[Problems to be solved by the invention]

In Patent Documents 1 and 2, a stretchable spun yarn is woven into a central region of a chain cloth having a relatively wide width in a chain cloth width direction of a zipper chain cloth of a knitting structure. Thereby, a sufficient amount of expansion and contraction in the width direction of the chain cloth can be obtained. However, when sewing an object such as a cloth in the center region of the chain cloth, in terms of the sewing position, the stretching force of the chain cloth region farther from the fastener element is practically not used.

In Patent Document 2, in a zipper chain cloth of a woven structure, a stretchable yarn is used as a weft yarn. In the woven zipper chain fabric, one yarn is used as the weft yarn. Therefore, a large amount of stretchable yarn is used as the weft yarn. Further, in Patent Document 2, the stretchability of the stretchable weft yarn is locally restricted by sewing the fastener elements or the like on the fastener chain cloth. In this respect, the stretchable yarn is used in vain.

As can be seen from the above description, the inventors of the present invention have found the following new problems: while eliminating the useless use of stretchable yarns as much as possible and reducing the use of stretchable yarns, the necessary sufficient stretchability of the fastener chain is ensured.

[Effect of the invention]

According to one aspect of the present invention, the useless use of the stretchable yarn can be suppressed, and at this time, the warp interval near the fastener element can be narrowed to improve the appearance and / or characteristics of the fastener chain.

Hereinafter, a non-limiting embodiment of the present invention will be described with reference to FIGS. 1 to 8. Various features included in the disclosed embodiments can be combined in various ways, and each feature can also be applied to slide fasteners other than the disclosed types of slide fasteners. In principle, overlapping descriptions between the embodiments are omitted. With reference to the drawings, the description of the invention is the main purpose, and it may be simplified for the convenience of drawing.

FIG. 1 is a schematic front view of a slide fastener 50. FIG. FIG. 2 is a schematic diagram showing a state in which the left and right fastener elements 20 are combined in the slider 40 of the slide fastener 50. FIG. 3 is a schematic cross-sectional view of a fastener chain, and the flange portion 44 of the slider 40 is also shown together. FIG. 4 is a schematic view showing a warp knitting structure of the fastener chain fabric 10. FIG. 5 is a schematic view showing the warp knitting structure of the zipper chain fabric 10, corresponding to a state where the zipper chain fabric 10 extends in the width direction of the chain fabric. Fig. 6 is a schematic diagram showing the appearance of each yarn constituting a warp knitting structure of a zipper chain cloth. FIG. 7 is a photograph showing the left and right zipper chain belts 30 combined. FIG. 8 is a schematic view showing a state in which the slide fastener 50 is sewn on the attached bodies 71 and 72.

In this specification, the direction of a zipper is defined as follows. The forward and backward directions are consistent with the moving direction of the slider for opening and closing the zipper. By closing the zipper before the slider, that is, the left and right zipper chains and the left and right zipper elements are combined. After the slider is opened, the zipper is opened, that is, the combination of the left and right zipper chains and the left and right zipper fastener elements are released. The left-to-right direction is consistent with the horizontal arrangement direction of the zipper chain and zipper chain teeth which become combined and uncoupled by the movement of the slider in the forward and backward directions. The left-right direction is orthogonal to the front-rear direction and parallel to the chain cloth surface of the zipper chain. The vertical direction is a direction orthogonal to the front-rear direction and the left-right direction. Furthermore, these directions can be redefined with reference to the following description.

The warp direction and warp loop direction of the zipper chain cloth containing the warp knitting organization are the same as those of the zipper before and after the above description. The weft direction and weft loop direction of the zipper chain cloth including the warp knitting structure are the same as the left and right directions described above with respect to the zipper. The warp and warp directions can be used alternatively. Likewise, weft and weft loop directions can be used alternatively. The warp loop is a portion in which a loop (yarn loop) is continuously formed along an axis extending in the warp direction.

As shown in FIG. 1, the slide fastener 50 includes a pair of left and right slide fastener chains 30 and one or more sliders 40 for opening and closing the left and right slide fastener chains 30. Each of the fastener chain belts 30 includes a knitting structure, a zipper chain fabric 10 with a warp knitting structure, and a zipper element 20 provided on the zipper chain fabric 10. As shown in FIGS. 4 and 6, the warp knitting structure of the zipper chain fabric 10 includes a plurality of knitting yarns such as a chain knitting yarn 61, a Tricot knitting yarn 62, and a sandwich yarn 63, but it is not necessarily limited thereto. The warp knitting structure of the fastener chain fabric 10 may have additional types of knitting yarns, for example, warp knitting yarns and heavy warp knitting yarns.

The fastener element 20 is provided for the side edge part of the fastener chain fabric 10 extended in the front-back direction. As the fastener element 20, a ring shape is shown, but it goes without saying that the type of the fastener element 20 should not be limited to this. It is also easy to imagine a form in which metal or resin fastener elements are fixed to the side edge portions of the fastener chain fabric 10 at a certain interval. In the form in which the fastener element 20 is a loop-shaped element, typically, the loop-shaped element is sewn on the fastener chain fabric 10, specifically, the following first chain fabric region 11 (see FIG. 3) by stitching. . It is also conceived that the knitting of the ring-shaped sprocket and the zipper chain fabric 10 is knitted into the warp knitting structure of the zipper chain fabric 10. Furthermore, in the example shown in the figure, a front stop is provided at the front end of the fastener element 20, and a rear stop is provided at the rear end of the fastener element 20.

The slider 40 includes an upper wing plate 41, a lower wing plate 42, a connecting post (not shown) connecting the upper wing plate 41 and the lower wing plate 42, a pull-tab mounting portion 43, and a pull-tab 46. The upper wing panel 41 is provided with a flange portion 44 for determining a movement path of the left and right fastener element 20. The gap between the flange portion 44 of the upper wing plate 41 and the flange portion 45 of the lower wing plate 42 allows the fastener chain fabric 10 to pass through. Furthermore, it is also conceived that a flange portion for determining a movement path of the left and right fastener element 20 is provided on the lower wing plate 42. Similarly, it is also conceived that the flange portions for determining the movement paths of the left and right fastener elements 20 are divided into upper wing plates 41 and lower wing plates 42 and provided. The slider 40 may be made of resin, metal, or ceramic, but it should not be limited to this.

As described above, the zipper chain fabric 10 includes a warp knitting structure. In several forms including the illustrated examples, the warp knitting structure of the zipper chain fabric 10 includes at least a chain knitting yarn 61, a Tricot knitting yarn 62, and a pinning yarn. 63. It is not necessarily limited to this, but as shown in FIG. 4, all warp loops included in the warp knitting structure of the zipper chain fabric 10 include the loop (s) of the chain knitting yarn 61 and the loop (s) of the Tricot knitting yarn 62 The combination of the loops, and the part (s) of the interlocking yarns 63 that are engaged with the loops of the chain knitting yarn 61 and / or the loops of the Tricot knitting yarn 62. It is assumed that any one of the chain knitting yarn 61 and the Tricot knitting yarn 62 is omitted in one or more warp loops. It is assumed that the yarn 63 is omitted in one or more warp loops.

The warp knitting structure of the fastener chain fabric 10 is formed by continuously knitting a loop (loop) in a warp direction. In order to form a warp loop, the chain knitting yarn 61 is knitted in such a manner that the loops are continuous in the warp direction. That is, one warp loop is constituted by the continuity of the loops of one chain knitting yarn 61. In other words, the fastener chain fabric 10 includes a plurality of warp loops that are individually configured by a plurality of chain knitting yarns 61.

Tricot knitting yarn 62 is knitted in a continuous warp direction like the chain knitting yarn 61, but unlike the chain knitting yarn 61, a loop is alternately formed in two adjacent warp loops. Also, please note that the appearance of the Tricot knitting yarn 62 forming a knitted fabric while forming a loop in the warp direction is not limited to this description or the example of the drawing, and may be various other forms. At the same time, weaving of each of Tricot knitting yarn 62 and chain knitting yarn 61 is performed, and the two are fastened to form a knitted fabric during knitting. The spun yarn 63 extends in the warp direction while swinging or meandering with a swing width of two or more warp loops. The spun yarn 63 is different from the chain knitting yarn 61 and the Tricot knitting yarn 62, and is a yarn that does not form a loop itself. The knitting yarn 63 is knitted and knitted into the stitches of the chain knitting yarn 61 and / or the stitches of the Tricot knitting yarn 62 at the intersections with the warp loops, and / or knitted and reversed in the reverse direction in the weft direction. Loops to chain knitting yarn 61 and / or loops of Tricot knitting yarn 62.

As shown in FIGS. 3 and 4, the fastener chain fabric 10 includes a first chain fabric region 11, a second chain fabric region 12, and a third chain fabric region 13. The first chain cloth area 11 is a chain cloth area knitted with a non-stretchable spun yarn 63a with a swing width spanning a plurality of warp loops. Although the first chain fabric region 11 has a little stretchability in the weft direction based on the knitting structure, it does not exhibit sufficient stretchability in the weft direction due to the non-stretchable interlocking yarn 63a. That is, the first chain fabric region 11 can be referred to as a non-stretchable chain fabric region that does not have elasticity substantially in the weft direction. A fastener element 20 is provided on the first chain cloth region 11. In addition, the knitting structure of the first chain fabric region 11 is a warp knitting structure, so that the elasticity in the latitudinal direction obtained is originally small.

The second chain fabric region 12 is a chain fabric region knitted and knitted with a non-stretchable spun yarn 63b with a swing width spanning a plurality of warp loops, and is provided away from the fastener element 20 in the weft direction (chain fabric width direction). Although the second chain fabric region 12 has a little stretchability in the weft direction based on the knitting structure, it does not exhibit sufficient stretchability in the weft direction due to the non-stretchable yarn 63b. That is, the second chain fabric region 12 can be referred to as a non-stretchable chain fabric region that does not have elasticity in the weft direction.

The third chain fabric region 13 is a chain fabric region knitted with a stretchable spun yarn 63c with a swing width spanning a plurality of warp loops. The third chain fabric region 13 has the weft stretchability based on the knitting structure and stretchability of the sandwich yarn 63c. That is, the third chain fabric region 13 is a stretchable chain fabric region having sufficient elasticity in the weft direction. The stretchability of the third chain fabric region 13 in the weft direction is mainly obtained based on the stretchable gusset 63c. In other words, the third chain fabric region 13 is different from the first and second chain fabric regions 11 and 12 and includes a stretchable clip 63c instead of a non-stretchable clip 63a, 63b. This ensures and promotes the zonal stretchability of the third chain fabric region 13. The third chain fabric region 13 is provided between the fastener element 20 and the second chain fabric region 12. The fastener chain fabric 10 can be divided into the first to third chain fabric regions as described above. Furthermore, it is assumed that the first to third chain fabric regions 11 to 13 are in the form of non-overlapping divided regions, or a form in which they are partially overlapped.

In the form shown in FIG. 4, the first chain cloth region 11 includes four warp loops, the second chain cloth region 12 includes nine warp loops, and the third chain cloth region 13 includes seven warp loops. The first chain fabric region 11 and the third chain fabric region 13 overlap only two warp loops 9a, 9b. The second chain fabric region 12 and the third chain fabric region 13 overlap only one warp loop 9c. In several forms, the relationship between the number of warp loops included in the first chain cloth region 11 <the number of warp loops included in the third chain cloth region 13 <the number of warp loops included in the second chain cloth region 12 is established .

The non-stretchable spun yarn 63a knitted into the first chain fabric region 11 is, for example, a polyester yarn having a fineness of 84 cents to 660 cents. The non-stretchable spun yarn 63b knitted into the second chain fabric region 12 is, for example, a polyester yarn having a fineness of 84 cents to 660 cents. The stretchable spun yarn 63c knitted into the third chain region 13 is, for example, a polyurethane yarn having a fineness of 84 cents to 660 cents.

By knitting the non-stretchable splicing yarn 63a in the first chain fabric region 11, the weft expansion and contraction of the first chain fabric region 11 can be suppressed, and the stable fixing of the fastener element 20 to the first chain fabric region 11 is promoted. Or sewing. Similarly, by knitting a non-stretchable splicing yarn 63b into the second chain fabric region 12, it is possible to suppress the weft expansion and contraction of the second chain fabric region 12 and promote the mounted body such as cloth or leather against the second chain fabric. Zone 12 stable sewing. The third chain fabric region 13 is knitted with a stretchable spun yarn 63c to obtain a partial weft expansion and contraction in the third chain fabric region 13.

As shown in FIG. 4, when the second chain fabric region 12 is not pulled away from the fastener element 20 in the weft direction, the warp loop interval W13 in the third chain fabric region 13 is restrained by the elasticity of the spliced yarn. The warp interval W11 in the first chain cloth region 11 and the warp interval W12 in the second chain cloth region 12 are smaller. On the other hand, as shown in FIG. 5, when the second chain cloth region 12 is pulled away from the fastener element 20, the warp loop interval W13 in the third chain cloth region 13 is larger than the warp loop in the first chain cloth region 11. The interval W11 and the warp interval W12 in the second chain fabric region 12. That is, when the second chain fabric region 12 is pulled away from the fastener element 20, the warp loop interval of the third chain fabric region 13 resists the restraint caused by the elasticity of the third chain fabric region 13 (ie, Reduce the force of the warp interval) to change from the first interval smaller than the warp interval of the second chain fabric region 12 to the second interval larger than the warp interval of the second chain fabric region 12. The stretchable sandwich yarn 63c in the third chain fabric region 13 extends in the weft direction, thereby ensuring the weft elasticity in the third chain fabric region 13.

In the present embodiment, the third chain fabric region 13 woven with stretchable spun yarn 63c is provided between the fastener element 20 and the second chain fabric region 12, and the third chain fabric region 13 in the weft direction The width is smaller than the width of the second chain fabric region 12 in the weft direction. Further, when the second chain fabric region 12 is pulled away from the fastener element 20 in the weft direction, the warp loop interval of the third chain fabric region 13 resists the restraint caused by the stretchable yarn of the third chain fabric region 13 The first interval smaller than the meridian interval of the second chain cloth region 12 can be changed to a second interval larger than the meridian interval of the second chain cloth region 12 (refer to the change of the meridian interval W13 in FIGS. 4 and 5). ). Thereby, it is possible to suppress the case of attaching the body such as a cloth or leather to the third chain region 13, and to prevent the stretchable gusset 63c from becoming useless in whole or in part.

When the second chain cloth region 12 is pulled away from the zipper element 20, the warp interval of the third chain cloth region 13 is changed from the first interval to the second interval, which means that the first chain cloth region 12 is not pulled away from the zipper element 20 When the second chain cloth region 12 is used, the warp interval of the third chain cloth region 13 is maintained to be (less than the second chain cloth region 12's warp interval) the first interval. By narrowing the third chain fabric region 13 in the weft direction, it is possible to further reduce the possibility that the third chain fabric region 13 of the stretchable spun yarn 63c is sewn into a woven fabric, an attached body such as leather or the like.

Furthermore, in several forms, when the second chain cloth region 12 is not pulled away from the zipper element 20 and when the second chain cloth region 12 is pulled away from the zipper element 20 The width of the third chain fabric region 13 in the weft direction is smaller than the width of the second chain fabric region 12 in the weft direction. The third chain fabric region 13 is directly adjacent to the fastener element 20 provided in the first chain fabric region 11, for example, by sewing the first chain fabric region 11 with a seam, and the fastener element 20 is connected to the second chain. The cloth regions 12 are exposed.

Maintaining the warp interval of the third chain fabric region 13 as the first interval as described above means that the knitting yarn (chain knitting yarn, green yarn) of the zipper chain cloth 10 is raised at the contact portion with the flange portion 44 of the slider 40. Special knitting yarns, and yarns). Thereby, abrasion of the fastener chain fabric 10 caused by friction with the slider 40 is suppressed. Further, by maintaining the warp loop interval of the third chain fabric region 13 as the first interval as described above, the third chain fabric region 13 is exposed between the fastener element 20 and the attached bodies 71 and 72 such as cloth or leather. The appearance of a high-density and strong-looking cloth is also obtained (see FIG. 8). In addition, as described above, the warp loop interval of the third chain fabric region 13 is kept small by clamping the yarn 63c. This can be achieved by sandwiching the third chain fabric region 13 in a stretchable elastic yarn. .

The first chain cloth region 11 includes a non-stretchable one of the sandwich yarns 63a, and one sandwich yarn 63a is knitted and knitted with a swing width across a plurality of (4) warp loops. The second chain fabric region 12 includes a plurality of non-stretchable yarns 63b, and each of the yarns 63b is knitted and knitted with a swing width across a plurality of (4) warp loops. A plurality of clamped yarns 63b are clamped at a warp interval in the weft direction. The third chain fabric region 13 includes two stretchable yarns 63c, and each of the yarns 63c is knitted with a swing width spanning a plurality of (4) warp loops. Although not necessarily limited to this, the swing amplitudes of the clamped yarns are equal. In other words, the number of warp loops spanned by the meandering yarn 63a = the number of warp loops spanned by the meandering yarn 63b = the number of warp loops spanned by the meandering yarn 63c The relationship between the numbers holds. Regarding the number of yarns 63, the relationship between the second chain fabric region 12> the third chain fabric region 13> the first chain fabric region 11 is established. That is, the number of yarns 63 included in the second chain fabric region 12 is the largest, the number of yarns 63 included in the first chain fabric region 11 is the smallest, and the number of yarns 63 included in the third chain fabric region 13 The number is in between.

A stretchable yarn is a yarn that can be stretched more than a non-stretchable yarn. For example, stretchable sandwich yarns are rubber yarns, polyurethane yarns, and polyether / ester yarns. Stretch yarn is also called elastic yarn. Non-stretchable yarns are yarns that expand or contract to a lesser extent than stretchable yarns. For example, non-stretchable sandwich yarns are nylon yarns, acrylic yarns, polyester yarns, and the like. If it is stated without limitation, the stretchable yarn has a maximum elongation of 40 to 150% at the standard time. On the other hand, non-stretchable yarns have a maximum elongation of 10% to 40% at the standard time. The standard time means that the yarn is not wet. The elongation is measured in accordance with JIS L-1013. Furthermore, the sandwiched yarn may be a monofilament or a multifilament yarn.

As shown in FIG. 4, it is assumed that the first chain cloth region 11 and the second chain cloth region 12 overlap, that is, the stretchable yarn 63 c of the third chain cloth region 13 and the non-stretchable yarn of the first chain cloth region 11 The yarn 61a is knitted into the common warp loops 9a, 9b. In the common warp loops 9a and 9b, the sandwiched yarns 63a of the first chain fabric region 11 and the sandwiched yarns 63c of the third chain fabric region 13 are knitted alternately in the warp direction. Typically, the non-stretchable sandwich yarn 63a is a yarn that is stronger than the stretchable sandwich yarn 63c (for example, the tensile strength is stronger). Therefore, in the common warp loops 9a and 9b, in addition to the stretchable clip yarn 63c, there is also a non-stretchable clip yarn 63a, thereby improving the slide fastener 40 of the fastener chain 10, especially the flange portion thereof. 44 abrasion resistance (refer to Figure 3). In addition, the flange portion 44 of the slider 40 can be moved in a state of being in contact with any one or both of the common warp loops 9a, 9b. The warp loops 9a, 9b may also be referred to as slider contact areas. In the slider contact area, a stretchable clip yarn 63c and a non-stretchable clip yarn 63a are mixed.

Although it is not necessarily limited to this, the knitting of the knitting yarn 63 of the warp loops 9a, 9b can be performed by the loop of the chain knitting yarn 61 and / or the stitch of the Tricot yarn 62 and the knitting yarn 63. Reached. The number of the common warp loops 9a and 9b is not limited to two, and may be one or more or two or more.

As shown in FIG. 4, the stretchable sandwich yarn 63 c of the third chain fabric region 13 and the non-stretchable sandwich yarn 63 b of the second chain fabric region 12 are knitted into a common warp loop 9 c. Similarly to the above description of the relationship between the first chain cloth region 11 and the third chain cloth region 13, it can be understood that the second chain cloth region 12 and the third chain cloth region 13 overlap. The number of common warp circles 9c is not limited to one, and may be one or more or two or more.

FIG. 7 is a photograph showing the left and right zipper chain belts 30 combined. As described above, in a certain fastener chain belt 30, when the second chain fabric region 12 is not pulled away from the fastener element 20, the warp interval of the third chain fabric region 13 is kept smaller than that of the second chain fabric region 12. The first interval of the meridian interval. As a result, as shown in FIG. 7, the second chain fabric region 12 is configured as a mesh region, and the third chain fabric region 13 is configured as a non-mesh region. The third chain cloth region 13 exposed between the fastener element 20 and the attached bodies 71 and 72 such as cloth or leather has a high-density and strong-looking appearance (see FIG. 8). The mesh region is a chain fabric region in which a plurality of holes arranged in a two-dimensional pattern are opened. The non-mesh region is a chain region in a state where a plurality of holes arranged in a two-dimensional shape are substantially closed.

Furthermore, as described above, when the second chain fabric region 12 is pulled away from the fastener element 20 in a certain zipper chain belt 30, the warp interval of the third chain fabric region 13 is resisted by the third chain fabric region. The restraint caused by the stretchable sandwich yarn of 13 can be changed from the first interval smaller than the warp interval of the second chain fabric region 12 to the second interval larger than the warp interval of the second chain fabric region 12. Therefore, when the second chain fabric region 12 is pulled away from the fastener element 20 in a certain fastener chain 30, the third chain fabric region 13 is partially configured as a mesh region.

In order to manufacture the zipper chain cloth 10, various general or special knitting machines can be used.
