Description

Zipper chain and zipper chain

The present invention relates to a zipper chain cloth and a zipper chain belt for a zipper, and more particularly to a zipper chain cloth and a zipper chain belt having improved structure of a core portion disposed along a side edge of the chain cloth.

A zipper having a plurality of metal fastener elements is often used for, for example, a body or an opening portion of a fine twill fabric. A zipper having such a metal fastener element is manufactured by a method in which a plurality of metal fastener elements are attached at a predetermined interval by a side edge portion of a pair of left and right fastener chains. A pair of zipper tapes are further slidably mounted on the sprocket rows of the pair of zipper tapes obtained by a plurality of zipper elements.

Further, a belt-shaped fastener chain cloth for attaching metal fastener elements has a chain cloth body which is woven by weft yarns and warp yarns, and a bulged core portion (also referred to as a core rope portion). In other words, it is disposed along one side edge of the chain body, and is swelled in the front and back directions of the chain cloth with respect to the front and back sides of the chain fabric (the first chain cloth surface and the second chain cloth surface).

In the case where the metal zipper element is attached to the zipper chain cloth, first, in the state in which one of the open zipper elements is in the state of the foot, the sprocket including the core of the zipper chain cloth is inserted between the two leg portions. unit. Then, the fastener element is inserted into the fastener chain in a specific posture by fastening the leg of the fastener element. The zipper tape is manufactured by performing such an implantation step on each of the fastener elements.

Such a zipper chain cloth with a core cord for inserting a metal zipper element, for example, Japanese Patent Publication No. Sho 59-25215 (Patent Document 1), or Chinese Utility Model Publication No. 201123458 (Patent Document 2), and the like.

As shown in FIG. 15 , for example, the fastener chain cloth 70 described in Patent Document 1 includes a chain body 71 that is woven by weft and warp yarns, and a core portion 72 that is disposed along one side edge of the chain body 71 . The core portion 72 of the fastener chain cloth 70 includes a bag-woven portion 73 woven along one side edge of the chain body 71 and a core yarn 74 woven into the bag-woven portion 73.

In particular, the core cord 74 of Patent Document 1 is formed by enclosing a core wire 75 including a plurality of multifilament yarns of a yam by braiding a plurality of knitting yarns into a peripheral knitting layer 76. Such a core cord 74 also has a condition called a braided cord.

The core portion 72 is formed by weaving the core rope (woven rope) 74 into the bag-woven portion 73, so that the core rope 74 and the bag-woven portion 73 are moderately softened and firmly integrated, thereby preventing the position of the core rope 74. Offset. Therefore, by attaching the metal zipper element to the element attaching portion of the zipper chain 70 including the core portion 72, the zipper element is securely fastened and fixed, and the mounting pitch of the zipper element is less likely to be loose. .

Further, as shown in FIG. 16, the fastener chain cloth 80 described in Patent Document 2 has a chain main body 81 which is woven by weft and warp yarns, and a core portion 82 which is disposed along one side edge of the chain main body 81. The core portion 82 of the fastener stringer 80 is formed by weaving the weft yarns constituting the chain main body 81 in a state in which a plurality of filaments are only conjugated. In particular, the core portion 82 of Patent Document 2 is formed by weaving in a state in which the upper surface side core portion of the chain fabric is formed by holding 10 or more filaments by the weft yarn, and more than 10 pieces are provided. The lower side core portion of the chain cloth formed by the filaments and the yarn.

In the zipper chain cloth 80 of the above-mentioned Patent Document 2, the core portion 82 is formed so as not to include the core wire in the outer peripheral woven layer, for example, in the patent document 1, so that the processing steps of the processing core rope or the core rope can be reduced. Weaving machine for outer peripheral braid. Therefore, in Patent Document 2, the processing efficiency of the fastener chain cloth 80 is improved, and the equipment cost is also reduced, so that the manufacturing cost of the zipper can be greatly reduced.

On the other hand, for example, Japanese Laid-Open Patent Publication No. Hei 7-79815 (Patent Document 3) discloses a zipper chain fabric in which a weft yarn and a warp yarn are woven, and a core portion is disposed along one side edge of the chain body. . Further, the zipper chain cloth of Patent Document 3 is not formed by attaching a metal fastener element to a fastener stringer as in the above-described Patent Documents 1 and 2, and is formed by sewing. The step is to form a fastener string by sewing a plurality of synthetic resin fastener elements which are connected to each other by a connecting yarn.

Specifically, as shown in FIG. 17, the fastener stringer 90 of the patent document 3 has the chain body 91 woven by the weft and the warp, and the core part 92 arrange|positioned along the side edge of the chain body 91. The core portion 92 of the fastener chain fabric 90 has a pocket portion 93 woven along one side edge of the chain body 91, and a plurality of core wires 94 having the same thickness as the warp yarn of the chain cloth body 91, and a plurality of core wires 94 are attached. The bag weaving portion 93 is woven into a state in which it is arranged in parallel.

According to Patent Document 3, since the core portion 92 of the fastener stringer 90 described above has resilience, resilience, and flexibility, the core portion 92 is crushed when the synthetic resin fastener element is attached to the fastener chain cloth 90. Therefore, a zipper with a strong mounting strength and a thin thickness of the zipper element is obtained.

[Patent Document 3] Japanese Patent Laid-Open No. Hei 7-79815

In the fastener stringer 70 of Patent Document 1, as shown in FIG. 15, a core rope (woven rope) 74 formed by enclosing a core wire 75 including a plurality of multifilaments by a peripheral knitting layer 76 is woven into the bag weave portion 73. Thereby, the core portion 72 having both appropriate hardness and flexibility is formed. Therefore, the metal fastener can be firmly and firmly fixed to the fastener element mounting portion of the zipper chain 70 including the core portion 72. Chain teeth.

Moreover, since the core portion 72 is not easily crushed when the fastener element is attached to the element attaching portion, the mounting posture of the fastener element can be stably maintained, and the position of the attached fastener element can be prevented from being easily oriented in the longitudinal direction of the chain. Offset. Therefore, the strength (sliding strength) of the state in which the fastener element is attached is maintained when the fastener element is subjected to the force in the longitudinal direction of the fastener.

However, the zipper chain cloth 70 of Patent Document 1 requires a dedicated device or step for manufacturing the core rope 74 as a braided rope. Therefore, it is difficult to reduce the equipment cost or increase the manufacturing efficiency, resulting in an increase in the manufacturing cost of the zipper.

In the zipper chain cloth 80 of Patent Document 2 shown in Fig. 16, the bulged core portion 82 does not use the woven rope as in Patent Document 1, but is woven together with only the plurality of warp yarns (multifilament yarns) and the weft yarns. It is formed in, so as described above, the manufacturing cost of the zipper can be reduced.

However, in the fastener stringer 80 of Patent Document 2, since the plurality of warp yarns forming the core portion 82 are held only by the weft yarn, the strength of the core portion 82 is weak. Therefore, when the metal fastener element is attached by the fastening process in the fastener element mounting part of the zipper chain cloth 80 including the core part 82, the position of the warp yarn is shifted by the pressing of the fastener element, and the core part is shifted. 82 is prone to deformation such as flattening.

Therefore, when the fastener element 80 is fastened to the fastener element, for example, the core portion 82 protrudes from the two leg portions of the fastener element to hinder the plastic deformation of the foot portion, thereby reducing the mounting strength of the fastener element. , or the occurrence of a problem such as tilting of the mounting position of the zipper element.

Further, even if the fastener element is attached without the core portion 82 being extended, there is a problem in that the core portion 82 is easily deformed, so that the position or posture of the fastener element is unstable, and the fastener element is caused to be zippered. The sliding strength is lowered, and the like.

On the other hand, in the fastener stringer 90 of Patent Document 3 shown in FIG. 17, since the core portion 92 is formed without using the braided cord of Patent Document 1, the cost of the slide fastener can be reduced. However, in the case of the patent document 3, the core wire 94 is wrapped in the bag-yarn portion 93 in a state of being easily moved to form the core portion 92. Therefore, for example, in the case of Patent Document 2, only the weft yarn is held in plural. The deformation of the core portion 92 is less likely to occur than in the case of the root warp yarn, but the position of the warp yarn held in the bag-woven portion 93 is easily offset from the core yarn 74 of the braided rope of Patent Document 1, for example.

Therefore, when the metal fastener stringer is attached by the fastening process of the fastener stringer 90 of the patent document 3, it is feared that the core part 92 protrudes from the both leg parts of the fastener element, and the plasticity of the foot is hindered. Deformation, or failure to reduce the mounting strength or sliding strength of the fastener elements.

The present invention has been made in view of the above-described problems, and a specific object thereof is to provide a fastener chain cloth and a fastener stringer in which a metal fastener element is attached to the fastener chain cloth, and the fastener chain cloth does not use a braided rope. When the core fastener is formed and the metal fastener element is attached by fastening, the plastic deformation of the fastener element is prevented from being hindered, and the fastener element can be stably attached in a specific posture, and the fastener element can be sufficiently obtained. Installation strength or sliding strength.

In order to achieve the above object, the most important feature of the zipper chain cloth provided by the present invention is that, as a basic structure, there is a chain body and a core disposed along a side edge of the chain body, and the chain cloth system The weft yarn is woven by a warp yarn and a plurality of warp yarns including a multifilament yarn, and the core portion is provided with a bag weave portion obtained by using the weft yarn and a plurality of bag warp yarns including the multifilament yarn, and inserted into the bag weaving portion. a core wire comprising a multifilament yarn; and at least a portion of the warp yarns of the warp yarns have a total fineness greater than a total fineness of the warp yarns of the chain fabric body, and a single denier of each filament constituting the warp yarns is set to be larger than the chain The single denier of each filament of the warp body of the cloth.

In particular, in the zipper chain cloth of the present invention, preferably, the bag warp yarn comprises: a pair of upper and lower body side warp yarns, which are adjacent to the chain cloth body; and a pair of upper and lower side or one side edge warp yarns, etc. The main body side warp yarn is disposed at a side edge position of the chain fabric on the opposite side of the bag fabric portion in the width direction of the chain fabric, and the plurality of first intermediate warp yarns are disposed between the main body side warp yarn and the side edge warp yarn. Chain cloth side; and plural root 2nd middle a yarn, which is disposed on a second chain surface side opposite to the first chain cloth surface between the main body side warp yarn and the side edge warp yarn; and the total fineness of each of the first and second intermediate warp yarns is set to be larger than The total fineness of the warp yarns of the chain fabric body is such that the single fineness of each of the filaments constituting each of the first and second intermediate warp yarns is set to be larger than the single fineness of each of the filaments constituting the warp yarn of the chain fabric body.

In the zipper chain cloth of the present invention, it is preferable that the number of the thickness per unit of the filaments constituting each of the first and second intermediate warp yarns is set to be larger than the thickness per unit of the filament constituting the warp yarn of the chain fabric body. The number of roots is small.

Further, it is preferable that the number of filaments in each of the first and second intermediate warp yarns is set to be 24 or more and 29 or less per 167 dtex.

Further, in the fastener stringer of the present invention, preferably, the total fineness of the main body side warp yarn and the side edge warp yarn is set to be smaller than the total fineness of the first and second intermediate warp yarns.

Further, in the fastener stringer of the present invention, preferably, the total fineness of the first and second intermediate warp yarns adjacent to the side edge warp yarns is set to be larger than the total fineness of the other first and second intermediate warp yarns. Alternatively, the total fineness of the first and second intermediate warp yarns adjacent to the side edge warp yarns and the total fineness of the first and second intermediate warp yarns adjacent to the main body side warp yarns may be set to be larger than the other first The total fineness of the second intermediate warp yarn.

Further, in the fastener stringer of the present invention, it is preferable that the number of the first intermediate warp yarns and the number of the second intermediate warp yarns are four or more and nine or less.

In the fastener stringer of the present invention, preferably, the chain fabric body has a core adjacent single-layer woven portion woven by a single-layer woven structure adjacent to the core portion, and the core adjacent single-layer woven portion has the above The first to fourth chain main body warp yarns are sequentially woven by the core side by 2/2, and the first chain main body warp yarn and the second chain main body warp yarn are arranged to warp the 2/2 in the warp direction. The third chain fabric main warp yarn and the fourth chain fabric main warp yarn are woven by shifting the 2/2 tissues in the warp direction by two tissue points, and the first one is woven. And the second chain fabric main warp yarn and the third and fourth chain fabric main warp yarns are woven by shifting the 2/2 tissue in the warp direction by one tissue point.

Further, the most important feature of the zipper tape provided by the present invention is that it is attached to a sprocket mounting portion including the core portion of the zipper chain cloth having the above-described configuration, and a plurality of metal zipper fastener elements are mounted at a specific pitch. to make.

The zipper chain cloth of the present invention has a chain fabric body which is woven by a warp yarn and a plurality of warp yarns including a multifilament yarn, and a core portion which is disposed along one side edge of the chain fabric body, and the core portion is provided A bag weave portion obtained by weaving the weft yarn and the plurality of bag warp yarns including the multifilament yarn, and a core wire containing the multifilament yarn held in the bag weave portion.

Further, at least a portion of the warp yarns of the plurality of bag warp yarns have a total fineness greater than a total fineness of the warp body warp yarns. Further, the single fineness of each of the filaments constituting the bag warp yarn having a total fineness larger than the warp of the main body of the chain fabric is set to be larger than the single fineness of each of the filaments constituting the warp of the main body of the chain fabric.

According to the zipper chain cloth of the present invention, the bulged core portion is woven into the woven portion of the woven fabric which is woven by the weft yarn and the plurality of woven warp yarns, and the woven fabric includes the filaments arranged in parallel along the warp yarn direction. The core of the yarn is formed without using the braided rope of Patent Document 1 described above. Therefore, it is possible to reduce the manufacturing cost without the need to manufacture a special device or step for braiding the rope.

Further, in the present invention, at least a part of the plurality of bag warp yarns has warp yarns having a larger total fineness than the warp body warp yarns, whereby the metal fastener elements are attached to the fastener chain cloth by, for example, fastening processing. When the warp yarns with a large total fineness are mutually supported, the positions of the warp yarns of the respective bags are not easily offset, and the core wires held in the bag weaving portions are supported by the coarse warp knit yarns, so that the positions of the filaments of the core wires are not easily biased. shift.

Further, in the present invention, since the bag warp yarns having a large total fineness are formed using thicker filaments, the hardness or strength of the core portion (bag portion) can be improved. Therefore, in the present invention, compared with the fastener chain cloth described in the above-mentioned Patent Document 2 or Patent Document 3, it is possible to suppress the core portion from being crushed, the width of the core portion is increased, and it is easy to maintain the chain of the core portion. The dimension in the forward direction (height size).

Therefore, when the metal fastener element is attached by the fastening process in the fastener element mounting part of the core part of the fastener stringer of this invention, even if a core part is pressed by a fastener element, it can suppress an excessive crushing. Or expand in the direction of the chain width. Therefore, for example, when the fastener element which is fastened by the core is pressed, the inner peripheral side space of the leg portion of the fastener element protrudes toward the chain main body side, thereby preventing the leg portion from interfering with the fastener element. Bad conditions such as plastic deformation.

Further, in the present invention, since the core portion is hard and is not easily crushed in the front-back direction of the chain cloth, the fastener element can be firmly and stably fixed to a specific position of the fastener chain cloth in a specific posture. Therefore, the mounting strength of the fastener element with respect to the fastener chain can be effectively improved. Further, the mounting state of the fastener element attached to the fastener element of the fastener stringer can be stably maintained, and the sliding strength of the fastener element with respect to the longitudinal direction of the fastener can be effectively improved.

In particular, in the present invention, the bag warp yarn forming the bag weave has: a pair of upper and lower body side warp yarns, which are adjacent to the chain cloth body; a pair of upper and lower side or one side edge warp yarns, which are arranged on the side edges of the chain cloth a plurality of first intermediate warp yarns disposed on the first chain fabric side between the main body side warp yarns and the side edge warp yarns, and a plurality of second intermediate warp yarns disposed on the body side warp yarns and the side edges The first chain cloth surface between the warp yarns is opposite to the second chain cloth surface side via the core wire. Further, each of the first and second intermediate warp yarns disposed in the bag fabric portion has a total fineness larger than that of the warp body body disposed on the chain fabric main body, and is formed thicker than the warp body main warp yarn. Further, each of the filaments constituting each of the first and second intermediate warp yarns has a single fineness (also referred to as a single fiber fineness) which is larger than the filaments constituting the warp yarn of the main body of the chain fabric, and is formed to be thicker than the warp yarn of the chain fabric body. .

In this manner, the metal fastener elements are attached by fastening processing by using the body side warp yarns and the side edge warp yarns, and the first and second intermediate warp yarns having a larger total fineness than the warp body warp yarns. In the case of the zipper chain cloth, the first intermediate warp yarns having a larger total fineness support each other or the second intermediate warp yarns support each other to position the first and second intermediate warp yarns. The core wire held in the weave portion is supported by the relatively thick first and second intermediate warp yarns, so that the position of the filaments of the core wire is not easily displaced.

Further, in the present invention, by forming the first and second intermediate warp yarns using the thicker filaments, the hardness or strength of the core portion (bag portion) can be effectively increased, so that the fastener chain is as described above. When the metal fastener stringer is attached by the fastening process, the core can be prevented from being excessively crushed or expanded in the width direction of the chain even when pressed by the fastener element, so that the fastener element can be positioned in a specific posture. Firmly and stably fixed to a specific position of the zipper chain cloth.

In the fastener stringer of the present invention, the number of the thickness per unit of the filaments constituting each of the first and second intermediate warp yarns (for example, the number per 167 dtex) is set to be longer than the filament constituting the warp of the main body of the chain fabric. The number of roots per unit thickness is small.

For example, the number of filaments constituting the warp yarn of the main body of the chain fabric is usually set to 36 or more per 167 dtex, whereas the number of filaments in each of the first and second intermediate warp yarns of the present invention is set to be 167dtex is 24 or more and 29 or less. By setting the number of the filaments constituting the first and second intermediate warp yarns to 24 or more per 167 dtex, the first and second intermediate warp yarns having the desired strength can be stably produced. Further, by making the number of filaments constituting the first and second intermediate warp yarns less than 29, the core portion can be formed more firmly, and the core portion is less likely to be deformed.

Further, in the fastener stringer of the present invention, the main body side warp yarns and the side edge warp yarns disposed at both end portions in the width direction of the chain fabric in the bag fabric portion have a smaller total fineness than the first and second intermediate warp yarns, and preferably The body side warp yarns and the side edge warp yarns have the same total denier as the warp body body warp yarns. Thereby, it is possible to further suppress the expansion of the core portion in the width direction, so that the ratio of the width dimension of the core portion to the height dimension can be suppressed to be relatively small. Therefore, it is possible to more effectively prevent the core from projecting from the inner peripheral side space of the leg portion of the fastener element attached to the fastener stringer, so that the fastener element can be stably plastically deformed.

Further, in the fastener stringer of the present invention, adjacent to the first and second sides of the side edge warp yarn The warp yarns are formed thicker than the total fineness of the other first and second weave forming warp yarns. Thereby, even if the core portion is pressed from the fastener element, the position of the first and second intermediate warp yarns or the position of the core wire can be made less likely to be shifted toward the side edge side of the chain fabric, thereby suppressing the core portion to the side edge of the chain fabric. Side deformation.

Further, in the present invention, the first and second intermediate warp yarns adjacent to the side edge warp yarns and the first and second intermediate warp yarns adjacent to the main body side warp yarn may have larger warp yarns than the other first and second warp yarns. The total fineness is formed to be thicker. Thereby, even if the core portion is pressed from the fastener element, the position of the first and second intermediate warp yarns or the position of the core wire can be made less likely to be shifted toward the side edge side of the fastener fabric or the main body of the chain fabric, thereby suppressing the core portion. It is deformed toward the side edge side of the chain cloth or the side of the chain cloth body.

Moreover, in the fastener stringer of the present invention, the number of the first intermediate warp yarns and the number of the second intermediate warp yarns are each set to be the same number of four or more and nine or less. By setting the number of the first and second intermediate warp yarns to four or more, the core portion can be formed large, and the height of the core portion can be ensured to be large. Therefore, the fastener element can be stably fixed around the core of the fastener chain when the fastener element is attached. Further, the first and second intermediate warp yarns can be densely arranged in the bag-woven portion, and the first and second intermediate warp yarns can be prevented from being displaced in the warp direction, whereby the core portion can be stably formed. On the other hand, by setting the number of the first and second intermediate warp yarns to 9 or less, it is possible to prevent the width dimension of the core portion from becoming excessively large, and it is possible to more effectively prevent the core portion from being attached to the zipper of the fastener chain cloth. The inner peripheral side space of the leg portion of the sprocket extends.

Further, in the fastener stringer of the present invention, the chain fabric body has an adjacent single-layer woven portion woven by a single-layer woven structure adjacent to the core portion, and the adjacent single-layer woven portion has a sequence from the core side to 2 /2 tissue weaving of the first to fourth chain body warp yarns. Further, in this case, the first chain fabric main warp yarn and the second chain fabric main warp yarn are woven by moving the 2/2 tissue in the warp direction by two tissue dots, and the third chain fabric main warp yarn and the fourth chain. The cloth body warp yarns are woven by 2/2 tissues which are staggered by two tissue points in the warp direction. Further, the first and second chain main body warp yarns and the third and fourth chain main body warp yarns are arranged so that the 2/2 tissues are shifted from each other in the warp direction. Organize and weave. By having such a contiguous single-layer woven portion, the structure of the woven portion of the core portion can be made more stable, and the shape of the woven portion can be stably maintained, so that the zipper element can be implanted more stably and smoothly.

Moreover, according to the present invention, there is provided a fastener stringer which is obtained by attaching a plurality of metal fastener elements at a specific pitch to a fastener element including a core portion of the fastener stringer having the above-described configuration. According to the fastener stringer of the present invention, the core portion is formed without using the braided cord of Patent Document 1, and the fastener element is firmly and stably fixed in a specific posture in the fastener attached portion including the core portion. Therefore, it is possible to reduce the manufacturing cost of the zipper, and it is possible to manufacture a high-quality zipper having a high mounting strength or sliding strength of the fastener element and excellent operability or slidability of the slider.

Each of the left and right fastener stringers 10 in the first embodiment is formed by attaching a plurality of metal fastener elements 14 at a specific distance between the opposite side edge portions (the fastener attachment portions 22) of the fastener chain 20 . Further, in the front end portion and the rear end portion of the fastener stringer 20, a reinforcing film formed by attaching a synthetic resin film to the upper surface of the fastener fabric (the first chain fabric surface) and the lower surface of the fastener fabric (the second chain fabric surface) is formed. Part 15.

In this case, each of the fastener elements 14 has the same configuration as the metal fastener elements previously used. Specifically, the fastener element 14 of the first embodiment is manufactured by cutting a metal wire having a substantially Y-shaped cross section called Y bar (Y bar) at a specific thickness to form a fastener element. The formed element material is subjected to press working or the like to form the meshing head portion 14a.

The main body portion 14b and the main body portion 14b are branched into two strands and one pair of legs is extended. Part 14c. In this case, the pair of leg portions 14c are opened to form the inner peripheral side space 14d in the inner region of the front end of the leg portion to the leg portion 14c, and the inner peripheral surface portion of the leg portion 14c facing the inner peripheral side space 14d is observed. The cross section orthogonal to the longitudinal direction of the chain fabric is formed in a substantially arc shape.

Further, the substantially Y-shaped fastener element 14 shown in FIG. 7 is in a state in which the following core portion 24 of the fastener tape 20 is inserted into the inner peripheral side space 14d formed between the pair of leg portions 14c. The fastener element 14 is fastened so that the two leg portions 14c approach each other, and the leg portions 14c are plastically deformed in the inward direction.

Thereby, the fastener element 14 is formed by pressing the core portion 24 into and holding the inner peripheral side space 14d, and sandwiching the chain body 23 of the fastener chain 20 between the ends of the two leg portions 14c. Attached to the element attaching portion 22 of the fastener chain cloth 20 (see Fig. 8).

In this case, as shown in FIG. 2, the maximum value of the dimension in the width direction of the fastener attached to the fastener element 14 of the fastener stringer 20 is defined as the total length E of the fastener element. Further, the width dimension of the left and right fastener elements 14 in the engaged state is defined as the chain width C.

Each of the left and right fastener tapes 20 in the first embodiment has a chain main body portion 21 that is sewn to a zipper-attached product (clothes, bags, etc.), and a fastener element mounting portion 22 to which the fastener elements 14 are attached. Further, each of the fastener chain fabrics 20 of the first embodiment has a chain main body 23 which is disposed across the chain main body portion 21 and the element attaching portion 22, and the upper surface of the chain cloth (the first chain cloth surface) and The lower surface of the chain fabric (the second chain cloth surface) is formed to be substantially flat; and the core portion 24 is disposed along the side edge of the chain cloth opposite to the fastener stringer 10 of the meshing target, and is provided with respect to the chain body 23 The shape of the chain cloth is bulging in the direction of the back.

The chain main body 23 in the fastener stringer 20 of the first embodiment is woven by using the weft yarn 40 of the double yarn including the multifilament yarn and the plurality of chain fabric main warp yarns 41 including the multifilament yarn. As shown in FIG. 4, the woven fabric of the chain body 23 is arranged in a 1/1 configuration in which the warp yarns 41 are alternately moved on the upper side and the lower side of the weft yarn 40, and the warp yarns 41 and the weft yarns are used as the chain body. 40 flat woven tissue formed by floating and sinking.

Furthermore, in the present invention, the fabric structure of the chain body 23 is not limited, for example, As in the second embodiment, a part or all of the structure of the warp yarn warp yarn 41 can be woven into a chain fabric body 23 from 1/1 to 2/2. Further, as in the third embodiment described below, part of the warp yarn warp 41 may be changed from 1/1 to 1/3, 3/1 (or 1/4, 4/1), and formed in part. The double weave is woven into a chain body 23. Further, in the present invention, the chain main body warp yarn 41 of the chain fabric main body 23 is disposed at least adjacent to the bag-like portion 25 of the core portion 24, and is disposed on the side of the most woven fabric portion 25 The position of the chain body warp yarn 41) must be woven in a single layer of weave.

The weft yarn 40 of the first embodiment is formed by combining two single yarns and a plurality of yarns. In this case, the single yarn of the weft yarn 40 is a polyester fiber having a total fineness of 160 dtex or more and 510 dtex or less, and a fineness (single fineness) per filament of 2.7 dtex/f or more and 10.0 dtex/f or less. In particular, in the case of the first embodiment, the total fineness of each single yarn of the weft yarn 40 was 330 dtex, and the single fineness was set to 6.3 dtex/f. Further, in the present invention, the total fineness and the single fineness of the weft yarn 40 are not particularly limited and may be arbitrarily changed.

Each of the chain main warp yarns 41 forming the chain main body 23 of the first embodiment has a total fineness of 160 dtex or more and 340 dtex or less, and a single fineness of 2.7 dtex/f or more and 5.6 dtex/f or less, preferably 3.2 dtex/f. Above and below 5.3dtex/f polyester fiber.

Further, the number of 167 dtex of the filaments forming the warp yarns 41 of each of the chain fabric bodies is 30 or more and 60 or less, preferably 36 or more and 52 or less. Further, the diameter of each filament is set to be 15.0 μm or more and 22.9 μm or less, preferably 18.0 μm or more and 20.0 μm or less.

In particular, in the case of the first embodiment, the total fineness of the warp yarns 41 of each of the chain fabric bodies is set to 167 dtex, and the number of filaments forming the warp yarns 41 of each of the chain fabric bodies is set as shown in Fig. 5 (per 167dtex) 52 pieces (in this case, the single fineness of the warp body warp yarn 41 becomes 3.2 dtex/f).

The core portion 24 of the fastener chain cloth 20 of the first embodiment is as shown in Figs. 3 and 4, and the double weave is woven by using the weft yarn 40 and the plurality of bag warp yarns including the multifilament yarn. The core fabric 26 is inserted and held in the woven bag fabric portion 25.

In this case, the core wire 26 is held in the bag-woven portion 25 in a state in which a plurality of filaments are arranged in parallel, and is not provided, for example, by knitting a plurality of knitting yarns into a peripheral knitting layer as in Patent Document 1 described above. It is composed of a braided rope. Further, the core wire 26 of the first embodiment is constituted by a multifilament yarn made of polyester having a total fineness of 2,338 dtex. Further, in the present invention, the total fineness and the single fineness of the core wire 26 or the number of the filaments forming the core wire 26 are not particularly limited and may be arbitrarily changed.

The bag warp yarn forming the bag weaning portion 25 of the first embodiment has a pair of upper and lower body side warp yarns 43, which are arranged adjacent to the chain cloth body 23 in a 1/3, 3/1 configuration; a pair of upper and lower side edge warp yarns 44 It is disposed at a position on the side edge side of the chain cloth in the width direction of the chain fabric in a 1/3 or 3/1 structure (in other words, the side of the body side warp yarn 43 on the opposite side of the bag fabric portion 25 in the chain width direction). The position of the side edge of the chain cloth or the position farthest from the chain body 23 in the width direction of the chain fabric; and the five first intermediate warp yarns 45 are disposed between the body side warp yarns 43 and the side edge warp yarns 44, and form a chain. a bag-weaving chain portion on the cloth upper surface (first chain cloth surface) side; and five second intermediate warp yarns 46 disposed between the main body side warp yarns 43 and the side edge warp yarns 44, and forming a lower surface of the chain cloth (second The bag fabric portion on the side of the chain fabric surface; and 14 bag warp yarns are arranged in total in the bag fabric portion 25. Furthermore, in the present invention, the first intermediate warp yarns 45 and the second intermediate warp yarns 46 are disposed on the bag-woven portion 25 in the same number.

Each of the main body side warp yarns 43 of the first embodiment is a polyester multifilament yarn. The total fineness and the single fineness of the main body side warp yarns 43 and the number of the filaments forming the main body side warp yarns 43 are not particularly limited in the present invention, but the width of the core portion 24 is suppressed to be small to prevent it. The base side warp yarns 43 are preferably formed of polyester fibers which are thinner than the first and second intermediate warp yarns 45, 46 (total fineness).

For example, the main body side warp yarn 43 preferably has a total fineness of 160 dtex or more and 340 dtex or less, and the single fineness is set to 2.7 dtex/f or more and 5.6 dtex/f or less (especially 3.2 dtex/f or more and 5.3 dtex/f or less). And, again, each of the filaments forming the body side warp yarn 43 The number of dtex is 30 or more and 60 or less (especially 36 or more and 52 or less), and the diameter of each filament is set to 15.0 μm or more and 22.9 μm or less (especially 18.0 μm or more and 20.0 μm or less).

In particular, the main body side warp yarn 43 in the first embodiment uses the same polyester fiber as the chain main body warp yarn 41 of the chain body 23, whereby the width dimension of the core portion 24 is suppressed from becoming large. Further, in the present invention, the pair of upper and lower body side warp yarns 43 can also be woven in 1/4, 4/1.

Each of the side edge warp yarns 44 of the first embodiment is a multifilament yarn of nylon (for example, nylon 66). The total fineness and the single fineness in the side edge warp yarns 44 and the number of the filaments forming the main body side warp yarns 43 are not particularly limited in the present invention, but are prevented in order to suppress the width dimension of the core portion 24 to be small. It extends between the leg portions 14c of the fastener elements 14, while the side edge warp yarns 44 use relatively thin fibers.

For example, the side warp yarns 44 preferably have a total fineness of 160 dtex or more and 340 dtex or less, and a single fineness of 2.7 dtex/f or more and 5.9 dtex/f or less (especially 3.2 dtex/f or more and 5.1 dtex/f or less). Further, the number of 167 dtex of the filaments forming the side edge warp yarns 44 is 30 or more and 60 or less (especially 36 or more and 52 or less), and the diameter of each filament is set to be 15.0 μm or more and 22.9 μm. The following (especially 18.0 μm or more and 20.0 μm or less).

In particular, the side edge warp yarns 44 of the present embodiment 1 have the same total fineness of 167 dtex as the chain fabric warp yarns 41 or the side edge warp yarns 44 of the chain fabric body 23, and form the roots of the filaments of the side edge warp yarns 44. The number becomes 52 nylon fibers. Thus, the zipper chain cloth 20 can be produced by using a nylon fiber which is more heat-shrinkable than the polyester fiber as the side edge warp yarn 44, and after the zipper chain cloth 20 is woven and then subjected to heat curing treatment or dyeing treatment. The core portion 24 has a concave shape on the inner side in the lateral direction, and the side wall side edge side opposite to the core portion 24 side has a convex shape.

For example, in the case where a metal fastener stringer is attached to a fastener chain cloth, a tension of a specific size is usually applied to the fastener chain cloth along the longitudinal direction of the chain fabric, so that the fastener chain cloth is used. In the state of elongation, a plurality of zipper elements are implanted by fastening processing. Therefore, after the tension applied to the fastener element is released after the step of implanting the fastener element, the stretched portion of the fastener element is easily maintained at the fixed portion of the fastener element, so that the fastener is attached to the fastener element. The side edge portion of the chain fabric on the opposite side of the core side is less likely to recover. As a result, there is a case where the fastener stringer is bent such that the element attaching portion is convex, and a problem that the zipper is formed into a wavy wrinkle is called a creping.

On the other hand, as in the first embodiment, the nylon fiber is used as the side edge warp yarn 44, and the zipper chain cloth 20 is biased before the implantation step of the fastener element 14 to thereby align the zipper chain 20 When the tension fastener is attached and a plurality of metal fastener elements 14 are attached by fastening processing, the degree of recovery of the elongation between the left and right side edges of the fastener chain cloth 20 can be absorbed. The resulting zipper tape 10 is less prone to the problem of creping as described above.

Further, in the present invention, the pair of upper and lower body side warp yarns 43 can also be woven in 1/4, 4/1. Furthermore, in the present invention, the number of the main body side warp yarns 43 disposed at the position on the side edge side of the chain fabric in the width direction of the chain fabric may be one, and is not set to two as in the first embodiment. Thereby, the bag weave portion 25 is formed.

The five first intermediate warp yarns 45 and the five second intermediate warp yarns 46 disposed between the main body side warp yarns 43 and the side edge warp yarns 44 have a total fineness and a single fineness which are larger than the warp body warp yarns 41, and further constitute the present embodiment. The number of 167 dtex of the filaments of each of the first and second intermediate warp yarns 45, 46 of Example 1 is set to be smaller than the number of 167 dtex of the filaments forming the warp yarn 41 of the chain fabric.

Specifically, the total fineness of each of the first and second intermediate warp yarns 45, 46 in the first embodiment is larger than the total fineness of the warp yarn 41 of the main body of the chain fabric, and is set to be 330 dtex or more and 1010 dtex or less. Further, the single fineness of each of the first and second intermediate warp yarns 45 and 46 is larger than the single fineness of the warp yarn 41 of the main body of the chain fabric, and is set to be 5.7 dtex/f or more and 7.0 dtex/f or less.

Further, the number of 167 dtex of the filaments forming the first and second intermediate warp yarns 45 and 46 is 24 or more and 29 or less, and the diameter of each filament is set to be 23.0 μm or more and 25.3 μm or less. A multifilament yarn having such a thickness has a case called a low count yarn.

Further, in the first embodiment, the first and second intermediate warp yarns 45 and 46 disposed adjacent to the side edge warp yarns 44 are formed thicker than the other first and second intermediate warp yarns 45 and 46. Specifically, the total fineness of the first and second intermediate warp yarns 45, 46 adjacent to the side edge warp yarns 44 is set to 1002 dtex, and the total fineness of the other first and second intermediate warp yarns 45, 46 is set to 501 dtex.

Thus, the first and second intermediate warp yarns 45, 46 adjacent to the side edge warp yarns 44 are thicker than the other first and second intermediate warp yarns 45, 46, and are attached to the fastener element mounting portion 22 of the fastener tape 20. When the fastener element 14 is attached, the core wire 26 or the bag fabric portion 25 can be effectively prevented from being displaced on the side edge side of the chain cloth, and the core portion 24 is deformed so as to expand in the chain width direction, so that the fastener element 14 can be stably stabilized. Fastened and fixed around the core 24.

Further, the single fineness of each of the first and second intermediate warp yarns 45, 46 adjacent to the side edge warp yarns 44 and the other first and second intermediate warp yarns 45, 46 is set to 6.96 dtex/f. In this case, the first and second intermediate warp yarns 45, 46 adjacent to the side edge warp yarns 44 have 144 filaments, and the other first and second intermediate warp yarns 45, 46 have 72 filaments, either The number of filaments per 167 dtex of the first and second intermediate warp yarns 45 and 46 is set to 24 as shown in Fig. 6 .

Further, in the core portion 24 of the first embodiment, the maximum value (maximum width dimension W) of the core portion 24 in the state in which the fastener element 14 is not attached in the width direction of the chain is relative to the fastener element of the fastener element 14 The ratio of the total length E is 43% or more and 49% or less.

When the size of the core portion 24 is expressed by a specific size, for example, when the total length E of the fastener element 14 is set to 3.2 mm, the maximum width dimension of the core portion 24 in a state where the fastener element 14 is not attached is used. The W system is set to a size of 1.37 mm or more and 1.56 mm or less. In particular, in the first embodiment, the maximum width dimension W of the core portion 24 in a state where the fastener element 14 is not attached is set to 1.50 mm.

Further, another size is used to define the size of the core portion 24 of the fastener stringer 20, and the ratio of the maximum width dimension W of the core portion 24 in the state in which the fastener element 14 is not attached to the chain width C of the slide fastener 1 is set to 27% or more and 31% or less.

By forming the core portion 24 of the fastener stringer 20 with the maximum width dimension W as described above, the core portion 24 can be stably formed with an appropriate size for the fastener element 14 and the height dimension of the core portion 24 can be appropriately ensured. . Therefore, when the fastener element 14 is attached to the element attaching portion 22 of the fastener stringer 20, the core portion 24 of the fastener stringer 20 can be appropriately filled in the inner peripheral side space 14d of the leg portion 14c of the fastener element 14. Thereby, it is possible to prevent a gap from being generated in the inner peripheral side space 14d. Further, the width dimension of the core portion 24 is prevented from becoming excessively large, and the core portion 24 can be effectively prevented from overflowing from the inner peripheral side space 14d of the fastener element 14. Therefore, the fastener element 14 can be firmly and stably attached to the element attaching portion 22 of the fastener stringer 20 in a specific posture.

Further, as described above, in the core portion 24 of the first embodiment, all of the first and second intermediate warp yarns 45 and 46 forming the weave portion 25 are thicker than the warp yarn body 41 and the number of the filaments is small. The yarn can be formed to be relatively hard and have a high strength.

Here, the hardness of the core portion 24 in the present invention can be the core portion 24 of the fastener chain cloth 20 when the fastener element 14 is attached to the fastener element mounting portion 22 of the core portion 24 of the fastener chain 20 in a specific posture. The self-zipper element 14 is represented by the magnitude of the pressing force. In this case, the core portion 24 of the fastener tape 20 of the first embodiment has a hardness of 4 kgf or more, and is formed to be harder than the fastener tapes 80 and 90 of Patent Document 2 or Patent Document 3.

Further, the hardness of the core portion 24 in the fastener chain cloth 20 is obtained by, for example, holding a pair of special metal jigs corresponding to the metal fastener elements 14 in a form corresponding to the metal fastener elements 14 to hold the fastener chain cloth. In the sprocket attachment portion 22 of the 20, the pair of jigs are moved to the same state as the state in which the fastener elements 14 are fixed, and when the sprocket attachment portion 22 is held by the upper clamp, Measuring core by a pressure sensor mounted on the fixture The amount of pressure that the portion 24 receives from the clamp.

As described above, in the fastener stringer 20 of the first embodiment in which the hardness of the core portion 24 is 4 kgf or more, the fastener element mounting portion 22 including the core portion 24 is attached to the metal by the fastening processing as described above. When the fastener elements 14 are pulled, even if the core portion 24 is pressed by the fastener elements 14, the positions of the first and second intermediate warp yarns 45, 46 or the positions of the filaments constituting the core wire 26 are not easily offset, and the core portion 24 can be suppressed. The form is deformed in such a manner that the chain cloth is flattened in the front-back direction and expanded in the width direction of the chain cloth.

Therefore, it is possible to effectively prevent the core portion 24 from protruding from the leg portion 14c of the fastener element 14 when the fastener element 14 is implanted. Therefore, the core portion 24 can be stably attached to the specific position of the fastener stringer 20 in a specific posture without hindering the plastic deformation of the leg portion 14c of the fastener element 14.

Further, for example, when a plurality of fastener elements 14 are attached to the fastener stringer 20, usually, the fastener elements 14 are sequentially inserted into the fastener chain 20 one by one. In this case, in the fastener stringer 20 of the first embodiment, when the core portion 24 has the hardness as described above, even when the fastener element 14 is implanted in the fastener chain 20, even if the core portion 24 is The zipper element 14 is pressed and deformed into an elliptical shape which is slightly flattened in the direction of the front and back of the chain cloth, and the flattened shape of the core portion 24 can be easily applied to the portion of the chain portion where the fastener element 14 is not attached. Return to the original form.

Therefore, when the fastener element 14 disposed under the fastener element 14 is implanted into the fastener stringer 20, the fastener element can be smoothly attached to the core 24 having the original shape which is not flattened. 14. Therefore, even if a plurality of fastener elements 14 are sequentially attached to the fastener chain 20 one by one, the orientation of the fastener elements 14 can be prevented from being inclined with respect to the fastener chain 20, so that a plurality of fastener elements 14 can be stably obtained. A zipper tape 10 that is securely mounted in a specific posture.

As described above, in the fastener stringer 20 of the first embodiment, the core portion 24 can be formed in a manner suitable for hardness and strength without using the braided cord of Patent Document 1 described above. The height dimension of the core 24 is stably ensured, and the width dimension of the core 24 is controlled within a specific range with respect to the fastener element 14. Thereby, each of the fastener elements 14 can be firmly and stably fixed in a specific posture in the fastener element mounting portion 22 including the core portion 24 of the fastener chain cloth 20.

Therefore, the zipper 1 of the first embodiment can achieve a reduction in manufacturing cost by eliminating the need for a braided cord, and the mounting strength or sliding strength of the fastener element 14 with respect to the fastener stringer 20 is high, and the slider 30 is High quality zipper 1 with excellent operability or slidability.

Further, in the first embodiment described above, the first and second intermediate warp yarns 45 and 46 adjacent to the side edge warp yarns 44 of the first and second intermediate warp yarns 45 and 46 disposed in the bag fabric portion 25 are formed to be relatively thin. The other first and second intermediate warp yarns 45 and 46 are thick, but in the present invention, all of the first and second intermediate warp yarns 45 and 46 disposed in the bag fabric portion 25 are thicker than the chain fabric body warp yarn 41 of the chain body 23. The thickness of the first and second intermediate warp yarns 45, 46 can be arbitrarily changed. For example, the first and second intermediate warp yarns 45, 46 adjacent to the side edge warp yarns 44 may be formed such that the first and second intermediate warp yarns 45, 46 are thicker than the other first and second intermediate warp yarns 45, 46. The same thickness.

Further, for example, in the case of the fastener stringer 20a according to the modification of the first embodiment, as shown in Fig. 9, the first and second intermediate warp yarns 45a and 46a disposed in the bag-woven portion 25a may be adjacent to the side edge warp yarns 44a. The first intermediate warp yarns 45a and 46a and the first and second intermediate warp yarns 45a and 46a adjacent to the main body side warp yarns 43a are formed thicker than the other first and second intermediate warp yarns 45a and 46a to form a bag-woven portion 25a.

Thus, the first and second intermediate warp yarns 45a and 46a adjacent to the side edge warp yarns 44a and the first and second intermediate warp yarns 45a and 46a adjacent to the main body side warp yarns 43a are made larger than the other first and second intermediate warp yarns. 45a and 46a are thick, and when the fastener element 14 is attached to the element attaching portion 22a of the fastener stringer 20a, the core wire 26 or the bag-like portion 25a can be effectively prevented from shifting toward the opposite side edge side of the chain cloth and the chain body 23 side. Further, the width of the core portion 24a becomes large, so that the fastener element 14 can be stably fixed around the core portion 24a.

Further, in the first embodiment described above, the first intermediate warp yarn 45 is disposed in the bag fabric portion 25. In the present invention, the number of the first and second intermediate warp yarns is not particularly limited and may be arbitrarily changed. In particular, in the present invention, it is preferable to set the number of the first and second intermediate warp yarns to four or more and nine or less.

For example, in FIG. 10, as another modification of the first embodiment, the fastener chain 20b formed by setting the number of the first and second intermediate warp yarns 45b and 46b to four is shown. By the number of the first and second intermediate warp yarns 45b and 46b being four or more, the core portion can be formed in a large and stable manner in a specific form, as in the case of the fastener tape 20b shown in FIG. 24b and can ensure the height dimension of the core 24b.
