Description

Zipper chain with braided chain

The present invention relates to a zipper chain belt having a knitted fabric chain. Further, the present invention relates to a zipper chain and a zipper using the zipper tape.

The zipper is used not only for daily necessities such as clothing items, handbags, shoes, and miscellaneous goods, but also for the switching parts of articles in industrial products such as water storage tanks, fishing nets, and space garments.

In general, the zipper system mainly includes three parts, namely, a pair of elongated chain cloths, a meshing portion of the zipper sewn along one side edge of each of the chain cloths, that is, a plurality of sprocket teeth, and by meshing the sprocket teeth And a slider that separates and controls the opening and closing of the zipper.

The chain zipper for zippers (hereinafter referred to as "zipper chain cloth") includes a chain main body portion that is sewn to the main body portion of the article, and a sprocket attachment portion that is a portion that attaches the sprocket. In the element attaching portion, a fastener element is attached by a suture. At the end of the main body of the chain fabric, a woven yarn for preventing loosening can be provided. The chain cloth on which the fasteners are attached is called a fastener chain.

As a fastener chain cloth, a fabric chain fabric has been used in the past, and in recent years, a knitted fabric fabric having a warp knitted fabric has been widely used because it is excellent in flexibility and shape stability as compared with a fabric.

In order to improve the characteristics of the knitted fabric, various techniques have been proposed so far, and there is a technique for improving the characteristics by making a part of the yarn constituting the warp knitting tissue thick.

For example, Japanese Laid-Open Patent Publication No. SHO 59-29525 (Patent Document 1) discloses a zipper having a continuous element such as a zigzag-shaped sprocket which is sandwiched by a backing and sewn with a stitch. A zipper with a stable meshing state can be obtained without the sprocket teeth being displaced from the direction of the chain cloth.

According to Patent Document 1, the sprocket can be firmly attached by forming the warp of the side on which the sprocket is attached to be higher than and wider than the other warp. Further, as a specific example, it is disclosed that a side edge portion of a continuous sprocket of a type in which a warp is held is attached, and a warp knitting yarn between the first stitch row and the second stitch row and a second stitch row and a second stitch are provided. The crocheted knitting yarn of the 3-needle row is thicker than the other yarns.

In the Japanese Patent Publication No. Sho 52-18616 (Patent Document 2), a textile belt for zipper manufacture is disclosed as a belt edge portion for reinforcing a support belt to each other to form a wide fabric belt. Further, the roving is used as a crochet knitting yarn, a deformed heavy knitting yarn, and a mat yarn defining the edge portion of the belt, whereby the strength and elasticity of the support belt can be improved.

Japanese Patent Publication No. Hei 9-318 (Patent Document 3) proposes a warp-knit fabric for a slide fastener, which is provided with a plurality of warp-knitted warp-knit fabrics arranged in a longitudinal direction, and is characterized in that: The sprocket mounting portion is woven from a longitudinally non-stretched woven structure (in the embodiment, a woven structure in which crocheted knitting yarn is interlaced with other knitting yarns), and the knitting yarn is knitted on the outer side of the woven tissue. In the case of a coarse knitting yarn, the main body of the chain fabric is woven from a braided structure that can be stretched in the longitudinal direction (in the embodiment, a knitted fabric in which a single-knit yarn of a web is interwoven with other knitting yarns of a multifilament yarn). And the outer edge of the woven tissue is formed by a woven structure in which two coarse knitting yarns are interwoven. According to this, the sprocket mounting portion is a longitudinally non-stretched woven structure, and the edge portion thereof is reinforced, so that the sprocket can be attached in a stable state, so that the meshing of the sprocket can be performed accurately and smoothly.

The above prior art is not aimed at reducing the weight of the zipper, so there is no suggestion for the decision-making of the lightweighting. Portable windbreaker or Ladies' Lace, baby cardigan for outdoor sports for cycling, cycling, and tracking (outdoor sports) Among the items that are highly valued, it is advantageous to be able to reduce the weight of the zipper while maintaining the strength.

On the other hand, in the fastener element attached to the zipper chain cloth, there are a separate sprocket represented by a metal sprocket and a resin sprocket which is formed by molding on a chain cloth, or a resin sprocket which is formed in a loop shape. The continuous chain teeth are represented, and the resin elements of the loop-shaped fastener are not only light but also have high flexibility. Preferably, the portable article as described above can be easily folded and stored in a pocket, etc. Therefore, on the basis of realizing the weight reduction of the zipper, on the one hand, the type of the sprocket used is also considered, and on the other hand, the zipper chain is continuously pursued. The improvement of the cloth is more favorable.

Therefore, one of the problems of the present invention is to provide a fastener chain which is made of a resin-made chain fabric and a loop-shaped fastener element, and which has both a light and a strong zipper. One of the other problems of the present invention is to provide a zipper chain comprising such a zipper chain. Still another object of the present invention is to provide a zipper comprising such a zipper chain.

In order to reduce the weight of the zipper, the inventors of the present invention have studied to make the knitting yarn constituting the fastener chain cloth thin, but it is known that if the yarn is made thin as a whole, the required strength (especially the chain transverse tensile strength) cannot be obtained. However, the inventors of the present invention further studied and found that if two veil yarns for suturing the element rows are arranged across one warp, two stitching lines are formed, and sewing is performed across the inner side of the two stitching lines. When any one of the knitting yarns of the yarn is sufficiently thick, the strength of the utility can be obtained even if the other yarns are fine.

One aspect of the present invention based on the above findings is a zipper chain belt having a zipper tape (102) comprising a sprocket mounting portion (A) and a sprocket body portion (B), and a chain fabric (100, 200) having a warp knitting structure; and a loop-shaped resin element row (101) stitched to the element mounting portion (A); and the zipper chain is by a horizontal Two stitching lines (106) for stitching the above-mentioned element rows (101) to the element mounting portion (A) are formed across one warp ring (W2) to form two stitching lines, and across the two stitching lines One of the knitting yarns (104', 105", 112') of the knitting yarn on the inner side of the sewing thread has a fineness of 72 to 330 dTex, and the denier of all other knitting yarns is 56 to 167 dTex, wherein The one knitting yarn (104', 105", 112') of the sewing line spanning the inner side of the two sewing lines is thicker than the other substantially all knitting yarns.

Another aspect of the present invention is a zipper chain belt having a zipper tape (102) comprising a sprocket mounting portion (A) and a chain fabric body portion (B), and having a warp knitted fabric. a zipper chain cloth (100, 200); and a loop-shaped resin sprocket row (101) stitched to the sprocket mounting portion (A); and the zipper chain belt is traversed by a warp (W2) Two slit lines for stitching the element row (101) to the element attaching portion (A) to form two stitching lines, and sewing lines that straddle the inner side of the two stitching lines are disposed The knitting yarn (104', 105", 112') of the knitting yarn has a fineness of 72 to 330 dTex, and the other fineness of all the knitting yarns is 56 to 167 dTex, so that the fastener mounting portion (A) The outermost knitting yarn (103') has a fineness of 66 to 275 dTex, wherein the one knitting yarn (104', 105", 112') and the sprocket of the sewing line spanning the inner side of the two sewing threads. The outermost knit yarn (103') of the mounting portion (A) is thicker than the other substantially all knitting yarns.

In one embodiment of the fastener stringer of the present invention, the number of the number of the loops of the three knitting yarns is 50% or more of the total number of the yarn loops in one knitted loop.

In still another embodiment of the fastener stringer of the present invention, the chain cloth (100, 200) is made of crocheted knitting yarn (103, 103') and warp knitted yarn (104, 104'), and further It is woven from a total of three kinds of one of satin knitting yarns (105, 105', 105") and deformed heavy knitting yarns (112, 112').

In still another embodiment of the fastener stringer of the present invention, the one knitting yarn (104', 105", 112') of the stitching line traversing the inner side is selected from the group consisting of warp knitting yarn (104'), satin. A group of knitting yarns (105") and warp-knitted knitting yarns (112').

In still another embodiment of the fastener stringer of the present invention, the warp (W2) spanned by the two veil (106) for sewing the element rows (101) is from the outer side of the element mounting portion. The second circle.

In still another embodiment of the fastener stringer of the present invention, the veil (106) has a fineness of 100 to 350 dTex.

Still another aspect of the present invention is a zipper comprising the zipper tape (102) of the present invention.

Still another aspect of the present invention is an article sewn with the zipper of the present invention.

According to the present invention, a fastener chain having both lightness and strength is provided. Further, the zipper tape of the present invention can also obtain the effect of improving the softness by using a yarn which is thinner than the prior art.

The zipper tape of the present invention is a basic structure, and includes a fastener zipper fabric including a warp knitted fabric body and a fastener element mounting portion, and a loop-shaped resin that is sewn to the fastener element mounting portion. Chain of teeth. The reason why the fastener element row of the loop-shaped resin is used is that it is not only lighter but also has higher flexibility and higher storability, and therefore is most suitable for use as a fastener element in accordance with the object of the present invention. Examples of the resin to be the element row material include polyester, nylon, polypropylene, acrylic acid, etc., but polyester is preferred in view of good sewing property and high material strength.

Preferably, even if the knitting yarn of the woven warp knitting structure is made thin as a whole, the knitting yarn of the outermost side of the fastener element mounting portion can be sufficiently thickened while ensuring the strength which is durable as the zipper. The reason for this is that the elongation of the fastener chain cloth is suppressed, and the width dimension of the chain cloth is stabilized, so that the sewing property of the fastener elements is better. Knitting yarns having a fineness of typically 66 to 275 dTex, preferably 78 to 167 dTex can be used. As the woven structure used herein, crocheting is preferred. The reason for this is that not only the edge portion of the fastener element mounting portion but also the stretch of the warp knitting fabric can be suppressed by using the crochet, and the attachment operation of the fastener element can be easily performed.

Further, in the present invention, two sewing lines are formed by arranging two veil yarns for stitching the element rows to the element attaching portions across one of the races. The sewing line is provided with a first sewing line disposed in the vicinity of the outer side of the element attaching portion via the ring, and a second stitching line disposed on the inner side of the element attaching portion with respect to the first stitching line. The first sewing line is a sewing line on the outer side of the following, and the second sewing line is a sewing line on the inner side of the following. By installing the element rows in such a manner, it is possible to compensate for the low strength and stability of the fasteners caused by the narrowing of the knitting yarn. Considering the fact that the sprocket of the left and right zipper tapes mesh with each other, the size of the gap generated between the opposite edges of each zipper chain cloth is stabilized, and typically, two veil for suturing the sprocket row are used. The warp beam spans the second warp circle from the outer side of the element tooth mounting portion.

In view of the weight reduction of the zipper as the object of the present invention, it is preferred that the veil be a spun yarn. The spun yarn also contributes to the softness of the zipper. However, if the spun yarn is too thin, practical mounting strength and stability cannot be obtained. Therefore, it is preferable to use a yarn having a fineness of 100 to 350 dTex, and more preferably a yarn having a fineness of 110 to 250 dTex. The crochet yarn used in combination with the veil is also the same.

In the present invention, the fineness of any one of the knitting yarns of the sewing thread spanning the inner side of the two stitching lines formed in this manner is made thick. The knitting yarn of the sewing thread across the inner side means that a plurality of knitting yarns are present in the chain fabric, but only the fineness of one of the knitting yarns is made thick. Specifically, a knitting yarn having a fineness of 72 to 330 dTex, preferably 78 to 235 dTex, more preferably 78 to 167 dTex is used. By making the inner sewn thread thicker, it is possible to suppress the zipper chain cloth from being torn by the sewing line as a boundary when the force of stretching the zipper chain cloth in the width direction thereof is received. Examples of the thickened knitting yarn include a warp knitting yarn, a satin knitting yarn, and a deformed heavy knitting yarn. Further, in the present invention, the term "transformation heavy-duty knitting yarn" refers to a knitting yarn which is arranged in a zigzag shape while forming a needle loop on each of two circumferential grooves adjacent to each of the laps.

In this way, any one of the knitting yarns of the knitting yarn that straddles the inner side and the outermost knitting yarn of the sprocket mounting portion can be sufficiently thickened, and even the other substantially The fineness of the knitting yarn is finer than the knitting yarns in the range of 56 to 167 dTex, typically 66 to 110 dTex, more typically 66 to 84 dTex, and sufficient strength (especially the transverse tensile strength) can be obtained. ) The zipper. In a typical embodiment, the denier of the other substantially knit yarns differs by 10 dTex from the outermost knit yarn of the sprocket mounting portion and the slenderness of the above-mentioned thicker knit yarn across the inner sewn line. As described above, in a more typical embodiment, the difference is 20 dTex or more, for example, 10 to 40 dTex.

The above paragraphs are set to "substantially" for the following reasons. The knitted zipper fabric is designed to prevent the user from mistakenly attaching the chain main body portion and the sprocket attachment portion to the sprocket main body portion, and the main body portion of the chain fabric is centered on the left and right sides. It is a warp knitting organization that functions as a chain tooth mounting part. In such a case, it is within the scope of the present invention to have any remaining sprocket mounting portions that are not used. Further, it is intended that the use of one or two coarse knitting yarns in a portion other than the portion specified by the present invention in the form of a simple departure from the technical scope of the present invention is also within the scope of the present invention.

The chain width of the above zipper is 11 to 13 mm. The zipper is different in size depending on the purpose of use, and the size of the chain or chain cloth is different. Specifically, the wire diameter, the width dimension, the thickness dimension of the loop-shaped fastener element row, and the size of the meshing head in which the fastener element rows are engaged with each other, and the width dimension or thickness dimension of the chain cloth are different. The reason for this is that the lateral tensile strength can be improved by making the size of the element rows and the chain cloth larger. Therefore, when the size of the chain fabric is increased and the width dimension is 14 to 17 mm, it is preferable to make any one of the knitting yarns of the sewing thread spanning the inner side of the two sewing threads. The fineness of the knitting yarn is 235 to 330 dTex, and the denier of substantially all the knitting yarns other than the outermost knitting yarn of the sprocket mounting portion is 110 to 167 dTex. Further, it is preferable that the fineness of the outermost knitting yarn of the fastener element mounting portion is 167 to 275 dTex, and the fineness of the veil and the crochet yarn is 250 to 350 dTex.

Knitting yarns of the same fineness and material may be used for the element attaching portion and the chain main body portion, but the knitting yarn used in the chain main body portion and the element attaching portion may be changed. Further, regardless of the main body of the chain fabric or the element attaching portion, it is possible to change the fineness and material of each knitting yarn as needed.

As the material of the knitting yarn, polyester, nylon, polypropylene, acrylic, etc., which have been used for the zipper before, can be used, but in consideration of the use of the same material in the knitting yarn and the fastener element, the cause of the chromatic aberration after dyeing can be reduced. Preferably, it is a polyester. The knitting yarn may also comprise a monofilament or a multifilament in which two or more monofilaments are bundled. For example, a multifilament yarn obtained by bundling 50 monofilaments of 5 dTex has a fineness of 250 dTex.

The knitting yarn of the woven fastener chain cloth itself may be a well-known woven structure, and although it is not limited, for example, a woven fabric of crocheted knitting yarn, warp knitting yarn, satin knitting yarn, and deformed heavy knitting yarn can be used. However, in view of reducing the burden on the knitting machine while making the zipper chain bulky, it is preferred that the zipper chain fabric is made of crocheted knitting yarn and warp knitted yarn, and then selected from satin knitting yarn and deformation. The total of three types of heavy-knit yarns is woven. The closed or unwinding can be arbitrarily selected according to the strength required for the chain cloth.

In a preferred embodiment of the fastener stringer of the present invention, the number of the number of the yarn loops (three yarn loop knitting structures) of the three knitting yarns is 50% or more, and more preferably 60% or more. The strength, texture and bulkiness can be improved by adding three yarn loop knit structures. When the number of the two yarn loops is large, the wire is made thin, and sufficient strength, texture, and bulkiness cannot be obtained. If the number of the four yarn loops is large, the weight of the zipper as the original purpose cannot be sufficiently achieved. Further, if the knitting structure of the three yarn loops is excessively increased, the number of knitting yarns for forming the yarn loops is increased, and the weight of the zipper as the original purpose cannot be sufficiently achieved. Therefore, it is preferable that the number of laps of the three knitting yarns for one yarn loop is less than 80% of the total number of the yarn loops.

After the pair of zipper tapes are engaged to form a zipper chain, the slider and the upper and lower stops are installed to complete the zipper. The zipper of the present invention can be used as a switch member for articles by sewing to various articles, and among them, it can be preferably used for articles requiring a light lace, a cardigan, a windbreaker, and the like.

Example

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to the following embodiments, and various changes can be made within the scope of the invention.

= first embodiment =

Fig. 1 is a view showing a knitting structure of a fastener stringer (100) according to a first embodiment of the present invention. The warp knitting organization is woven using a crochet machine. The material of the knitting yarn is polyester. The zipper chain cloth (100) sequentially includes a first warp ring (W1) to a twelfth warp ring (W12) from the left end, and the first warp ring (W1) to the third warp ring (W3) form a sprocket. The attachment portion (A), the fourth warp ring (W4) to the twelfth warp ring (W12) form a chain main body portion (B).

<woven organization>

The braided structure of the zipper chain cloth (100) will be described. The sprocket mounting portion (A) and the chain main body portion (B) are crocheted knitting yarns (103, 103'), 1-0/1- which are unwrapped by 1-0/0-1 shown in Fig. 2. 2 kinds of knitted yarns of the closed-knit warp knitting yarn (104, 104') and 3-4/1-0 closed-sheet satin knitting yarn (105) are woven. Fig. 2 is a view showing the structure of each knitting yarn in the above-mentioned weave texture diagram, from the left of the figure, a thick crochet knitting yarn (103'), a crochet knitting yarn (103), a warp knitting yarn (104) , thick warp knitting yarn (104'), satin knitting yarn (deformed warp knitting yarn) (105).

In the knitting yarn of the fastener stringer of the first embodiment, the warp knitting yarn (104') spanning the second warp (W2) and the third warp (W3) and the first warp (W1) are disposed. The crocheted knitting yarn (103') is relatively thick and has a fineness of 110 dTex as the same thickness. The 10th warp ring (W10) to the 12th warp circle (W12) are also used as the element attaching portion (A), and span the 10th warp ring (W10) and the 11th warp ring (W11). The knitted yarn and the crocheted knitting yarn disposed on the twelfth warp (W12) are thick and have a fineness of 110 dTex. Other knitting yarns use a fine yarn of 78 dTex. The fineness of each knitting yarn is not limited to the above embodiment. For example, it is also possible to arrange the warp knitting yarn (104') spanning the second warp (W2) and the third warp (W3) to be the thickest 78 dTex, and to arrange it in the first warp. The crocheted knitting yarn (103') of (W1) is 72 dTex, making the other knitting yarns the finest 66 dTex compared to the knitting yarns. Further, the warp knitted yarn (104') spanning the second warp (W2) and the third warp (W3) may be placed at the first warp as compared with the knitting yarn of the third warp yarn (104'). (W1) crocheted knitting yarn (103') and other knitting yarns are 66 dTex of the same thickness.

As shown in Fig. 1, in the first embodiment, the number of the number of the yarn loops of the three knitting yarns (the three yarn loop knitting structure) of one knitting yarn is 2/3.

In the first embodiment, the weave structure of the satin knit yarn (105) spans the adjacent four warp circles. Thereby, in the example of the fastener chain cloth shown in FIG. 1, the total number of the yarn loops is 72. Among them, the number of the yarn loops (3 yarn loop knitting structures) in which one knitting yarn is interlaced with one yarn loop is 48. Therefore, the number of yarn loops of one knitting yarn for one yarn loop is about 68% of the total number of yarn loops. The weave structure of the satin knit yarn is not limited to the embodiment. For example, the weave of the satin knit yarn can also be made to traverse the adjacent three warp circles. Thereby, the number of turns of the three knitting yarns interlaced with one yarn loop is 54. Therefore, the number of turns of the three knitting yarns for one yarn loop is about 75% of the total number of yarn loops. Moreover, the weave structure of the satin knit yarn can also be made to straddle the adjacent five warp circles. Thereby, the number of turns of the three knitting yarns interlaced with one yarn loop is 42. Therefore, the number of turns of the three knitting yarns for one yarn loop is about 58% of the total number of yarn loops.

In the first embodiment, the satin knitting yarn (105) is woven by closed winding, but as shown in Fig. 4, it can be woven by a 4-3/0-1 unrolled satin knitting yarn (105'). Made. Further, the crocheted knitting yarns (103, 103') and the warp knitting yarns (104, 104') may be arbitrarily selected to be closed or unwound.

In the first embodiment, the warp knitting yarn spanning the second warp (W2) and the third warp (W3) is roving, but the first warp (W1) may be formed as shown in Fig. 5 . The satin knitting yarn (105'') having a yarn loop alternately with the fourth warp ring (W4) becomes thick. Further, although not shown, the satin knitting yarn having the yarn loops alternately between the second warp (W2) and the fifth warp (W5) may be thickened. The reason for this is that both of them straddle the second warp (W2) and the third warp (W3).

<Chain mounting>

Fig. 3 is a cross-sectional view showing a state in which the fastener element row (101) is sewn to the fastener stringer (100) to form a fastener stringer (102) in the first embodiment. There are two veil (106) configured to suture the element rows (101). Thereby, the outer sewing line is formed between the first warp (W1) and the second warp (W2), and the inner stitching line is disposed between the second warp (W2) and the third warp (W3). . Here, a sprocket row of a loop-shaped polyester is used.

The installation sequence of the chain element row (101) will be described. First, the core wire (108) is inserted through the hollow portion of the sprocket row (101), and the meshing head portion (109) of the sprocket row (101) is directed toward the outer side of the zipper chain cloth (100), and is placed on the sprocket mounting. Part (A) of the specific location. Next, the sewing needle is pierced by the groove between the groove (G1) between the first warp (W1) and the second warp (W2) and between the second warp (W2) and the third warp (W3). In the portion (G2), the two veil (106) and one crochet yarn (107) as the suture are pressed against the presser foot portion (110) and the lower presser portion (111) of the element row (101). The chain tooth row (101) and the core wire (108) are sewn to the fastener chain cloth (100). The fineness of the veil (106) and the crochet yarn (107) was 139 dTex.

<area density>

The zipper tape of the first embodiment has an areal density of 150 to 175 g/m ² and is only 60% of the weight of the original woven fastener chain.

<Strength check>

Two fastener stringers of the first embodiment were prepared, and the phases were engaged to form a fastener chain, and the transverse tensile strength was examined in accordance with JIS-S3015. As a result, the result of 557 N was obtained.

On the other hand, as a comparative example, a zipper chain of a woven fastener chain fabric having a fineness of the outermost knit yarn of the dash attachment portion of 110 dTex and other substantially all of the knitting yarns of 84 dTex was used (Comparative Example 1) ), the transverse tensile strength was checked and the result was 444 N.

According to the results, it is understood that only the fineness of one of the knitting yarns of the knitting yarn which straddles the inner side of the two sewing threads is increased, and when the transverse pulling force is applied to the fastener chain, the fastener chain can be prevented from being cracked at the sewing line. Compared with the zipper chain which is substantially thinner in all the knitting yarns, the strength is remarkably increased, so that the strength of the previous zipper chain which is thicker than all the knitting yarns can be obtained.

= second embodiment =

Fig. 6 is a view showing a portion of a knitting structure of a fastener stringer (200) according to a second embodiment of the present invention. The warp knitting organization is woven using a crochet machine. The zipper chain cloth (200) has a woven structure in which a satin knitting yarn is changed to a 3-4/1-0 deformation heavy warp knitting yarn with respect to the first embodiment. Therefore, the fastener stringer (200) of the second embodiment is composed of three types of knitting yarns of crocheted knitting yarns (103, 103'), warp knitting yarns (104, 104') and deformed heavy knitting yarns (112). Braided. Fig. 7 is a view showing the structure of each knitting yarn in the above-mentioned knitting structure diagram, from the left of the figure, a thick crochet knitting yarn (103'), a crochet knitting yarn (103), and a warp knitting yarn (104). , thick warp knitting yarn (104'), deformation heavy knitting yarn (112).

In the second embodiment, the number of the yarn loops (3 yarn loop knitting structures) in which one knitting yarn is interlaced with one yarn loop is 7/12 of the total number of yarn loops.

In the second embodiment, the crocheted knitting yarns (103, 103') are woven by unwinding, and the warp knitting yarns (104, 104') are woven by closed winding, but can be closed or unwound. Free to choose.

In the second embodiment, the warp knitting yarn (104') spanning the second warp (W2) and the third warp (W3) is roving, but as shown in FIG. 1 The warp-knitted yarn (112') is thickened by the warp (W1) to the fourth warp (W4). Further, although not shown, the deformation of the second warp (W2) to the fifth warp (W5) may be made thicker than the knitting yarn. The reason for this is that both of them straddle the second warp (W2) and the third warp (W3).

In the case of using the woven fastener stringer of the second embodiment, as in the first embodiment, a zipper chain which is lightweight and excellent in strength can be obtained.
