Abstract

The fastener tape (21, 41, 61) of this fastener stringer (20, 40, 60) extends beyond the edge of the fastener elements (23, 43, 63) on the connecting part (23d, 43d, 63d) side. The length (X) of the extension thereof is kept less than 12 mm. When the fastener stringer (20, 40, 60) is curved in the direction of the fastener tape (21, 41, 61) width, local bunching, etc. of the tape extension part (25, 45, 65) of the fastener tape (21, 41, 61) can thereby be effectively inhibited. Consequently, the fastener stringer (20, 40, 60) can be stably sewn while keeping the tape extension part (25, 45, 65) substantially flat even if the fastener tape (21, 41, 61) is curved. Moreover, reduced quality of appearance is prevented because it is difficult for bunching, etc. of the sewn fastener tape (21, 41, 61) to occur.

Description

Fastener stringers and slide fasteners

The present invention relates to a slide fastener attached to, for example, a seat cover for an automobile seat or a seat cover for a sofa, and in particular, even if the slide fastener is bent in the tape width direction of the fastener tape, the fastener tape is lifted or sinked. The present invention relates to a slide fastener that is less likely to cause the problem.

Conventional slide fasteners are roughly classified into two types: normal type slide fasteners and hidden type slide fasteners. A normal type of slide fastener is attached to the opposing element mounting part of a pair of fastener tapes with the fastener element protruding outward from the tape side edge on the element mounting part side. It is configured. Such a normal type slide fastener is generally in a state in which at least a part of the fastener element is exposed to the outside when the left and right fastener elements are engaged with each other.

On the other hand, hidden type slide fasteners (hereinafter simply referred to as “hidden slide fasteners”) are configured such that when the left and right fastener elements are engaged, the fastener elements can be hidden from view from the outside. Then, from the viewpoint of design, it is increasingly used in the fields of clothes and shoes.

An example of such a hidden slide fastener is disclosed in, for example, Japanese Patent Application Laid-Open No. 2008-119096 (Patent Document 1). As shown in FIG. 9, the hidden slide fastener 80 described in Patent Document 1 is a so-called woven type in which the fastener element 83 is attached to the fastener tape 82 at the same time as the fastener tape 82 is woven. The hidden slide fastener 80 of FIG.

More specifically, the hidden slide fastener 80 of Patent Document 1 has a pair of left and right fastener stringers 81 and a slider (not shown). Each of the left and right fastener stringers 81 includes a pair of right and left belt-like fastener tapes 82 woven and a coil-like fastener element 83 woven into the fastener tape 82.

The fastener tape 82 includes a tape main part 82a to be sewn on a fastener-attached product such as clothes, and a tape bent part that extends from one side edge of the tape main part 82a in the tape width direction and is bent in a U shape. 82b, and an element attachment portion 82c extending further from the tape bent portion 82b and into which the fastener element 83 is woven.

The fastener element 83 is formed in a continuous shape by molding a monofilament made of synthetic resin into a coil shape, and has a massive meshing head 83a formed by pressing the monofilament at predetermined intervals, and a meshing head It has upper and lower leg portions 83b and 83c extending in the tape width direction from 83a and a connecting portion 83d for connecting the adjacent fastener elements 83 to each other.

In this case, the fastener element 83 is woven into the element attachment portion 82c at the same time that the upper and lower leg portions 83b and 83c are woven with the engagement head 83a facing the inside of the fastener tape 82. Has been attached to. Furthermore, after weaving the fastener tape 82, the fastener tape 82 is folded back in a U-shape in the region of the tape bent portion 82b so that the meshing head 83a of the fastener element 83 protrudes outward from the tape bent portion 82b. The fastener stringer 81 is manufactured by performing heat setting in the state. And the hidden slide fastener 80 shown in FIG. 9 is obtained by combining the obtained fastener stringer 81 in a pair.

In particular, in the fastener stringer 81 described in Patent Document 1, a plurality of upper fixing members that run on the outer surfaces of the upper leg portion 83b and the lower leg portion 83c of the fastener element 83 are disposed on the element mounting portion 82c of the fastener tape 82, respectively. A plurality of tightening warps that cross in the warp 84a and the lower fixing warp 84b and the upper and lower leg portions 83b, 83c of the element and run in the warp direction so as to alternately straddle the upper leg portion 83b and the lower leg portion 83c. 84c. In addition, among the plurality of lower fixing warps 84b, the total fineness of the lower fixing warps 84b traveling on the side of the meshing head 83a of the element relative to the fastening warps 84c is greater than the meshing head 83a than the fastening warps 84c. It is configured to be larger than the total fineness of the upper fixing warp 84a traveling on the side.

As a result, the plurality of lower fixing warps 84b traveling closer to the meshing head 83a side than the tightening warps 84c are densely arranged, so that the hidden slide fastener 80 is left and right when the left and right fastener elements 83 are engaged. Even when a strong lateral pulling force is applied in the direction of separating the fastener tapes 82 from each other, the position of the lower fixing warp 84b can be prevented from shifting. For this reason, it can prevent effectively that a clearance gap arises between the tape bending parts 82b of the right and left fastener tapes 82, and can maintain the excellent concealment property of the hidden slide fastener 80.

JP 2008-119096 A

In recent years, hidden slide fasteners have been used not only for products such as various clothes and shoes, but also for various products such as seat covers for automobile seats and seat covers for sofas, taking advantage of their advantages. Yes. For this reason, the hidden slide fastener is desired to be configured to be usable in various environments and conditions.

For example, when a hidden slide fastener is used for a seat cover of an automobile seat, the automobile seat is configured such that a cushion body formed in a predetermined shape is covered with the seat cover. In this case, depending on the shape of the automobile seat, the hidden slide fastener may be attached to the seat cover in a state where the hidden slide fastener is curved in the tape front / back direction or the tape width direction. In addition, the hidden slide fastener may be attached to the seat cover by actively curving the hidden slide fastener in the tape front / back direction or the tape width direction for the convenience of designing the automobile seat.

By the way, since the fastener tape used for the slide fastener is woven or knitted, it is usually thin in the thickness direction (thickness dimension is small), and the slide fastener is stable to a fastener-attached product using a sewing machine. In order to perform sewing, the width direction is wide (the width dimension is large). Specifically, for example, in the case of a conventional normal type slide fastener or a hidden slide fastener, the thickness dimension of the fastener tape is set to 1 mm or less, while the width dimension of the fastener tape is various fastener-attached products. On the other hand, the width dimension of the tape extending portion is generally set to be 12 mm or more so that the sewing can be performed smoothly.

Here, the tape extending portion is a portion of the tape region that is exposed to the outside of the connecting portion of the fastener element when the fastener stringer is viewed from the fastener element side, and the tape width of the tape extending portion is The larger the dimension in the direction, the more accurately the fastener tape can be pressed with the sewing machine foot when sewing with the sewing machine, so that the sewing can be performed stably.

As described above, in the conventional slide fastener, the fastener tape is thin in the thickness direction and wide in the width direction (particularly, the tape extending portion can ensure a size of 10 mm or more). For this reason, for example, when a hidden slide fastener is bent in the tape front and back direction and attached to a fastener-attached product such as a seat cover, the fastener tape itself is folded relatively easily in the thickness direction (front and back direction). Therefore, the hidden slide fastener can be beautifully sewn to the fastener-attached product.

On the other hand, for example, when the hidden slide fastener is bent in the tape width direction and attached to a fastener-attached product such as a seat cover, the outer peripheral side of the hidden slide fastener is bent when the fastener tape is bent in the tape width direction. The tape extension that hits (the tape extension that curves in a convex shape) may partially rise or sink, and the tape extension that hits the inner periphery of the hidden slide fastener (curves in a concave shape) A large wavy wrinkle may occur in the tape extending part).

For this reason, for example, when the tape extension part is greatly raised, the fastener tape cannot be accurately pressed by the sewing machine foot of the sewing machine, and when a wavy large wrinkle occurs in the tape extension part, for example, Since the fastener tapes partially overlap each other, it becomes difficult to perform sewing with the sewing machine with the left and right fastener tapes in the hidden slide fastener.

In addition, if the zipper tape has a large lift, sink, or wavy wrinkle even after sewing, there is a problem that the appearance (appearance quality) of the fastener-attached product is reduced. Furthermore, when the above-described large lift, sink, or wavy wrinkle has occurred on the fastener tape in the hidden slide fastener after sewing, the fastener is removed when the slider is slid along the element row. When the tape slides with the slider, the sliding resistance of the slider is increased, and the sliding property of the slider is sometimes lowered.

The present invention has been made in view of the above-described conventional problems. A specific object of the present invention is to provide a fastener tape when a slide fastener is bent in the tape width direction of the fastener tape and sewn to a fastener-attached product. Fastener stringer that can be held stably in a substantially flat shape, and can be prevented from causing partial lifting or sinking or wavy wrinkles in the fastener tape after sewing. And a slide fastener having the same fastener stringer.

In order to achieve the above object, a fastener stringer for a slide fastener provided by the present invention basically includes a fastener tape, and a continuous fastener element attached to one side edge of the fastener tape. The fastener element has a meshing head, an upper and a lower leg extending from the meshing head in the tape width direction, and a connecting part for connecting adjacent fastener elements to each other, and the fastener The other side edge of the tape is a fastener stringer for a slide fastener extending beyond the end of the fastener element on the side of the connecting part, and the end of the end of the fastener element on the side of the connecting part of the fastener tape. Extension length in the tape width direction from the position to the tape edge on the other side of the fastener tape Are those most important characterized by being regulated smaller than 12 mm.
In particular, in the present invention, it is preferable that the extension length is regulated to 10 mm or less, and further to 6 mm or less.

In the fastener stringer according to the present invention, the fastener tape is made of a woven fabric, and has a tape main part and an element attachment part arranged on one side edge side of the tape main part, and the other side of the tape main part. It is preferable that an edge is arranged on the edge, and the warp arranged on the ear has a higher tension than the warp arranged on the tape main body other than the ear.
In this case, it is particularly preferable that 4 or more and 6 or less warps are arranged in the ear portion.

In the fastener stringer of the present invention, the fastener tape includes a tape main portion, a tape bent portion that extends from one side edge of the tape main portion in the tape width direction and is bent in a U shape, And an element attaching portion to which the fastener element is attached. The fastener element is connected to the element attaching portion of the fastener tape, and the meshing head is attached to the tape bending portion. It is suitably provided as a fastener stringer that protrudes outward from the part.

In particular, the fastener stringer of the present invention is more suitably provided as a fastener stringer in which the fastener element is woven into the element attachment portion at the same time that the fastener tape is woven.

On the other hand, the fastener stringer of the present invention has the fastener tape having a tape main part and an element attaching part that extends from one side edge of the tape main part in the tape width direction and to which the fastener element is attached. The fastener element is also preferably used as a fastener stringer attached to the element attachment portion of the fastener tape with the meshing head protruding outward from the tape side edge on the element attachment portion side. Provided.

Further, according to the present invention, a slide fastener having a fastener stringer having the above-described configuration is provided.

The fastener stringer fastener tape according to the present invention has, on the other side edge portion of the fastener tape, a tape extending portion that extends beyond the edge of the connecting portion side of the fastener element. The extension length in the tape width direction from the position of the edge of the fastener element on the connecting portion side to the tape edge on the other side of the fastener tape (that is, the tape width direction dimension in the tape extension portion) is from 12 mm Is preferably set to 10 mm or less, particularly preferably 6 mm or less.

Thus, when the extension length of the fastener tape is regulated to be smaller than 12 mm, when the fastener stringer is bent in the tape width direction of the fastener tape, the tape extension portion of the fastener tape is partially It is possible to effectively reduce the size of rising and sinking and the size of the wavy ridge.

In particular, as a result of repeating various experiments and studies while the inventor changed the extension length of the fastener tape, it is preferable that the extension length is restricted to 10 mm or less and further to 6 mm or less. It was revealed. That is, if the extension length (the dimension in the tape width direction in the tape extension portion) is 10 mm or less, the size of the rising or sinking in the tape extension portion and the size of the wavy wrinkles are further reduced. Can be made inconspicuous.

Furthermore, if the extension length is 6 mm or less, the tape extension portion of the fastener tape is held substantially flat even when the bending (curvature) is increased and the fastener stringer is bent in the tape width direction. Can do. Therefore, even when the fastener stringer is bent in the tape width direction of the fastener tape and sewed on the fastener-attached product, the fastener can be sewn while holding the tape extending portion of the fastener tape substantially flat. Stringer can be sewn stably. Further, in this case, since the tape extending portion of the fastener tape becomes extremely thin in the tape width direction, the effect of reducing the manufacturing cost of the slide fastener and reducing the weight of the slide fastener can be obtained.

Further, in the fastener stringer of the present invention, it is possible to prevent partial lifting, sinking, or wavy wrinkles on the fastener tape after being sewn to the fastener-attached product, or partial lifting. Even if subsidence or wavy wrinkles occur, it can be made inconspicuously small, so that it is possible to prevent the appearance quality of the fastener-attached product to which the fastener stringer is sewn from being deteriorated.

Furthermore, in a slide fastener constructed using the same fastener stringer, the slider and the fastener tape are difficult to slide when the slider slides, so that excellent sliding performance of the slider can be secured stably.

In such a fastener stringer of the present invention, the fastener tape is made of a woven fabric, and has a tape main portion and an element mounting portion arranged on one side edge side of the tape main portion. Further, an ear portion is disposed on the other side edge portion of the tape main portion, and the warp disposed on the ear portion has a higher tension than the warp disposed on other than the ear portion of the tape main portion.

This makes it possible to stably hold the form of the fastener tape in which the width dimension of the tape extension is restricted. For this reason, when the fastener stringer is bent, the tape extension can be prevented from rising or sinking, and wavy wrinkles can be prevented more reliably, and the fastener stringer can be further sewn. It becomes easy. In addition, since the warp arranged in the ear portion has a high tension, the woven tissue inside the ear portion in the tape main portion can be stabilized, and further, the selection of the woven tissue employed in the fastener tape can be made. The width is expanded.

In this case, 4 or more and 6 or less warps are arranged on the ear portion of the fastener tape. By having four or more warps arranged in the ear part, the form of the fastener tape can be more stably maintained. In particular, even when the tension of the weft is strong, the weft can be stably folded at the ear portion, and the form of the fastener tape is stably maintained. On the other hand, the number of warp yarns arranged in the ear portion is 6 or less, so that the tension on the ear portion side of the fastener tape is prevented from becoming too strong, and the ear portion side of the fastener tape is greatly contracted, so-called bias is applied to the fastener tape. Can be prevented.

According to the present invention, the fastener tape includes a tape main part, a tape bent part that extends in a tape width direction from one side edge of the tape main part, and is further bent from the tape bent part. The fastener element is attached to the element attachment portion of the fastener tape so that the meshing head protrudes outward from the tape bending portion. The present invention is effectively applied to a so-called hidden string fastener fastener stringer.
In this case, the fastener stringer of the present invention can constitute a fastener stringer in which the fastener element is woven into the element attachment portion at the same time that the fastener tape is woven.

Further, in the present invention, the fastener tape has a tape main part, and an element attachment part that extends from one side edge of the tape main part in the tape width direction and to which the fastener element is attached. Also effective for so-called normal type fastener stringers in which the fastener element is attached to the element attachment part of the fastener tape with the engaging head protruding outward from the tape side edge on the element attachment part side Applies to

If it is such a fastener fastener stringer for slide fasteners or a normal type fastener stringer according to the present invention, even if it is curved in the tape width direction of the fastener tape, it partially lifts or sinks in the tape extension portion of the fastener tape. In addition, it is possible to eliminate the generation of wavy wrinkles, or to make the wavy wrinkles small enough to be inconspicuous even if wavy wrinkles are generated.

And the slide fastener of this invention which has a fastener stringer provided with the above-mentioned structure is smaller than 12 mm in the tape width direction of the tape extension part in a fastener tape, Preferably it is 10 mm or less, Most preferably, it is 6 mm or less. Is set to Therefore, when the slide fastener of the present invention is sewn to the fastener-attached product in a state where the slide fastener is curved in the tape width direction, the fastener stringer can be stably sewn.

In addition, slide fasteners sewn on fastener-attached products should not cause partial lifting or sinking, or wavy wrinkles on the fastener tape, or partially lifting or sinking, or Even if wavy wrinkles occur, the size can be made inconspicuous, so that the appearance quality of the fastener-attached product can be prevented from deteriorating. In this case, since the slider and the fastener tape are less likely to slide when the slider slides, excellent sliding performance of the slider can be secured stably.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The present invention is not limited to the examples described below, and various modifications can be made as long as it has substantially the same configuration as the present invention and has the same effects. Is possible.

For example, the continuous fastener element described in the following embodiments is formed by forming a monofilament into a coil shape, but the present invention is not limited to this, and the continuous fastener element zigzags the monofilament. It may be formed by molding into a shape.

FIG. 1 is a rear view showing the rear side of the hidden slide fastener according to the first embodiment, and FIG. 2 is a cross-sectional view schematically showing the section of the hidden slide fastener. 3 is a copy of a photograph of the back side of the hidden slide fastener, and FIG. 4 is a copy of a photograph of the front side of the hidden slide fastener.

Note that FIG. 2 schematically shows a cross section of the hidden slide fastener in which the left and right fastener elements are engaged with each other in order to easily understand the state of the warp yarn of the fastener tape. Although the tape bent portions of the left and right fastener tapes are shown separated from each other even if they are meshed, when the left and right fastener elements are meshed with an actual hidden slide fastener, as described later The tape bent portions of the left and right fastener tapes can be in close contact with each other so that the fastener elements can be hidden from view from the outer surface side.

In the following description, the front-rear direction refers to the length direction of the fastener tape, and is the same direction as the sliding direction in which the slider slides. Further, the left-right direction refers to the tape width direction in the tape main portion of the fastener tape, and refers to the direction parallel to the tape surface of the tape main portion and orthogonal to the tape length direction.

Furthermore, the vertical direction refers to the tape front and back direction perpendicular to the tape surface of the fastener tape. In particular, the direction on the side where the fastener element is attached to the fastener tape is the upper side, and the opposite direction is the lower side. It prescribes. In this case, the lower surface side of the hidden slide fastener is the front side exposed to the outside in the hidden slide fastener.

The hidden slide fastener 10 according to the first embodiment is used by being attached to a fastener-attached product such as a seat cover of an automobile seat, for example. The hidden slide fastener 10 includes a pair of left and right fastener stringers 20 formed with element rows 22, an upper stopper 11 fixed to the front end side of the element row 22 of each fastener stringer 20, and an element row of each fastener stringer 20. 22 has a lower stopper 12 fixed to the rear end side of the slider 22 and a slider 13 for a hidden slide fastener attached to be slidable along the element row 22.

In the hidden slide fastener 10, the slider 13 is slid toward the upper stopper 11 to engage the left and right element rows 22 to close the hidden slide fastener 10, and the slider 13 is moved to the lower stopper 12. By sliding toward the side, the left and right element rows 22 are separated and the hidden slide fastener 10 is opened. Note that the upper stopper 11, the lower stopper 12, and the slider 13 for the hidden slide fastener in the hidden slide fastener 10 are configured in the same manner as conventionally used.

In the first embodiment, each of the left and right fastener stringers 20 includes a woven fastener tape 21 and a coil-like fastener element 23 attached to the fastener tape 21, and a fastener element continuous in a coil shape. 23 is woven into the fastener tape 21, whereby an element row 22 is formed.

The fastener tape 21 includes an element attachment portion 21a in which the fastener element 23 is woven, a tape bent portion 21b that extends from one side edge of the element attachment portion 21a in the tape width direction and is bent in a U shape, and a tape. It further has a tape main portion 21c that extends from the bent portion 21b and becomes a portion that is sewn to the fastener-attached product.

The fastener element 23 is formed by molding a monofilament made of a thermoplastic resin such as polyamide or polyester into a coil shape, and is formed so as to extend in the tape width direction from the meshing head 23a and the meshing head 23a. Upper and lower leg portions 23b, 23c, and a connecting portion 23d for connecting the extended end portion of the upper leg portion 23b or the lower leg portion 23c to the lower leg portion 23c or the upper leg portion 23b of the fastener element 23 adjacent to the front and rear. The fastener element 23 is attached to the element attachment portion 21a of the fastener tape 21 so that the meshing head portion 23a protrudes outward from the tape bent portion 21b of the fastener tape 21.

The fastener tape 21 according to the first embodiment is woven by reciprocating the carrier bar into the warp opening and inserting the weft yarn 24a. As shown in FIG. The tape bent portion 21b is a woven fabric woven by ground weft yarns 24a composed of double yarns and a plurality of ground warp yarns 24b. Further, a tape end edge of the tape main body portion 21c opposite to the side where the tape bent portion 21b is formed is inserted with a knitting needle (not shown), and the next weft yarn 24a is sequentially hooked so that the loop folded end is formed. It is formed by connecting.

The element attachment portion 21a of the fastener tape 21 passes through the upper fixing warp 24c running in the warp direction on the upper leg portion 23b of each fastener element 23 and the lower surface side of the lower leg portion 23c of each fastener element 23. The position of the lower fixing warp 24d that travels in the direction, the tightening warp 24e that travels in the warp direction so as to cross between the upper and lower legs 23b and 23c, and the position in the weft direction of the upper and lower fixing warps 24c and 24d The positioning warp yarn 24f and the ground weft yarn 24a that is also inserted into the tape main portion 21c and the tape bent portion 21b are arranged. Since the element attachment portion 21a is configured using these

warps

24c, 24d, 24e, 24f and the ground weft 24a, the fastener element 23 is firmly woven into the element attachment portion 21a so that the fastener element 23 is attached. Can be stabilized.

Further, in the fastener tape 21, the various warp yarns 24b to 24f arranged in the element attaching portion 21a, the tape bent portion 21b, and the tape main portion 21c are processed with polyester having a thickness of 160 dtex or more and 550 dtex or less. Yarn is used, and polyester processed yarn having a thickness of 550 dtex or more and 1100 dtex or less is used for the single weft yarn 24a.

In particular, in the case of the first embodiment, the various warp yarns 24b to 24f arranged in the element attaching portion 21a, the tape bent portion 21b, and the tape main portion 21c have a thickness of 330 dtex, and the weft yarn 24a The single yarn has a thickness of 700 dtex. In the present invention, the thickness and material of the weft and various warps are not particularly limited, and can be appropriately changed according to the size of the fastener element, the use of the hidden slide fastener, and the like.

In such a hidden slide fastener 10 according to the first embodiment, the tape main portion 21c of the fastener tape 21 has a tape extending portion 25 that extends beyond the end edge of the fastener element 23 on the connecting portion 23d side. Yes. That is, in the hidden slide fastener 10 according to the first embodiment, when the position of the end edge of the fastener element 23 on the connecting portion 23d side is set as the reference position in the left-right direction of the hidden slide fastener 10, the fastener tape 21 is moved from the reference position. The tape width dimension of the tape main part 21c is set so that the extension length X to the tape edge on the tape main part 21c side satisfies X> 0 mm. In this case, when the hidden slide fastener 10 is viewed from the fastener element 23 side, the tape extending portion 25 is exposed to the outside of the connecting portion 23 d of the fastener element 23.

Thus, by setting the extension length X from the reference position to the tape edge to X> 0 mm, the tape extension portions 25 can be reliably provided on the left and right fastener tapes 21. As a result, when weaving the fastener tape 21 while weaving the fastener element 23 using a loom as will be described later, the tape extending portion 25 of the woven fastener tape 21 is not shown in the figure on the downstream side of the loom. The fastener tape 21 can be smoothly woven while being pulled (carrying) by being sandwiched between rollers. For this reason, the fastener tape 21 having a desired woven structure can be woven stably with high accuracy without causing the fastener tape 21 to bend or bend.

Furthermore, in Example 1, the dimension in the tape width direction of the tape extending portion 25 of the fastener tape 21 is regulated to 6 mm or less. That is, the dimension in the tape width direction of the tape main body 21c is set so that the extension length X from the reference position to the tape edge on the tape main body 21c side of the fastener tape 21 satisfies 0 mm <X ≦ 6 mm. ing.

At this time, when the thickness of the ground warp yarn 24b arranged in the tape main body portion 21c is set to 330 dtex as described above, and the tape extending portion 25 has a width dimension of 3 mm, for example, Approximately 20 ground warp yarns 24b are disposed in the tape extending portion 25 (FIG. 2 is disposed in the tape extending portion 25 for easy understanding of the features of the hidden slide fastener 10 of the first embodiment. The cross section is shown with a smaller number of ground warp yarns 24b). In the first embodiment, by reducing the number of warp yarns arranged on the tape main portion 21c of the fastener tape 21 (particularly, the number of warp yarns arranged on the tape main portion 21c other than the ear portion 26 described later), The dimension of the tape extending direction 25 of the fastener tape 21 in the tape width direction is regulated.

As described above, when the extension length X (the dimension in the tape width direction) of the tape extension portion 25 is 6 mm or less, the hidden slide fastener 10 (fastener stringer 20) is attached to the fastener tape as shown in FIG. 5, for example. When the tape extending portion 25 is bent in the tape width direction, the tape extending portion 25 is partially lifted or submerged, and the tape extending portion 25 is effectively suppressed from wavy wrinkles. The tape extending portion 25 can be held flat.

In this case, the shorter the extension length X is, the easier it is to keep the tape extension 25 flat even when the fastener stringer 20 is curved in the tape width direction. When the dimension in the tape width direction of the tape extending portion 25 is shortened, it is difficult to sew the fastener stringer 20 when the tape main body portion 21c of the fastener stringer 20 is sewn to the fastener-attached product.

That is, in the hidden slide fastener 10 of the first embodiment, for example, when the extension length X of the fastener tape 21 from the reference position to the tape edge is 0 mm <X ≦ 2 mm, the extension length X Compared to when 4 mm <X ≦ 6 mm, even if the fastener stringer 20 is greatly curved in the tape width direction, the tape extension portion 25 is partially lifted, and the tape extension is more effectively suppressed. The portion 25 can be stably held flat.

On the other hand, for example, when the extension length X from the reference position to the tape edge of the fastener tape 21 is 4 mm <X ≦ 6 mm, compared to the case where the extension length X is 0 mm <X ≦ 2 mm. Thus, for example, when the fastener stringer 20 is sewn to the fastener-attached product using a sewing machine, the tape main portion 21c of the fastener tape 21 can be more stably pressed by the sewing machine foot of the sewing machine. Sewing can be performed more smoothly.

Further, when the extension length X of the fastener tape 21 from the reference position to the tape edge is, for example, 2 mm <X ≦ 4 mm, the tape extension when the fastener stringer 20 is greatly curved in the tape width direction. The protruding portion 25 can be held flat, and the fastener stringer 20 can be smoothly sewed when the fastener stringer 20 is sewn to the fastener-attached product. In the first embodiment, the extension length X of the fastener tape 21 can be arbitrarily selected within the range of 0 mm <X ≦ 6 mm depending on the application of the hidden slide fastener 10 and the like. .

Further, in the hidden slide fastener 10 of the first embodiment, the tape main body portion 21c of the fastener tape 21 has an ear portion 26 disposed on the tape side edge opposite to the tape bent portion 21b side. The ground warp yarn 24b disposed in the ear portion 26 has a higher tension than the ground warp yarn 24b disposed other than the ear portion 26 of the tape main body portion 21c. Since the ground warp yarn 24b arranged in the ear part 26 has a high tension in this way, the ground arranged in the ear part 26 as shown in FIG. 3 and FIG. The warp yarn 24b is stretched and stretched more strongly than the ground warp yarn 24b disposed on the inside thereof.

In this case, it is preferable that the number of the ground warp yarns 24b arranged in the ear portion 26 is set to 4 or more and 6 or less. In the ear portion 26 in the first embodiment, the six warp yarns have a high tension. Is arranged. Since the ear portion 26 of the fastener tape 21 is provided with four or more high-tensile warps, for example, when the tension applied to the ground weft 24a is high (strong) or when the fastener tape 21 is moved in the tape width direction. Even when it is bent, the edge of the fastener tape 21 on the ear portion 26 side can be prevented from being twisted or bent, and the form of the fastener tape 21 can be stably held.

Further, since four or more high-tensile warp yarns are arranged on the ear portion 26, the woven structure of the fastener tape 21 inside the ear portion 26 can be stabilized. For example, the hidden slide fastener 10 can be washed and the like. Even if it is applied, the position of the weave can be prevented from shifting. Furthermore, the freedom degree of selection of the woven structure employ | adopted as the fastener tape 21 can also be expanded greatly.

On the other hand, since the number of high-tension warps arranged on the ear portion 26 of the fastener tape 21 is six or less, the tension in the tape length direction of the ear portion 26 of the fastener tape 21 can be prevented from becoming too strong. Thus, the so-called bias form is generated in the fastener stringer 20 in which the tape side edge portion on the ear portion 26 side of the fastener tape 21 is greatly contracted and the entire fastener tape 21 is curved so that the tape side edge portion is concave. Can be prevented.

Next, a method for manufacturing the hidden slide fastener 10 according to the first embodiment will be described.
First, the fastener stringer 20 is manufactured. Specifically, by using a loom to reciprocate the carrier bar into the openings of the warp yarns arranged in a predetermined number and insert the wefts, a fastener tape 21 having a predetermined dimension in the tape width direction is obtained. Weaving with a woven tissue. In this case, the tension of the warp yarn is adjusted so that the tension of the ground warp yarn 24 b arranged on the ear portion 26 of the fastener tape 21 is increased, and the fastener tape 21 is woven.

Further, at the same time that the fastener tape 21 is woven in this way, the coil-shaped fastener element 23 formed from the monofilament is arranged with the meshing head portion 23a facing the inside of the fastener tape 21. Weaving into the mounting portion 21a.

Subsequently, after the fastener tape 21 is woven, the tape portion that becomes the tape bending portion 21b of the fastener tape 21 is folded back into a U shape, and the meshing head portion 23a of the fastener element 23 is folded into the U shape. It protrudes outward from the part 21b. Furthermore, a heat setting process is performed on the fastener tape 21 in such a bent form. Thereby, the fastener stringer 20 for the hidden slide fastener in which the meshing head 23a protrudes outward from the tape bent portion 21b is obtained.

Further, the obtained fastener stringers 20 are combined in pairs, and the slider 13 is slidably attached to the element rows 22 of these fastener stringers 20, whereby the hidden slide fastener 10 of the first embodiment is manufactured. The When the left and right fastener elements 23 are engaged with each other, the hidden slide fastener 10 can bring the tape bent portions 21b of the left and right fastener tapes 21 into close contact with each other. When viewed from the side exposed to the left and right, the left and right fastener elements 23 in the meshed state can be hidden by the fastener tape 21 (particularly, the tape bent portion 21b and the tape main portion 21c).

And the hidden slide fastener 10 of the present Example 1 manufactured as mentioned above has the extension length X (the dimension of the tape width direction) in the tape extension part 25 of the fastener tape 21 of 6 mm or less, and the conventional hidden fastener. Compared with the slide fastener 10, it is set to be extremely small. Therefore, the manufacturing cost of the hidden slide fastener 10 can be reduced and the weight can be reduced. Even when the hidden slide fastener 10 is bent in the tape width direction of the fastener tape 21 as shown in FIG. The tape main portion 21c of the fastener tape 21 is substantially suppressed by effectively suppressing the tape extension portion 25 of the tape from partially rising or sinking and the occurrence of wavy wrinkles in the tape extension portion 25. It can be held flat.

Therefore, when the hidden slide fastener 10 of the first embodiment is bent in the tape width direction of the fastener tape 21 and is sewn to a fastener-attached product such as an automobile seat cover, the tape main portion 21c of the fastener tape 21 is used. (Especially, the position of the tape main portion 21c on the tape bent portion 21b side) and the fastener-attached product are sewn together, the undulation in the tape front and back direction generated in the fastener tape 21 is reduced or the occurrence of undulation in the tape front and back direction is generated. Thus, the hidden slide fastener 10 (or the fastener stringer 20) can be sewn stably while the tape main portion 21c of the fastener tape 21 is held substantially flat.

Further, the hidden slide fastener 10 of the first embodiment is partially lifted and submerged in the fastener tape 21 even after being sewn to the fastener-attached product in a state of being bent in the tape width direction of the fastener tape 21. Or the wavy wrinkle is not generated, or even if the wavy wrinkle occurs, the hidden slide fastener 10 can be sewn. It is possible to prevent the appearance quality of the worn fastener-attached product from being deteriorated.

Further, when the slider 13 is slid to open and close the hidden slide fastener 10, the fastener tape 21 of the hidden slide fastener 10 is not partially raised or sinked, or wavy wrinkles are not generated or small. The sliding resistance of the slider 13 can be prevented from deteriorating due to the sliding of the slider 13 and the fastener tape 21 without increasing the sliding resistance of the slider 13.

Further, in the hidden slide fastener 10 of the first embodiment, four or more and six or less warps having high tension as described above are arranged on the tape side edge of the fastener tape 21 on the tape main body 21c side. The ear | edge part 26 is formed by. Thereby, the form (especially form of the tape main-body part 21c) of the fastener tape 21 can be hold | maintained stably. Accordingly, when the hidden slide fastener 10 is bent in the tape width direction and is sewn to the fastener-attached product, the tape extending portion 25 of the fastener tape 21 can be more securely held in a substantially flat shape, and the hidden slide fastener 10 can be sewn. Can be performed more stably and cleanly.

FIG. 6 is a cross-sectional view of the hidden slide fastener according to the second embodiment.

The tape width direction dimension of the tape main portion 41c is set so that the extension length X to the tape edge on the tape main portion 41c side satisfies X> 0 mm.

Thus, the tape extending portions 45 can be provided on the left and right fastener tapes 41 by setting the extending length X from the reference position to the tape edge to X> 0 mm. Thus, for example, when the hidden slide fastener 30 is manufactured, when the fastener tape 41 is conveyed in the state of a fastener chain in order to perform a heat setting process or a dyeing process, the tape extending portion 45 of the fastener tape 41 is moved by the upper and lower rollers. The fastener chain can be reliably pinched, and a predetermined treatment can be stably applied to the fastener chain without the fastener tape 41 being twisted or bent.

In the hidden slide fastener 30 of the second embodiment, the tape width dimension of the tape extending portion 45 of the fastener tape 41 is regulated to 6 mm or less. That is, the tape width direction dimension of the tape main portion 41c is set so that the extension length X from the reference position to the tape end edge on the tape main portion 41c side of the fastener tape 41 satisfies 0 mm <X ≦ 6 mm. ing.

Furthermore, in the hidden slide fastener 30 of the second embodiment, the tape main portion 41c of the fastener tape 41 has an ear portion 46 disposed on the tape side edge opposite to the tape bent portion 41b side. The warp yarn arranged in the ear portion 46 has higher tension than the warp yarn arranged other than the ear portion 46 of the tape main body portion 41c. In this case, six warps are arranged in the ear portion 46 with high tension. Thereby, the form of the fastener tape 41 can be stabilized without causing the fastener tape 41 to be biased.

In the hidden slide fastener 30 of the second embodiment having the above-described configuration, the extension length X in the tape extension portion 45 of the fastener tape 41 is regulated to 6 mm or less, and the tape main body in the fastener tape 41 is An ear portion 46 in which a warp having high tension is arranged is formed on the side edge of the tape on the side of the portion 41c. For this reason, the hidden slide fastener 30 of the second embodiment can obtain the same effect as that of the hidden slide fastener 30 according to the first embodiment.

FIG. 7 is a front view of the slide fastener according to the third embodiment, and FIG. 8 is a cross-sectional view of the slide fastener.
The normal type slide fastener 50 according to the third embodiment (hereinafter, the normal type slide fastener is simply referred to as “slide fastener”) includes a pair of left and right fastener stringers 60 on which element rows 62 are arranged, and each fastener stringer.
