Description

Technical Field

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

[0002] As the apparel market gradually adopts a lightweight trend, such as lightweight down jackets, skin-friendly clothing, and sun-protective clothing, the requirements for the zipper tape manufacturing process have also increased. Existing technology discloses a zipper tape that uses a plain weave in the sewing area. This not only prevents misalignment of the warp and weft threads but also increases the rigidity of the zipper tape, effectively preventing wrinkles in the fabric after the zipper is sewn onto it.

[0003] However, the predominantly plain weave in the sewn area of ​​the zipper tape results in some of the wavy texture remaining exposed after the zipper tape is sewn onto the fabric, leading to unevenness and affecting the aesthetics. Furthermore, the overall zipper tape is relatively thick and stiff, making it more suitable for heavy fabrics and incompatible with the current trend towards lightweight fabrics. Therefore, this paper proposes a zipper tape and zipper designed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a zipper tape and zipper that solves the technical problems of existing zipper tapes having a large proportion of plain weave in the sewn area, and the wavy part of the sewn area still being exposed after the zipper tape is sewn onto the fabric, resulting in uneven zipper tapes that affect aesthetics.

[0005] To achieve the above objectives, this utility model provides a zipper tape, formed by weaving warp and weft threads, comprising:

[0006] Installation area for installing chain teeth;

[0007] An exposed area, wherein the exposed area is integrally formed with the adjacent side of the mounting area;

[0008] The sewing area is integrally formed with the adjacent side of the exposed area, and the sewing area adopts a 3-up 3-down weft plain weave.

[0009] The selvage area is integrally formed with the adjacent edge of the sewing area;

[0010] The exposed area includes at least three sequentially arranged combined areas in the width direction of the zipper tape;

[0011] One of the combined regions employs a 2-upper-2-lower weft-overlapping weave;

[0012] Any two adjacent combined regions among the three combined regions have different weave structures;

[0013] The combined area adjacent to the sewn area in the exposed area has a different weave structure than the sewn area;

[0014] The combined area adjacent to the installation area in the exposed area has a different weave structure than the installation area.

[0015] Preferably, the exposed area includes a first combined area, a second combined area, a third combined area, and a fourth combined area arranged sequentially along the width direction of the zipper tape. The first combined area is adjacent to the installation area, and two adjacent combined areas in the first combined area, the second combined area, the third combined area, and the fourth combined area have different weave structures.

[0016] Preferably, the first combined area adopts a 1-up-1-down plain weave; the second combined area and the fourth combined area respectively adopt a 2-up-2-down warp plain weave; and the third combined area adopts a 2-up-2-down weft plain weave.

[0017] Preferably, the exposed area accounts for 18%-25% of the zipper tape width, and the sewn area accounts for 27%-38% of the zipper tape width.

[0018] Preferably, the diameter of the warp is less than or equal to the diameter of the weft.

[0019] Preferably, the selvage area adopts a 2-up-2-down warp-cut twill weave and / or a 2-up-2-down warp-cut twill weave, and the ratio of the sewn area to the selvage area is between 3:1.5 and 3:2.5.

[0020] Preferably, the installation area adopts a 2-up, 2-down warp-cut twill weave.

[0021] Preferably, the installation area adopts a 2-up, 2-down overlapping flat structure, and the width of the installation area is between 2-4mm.

[0022] Preferably, an adhesive layer is provided at the bottom of the zipper tape.

[0023] A zipper comprising the zipper tape described in any of the preceding claims.

[0024] Compared with the above-mentioned background technology, the zipper tape provided by this utility model has the following beneficial effects:

[0025] I. In this utility model, the sewing area adopts a 3-up, 3-down weft-overlay plain weave. Because the weft float is increased to three strands, the zipper tape's extensibility in the weft direction is improved, making the weft arrangement in the sewing area more sparse and facilitating needle insertion and withdrawal. Furthermore, the weft-overlay plain weave extends the weft direction on top of the plain weave, with every other warp thread interlacing, achieving maximum bending rate (i.e., high warp stiffness). Simultaneously, it controls the warp tension in the sewing area to be lower than in other areas, allowing the warp threads in the sewing area to be woven in a longer length, forming a slight wave. This ensures that the seam shrinkage is precisely offset by the wave excess, reducing the wave pattern of the zipper tape after sewing. The zipper tape and fabric fit perfectly together, resulting in a smoother exposed area and fabric, solving the problem of seam arching and effectively improving the flatness of the zipper tape, thus enhancing its aesthetics.

[0026] Second, in this utility model, one of the combined areas of the exposed area adopts a 2-up 2-down weft-double plain weave. Weft-double plain weave is based on plain weave with weft extension. The weft yarn float makes the fabric surface present fine horizontal stripes, which can effectively improve the lateral elasticity and softness of the zipper tape. The overall exposed area can maintain flatness while minimizing the impact during sewing, making the zipper tape more compatible with lightweight fabrics. Attached Figure Description

[0040] Reference Appendix Figure 1 and attached Figure 2To achieve the above objectives, this utility model provides a zipper tape, comprising: an installation area 1, an exposed area 2, a sewing area 3, and a fabric edge area 4 arranged sequentially along the width direction of the zipper tape. The installation area 1, wherein the width direction of the zipper tape is... Figure 1 In the X direction, installation area 1 is used to install chain teeth 7, exposed area 2 is integrated with the adjacent side of installation area 1, sewing area 3 is integrated with the adjacent side of exposed area 2, and sewing area 3 is used to sew the fabric; sewing area 4 is integrated with the adjacent side of sewing area 3.

[0041] See attached document Figure 3 Appendix Figure 4 and attached Figure 5 The outer surface of sewing area 3 has longitudinal raised stripes, which can effectively identify this area as a sewing area in terms of appearance. In this design, sewing area 3 employs a 3-up, 3-down weft-overlay plain weave. By using this weft-overlay, the weft float length is increased to three, enhancing the zipper tape's weft-direction extensibility. This results in a looser weft yarn arrangement in sewing area 3, facilitating needle insertion and withdrawal. Furthermore, the weft-overlay plain weave extends the weft direction on top of the plain weave, with every other warp yarn crossing over, achieving maximum bending stiffness (high warp yarn rigidity). Simultaneously, it controls the warp yarn tension in sewing area 3 to be lower than in other areas, allowing for a longer warp yarn length and creating a slight wave. This ensures that the seam shrinkage is offset by the wave excess, reducing the wave pattern on the zipper tape after sewing. The zipper tape and fabric fit together perfectly, resulting in a smoother exposed area 2 and a more even fabric surface. This solves the problem of seam arching and effectively improves the flatness of the zipper tape, thus enhancing its aesthetics. See the appendix for details. Figure 6 L represents the state of the zipper tape before sewing, at which time the sewing area 3 forms a slight wave shape; M represents the state of the zipper tape during sewing, with the needle insertion point 9 at the raised position; N represents the state of the zipper tape after sewing, after the sewing area 3 is sewn, the zipper tape reaches a flat state.

[0042] It should be noted that the exposed area 2 includes at least three sequentially arranged combination areas in the width direction of the zipper tape, and one of the combination areas adopts a 2-up 2-down weft-weighted plain weave. Weft-weighted plain weave is an extension of the weft direction on the basis of plain weave. The weft yarn float makes the fabric surface present fine horizontal stripes, which can effectively improve the lateral elasticity and softness of the zipper tape. The entire exposed area 2 can maintain flatness while minimizing the impact during sewing, thus making the zipper tape more compatible with lightweight fabrics.

[0043] It should be further noted that any two adjacent combination areas in the three combination areas have different weaving structures; the combination area adjacent to the sewing area 3 in exposed area 2 has a different weaving structure than the sewing area 3; the combination area adjacent to the installation area 1 in exposed area 2 has a different weaving structure than the installation area 1. This allows the zipper tape to have different weaving structure designs at different positions in the width direction, improving the flatness and softness of the exposed part of the zipper tape after sewing.

[0044] In one embodiment of this utility model, the exposed area 2 is constructed by sequentially combining a first combined area 201, a second combined area 202, a third combined area 203, and a fourth combined area 204. The first combined area 201 is adjacent to the installation area 1, and adjacent combined areas among the first, second, third, and fourth combined areas 201 and 202 have different weaving structures. Specifically, the first combined area 201 employs a 1-up, 1-down plain weave. Because the first combined area 201 is adjacent to the installation area 1, the warp and weft yarns of the 1-up, 1-down plain weave interweave every other yarn, resulting in more frequent interweaving and maximum bending, ensuring a stronger first combined area 201. This effectively reduces the lateral displacement of the warp yarns 5 in the installation area 1, thereby minimizing the impact on the zipper tape during sewing. The second combination area 202 and the fourth combination area 204 each employ a 2-up, 2-down warp-faced plain weave. Compared to a 1-up, 1-down weave, this reduces the number of warp and weft yarn bends, lowers stress concentration, and thus improves the wrinkle resistance and smoothness of the zipper tape. Simultaneously, the warp-faced plain weave surface exhibits fine longitudinal stripes, providing a richer visual effect than plain weave. The third combination area 203 employs a 2-up, 2-down weft-faced plain weave. Weft-faced plain weave is an extension of the plain weave in the weft direction. The weft yarn floats create fine transverse stripes on the fabric surface, effectively improving the lateral elasticity and softness of the zipper tape. The overall exposed area 2 maintains smoothness while minimizing the impact during sewing.

[0045] It should be noted that the width of the exposed area 2 is between 3-5mm. Optionally, the width of the exposed area 2 can be designed to be 3mm, 4mm, or 5mm according to actual needs. The main purpose is to keep it flat while minimizing the impact of sewing.

[0046] It should be further noted that the exposed area 2 accounts for 18%-25% of the width of the zipper tape, and the sewn area 3 accounts for 27%-38% of the width of the zipper tape. Of course, the specific dimensions of the exposed area 2 and the sewn area 3 need to be adjusted according to the overall width of the zipper tape. By adjusting the proportion of the sewn area 3 of the zipper tape, the sewn area 3 can be covered inside the fabric, thereby making the exposed area 2 flatter.

[0047] In some embodiments of this utility model, the selvage area 4 adopts a 2-up-2-down warp-broken twill weave and / or a 2-up-2-down twill weave. That is, the selvage area 4 can adopt a 2-up-2-down warp-broken twill weave alone, or a 2-up-2-down twill weave alone, or a 2-up-2-down warp-broken twill weave and a 2-up-2-down twill weave simultaneously. The purpose is to reduce the warp density 5, making the selvage area 4 thinner and thus improving the softness of the selvage area 4. At the same time, the ratio of the zipper tape sewing area 3 to the selvage area 4 is precisely controlled between 3:1.5 and 3:2.5. Optionally, the ratio of the zipper tape sewing area 3 to the selvage area 4 is set to 3:2, which maximizes the softness of the zipper tape while meeting the width required for sewing, thus making the zipper tape more compatible with the thin fabric.

[0048] In some embodiments of this utility model, both the weft yarn 6 and the warp yarn 5 are made of polyester yarn. Furthermore, the specification of the warp yarn 5 is less than or equal to the specification of the weft yarn 6. Optionally, the specification of the weft yarn 6 is 300D, and the specification of the warp yarn 5 is less than or equal to 300D. By adjusting the diameter ratio and specification of the warp and weft yarns 6, the softness of the zipper tape is improved while ensuring the rigidity of the zipper tape, making the thickness of the zipper tape more suitable for thin fabrics.

[0049] In some embodiments of this utility model, for nylon zippers, the mounting area 1 adopts a 2-up, 2-down warp-broken twill weave. (See attached diagram.) Figure 7 A 2-up, 2-down twill weave. Capable of attaching... Figure 7 Four warp points or four weft points are formed simultaneously in the area shown, maximizing the continuity of warp and weft points while ensuring tightness, which is more conducive to the needle piercing the suture chain teeth 7.

[0050] In some embodiments of this utility model, for both plastic steel zippers and metal zippers, the mounting area 1 adopts a 2-up, 2-down overlapping flat structure, as shown in the attached drawing. Figure 8 The 2-up, 2-down warp-flat weave increases the density of the warp threads 5, making them more tightly packed. This effectively improves the rigidity of the tape installation area 1 and enhances the physical strength of the tape. It should be noted that the width of the installation area 1 should be between 2-4mm to ensure stable installation of the zipper teeth 7.

[0051] Optionally, an adhesive layer 8 is provided at the bottom of the zipper tape. This adhesive layer significantly enhances the durability of the zipper tape, preventing damage during use and extending its lifespan. The adhesive layer 8 is made of either frosted adhesive or fabric adhesive, depending on the requirements. When frosted adhesive is used, its surface treatment creates a frosted effect, ensuring the zipper tape's aesthetics and texture. When fabric adhesive is used, the fabric base material ensures the zipper tape's breathability and resilience.

[0052] In addition to the zipper tape mentioned above, this utility model also provides a zipper that includes the zipper tape disclosed in the above embodiments. For the structure of other parts of the zipper, please refer to the prior art, which will not be described in detail here.

[0053] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0054] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
