Description

Technical Field

[0001] This utility model relates to the field of zippers, and in particular to a zipper tape and a zipper. Background Technology

[0002] A zipper consists of a zipper pull and two single-sided chain teeth. Each single-sided chain tooth includes a fabric strip and teeth attached to the strip. When a zipper is sewn to clothing, the edge of the fabric strip furthest from the teeth is sewn to the inside of the garment, which may touch the user, causing discomfort. Furthermore, the exposed edge of the fabric strip is unsightly. To address this, two methods are generally used to improve both appearance and feel. The first method involves adding binding tape to the edge of the fabric strip furthest from the teeth, sewing the binding tape to the fabric. However, this increases material costs and the number of stitches required. The second method involves folding the edge of the fabric strip furthest from the teeth upwards to create a folded structure. While this method reduces the number of stitches and results in a cleaner, more aesthetically pleasing appearance, it requires specialized tools and is more difficult to sew than a regular fabric strip. In addition, since users will touch the edge of the tape away from the chain teeth, this edge needs to be flexible; while the part of the tape that is not sewn to the fabric needs to be tough.

[0003] Designing a fabric tape structure that allows for flexibility on the side of the tape away from the chain teeth while maintaining strength on the unsewn portion, while minimizing sewing difficulty and the number of sewing operations, is a problem that needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a zipper tape and zipper that can make the edge of the tape away from the chain teeth soft and the part of the tape not sewn to the sewn part tough, with low sewing difficulty and fewer sewing times.

[0005] To solve the above-mentioned technical problems, this utility model provides a zipper tape, comprising: a zipper tooth sewing part, a body part, and a binding part arranged sequentially along the width direction; the zipper tooth sewing part is used to connect the zipper teeth; the binding part is used to connect the sewn part; the binding part has a double-layer structure; the warp density of the body part is greater than the warp density of the binding part.

[0006] In the zipper tape of this utility model, since the chain tooth sewing part, the body part, and the binding part are arranged sequentially, the binding part is directly set on the zipper tape, which reduces the sewing difficulty and the number of sewing steps; the binding part has a double-layer structure, which facilitates the sewing of the part to be sewn onto the binding part; since the warp density of the body part is relatively high, the body part has good toughness; since the warp density of the binding part is relatively low, the binding part has good softness and achieves lightweighting.

[0007] Preferably, the width of the binding portion is 3.5mm to 4mm. This range can meet the binding requirements of most garment industries.

[0008] Preferably, the ratio of the warp density of the body portion to the warp density of the edging portion is 1.5 to 2. This ratio allows for the use of a reasonable amount of material during the fabric processing of the zipper, thus saving costs.

[0009] Preferably, if the warp density of the main body is greater than the warp density of the chain tooth sewing part, then the chain tooth sewing part can also have better flexibility.

[0010] Preferably, the binding part is woven with alternating patterns of three up and one down and one up and three down, which makes the binding part easy to process.

[0011] Preferably, the chain tooth sewing part and the binding part are made of twill weave; the body part is made of plain weave.

[0012] Preferably, the double-layer structure has a cavity; the cavity is filled with a flexible filler. The double-layer structure forms a bulging structure, which allows the sewing thread to be located inside the double-layer structure, so the sewing thread will not come into contact with the human body.

[0013] Furthermore, the flexible filler is a stitch. This structure facilitates the sewing of the flexible filler together with the double-layer structure.

[0014] Furthermore, the flexible filler is cotton, which is easy to fill in the cavity.

[0015] This utility model also relates to a zipper, comprising: a zipper pull and two single-sided toothed chains, each of the single-sided toothed chains comprising a chain tooth and a fabric strip of the zipper, the chain tooth being arranged along the length direction of the fabric strip of the zipper.

[0016] The zipper of this invention can effectively reduce the cost of the fabric tape used in zipper production and improve the user's experience when using the edging section. Attached Figure Description

[0030] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0031] Please refer to the accompanying drawings. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention.

[0032] In the following description, the length direction of the zipper tape refers to the direction relative to... Figure 1 The inward and outward directions of the paper surface, and the width direction of the zipper tape, refer to the direction relative to... Figure 1 The left and right directions on the paper.

[0033] Example 1

[0034] like Figure 1 and Figure 2 As shown, the zipper tape of this embodiment includes: a chain tooth sewing part 110, a body part 120, and an edge binding part 130 arranged sequentially along the width direction; the chain tooth sewing part 110 is used to connect the chain teeth 10; the edge binding part 130 is used to connect the sewn part 20; the edge binding part 130 has a double-layer structure; the warp thread arrangement density of the body part 120 is greater than the warp thread arrangement density of the edge binding part 130.

[0035] In the zipper tape of this utility model, the zipper tooth sewing part 110, the body part 120, and the binding part 130 are arranged sequentially, which allows the binding part 130 to be directly provided on the zipper tape, reducing sewing difficulty and the number of sewing operations. The binding part 130 has a double-layer structure, which facilitates sewing the part to be sewn 20 onto the binding part 130. Due to the high warp density of the body part 120, the body part 120 has good toughness. Due to the low warp density of the binding part 130, the binding part 130 achieves lightweight while maintaining thickness. Moreover, compared with existing ordinary zippers, the binding part 130 of this embodiment has better softness and a better skin feel. When sewing the part to be sewn 20 onto the zipper tape, no special parts are required, and it can be sewn like an existing ordinary zipper. In terms of manufacturing the zipper tape, since no special treatment is required on the loom, it can be produced like existing ordinary tape. The zipper tape can be expanded in size and product as needed. The zipper teeth sewing section 110, the body section 120, and the binding section 130 form an integrated woven structure. This integrated woven structure is formed by multiple warp and weft threads interlacing and weaving; the warp threads run in the same direction as the body section 120. This structure allows the zipper teeth sewing section 110, the body section 120, and the binding section 130 to be manufactured simultaneously.

[0036] If the width of the binding portion 130 is too large, it will be unsightly; if the width of the binding portion 130 is too small, it will be difficult to connect stably with the sewn portion 20. In this embodiment, the width W1 of the binding portion 130 is 3.5mm to 4mm. This range of width W1 of the binding portion 130 maintains aesthetics while also ensuring a stable connection between the binding portion 130 and the sewn portion 20, meeting the binding requirements of most garment industries.

[0037] The ratio of the warp density of the body portion 120 to the warp density of the binding portion 130 is 1.5 to 2. This ratio allows for the use of a reasonable amount of material during the fabric processing of the zipper, thus saving costs.

[0038] If the warp density of the main body 120 is greater than that of the chain tooth sewing part 110, then the chain tooth sewing part 110 can also have better flexibility.

[0039] The binding portion 130 is woven with alternating patterns of three up-one down and one up-three down, which makes the binding portion 130 easy to process. The zipper tape of this embodiment can be applied to nylon zippers.

[0040] The zipper tape is made of twill weave for the zipper teeth sewing part 110 and the binding part 130, and plain weave for the body part 120. Therefore, the zipper tape can be processed using a conventional loom.

[0041] Preferably, the width W1 of the binding portion 130 is 3.75 mm. The warp density of the body portion 120 is 300 dtex, the warp density of the binding portion 130 is 150 dtex, and the warp density of the chain tooth sewing portion 110 is 150 dtex.

[0042] The zipper of this embodiment includes: a zipper pull and two single-sided toothed chains, each single-sided toothed chain including a chain tooth 10 and a zipper tape, the chain tooth 10 being arranged along the length direction of the zipper tape.

[0043] The zipper of this embodiment can effectively reduce the cost of the fabric tape used to produce the zipper and improve the user's experience when using the binding part 130.

[0044] The zipper tape reduces sewing difficulty while providing a simple binding effect to the binding portion 130. The binding portion 130 uses a double-layer structure woven with finer yarns at a lower warp density, while the body portion 120 uses a coarser yarn woven with a higher warp density. Although the binding portion 130 and the body portion 120 have different thicknesses, the difference is minimal, resulting in minimal variation in the zipper tape thickness. Therefore, it is less likely to cause adverse effects during finished product processing. In this embodiment, the zipper tape can be manufactured using conventional looms and sewing machines simply by modifying the existing tape weave structure.

[0045] like Figure 1 , Figure 3 and Figure 4 As shown, the garment 40 has an opening 41, a sewn part 20 is disposed on the opening 41, and a zipper is sewn onto the sewn part 20. The garment 10 of this invention can effectively reduce production costs and improve the contact feel between the edge of the zipper tape on the garment 10 and the human skin.

[0046] Example 2

[0047] like Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the width W1 of the binding portion 130 is 3.5 mm. The warp density of the body portion 120 is 450 dtex, the warp density of the binding portion 130 is 300 dtex, and the warp density of the chain tooth sewing portion 110 is 300 dtex.

[0048] Example 3

[0049] like Figures 6 to 8 As shown, the difference between this embodiment and embodiment 1 is that the double-layer structure has a cavity 131; the cavity 131 is provided with a flexible filler 140.

[0050] Because the double-layer structure forms a bulging structure, if the sewn part 20 is sewn onto the main body 120 via the article sewing line 30, the binding part 130 will touch the human body, while the article sewing line 30 will not touch the human body; in addition, if the sewn part 20 is sewn onto the binding part 130 (not shown) via the article sewing line 30, the article sewing line 30 can be located inside the binding part 130, and the article sewing line 30 will not touch the human body.

[0051] Since the chain tooth sewing part 110, the body part 120 and the binding part 130 are all woven structures, the chain tooth sewing part 110, the body part 120 and the binding part 130 can be woven at the same time. Therefore, during the process of sewing the sewn part 20 to the zipper tape, only one item sewing thread 30 needs to be sewn at one place, which can reduce the sewing process.

[0052] Preferably, the flexible filler 140 is the suture. The double-layer structure forms a raised structure, allowing the suture to reside inside the double-layer structure, thus preventing it from touching the human body. This structure facilitates the sewing of the flexible filler 140 to the double-layer structure, simplifying manufacturing.

[0053] There are multiple sutures, all twisted together to form a single thread. This single thread ensures both the required softness of the flexible filling material 140 and a certain degree of strength.

[0054] To fix the position of the flexible filler 140 within the edging portion 130, two structures for fixing the flexible filler 140 can be employed. For example... Figure 7 As shown, the first structure for fixing the flexible filler 140 is as follows: the flexible filler 140 is inserted into the binding portion 130. The binding portion 130 is a woven structure. The flexible filler 140 is provided before the binding portion 130 is woven and tightened. Therefore, when the binding portion 130 is tightened, a structure is formed in which the flexible filler 140 is inserted into the binding portion 130, which is convenient for manufacturing. Figure 8 As shown, the second type of structure for fixing the flexible filler 140 is as follows: the flexible filler 140 is connected to the edging portion 130 by stitching, and the flexible filler and the edging portion 130 are sewn together to achieve positioning of the flexible filler 140. In this embodiment, the edging portion 130 is a cylindrical structure.

[0055] Figure 7 In this context, the inside of the zipper tape refers to the area relative to the inside of the zipper tape. Figure 7 The upward direction of the paper, the outer side of the zipper tape refers to the direction relative to... Figure 7The paper is facing downwards. In this embodiment, the sewn part 20 is sewn onto the outside of the binding part 130. The connection point A between the inner side of the main body 120 and the binding part 130 is a position that is easily touched by the skin, and the side B of the binding part 130 away from the main body 120 is a position that is easily touched by the hand or skin. Due to the structure of the binding part 130, the connection point A between the inner side of the main body 120 and the binding part 130 and the side B of the binding part 130 away from the main body 120 are both smoothly transitioned structures, which prevents the human body from feeling any contact with the edges.

[0056] Because a binding portion 130 is provided on the edge of the zipper tape away from the zipper teeth, and the binding portion 130 protrudes from the body portion 120 structure in the thickness direction, the edge of the binding portion 130 can form a conspicuous guiding line. When it is necessary to set the sewing line L on the body portion 120 (such as... Figure 3 As shown), the sewing path L can be set along the guide line of the binding part 130. When the zipper is sewn onto the sewn part 20, it can prevent the zipper from tilting during the sewing process and help the sewing worker to see more clearly while sewing.

[0057] Example 4

[0058] like Figure 9 As shown, the difference between this embodiment and Embodiment 3 is that the number of sutures is one.

[0059] Example 5

[0060] like Figure 10 and Figure 11 As shown, the difference between this embodiment and Embodiment 3 is that there are multiple stitches, all of which are arranged sequentially along the width direction of the binding portion 130. This structure allows the multiple stitches to be evenly distributed inside the binding portion 130, making it easier for the multiple stitches to fill the interior of the binding portion 130.

[0061] The manufacturing method of the zipper tape binding portion 130 in this embodiment is as follows: According to the structure of the zipper tooth sewing portion 110, the body portion 120, and the binding portion 130, multiple warp threads, multiple weft threads, and multiple stitches arranged sequentially along the width direction of the binding portion 130 are arranged. The warp and weft threads are interwoven and woven together. After the zipper tooth sewing portion 110, the body portion 120, and the binding portion 130 form an integrated woven structure, before the binding portion 130 is woven and tightened, all stitches are located inside the binding portion 130 to be tightened, and all stitches constituting the flexible filler 140 are inserted into the binding portion 130. After the zipper tooth sewing portion 110, the body portion 120, and the binding portion 130 form an integrated woven structure, both ends of the flexible filler 140 are connected to the binding portion 130.

[0062] Example 6

[0063] like Figure 12 As shown, the difference between this embodiment and embodiment 3 is that the flexible filler 140 is cotton, which is easy to fill in the cavity 131.

[0064] The manufacturing method of the zipper tape edge portion 130 in this embodiment is as follows: according to the structure of the chain tooth sewing portion 110, the body portion 120 and the edge portion 130, multiple warp threads and multiple weft threads are arranged, and the warp threads and weft threads are interlaced and woven together, forming an integral woven structure of the chain tooth sewing portion 110, the body portion 120 and the edge portion 130; before the warp and weft threads are woven and gathered, cotton is placed inside the edge portion 130 to be gathered, and then the warp and weft threads are gathered.

[0065] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0066] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
