[0021] Hereinafter, non-limiting embodiments and features of the present invention will be described with reference to the drawings. Those skilled in the art can combine each embodiment and / or each feature without the need for excessive explanation, and can also understand the synergistic effect of this combination. In principle, overlapping explanations between embodiments will be omitted. The reference drawings are primarily intended to describe the invention, and are simplified for the convenience of drawing.

[0022] Referring to FIG. 1, the fastener stringer 1 is formed by weaving a coiled member 2 including a plurality of fastener elements 9, each of which forms one turn of the coiled member 2, into a fastener tape 3 and fixing it to a first side edge portion 31 thereof. In a slide fastener (not shown), the fastener stringers 1 are used as a pair so as to be openable and closable by a slider (not shown). The fastener stringer 1 extends long with a predetermined width. The fastener stringer 1 has flexibility in the width direction and the longitudinal direction, that is, the weaving of the coiled member 2 into the fastener tape 3 also ensures a certain degree of flexibility of the fastener stringer 1. The width direction and the longitudinal direction described here are equivalent to the weft direction and the warp direction described later.

[0023] The fastener tape 3 has a raised portion 5 as it extends in the longitudinal direction. m ,6 m and Sedimentation Part 5 n ,6 n and the floating portion 5 m ,6 m The coil-shaped member 2 includes a plurality of warp threads 4 which present a pattern of at least two colors on the coil-shaped member 2 by a collection of the warp threads 4. As will be specifically understood from the description below, the floating portion is a portion which appears on the front side of the fastener stringer 1 relative to the fastener elements or the weft threads. As will be specifically understood from the description below, the plurality of warp threads 4 include at least two warp threads 5, 6 whose floating and sinking periods are complementary to each other, thereby making it possible to realize a more diverse and / or more detailed pattern. In some cases including the illustrated example, the warp threads introduced for stabilizing the pitch of the fastener elements 9 and / or the tightening threads for fixing the coil-shaped member 2 to the ground weave are used as the plurality of warp threads 4 described above.

[0024] The pattern can be presented based on the difference in color between the warp threads 4. In order to make the pattern more visually prominent, the color of the warp threads 4 may be different from the color of the coiled member 2, in short, the color of the monofilament forming it, but this is not necessarily limited. In order to make the pattern more visually prominent, the color of the warp threads 4 may be different from the color of the tape main body of the fastener tape 3, which will be described later, but this is not necessarily limited. The variety of the pattern correlates with the number of warp threads 4. In this regard, it is understood that the coiled member 2 has a narrower width in the weft direction than the fastener tape 3, and therefore there is an upper limit to the number of the warp threads 4. The denseness of the pattern correlates with the ups and downs cycle of the warp threads. In this regard, it may be advantageous to select or introduce a warp thread with a short ups and downs cycle. This will be explained in more detail below.

[0025] The fastener tape 3 is made of a large number of ground warp threads 3 m and at least one weft thread 3 n The fastener tape 3 further includes a first side edge portion 31 and a tape main body portion 32, in other words, it is divided into the first side edge portion 31 and the tape main body portion 32 in the weft direction. m and Weft 3 n The tape main body 32 includes a ground weave woven from a woven material, and typically consists of only a ground weave, but should not be limited thereto. There is no limitation on the type of weave (plain weave, twill weave, etc.) and combination of weaves in the tape main body 32. The tape main body 32 is typically wider than the first side edge portion 31. The constituent yarn of the fastener tape 3 is typically, but not limited to, a multifilament yarn composed of multiple filaments or a spun yarn. Preferably, a yarn having a natural spread in the unconstrained portion is used.

[0026] The first side edge 31 includes a ground structure supporting the coiled member 2 and a plurality of fastening threads 7 for fixing the coiled member 2 to the ground structure. In some cases, the first side edge 31 includes a plurality of lower threads 81-88 on which the lower legs 92 of the fastener elements 9 are placed, and a plurality of fastening threads 71-76 for fastening the coiled member 2 to the ground structure. n The ground structure of the first side edge portion 31 is woven from the core cord 71. The coil-shaped member 2 is fastened to the ground structure by the fastening yarns 71 to 76. No core cord is inserted in the coil-shaped member 2, and the fastener element 9 is deformed to the point where an upper leg portion 91 and a lower leg portion 92 (described later) come into contact with each other. However, it is possible to introduce one or more core cords into the coil-shaped member 2.

[0027] The coil-shaped member 2 is formed by winding a resin monofilament having a larger line width than the constituent threads of the fastener tape 3 into a coil shape, and each fastener element 9 forms one turn of the coil-shaped member 2. In other words, the coil-shaped member 2 is a monofilament spiral in which a plurality of fastener elements 9 are continuously formed. The coil-shaped member 2 extends long in the warp direction while having a constant latitudinal width. The plurality of fastener elements 9 are continuously arranged in the warp direction. Each fastener element 9 includes an upper leg portion 91, a lower leg portion 92, an engaging head portion 93, and an inverted portion 94. Typically, the coil-shaped member 2 is woven into the first side edge portion 31 by feeding a monofilament on which the engaging head portion 93 is formed at a predetermined pitch into a needle loom, but the method should not be limited to this method.

[0028] In each fastener element 9, the upper leg portion 91 and the lower leg portion 92 extend along the weft direction. The engaging head portion 93 extends in the vertical direction to connect the outer end of the upper leg portion 91 and the outer end of the lower leg portion 92 outside the tape surface of the fastener tape 3. The inverted portion 94 extends in a curved manner along the vertical direction to connect the inner end of the upper leg portion 91 and the inner end of the lower leg portion 92 of the adjacent fastener element 9 on the tape surface of the fastener tape 3. The engaging head portion 93 has a portion that is wider in the warp direction compared to other portions of the monofilament (for example, the upper leg portion 91 and the lower leg portion 92), which enables the coil-shaped members used as an engaging pair to be engaged and disengaged from each other. The outer end and the inner end described above are defined with respect to the in-plane direction of the fastener tape 3.

[0029] In this embodiment, the multiple warp threads 4 include at least two warp threads 5, 6 whose rising and sinking cycles are complementary, thereby enabling more diverse and / or more detailed patterns to be realized. At least two threads whose rising and sinking cycles are complementary are included, and therefore, in the warp direction, one warp thread is submerged and cannot be seen from the outside, and in the immediate vicinity of the position where another warp thread is raised and can be seen from the outside. Therefore, the variety and / or fineness of the pattern can be increased. Each raised portion forms one pixel, and a pattern is formed by a collection of the raised portions (hereinafter, the raised portion and the pixel may be described as being equivalent). The at least two warp threads 5, 6 are preferably directly adjacent in the weft direction, but this is not necessarily the case. The warp threads have a natural expansion at the raised portion, and therefore, even if there is another warp thread between the at least two warp threads, it can be hidden.

[0030] At least two warp threads 5, 6 form a first floating portion 5 as they extend in the warp direction. m and the first sinking part 5 n The first warp yarn 5 meanders up and down so as to have alternately the first and second floating portions 6 as it extends in the warp direction. m and the second sinking section 6 n The second warp yarn 6 has a meandering shape, and the first and second floating portions 5 of the same or different colors are arranged along the warp direction. m ,6 mare alternately arranged in a zigzag pattern (see FIG. 2). The number of first warp threads 5 is preferably 2, 3, 4, or 5 or more, with the upper limit being 10 or less, or 8 or less. The same applies to the number of second warp threads 6. The numbers of first warp threads 5 and second warp threads 6 can be changed depending on the size of the slide fastener and the thickness of the warp threads.

[0031] 1 and 2 are also referred to. On the upper surface of the upper leg portion 91, the first warp thread 51, the second warp thread 61, the first warp threads 52 and 53, the second warp thread 62, the first warp thread 54, the second warp thread 63, the first warp thread 55, and the second warp thread 64 are arranged in this order in the weft direction (see FIG. 1). m and the floating portion 6 of the second warp thread 61 m The first warp yarns 52 and 53 are alternately arranged in a zigzag pattern in the warp direction to form a pixel row L1 (see FIG. 2). m and the floating portion 6 of the second warp thread 62 m are alternately arranged in a zigzag pattern in the warp direction to form pixel row L2 (see FIG. 2). Pixel rows L3 and L4 are formed in a similar manner. Note that, although the width and variety of the pattern increases as the number of pixel rows increases, as described above, the number of rows is finite within the limited width of the coil-shaped member 2. Preferably, the number of rows is within a range of 3 to 8. Note that the number of rows can be changed depending on the size of the slide fastener and the thickness of the warp threads.

[0032] As can be seen from FIG. 2, the tightening yarns 71-76 (especially the tightening yarns 71-74) are prevented from appearing by the warp yarns 5, 6 (of course, the tightening yarn 7 may be slightly exposed). That is, even if the tightening yarn 7 is inserted between the warp yarns 5, 6, the pattern can be constructed mainly by the warp yarns 5, 6. From this viewpoint, the number of the tightening yarns 7 is at least less than the number of the two warp yarns 5, 6, and / or the color of the tightening yarn 7 is the same color as the monofilament or a similar color. A similar color means a color adjacent to the monofilament on the color wheel. In addition, it is preferable that the tightening yarn 7 is sandwiched between the warp yarns 5, 6 by being arranged on both sides of the tightening yarn 7, and the warp yarns 5, 6 suppress the appearance of the tightening yarn 7.

[0033] If the first warp thread 5 and the second warp thread 6 are the same color, a pixel row of a single color is formed, and a warp stripe pattern can be formed on the coil-shaped member 2. For example, among the pixel rows L1 to L4, if pixel rows L1 and L4 are set to a first color and pixel rows L2 and L3 are set to a second color, pixel rows L2 and L3 form a center line extending in the warp direction, and pixel rows L1 and L4 form side lines on both sides of the center line, forming a striped pattern in the warp direction.

[0034] If the first warp thread 5 and the second warp thread 6 are of different colors, a pixel row is formed in which pixels of two colors are alternately arranged in the warp direction, and a lattice pattern, a dot pattern, and / or a striped pattern (for example, in the weft direction) can be formed on the coil-shaped member 2. For example, if each of the pixel rows L1 to L4 is set so that pixels of a first color and pixels of a second color are alternately arranged in the warp direction, and the pixels of the first color are arranged in the weft direction across the pixel rows L1 to L4, and the pixels of the second color are also arranged in the weft direction, then first color lines formed by pixels of the first color arranged in the weft direction and second color lines formed by pixels of the second color arranged in the weft direction are alternately formed in the warp direction, forming a striped pattern in the weft direction.

[0035] In another case, each of the pixel rows L1 to L4 is set so that the first color pixels and the second color pixels are alternately arranged in the longitudinal direction, and the pixel row L 1, L2, the pixels of the first color are arranged in the horizontal direction, and the pixels of the second color are arranged in the horizontal direction, and the pixel row L 3, L4, the first color pixels are arranged in the horizontal direction, and the second color pixels are arranged in the horizontal direction, and the pixel column L 1, The first color pixel of L2 and pixel column L 3, The second color pixels of L4 are arranged in the horizontal direction, and the pixel column L 1, The second color pixel of L2 and pixel column L 3, If the pixels of the first color of L4 are arranged in the horizontal direction, a checkerboard pattern or a dot pattern is formed. In this example, two pixels arranged in the horizontal direction correspond to a single checkerboard or a single dot.

[0036] Typically, the period of rise and fall of the first warp thread 5 and the second warp thread 6 is equal to the pitch (period or arrangement interval) of the multiple fastener elements 9 in the coil-shaped member 2 (see, for example, FIG. 2). This promotes the formation of a more intricate pattern. In addition, the exposed area of ​​the upper leg portion 91 of the fastener element 9 is reduced, enhancing the unity or uniformity of the pattern.

[0037] In either configuration, it is advantageous to ensure or introduce a sufficient number of first and second warp threads 5, 6. In the case shown in Figure 1, five first warp threads 51-55 and four second warp threads 61-64 are used. Just to be clear, the numbers of first and second warp threads 5, 6 need not be different or equal.

[0038] In some cases, the first floating portion 5 m is supported by the upper leg portion 91 of the fastener element 9, and the second floating portion 6 m is supported by the weft portion 3j inserted between the upper leg portions 91 of the adjacent fastener elements 9 in the coil-shaped member 2 (see FIG. 3). This allows the first and second warp threads 5, 6 to have the same pitch of up-and-down period as the fastener elements 9 (of course, other configurations are also possible). Preferably, the up-and-down depth of the first warp thread 5 is different from the up-and-down depth of the second warp thread 6. This promotes the use of different types of warp threads as the first and second warp threads.

[0039] Preferably, as shown in the example of FIG. 3, the first warp thread 5 crosses the upper leg 91 of the fastener element 9 above, and crosses the weft thread portion 3j inserted between the upper leg portions 91 of the adjacent fastener elements 9 in the coil-shaped member 2 below, and then meanders. As shown in FIG. 4, the second warp thread 6 crosses the weft thread portion 3j above, and crosses the lower leg portion 92 of the fastener element 9 below, and then meanders. The first warp thread 5 and the second warp thread 6 are introduced to improve the pitch accuracy of the fastener element 9, and are effectively used as warp threads for presenting a pattern on the coil-shaped member 2. The need for introducing additional warp threads for presenting a pattern is avoided, and this also contributes to reducing the cost and / or weight of the fastener stringer 1. In addition, the first warp thread 5 and the second warp thread 6 can be fed so that a tension lower than that of the tightening thread is imparted to them, and therefore, due to the spreading of the multifilament yarn or the spun yarn, a pattern can be effectively presented on the upper surface of the upper leg portion 91, or exposure of other yarns (e.g., the tightening thread 7) can be effectively suppressed. In the embodiment, only the second warp thread 6 is woven so that a tension lower than that of the tightening thread is imparted to it.

[0040] The weft portion 3j is straddled by the second warp thread 6 at the top and by the first warp thread 5 at the bottom, and is held between the first and second warp threads 5, 6 at the top and bottom. As a result, the weft portion 3j can be centered between the upper leg portions 91 adjacent in the warp direction. The weft portion 3j may or may not be continuous with the weft thread 3n in the tape main body 32. In the illustrated example, the weft portion 3j is composed of two weft portions aligned in the weft direction and adjacent in the warp direction, but is not limited to this and may be one, three, etc.

[0041] In some cases, the thickness of the first warp threads 5 and the thickness of the second warp threads 6 may be different, which may enhance the appearance of the pattern. In some cases, the first warp threads 5 are thicker than the second warp threads 6. In other cases, the second warp threads 6 are thicker than the first warp threads 5. The first warp threads 5 may include multiple warp threads of different thicknesses. Similarly, the second warp threads 6 may include multiple warp threads of different thicknesses. A subset of the first warp threads 5 may include warp threads that are thicker than the second warp threads 6, and another subset of the first warp threads 5 may include warp threads that are thinner than the second warp threads 6. The thickness of the threads may be measured on the fastener stringer 1 or may be compared on a denier basis.

[0042] To repeat, the fastener tape 3 includes a plurality of fastening threads 7 for fixing the coiled member 2 to the ground structure in addition to the above-mentioned plurality of warp threads 4. The ground structure described here supports the coiled member 2, and in the illustrated example, the above-mentioned lower threads 81 to 88 and the weft threads 3 are included. n By using warp threads other than the tightening thread 7 as the first and second warp threads, one or more problems that may otherwise occur are avoided or suppressed. For example, the following problems are avoided or suppressed: When the tightening thread 7 is used to form a pattern, the pattern may become less dense; As a result of the tension applied to the tightening thread 7, it may be difficult to obtain sufficient bulk and / or width; If the lower thread 8 is not present, the tightening thread 7 may drag the weft thread 3n upward.

[0043] The warp threads 4 may be warp threads of a different thickness from the tightening threads 7, and in the case of a thicker warp thread, the exposure of the tightening thread 7 can be suppressed. When the warp threads 4 are thinner than the tightening threads 7, a design with higher linearity can be obtained. In that case, it is preferable to use multiple sets of the warp threads 4 to suppress the exposure of the tightening threads 7. In addition, the number of the tightening threads 7 is preferably less than the number of the warp threads 4 (the total number of the first and second warp threads 5, 6). This increases the ratio of the warp threads 4 (the first and second warp threads 5, 6) to the tightening threads 7, and the exposure of the tightening threads 7 is more effectively suppressed. Just to be clear, even if all the tightening threads 7 are omitted in the structure shown in Figures 3 to 5, the coil-shaped member 2 can be woven into the fastener tape 3 without any problem.

[0044] In another embodiment, each of the multiple warp threads 4 is a tightening thread 7 for fixing the coiled member 2 to the ground structure. That is, tightening threads 7a, 7b (see FIG. 6) are used (as the first and second warp threads) instead of the first and second warp threads 5, 6 described above. In this case, as can be seen from FIG. 6, the tightening threads 7a and 7b oscillate complementarily and are exposed upward complementarily, so that the same effect as described above can be achieved to the extent that there is no contradiction. Typically, the tightening thread 7 alternately straddles the upper leg 91 of one of the fastener elements 9 adjacent in the warp direction at the top and straddles the lower leg 92 of the other of the fastener elements 9 at the bottom. Preferably, the ground structure includes (typically multiple) lower threads 8 extending in the warp direction in a manner that is inserted between each lower leg 92 of the multiple fastener elements 9 in the coiled member 2 and each weft portion 3j arranged below (for example, directly below) each of these lower leg parts 92. The lower thread 8 prevents the weft thread 3n from being drawn upward by the tightening thread 7. Although not shown in FIG. 6, the weft thread located between the fastener elements 9 may be located in a position sandwiched between the tightening thread and the lower thread 8.

[0045] The pattern of at least two colors presented on the coil-shaped member 2 by the tightening threads 7a, 7b can be formed into a lattice pattern, a dot pattern, and / or a stripe pattern, as described above. The number of tightening threads 7 can be within a range of 3 to 10, such as seven threads in the case shown in Fig. 1. The number of tightening threads 7 can be changed depending on the size of the slide fastener and the thickness of the tightening threads 7.

[0046] In light of the above disclosure, those skilled in the art can make various modifications to each feature and each embodiment. The reference numerals included in the claims are for reference only and should not be used to limit the interpretation of the claims. [Explanation of symbols]
