1 and 2, the fastener tape 100 includes a structure in which warp yarns 10 extending in the front-rear direction and weft yarns 20 extending in the left-right direction are woven. The fastener tape 100 includes a tape main body 112 including a structure in which warps 10 extending in the front-rear direction and wefts 20 extending in the left-right direction are woven. As shown in FIG. 1, the fastener tape 100 has a lateral width W100, a longitudinal length L100, and satisfies W100 <L100. The side edge portion 111 has a left-right width W111, and the tape main body portion 112 has a left-right width W112, which satisfies W111 <W112.

The direction in which the warp 10 extends in the plane on which the fastener tape 100 exists is the tape length direction, and the direction perpendicular to the direction in which the warp 10 extends is the tape width direction. If appropriate or necessary, the front-rear direction referred to in the present specification is read in the tape length direction, and the left-right direction is read in the tape width direction to understand the disclosure of the present specification. These reverse readings are also possible.

In the present embodiment, the tape main body 112 includes one or more barrier portions 30. The barrier portion 30 extends in the direction in which the warp yarn 10 extends, that is, in the tape length direction, and regulates the displacement of the adjacent warp yarns 10 in the tape width direction. The plurality of warp yarns 10 arranged adjacent to the barrier portion 30 include warp yarns 10 that do not adhere to any adjacent warp yarns 10. It can be said that the barrier portion 30 is incorporated in the structure of the warp 10 and the weft 20. The number of the barrier portions 30 provided in the tape main body 112 is not limited to the illustrated example. In some embodiments, the tape main body 112 is provided with 1, 2, 3, 4, 5, 6, 7, or 8 or more barrier portions 30.

1 and 3, first and

second barrier portions

30m and 30n are provided as two barrier portions. The first and

second barrier portions

30m and 30n extend in parallel to the tape length direction while maintaining a constant interval in the tape width direction. Each barrier portion extends linearly in the tape length direction. Therefore, each barrier portion may be called a linear barrier.

In the case shown in FIG. 1, a third barrier portion 30r is optionally provided as a third barrier portion. The third barrier portion 30r is disposed in the vicinity of the fastener element 200. In the vicinity of the fastener element 200, contact between the slider 400 and the fastener tape 100 occurs, and the warp yarn 10 is easily displaced. By providing the above-described third barrier portion 30r in the vicinity of the fastener element 200, such a problem is avoided or reduced, and the durability of the fastener tape 100 is enhanced.

The barrier portion 30 regulates the displacement of the warp yarn 10 adjacent to the left and right in the tape width direction. Therefore, it is allowed to secure a wide arrangement interval of the warps 10 at least in a range adjacent to the barrier portion 30. It is allowed to weave the fastener tape 100 with the reduced number of warps 10, the manufacturing efficiency of the fastener tape 100 can be increased, the weight of the fastener tape 100 can be reduced, or the cost of the fastener tape 100 can be reduced. Or all of this is achieved.

The barrier portion 30 is constructed by fusing the heat fusion yarns 50 adjacent to the left and right in the tape main body portion 112 at a plurality of locations along the tape length direction. The number of heat fusion yarns 50 used to form one barrier portion 30 should not be limited to the illustrated example. Depending on the embodiment, one, two, three, four, five, six, seven, or eight or more thermal fusing yarns 50 are used to form one barrier portion 30. When the fastener tape 100 woven using the heat fusion yarn as the warp yarn 10 is heated, the adjacent heat fusion yarn portions are fused to each other, and as a result, the adjacent heat fusion yarn is partially fixed. Is achieved.

As shown in FIG. 2, the tape main body 112 is configured by intersecting the warp 10 and the weft 20. The tape main body 112 includes a weft set 25 in which wefts 20 extending left and right in the tape width direction are arranged adjacent to each other in the front-rear direction. Each weft set 25 includes two weft portions extending in the tape width direction, and ends with a front weft portion and a rear weft portion. With respect to the weft sets 25 arranged at the front and rear, the left and right outer ends of the front weft portions included in the rear weft set 25 are located at the left and right outer ends of the rear weft portions included in the front weft set 25. It couple | bonds through the folding part not shown.

In the illustrated example of FIG. 2, the tape main body 112 includes a plurality of thermal fusion yarn sets 60, and first and second thermal fusion yarn sets 61 and 62 in order to form a plurality of barrier portions 30. . The first heat-sealing yarn set 61 includes three heat-sealing yarns 50, and ends up including first to third heat-sealing yarns 51 to 53. The second heat fusing yarn set 62 includes three heat fusing yarns 50, and ends up including fourth to sixth heat fusing yarns 54 to 56. In another embodiment, the number of the heat-fusible yarns 50 included in the first heat-fusible yarn set 61 is greater or less than the number of the heat-fusible yarns 50 included in the second heat-welding yarn set 62.

In the illustrated example of FIG. 2, the first heat fusion yarn 51 and the second heat fusion yarn 52 are adjacent to each other in the tape width direction. The second heat fusion yarn 52 and the third heat fusion yarn 53 are adjacent to each other in the tape width direction. The first heat fusion yarn 51 and the third heat fusion yarn 53 are arranged adjacent to each other with the second heat fusion yarn 52 interposed therebetween in the tape width direction. The same relationship applied to the first to third heat fusion yarns 51 to 53 applies to the fourth to sixth heat fusion yarns 54 to 56.

Although not necessarily limited to this, in the illustrated example, each heat-sealing yarn 50 extends in the front-rear direction while lifting and sinking in units of 25 weft sets. The fact that the heat fusion yarn 50 is lifted means that the heat fusion yarn 50 rises from the tape lower surface 102 side to the tape upper surface 101 side. The sinking of the thermal fusion yarn 50 means that the thermal fusion yarn 50 descends from the tape upper surface 101 side to the tape lower surface 102 side.

In the illustrated example, the extending modes in the front-rear direction of the two adjacent heat-bonding yarns 50 are not the same. For example, for the same weft set 25, when the first heat-sealing yarn 51 straddles it on the tape upper surface 101 side, the second heat-sealing yarn 52 straddles it on the tape lower surface 102 side. With respect to the same weft set 25, when the first heat fusion yarn 51 straddles it on the tape lower surface 102 side, the second heat fusion yarn 52 straddles it on the tape upper surface 101 side. It should be noted that it is not always necessary for the two adjacent heat-bonding yarns 50 to rise and fall in a complementary manner.

In the illustrated example, since the two adjacent heat fusion yarns 50 are complementarily raised and lowered, the first heat fusion yarn 51 and the second heat fusion yarn 52 extend so as to appear alternately on the upper surface 101 of the tape, Similarly, it extends so as to appear alternately on the lower surface 102 of the tape. The second heat fusion yarn 52 and the third heat fusion yarn 53 extend so as to alternately appear on the tape upper surface 101 and similarly extend so as to appear alternately on the tape lower surface 102. Since the first heat fusion yarn 51 and the third heat fusion yarn 53 rise and fall in synchronization, the first heat fusion yarn 51 and the third heat fusion yarn 53 appear together on the upper surface 101 of the tape. And so as to appear together on the lower surface 102 of the tape.

In the illustrated example of FIG. 2, the region where the first to third heat fusion yarns 51 to 53 are arranged is called a first heat fusion yarn arrangement region, and the fourth to sixth heat fusion yarns 54 to 56 are arranged. This area may be referred to as a second heat fusion yarn arrangement area. In some embodiments, three or more warp yarns 10 are arranged between the third heat fusion yarn 53 and the fourth heat fusion yarn 54. These three or more warps 10 do not adhere to one or both adjacent warps 10. In the illustrated example, five warp yarns 10 are arranged between the third heat fusion yarn 53 and the fourth heat fusion yarn 54. Each of these five warps 10 does not adhere to one or both adjacent warps 10. A plurality of warp yarns 10 are arranged on the opposite side of the first thermal fusion yarn 51 to the second thermal fusion yarn 52 and the opposite side of the sixth thermal fusion yarn 56 to the fifth thermal fusion yarn 55.

The first heat-fusible yarn 51 has a unit structure of these portions 51a to 51d continuously in the front-rear direction.

The second heat-sealing yarn 52 connects the lower portion 52a straddling the weft assembly 25 on the tape lower surface 102 side, the upper portion 52c straddling the weft assembly 25 on the tape upper surface 101 side, and the lower portion 52a and the upper portion 52c. A first connecting portion 52b extending from the tape upper surface 101 toward the front side, a lower portion 52a and an upper portion 52c are connected, and a second connecting portion 52d extending from the tape upper surface 101 side toward the tape lower surface 102 toward the front side is included. The second heat-bonding yarn 52 is composed of the unit structures of these portions 52a to 52d continuously in the front-rear direction.

The third heat fusion yarn 53 connects the lower portion 53a straddling the weft set 25 on the tape lower surface 102 side, the upper portion 53c straddling the weft set 25 on the tape upper surface 101 side, and the lower portion 53a and the upper portion 53c. A first connecting portion 53b extending from the tape upper surface 101 toward the front side, a lower portion 53a and an upper portion 53c, and a second connecting portion 53d extending from the tape upper surface 101 side toward the tape lower surface 102 toward the front side. The third heat-bonding yarn 53 is composed of the unit structures of these portions 53a to 53d continuously in the front-rear direction.

The description of the first to third heat fusion yarns 51 to 53 applies to the fourth to sixth heat fusion yarns 54 to 56 as well.

1st connection part 51b of the 1st heat fusion yarn 51 and 2nd connection part 52d of the 2nd heat fusion yarn 52 are arranged adjacent to right and left in the tape width direction. Similarly, the second connecting portion 51d of the first heat-sealing yarn 51 and the first connecting portion 52b of the second heat-sealing yarn 52 are arranged adjacent to each other in the tape width direction. The 1st connection part 52b of the 2nd heat-fusion yarn 52 and the 2nd connection part 53d of the 3rd heat-fusion yarn 53 are distribute | arranged adjacent to right and left in a tape width direction.

The second connection portion 52 d of the second heat fusion yarn 52 is sandwiched between the first connection portion 51 b of the first heat fusion yarn 51 and the first connection portion 53 b of the third heat fusion yarn 53. The first connection portion 52 b of the second heat fusion yarn 52 is sandwiched between the second connection portion 51 d of the first heat fusion yarn 51 and the second connection portion 53 d of the third heat fusion yarn 53. The same relationship applied to the first to third heat fusion yarns 51 to 53 applies to the fourth to sixth heat fusion yarns 54 to 56.

As shown in FIGS. 3 and 4, when the fastener tape 100 shown in FIG. 2 is heated, adjacent portions of the heat-sealing yarn in the tape width direction are fused and fixed. Adhering portions formed by adhering portions of adjacent heat-sealing yarns are regularly formed in the tape length direction.

In the fastener tape 100 after heating, each heat fusion yarn 50 partially fixed to the adjacent heat fusion yarn 50 is described as a linear portion of the constituent elements of the barrier portion 30. As can be understood from the comparison between FIG. 2 and FIG. 3, the tape main portion 112 has linear portions 31 to 36 corresponding to the heat fusion yarns 51 to 56. Each of the linear portions 31 to 36 has a basic structure that is the same as that of each of the heat fusion yarns 51 to 56. For example, the first linear portion 31 connects the lower portion 31a straddling the weft assembly 25 on the tape lower surface 102 side, the upper portion 31c straddling the weft assembly 25 on the tape upper surface 101 side, and the lower portion 31a and the upper portion 31c.

As described above, when the adjacent heat-sealing yarn is fused and fixed to form the barrier portion 30, the displacement in the tape width direction of the warp yarn 10 adjacent to the barrier portion 30 in the tape width direction is preferably prevented by the barrier portion 30. Is done. Thereby, it is allowed to reduce the arrangement density of the warps 10 in the region of the tape main body 112 adjacent to the barrier portion 30. As described above, adjacent portions of the heat-sealing yarn are fixed to form a fixing portion, and the fixing portion is arranged in the tape length direction, thereby providing a stronger barrier portion 30.

In some cases, the number of warp yarns 10 in the region R2 between the first barrier portion 30m and the second barrier portion 30n shown in FIG. Less than the number of warps 10 in the region R1 and / or the region R3 adjacent to R2. The region R1 is a region between the second barrier portion 30n and the fastener element 200. The region R3 is a region between the first barrier portion 30m and the side edge portion of the fastener tape 100 where the fastener element 200 is not provided.

In some cases, the arrangement density of the warps 10 in the region R2 is smaller than the arrangement density of the warps 10 in the region R1 and / or the region R3. In other words, the number of warp yarns 10 occupying the unit width in the tape width direction in the region R2 is smaller than the number of warp yarns 10 occupying the same unit width in the tape width direction in the region R1 and / or the region R3.

In some cases, the arrangement density of the warps 10 in the region R3 is equal to the arrangement density of the warps 10 in the region R2. In some embodiments, the arrangement density of the warps 10 at the side edge 111 is equal to the arrangement density of the warps 10 in the region R1.

Simply reducing the number of warp yarns 10 included in the right and left width of the fastener tape results in allowing the left and right displacement of the warp yarns 10 in the tape width direction. Therefore, it is believed that there is an absolute lower limit on the number of warp yarns required for a predetermined width tape. However, it is impossible to increase the manufacturing efficiency of the fastener tape, reduce the weight of the fastener tape, or reduce the cost of the fastener tape only by strictly adhering to the lower limit of the number of warps.

The inventor of the present application introduces a plurality of heat fusion yarns 50 that are selectively adjacent to a group of warp yarns arranged in the left-right direction when the fastener tape 100 is woven using a loom, contrary to the above-mentioned practice. In the heating process after weaving the fastener tape, a plurality of the heat fusion yarns 50 arranged adjacent to each other in the tape width direction are partially fused and fixed, and the lateral displacement of the adjacent warp yarns 10 is restricted. The significance of constructing the possible barrier portion 30 was found.

When the barrier portion 30 is formed on the tape main portion 112, the barrier portion 30 is fixed to the weft 20 or the weft set 25 more strongly than the warp 10. Therefore, the displacement of the warp yarn 10 adjacent to the barrier portion 30 in the tape width direction is suitably restricted. The warp yarns 10 can be arranged sparsely in either the left or right region of the barrier portion 30 or in both regions.

In some embodiments, the number of heat-sealing yarns 50 introduced into the tape main body 112 is smaller than the number of warp yarns 10 of the non-heat-sealing yarn included in the tape main body 112 of the fastener tape 100. . The heat-sealing yarn 50 is usually more expensive than the non-heat-sealing warp yarn 10, and stricter temperature control may be required for storage. In the embodiment example of FIGS. 1 to 3, each barrier portion 30 is composed of three heat-sealing yarns 50, and a total of six heat-sealing yarns 50 are used, which increases the manufacturing cost of the fastener tape. It has been avoided.

In some cases, at least after the heating step, the heat-bonding yarn 50, the barrier portion 30, and / or the linear portion exhibit a color different from that of the warp yarn 10. Thereby, design property can be simultaneously provided to the fastener tape 100. When a plurality of barrier portions 30 different in color from the warp yarn 10 are introduced into the tape main body portion 112, an area in which the fastener tape 100 is sewn to the garment is clearly indicated by the barrier portions 30 that run in parallel at regular intervals in the tape width direction. You can also

The specific configuration and material of the heat-fusible yarn 50 are appropriately determined by those skilled in the art. For example, the heat fusion yarn 50 includes a core and a clad covering the core. The core is made of a heat resistant material. The cladding includes a heat melting material. Alternatively, the heat fusion yarn 50 is a solid linear body made of a heat melting material. The warp yarn 10 is formed by twisting a large number of thin yarns. In this case, the heat fusion yarn 50 is less resistant to the needle than the warp yarn 10. In some cases, the heat fusion yarn 50, the barrier portion 30, and / or the linear portion exhibits a different color from the warp yarn 10, otherwise a needle that allows left-right displacement of the warp yarn 10 adjacent to the barrier portion 30. It is possible to reduce the risk of damage to the barrier portion 30 and the linear portion.

FIG. 5 shows that three sets of adjacent heat-bonding yarn sets 61 to 63 are woven into the tape main body 112 in order to introduce the three barrier portions 30 into the tape main body 112. Even in such a case, the same effect as described above can be obtained. 6 and 7 show an example in which each barrier portion 30 is composed of two heat-sealing yarns 50. Even in such a case, the same effect as described above can be obtained.

FIG. 8 shows an example in which one barrier portion 30 formed from two heat-sealing yarns 50 is introduced into the tape main body 112. Even in such a case, the same effect as described above can be obtained. FIG. 9 shows an example in which adjacent heat-bonding yarns 50 extend back and forth in different modes. Even in such a case, the same effect as described above can be obtained. Specifically, in FIG. 9, the first heat fusion yarn 51 floats and sinks every two weft sets 25, while the second heat fusion yarn 52 rises and sinks every one weft set 25. In this case, the upper part of the first heat fusion yarn 51 straddling the weft set 25 on the tape upper surface 101 side and the upper part of the second heat fusion yarn 52 straddling the weft set 25 on the tape upper surface 101 side are also fused and fixed to each other. .
