Description

Adapter for connection and connection adapter with fastener product

The present invention relates to a connecting adapter for attaching a fastener product such as a slide fastener or a hook-and-loop fastener to a net member such as a bird net or a fish net.

For example, in orchards, bird protection nets are widely used as a bird protection measure. Since the bird nets are generally installed so as to cover the entire fruit tree, there is a problem that the size becomes large and the installation work and the removal work are troublesome.

Therefore, in order to facilitate the installation and removal of the bird net, for example, Japanese Patent Publication No. 58-37816 (Patent Document 1) can be divided into a plurality of nets using a slide fastener. A bird netting that can be assembled by connecting a plurality of nets is disclosed. In addition, the bird net described in Patent Document 1 is provided with an entrance through which a person can go in and out, and a slide fastener is attached to the entrance so that the entrance can be opened and closed.

However, in the bird protection net to which the slide fastener is attached as in Patent Document 1, it is difficult to stably attach the slide fastener to the bird prevention net having a large mesh by sewing or the like.

Moreover, since fishing nets such as stationary nets for fishery and partitioning nets for aquaculture are also formed in a large size, by configuring such a fishing net so that a plurality of nets can be connected and divided using a slide fastener. Often, the installation work and the removal work are facilitated. However, for fishing nets such as stationary nets and partition nets, it has been difficult to stably attach the slide fastener by sewing or the like.

Therefore, in order to make it easy to attach the slide fastener to a net member such as the above-described bird net or fishing net, for example, in Japanese Utility Model Publication No. 61-30490 (Patent Document 2), the slide fastener and the net member are connected. A connecting adapter for doing so is disclosed.

As shown in FIG. 10, the connecting adapter 80 described in Patent Document 2 includes a tape attachment portion 81 for attaching the fastener tape 91 of the slide fastener 90 and a net attachment portion for attaching the net member 95. 82.

The tape attachment portion 81 of the connection adapter 80 includes three thick first warps 83 and wefts 84 that connect the first warps 83 to each other. A plurality of small meshes formed by first warps 83 and wefts 84 are arranged in two rows. Further, the net attachment portion 82 is arranged orthogonally to the thick second warp 85 disposed in parallel with the first warp 83 of the tape attachment portion 81 and the first and second warps 83, 85. And a weft cord 86 for connecting the two warp cords 85 to the tape attachment portion 81. The net attachment portion 82 includes a side edge portion (first warp cord 83) of the tape attachment portion 81 and a second warp cord. A large rectangular opening 87 is formed by the string 85 and the weft string 86.

The connecting adapter 80 is knitted with a chain knitting yarn and several types of weft insertion yarns, and each of the first warp 83 and the second warp 85 has two chain knitting yarns. It is arranged. Further, the weft cord 86 of the net attachment portion 82 is constituted by a weft insertion thread inserted so as to connect the first warp cord 83 and the second warp cord 85 of the tape attachment portion 81.

When attaching the slide fastener 90 to the connecting adapter 80 of Patent Document 2 described above, sewing is performed in a state where the fastener tape 91 of the slide fastener 90 is overlapped with the tape attaching portion 81 of the connecting adapter 80. As a result, the fastener tape 91 is sewn to the weft 84 of the tape attachment portion 81 with the sewing thread. On the other hand, the net member 95 is wound around the second warp 85 of the connection adapter 80 while passing the winding string 96 through each mesh of the net member 95, so that the net attachment portion 82 of the connection adapter 80 is wound. Attached to.

In this way, the fastener tape 91 of the slide fastener 90 is attached to the tape attaching portion 81 of the connecting adapter 80 and the net member 95 is attached to the net attaching portion 82 of the connecting adapter 80 by using the winding string 96, thereby preventing The slide fastener 90 can be stably attached to a net member 95 such as a bird net or a fishing net.

Further, according to Patent Document 2, since a square opening 87 is formed in the net mounting portion 82 of the connecting adapter 80, the connecting adapter 80 is moved in the weft direction (width direction) by the force acting on the net member 95. ), It is difficult to shrink and deform in the warp direction (length direction). For this reason, it is possible to prevent the wavy phenomenon due to the shrinkage from occurring in the slide fastener 90, and it is possible to smoothly perform the sliding operation of the slider in the slide fastener 90.

Further, in Patent Document 2, since a large rectangular opening 87 is formed in the net mounting portion 82 of the connection adapter 80, the fluid resistance can be reduced. For example, the connection adapter 80 is swayed by wind or water flow. The effect that it does not easily occur is also described.

Japanese Patent Publication No.58-37816 Japanese Utility Model Publication No. 61-30490

The connecting adapter 80 as described in Patent Document 2 is generally colored in order to match the color with the slide fastener 90 and the net member 95 and enhance the decoration effect. When coloring the connecting adapter 80, for example, when the connecting adapter 80 is mass-produced, before knitting or weaving the connecting adapter 80, a knitting yarn or a woven yarn used for the connecting adapter 80 is desired. The connecting adapter 80 having a desired color can be manufactured using the dyed knitting yarn or woven yarn.

On the other hand, for example, in the case where the connecting adapter 80 having a desired color is provided to the customer in a small quantity, the connecting adapter 80 is preliminarily used rather than knitting or weaving the connecting adapter 80 after dyeing the knitting yarn or the woven yarn. By knitting or weaving 80 and then dyeing the connecting adapter 80, it is possible to respond to the demand more quickly, and the manufacturing cost of the connecting adapter 80 can be reduced.

However, when dyeing after knitting or weaving the connecting adapter 80 in this way, the shape is fixed in a state where the net mounting portion 82 of the dyed connecting adapter 80 is deformed or distorted with respect to the tape mounting portion 81. As a result, there is a problem that the shape of the opening 87 arranged in the net mounting portion 82 of the connecting adapter 80 is disturbed.

More specifically, for example, when dyeing the knitted or woven connecting adapter 80, the long connecting adapter 80 is supplied to the dyeing apparatus while being continuously conveyed by the conveying roller. The dyeing process is performed while heating the connecting adapter 80. At this time, the coupling adapter 80 conveyed by the conveyance roller is given a tension adjusted to a predetermined size so that the coupling adapter 80 does not loosen during conveyance.

However, as described above, the connecting adapter 80 includes a tape mounting portion 81 in which a plurality of small meshes are arranged in two rows, and a rough net mounting portion 82 in which a large rectangular opening 87 is formed. Have. For this reason, when the long connecting adapter 80 is transported by the transport roller while being applied with tension, the net mounting portion 82 having a rough structure is more greatly affected by the tension than the tape mounting portion 81, and as a result. The dyeing process is performed in a state in which the net attachment portion 82 having a rough structure is deformed or a state in which the tape attachment portion 81 is distorted.

At this time, since the dyeing process is performed while heating the connecting adapter 80, the deformed state or the distorted state of the net mounting part 82 is fixed by the heating in the dyeing process, and the net mounting is performed as described above. The shape of the opening 87 arranged in the portion 82 is disturbed.

And if the shape of the opening 87 of the net mounting portion 82 is disturbed in this way, the appearance (look) of the connecting adapter 80 is impaired. Further, when the net member 95 such as a bird net is attached to the net attachment portion 82 of the connection adapter 80, the winding cord 96 must be wound around the second warp cord 85 while correcting the deformation or distortion of the net attachment portion 82. Therefore, the net member 95 is difficult to attach and the workability of attaching the net member 95 is reduced.

Further, when the net mounting portion 82 of the connecting adapter 80 is deformed or distorted, when the fastener tape 91 of the slide fastener 90 is sewn to the tape mounting portion 81 of the connecting adapter 80, the connecting adapter 80 and the fastener tape 91 are difficult to align, and the connecting adapter 80 and the fastener tape 91 are difficult to sew together with a straight sewing line.

In general, since the conventional connecting adapter is formed in a long length, when the connecting adapter is actually attached to a net member such as a bird net or a fishing net, the slide fastener is cut to a desired length. And a net member is attached. In this case, the conventional connecting adapter has a problem that fraying is likely to occur at the cut end.

In particular, a bird's net or a fishing net using such a connection adapter is subjected to great tension during use. Therefore, sufficient strength and durability are also required for a slide fastener and a connection adapter for connecting net members to each other. However, when fraying occurs at the cut end of the connecting adapter as described above, the strength and durability of the connecting adapter are reduced.

The present invention has been made in view of the above-described conventional problems, and the specific purpose thereof is to stably hold the shape of the net mounting portion even when a dyeing process is performed, It is another object of the present invention to provide a connecting adapter that can prevent fraying at the cut end even when cut at a desired length.

In order to achieve the above object, a connecting adapter provided by the present invention has, as a basic configuration, a tape attachment portion made of a knitted or woven structure and a knitting disposed on one side edge of the tape attachment portion.

And a plurality of horizontal frame portions that connect between the tape mounting portion and the vertical frame portion and are arranged at predetermined intervals in the length direction, and the ear portion on one side edge side of the tape mounting portion A plurality of openings surrounded by the vertical frame portion and the horizontal frame portion are arranged in the length direction, and a fastener product is attached to the tape attachment portion and a net member is attached to the net attachment portion. By doing so, the fastener product and the net member A connection adapter for connecting, to a yarn to be disposed in the lateral frame part which the most important feature to become contains the thermal fusion yarn.

In the connection adapter according to the present invention, the yarn arranged on the ear portion on one side edge side of the tape attachment portion and the vertical frame portion of the net attachment portion contains a heat fusion yarn. Is preferred.
Furthermore, it is preferable that the yarn arranged on the ear portion on the other side edge side of the tape attachment portion includes a heat-sealing yarn.

In the connecting adapter according to the present invention, the heat-sealing yarn has a core-sheath structure, and the core part of the core-sheath structure is made of a non-heat-sealable fiber material, and the sheath part of the core-sheath structure Is preferably made of a heat-fusible fiber material.

Furthermore, it is preferable that the yarn including the heat-sealing yarn is configured by twisting the heat-sealing yarn and the non-fusion yarn.
In this case, it is particularly preferable that the heat-sealing yarn has a fineness of 100T or more and 1100T or less, and the non-heat-sealing yarn has a fineness of 1000T or more and 5000T or less.

In the connection adapter according to the present invention, the tape attachment portion connects the plurality of warp portions arranged between the ear portions on both side edges, and the weft connecting the ear portions and the plurality of warp portions on both side edges. It is preferable that a predetermined gap smaller than the opening is provided between the ear part and the warp part and between the warp part.
In this case, it is particularly preferable that the ear portion is constituted by two warp knitting yarns or warp yarns, and the warp string portion is constituted by one warp knitting yarn or warp yarns.

Further, in the connection adapter according to the present invention, the tape attachment portion and the net attachment portion are made of a knitted structure, and the tape attachment portion is inserted into a chain knitting yarn knitted into a predetermined wale and the entire tape attachment portion. A plurality of first weft insertion threads, a second weft insertion thread to be inserted into the ear portion on the other side edge side, and the vertical weft inserted into the ear portion on one side edge side and through the horizontal frame portion. It is composed of third and fourth weft insertion yarns inserted into the frame portion, the net attachment portion is a chain knitting yarn knitted into the wale of the vertical frame portion, the third and fourth weft insertion yarns, It is preferable that it is constituted by a fifth weft insertion thread inserted into the vertical frame portion.

And the adapter for connection with a fastener product provided by the present invention is mainly characterized in that a hook-and-loop fastener or a slide fastener is attached to the tape mounting portion of the pair of adapters having the above-described configuration. Is.

The connecting adapter according to the present invention has a tape attaching portion to which a fastener product is attached and a net attaching portion to which a net member such as a bird net or a fishing net is attached. The net attachment portion has a strip-like or string-like vertical frame portion arranged along the length direction of the tape attachment portion, and a plurality of horizontal frame portions that connect the tape attachment portion and the vertical frame portion. A plurality of openings surrounded by the ear portion, the vertical frame portion, and the horizontal frame portion of the tape attachment portion are arranged along the length direction. Further, the yarn arranged in the horizontal frame portion of the connecting adapter includes a heat-sealing yarn.

Since the connecting adapter of the present invention includes a heat-sealing yarn having a fixing performance in the horizontal frame portion, the connecting adapter is knitted or woven and then heated to melt the heat-sealing yarn. This makes it possible to fuse and integrate the heat-sealing yarns with each other and to fuse and integrate the heat-sealing yarns with other yarns that form the horizontal frame portion. The shape of the part can be stabilized.

Therefore, even if the connecting adapter that stabilizes the shape of the net mounting portion is subjected to a staining process, it is possible to prevent the net mounting portion having a rough structure from being deformed or distorted during the staining process. It can suppress that the shape of the opening part (mesh) formed in the net attachment part is disturbed. As a result, even if the dyeing process is performed, the appearance of the connecting adapter can be held stably and stably, and the slide fastener and the net member can be easily and stably attached to the connecting adapter.

In the adapter for connection according to the present invention, the heat fusion yarn is included in the yarn arranged in the ear portion on one side edge side of the tape attachment portion and the yarn arranged in the vertical frame portion of the net attachment portion. Thus, the form of the net attachment part can be further stabilized by fusing and integrating the heat fusion yarns and the heat fusion yarns with other yarns.

In addition, the form of the tape attachment part itself is stabilized by fusing and integrating the heat-sealing yarn contained in the ear part on one side edge of the tape attachment part with other heat-fusion yarns and non-heat-fusion yarns. Can be made. For this reason, while being able to hold | maintain the appearance of the adapter for connection more stably, a slide fastener can be stably attached to the tape attachment part of the adapter for connection.

Moreover, when the connecting adapter is cut to a desired length by fusing the heat-sealing yarn included in one side edge of the tape mounting portion and the vertical frame portion of the net mounting portion, Since fraying hardly occurs at the cut end, it is possible to prevent the strength and durability of the connecting adapter from being lowered.

In the connection adapter according to the present invention, the yarns arranged in the ear portion on the other side edge side of the tape attachment portion include a heat fusion yarn, thereby fusing the yarns constituting the ear portion together. Thus, the form of the tape attachment portion itself can be further stabilized. Further, when the connecting adapter is cut to a desired length, fraying at the cut end can be made more difficult to occur.

In the connection adapter of the present invention, the heat-sealing yarn has a core-sheath structure, the core part of the core-sheath structure is made of a non-heat-sealable fiber material, and the sheath part of the core-sheath structure is heat-sealable. It is made of an adhesive fiber material. Thereby, when heat-treating to the connecting adapter, the heat-sealing yarn can be melted, and the core portion of the heat-sealing yarn and the other yarn can be surely fused and integrated.

In this case, the heat fusion yarn has a fineness of 100T (tex) to 1100T (tex), and the non-heat fusion yarn has a fineness of 1000T (tex) to 5000T (tex). When the heat fusion yarn has a fineness of 100 T or more, the heat fusion yarn can be melted and stably fused and integrated with other yarns. Moreover, when the heat-fused yarn has a fineness of 1100 T or less, when the heat-fused yarn is fused and integrated with other yarns, the integrated yarn becomes too hard and brittle. It is possible to appropriately ensure the strength and flexibility of the yarn.

On the other hand, since the non-heat-sealed yarn has a fineness of 1000 T or more, the strength of the yarn including the heat-sealed yarn can be stably secured. In addition, the non-heat-bonded yarn has a fineness of 5000 T or less, thereby suppressing an increase in production cost and preventing the yarn including the heat-bonded yarn from becoming too thick, thereby stabilizing the connecting adapter. Can be knitted or woven.

Further, the fourth weft insertion thread 25 is inserted symmetrically with respect to the third weft insertion thread 24, travels in a zigzag manner over the 15th course of the vertical frame portion 17, and extends from the vertical frame portion 17 to the horizontal frame. It moves to the 2nd ear part 13b via the part 18, and also it travels zigzag over 15 courses for the 2nd ear part 13b, and it is a vertical frame part via the horizontal frame part 18 from the 2nd ear part 13b. 17 is arranged to move.

In the connecting adapter 10 of the present embodiment, a chain knitting yarn 21 disposed on each wale constituting the ear portion 13, the warp portion 14, and the vertical frame portion 17, and a first weft disposed on the tape attachment portion 11. The insertion yarn 22 is a non-heat-bondable twisted yarn (twisted yarn) that is formed by twisting two single yarns made of polyester resin multifilaments. In this case, the fineness of the twisted yarn used for the chain knitting yarn 21 and the first weft insertion yarn 22 is preferably set to 1000 T or more and 2000 T or less in consideration of the strength, flexibility, ease of knitting, etc. In the first embodiment, it is set to 1660T.

Further, as the fifth weft insertion thread 26 to be inserted into the vertical frame portion 17, a single thread made of a polyester resin multifilament is used. The fineness of the single yarn is preferably set to 500T or more and 1000T or less, and is set to 830T in the first embodiment.

On the other hand, the second weft insertion thread 23 disposed in the first ear portion 13a and the third and fourth weft insertion threads 24, 25 disposed in the second ear portion 13b and the net attachment portion 12 are thermally fused. A yarn formed by twisting a yarn and a non-heat fusion yarn is used. In particular, in the first embodiment, each of the second weft insertion yarn 23 to the fourth weft insertion yarn 25 is a composite yarn obtained by twisting one heat fusion yarn and one non-heat fusion yarn. Are formed, and the three composite yarns are further twisted together.

In this case, the heat-sealing yarn is composed of a non-fusible core formed using a high-melting-point high-viscosity polyester, and a copolymer having a lower melting point than the non-fusible core and the non-fusible yarn. It is formed of a core-sheath structure having a fusible sheath portion formed using polyester. Moreover, the single yarn which consists of a polyester resin multifilament is used for the non-heat-bonding yarn.

In this way, if each yarn of the second weft insertion yarn 23 to the fourth weft insertion yarn 25 is formed by twisting a heat-sealing yarn having a core-sheath structure and a non-heat-sealing yarn, By heat-treating the connecting adapter 10 of the embodiment, the sheath portion of the heat-welding yarn is melted and the yarns of the second weft insertion yarn 23 to the fourth weft insertion yarn 25 are fused and integrated. These second weft insertion yarn 23 to fourth weft insertion yarn 25 can be fused and integrated with the chain knitting yarn 21 and other weft insertion yarns intersecting with these weft insertion yarns 23 to 25.

In the present invention, each yarn of the second weft insertion yarn 23 to the fourth weft insertion yarn 25 can be constituted by twisting only the heat fusion yarn having a core-sheath structure, As in the first embodiment, the strength (particularly, the tensile strength) of each weft insertion yarn can be increased by twisting the heat fusion yarn and the non-heat fusion yarn.

More specifically, for example, when each yarn of the second weft insertion yarn 23 to the fourth weft insertion yarn 25 is formed by twisting only the heat fusion yarn, the yarn is melted to obtain another When being fused and integrated with the yarn, each yarn becomes too hard and the flexibility is impaired, and the strength against tensile stress may be reduced. On the other hand, as in the first embodiment, each of the second weft insertion yarn 23 to the fourth weft insertion yarn 25 is formed by twisting a heat fusion yarn and a non-heat fusion yarn. Therefore, even if the yarn is melted and fused and integrated with another yarn, the tensile strength of the yarn can be effectively increased while appropriately securing the flexibility of the yarn.

In the first embodiment, the fineness of the heat fusion yarn in each yarn of the second weft insertion yarn 23 to the fourth weft insertion yarn 25 is set to 100 T or more and 1100 T or less, and the fineness of the non-heat fusion yarn is It is set to 1000T or more and 5000T or less.

As described above, since the fineness of the heat-sealing yarn included in one yarn in the second weft insertion yarn 23 to the fourth weft insertion yarn 25 is set to 100 T or more, the connection adapter 10 has a predetermined size. When heat treatment is performed at a temperature, the weft insertion yarns 23 to 25 themselves can be stably fused and integrated, and the weft insertion yarn and other yarns can be stably fused and integrated. . Further, since the fineness of the heat fusion yarn included in the weft insertion yarns 23 to 25 per one is set to 1100 T or less, the weft insertion yarns 23 to 25 and other yarns are fused and integrated. Even if it is made, the intensity | strength of the said weft insertion thread | yarn can be ensured appropriately, and the softness | flexibility of the adapter 10 for connection can also be ensured appropriately.

Furthermore, since the fineness of the non-heat-sealed yarn included in the weft insertion yarns 23 to 25 per yarn is set to 1000 T or more, the strength of the yarn including the heat-sealed yarn can be stably secured. Further, since the fineness of the non-heat-bonding yarns included in the weft insertion yarns 23 to 25 per yarn is set to 5000 T or less, it is possible to prevent an increase in manufacturing cost. It is possible to prevent the connection adapter 10 from being thickened or hardened, and to stably perform the knitting of the connecting adapter 10.

In addition, as described above, each of the second weft insertion yarn 23 to the fourth weft insertion yarn 25 in the first embodiment includes three heat-sealing yarns and three non-heat-sealing yarns. include. Therefore, in order to set the fineness of the heat fusion yarn and the non-heat fusion yarn in each weft insertion yarn within the above range, the fineness per one heat fusion yarn is set to 280T (that is, one The fineness per weft insertion yarn 23-25 is set to 840T), and the fineness per non-heat fusion yarn is set to 1100T (that is, the fineness per weft insertion yarn 23-25 is 3300T). Set).

The connection adapter 10 according to the first embodiment having the above-described configuration includes the second to second inserts inserted into the first ear portion 13a, the second ear portion 13b, the vertical frame portion 17, and the horizontal frame portion 18. Since the four weft insertion yarns 23 to 25 include heat-sealing yarns, the melting point of the fusible fiber material (copolyester) that forms the sheath portion of the heat-sealing yarn with respect to the connecting adapter 10. Heat treatment is performed at a higher temperature so that the weft insertion yarn itself containing the heat fusion yarn is fused and integrated (that is, the heat fusion yarn constituting the weft insertion yarns 23 to 25 and Non-thermally fused yarn), and weft insertion yarns 23 to 25 including the thermal fusion yarn and other yarns (for example, chain stitch yarn 21 and first weft insertion yarn 22) Can be fused and integrated. Thereby, the form of the tape attachment part 11 and the net attachment part 12 of the connection adapter 10 can be fixed and stabilized.

Therefore, even if the connecting adapter 10 having a stabilized form is subjected to a dyeing process with heating while being transported under tension, the tape attaching part 11 and the net attaching part 12 are deformed during the dyeing process. Or distortion can be effectively prevented. Thereby, the adapter 10 for connection to which the desired color was attached | subjected by the dyeing | staining process and the shape of the opening part 19 of the net attachment part 12 was hold | maintained at the rectangle can be obtained stably. On the other hand, the region sandwiched between the first and second ear portions 13a and 13b in the tape attachment portion 11 of the connecting adapter 10 does not include the heat-sealing yarn, and is composed of only the non-heat-sealing yarn. Therefore, the appropriate flexibility of the tape attachment part 11 can be stably secured.

The connecting adapter 10 according to the first embodiment is formed by twisting together a predetermined number of heat-sealing yarns having a core-sheath structure and a predetermined number of non-fusion yarns as described above. The weft insertion yarns 23 to 25 are configured, but the present invention is not limited to this. For example, as these second to fourth weft insertion yarns 23 to 25 including a heat fusion yarn, for example, heat It is also possible to use a mixed yarn formed by twisting a plurality of filaments made of a fusible fiber material and a plurality of filaments made of a non-heat-fusible fiber material.

Further, the material of the non-heat-bonding yarn is not limited to the polyester resin, and as the non-heat-bonding yarn, for example, a synthetic fiber made of polyamide resin or polypropylene resin, or a natural fiber such as cotton or wool is used. It is also possible.

After the dyeing process, two sets of connecting adapters 10 according to the first embodiment obtained are prepared, and the male surface fastener 30a is attached to the tape mounting portion 11 of one connecting adapter 10. Moreover, the adapter 10 with a pair of hook-and-loop fastener 30 shown in FIG. 2 can be obtained by attaching the female surface fastener 30b to the tape attachment part 11 in the other adapter 10 for connection.

At this time, the method of attaching the male surface fastener 30a or the female surface fastener 30b to the connecting adapter 10 is not particularly limited, but for example, the following method can be used.
That is, the second tape surface of the male surface fastener 30a or the female surface fastener 30b (the tape surface on the side where no engaging element is arranged) is brought into contact with the tape mounting portion 11 of the connecting adapter 10, The fastener 30 and the connecting adapter 10 are overlapped. Then, the overlapped surface fastener 30 and the connecting adapter 10 are stitched together using a sewing machine. Thereby, the hook_and_loop | surface fastener 30 can be attached to the adapter 10 for connection.

In this case, in the connecting adapter 10 according to the first embodiment, the shape of the tape attachment portion 11 is stable because the ear portions 13 are formed on both side edges of the tape attachment portion 11, and the net Since the shape of the attachment portion 12 is not distorted due to the effect of the heat fusion yarn, the hook-and-loop fastener 30 can be easily overlapped with the tape attachment portion 11. Furthermore, the tape attachment portion 11 is provided with a plurality of small meshes 16 as described above, and the three warp portions 14 between the first and second ear portions 13a and 13b are each formed from one wale.
