  • the stringer attachment edge 91 and the fastener stringer 21 are sewn together to form the sewn portion 12 in a lockstitch sewing process using the sewing machine.
  • the sewn portion 12 extends straight in the front-and-rear direction of the fastener tape 22 .
  • the sewn portion 12 fixes the fastener stringer 21 to the stringer attachment edge 91 (second strip portion 97 ) of the cloth piece 90 .
  • a part of the sewn portion 12 is disposed between the first strip portion 95 and the second strip portion 97 of the double-layer portion 94 .
  • the sewn portion 12 of Embodiment 4 is separated outward in the left-and-right direction (toward the inner region of the tape) from the fastener elements 23 .
  • the stringer attachment edge 91 is bent at the sewn portion 12 such that the first strip portion 95 and the second strip portion 97 overlap in the upper-and-lower direction to form the double-layer portion 94 . Therefore, the bent portion 96 is formed at a position close to the sewn portion 12 .
  • a separation distance D 3 between the sewn portion 12 and the fin portion 23 b of each fastener element 23 in the left-and-right direction is preferably 3.0 mm or less. More preferably, the separation distance D 3 is 2.0 mm or less, or 1.0 mm or less. The separation distance D 3 is preferably 0.5 mm or more. In other words, the separation distance D 3 is preferably 60% or less of the width of each fastener element 23 (here, the width excluding the width of the first and second fin portions) in the left-and-right direction. More preferably, the separation distance D 3 is 40% or less, or 20% or less, of the width of each fastener element 23 excluding the fin portions in the left-and-right direction.
  • the separation distance D 3 is preferably 10% or more of the width of each fastener element 23 excluding the fin portions in the left-and-right direction.
  • Embodiment 4 unlike Embodiments 1 to 3, no flap is formed in the region between the position of the sewn portion 12 and the position of the bent portion 96 .
  • the separation distance D 3 is small, a waterproof region is provided between the sewn portion 12 and the fastener elements 23 .
  • the sewing needle does not easily come into contact with the fastener elements 23 during formation of the sewn portion 12 using the sewing machine.
  • the fastener tape 22 can be smoothly and reliably sewn onto the stringer attachment edge 91 of the cloth piece 90 in the sewing process.
  • the sewn portion 12 is disposed away from the fastener elements 23 in the left-and-right direction.
  • the separation distance D3 between the sewn portion 12 and the fastener elements 23 is as small as 3.0 mm or less, the fastener tape 22 is not easily visible through the gap between the double-layer portion 94 and the fastener elements 23 . Accordingly, adverse effects on, for example, the design and appearance quality of the clothing item due to the exposure of the fastener tape 22 can be eliminated or reduced.
  • a rain test described below was performed to confirm that a waterproof region was formed between the sewn portion 12 and the fastener elements 23 .
  • the rain test was conducted under rain conditions in accordance with AATCC35 ( 24 in, 2 min).
  • AATCC35 24 in, 2 min.
  • a leakage prevention tape was applied to the front surfaces of the fastener elements 23 in the test.
  • the water permeability of the waterproof region was confirmed to be less than 0.1 g in each of Embodiments 1 to 4.
  • the present invention is not limited to Embodiments 1 to 4 described above, and various changes are possible as long as a configuration substantially the same as that of the present invention is provided and similar operational effects are obtained.
  • the slide fastener 20 and the fastener stringers 21 are formed by forming the independently shaped fastener elements 23 on the fastener tapes 22 by injection molding using a synthetic resin.
  • the slide fastener and the fastener stringers may be formed by forming independently shaped fastener elements made of metal on the fastener tapes instead of the fastener elements 23 made of a synthetic resin.
  • the slide fastener-attached clothing item is at least waterproof in Embodiments 1 to 4, it is not necessary that the slide fastener-attached clothing item be waterproof in the present invention.
  • the clothing item is described as a typical example of a product to which the slide fastener is attached in the embodiments, the slide fastener-attached product is not limited to a clothing item in the present invention.
  • the slide fastener-attached product according to the present invention may be various products including apparel products other than clothing items, daily products, such as shoes and bags, industrial materials, and various seat products for automobiles, trains, and aircraft.
