Description

  The present invention uses a double warp knitting machine having two rows of needle beds, and simultaneously knitting a fastener tape having a tape main part and an element attachment part, and at the same time, a continuous fastener at an element attachment part knitted in a double structure The present invention relates to a braided fastener stringer in which elements are braided and attached.

  Conventionally, for example, using a double warp knitting machine having two rows of needle beds such as a double raschel knitting machine, the fastener tape is knitted, and at the same time, the element attachment portion along the length direction of the fastener tape is continuous. A fastener stringer (knitted fastener stringer) for a knitted slide fastener obtained by knitting a fastener element is known.

  An example of such a braided fastener stringer is disclosed in JP-A-8-228813 (Patent Document 1). A knitted fastener stringer described as one example in Patent Document 1 is shown in FIGS. In FIG. 11, the knitting structure is shown in a state where the stitches are loosened in order to make the knitting structure in the element attachment portion of the fastener tape easy to understand.

  The knitted fastener stringer 50 of Patent Document 1 includes a fastener tape 51 having a warp knitted structure and a continuous (coiled) fastener knitted on an element attachment portion 51 a formed on a longitudinal side edge of the fastener tape 51. And an element 52.

  The ground structure of the fastener tape 51 includes a chain knitting yarn 61 (1-0 / 0-0 / 0-1 / 1-1) and a tricot knitting yarn 62 (1-2 / 1-1-1-0 / 1-). 1) and a weft insertion thread 63 (0-0 / 2-2 / 4/4 / 2-2) inserted in a zigzag manner across the four wales of the fastener tape 51.

  Of the three wales constituting the element mounting portion 51a, the two wales arranged closer to the main part of the tape are fixed chain braids having a double knitting structure by the back needle row (B) and the front needle row (F). Yarns 64 (0-1 / 1-0 / 1-1-0 / 0-1) are knitted, respectively.

  In the fixing chain knitting yarn 64, as shown in FIG. 11, the first needle loop 64a (back side needle loop) formed by the back needle row is the needle loop of the above-described chain knitting yarn 61 and the tricot knitting yarn. It is knitted into the ground structure of the element mounting portion 51a so as to be intertwined with the 62 needle loops, thereby forming a dense ground structure.

  The second needle loop 64b (front side needle loop) of the fixing chain knitting yarn 64 formed by the front needle row straddles the pair of upper and lower leg portions of the fastener element 52 and is formed in the second order. Intertwined with the needle loop 64b, the upper and lower leg portions of the fastener element 52 are pressed against and fixed to the ground structure of the element mounting portion 51a.

  In this case, in particular, as shown in FIGS. 10 and 11, two first and second needle loops 64a and 64b are formed on the fixing chain knitting yarn 64 for each pitch in the tape length direction of the fastener element 52. In addition, the upper and lower leg portions of the fastener element 52 are shifted in the length direction so as to pass through different courses.

  Then, the sinker loop of the fixing chain knitting yarn 64 is inserted between the upper and lower leg portions of the fastener element 52, and the upper leg portion and the lower leg portion of the fastener element 52 are respectively pressed by separate second needle loops 64b. It is fixed.

  In the knitted fastener stringer 50 of Patent Document 1 configured as described above, the first needle loop 64a of the fixing chain knitting yarn 64 is knitted into the ground structure of the element mounting portion 51a. The part 51a can be composed of a dense structure. In addition, the upper and lower leg portions of the fastener element 52 are fastened and fixed by the second needle loop 64b of the fixing chain knitting yarn 64. In particular, in this embodiment, the upper leg portion and the lower leg portion are separated by the separate second needle loop 64b. Each is fixed. For this reason, according to Patent Document 1, the stretchability of the element attachment portion 51a in the fastener tape 51 is almost lost, and the fastener element 52 can be fixed to the element attachment portion 51a in a dimensionally stable state.

  As another example, Patent Document 1 discloses a braided fastener stringer 55 as shown in FIG. 12. In this braided fastener stringer 55, a double structure is provided on an element mounting portion 56a of the fastener tape. The fixing chain knitting yarn 64 is knitted, and the fixing chain knitting yarn 64 is formed with a first and every first pitch of the fastener element 52 in order to form the element attaching portion 56a of the fastener tape with a dense structure. Two second needle loops 64a and 64b are provided.

  In this case, the pair of upper and lower leg portions of the fastener element 52 are formed so as to be overlapped in the tape front and back direction so as to be inserted through the same course, and the pair of upper and lower leg portions are formed on every other second needle loop 64b. It is inserted at the same time and is fastened and fixed to the element mounting portion 56a by the second needle loop 64b.

  That is, in the braided fastener stringer 55 according to the other embodiment, the second needle loop 64b that fixes the upper and lower leg portions of the fastener element 52 to the fixing chain knitting yarn 64 and the second needle loop 64b that does not fix the upper and lower leg portions. Needle loops 64b are alternately arranged. Even with such a braided fastener stringer 55, the stretchability of the element attachment portion 56a in the fastener tape is almost lost, and the fastener element 52 can be fixed to the element attachment portion 56a in a dimensionally stable state.

JP-A-8-228813

  In the braided fastener stringer described in Patent Document 1, as described above, in order to stably fix the fastener element 52 to the element attachment portion of the fastener tape, a double-tissue fixed chain yarn 64 is a fastener. Each element 52 has two first and second needle loops 64a and 64b for each pitch, and is knitted into the element mounting portion so as to press and fix the upper and lower legs of the fastener element 52 with the second needle loop 64b. ing.

  By the way, in general, a fastener tape made of a warp knitted structure has an advantage that it is superior in flexibility and texture, for example, compared to a fastener tape made of a woven structure. Knitted slide fasteners that are knitted are often used for thin clothing such as underwear.

  However, when the chain stitch yarn 64 for fixing with a double structure is knitted into the element mounting portion 51a as in the braided fastener stringer of Patent Document 1, for example, the chain stitch yarn for fixing 64 is the fastener element as described above. 52, the knitting structure of the element mounting portion becomes dense by the first needle loop 64a, so that the knitting structure of the element mounting portion becomes dense. Elasticity is impaired.

  In Patent Document 1, the upper and lower leg portions of the fastener element 52 are fastened and firmly attached by the second needle loop 64b of the fixing chain knitting yarn 64. On the other hand, the upper and lower leg portions of the fastener element 52 are fixed. The movement is limited by the second needle loop 64b which is knitted tightly, and as a result, the element mounting portion is difficult to bend in the front and back direction and the width direction of the fastener tape. For this reason, the knitted fastener stringer of Patent Document 1 causes a decrease in flexibility and texture, and the characteristics that the knitted fastener stringer should originally have may be impaired.

  Moreover, when manufacturing a braided fastener stringer, in order to reduce manufacturing cost, it is requested | required to raise the knitting speed of the knitting machine which knits a fastener stringer, and to improve production efficiency. However, in the case of the knitted fastener stringer disclosed in Patent Document 1, two first and second needle loops 64a and 64b of the fixing chain knitting yarn 64 are formed for each fastener element for one pitch, for a total of four. Since it is necessary to make stitches, there are limits to increasing the knitting speed, and it has been difficult to improve production efficiency and reduce manufacturing costs.

  The present invention has been made in view of the above-described conventional problems. A specific object of the present invention is to provide a knitted fabric even when a fastener element is knitted and fixed to an element mounting portion using a double-structure fixing chain knitting yarn. An object of the present invention is to provide a knitted fastener stringer capable of preventing loss of specific flexibility and texture and increasing the knitting speed and reducing the manufacturing cost.

  In order to achieve the above object, a braided fastener stringer provided by the present invention includes, as a basic configuration, a fastener tape having a warp knitting structure in which an element attachment portion is disposed along one side edge of a tape main portion. A continuous fastener element that is braided and fixed to the element attachment portion simultaneously with the knitting of the fastener tape, and the element attachment portion has at least a pair of upper and lower leg portions of the fastener element in the tape front and back direction. The fixing chain knitting yarn is clamped and fixed, and the fixing chain knitting yarn includes a first needle loop that is knitted into the ground structure of the element mounting portion, and a second needle loop that clamps and fixes the upper and lower leg portions. The first and second needle loops of the fixing chain knitting yarn have the flanges. It is formed, one for each one pitch of the scan toner element, in which the second needle loop with most major characterized by being fastened to the element attaching portion across a pair of the upper and lower leg portions.

  In the braided fastener stringer according to the present invention, the first weft insertion thread that is inserted across the two or more rows of wales and the two or more rows of wales, and the ground structure of the tape main portion and the element mounting portion. Preferably, the first weft insertion yarn and the second weft insertion yarn inserted in the direction intersecting between the courses are arranged.

  Further, in the braided fastener stringer of the present invention, the tape main part has an ear part constituted by two or more rows of wales on the other side edge side of the tape main part, and the ear part includes the first part. It is preferred that the two weft insertion yarn is eliminated.

  Furthermore, in the braided fastener stringer of the present invention, a two-dimensional knitting yarn or a tricot knitting yarn is knitted into the ground structure of the tape main portion, and a two-dimensional knitting yarn or a tricot knitting yarn is formed into the ground structure of the element mounting portion. It is preferable that it is knitted.

  In the braided fastener stringer according to the present invention, a first needle loop in which an element attachment portion disposed over one side edge portion of the fastener tape over at least two wales is knitted into the ground structure of the element attachment portion, and a fastener element These are knitted with a double structure using a chain knitting yarn for fixing having a second needle loop that fastens and fixes the pair of upper and lower leg portions.

  In particular, in the present invention, for each pitch in the tape length direction of the fastener element, the first and second needle loops are formed one by one with the chain stitch yarn for fixing, and one second needle loop is formed. Each time, a pair of upper and lower leg portions are inserted, and the upper and lower leg portions are firmly clamped and fixed to the element mounting portion by the second needle loop of the fixing chain braiding yarn.

  In addition, in this invention, the pitch of a fastener element is the magnitude | size of the space | interval in the tape longitudinal direction between the centerlines of the meshing head adjacent to each other in a continuous fastener element.

  Thus, in the braided fastener stringer of the present invention, the first and second needle loops of the chain stitch yarn for fixing are formed at a ratio of one to one pitch of the fastener element. Compared to one knitted fastener stringer, the number of stitches formed on the chain stitch yarn for fixing per unit length is reduced. For this reason, the knitting speed at the time of knitting of the fastener stringer can be greatly increased (the knitting speed in the present invention can be increased to twice the knitting speed in Patent Document 1 by simple calculation). Therefore, according to the present invention, the production efficiency of the braided fastener stringer can be increased more easily than before, and the manufacturing cost can be greatly reduced.

  In the present invention, the interval in the tape length direction of the stitch formed on the element attachment portion can be made larger than that of, for example, the knitted fastener stringer disclosed in Patent Document 1 (in other words, the stitch in the wale direction at the element attachment portion). The density can be reduced, and the ground structure of the element mounting portion is configured to be coarser in the tape length direction than in Patent Document 1. For this reason, it can suppress that the stretchability of an element attachment part is impaired by knitting the chain stitch yarn for fixation like patent documents 1.

  In addition, the second needle loop of the present invention fastens and fixes the upper and lower leg portions of the fastener element to the element mounting portion, and more easily allows the movement of the upper and lower leg portions in the fastener element than in Patent Document 1, The part can be easily folded in the tape front and back direction and the width direction.

  Further, in this case, the stitch density in the wale direction in the tape main part is also reduced, so that the tape main part can be formed softer. Therefore, the braided fastener stringer of the present invention is configured as a high quality braided fastener stringer which is rich in flexibility, rich in texture and soft.

  In such a braided fastener stringer of the present invention, the first weft insertion thread that is inserted across the two or more rows of wales and the two or more rows of wales and the ground structure of the tape main body and the element mounting portion The first weft insertion yarn and the second weft insertion yarn inserted in the direction intersecting between the courses are arranged.

  By arranging such first and second weft insertion yarns, the fastener tape reinforces the tape main portion and the element mounting portion while appropriately maintaining the original flexibility and texture of the knitted fabric, The ground structure (stitch form) can be configured firmly and strongly.

  As a result, the fastener element can be knitted and fixed at a predetermined position with high accuracy and stability to the element mounting portion, and the fastener element can be tilted toward the tape surface of the fastener tape. It can prevent falling (rolling). For this reason, for example, when a slide fastener is configured using the braided fastener stringer of the present invention, it is possible to effectively increase the meshing strength in the left and right element rows and make it difficult to cause meshing cracks in the element rows.

  In addition, the tape main part is firmly and strongly configured and its tape form is stable, so that the fastener tape can be sewn stably when the tape main part of the fastener tape is sewn to a product such as clothing. However, the position of the fastener tape with respect to the fastener-attached product is less likely to occur.

  Moreover, even if such first and second weft insertion yarns are arranged, the stretchability of the fastener tape can be secured stably, and even if the fastener tape is repeatedly stretched in the length direction, the original length is stable. The entire tape width can be shrunk in a well-balanced manner.

  In this case, the first and second weft insertion yarns are preferably inserted across two or three rows of wales in order to more effectively stabilize the ground structure of the tape main portion and the element mounting portion. .

  In the braided fastener stringer of the present invention, the tape main part has an ear part composed of two or more wales on the other side edge side of the tape main part, and the ear part has a second weft insertion thread. Excluded and formed. Thus, since the ear | edge part does not have the 2nd weft insertion thread | yarn, an ear | edge part can be comprised more softly and the softness | flexibility of the whole fastener tape can be improved effectively.

  Furthermore, in the braided fastener stringer of the present invention, the fastener tape has a two-dimensional knitting yarn or a tricot knitting yarn knitted in the ground structure of the tape main portion, and a two-dimensional knitting yarn in the ground structure of the element mounting portion. Alternatively, a tricot knitting yarn is knitted.

  In this way, by using the second stitch yarn or tricot stitch yarn for the tape main portion and the element mounting portion, the stitches of adjacent wales can be reliably connected to each other, and the stitch positions at the respective wales are warp and weft directions. Therefore, the knitting structure of the tape main body part and the element attachment part can be configured firmly and stably. Thereby, fixation to the element attachment part of a fastener element and the sewing to the fastener adherence product of a fastener tape can be stabilized further.

  In this case, a knitting structure in which a second stitch yarn is knitted in the tape main portion and the element mounting portion, a second stitch yarn in the tape main portion, a knitting structure in which a tricot knitting yarn is knitted in the element mounting portion, and the tape main portion. One knitting structure can be selected from four types: tricot knitting yarn, knitting structure in which second stitch knitting yarn is knitted in the element mounting part, and knitting structure in which tricot knitting yarn is knitted in the tape main part and element mounting part. Among them, by adopting a knitting structure in which a second stitch yarn is knitted in the tape main body part and the element mounting part, it is possible to more effectively prevent the stitches from being displaced, A knitted structure with improved dimensional stability can be formed.

FIG. 3 is a partial perspective view schematically showing a knitting structure of an element attachment portion in the knitted fastener stringer of the first embodiment.

  In FIG. 3, in order to show the characteristics of the first embodiment in an easy-to-understand manner, illustration of the second knitting yarn arranged on the fastener tape is omitted, and the knitting structure is shown in a loosened state. . Moreover, in the following description, the longitudinal direction of the fastener tape is defined as the course direction, and each wale described later extends in the course direction. Furthermore, the direction orthogonal to the longitudinal direction on the plane of the fastener tape is defined as the width direction of the fastener tape.

  The braided fastener stringer 1 of the first embodiment includes a fastener tape 10 having a tape main body 11 and an element mounting portion 12 and a continuous fastener element 20 that is braided and fixed to the element mounting portion 12. Yes. In this case, the fastener element 20 is configured in the same manner as a general fastener element used in the conventional braided fastener stringer 1, and the size and mounting pitch of the fastener element 20 are set in the same manner as the conventional one. Has been.

  That is, the fastener element 20 according to the first embodiment includes a meshing head 21, upper and lower leg portions 22 extending from the meshing head 21 in the tape width direction, and a connecting portion 23 that connects adjacent fastener elements 20 (inverted). For example, the mesh head 21 is formed by pressing a monofilament made of synthetic resin at a predetermined interval by stamping, and then the monofilament is wound in a coil shape. Has been.

  In the fastener element 20, the meshing head 21 has a tape side edge on the element mounting portion 12 side of the fastener tape 10 (hereinafter, the tape side edge is referred to as a tape inner edge, and the opposite tape side edge is referred to as a tape outer edge). The upper and lower leg portions 22 are knitted and fixed to the element mounting portion 12 simultaneously with the knitting of the fastener tape 10 so as to protrude outward.

In this case, the upper and lower leg portions 22 of the fastener element 20 run in the weft direction within the same course across the three rows of the first wal W ₁ to the third wal W ₃ constituting the element mounting portion 12. It is fastened and fixed in the tape front and back direction by a fixing chain knitting yarn 35 (described later) knitted on the second and third wales W ₂ and W ₃ .

The fastener tape 10 of the first embodiment is knitted using a double warp knitting machine having two rows of needle beds, and the total tape width of the fastener tape 10 is n rows of the first wal W ₁ to the n wales W. It is composed of _n . In this case, the most one column of wales disposed in the tape inside edge and the first wale W ₁ in the fastener tape 10, the n-th column of the wale which are located nearest the tape outer edge side and the n wale W _n.

The fastener tape 10 includes a tape main body portion 11 having a warp knitting structure and an element attachment portion 12 that is integrally knitted along one side edge of the tape main body portion 11. In the first embodiment, as shown in FIG. 1, the element mounting portion 12 is configured by the first wale W ₁ to the third wale W ₃ , and is doubled using the back needle row B and the front needle row F. It is organized by organization.

The tape main body 11 is composed of the fourth wal W ₄ to the n-th wal W _n , and is knitted with a single structure using a single back needle row B. In this case, in the first embodiment, for one pitch of the fastener element 20, a needle loop (back-side needle loop) formed by the back needle row B in the tape main body portion 11 and the element mounting portion 12, and the element The fastener tape 10 is knitted in such a ratio that needle loops (front side needle loops) formed by the front needle row F in the attachment portion 12 are formed one by one in the tape length direction.

Further, in the fastener tape 10 of the embodiment 1, toward the n-2 wales W _n-2 ~ n-th wale W _n in the tape outer edge of the tape main body portion 11 is stably held in the form of fastener tapes 10 Ear portions 13 are formed. In the present invention, the number of wales constituting the element attaching portion 12, the tape main portion 11, and the ear portion 13 can be arbitrarily set or changed according to the size of the slide fastener or the fastener element 20. It is.

  In the first embodiment, the knitting structure of the tape main body 11 knitted using a single back needle row B is a ground chain knitting yarn 31 (0-1 / 1-1-1-1- 0 / 0-0), a second stitch yarn 32 (2-0 / 0-0 / 0-2 / 2-2), and a first weft insertion yarn 33 inserted in a zigzag manner across three wales. (0-0 / 2-2 / 4-4 / 2-2) and the second weft insertion thread which is inserted in a zigzag manner in the direction crossing between the first weft insertion thread 33 and the course while straddling the two wales 34 (2-2 / 1-1 / 0-0 / 1-1).

  As described above, the ground chain knitting yarn 31 and the second stitch knitting yarn 32 are arranged on the tape main body 11, so that two needle loops are formed on each stitch and entangled, and are arranged on adjacent wales. The needle loops are reliably connected by the sinker loop of the second stitch yarn 32. Thereby, it can prevent that each thread 31-34 which comprises the tape main-body part 11 moves to a warp direction or a weft direction, and comprises the tape main-body part 11 by the firm knitting structure | tissue whose position of a stitch is hard to shift | deviate. Can do.

  Further, since the first and second weft insertion threads 33 and 34 are inserted into the tape main part 11, the tape main part 11 is effectively held while appropriately maintaining the flexibility and texture of the fastener tape 10. It can reinforce and can stabilize the form of tape main part 11 more. Here, when the first weft insertion thread 33 and the second weft insertion thread 34 intersect between courses, the direction in which the first weft insertion thread 33 is folded and the direction in which the second weft insertion thread 34 is folded back are the course directions. It is said that it is shifted by one.

  In addition, in order to increase the flexibility of the braided fastener stringer 1, the ear portion 13 in the tape main body portion 11 does not use the second weft insertion yarn 34, but the ground chain knitting yarn 31, the second stitch knitting yarn 32, and The first weft insertion thread 33 is composed of three types of yarns.

On the other hand, the knitting structure of the element mounting portion 12 knitted by the double structure includes the ground chain knitting yarn 31 knitted on the first wale W ₁ and the fixed chain knitting knitted on the second and third wales W ₂ and W ₃ . Yarn 35 (1-0 / 0-1 / 1-0 / 0-1), a second knitting yarn 32, a first weft insertion yarn 33, and a second weft insertion arranged continuously from the tape main body 11 The thread 34 is used.

  In the element mounting portion 12, the ground chain knitting yarn 31 and the second stitch knitting yarn 32 are knitted while forming a needle loop at the needle position of the back needle row B. The fixing chain knitting yarn 35 forms a first needle loop (back side needle loop) 35a knitted into the ground structure of the element mounting portion 12 at the needle position of the back needle row B, and It is knitted while forming a second needle loop (front needle loop) 35b that presses across the upper and lower leg portions 22 of the fastener element 20 at the needle position.

  In this case, as shown in FIG. 3 and FIG. 4, the fixing chain knitting yarn 35 has a first pitch between one pitch of the fastener elements 20 (the size of the interval in the length direction between adjacent meshing heads 21). In addition, the second needle loops 35a and 35b are knitted while forming the stitches at a rate of forming one by one.

  Each time the second needle loop 35 b is formed by the chain stitch yarn 35 for fixing, the pair of upper and lower leg portions 22 of the fastener element 20 is inserted into the same course of the element mounting portion 12. As a result, each second needle loop 35b surely straddles the pair of upper and lower leg portions 22 and entangles with the second needle loop 35b formed in the next position, so that each upper and lower legs of the fastener element 20 are formed by each second needle loop 35b. The portion 22 is stably clamped and fixed to the element mounting portion 12.

  Further, the first needle loop 35a of the fixing chain knitting yarn 35 is entangled with the needle loops of the ground chain knitting yarn 31 and the second stitch knitting yarn 32 to form the ground structure of the element mounting portion 12, and further, the element mounting By inserting the first and second weft insertion threads 33 and 34 into the ground structure of the portion 12, the element mounting portion 12 is firmly and strongly configured while appropriately maintaining flexibility and texture.

  The knitted fastener stringer 1 of Example 1 is knitted with the knitting structure as described above, and then heat set, so that the knitting structure and form of the fastener tape 10 are fixed and held. The

  As described above, in the braided fastener stringer 1 of the first embodiment, the length of one pitch of the fastener element 20 itself is not different from the fastener element in the conventional general braided fastener stringer and has substantially the same dimensions. A back side needle loop formed by the back needle row B and a front side needle loop formed by the front needle row F with respect to the length of one pitch of the fastener element 20. Are formed one by one in the tape length direction, and the number of stitches of the fastener tape 10 relative to the pitch of the fastener elements 20 (particularly, the first and The relative number of second needle loops 35a and 35b) is smaller than before. There.

  That is, in the first embodiment, the number of stitches formed per unit length of the knitted fastener stringer 1 (the number of the first and second needle loops 35a and 35b of the fixing chain knitting yarn 35) is larger than that of the conventional example. Since it is greatly reduced, the knitting speed when knitting the knitted fastener stringer 1 can be easily increased, and the production efficiency can be improved and the manufacturing cost can be greatly reduced.

  In particular, in the first embodiment, the number of the first and second needle loops 35a and 35b formed per unit length of the fixing chain knitting yarn 35 is reduced, so that the upper and lower leg portions of the fastener element 20 are reduced. While 22 is appropriately fastened and fixed to the element mounting portion 12 with the fixing chain knitting yarn 35, the movement of the upper and lower leg portions 22 can be allowed in a minute range.

  Thereby, the braided fastener stringer 1 of the first embodiment can easily bend the element mounting portion 12 in the tape front / back direction or the width direction while ensuring an appropriate meshing strength of the element row when the slide fastener is formed. It is possible to stably obtain a supple flexibility and soft texture. Such a braided fastener stringer 1 of the first embodiment is particularly preferably applied to, for example, a small-sized braided fastener stringer in which the pitch of the fastener elements 20 is set to be small.

  In addition, in this invention, it is not limited to the structure of the braided fastener stringer 1 of Example 1 mentioned above, and the structure of the braided fastener stringers 2-4 of Example 2-Example 4 mentioned later, A slide fastener Depending on the functions and uses required for the above, the type of constituent yarns constituting the braided fastener stringer, the form of the braided fastener stringer, and the like can be arbitrarily changed.

For example, when the flexibility of the braided fastener stringer 1 is further improved, the ground chain knitting yarn 31 arranged in the _n- 2th wale Wn _-2 to the nth wale Wn constituting the ear portion 13 is used. or, the foundation chain knitting yarn 31 that is disposed to the n wale W _n that is disposed most tape outer edge side is formed by the water-soluble yarn.

  Then, after the knitted fastener stringer 1 is knitted, the ground chain knitting yarn 31 can be dissolved and eliminated by immersing the knitted fastener stringer 1 in a liquid (for example, water). . Thereby, the elasticity of the ear | edge part 13 of the fastener tape 10 can further be improved, and the softness | flexibility of the knitted fastener stringer 1 whole can be improved.

Further, for example, when a slide fastener is configured, at least one wale (for example, for example) constituting the element mounting portion 12 in order to make it difficult for the element row to mesh with the force in the tape front and back direction (push-up force). It is also possible to insert a warp insertion yarn 38 running in a zigzag shape in the warp direction in the first and second wales W ₁ , W ₂ ) (see a modification of the fourth embodiment shown in FIG. 9).

  Moreover, although the braided fastener stringer 1 of Example 1 mentioned above is comprised as a fastener stringer used for a normal type slide fastener, for example of the meshing head of the fastener element fixed to the element attachment part of a fastener tape, for example. By changing the direction, it may be configured as a braided fastener stringer for a hidden slide fastener.

  For example, when manufacturing a fastener stringer for a hidden slide fastener, when the fastener tape 10 is knitted, the meshing head of the fastener element is directed from the boundary between the element mounting portion 12 and the tape main portion 11 to the tape main portion 11 side. In the posture, the upper and lower leg portions of the fastener element are fastened and fixed by the fixing chain knitting yarn 35.

Then, after the knitted fastener stringer is knitted, the element mounting portion 12 of the fastener tape 10 is folded back to the tape main body 11 side along the boundary of the previous operation, and the meshing head of the fastener element from the folded U-shaped folded portion The heat setting process is performed with the protruding outward. This provides a braided fastener stringer for the hidden slide fastener.
Even with such a knitted fastener stringer for a hidden slide fastener, the same effects as those of the normal type knitted fastener stringer 1 in the first embodiment can be obtained.

  In the second embodiment as well, one needle loop formed by the back needle row B and one needle loop formed by the front needle row F are formed one by one in the tape length direction with respect to the 1-pitch fastener element 20. The fastener tape 10a is knitted at the ratio of being performed.

In this case, the knitting structure of the tape main body portion 11a includes a foundation chain knitting yarn 31 that is disposed to each wale, first tricot knitting yarns 36 disposed in the region of the third wale W ₃ ~ n-th wale W _n (1 -2 / 1-1 / 1-0 / 1-1) and second tricot knitting yarn 37 (1-0 / 1-1-1 / 1-2 / 1-1), and first and second weft insertion yarns 33 , 34. In this way, the ground chain knitting yarn 31 and the first and second tricot knitting yarns 36 and 37 are arranged on the tape main portion 11a, so that the knitting structure of the tape main portion 11a can be stably formed, and the stitches The position can be prevented from shifting.

  The braided fastener stringer 2 of the second embodiment is also a relative stitch formed by the back needle row B and the front needle row F with respect to the pitch of the fastener element 20 as in the first embodiment. The number (particularly, the relative number of the first and second needle loops 35a and 35b of the fixing chain knitting yarn 35) is small.

  For this reason, the knitting speed at the time of knitting the braided fastener stringer 2 can be easily increased, and an improvement in production efficiency and a significant reduction in manufacturing cost can be achieved. Further, the braided fastener stringer 2 according to the second embodiment can stably obtain a flexible flexibility and a soft texture while ensuring an appropriate meshing strength of the element row when the slide fastener is configured.

FIG. 7 is an organization chart showing a knitting structure of the fastener tape in the knitted fastener stringer according to the third embodiment.
The fastener tape 10b in the third embodiment, the tape main portion 11b which is knitted in a single tissue using a back needle row B (fourth wales W ₄ ~ n-th wale W _n), back needle row B and the front needle row and a and element attaching portion 12b which is knitted in a double structure by using the (first wale W ₁ ~ third wale W ₃₎ F, the tape outer edge of the tape main portion 11b, the ear portion is not shown Is formed.

  Also in the third embodiment, a needle loop formed by the back needle row B and a needle loop formed by the front needle row F are formed one by one in the tape length direction with respect to the 1-pitch fastener element 20. The fastener tape 10b is knitted at the ratio of being performed.

The knitting structure of the tape main part 11b is similar to the above-described second embodiment. The ground chain knitting yarn 31, the first and second tricot knitting yarns 36 and 37, the first and second weft insertion yarns 33 and 34, and It is comprised using. Moreover, the knitting structure of the element attaching portion 12b is provided with a foundation chain knitting yarn 31 knitted into the first wale W _1, the fixing chain knitting yarn 35 knitted into the second and third wales W _2, W _3, the tape main The first tricot knitting yarn 36, the second tricot knitting yarn 37, the first weft insertion yarn 33, and the second weft insertion yarn 34, which are continuously arranged from the portion 11b, are used.

  The braided fastener stringer 2 of the third embodiment is also relatively formed by the back needle row B and the front needle row F with respect to the pitch of the fastener element 20 as in the first and second embodiments. Since the number of stitches is small, the same effects as those of the first and second embodiments can be obtained.

  Furthermore, in the knitted fastener stringer 3 of the third embodiment, the knitting structure of the tape main body portion 11b and the element mounting portion 12b is the first and second without using the second stitch yarn 32 as in the first embodiment. Since it is configured using the two tricot knitting yarns 36 and 37, the knitting speed of the knitted fastener stringer 2 can be increased as compared with the case of the first embodiment, and the production efficiency can be further improved.

FIG. 8 is a structure diagram showing the knitted structure of the fastener tape in the knitted fastener stringer according to the fourth embodiment.
In the fastener tape 10c of the fourth embodiment, is broadly configured than the above-described first embodiment the element attaching portion 12c is over the first wale W ₁ ~ fourth wale W _4, in the element attaching portion 12c, upper and lower leg portions Fastener elements 20c having a length 22c in the tape width direction are fastened and fixed by using a chain stitch yarn 35 for fixing. Further, the tape main portion 11c is constructed over the fifth wales _{W 5} ~ n-th wale _{W n.}

In this case, the knitting structure of the tape main body portion 11c and the element attachment portion 12c is substantially the same as that of the knitted fastener stringer 1 according to the first embodiment. That is, the knitting structure of the tape main part 11 c is configured using the ground chain knitting yarn 31, the second stitch knitting yarn 32, and the first and second weft insertion yarns 33 and 34. Moreover, the knitting structure of the element attaching portion 12c includes a foundation chain knitting yarn 31 knitted into the first wale W _1, the fixing chain knitting yarn 35 knitted into the second wale W ₂ ~ fourth wale W _4, the tape main The second knitting yarn 32, the first weft insertion yarn 33, and the second weft insertion yarn 34 that are continuously arranged from the portion 11c are used.
Even with the braided fastener stringer 4 of the fourth embodiment in which such element mounting portions 12c are formed widely, the same effects as those of the first embodiment can be obtained.

In Example 4, for example, as shown in a structural diagram of a fastener tape 10d according to a modification in FIG. 9, the ground structure side (back needle) of the first and second wales W ₁ and W ₂ in the element mounting portion 12d is shown. A warp insertion yarn 38 (0-0 / 1-1-1 / 1 / 0-0) running in a zigzag shape in the warp direction can be further inserted into the needle loop side formed by the row B).

  By inserting the warp insertion thread 38 into the predetermined wales constituting the element mounting portion 12d as described above, the ground structure of the element mounting portion 12d is reinforced while securing the flexibility of the element mounting portion 12d, and the tape The form can be made more stable.

  Thereby, since fixation of the fastener element 20 with respect to the element attachment part 12d can be stabilized more, when a slide fastener is comprised, for example, when the slide fastener in a closed state is a thrust force in the tape front and back direction (particularly, the tape back surface) Even when receiving a tape front-and-back direction pushing-up force applied from the side to the tape surface side, the meshing state of the element rows can be stably maintained, and the occurrence of meshing cracks in the element rows can be prevented.

  In this case, the insertion number and insertion position of the warp insertion thread 38 can be arbitrarily changed. For example, the warp insertion thread 38 can be inserted into all wales constituting the element mounting portion 12d. It is also possible to insert the warp insertion thread 38 into a part or all of the wales constituting the tape main part 11d.

  Further, in the wale in which the fixing chain knitting yarn 35 is knitted, the warp insertion yarn 38 is inserted into the needle loop side formed by the back needle row B as described above, and the front needle row F is formed. It is also possible to insert a warp insertion thread 38 on the needle loop side. It is also possible to insert the warp insertion thread 38 only on the needle loop side formed by the front needle row F without inserting the warp insertion thread 38 on the needle loop side formed by the back needle row B. .

  By inserting the warp insertion thread 38 only on the needle loop side formed by the front needle row F in this way, when the slide fastener is configured using the braided fastener stringer 5, the slide fastener in the closed state is Even if a thrust force from the tape front side toward the tape back side is applied, it is possible to effectively prevent the meshing of the element rows from occurring.

  In the first to third embodiments described above, the fastener element 20 is fixed by the fixing chain knitting yarn 35 that forms two rows of wales. Yarn may be knitted to fix the fastener element.
