear resistance and smoothness of the zipper, and at the same time avoiding grooving on the surface of the chain teeth 3, thereby avoiding the formation of burrs on the surface of the chain teeth 3, preventing the chain teeth 3 from scratching the fabric and wearing the sewing thread 2.

[0034] In the above embodiment, the weave structure of the fabric tape 1 is a twill weave, and the weave structure of the grooves 11 is a plain weave.

[0035] It should be noted that the fabric tape 1 is formed by a regular arrangement of two up and two down twill weaves and one up and one down plain weave in which the warp and weft yarns are not tightly interwoven. The twill weave and the plain weave are arranged into 6 groups of twill + 3 groups of plain weave + 2 groups of twill + 3 groups of plain weave + several twills on the sewing side of the fabric tape 1. The warp and weft yarns of the twill weave are looser than those of the plain weave, and at the same time, a longer weave point is formed on the surface of the fabric tape 1, which is slightly higher than the weave point formed by the plain weave, so that the weave point of the plain weave forms the groove 11 of the fabric tape 1.

[0036] The grooves 11 are directly formed on the front and back sides of the fabric tape 1 , and there is no restriction on the number of twill and plain weave groups corresponding to the fabric tape 1 and the grooves 11 .

[0037] In the above case, the depth and width of the groove 11 are not less than the diameter of the suture thread 2 .

[0038] It is understood that the width and depth of the groove 11 must be no less than the diameter of the suture 2 to completely prevent contact between the suture 2 and the inner side of the slider, thereby completely eliminating the adverse effects of friction between the suture 2 and the slider. When the slider moves, the suture 2 will not rub against the inner side of the slider, which not only prevents the suture 2 from fuzzing and thus does not adversely affect the smoothness of the zipper, but also prevents the suture 2 from breaking due to excessive friction, thereby improving the wear resistance of the zipper and extending its effective service life.

[0039] Furthermore, the cloth tape 1 includes a left cloth tape and a right cloth tape, and each of the left cloth tape and the right cloth tape is provided with at least two grooves 11 extending along its own length direction. The left cloth tape fixes the left link tooth through the left stitching line 2, and the right cloth tape fixes the right link tooth through the right stitching line 2. The left stitching line 2 is wound around the left link tooth and the corresponding groove 11, and the right stitching line 2 is wound around the right link tooth and the corresponding groove 11.

[0040] It should be noted that the left link tooth is fixed to the left cloth tape by the sewing thread 2, and the right link tooth is fixed to the right cloth tape by the sewing thread 2. The sewing thread 2 is wrapped around the outer surface of the link tooth 3 and the groove 11 of the cloth tape 1. The direction of the groove 11 is always consistent with the sewing direction of the sewing thread 2, so that the sewing thread 2 can always fall in the groove 11. When the slider moves, the sewing thread 2 will not rub against the inner side of the slider, avoiding the occurrence of fuzzing, and thus will not have an adverse effect on the smoothness of the slider movement, nor will the sewing thread 2 break due to excessive friction, thereby improving the wear resistance of the zipper and extending its effective service life.

[0041] In the above embodiment, the left link teeth are arranged in the same direction with equal intervals to form the left link belt, and the right link teeth are arranged in the same direction with equal intervals to form the right link belt. The left link teeth and the right link teeth are staggered, and the heads of the left link teeth and the right link teeth are provided with elliptical meshing parts, and the tails of the left link teeth and the right link teeth are provided with horizontal openings.

[0042] It is understood that the connection is achieved by the mutual engagement of the meshing portions of the left and right coupling teeth. The left and right coupling teeth are staggered to enable the mutual engagement of the meshing portions. The heads of the left and right coupling teeth are each provided with an elliptical meshing portion. The left and right coupling teeth are staggered so that the meshing portions of the two mesh with each other under the action of the slider, thereby achieving the closure of the zipper. The tails of the left and right coupling teeth are each provided with a horizontal opening, the depth of the opening being slightly greater than the thickness of the left and right fabric tapes. The left and right coupling teeth are both pressed onto the fabric tape 1 using a dedicated forming machine. During pressing, the opening is first inserted from the side of the left or right fabric tape so that the edge of the left or right fabric tape contacts the inner side of the opening. Then, pressure is applied along the upper and lower surfaces of the opening to close the opening and clamp the fabric tape 1. After pressing is completed, the left and right coupling teeth are secondary fixed using sutures 2 to further improve the installation security of the coupling teeth 3.

[0043] Based on the above embodiment, the lower end of the left chain is installed with a bottom stop, the upper end of the left chain is installed with a left top stop, the lower end of the right chain is installed with a latch, and the upper end of the right chain is installed with a right top stop.

[0044] It should be noted that in order to prevent the slider from falling off the left or right chain strap, a bottom stop is installed at the lower end of the left chain strap, and a left top stop is installed at the upper end of the left chain strap. At the same time, a pin used in conjunction with the bottom stop is installed at the lower end of the right chain strap, and a right top stop identical to the left top stop is installed at the upper end of the right chain strap.

[0045] In the above embodiment, a pull head is also included, which includes a pull tab, an upper plate and a lower plate. The pull tab is rotatably connected to the pull nose on the upper surface of the upper plate, and the upper plate and the lower plate are connected through the central top tongue on the front side.

[0046] It can be understood that an elliptical through hole is provided at one end of the pull tab to facilitate the control of the movement of the slider, and the other end of the pull tab is rotatably connected to the pull nose on the upper surface of the upper plate. The front area of ​​the upper plate and the lower plate is large, and the rear area is small, and the two are connected by the center top tongue on the front side. When the slider moves down, the center top tongue can be used to separate the engaged zipper, and when the slider moves up, the zipper can be engaged again.

[0047] As a preferred embodiment, the cloth tape 1 is interwoven with warp threads and weft threads, wherein the warp threads are 450D polyester DTY and the weft threads are 300D polyester DTY.

[0048] It should be noted that 450D polyester DTY is used as the warp and 300D polyester DTY is used as the weft. The width of the plain weave formed at the two needle insertion points is about 1 mm, which is the diameter of the groove 11 of the cloth tape 1. The width is slightly larger than the diameter of the suture line 2. From the cross-section, the suture line 2 is at most flush with the cloth tape 1.

[0049] In this embodiment, the diameter of the groove 11 is 1 mm. However, in practical applications, there is no limitation on the diameter of the groove 11 , as long as it is slightly larger than the diameter of the corresponding suture thread 2 .

[0050] In the above case, the zipper is a nylon zipper.

[0051] It can be understood that it has a certain degree of flexibility and good bending and stretching properties, and is suitable for various outdoor sports products, special clothing, tents, sleeping bags and other fields that require higher performance.

[0052] In summary, the zipper provided by the present invention forms a suture groove 11 along the warp direction on the sewing side of the cloth tape 1 through process structure design, and the suture thread 2 will be completely accommodated here, effectively reducing the friction between the suture thread 2 and the inner cavity of the slider, thereby improving the wear resistance of the zipper and improving the smoothness of the zipper. The thickness of the cloth tape 1 where the needle is inserted is 3-5 threads thinner than that of the non-insertion part. The reduced thickness can reduce the friction caused by the high-speed movement of the needle and the cloth tape 1 and reduce the fuzzing of the cloth tape 1.

[0053] In addition to the zippers disclosed in the above embodiments, the present invention also provides a garment including the above zippers. For the structures of other parts of the garment, please refer to the prior art and will not be described in detail herein.

[0054] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0055] The above describes in detail the zipper and garment provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are merely intended to facilitate understanding of the method and core concept of the present invention. It should be noted that those skilled in the art may make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications fall within the scope of protection of the claims of the present invention.
