[0055] Hereinafter, non-limiting embodiments and features of the present invention will be described with reference to the accompanying drawings. Those skilled in the art will be able to combine the various embodiments and / or features without excessive explanation, and will also understand the synergistic effects of such combinations. Repeated descriptions between embodiments are generally omitted. The accompanying drawings are primarily for the purpose of describing the utility model and are simplified for ease of drawing.

[0056] Reference Figure 1 In the zipper tooth strip 1, a coil-shaped component 2 is woven into the zipper strip 3 and fixed to the first side edge 31 of the zipper strip 3. The coil-shaped component 2 includes a plurality of zipper teeth 9, each constituting a turn of the coil-shaped component 2. In zippers not shown, the zipper tooth strips 1 are used in pairs in a manner that allows them to be opened and closed by a zipper pull (not shown). The zipper tooth strip 1 extends in a long strip with a specified width. The zipper tooth strip 1 is flexible in both the width and length directions, that is, even when the coil-shaped component 2 is woven into the zipper strip 3, a certain degree of flexibility can be ensured. In addition, the width and length directions mentioned here are equivalent to the weft and warp directions described later.

[0057] The zipper tape 3 includes multiple warp yarns 4, which alternately have raised portions 5 as they extend along their length. m 6 m and the sunken part 5 n 6n And through the buoyancy section 5 m 6 m The collection of yarns creates a pattern of at least two colors on the coiled component 2. Additionally, as will be specifically understood from the description below, the raised portion is the part exposed on the surface of the zipper tooth belt 1 compared to the zipper teeth or weft yarn. Furthermore, as will be specifically understood from the description below, the multiple warp yarns 4 include at least two warp yarns 5, 6 with complementary floating and sinking cycles, thereby enabling more diverse and / or denser patterns. In some cases, including the example shown in the figure, the fastening yarns used to secure the coiled component 2 to the warp yarns and / or base fabric introduced to stabilize the spacing of the zipper teeth 9 are used as the aforementioned multiple warp yarns 4.

[0058] The pattern can be presented based on the different colors among the multiple warp yarns 4. To make the pattern visually striking, the color of the multiple warp yarns 4 can be different from the color of the loop-shaped component 2, and more specifically, from the color of the monofilament forming the loop-shaped component 2, but is not limited to this. To make the pattern visually striking, the color of the multiple warp yarns 4 can be different from the color of the main body of the zipper tape 3 (described later), but is not limited to this. The diversity of the pattern is related to the number of warp yarns 4. In this regard, since the loop-shaped component 2 has a narrower width than the zipper tape 3 in the weft direction, it can be understood that the number of multiple warp yarns 4 also has an upper limit. The density of the pattern is related to the float-sink cycle of the warp yarns. In this regard, it is advantageous to select or introduce warp yarns with shorter float-sink cycles. This will be explained in more detail below.

[0059] Zipper tape 3 features multiple bottom warp yarns 3 m and at least 1 weft yarn 3 n The woven base structure. Furthermore, the zipper tape 3 includes a first side edge portion 31 and a tape body portion 32; in other words, it is divided into a first side edge portion 31 and a tape body portion 32 in the weft direction. The tape body portion 32 includes a base warp yarn 3. m Weft yarn 3 n The woven base structure is typically composed of only a base structure, but is not limited to this. There are no limitations on the type (plain weave, twill weave, etc.) and combination of fabric structures in the main body portion 32. Furthermore, the width of the main body portion 32 is generally greater than the width of the first side edge portion 31. The yarns constituting the zipper tape 3 are typically multifilament yarns or staple fiber yarns composed of multiple filaments, but are not limited to these. Preferably, yarns that can unfold naturally are used in the unrestrained portions.

[0060] The first side edge portion 31 includes a base structure supporting the coil-shaped component 2, and multiple fastening yarns 7 for securing the coil-shaped component 2 to the base structure. In some cases, the first side edge portion 31 includes: multiple lower yarns 81-88 carrying the lower portions 92 of the multiple zipper teeth 9; and multiple fastening yarns 71-76 securing the coil-shaped component 2 to the base structure. Multiple lower yarns 81-88 and weft yarns 3 are used. n The base structure of the first side edge portion 31 is woven. The loop-shaped component 2 is fastened to the base structure by fastening yarns 71 to 76. Even without inserting a core cord into the loop-shaped component 2, the upper leg portion 91 and lower leg portion 92 of the zipper tooth 9 (described later) deform to contact each other, but it is still possible to guide one or more core cords into the loop-shaped component 2.

[0061] The coil-shaped component 2 is obtained by winding resin monofilaments with a width greater than that of the constituent yarns of the zipper tape 3 into a spiral shape, and each zipper tooth 9 constitutes one turn of the coil-shaped component 2. In other words, the coil-shaped component 2 is obtained by continuously forming multiple zipper teeth 9 in the spiral of monofilaments. The coil-shaped component 2 has a certain weft width and extends in a long strip along the warp direction. Multiple zipper teeth 9 are continuously arranged in the warp direction. Each zipper tooth 9 includes an upper leg portion 91, a lower leg portion 92, an engaging head 93, and a reversing portion 94. Generally, the coil-shaped component 2 is woven into the first side edge portion 31 by feeding monofilaments with engaging heads 93 formed at predetermined intervals into a knitting machine, but this method is not limited to this method.

[0062] In each zipper tooth 9, the upper leg portion 91 and the lower leg portion 92 extend in the weft direction. The engaging head 93 extends in the vertical direction, connecting the outer ends of the upper leg portion 91 and the lower leg portion 92 outside the tape surface of the zipper tape 3. The reversing portion 94 extends curvedly in the vertical direction, connecting the inner ends of the upper leg portion 91 and the inner ends of the lower leg portion 92 of adjacent zipper teeth 9 on the tape surface of the zipper tape 3. The engaging head 93 has a wider portion in the warp direction than other parts of the monofilament (e.g., the upper leg portion 91 and the lower leg portion 92), thereby enabling the engagement and disengagement of the coil-shaped components used as engaging pairs. In addition, the aforementioned outer and inner ends are defined in the in-plane direction of the zipper tape 3.

[0063] In this embodiment, the multiple warp yarns 4 include at least two warp yarns 5 and 6 with complementary floating and sinking periods, thereby enabling more diverse and / or denser patterns. Because at least two yarns have complementary floating and sinking periods, in the warp direction, where one warp yarn is submerged and not visible from the outside, another warp yarn floats up and becomes visible from the outside. Therefore, the diversity and / or density of the pattern can be improved. Furthermore, each floating portion forms a pixel, and the pattern is formed by the collection of floating portions (hereinafter, there are cases where floating portions are equated with pixels). Preferably, at least two warp yarns 5 and 6 are adjacent in the weft direction, but this is not a limitation. The warp yarns have a natural expansion in their floating portions, so even if there is another warp yarn between at least two warp yarns, it can be concealed.

[0064] At least two warp yarns 5, 6 include: a first warp yarn 5, which extends meanderingly in the vertical direction and alternately has a first float 5 as it extends in the warp direction. m and the first sunken section 5 n ; and a second warp 6, which meanders in the vertical direction and alternately has a second levitation portion 6 as it extends in the warp direction. m Second sinking part 6 n The first floating part 5, which is the same or different in color m Second floating part 6 m Alternating zigzag patterns along the meridional direction (see reference) Figure 2 Preferably, the number of first warp yarns 5 is 2, 3, 4, or 5 or more, with an upper limit of 10 or less or 8 or less. The same applies to the number of second warp yarns 6. In addition, the number of first warp yarns 5 and second warp yarns 6 can be changed according to the size of the zipper or the thickness of the warp yarns.

[0065] Reference Figure 1 , Figure 2 The following will be explained together. On the upper surface of the upper foot 91, the first warp yarn 51, the second warp yarn 61, the first warp yarn 52, 53, the second warp yarn 62, the first warp yarn 54, the second warp yarn 63, the first warp yarn 55, and the second warp yarn 64 are arranged sequentially along the weft direction (see reference). Figure 1 ). The floating part 5 of the first warp 51 m The floating part 6 of the second warp 61 m The pixel column L1 is formed by alternating zigzag patterns in the upward direction (see reference). Figure 2 ). The floating part 5 of the first warp yarns 52 and 53 m The floating part 6 of the second warp 62 m The pixel column L2 is formed by alternating zigzag patterns in the upward direction (see reference). Figure 2Similarly, pixel columns L3 and L4 are formed. Furthermore, the width and variety of the pattern can be expanded by increasing the number of pixel columns, but as mentioned above, the number of columns is limited within the restricted width of the coil-shaped component 2. Preferably, the number of columns is in the range of 3 to 8. Additionally, the number of columns can be varied depending on the size of the zipper or the thickness of the warp yarns.

[0066] If it can be based on Figure 2 As understood, the exposure of the fastening yarns 71-76 (especially fastening yarns 71-74) is suppressed by the warp yarns 5 and 6 (of course, sometimes the fastening yarn 7 may also be slightly exposed). That is, even if the fastening yarn 7 is inserted between the warp yarns 5 and 6, the pattern can be constructed solely by the warp yarns 5 and 6. From this point of view, the number of fastening yarns 7 is less than the number of at least two warp yarns 5 and 6, and / or the color of the fastening yarn 7 is the same as or a similar color to the monofilament. Similar colors refer to colors adjacent on the color wheel. Furthermore, it is preferable to arrange the warp yarns 5 and 6 on both sides of the fastening yarn 7, with the fastening yarn 7 sandwiched between the warp yarns 5 and 6, so that the exposure of the fastening yarn 7 can be suppressed by the warp yarns 5 and 6.

[0067] If the first warp 5 and the second warp 6 are the same color, a single-color pixel column is formed, which can form a warp stripe pattern on the coil-shaped component 2. For example, in pixel columns L1 to L4, when pixel columns L1 and L4 are set to the first color and pixel columns L2 and L3 are set to the second color, pixel columns L2 and L3 form a central line extending along the warp direction, and pixel columns L1 and L4 form side lines on both sides of the central line, thereby forming a warp stripe pattern.

[0068] If the first warp 5 and the second warp 6 are different colors, then a pixel column with alternating arrangement of pixels of the two colors in the warp direction can form a grid pattern, dot pattern, and / or (e.g., weft) stripe pattern on the coil-shaped component 2. For example, each pixel column in pixel columns L1 to L4 is set such that pixels of the first color and pixels of the second color are arranged alternately in the warp direction. When the first color pixels throughout pixel columns L1 to L4 are arranged side by side with each other in the weft direction, and the second color pixels are also arranged side by side in the weft direction, the first color lines formed by the first color pixels arranged side by side in the weft direction and the second color lines formed by the second color pixels arranged side by side in the weft direction are alternately formed in the warp direction, thereby forming a weft stripe pattern.

[0069] In another scenario, pixels in pixel columns L1 through L4 are arranged alternately in the longitudinal direction, with pixels of the first and second colors. In pixel columns L1 and L2, pixels of the first color are arranged side-by-side in the latitudinal direction, and pixels of the second color are also arranged side-by-side in the latitudinal direction. Similarly, in pixel columns L3 and L4, pixels of the first color are arranged side-by-side in the latitudinal direction, and pixels of the second color are also arranged side-by-side in the latitudinal direction. When the pixels of the first color in pixel columns L1 and L2 and the pixels of the second color in pixel columns L3 and L4 are arranged side-by-side in the latitudinal direction, a grid pattern or dot pattern is formed. In this example, two pixels arranged side-by-side in the latitudinal direction correspond to a single square or a single dot.

[0070] Typically, the floating and sinking cycle of the first warp 5 and the second warp 6 is equal to the spacing (cycle or configuration interval) of the plurality of zipper teeth 9 in the coil-shaped component 2 (e.g., refer to...). Figure 2 This allows for the formation of a denser pattern. Furthermore, it reduces the exposed area of ​​the upper part 91 of the zipper teeth 9, enhancing the overall unity or uniformity of the pattern.

[0071] In either case, it is advantageous to ensure or import a sufficient number of first warp yarns 5 and second warp yarns 6. Figure 1 In the case shown, five first warp yarns 51-55 and four second warp yarns 61-64 are used. It should be clarified that the number of first warp yarns 5 and second warp yarns 6 does not have to be different or the same.

[0072] In some cases, the first buoy 5 m Supported by the upper foot 91 of the zipper tooth 9, the second floating part 6 m The weft portion 3 between the upper legs 91 of adjacent zipper teeth 9 inserted into the coil-shaped component 2 j Support (reference) Figure 3 Therefore, the first warp 5 and the second warp 6 can have the same floating / sinking cycle as the spacing of the zipper teeth 9 (of course, other structures can also be used). Preferably, the floating / sinking depth of the first warp 5 is different from that of the second warp 6. This facilitates the use of different types of warp yarns as the first and second warp yarns.

[0073] like Figure 3 As shown in the example diagram, the first warp 5 preferably extends in a meandering manner: repeatedly crossing the upper foot 91 of the zipper tooth 9 above, and crossing the weft portion 3 below between the upper foot 91 of adjacent zipper teeth 9 inserted into the loop-shaped member 2. j .like Figure 4As shown, the second warp yarn 6 meanders and extends in the following manner: repeatedly crossing the weft section 3 above. j The first warp 5 and the second warp 6 are introduced to improve the spacing accuracy of the zipper teeth 9, and are effectively used as warp yarns for presenting patterns on the coiled part 2. This avoids the need to introduce additional warp yarns to present patterns and also helps to reduce the cost and / or lighten the weight of the zipper tooth belt 1. In addition, the first warp 5 and the second warp 6 can be fed in a manner with a lower tension than the fastening yarn, so that the pattern can be effectively exposed on the upper surface of the upper part 91 by the unfolding of the multifilament yarn or staple fiber yarn, or the exposure of other yarns (e.g., fastening yarn 7) can be effectively suppressed. In the embodiment, the weaving is performed with only the second warp 6 being woven in a manner with a lower tension than the fastening yarn.

[0074] Weft yarn part 3 j It is crossed on the upper side by the second warp yarn 6 and on the lower side by the first warp yarn 5, and is held between the first warp yarn 5 and the second warp yarn 6 in the vertical direction. As a result, the weft portion 3... j It can be located at the center position between adjacent upper foot sections 91 in the warp direction. Additionally, the weft section 3... j It can be used with the weft yarn 3 in the main body 32 n It can be continuous or discontinuous. In the example diagram, the weft portion 3... j It includes, but is not limited to, two weft yarn sections that are aligned in the weft direction and adjacent in the warp direction; it may also include one or three equal weft yarn sections.

[0075] In some cases, the thickness of the first warp 5 differs from that of the second warp 6, thereby improving the aesthetics of the pattern. In some situations, the first warp 5 is thicker than the second warp 6. In other situations, the second warp 6 is thicker than the first warp 5. The first warp 5 can comprise multiple warp yarns of varying thicknesses. The same applies to the second warp 6. For a portion of the first warp 5, a warp yarn thicker than the second warp 6 can be used, and for another portion of the first warp 5, a warp yarn thinner than the second warp 6 can be used. The yarn thickness can be measured not only by physical measurement on the zipper teeth 1 but also by comparison according to denier standards.

[0076] Although it is repeated, the zipper tape 3 includes multiple fastening yarns 7 for securing the loop-shaped component 2 to the base fabric as an addition to the aforementioned multiple warp yarns 4. The base fabric supporting the loop-shaped component 2, as described herein, includes, in the illustrated example, the aforementioned bottom yarns 81-88 and weft yarns 3. nBy using warp yarns other than the fastening yarn 7 as the first and second warp yarns, more than one problem that might arise without doing so can be avoided or suppressed. For example, the following problems can be avoided or suppressed: If the fastening yarn 7 is used to form the pattern, the density of the pattern will decrease. There is also the situation where it is difficult to obtain sufficient volume and / or width due to the tension applied to the fastening yarn 7. Without the bottom yarn 8, the fastening yarn 7 will cause the weft yarn 3 to be pulled upwards. n .

[0077] The multiple warp yarns 4 can be of different thicknesses than the multiple fastening yarns 7. When the multiple warp yarns 4 are thicker than the fastening yarns 7, the exposure of the fastening yarns 7 can be suppressed. When the multiple warp yarns 4 are thinner than the fastening yarns 7, a design with higher straightness can be obtained. In this case, to suppress the exposure of the fastening yarns 7, it is preferable to use multiple sets of multiple warp yarns 4. Furthermore, it is preferable that the number of fastening yarns 7 is less than the number of multiple warp yarns 4 (the total number of the first warp yarns 5 and the second warp yarns 6). Thus, the proportion of warp yarns 4 (first warp yarns 5 and second warp yarns 6) is higher than that of the fastening yarns 7, which can more effectively suppress the exposure of the fastening yarns 7. It should be clarified that in Figures 3 to 5 In the organization shown, even if the fastening yarn 7 is completely omitted, the coiled component 2 can be woven into the zipper tape 3 without any problems.

[0078] In another embodiment, multiple warp yarns 4 are used as fastening yarns 7 to secure the loop-shaped component 2 to the base fabric. That is, fastening yarns 7a and 7b (see reference) are used. Figure 6 (as the first and second warp yarns) replaces the first warp yarn 5 and the second warp yarn 6 mentioned above. In this case, as from Figure 6 As is known, the fastening yarns 7a and 7b swing complementarily and are exposed complementaryly above each other, resulting in the ability to achieve the same effect as described above without contradiction. Typically, the fastening yarns 7 alternately repeat the upper leg 91 crossing one of the adjacent zipper teeth 9 in the warp direction on the upper side and the lower leg 92 crossing the other tooth on the lower side. Preferably, the bottom weave comprises lower yarns 8 extending (usually multiple) along the warp direction in such a way that each lower leg 92 of the plurality of zipper teeth 9 inserted into the loop-shaped member 2 is accompanied by a weft yarn portion 3 disposed below (e.g., directly below) each lower leg 92. j Between. The lower yarn 8 prevents the fastening yarn 7 from pulling the weft yarn 3 upwards. n In addition, although Figure 6 Not shown, but the weft yarn located between the zipper teeth 9 can also be located in a position sandwiched between the fastening yarn and the lower yarn 8.

[0079] The pattern of at least two colors formed by the fastening yarns 7a and 7b on the loop-shaped member 2, as described above, can be formed into a checkered pattern, a dotted pattern, and / or a striped pattern. Additionally, as in... Figure 1 As shown in the case of 7, the number of fastening yarns 7 is in the range of 3 to 10. The number of fastening yarns 7 can also be changed according to the size of the zipper or the thickness of the fastening yarns 7.
