Products with zippers, methods for manufacturing products with zippers, and woven zipper stringers

Abstract

Each woven fastener stringer (20, 20a, 20b, 20c) in a fastener-attached product (1, 2, 3) according to this invention has such a shape that an element attachment part (24) of a fastener tape (21, 21a, 21b) is folded back with respect to a main tape body (22) at a folded part (23). Warp threads (30) of the fastener tape (21, 21a, 21b) comprise a plurality of first warp threads (31) that have the same thickness as one another and second warp threads (32) that are thicker than the first warp threads (31). A sewing part (60) of a sewing thread pass through the fastener tape (21, 21a, 21b) at a position near the second warp threads (32) and sews the woven fastener stringer (20, 20a, 20b, 20c) and a fastener-attached member (6, 7, 8) each other. As a result, the positions of the warp threads (30) of the fastener tape (21, 21a, 21b) are unlikely displaced in a weft thread direction even when a strong lateral pulling force is applied, thereby being able to prevent or to suppress exposure of the fastener tape (21, 21a, 21b) and an element row to the outside.

Description

Technical Field

[0001] The present invention relates to a product with a fastener having a pair of woven fastener stringers and a fastener-attached member to which the woven fastener stringers are sewn by a sewing portion of a sewing thread, a method for manufacturing the product with a fastener, and a woven fastener stringer used for the product with a fastener.

Background Art

[0002] As one of slide fasteners, there is known a hidden-type slide fastener (hereinafter referred to as a hidden slide fastener) having a concealability such that when left and right element rows are meshed with each other, fastener elements are made invisible (or difficult to see) from the outer surface side of the slide fastener.

[0003] Japanese Patent Application Laid-Open No. 2008-119076 (Patent Document 1) describes a woven fastener stringer used for a hidden slide fastener, which includes a fastener tape having a woven structure and a plurality of fastener elements woven and fixed to a part of the fastener tape during the weaving of the fastener tape.

[0004] In the woven fastener stringer of Patent Document 1, in the element attachment portion of the fastener tape, as warp threads of the woven structure, an upper fixing warp thread that runs in the warp direction on the outer surface of the upper leg portion of each fastener element, a lower fixing warp thread that runs in the warp direction on the outer surface of the lower leg portion of each fastener element, and a tightening warp thread that runs in the warp direction so as to alternately straddle the upper leg portion and the lower leg portion of the fastener element are arranged. Further, in Patent Document 1, the total fineness of the lower fixing warp thread that runs on the meshing head portion side of the fastener element rather than the tightening warp thread is set to be larger than the total fineness of the upper fixing warp thread that runs on the meshing head portion side rather than the tightening warp thread.

[0005] According to the woven fastener stringer of Patent Document 1, the lower fixing warp threads, which run on the interlocking head side of the fastener elements, are more densely arranged than the tightening warp threads. Therefore, when a concealed slide fastener is manufactured using the woven fastener stringer of Patent Document 1, when the left and right rows of elements of the concealed slide fastener are interlocked, and a lateral pulling force is applied to pull the left and right fastener tapes from the left and right outer sides in the width direction, it is possible to make it difficult for a gap to form between the left and right fastener tapes. As a result, the concealability of the concealed slide fastener can be improved. [Prior art documents] [Patent Documents]

[0006] [Patent Document 1] Japanese Patent Publication No. 2008-119076 [Overview of the Initiative] [Problems that the invention aims to solve]

[0007] In conventional woven zipper stringers such as those described in Patent Document 1, the zipper tape is woven by inserting weft threads into multiple warp threads. Furthermore, during the weaving of the zipper tape, the zipper elements are inserted into the warp threads in accordance with the timing of the weft thread insertion, thereby weaving and fixing the zipper elements into a portion of the zipper tape.

[0008] However, in a woven zipper stringer formed by corresponding the insertion of weft threads into the zipper tape with the insertion of zipper elements, the density of weft threads in the longitudinal direction of the zipper tape becomes smaller compared to, for example, a zipper tape with a general woven structure in which the zipper elements are not woven.

[0009] When a concealed slide fastener is formed using a woven fastener stringer with a low weft density, the following problems may occur when the concealed slide fastener is sewn onto a fastener-attached material such as fabric to manufacture a product with the concealed slide fastener.

[0010] In other words, in a manufactured product with a concealed slide fastener, when the fastener attachment material (fabric) is strongly pulled, the concealed slide fastener is subjected to a large lateral pulling force through the seam connecting the fastener attachment material and the woven fastener stringer. At this time, because the density of the weft threads in the fastener tape is small as described above, the position of the warp threads, which are located close to the seam of the fastener tape, is easily shifted in the weft direction by the aforementioned lateral pulling force.

[0011] As a result, the misalignment of the warp threads can easily cause the position of the sewing area to shift in the weft direction, which in turn can cause the position of the zipper attachment members to shift, potentially creating a gap between the left and right zipper attachment members. Furthermore, if the position of the warp threads near the sewing area of ​​the zipper tape shifts in the weft direction, a gap is more likely to form between the left and right zipper tapes, or the gap between the left and right zipper tapes is more likely to widen. Therefore, there was a risk that the zipper tape or element row of a concealed slide zipper could be exposed to the outside through the gap formed between the left and right zipper attachment members.

[0012] The present invention has been made in view of the above problems, and its object is to provide a product with a zipper that can prevent or suppress the exposure of the zipper tape and element row to the outside by making it difficult for the warp threads of the zipper tape to shift in the weft direction even when subjected to a strong lateral pulling force, a method for manufacturing such a product with a zipper, and a woven zipper stringer used in such a product with a zipper.

[0026] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings and examples. It should be noted that the present invention is not limited to the embodiments described below, and various modifications are possible as long as they have substantially the same configuration as the present invention and produce similar effects.

[0027] For example, in each of the following embodiments, we will describe a case where the zippered product is a zippered seat cover that is attached to the seat of a car. However, the zippered product of the present invention is not limited to car seat covers, and the present invention can be applied to a variety of other products such as clothing, bags and other everyday goods. [Examples]

[0028] Figure 1 is a schematic bottom view of the concealed slide fastener of this embodiment 1, and Figure 2 is a cross-sectional view taken along the line II-II shown in Figure 1. Figure 3 is a schematic cross-sectional view showing the main part of a seat cover manufactured by sewing the concealed slide fastener to the surface material in this embodiment 1. In Figures 2 and 3, the weave structure is shown coarsely to make it easier to understand the features of the invention, but in reality, considering the function as a woven fastener stringer, threads of the required thickness are used for the various weft and warp threads, and the weave structure is also formed densely.

[0029] Furthermore, in the following explanation, the front-to-back direction refers to the direction along the length of the concealed slide fastener or woven fastener stringer, or the direction along the sliding direction of the slider in the concealed slide fastener, and is the same direction as the up-and-down direction on the page of Figure 1, for example. In this case, the direction in which the slider is slid to close the concealed slide fastener by engaging the left and right rows of elements is considered the front, and the direction in which the slider is slid to open the slide fastener by separating the left and right rows of elements is considered the rear.

[0030] The left-right direction is the direction along the width direction of the concealed slide fastener or the direction in which the left and right rows of elements in the concealed slide fastener interlock and separate, and is the same direction as the left-right direction on the paper in Figure 1, for example. Furthermore, the inside of the left-right direction means the direction in which the left and right woven fastener stringers are brought closer to each other, and the outside of the left-right direction means the direction in which the left and right woven fastener stringers are separated from each other.

[0031] The vertical direction is the direction along the thickness direction or front-to-back direction of the concealed slide fastener, for example, the same direction as the front-to-back direction of the paper in Figure 1. In this case, the direction in which the tape body of the fastener tape is positioned relative to the fastener element is considered upward, and the direction on the opposite side is considered downward. Regarding the weave structure of the zipper tape, the weft direction (or weft direction) refers to the direction along the weft threads when viewing the weave structure of the zipper tape, or the direction along which the weft threads are inserted into multiple warp threads during the weaving of the zipper tape. Furthermore, the warp direction (or warp direction) of the weave structure refers to the direction perpendicular to the weft direction on the zipper tape in the weave structure of the zipper tape.

[0032] The concealed slide fastener 10 of this embodiment 1 is used by being attached to the surface material (fabric) 6 of an automobile seat cover 1, for example, as shown in Figure 3. In this case, the fastener product according to this embodiment is a seat cover 1 with a fastener, and the concealed slide fastener 10 is attached to the opening or closing part of the surface material 6 that forms the seat cover 1. In this case, the surface material 6 that forms the seat cover 1 is fabric or cloth, and the concealed slide fastener 10 is attached to the fastener-attached member by the sewing part 60 of the sewing thread. In this invention, the size, shape, material, etc. of the seat cover to which the concealed slide fastener is attached are not particularly limited.

[0033] The concealed slide fastener 10 of this embodiment 1 comprises a pair of left and right concealed type woven fastener stringers 20, a first fastener 11 and a second fastener 12 positioned at the front and rear ends of the left and right woven fastener stringers 20, and a slider 13 slidably attached to the element rows 50 of the left and right woven fastener stringers 20.

[0034] In this embodiment 1, the first fastener 11, the second fastener 12, and the slider 13 are formed substantially the same as the first fastener, second fastener, and slider used in conventional concealed slide fasteners. Furthermore, in the present invention, the first and second fasteners are not particularly limited and only need to be formed adjacent to the front and rear ends of the element row so that the slider does not fall off the element row. In addition, the concealed slide fastener of the present invention may be formed with a release insert that separates and allows the left and right woven fastener stringers to be separated instead of the second fastener, or it may be formed without the first and / or second fasteners.

[0035] The slider 13 comprises a slider body 14 and a pull handle (not shown) attached to the slider body 14. The slider body 14, although its specific structure is not shown, comprises a lower wing plate 14a, inverted L-shaped left and right flange portions rising from the left and right side edges of the lower wing plate 14a, a central column portion rising from the left-right center of the lower wing plate 14a, a guide portion extending or bulging from the upper end of the central column portion toward the left and right flange portions, and a pull handle attachment portion provided at the upper end of the central column portion to which the pull handle is attached.

[0036] Each of the left and right flange portions is formed in an inverted L shape by having a side wall portion extending upward from the side edge of the lower wing plate 14a and an upper wall portion extending inward in the left-right direction from the upper end of the side wall portion. The front end of the slider fuselage 14 is provided with shoulders formed on both the left and right sides of the central column, and the rear end of the slider fuselage 14 is provided with a rear opening. The slider fuselage 14 is also provided with a roughly Y-shaped element guide passage that communicates with the left and right shoulders and the rear opening.

[0037] In this invention, the slider is not particularly limited as long as it is formed to be able to engage and disengage the left and right element rows 50 by sliding along the left and right element rows 50. In addition, the concealed slide fastener 10 of this embodiment 1 may be formed to engage and disengage the element rows 50 using a dedicated opening and closing member (also called a jig) that is formed to be attachable to and detachable from the left and right element rows 50, instead of attaching the slider 13 as described above to the left and right element rows 50.

[0038] Each of the left and right woven zipper stringers 20 has a zipper tape 21 with a woven structure formed by multiple warp threads 30 and weft threads 35, and multiple zipper elements 51 that are woven into and fixed to a part of the zipper tape 21. As shown in Figure 3, each of the left and right woven zipper stringers 20 is attached to the surface member 6 of the seat cover 1 by a sewing portion 60 formed by sewing thread of a sewing machine through a sewing process described later. In Figure 3, the sewing portion 60 of the sewing thread is shown by a dashed line to make the woven structure of the zipper tape 21 easier to understand.

[0039] The fastener tape 21, when viewed in cross-section perpendicular to the front-to-back direction of the woven fastener stringer 20, has a tape body portion 22 that forms the outer surface (top surface) of the concealed slide fastener 10, a tape bent portion 23 that extends from the tape body portion 22 and is bent in a roughly U-shape or C-shape, and an element attachment portion 24 that extends from the tape bent portion 23 toward the back side of the tape body portion 22 and to which the fastener element 51 is fixed. As a result, the fastener tape 21 has a shape in which the tape body portion 22 and the element attachment portion 24 are superimposed in the vertical direction, as the element attachment portion 24 is folded back toward the back side of the tape body portion 22 by the tape bent portion 23.

[0040] Multiple fastener elements 51 are formed in a continuous shape, connected to one another without separating, by forming monofilaments of synthetic resin such as polyamide or polyester into a coil shape. Each fastener element 51 has a meshing head 52, upper legs 53 and lower legs 54 extending outward in the left-right direction from the upper and lower ends of the meshing head 52, and a connecting portion 55 that connects adjacent fastener elements 51 in the front-rear direction. In this case, the upper legs 53 of the fastener element 51 are positioned closer to the tape body portion 22 of the fastener tape 21 than the lower legs 54.

[0041] Multiple fastener elements 51 are attached to the fastener tape 21 when weaving the fastener tape 21, by inserting the upper legs 53 and lower legs 54 into the element attachment portion 24 of the fastener tape 21 and weaving them in with the interlocking heads 52 of the fastener elements 51 facing inward on the fastener tape 21. By attaching multiple fastener elements 51 to the fastener tape 21 in this way, an element row 50 is formed.

[0042] In the woven fastener stringer 20 of this embodiment 1, the weave structure of the fastener tape 21 is formed by a plurality of warp threads 30 and weft threads 35, as schematically shown in Figure 2. In this embodiment 1, the tape body portion 22 and the tape bend portion 23 of the fastener tape 21 are formed in a plain weave structure. In this case, the boundary portion 25 between the tape body portion 22 and the tape bend portion 23 refers to the position where the tape bend portion 23 begins to bend relative to the tape body portion 22, or a position near thereto, for example, in this embodiment 1, it is the position shown by the dashed line in Figure 2. In the present invention, the weave structure forming the tape body portion 22 and the tape bend portion 23 is not particularly limited.

[0043] The element attachment portion 24 of this embodiment 1 is formed of a woven structure that fixes the upper leg portion 53 and the lower leg portion 54 of the fastener element 51. Specifically, the woven structure of the element attachment portion 24 of this embodiment 1 is formed using a plurality of upper fixing warp threads 41 arranged along the warp direction on the upper surface side of the upper leg portion 53 of each fastener element 51, a plurality of lower fixing warp threads 42 arranged along the warp direction on the lower surface side of the lower leg portion 54 of each fastener element 51, a plurality of tightening warp threads 43 arranged along the warp direction while alternately pressing down the upper leg portion 53 and the lower leg portion 54 of the plurality of fastener elements 51, a plurality of positioning warp threads 44 that regulate the weft direction position of the upper fixing warp threads 41 and the lower fixing warp threads 42, and weft threads 35 that are continuously arranged along the weft direction from the tape bending portion 23.

[0044] In this embodiment 1, the element attachment portion 24 is formed when the fastener tape 21 is woven, with one fastener element 51 being inserted weft twice into the multiple warp threads 30 described above. Furthermore, the element attachment portion 24 is formed by multiple upper fixing warp threads 41, multiple lower fixing warp threads 42, and multiple tightening warp threads 43 holding the upper leg portion 53 and lower leg portion 54 of each fastener element 51, and by each warp thread 30 arranged in the element attachment portion 24 regularly intersecting the weft threads 35. As a result, multiple fastener elements 51 can be woven one by one into the element attachment portion 24 and fixed stably, and the position and pitch (distance between fastener elements 51) in the front-to-back direction of the fastener elements 51 can be stabilized.

[0045] In this case, the boundary portion 26 between the tape bend portion 23 and the element attachment portion 24 refers to the position between the upper fixing warp thread 41 of the multiple upper fixing warp threads 41 of the element attachment portion 24 that is positioned closest to the interlocking head 52, and the warp thread 30 that does not directly contribute to the fixing of the fastener element 51. In this invention, the element attachment portion of the fastener tape is not particularly limited in its weave structure, nor is it limited in the type and number of warp threads used in the element attachment portion, as long as it is formed so that the fastener element can be woven in and fixed.

[0046] In each woven fastener stringer 20 of this embodiment 1, the warp threads 30 forming the fastener tape 21 consist of a plurality of first warp threads 31 having the same thickness (fineness) and two second warp threads (also called regulating members) 32 that are thicker than the first warp threads 31. The two second warp threads 32 are each positioned close to the sewing portion 60 of the sewing thread.

[0047] More specifically, the second warp thread 32 is arranged in the side edge portion (side edge region) adjacent to the tape bend portion 23 of the tape body portion 22 and in the side edge portion (side edge region) adjacent to the tape bend portion 23 of the element attachment portion 24. In particular, in this embodiment 1, the second warp thread 32 is used in the warp thread 30 that is positioned closest to the tape bend portion 23 among the multiple warp threads 30 that form the tape body portion 22, and in one of the three upper fixing warp threads 41 that are positioned closer to the interlocking head 52 than the positioning warp thread 44 in the element attachment portion 24. In this invention, the position of the second warp thread is not particularly limited as long as it is close to the sewing portion. In this invention, proximity between the second warp thread and the sewing portion means a positional relationship in which the number of warp threads forming the fastener tape between the sewing portion and the second warp thread is 4 or less, preferably 2 or less, as will be described in more detail later.

[0048] The first warp threads 31 of the fastener tape 21 are made of polyamide or polyester multifilament yarn. Each first warp thread 31 has a fineness of 166 decitex or more and 500 decitex or less. For example, in this embodiment 1, all first warp threads 31 have a fineness of 330 decitex.

[0049] The second warp thread 32 of the fastener tape 21 is made of a flexible, cord-like material. In this case, the second warp thread 32 is formed with a larger cross-sectional area perpendicular to the length direction of the warp thread 30 than the first warp thread 31. Furthermore, the second warp thread 32 is formed with a cross-sectional area perpendicular to the length direction of the warp thread 30 that prevents or suppresses the displacement of the second warp thread 32 in the weft direction, even when the fastener tape 21 is subjected to a large force (lateral pulling force) from the sewing portion 60 of the sewing thread, for example, as described later, that causes the position of the first warp thread 31 to move in the weft direction. In other words, each second warp thread 32 is formed with a cross-sectional area perpendicular to the length direction of the warp thread 30 that makes it difficult for the position of the second warp thread 32 to shift in the weft direction compared to the first warp thread 31, even when subjected to the large lateral pulling force.

[0050] Furthermore, it is preferable that the second warp thread 32 be a cord-like member having a structure other than that of a multifilament yarn (i.e., a structure different from that formed by twisting together multiple single fibers). Specifically, it is preferable that the second warp thread 32 be a knitted cord, a braided cord, or a monofilament.

[0051] In particular, in this embodiment 1, the second warp thread 32 is preferably a knitted cord, which allows the second warp thread 32 to have appropriate flexibility and pliability, thereby enabling the stably woven zipper tape 21. Furthermore, even if the cross section perpendicular to the length direction of the second warp thread 32 is slightly flattened when the second warp thread 32 intersects with the weft thread 35, the area of ​​the cross section of the flattened part can be stably made larger than the cross section perpendicular to the length direction of the first warp thread 31.

[0052] Here, a knitted cord is a cord-like member formed by wrapping a core thread made of multifilaments in a woven section of knitted yarn. A braided cord is a cord-like member formed by crossing and combining bundles of fibers (for example, strands). Among braided cords, a diamond braid cord, which is made up of 12 strands, is preferably used as the second warp thread 32.

[0053] By using the aforementioned string-like member as the second warp thread 32, even if the zipper tape 21 is subjected to a large lateral pulling force from the sewing section 60, the position of the second warp thread 32 can be made less likely to shift in the weft direction more effectively.

[0054] Next, we will describe how to manufacture the woven fastener stringer 20 of this embodiment 1. First, the zipper tape 21 is woven using the multiple warp threads 30 and weft threads 35 described above. Simultaneously with weaving the zipper tape 21, the coiled zipper elements 51 are inserted into the element attachment portion 24 of the zipper tape 21 at the same time as the weft threads 35 are inserted into the warp threads 30, thereby weaving and fixing the zipper elements 51 one by one into the element attachment portion 24.

[0055] In this embodiment 1, as described above, the fastener element 51 is fixed to the element attachment portion 24 with the interlocking head 52 of the fastener element 51 facing inward on the fastener tape 21. Furthermore, the fastener elements 51 are woven into the element attachment portion 24 by inserting one fastener element 51 every two insertions of the weft thread 35 into the warp thread 30.

[0056] Next, the fastener tape 21, to which the fastener elements 51 are fixed to the element attachment portion 24, is bent into a roughly U-shape so that the element attachment portion 24 is folded back relative to the tape body portion 22 of the fastener tape 21. This bending of the fastener tape 21 forms a tape bend portion 23 on the fastener tape 21, and causes the interlocking head portion 52 of each fastener element 51 to protrude from the tape bend portion 23 of the fastener tape 21 to one side in the left-right direction (specifically, to the inside in the left-right direction when the concealed slide fastener 10 is formed).

[0057] Subsequently, the zipper tape 21 is subjected to a heat-setting treatment while it is folded. This heat-setting treatment maintains the folded shape of the zipper tape 21. This is how the woven zipper stringer 20 of this embodiment 1 is produced.

[0058] Furthermore, the obtained woven zipper stringers 20 are prepared as a left and right pair, and sliders 13 are attached to the element rows 50 of the pair of woven zipper stringers 20. In addition, a first fastener 11 and a second fastener 12 are provided at the front and rear ends of the left and right woven zipper stringers 20, respectively. This completes the manufacture of the concealed slide fastener 10 of this embodiment 1.

[0059] In this embodiment 1, in order to manufacture a zippered seat cover 1 in which a hidden slide fastener 10 is sewn to the surface material 6, the following sewing process is performed in which, before attaching the slider 13, the first fastener 11, and the second fastener 12 to the left and right pair of woven fastener stringers 20, the left and right woven fastener stringers 20 are sewn to the corresponding parts of the left and right surface material 6 of the seat cover 1.

[0060] In this sewing process, in order to sew the woven zipper stringer 20 to the seat cover 1, first, using a sewing machine (not shown), one of the pair of woven zipper stringers 20 is sewn to the surface material 6 that forms the seat cover 1.

[0061] In the sewing process of this embodiment 1, with the tape body portion 22 and the outer material 6 of the fastener tape 21 overlapping, the woven fastener stringer 20 and the outer material 6 are placed on the needle plate of the sewing machine and pressed down with the sewing machine foot. At this time, the fastener tape 21, which is folded in a U shape, is opened so that the angle between the element attachment portion 24 and the tape body portion 22 is large, and the element row 50, together with the element attachment portion 24 of the fastener tape 21, is introduced into the element guide groove formed in the sewing machine foot (not shown).

[0062] Then, the sewing machine is operated to intermittently feed the woven zipper stringer 20 and the outer material 6 along the feed direction of the sewing machine. At this time, the element row 50 and the element mounting portion 24 are continuously guided into the element guide groove of the sewing machine foot, so that the woven zipper stringer 20 is fed under the sewing machine foot while opening the U-shaped folded zipper tape 21.

[0063] Furthermore, in accordance with the feeding motion of the sewing machine, the sewing machine needle is repeatedly raised and lowered against the woven zipper stringer 20 and the outer material member 6, which are held down by the sewing machine foot. At this time, the sewing machine needle, through which the sewing thread is threaded, is inserted into the woven zipper stringer 20 and the outer material member 6 at regular intervals, preferably at a position close to the thick second warp thread 32 of the zipper tape 21, and between the two second warp threads 32. This creates a continuous sewn section 60 along the length of the zipper tape 21 using the sewing machine's sewing thread, and the woven zipper stringer 20 can be securely sewn to the outer material member 6 by this sewn section 60. As a result, one of the woven zipper stringers 20 is sewn to the outer material member 6 of the seat cover 1.

[0064] Furthermore, after sewing one of the woven zipper stringers 20 to the surface material 6, the other woven zipper stringer 20 of the hidden slide zipper 10 and another surface material 6 of the seat cover 1 are sewn together in the same manner as described above, thereby securely fixing the other woven zipper stringer 20 to the surface material 6 of the seat cover 1.

[0065] In this invention, the method and means of sewing the woven zipper stringer to the zipper attachment member, such as the outer material member 6, are not particularly limited, and the woven zipper stringer can be sewn to the zipper attachment member using various conventionally known methods and means.

[0066] By performing the sewing process described above, a seat cover 1 can be obtained in which the left and right woven zipper stringers 20 are sewn to each other. Subsequently, sliders 13 are attached to the left and right woven zipper stringers 20 sewn to the seat cover 1, and first fasteners 11 and second fasteners 12 are provided, thereby manufacturing a car seat cover 1 with a hidden slide fastener 10.

[0067] In this embodiment 1, a concealed slide fastener 10 may be manufactured by first attaching the slider 13, the first fastener 11, and the second fastener 12 to the left and right woven fastener stringers 20 to create the concealed slide fastener 10, and then sewing the left and right woven fastener stringers 20 of the obtained concealed slide fastener 10 to the seat cover 1.

[0068] In the zippered seat cover 1 of this embodiment 1, which is manufactured by the sewing process described above, the left and right surface members 6 of the seat cover 1 are butted against each other when the left and right element rows 50 are interlocked, as shown in Figure 3.

[0069] In this embodiment 1, the two thick second warp threads 32 woven into each of the left and right woven zipper stringers 20 are positioned in close proximity to the sewing section 60, at two locations, above and below the sewing section 60. This allows the left and right surface members 6 to be stably butted together, and also allows the state in which the surface members 6 are butted together to be stably maintained. As a result, the left and right woven zipper stringers 20 (especially the left and right element rows 50) that are in an interlocking state can be concealed by the left and right surface members 6 so that they are not visible from the outer surface side of the seat cover 1 (upper side in Figure 3).

[0070] Furthermore, in the zippered seat cover 1 of this embodiment 1, the left and right sewing sections 60 that sew the woven zipper stringer 20 and the surface material 6 are provided so as to penetrate the zipper tape 21 at positions close to each of the two second warp threads 32. Moreover, each sewing section 60 is provided so as to penetrate the respective zipper tape 21 at a position between the two second warp threads 32.

[0071] In this invention, the statement that the sewing portion 60 is provided in a position close to the second warp thread 32 means that the sewing portion 60 is provided in a position such that the number of warp threads 30 of the fastener tape 21 arranged between the sewing portion 60 and the second warp thread 32 is 4 or less, preferably 2 or less.

[0072] Furthermore, when describing the proximity using specific lengths (dimensions), the sewing portion 60 is positioned such that, when viewed in cross-section perpendicular to the length direction of the fastener tape 21, the distance (minimum distance) between the sewing portion 60 and the second warp thread 32, which is located on the side edge adjacent to the tape bend portion 23 of the element attachment portion 24, is 2 mm or less, preferably 1 mm or less. Also, the sewing portion 60 is positioned such that, when viewed in cross-section perpendicular to the length direction of the fastener tape 21, the distance (minimum distance) between the sewing portion 60 and the second warp thread 32, which is located on the side edge adjacent to the tape bend portion 23 of the tape body portion 22, is 3 mm or less, preferably 1 mm or less.

[0073] As described above, in the case of the zippered seat cover 1 of this embodiment 1, in which the sewing portion 60 is provided close to the second warp thread 32, even if a pulling force (lateral pulling force) is applied outward in the left-right direction to separate the left and right surface members 6 from each other while the left and right element rows 50 are engaged, the two thick second warp threads 32 arranged on each zipper tape 21 can hold down the sewing portion 60. In addition, the thick second warp threads 32 (especially the lower second warp thread 32 arranged on the element attachment portion 24) make it difficult for the tape bend portions 23 of the left and right zipper tapes 21 to move outward in the left-right direction. Therefore, it is possible to restrict or suppress the movement of the left and right surface members 6 outward in the left-right direction, making it easier to maintain the state in which the left and right surface members 6 are butted together.

[0074] Furthermore, in conventional concealed slide fasteners, for example, when a strong lateral pulling force is applied to the left and right outer material, as mentioned above, the strong lateral pulling force is transmitted from the sewing area to the warp threads of the fastener tape, which is positioned close to the sewing area, causing the warp threads to shift in the weft direction. As a result, conventional fasteners have suffered from problems such as gaps forming between the left and right outer material and between the left and right fastener tapes, or even the widening of these gaps, due to the displacement of the warp threads.

[0075] In contrast, in the concealed slide fastener 10 of this embodiment 1, the second warp threads 32 of the fastener tape 21 are formed to be thicker than the first warp threads 31. In particular, each second warp thread 32 of this embodiment 1 is formed to have a cross-sectional area perpendicular to the longitudinal direction of the second warp thread 32 that is large enough to prevent or suppress the displacement of the second warp thread 32 in the weft direction when the fastener tape 21 is subjected to the strong lateral pulling force described above.

[0076] Therefore, in the zippered seat cover 1 of this embodiment 1, even if the density of the weft threads 35 in the longitudinal direction of the zipper tape 21 is small, as in conventional woven zipper stringers, the thick second warp threads 32 are positioned close to the sewing portion 60, which effectively prevents or suppresses displacement of the first warp threads 31 and the second warp threads 32 in the weft direction when a strong lateral pulling force is applied to the left and right surface members 6.

[0077] In particular, in this embodiment 1, since the second warp thread 32 is arranged in close proximity to the top and bottom of the sewing section 60, it is possible to effectively prevent misalignment of the first warp thread 31 arranged in the tape body section 22 of the fastener tape 21 and misalignment of the first warp thread 31 arranged in the element attachment section 24. As a result, it is possible to effectively prevent the formation of a gap between the left and right surface members 6 that would expose the element row 50 and the fastener tape 21 due to misalignment of the warp thread 30, and it is also possible to make it difficult to expose the element row 50 from between the left and right fastener tapes 21.

[0078] Furthermore, in this embodiment 1, since the two thick second warp threads 32 are arranged on each of the left and right fastener tapes 21 (especially near the tape bend portion 23 of the fastener tape 21), a relatively long vertical distance can be secured from the outer surface (upper surface) of the left and right skin members 6 that is exposed to the outside to the position of the interlocking left and right element rows 50. As a result, even if a very strong lateral pulling force is applied to the left and right skin members 6, and a gap is formed between the left and right skin members 6 and between the left and right fastener tapes 21, it is made difficult for light to reach the left and right element rows 50 located beneath the fastener tapes 21, and as a result, it is made difficult for the left and right element rows 50 to be seen from the outside.

[0079] As described above, the zippered seat cover 1 of this embodiment 1 has excellent concealment properties because, even when a strong lateral pulling force is applied to the left and right surface members 6, the interlocked left and right element rows 50 and the zipper tape 21 can be covered and hidden (or made difficult to see) by the left and right surface members 6. Therefore, by using the zippered seat cover 1 of this embodiment 1, it is possible to effectively prevent the appearance quality of the seat cover 1, and furthermore, the appearance quality of the seat to which the seat cover 1 is attached, from being reduced by the exposure of the element rows 50.

[0080] In this embodiment 1, the second warp thread 32, which is thicker than the first warp thread 31, is arranged as described above in the warp thread 30 that is positioned closest to the tape bend portion 23 among the multiple warp threads 30 that form the tape body portion 22, and in one of the three upper fixing warp threads 41 that are positioned on the interlocking head 52 side of the positioning warp thread 44 in the element attachment portion 24.

[0081] However, in the present invention, the position in which the second warp thread 32 is arranged is not particularly limited as long as it is close to the sewing section 60, and can be changed according to the size and application of the slide fastener. For example, Figure 4 shows a woven fastener stringer 20c, which is a modified example in which the position of the second warp thread 32 arranged in the element attachment section 24 is changed from that of the fastener stringer 20 of Example 1.

[0082] In this modified woven fastener stringer 20c, the second warp thread 32, which is thicker than the first warp thread 31, is arranged on the side edge of the tape body portion 22 adjacent to the tape bend portion 23 and on the side edge of the element attachment portion 24 adjacent to the tape bend portion 23. In particular, in this modified case, the second warp thread 32 of the element attachment portion 24 is used as one of the two upper fixing warp threads 41 arranged between the positioning warp thread 44 closest to the interlocking head 52 and the tightening warp thread 43 adjacent to the positioning warp thread 44.

[0083] Even with this modified woven fastener stringer 20c, since the two thick second warp threads 32 are positioned close to the sewing section 60, when a strong lateral pulling force is applied to the left and right surface members 6, it is possible to prevent or suppress displacement of the first warp thread 31 and the second warp thread 32 in the weft direction. Therefore, it is possible to effectively prevent the formation of a gap between the left and right surface members 6 that would expose the element row 50 and the fastener tape 21, and it is also possible to make it difficult to expose the element row 50 from between the left and right fastener tapes 21.

[0084] In the modified woven fastener stringer 20c, the second warp thread 32 of the tape body portion 22 is used as the warp thread 30 that is closest to the tape bend portion 23 among the multiple warp threads 30 that form the tape body portion 22, similar to the woven fastener stringer 20 of Embodiment 1 described above. However, in the present invention, the second warp thread may be used as, for example, a warp thread that is placed in the tape bend portion, or as the second or third closest warp thread from the tape bend portion among the multiple warp threads that form the tape body portion. [Examples]

[0085] Figure 5 is a schematic cross-sectional view showing a concealed slide fastener according to this embodiment 2. Figure 6 is a schematic cross-sectional view showing the main part of a seat cover manufactured by sewing the concealed slide fastener to the surface material in this embodiment 2. In this embodiment 2 and the concealed slide fasteners 10a, 10b and zippered seat covers 2, 3 of embodiment 3 described later, parts or components that are substantially the same as those of the concealed slide fastener 10 and zippered seat cover 1 of embodiment 1 described above will be represented by the same reference numerals, and their explanation will be omitted.

[0086] The concealed slide fastener 10a of this embodiment 2 comprises at least a pair of left and right concealed type woven fastener stringers 20a and sliders (not shown) attached to the element rows 50 of the left and right woven fastener stringers 20a. The sliders used in this embodiment 2 are formed substantially the same as the slider 13 described in the above-mentioned embodiment 1. In addition, in the concealed slide fastener 10a of this embodiment 2, as in the above-mentioned embodiment 1, dedicated opening and closing members formed to be attachable to and detachable from the left and right element rows 50 may be used instead of sliders.

[0087] In this embodiment 2, each left and right woven fastener stringer 20a has a fastener tape 21a having a woven structure formed by a plurality of warp threads 30 and weft threads 35, and a plurality of fastener elements 51 that are woven into and fixed to a part of the fastener tape 21a.

[0088] In this embodiment 2, the warp threads 30 forming the fastener tape 21a consist of a plurality of first warp threads 31 having the same thickness as each other, and one second warp thread 32 that is thicker than the first warp threads 31. This one second warp thread 32 is positioned on the side edge of the element attachment portion 24 of the fastener tape 21a adjacent to the tape bend portion 23.

[0089] In other words, the woven fastener stringer 20a of this embodiment 2 is formed by replacing the second warp thread 32, which was arranged in the tape body portion 22 of the fastener tape 21, with a first warp thread 31 that is thinner than the second warp thread 32, compared to the hidden slide fastener 10 of the aforementioned embodiment 1. To put it another way, the number of thick second warp threads 32 used in the fastener tape 21a of this embodiment 2 is only one, not two as in the fastener tape 21 of the aforementioned embodiment 1. The woven fastener stringer 20a of this embodiment 2 is formed in the same way as the woven fastener stringer 20 of the aforementioned embodiment 1, except that the second warp thread 32 arranged in the tape body portion 22 of the fastener tape 21a has been replaced with a first warp thread 31.

[0090] In this embodiment 2, the concealed slide fastener 10a is manufactured by sewing the woven fastener stringer 20a to the surface material 7 of the seat cover 2 using a sewing machine, similar to the case of embodiment 1 described above, thereby producing the seat cover 2 with a fastener shown in Figure 6.

[0091] In the zippered seat cover 2 manufactured in this embodiment 2, the left and right surface members 7 of the seat cover 2 are abutting against each other when the left and right element rows 50 are engaged, so the left and right element rows 50 are concealed by the seat cover 2.

[0092] Furthermore, in this embodiment 2, the left and right sewing sections 60 that sew the woven zipper stringer 20a and the outer material 7 together are positioned above the second warp thread 32 located in the element attachment section 24 (in other words, closer to the tape body portion 22 of the zipper tape 21a than the second warp thread 32).

[0093] As a result, in this embodiment 2, when a strong lateral pulling force is applied to the left and right surface members 7, it is possible to effectively prevent or suppress the displacement in the weft direction between the position of the second warp thread 32 and the positions of the multiple first warp threads 31 arranged in the element attachment portion 24. Therefore, it is possible to prevent or suppress the formation of a gap between the left and right surface members 7 that would expose the element row 50 and the fastener tape 21a due to the displacement of the warp threads 30.

[0094] Furthermore, in this embodiment 2 as well, since the thick second warp threads 32 are arranged on each of the left and right fastener tapes 21a, even if a small gap is formed between the left and right surface members 7, it is possible to make it difficult for light to reach the left and right element rows 50 located beneath the fastener tapes 21a, and thus it is possible to make it difficult for the left and right element rows 50 to be seen from the outside. Therefore, the zippered seat cover 2 of this embodiment 2 has excellent concealment properties. [Examples]

[0095] Figure 7 is a schematic cross-sectional view showing a concealed slide fastener according to this embodiment 3. Figure 8 is a schematic cross-sectional view showing the main part of a seat cover manufactured by sewing the concealed slide fastener to the surface material in this embodiment 3.

[0096] The concealed slide fastener 10b of this embodiment 3 comprises at least a pair of left and right concealed type woven fastener stringers 20b, and sliders (not shown) attached to the element rows 50 of the left and right woven fastener stringers 20b. Each of the left and right woven fastener stringers 20b has a fastener tape 21b having a woven structure formed by a plurality of warp threads 30 and weft threads 35, and a plurality of fastener elements 51 that are woven into and fixed to a part of the fastener tape 21b.

[0097] In this embodiment 3, the warp threads 30 forming the fastener tape 21b consist of a plurality of first warp threads 31 having the same thickness as each other, and one second warp thread 32 that is thicker than the first warp threads 31. This one second warp thread 32 is positioned on the side edge of the tape body portion 22 of the fastener tape 21b adjacent to the tape bend portion 23.

[0098] In other words, the woven fastener stringer 20b of this embodiment 3 is formed by replacing the second warp thread 32, which was arranged in the element attachment portion 24 of the fastener tape 21 in the concealed slide fastener 10 of embodiment 1, with the first warp thread 31. However, apart from this change to the first warp thread 31, it is formed substantially the same as the woven fastener stringer 20 of embodiment 1.

[0099] In the zippered seat cover 3 of this embodiment 3, which is manufactured using such a concealed slide fastener 10b, the left and right surface members 8 of the seat cover 3 are butted against each other when the left and right element rows 50 are engaged, so the left and right element rows 50 are concealed by the seat cover 3.

[0100] Furthermore, each of the left and right sewing sections 60 is positioned below the second warp threads 32 arranged in the tape body 22 (in other words, closer to the element attachment section 24 of the fastener tape 21b than the second warp threads 32). This effectively prevents or suppresses the displacement in the weft direction between the position of the second warp threads 32 and the positions of the multiple first warp threads 31 arranged in the tape body 22 when a strong lateral pulling force is applied to the left and right surface members 8. As a result, it is possible to prevent or suppress the formation of gaps between the left and right surface members 8 that expose the element row 50 and the fastener tape 21b due to displacement of the warp threads 30.

[0101] Furthermore, in this embodiment 3 as well, since the thick second warp thread 32 is arranged on the fastener tape 21b, the left and right element rows 50 located beneath the fastener tape 21b can be made less visible from the outside, similar to the cases of embodiments 1 and 2 described above. Therefore, the zippered seat cover 3 of this embodiment 3 has excellent concealment properties.

[0102] Furthermore, in the concealed slide fastener 10b of this embodiment 3, since the second warp thread 32 is arranged only in the tape body portion 22 of the fastener tape 21b, when sewing the woven fastener stringer 20b to the seat cover 3 using a sewing machine, it is easier to introduce the element attachment portion 24 and element row 50 of the fastener tape 21b into the element guide groove provided in the sewing machine foot. Therefore, compared to, for example, the cases of embodiments 1 and 2 described above, sewing can be performed more smoothly. [Explanation of Symbols]
