technical field

The present invention relates to a braided fastener tape in which a continuous element row is woven and fixed on the fastener tape while weaving the fastener tape, and particularly relates to a weaving of a fastener tape with improved stretchability and softness and good appearance quality Zip and tooth chain straps.

Background technique

Unexamined-Japanese-Patent No. 2008-93210 (patent document 1) discloses a curved slide fastener in which a fastener tape has a curved shape as a slide fastener attached to an opening of a bag, clothes, or the like. Here, the slide fastener described in Patent Document 1 will be briefly described with reference to FIG. 7 .

The slide fastener of Patent Document 1 has: a pair of woven left and right fastener tapes 40 ; after each fastener tape 40 is woven, an unshown coil-shaped continuous chain is sewn along the opposite side edges of the fastener tape 40 . tooth row; a slider, not shown, that slides along a continuous chain tooth row. In addition, in Patent Document 1, in order to keep the zipper in a curved form, an unillustrated belt-shaped stretchable belt is fixed to the outside side edges (side edges on the opposite side to the opposite side edges) of the left and right zipper tapes 40 . part.

Furthermore, the fastener tape 40 of patent document 1 is comprised with the warp-knitted tape knitted with the many knitting yarns, as shown in FIG. 7, in order to make a tape bend easily. In this fastener tape 40, an element attaching portion 40a is formed in a range from the first wale W1 to the fourth wale W4 arranged on the side closest to the opposite side edge, and the fifth wale W5 to the fifth wale W5 to the fourth wale W4. The fourteenth wale W14 forms the tape main body portion 40 b , and the fourteenth wale W14 arranged on the outermost side of the tape main body portion 40 b forms the tape edge portion of the fastener tape 40 .

In this case, the base weave of the element mounting portion 40a is composed of a chain-like weaving yarn 41 of a 0-1/1-0 weave, a tricot weaving yarn 42 of a 1-0/1-2 weave, The first weft insertion yarn 43 of the 4-4/0-0 weave, the second weft insertion yarn 44 of the 0-0/3-3 weave, the warp insertion yarn 45 of the 0-0/1-1 weave become. In this case, the base weave of the tape body portion 40 b and the tape edge portion is woven with the tricot yarn 42 and the first weft insertion yarn 43 .

Still further, when weaving the zipper tape 40, on the fourteenth wale W14 forming the edge portion, not only the above-mentioned knitting structure but also a temporary chain-like knitting yarn of 0-1/1-0 weaving are prepared. 46. The temporary chain-like knitting yarn 46 is a water-soluble yarn, and can be melted by dipping in water after knitting the fastener tape 40 . The edge portion where the temporary chain knitting yarn 46 melts and no longer exists is formed as a base structure in which the stitches of the temporary chain knitting yarn 46 and the stitches of the tricot knitting yarn 42 remain. There is no knitting yarn in the course, and there is a base structure with a wide gap between adjacent stitches in the wale direction (the longitudinal direction of the fastener tape 40 ).

Thereby, the tape edge part (fourteenth wale W14) becomes the thickest base structure with a small number of yarns compared with other parts of the fastener tape 40. FIG. Therefore, when the fastener tape 40 is deformed into a curved form, the gaps between the stitches of the tape edge portion can be easily widened or narrowed, so the stretchability and flexibility of the fastener tape 40 are improved.

As mentioned above, with regard to the slide fastener of Patent Document 1, the fastener tape 40 has good elasticity and flexibility, and the elastic member is fixed to the fastener tape 40, so the fastener tape 40 can maintain a curved form, and can prevent the fastener tape 40 from being bent. The belt surface of the belt 40 produces corrugations and ridges in the form of waves.

Furthermore, since the stretchable member elastically deforms, when a pulling force in the longitudinal direction is applied to the fastener tape 40, the stretchable member can be stretched according to the deformation of the fastener tape 40, and then can be elastically restored when the pulling force is released. to the original shortened state. Therefore, for example, when the slide fastener of Patent Document 1 is sewn onto an article, even if the fastener tape 40 is sewn in a curved form deformed relative to the article, the tape surface hardly generates wrinkle-like wrinkles and bulges. part, can maintain a flat state.

In addition, as a slide fastener different from a slide fastener such as Patent Document 1 in which a continuous element row is attached by sewing after the fastener tape 40 is knitted, it is known, for example, to knit the fastener tape by sewing the fastener elements of the fastener tape. A braided zipper fixed by weaving a continuous chain element row into the mounting part. Such a braided zipper has good flexibility from the structural point of view, so it is particularly suitable for soft quilts (especially underwear) and the like.

Regarding such a braided slide fastener, for example, Japanese Patent No. 3396335 (Patent Document 2) discloses the following technology, that is, a plurality of chain knitting for fixing that is arranged on the element attachment portion of the fastener tape and fixes the continuous element row. Among the yarns, the chain knitting yarn for fixing on the meshing head side of the continuous element row is formed thicker than the other chain knitting yarn for fixing. As a result, the continuous element row can be stably and firmly attached to the element attachment portion of the fastener tape, and even if a strong force acts on the meshing state of the continuous element row, it is possible to prevent the continuous element row from being meshed. split.

Patent Document 1: Japanese Patent Laid-Open No. 2008-93210

Patent Document 2: Japanese Patent No. 3396335

Regarding the braided slide fastener, in order to improve the attachment of the continuous element row to the element attachment portion of the fastener tape, the improvement of the knit structure and the like have been performed on the element attachment portion of the fastener tape as in the above-mentioned Patent Document 2. However, in the knitting slide fastener, positive improvement has not been made so far about the tape portion other than the element attaching portion of the fastener tape.

On the other hand, in recent years, applications of knitted slide fasteners have been expanded to soft quilts and the like, and accordingly, higher stretchability and softness of knitted slide fasteners themselves have been desired.

In addition, when attaching the knitted slide fastener to covered products such as quilts, for example, the knitted slide fastener may be attached to a bent portion of the covered product. At this time, when the curvature of the curved portion of the covered product is large due to the design of the covered product, etc., if the woven slide fastener is attached to the curved portion, the fastener tape of the woven slide fastener will stand upright with respect to the continuous element row. Way warping or corrugated wrinkles are formed on the tape surface of the fastener tape, so there is a problem that the appearance of the produced coated product is reduced.

Contents of the invention

The present invention is made in view of the above-mentioned existing problems, and its specific purpose is to provide a kind of braided zipper fastener stringer, the stretchability and softness of its zipper tape are improved, and have good appearance quality, and, in this When the woven fastener tape is attached to a covered product, it is possible to prevent the fastener tape from warping and from forming wrinkles on the tape surface of the fastener tape.

In order to achieve the above object, the woven zipper stringer tape provided by the present invention, as its basic structure, knits a fixed coil-shaped or zigzag continuous thread while weaving the zipper tape on the fastener element installation part of the warp-knitted zipper tape. The warp-knitted zipper tape has a main body part and the element installation part formed at the first side edge of the main body part. The most important feature of the woven zipper chain tape is , the belt main body has knitting yarns forming stitches and connecting adjacent courses, and at least tricot knitting yarns arranged as the knitting yarns throughout the belt main body are disposed on the belt main body. ; the first weft insertion yarn running in a zigzag pattern within the range of two or more adjacent wales of the tape main body; The second weft insertion yarn running zigzag within the range, the outermost wale is arranged on the side of the belt main body closest to the second side edge, and the outermost wale is arranged every A course not having a knitting yarn is arranged every other course, and weft yarns are alternately inserted into the first weft insertion yarn and the second weft insertion yarn in the wale direction.

In the braided fastener stringer of the present invention, it is preferable that: the base chain-like braided yarn forming the base structure of the element attachment portion is disposed on the element attachment portion; The third weft insertion yarn running in a zigzag pattern within the range of two or more wales including the wale, and a part of the base chain weaving yarn is used as a fixing for fixing the continuous chain element row Chain braided yarn.

In this case, it is preferable that the fourth weft insertion yarn is arranged on the wale closest to the side edge side opposite to the tape arranged on the element attachment portion and the wale adjacent to the wale, The fourth weft insertion yarn zigzags and intersects with the third weft insertion yarn between courses to stabilize the position of the base chain weaving yarn. In addition, it is preferable to use a sliver harder than each constituent sliver constituting the belt body portion for the fixing chain knitting yarn.

Furthermore, in the woven fastener stringer of the present invention, it is preferable to use a yarn having a larger number of filaments than the sliver constituting the fixing chain-like knitting yarn for each constituent yarn constituting the tape main body portion. multi-filament yarn. Alternatively, it is preferable that the cross-sectional area of the entirety of the filaments constituting each sliver constituting the belt body portion is set smaller than the cross-sectional area of the entirety of the filaments constituting the sliver of the fixing chain knitting yarn.

The effect of the invention

The knitted fastener stringer tape of the present invention has a knitting yarn that forms stitches and connects adjacent courses in the tape main body portion of the warp-knitted fastener tape. In addition, the belt main body has at least: a tricot yarn arranged as a knitting yarn over the entire belt main body; The first weft insertion yarn; the second weft insertion yarn running in a zigzag pattern within the range of two or more wales including the outermost wale of the tape body portion.

Further, in the outermost wale of the tape main body portion, a course not having a knitting yarn is arranged every other course, and the weft yarn is alternately inserted into the first weft insertion in the wale direction (tape length direction). yarn and the second weft insertion yarn. In addition, the knitting yarn means the yarn which forms a stitch in at least one wale of a fastener tape, and is connected with the adjacent course.

In the knitted fastener stringer of the present invention, in the knitting structure, on the outermost wale of the tape body part, courses not having a knitting yarn are arranged every other course, in other words, alternately arranged Since the course of stitches and the course without stitches are formed by the tricot yarn, the interval of stitches on the outermost wale can be easily enlarged or reduced. Thereby, it is possible to easily bend the fastener tape, in particular, to easily bend the fastener tape in the horizontal direction with respect to the tape surface. Therefore, the stretchability and flexibility of the woven fastener stringer can be greatly improved.

Therefore, the woven fastener stringer of the present invention, for example, can be easily attached to a curved portion of a covered product such as clothing, and when mounted on the curved portion, can prevent the fastener tape from standing against the continuous element row. It can also prevent the formation of corrugated wrinkles on the tape surface of the fastener tape. Therefore, even when the knitted fastener stringer of the present invention is attached to a covered product, it is possible to prevent the appearance of the covered product from deteriorating.

On the other hand, the above-mentioned Patent Document 1 sews the continuous element row after the fastener tape is woven, so it does not relate to the knitted fastener stringer tape as in the present invention, but in the fastener tape of the Patent Document 1, in order to improve the In the outermost wales of the tape main body, courses in which stitches are formed by tricot yarn and courses without stitches are alternately arranged in order to improve the stretchability and flexibility. Further, on the outermost wale, a weft insertion yarn is inserted into a course forming a stitch. Therefore, in the fastener tape of Patent Document 1, a wide gap is formed between adjacent stitches in the outermost wale.

However, as in the above-mentioned Patent Document 1, in the case where a wide gap is formed between each stitch on the outermost wale, the appearance of the tape outer edge of the fastener tape is different from that of a normal fastener tape (that is, in the In the outermost wale, the fastener tape in which the stitches are formed in each course tends to give a zigzag appearance, so there is a problem that the appearance quality of the product deteriorates. In addition, in this case, there is also a problem that the strength of the outermost edge of the fastener tape is lowered, and the yarn is likely to be unraveled.

In contrast, in the knitted fastener stringer of the present invention, the first weft insertion yarn and the second weft insertion yarn are alternately weft-inserted in the wale direction in the outermost wale of the tape main body. That is, in the present invention, the weft yarn is inserted into the first weft insertion yarn or the second weft insertion yarn in a folded-back manner on the course in which the stitch of the tricot yarn is formed on the outermost wale, and The second weft insertion yarn or the first weft insertion yarn is also folded back into the course without a stitch on the wale.

Therefore, in the woven fastener stringer of the present invention, unlike the fastener tape of Patent Document 1, the outer edge of the tape does not give a jagged appearance, and the outer edge of the tape can be observed to be in a straight state. Therefore, the appearance quality of the woven zipper tooth chain tape can be improved. Moreover, in the present invention, the second weft insertion yarn runs zigzag in the range of two or more wales including the outermost wale, so that the strength of the belt outer edge portion can be improved, It is possible to prevent the yarn from being unraveled at the outer edge of the belt.

In such a woven fastener stringer of the present invention, the element attachment portion is provided with: a base chain-shaped knitting yarn forming the base structure of the element attachment portion; The third weft insertion yarn running in a zigzag pattern within the range of two or more wales including one row, and a part of the above-mentioned base chain knitting yarn is used as a chain knitting yarn for fixing the continuous chain element row . Thereby, while weaving the fastener tape, the continuous element row can be firmly knitted and fixed to the element attachment portion, and the base structure of the element attachment portion can be stabilized.

In this case, the fourth weft inserting yarn is arranged on the wale that is arranged on the side closest to the tape opposite side edge of the element attachment portion and on the wale adjacent to the wale, and the fourth weft insertion yarn is arranged on the wale. The insertion yarn runs zigzag and intersects with the third weft insertion yarn between the courses to stabilize the position of the base chain knitting yarn, so that the position of the fixing chain knitting yarn can be stabilized, thereby enabling The continuous chain element row is reliably fixed at the specified position. More specifically, the third weft insertion yarn and the fourth weft insertion yarn can prevent the chain knitting yarn for fixing the second wale from being misaligned in the direction of the first wale or the third wale. , because of the fourth weft insertion yarn, the fixing chain knitting yarn of the second wale will not be misaligned in the direction of the third wale, thereby not approaching the fixing chain knitting of the third wale Therefore, the element row can be stably fixed to the second wale and the third wale in the width direction. In addition, the second wale has the function of restricting the distance between two adjacent meshing heads in the element row by the fixing chain knitting yarn of the second wale when the element row is meshed and separated. If it is too large, since the fixing chain knitting yarn of the second wale will not be misaligned, the engagement and separation can be maintained for a long period of time, and the slidability accompanying this operation can also be stabilized for a long period of time.

In addition, by using a sliver harder than each constituent sliver constituting the belt main body portion for the chain knitting yarn for fixing, the fixation of the continuous element row can be made more stable. On the other hand, since each constituent yarn constituting the belt main body is softer than the fixing chain knitting yarn, the flexibility of the belt main body can be further improved.

Furthermore, in the woven fastener stringer of the present invention, multi-filament yarns having a larger number of filaments than the yarns constituting the chain-shaped knitting yarn for fixing are used for each constituent yarn constituting the tape main body portion. Yarn, or the cross-sectional area of the entirety of the filaments constituting the sliver constituting the belt body part is set to be smaller than the cross-sectional area of the entirety of the filaments constituting the sliver of the chain-like braiding yarn for fixing, thereby enabling more Effectively improve the flexibility of the belt main body.

Detailed ways

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, this invention is not limited to embodiment described below at all. Various changes can be made as long as it has substantially the same structure as the present invention and achieves the same effect.

For example, the continuous element row of the fastener stringer described in the following embodiments is formed by forming a single filament into a coil shape, but the present invention is not limited thereto, and may be formed by forming a single filament into a coil shape. Serrated and formed.

Fig. 1 is a front view showing a slide fastener constructed using the knitted fastener stringer of the present invention. In addition, Fig. 2 and Fig. 3 show the knitting structure of the zipper tape before the reinforcing chain knitting yarn in the woven fastener stringer is melted, and Fig. 5 and Fig. 6 show the knitting structure of the zipper tape after the reinforcing chain knitting yarn is melted. organize.

In addition, in the following description, the front-back direction means the longitudinal direction of the fastener tape in the knitted fastener stringer, the left-right direction means the belt width direction of the tape, and the front-back direction means the direction orthogonal to the tape surface of the fastener tape.

The slide fastener 1 described in this embodiment has: a pair of left and right knitted fastener stringers 10 woven and fixed with a continuous element row 12 ; , Separate slider 5. At this time, as the said slider 5, the same thing as the slider conventionally used normally is used.

The left and right pairs of said knitted fastener stringers 10 each have: the knitted fastener tape 11; and the continuous element line 12 which is knitted and fixed to the said fastener tape 11 simultaneously with the knitted fastener tape 11.

The continuous element row 12 is formed by pressing a single filament made of synthetic resin such as polyamide or polyester at constant intervals by punching to form the engaging head 12a, and then winding it into a coil shape. This continuous element row 12 is knit and fixed while knitting the fastener tape 11 so that the engaging head 12a protrudes from the tape-opposing side edge of the fastener tape 11 .

Moreover, the front stopper 13 is respectively fixed to the front end (upper end) of each continuous element row 12, and one back stopper 14 is fixed to the rear end (lower end) of the continuous fastener element row 12. As shown in FIG. Thereby, it can prevent that the slider 5 is pulled out from the front end and the rear end of the continuous element row 12. As shown in FIG. Furthermore, in the present invention, instead of the above-mentioned rear stopper 14, an opener having an insertion tube and a seat tube may also be fixed.

In the present embodiment, the above-mentioned fastener tape 11 has a tape main body portion 11a and an element attachment portion 11b formed on one side edge (first side edge) of the tape main body portion 11a and knitted with a continuous Chain tooth column 12. As shown in FIG. 2 , the fastener tape 11 is composed of a warp-knitted tape knitted with a plurality of weaving yarns and a plurality of weft insertion yarns.

In addition, in the fastener tape 11, the wale arranged on the side (inner side) closest to the tape opposite side edge of the left and right fastener tape 11 is set as the first wale W1, and the first wale W1 to the third wale The element attachment part 11b is formed in the range of the wale W3, and the tape main body part 11a is formed in the range of the other 4th wale W4 - the 13th wale W13. In addition, in this embodiment, the thirteenth wale W13 arrange|positioned at the outermost edge on the side closest to the other side edge (2nd side edge) of this belt main body part 11a forms a belt edge part.

The fastener tape 11 is knitted so as to have the knitting structure shown in FIGS. 2 and 3 at the time of its weaving.

To describe specifically, the knitting structure of the tape main body portion 11a is constituted using the following yarns: tricot yarns 20 (1-2/1 -0); the first weft insertion yarn 21 (4-4/0-0) that is arranged in the region of the belt main body 11a and runs zigzag within the range of 4 wales; The second weft insertion yarn 22 (0-0/3-3) running in a zigzag pattern within the three wales from the wale W11 to the thirteenth wale W13 on the outermost edge; only arranged in the outermost The water-soluble temporary chain knitting yarn 25 (0-1/1-0) in the thirteenth wale W13 of the edge; the reinforcing chains arranged on the fourth wale W4 to the sixth wale W6 Weaving yarn 26 (0-1/1-0).

In this case, the second weft insertion yarn 22 makes the running position opposite to each other in such a manner that the first weft insertion yarn 21 and the second weft insertion yarn 22 are alternately inserted in the thirteenth wale W13 of the outermost edge. The first weft insertion yarn 21 is shifted by one course and arranged. Therefore, the first weft insertion yarn 21 and the second weft insertion yarn 22 are arranged to intersect between the courses.

In addition, in order to weave the zipper tape 11, as a basic structure, the chain knitting yarn must be arranged on the thirteenth wale W13 on the outermost edge. Therefore, when weaving the zipper stringer 10, the water-soluble temporary chain The knitting yarn 25 is knitted in the thirteenth wale W13. In addition, when the provisional chain-like knitting yarn 25 is arranged on the outermost thirteenth wale W13, the fastener tape 11 is firmly formed, but the stretchability and flexibility of the fastener tape 11 are reduced. Therefore, in this embodiment, after knitting the knitted fastener stringer 10 as mentioned later, the temporary chain knitting yarn 25 is melt|dissolved, and the temporary chain knitting yarn 25 is removed from a knitting structure.

On the other hand, the knitting structure of the element attaching portion 11b is constituted using the base chain knitting yarn 27 (0-1/1-0) arranged on the first wale W1 to the third wale W3. ); arranged in the area from the first wale W1 to the fifth wale W5 and running in a zigzag pattern within the range of three wales including the first wale W1 to the third wale W3 The third weft insertion yarn 23 (3-3/0-0); the first weft insertion yarn 23 that runs in a zigzag pattern on the first and second wales W1, W2 and intersects with the third weft insertion yarn 23 between courses Four weft insertion yarns 24 (0-0/2-2). In addition, among the base chain knitting yarns 27 arranged on the first wale W1 to the third wale W3, the base chain knitting yarns arranged on the second wale W2 and the third wale W3 are 27 is used as the fixing chain knitting yarn 27a for fixing the continuous element row 12 .

In this embodiment, a water-soluble multi-filament yarn made of polyvinyl alcohol is used for the temporary chain-like knitting yarn 25, and nylon or polyester-based multi-filament yarn is used for other knitting yarns and weft insertion yarns. In addition, in the present invention, the material of each yarn is not particularly limited, and yarns made of other materials may also be used.

Furthermore, in this case, the tricot knitting yarn 20, the first weft insertion yarn 21, the second weft insertion yarn 22, and the reinforcing chain knitting yarn 26 arranged on the belt main body portion 11a are used more than those arranged on the chain. The chain-shaped knitting yarn 27a for fixing on the tooth attachment portion 11b is a soft multi-filament yarn (in other words, the chain-like knitting yarn 27a for fixing uses a softer multi-filament yarn than the tricot yarn 20 and the first weft yarn arranged on the belt main body 11a. inserting yarn 21, the second weft inserting yarn 22, and reinforcing chain weaving yarn 26 (hard multi-filament yarn).

For example, in the case of comparison using slivers having the same fineness, the tricot weaving yarn 20, the first weft insertion yarn 21, the second weft insertion yarn 22, and the reinforcing chain knitting yarn 26 are used per unit The number of filaments in cross-sectional area is a multi-filament yarn that is larger than the fixing chain-shaped knitting yarn 27a of the element attaching portion 11b. Alternatively, for the tricot yarn 20, the first weft insertion yarn 21, the second weft insertion yarn 22, and the chain knitting yarn 26 for reinforcement, the overall cross-sectional area of the filaments may be smaller than that of the chain knitting yarn 27a for fixing. multi-filament yarn.

As a specific example, when using a multi-filament yarn having a fineness of 167 dtex to 330 dtex and a number of filaments of 40 to less than 120 for the fixing chain knitting yarn 27a of the element attachment portion 11b, The tricot knitting yarn 20, the first weft insertion yarn 21, and the reinforcing chain knitting yarn 26 of the main body portion 11a are respectively used with a fineness of 84 dtex or more and 167 dtex or less, and a number of filaments of 120 or more and 160 or less. Multi-filament yarn.

In addition, in the case of counting the number of filaments, the multi-filament yarns are classified into slivers constituting the fastener stringer, and the circular cross section thereof is enlarged using, for example, an electron microscope. Thereby, the number of filaments can be counted for each constituent sliver. In addition, when measuring the cross-sectional area of the filament, the circular cross-section of the multi-filament yarn is similarly enlarged to enable the measurement.

In addition, as the second weft insertion yarn 22, a multi-filament yarn having a fineness of 167 dtex to 330 dtex and a filament count of 120 to 160 is used. Thereby, the continuous element row 12 can be firmly fixed to the element attachment part 11b by the chain knitting yarn 27a for fixation, and the belt main body part 11a can be formed flexibly.

And the knitted fastener stringer 10 knitted with the above-mentioned knitting structure implements thermosetting after knitting, and fixes the form. Furthermore, the obtained knitted fastener stringer 10 is immersed in water, and the water-soluble provisional chain-shaped knitting yarn 25 arrange|positioned on the thirteenth wale W13 of the outermost edge is melt|dissolved and removed. Thereby, the knitted fastener stringer 10 which has a knit structure as shown in FIG.5 and FIG.6 is obtained.

In the woven fastener stringer 10 of the present embodiment thus obtained, the tricot yarn 20 and the first weft insertion yarn 21 are arranged over the entire tape main body 11a, and the seventh wale W7 of the tape main body 11a is In the area from the thirteenth wale W13, there is no structure forming a stitch connecting adjacent courses on the same wale. On the other hand, the chain knitting yarn 26 for reinforcement is arrange|positioned only in the 4th wale W4 - the 6th wale W6 by the side of the element attaching part 11b in the tape main body part 11a. Therefore, the tape main body portion 11a of the fastener tape 11 can have improved stretchability and flexibility compared to, for example, a case where the chain-like braided yarn is arranged over the entire tape main body portion, and the tape main body portion 11a can be configured flexibly.

In addition, in the region of the seventh wale W7 to the thirteenth wale W13 in the tape main body portion 11a, two or more stitches are not formed for one stitch, so that the following effect can be obtained: The thickness of the fastener tape 11 in this region can be made thin, and the tape surface can be formed in a relatively flat state.

In addition, in this woven fastener stringer 10, in the thirteenth wale W13 which becomes the outermost edge of the tape main body part 11a, the course which does not have a knitting yarn is arrange|positioned every other course, in other words, a special The courses on the one end side (thirteenth wale W13 side) of the rico knitting yarn 20 are arranged every other course. In particular, when viewed from the knitting pattern of the fastener tape, courses in which stitches are formed by the tricot yarn 20 and courses without stitches are alternately arranged on the thirteenth wale W13.

In addition, as shown in FIG. 6 , one end side of the tricot yarn 20 arranged on the thirteenth wale W13 (the thirteenth wale W13 side), and the other end side of the tricot yarn 20 The side (twelfth wale W12 side) passes on the upper side of the second weft insertion yarn 22 . In addition, in the tricot yarn 20 arranged on the thirteenth wale W13, the weft weft arranged between the thirteenth wale W13 and the adjacent twelfth wale W12 is The yarn portion passes under the second weft insertion yarn 22.

As mentioned above, since the course not having the knitting yarn is arranged every other course on the thirteenth wale W13, for example, when the fastener tape 11 is subjected to an external force, etc., the stitches formed by the tricot yarn 20 will not be fixed. The space|interval expands and shrinks easily, and the stretchability and flexibility of the tape main body part 11a of the fastener tape 11 can be improved further. Therefore, for example, the fastener tape 11 can be easily bent with a desired curvature in the horizontal direction with respect to the tape surface.

Therefore, according to this woven fastener stringer 10, even when it attaches to the curved part of covered products, such as quilts, for example, it can attach easily according to the shape of the said curved part. Furthermore, when the knitted fastener stringer 10 is attached to this bent portion, it is possible to prevent the fastener tape 11 from warping so as to stand up with respect to the continuous element row 12 and to prevent the tape surface of the fastener tape 11 from being corrugated. of folds. Thereby, deterioration of the appearance of the covered product to which the knitted fastener stringer 10 is attached can be prevented, and the good covered product of an appearance quality can be provided.

In addition, in this woven fastener stringer 10, on the thirteenth wale W13 at the outermost edge of the tape main body portion 11a, the first weft insertion yarn 21 and the second weft insertion yarn 22 are drawn in the wale direction. The weft yarns are inserted alternately.

Furthermore, in the woven fastener stringer 10 of the present embodiment, the element attaching portion 11b is formed of the base chain-shaped weaving yarn 27, the third weft insertion yarn 23, and the fourth weft insertion yarn 24, and the continuous element row 12 The base chain knitting yarn 27 arranged on the second wale W2 and the third wale W3 is fixed. Therefore, the continuous element row 12 can be stably knit in the element attachment part 11b at the time of knitting the fastener tape 11, and this continuous element row 12 can be firmly fixed.

In particular, in this element attachment portion 11b, the third weft insertion yarn 23 and the fourth weft insertion yarn 24 are inserted into the second wale W2 in the same course, so that the weft insertion yarn 23 and the fourth weft insertion yarn 24 are inserted in the same course. In the fastener stringer 10, the position of the fixing chain knitting yarn 27a arranged on the second wale W2 can be prevented from shifting in the course direction, and the fixing chain knitting yarn 27a can be stably held at a predetermined position. As a result, the fixed position of the continuous element row 12 with respect to the element attaching part 11b is also stabilized, and when the slide fastener 1 is comprised using this knitted fastener element string 10, desired sliding property of the slider 5 can be acquired stably.

Moreover, in the knitted fastener stringer 10 of this embodiment, the chain-shaped knitting yarn 26 for reinforcement is arrange|positioned in the area|region of the 4th wale W4 - the 6th wale W6 in the tape main body part 11a. The region where the reinforcing chain knitting yarn 26 is disposed becomes a region where the left and right flange portions (not shown) on the slider 5 may come into contact when the slide fastener 1 is configured as described in FIG. 1 . Therefore, by knitting the reinforcing chain knitting yarn 26 in the region of the fourth wale W4 to the sixth wale W6, the strength of the region can be increased, and the sliding of the slider 5 can be effectively prevented even if the slider 5 repeatedly slides. Belt 11 wear and tear and other adverse conditions.

In addition, in the present invention, for the knitted structure of the fastener stringer 10, at least the tricot yarn 20 and the first weft insertion yarn 21 arranged in the tape main body 11a in a zigzag shape are used in the tape main body 11a. The second weft insertion yarn 22 that zigzags in the range of two or more wales including the outermost wale is not particularly limited, and may be placed between the belt main body 11a and the fastener element. Other knitting yarns, weft insertion yarns, and the like are disposed on the attachment portion 11b.

Furthermore, the first weft insertion yarn 21 may not be arranged to run zigzag within the range of 4 wales as described above, but may be arranged within the range of 2 or 3 wales, or 5 or more The range of coil wales is configured to run in a zigzag pattern. In addition, similarly, the second weft insertion yarn 22 may be arranged so as to run in a zigzag pattern within the range of two wales or four or more wales including the outermost wale.
