Description

  The present invention relates to a fastener tape used for a slide fastener, and more particularly, to a textile fastener tape.

  After the woven fastener tape is manufactured, the element is attached to one side edge thereof. Generally, there is a common general knowledge that it is difficult to attach the element when the woven fastener tape is thick. For example, when sewing an element row made of monofilament on a woven fastener tape, if the fastener tape is thick, it is difficult for the needle to pass through, and it is difficult to attach the element row.

  In addition, as an example of a fastener tape, there is a woven fabric in which two types of yarns that can be dyed afterward are used in order to make the front and back surfaces have desired colors (Patent Document 1). More specifically, this fastener tape is a yarn in which a first yarn that can be dyed with a predetermined dye and a second yarn that can be dyed with another dye without being dyed with a dye that dyes the first yarn can be post-dyed. The fabric is woven so that the first yarn is exposed on the front side of the fabric more than the back side and the second yarn is exposed on the back side of the fabric more than the front side. This fastener tape can be dyed with a desired color on the first yarn and the second yarn by an inkjet dyeing method or a spray dyeing method after being formed into a woven fabric, so that the front and back surfaces can have a desired color. Therefore, by dyeing the first yarn and the second yarn in different colors, the fastener tape becomes a woven fabric that exhibits different appearances on the front and back sides.

  However, the fastener tape described above is a post-dyed woven fabric, and therefore has a poor color quality as compared with a woven fabric woven with pre-dyed yarn.

  The fastener tape of the present invention was created in consideration of the above circumstances, and its purpose is to provide a woven fabric in which the element rows are easily attached and the front and back sides have different appearances, and the color is as high as possible. is there.

A fastener tape for a slide fastener of the present invention is a woven fabric including a single woven portion located at one end in the weft direction and a double woven portion adjacent to the single woven portion in the weft direction. The double woven portion includes, as warp threads, a front yarn for exposing on the front side of the double woven portion and a back yarn for exposing on the back side of the double woven portion. On both sides of the part of the back yarn that is exposed on the front side of the double weave section, there is always the part of the front thread that is exposed on the front side of the double weave section. The back yarn is more exposed on the front side of the woven portion, and the back yarn is more exposed on the back side of the double woven portion than the front yarn. The front yarn and the back yarn are dyed yarns of different colors.

In order to visually distinguish the single woven portion and the double woven portion on both the front side and the back side of the fastener tape by color, the following is desirable.
That is, the front yarns and the back yarns of the double woven portion are dyed yarns of different colors from the warp yarns of the single woven portion.

Further, in order to visually distinguish the single woven portion and the double woven portion by the color on only one of the front side and the back side of the fastener tape, the following is desirable.
That is, one of the front yarn and the back yarn of the double woven portion is a dyed yarn of the same color as the warp yarn of the single woven portion, and the other is a dyed yarn of a different color from the warp yarn of the single woven portion.

Further, the double woven portion may have only the front yarn and the back yarn as the warp yarns, but in order to reinforce the durability of the woven fabric, the following is desirable.
That is, the double woven portion is provided with a reinforcing thread in addition to the front yarn and the back yarn as the warp, and the reinforcing yarn is exposed to the back side of the double woven portion more than the front yarn, and the front side of the double woven portion is larger than the back yarn. Is to be exposed to a lot.

The density of the warp and the weft in the double weave is not limited, but the color of the double weave reflects the color of the warp rather than the color of the weft so that the single weave and the double weave can be easily distinguished by color. , It is desirable to do the following.
That is, the density of the warp yarns in the double weave portion is higher than the density of the weft yarns.

The densities of the warp yarns of the single woven portion and the double woven portion are not limited, but the following is preferable in order to make it easy to distinguish the single woven portion and the double woven portion in terms of appearance.
That is, the density of the warp yarns in the double woven portion is higher than the density of the warp yarns in the single woven portion.

  According to the fastener tape of the present invention, the thickness of the single woven portion is smaller than that of the double woven portion, and since the single woven portion having the smaller thickness is provided at one end in the weft direction, the element row can be easily attached to the single woven portion. Further, since the pre-dyed yarn is used for the warp yarn of the double woven portion, the color of the fastener tape (double woven portion) becomes high quality as compared with, for example, the case where the warp yarn is dyed after forming a woven fabric. Also, the color of the front thread affects the appearance on the front side of the double weave section, and the color of the back thread on the back side of the double weave section affects the appearance. become.

  In addition, with the fastener tape in which the front and back threads of the double woven portion are dyed yarns of different colors from the warp threads of the single woven portion, the single woven portion and the double woven portion are colored in appearance on both the front and back sides of the fastener tape. Can be distinguished.

  Further, according to the fastener tape, one of the front yarn and the back yarn of the double woven portion is a yarn-dyed yarn of the same color as the warp yarn of the single-woven portion, and the other is a yarn-dyed yarn of a different color from the warp yarn of the single-woven portion. Only one of the front side and the back side of the tape can distinguish the single woven part and the double woven part by color.

  Further, according to the fastener tape including the reinforcing yarn in addition to the front yarn and the back yarn as the warp yarn of the double woven portion, the reinforcing yarn is exposed to the back side of the double woven portion more than the front yarn, and the double woven portion is more exposed than the back yarn. Since it is exposed a lot on the front side, the strength as a woven fabric is improved and the thickness as a woven fabric is reduced as compared with, for example, a double woven portion in which only front yarns and back yarns are used as warp yarns.

  Also, with a fastener tape in which the density of the warp yarns in the double woven portion is made higher than that of the weft yarns, the color of the double woven portion appears more than the color of the weft yarns, and the single woven portion and the double woven portion are colored. It becomes easy to distinguish the appearance.

  Also, with a fastener tape in which the density of the warp yarns in the double woven portion is higher than that of the single woven portion, the warp yarns in the double woven portion are easier to see than in the single woven portion, and the single woven portion and the double woven portion can be visually distinguished by color. It will be easier.

  The fastener tape T according to the first embodiment of the present invention is a woven fabric. In describing the present invention, directions are determined as follows. The “warp direction” is a direction in which the warp yarns of the warp yarns and the weft yarns constituting the fabric are extended when the fabric is viewed from the thickness direction. The “weft direction” is the direction in which the weft extends when the woven fabric is viewed from the thickness direction. Since FIG. 4 shows the entire slide fastener 20, warps and wefts are not shown, but in FIG. 4, the warp direction is the vertical direction and the weft direction is the horizontal direction. FIG. 1 shows a fastener tape T according to a first embodiment of the present invention, in which warp yarns Y and weft yarns X are shown. In FIG. 1, the warp direction is the vertical direction and the weft direction is the horizontal direction. . The “front side” is one side in the thickness direction of the woven fabric, and in FIGS. 1 and 4, it is the paper side, more specifically, the visible side. The “back side” is the other side in the thickness direction of the woven fabric, and in FIGS. 1 and 4, it is the back side of the paper surface, more specifically, the invisible side.

  As shown in FIGS. 1 and 4, the fastener tape T according to the first embodiment of the present invention is a woven fabric in which a single woven portion T1, a double woven portion T2, and a single woven portion T1 are continuously arranged in the weft direction in order. It was woven in. In other words, the fastener tape T of the present embodiment includes the single woven portions T1 at both ends in the weft direction, and the double woven portions T2 adjacent to each other between the two single woven portions T1 and T1. One of the two single woven portions T1 and T1 is a portion to which the element row E is attached by sewing. The other is a portion to be attached to an object such as clothing by sewing. Hereinafter, the single woven portion T1 and the double woven portion T2 will be described in detail.

In addition to the fastener tape T, FIG. 1 shows an enlarged view of a part of the fastener tape T. In this enlarged view, a method of combining the warp yarns Y and the weft yarns X is expressed. In the enlarged view, the warp Y is shown by three types of thick lines and the weft X is shown by one type of lines in order to clarify how to combine them.
The three types of thick lines indicating the warp Y are a thick black solid line (hereinafter, referred to as “black line”) and a line in which black dots are scattered between two parallel solid lines (hereinafter, “polka dot pattern”). Line)), and a line in which parallel diagonal lines are arranged at equal intervals between two parallel solid lines (hereinafter, referred to as a “diagonal line”). The line indicating the weft yarn X is a line in which the space between two parallel solid lines is white (hereinafter, referred to as “white line”).
In FIG. 1, the middle portion of the left single-woven portion T1 in the weft direction is omitted, the right-side portion of the double-woven portion T2 is omitted, and the right-side portion of the right single-woven portion T1 is omitted.

  The single woven portion T1 is a woven fabric composed of a single warp and a weft. The single woven portion T1 may have any design, such as a plain weave design, a twill weave design, and a satin weave design. By the way, in FIG. 1, the warp yarns of the single woven portion T1 are shown by a polka dot line, and the reference numeral Y0 is added.

The double weave portion T2 is any of a warp double weave, a weft double weave, and a warp double weave.
The warp double woven fabric is a woven fabric composed of a single weft yarn X and double front and back warp yarns Y, Y with respect to the single weft yarn X.
A weft double woven fabric is a woven fabric composed of a single warp yarn Y and double weave yarns X and X for the single warp yarn Y.
The warp / weft double weave is a woven fabric in which both the warp Y and the weft X are double.

In the present embodiment, the double weave portion T2 is a warp double weave, and uses three types of yarns for the warp Y and one type of yarn for the weft X.
The first type of warp yarn Y is a yarn to be exposed on the front side of the double weave portion T2, that is, the front yarn Y1. The second type of warp yarn Y is a yarn to be exposed on the back side of the double weave portion T2, that is, a back yarn Y2.
The front yarn Y1 is more exposed to the front side of the double woven portion T2 than the back yarn Y2. More specifically, in the present embodiment, the front yarn Y1 is more exposed to the front side than the back side of the double woven portion T2, The yarn is located on the front side of the weft yarn X in a large amount. Therefore, the length of the front yarn Y1 located on the front side of the weft X is longer than the length of the front yarn Y1 located on the back side. The front yarn Y1 is a black line in the enlarged view of FIG.
The back yarn Y2 is more exposed to the back side of the double woven portion T2 than the front yarn Y1, and more specifically, in the present embodiment, it is a yarn exposed to the back side more than the front side of the double woven portion T2. The yarn is located on the back side of the weft yarn X in a large amount. Therefore, the length of the back yarn Y2 located on the back side of the weft yarn X is longer than the length of the back yarn Y2 located on the front side of the weft yarn X. In the enlarged view of FIG. 1, it is a diagonal line.
The third type of warp yarn Y is a yarn for reinforcing the durability as a woven fabric, that is, a reinforcing yarn Y3, as compared with a double woven portion using only the front yarn Y1 and the back yarn Y2 as the warp yarn Y. The reinforcing yarn Y3 is exposed to the back side of the double woven portion T2 more than to the front yarn Y1, and more exposed to the front side of the double woven portion T2 than the back yarn Y2. More specifically, in the present embodiment, It is a thread that is exposed equally on the front and back sides of the fabric. In the enlarged view of FIG. 1, it is a polka dot line.

  FIG. 2 shows a schematic view showing the double weave portion T2 in an enlarged manner in the part of the schematic view of FIG. In the example of FIG. 2, eighteen warp yarns Y are shown in the weft direction, and each warp yarn Y is sequentially numbered from the left side to the right side in the drawing by numbers 1 to 18 surrounded by a circular frame (○). Is also written. Further, sixteen wefts X are shown in the warp direction, and the numbers 1 to 16 surrounded by a square frame (□) are also written on each weft X in order from the lower side to the upper side in the drawing. There is. Of the warp yarns Y, the front yarn Y1 is the warp yarn Y of Nos. 1, 3, 5, 7, 10, 12, 14, and 16. Among the warp yarns Y, the back yarn Y2 is the second, fourth, sixth, eighth, eleventh, thirteenth, thirteenth, seventeenth, and seventeenth warp yarns Y, and of the warp yarns Y, the reinforcing yarn Y3 is the ninth and eighteenth warp yarn Y. In FIG. 2, the number of the warp yarns Y of the double weave portion T2 is 18, but in the present embodiment, it is assumed to be 35, and as shown in FIG. 1, of the warp yarns Y of the single weave portion T1 with respect to the double weave portion T2. The warp yarn Y on the left side in the weft direction is the 0th warp yarn Y0, and the warp yarn Y on the right side is the 36th warp yarn Y0.

  As shown in FIGS. 2 and 3 (A), the front yarn Y1 is woven by repeating the same weaving process for every eight weft yarns X. The No. 1 and No. 5 surface yarns Y1 overlap the eight weft yarns No. 1 to 8 on the front side of the six weft yarns No. 1 to 6 and the two weft yarns No. 7 to 8 It is woven so that it overlaps with the back side of X, and this weave is also woven with respect to the next eight weft yarns No. 9 to 16. The No. 3 and 7 front yarns Y1 overlap the No. 1 to No. 8 eight weft yarns X on the front side of the six No. 1, 2, 5 to 8 weft yarns X, and the No. 3 and No. 4 yarns. The two wefts X are woven so as to be overlapped with each other so as to overlap with the back side, and this weave is also used for the next eight wefts X of Nos. 9 to 16.

  The back yarn Y2 of the warp yarns Y is also woven by repeating the same weaving process for every eight weft yarns X, as shown in FIGS. 2 and 3A. The No. 2 and No. 6 back yarns Y2 are woven so as to overlap with the back side of the six wefts No. 1 to 4, 7, and 8 and to overlap with the front side of two No. 5 to 6 wefts X. With this weave method, the following eight weft yarns No. 9 to 16 are also woven. The No. 4 and No. 8 back yarns Y2 are woven so as to overlap with the front side of the two No. 1 and No. 2 weft yarns X and overlap with the back side of the No. 3 to No. 6 six weft yarns X. On the other hand, it is also woven for the following eight weft yarns No. 9 to 16. The front yarn Y1 and the back yarn Y2 occupy most of the warp yarns Y constituting the double woven portion T2, and are used in the same number in the double woven portion T2.

  As shown in FIGS. 2 and 3A, among the warp yarns Y, the reinforcing yarn Y3 occupies a very small part of the warp yarns Y constituting the double weave portion T2, and has a space in the middle portion in the weft direction of the double weave portion T2. It is arranged with a gap. The reinforcing yarn Y3 is woven by repeating the same weaving process for every four yarns. The 9th reinforcing yarn Y3 is woven so as to overlap with the back side of the 1st to 2nd wefts X and also to overlap with the front sides of the 3rd and 4th wefts X. It is also woven with respect to the four weft yarns # 8.

The double weave portion T2 is provided with a plurality of sets (four sets in this embodiment) in which the front yarns Y1 and the back yarns Y2 are alternately arranged in the weft direction and are spaced from each other in the weft direction. It is a woven fabric including a reinforcing yarn Y3. In this embodiment, the reinforcing yarn Y3 is the warp yarn Y3 of Nos. 9, 18, and 27 as shown in FIG. The warp yarns Y located on both sides of the double weave portion T2 are the warp yarns Y0 of the two single weave portions T1 and T1, and are the warp yarns Y0 and No. 36 of FIG. 1, which are the warp yarns 0 and 36. As shown in FIGS. 2 and 3B, Y0 is also woven by the same weave as the reinforcing yarn Y3.
The 38th warp yarn Y0 of the single woven portion T1 is woven by repeating the same weave every eight yarns. The No. 38 warp yarn Y0 is woven so as to overlap with the back side of the weft yarns X of Nos. 1, 2, 7, and 8 and to overlap with the front side of the two weft yarns No. 3 to 6 with this weave. It is also woven for the following eight weft yarns 9 to 16.

  Further, the fastener tape T of the first embodiment of the present invention has a double weave portion T2 in which the weft yarn X is folded back at least at one end of the fabric when the fabric is woven, and more specifically, at least twice each. It is formed by passing it through a shed, and as a result, it is woven so that at least two units of weft yarns X are overlapped with warp yarns Y on the front side or the back side thereof. Incidentally, the shed is a gap formed by the warp yarns Y by vertically moving a large number of warp yarns Y by a loom, and is for passing the weft yarns X.

  The front yarn Y1 appears on the front side and the back side of the double woven portion T2 at a ratio of 6: 2, and the back yarn Y2 appears on the front side and the back side of the double woven portion T2 at a ratio of 2: 6. That is, both the warp yarn Y and the weft yarn X are present on the front side of the woven fabric. Therefore, considering only this, both the front yarn Y1 and the back yarn Y2 have a ratio of 6: 2 for the front side of the double weave portion T2. It seems to exist in. However, in reality, it seems that only the front yarn Y1 is present regarding the appearance of the front side of the fabric, and only the back yarn Y2 is present regarding the appearance of the back side of the fabric. In the following, the causes for the appearance of the front side of the fabric will be described, and the causes for the appearance of the back side will be omitted.

  Since the front yarn Y1 is overlapped on the front side of the adjacent “six” wefts X, the length of the front yarn Y1 in this portion is sufficiently longer in the warp direction than in the weft direction. Then, the weft yarn X is strongly restrained at both ends in the warp direction of the front yarn Y1, but the weft yarn X is weakly restrained in the middle portion in the warp direction, and the front yarn Y1 spreads in the weft direction. On the other hand, since the back yarn Y2 is overlapped on the front side of the adjacent "two" wefts X, the back yarn Y2 does not have much difference in the warp direction and the weft direction at this portion, and therefore in the weft direction. It becomes a straight line with almost no spread. Therefore, the ratio of the front yarn Y1 and the back yarn Y2 existing on the front side of the double weave portion T2 is not 6: 2, but a larger proportion is corresponding to the portion where the front yarn Y1 spreads in the weft direction. Will be occupied.

  Further, due to the above-mentioned constraint of the weft yarn X, the front yarn Y1 not only spreads in the weft direction at the intermediate portion in the warp direction, but also spreads in the overlapping direction of the warp yarn Y and the weft yarn X. On the other hand, the back yarn Y2 is in a straight line state with almost no spreading even in the overlapping direction of the warp yarn Y and the weft yarn X. Therefore, the front yarn Y1 is positioned closer to the front side than the back yarn Y2 as it goes to the middle portion in the longitudinal direction, and the front yarn Y1 is more easily visually recognized than the back yarn Y2.

  In the needle loom, the tension of the weft yarn X is higher than that of the warp yarn Y at the time of manufacturing (two adjacent weft yarns X, X are bent at one end side in the weft direction of the fabric as shown in the enlarged view of FIG. 1). When the woven fabric is laid on a plane, all wefts X appear to be on the same plane. Therefore, the front yarn Y1 is superposed on the front side of a large number of weft yarns X existing on the same plane, and the front yarn Y1 is conspicuous, but the weft yarn X is not conspicuous. Since the front yarn Y1 is spread in the weft direction, the weft X is covered with the front yarn Y1, and the weft X is less noticeable.

  The density of the warp yarns Y in the double weave portion T2 is made higher than the density of the weft yarns X. As a specific example, the thickness of each of the warp Y and the weft X is 330 T, the density of the warp Y is 220 / inch, and the density of the weft X is 98 / inch. Therefore, the ratio between the density of the warp Y and the density of the weft X is 220: 98 = 2.24: 1. By setting the density ratio of the warp yarns to 2.24 or more, the weft yarns X are less noticeable in the double weave portion T2 in the present embodiment.

  Moreover, the relationship between the one back yarn Y2 and the two front yarns Y1 on both sides thereof is as follows. There is always a portion of the front yarn Y1 located on the front side of the double weave portion T2 on both sides of the portion of the back yarn Y2 located on the front side of the double weave portion T2. More specifically, this relationship includes not only the back yarn Y2 of No. 2 but also the front yarn Y1 of No. 1 and No. 3 on the front side of the weft yarns No. 5 and 6. Therefore, the presence of the back yarn Y2 is less noticeable in the double weave portion T2 in the present embodiment.

  Due to the above reasons, in terms of appearance, only the front yarn Y1 seems to be present on the front side of the double woven portion T2.

  In the fastener tape T of the first embodiment of the present invention, the warp yarns Y and the weft yarns X are yarns dyed before weaving with a loom, that is, pre-dyed yarns, and among the warp yarns Y of the double weave portion T2. As the front yarn Y1, the back yarn Y2, and the warp yarn Y0 of the single weave portion T1, different dyed yarns are used. More specifically, the warp yarns Y0 of the two single woven portions T1 located on both sides of the double woven portion T2, the reinforcing yarn Y3 of the warp yarns Y2 of the double woven portion T2, and all the weft yarns X have the same color. A yarn-dyed yarn is used, and the yarn-dyed yarn having a different color from the yarn-dyed yarn is used for the front yarn Y1 and the back yarn Y2 of the warp yarn Y of the double woven portion T2. Of the warp yarns Y of the double weave portion T2, the front yarn Y1 and the back yarn Y2 are also pre-dyed yarns of different colors.

As described above, as to the outer appearance of the double woven portion T2, only the front yarn Y1 seems to be present on the front side of the double woven portion T2. Therefore, regarding the outer appearance of the double woven portion T2, the fastener tape according to the first embodiment of the present invention is used. As shown in FIG. 1, T only appears as if the double woven portion T2 exists in a straight line extending in the warp direction between two single woven portions T1 of the same color located on both sides of the double woven portion T2. Instead, it is seen in a color different from the color of the single woven portion T1 (color of the front yarn Y1). As shown in FIG. 4, the fastener tape T of the present embodiment looks like a design in which a narrow line extends in the longitudinal direction along the element row E of the fastener tape T.
Also, although not shown, regarding the appearance on the back side as well, the fastener tape T of the first embodiment of the present invention has a double woven portion T2 between two single woven portions T1 of the same color located on both sides of the double woven portion T2. Not only appear to be present in a thick straight line extending in the warp direction, but also appear in a color different from the color of the single weave portion T1 (color of the back yarn Y2).
Further, for example, the front yarn Y1 of the double woven portion T2 is a yarn-dyed yarn of a different color from the warp yarn Y0 of the single woven portion T1, and the back yarn Y2 of the double woven portion T2 is a yarn of the same color as the warp yarn Y0 of the single woven portion T1. In this case, on the front side of the fastener tape T, it seems that the double woven portion T2 exists between the two single woven portions T1 of the same color located on both sides of the double woven portion T2 in the shape of a thick straight line extending in the longitudinal direction. Not only that, but the color is different from the color of the single woven portion T1 (the color of the front yarn Y1). On the other hand, on the back side of the fastener tape T, the color difference between the single woven portion T1 and the double woven portion T2 cannot be confirmed. Therefore, only on the front side of the fastener tape T, the double woven portion T2 seems to exist in a thick straight line extending in the warp direction with a color different from that of the single woven portion T1.

  The fastener tape T of the present embodiment uses pre-dyed yarns not only for the warp yarns Y of the double weave portion T2 but also for the warp yarns Y of the single weave portion T1. For example, the color of the fastener tape T becomes high quality. Further, the color of the front yarn Y1 affects the appearance on the front side of the double woven portion T2, and the color of the back yarn Y2 affects the appearance on the back side of the double woven portion T2. And the back side has a different appearance.

  In the fastener tape T of the first embodiment of the present invention, the density of the warp yarns Y in the double weave portion T2 is made higher than the density of the warp yarns Y0 in the single weave portion T1. As described above, in the double weave portion T2, the ratio of the density of the warp Y to the density of the weft X is 2.24: 1. Assuming the density ratio of the double woven portion T2, the ratio of the density of the warp yarns Y of the double woven portion T2 to the density of the warp yarns Y0 of the single woven portion T1 is set to 1.61: 1. Therefore, the density of the warp yarns Y in the double weave portion T2 is higher than the density of the warp yarns Y0 in the single weave portion T1, so that the double weave portion T2 is easier to see the warp yarns Y than the single weave portion T1 (the weft yarns X are less visible), and the single weave yarns are The woven portion T1 and the double woven portion T2 can be easily distinguished from each other by their colors.

  In the fastener tape T of the first embodiment of the present invention, the element row E is attached to the single woven portion T1, the thickness of the single woven portion T1 is smaller than that of the double woven portion T2, and the warp threads of the double woven portion T2. Since the density of the warp yarns Y0 of the single woven portion T1 is smaller than the density of Y, it is easy to attach, for example, as the element row E when sewing a coiled monofilament.

  Further, the fastener tape T according to the first embodiment of the present invention includes a reinforcing yarn Y3 in addition to the front yarn Y1 and the back yarn Y2 as the warp yarns Y of the double weave portion T2. Since it is exposed more on the back side of the heavy weave portion T2 and more on the front side of the double weave portion T2 than on the back yarn Y2, for example, compared to a double weave portion in which only the front yarn Y1 and the back yarn Y2 are warp yarns Y, The durability as a woven fabric is improved. Moreover, in the fastener tape T of the first embodiment of the present invention, since the plurality of reinforcing yarns Y3 are arranged at intervals in the weft direction of the fabric, only the front yarn Y1 and the back yarn Y2 are used as warp yarns Y. The thickness of the woven fabric is smaller than that of the heavy woven portion.

  The present invention is not limited to the above-described embodiment, and can be modified as appropriate without departing from the spirit of the present invention. The double weave portion T2 is not limited to the warp double weave as described above, but may be a weft double weave or a warp double weave. Further, in the present embodiment, the front yarn Y1, the back yarn Y2, and the reinforcing yarn Y3 are used for the double weave portion T2, but the present invention is not limited to this, and the double weave portion T2 uses only the front yarn Y1 and the back yarn Y2. May be

In the case of a warp-weft double weave, the double weave portion T2 includes a front-side single-woven fabric composed of only the front yarn Y1 and the weft X, and a back-side single-woven fabric composed of only the back yarn Y2 and the weft X. May overlap with each other, or a reinforcing yarn Y3 for reinforcing the durability of the double woven portion T2 as a woven fabric may be used, and the woven fabric on the front side at an appropriate position in the weft direction of the double woven portion T2. It is also possible to connect the fabric on the back side with the reinforcing yarn Y3. The reinforcing yarn Y3 may be one or more of the total number of front yarns Y1 or the total number of back yarns Y2 forming the double woven portion T2, and may also be used as the reinforcing yarn Y3. The total number of front yarns Y1 and back yarns Y2 forming the woven portion T2 may be completely different yarns, and dedicated binding yarns for joining the front side fabric and the back side fabric may be used. In this case as well, the reinforcing yarn Y3 is more exposed to the back side of the double woven portion T2 than the front yarn Y1, and more exposed to the front side of the double woven portion T2 than the back yarn Y2.
By the way, when the front side fabric and the back side fabric are simply overlapped with each other, the front yarn Y1 is exposed only on the front side of the fastener tape T and is not exposed at all on the back side, and the back yarn Y2 is the back side of the fastener tape T. Only exposed to the outside, not exposed to the front side at all. Also in this case, the front yarn Y1 is more exposed to the front side of the double weave portion T2 than the back yarn Y2, and the back yarn Y2 is more exposed to the back side of the double weave portion T2 than the front yarn Y1.
