  • the wales of the element mounting portion 22 (first wales W1, second wales W2, or third wales W3) and the wales of the tape body portion 21 (fourth wales W4, fifth wales W4) It has a first single satin knitting yarn 32a that alternately forms needle loops on W5 or a sixth wale W6), and a second single satin knitting yarn 32b that forms needle loops only on the wales of the tape body 21.
  • the sinker loop of the first single satin knitting yarn 32a is arranged across the boundary portion 23 of the tape main body portion 21 and the element mounting portion 22.
  • the boundary portion 23 between the tape main body portion 21 and the element mounting portion 22 is located between the third wale W3 and the fourth wale W4. That is, in the present embodiment, the sinker loop of the three first single satin knitting yarns 32a and the two weft insertion yarns 33 form the boundary portion 23 between the tape main body portion 21 and the element mounting portion 22 between the courses. It is arranged to cross. Further, in this case, the sinker loop of the first single satin knitting yarn 32a and the two weft insertion yarns 33 intersect each course as described later. As a result, the tape strength of the boundary portion 23 between the tape main body portion 21 and the element mounting portion 22 and the tape strength of the portion in the vicinity of the boundary portion 23 are increased.
  • the first single satin knitting yarn 32a that crosses the boundary portion 23 is formed thicker than the second single satin knitting yarn 32b.
  • the first single satin knitting yarn 32a has a thickness of 1.1 times or more and 2.0 times or less, preferably 1.4 times or more and 1.6 times or less the thickness of the second single satin knitting yarn 32b.
  • the first single satin knitting yarn 32a of the present embodiment has a thickness of 167 decitex
  • the second single satin knitting yarn 32b has a thickness of 110 decitex.
  • the portion where the tape strength is increased by the first single satin knitting yarn 32a is a portion where the flange portion of the slider 40 easily comes into contact with the slide fastener 1. Therefore, since the fastener tape 20 includes the first single satin knitting yarn 32a and has high tape strength as described above, the fastener tape 20 is damaged even if the sliding operation of the slider 40 is repeated. It can be difficult.
  • a plurality of weft insertion threads 33 are inserted into the entire first wales W1 to 14th wales W14.
  • Each weft insertion thread 33 is inserted in a zigzag shape over 3 wales.
  • the weft insertion thread 33 of the present embodiment is inserted in a direction intersecting the sinker loop of the single satin knitting thread 32 between each course.
  • the direction in which the weft insertion yarn 33 is folded back by the needle loop and the sinker loop of the single satin knitting yarn 32 are from the needle loop.
  • the extending direction means that the direction of extension is deviated from the direction of the wales by one course.
  • the weft insertion thread 33a arranged closest to the inner edge of the tape folded back by the first wale W1 is formed thinner than the other weft insertion threads 33 arranged on the fastener tape 20.
  • the weft insertion yarn 33a can weaken the force (tension) that pulls the thick chain knitting yarn 31a arranged on the first wale W1 in the direction of approaching the tape main body portion 21. Therefore, it becomes easy to secure a large dimension in the tape width direction from the boundary portion 23 to the inner edge of the tape of the element mounting portion 22, and as a result, the gap formed between the left and right fastener tapes 20 can be reduced.
  • the fixing chain knitting yarn 34 has a knitting structure of (0-0 / 0-1 / 1-1 / 1-0) by the front row F of the warp knitting machine, and the second wales of the element mounting portion 22. It is woven into W2 and the third wales W3. That is, the ground structure of the fastener tape 20 and the knitting portion of the chain knitting yarn 34 for fixing are knitted in separate single structures by the back row B and the front row F of the warp knitting machine. As a result, the flexibility of the fastener tape 20 can be increased, the weight of the braided fastener stringer 10 can be reduced, and the productivity can be improved.
  • the upper leg portion and the lower leg portion of the fastener element 12 are inserted so as to be sandwiched between the ground structure of the element mounting portion 22 and the chain knitting yarn 34 for fixing.
  • the sinker loop of the fixing chain knitting yarn 34 intersects and is entangled with the ground structure of the element mounting portion 22.

Therefore, in the manufactured braided fastener stringer 10, the second fixing chain knitting yarn 34b is formed by two yarns having a thickness of 220 decitex. Regarding the first fixing chain knitting yarn 34a of the present embodiment, the knitting process of the braided fastener stringer 10 is performed without including auxiliary fibers.
  • the force for pressing the fastener element 12 with the second fixing chain knitting yarn 34b is applied.
  • the force of pressing the fastener element 12 with the first fixing chain knitting yarn 34a can be weakened.
  • the fastener tape 20 is compared with the case where the knitting process is performed without including the fibers to be removed in, for example, the first fixing chain knitting yarn 34a and the second fixing chain knitting yarn 34b. It becomes easy to allow the movement of each fastener element 12 woven into.
  • the flexibility of the braided fastener stringer 10 can be increased more effectively, and the slidability of the slider 40 in the slide fastener 1 can be further improved.
  • the fastener element 12 can be stably fixed to the element mounting portion 22.
  • the meshing strength (horizontal pulling strength) of the fastener chain and the meshing strength (bending strength) when the fastener chain is bent in the front and back directions of the tape can be appropriately secured.
  • a warp knitting process for knitting the braided fastener stringer 10 is performed using a warp knitting machine provided with two rows of needle beds composed of a back row B and a front row F.
  • the needle loop of the fixing chain knitting yarn 34 is formed by the front row F, and the fixing chain knitting yarn is formed.
  • the 34 sinker loops are entwined with the ground structure of the fastener tape 20.
  • the fastener element 12 formed from the monofilament is inserted between the ground structure of the fastener tape 20 and the fixing chain knitting yarn 34.
