  • a hidden type slide fastener hereafter referred to as a hidden slide fastener
  • a hidden slide fastener that has the ability to conceal the fastener elements by making them invisible (or difficult to see) from the outer surface of the slide fastener when the left and right element rows are interlocked with each other.
  • Patent Document 1 JP Patent Publication 2008-119076 (Patent Document 1) describes a fastener stringer used in a hidden slide fastener, which includes a fastener tape with a woven structure and a woven fastener stringer having multiple fastener elements that are woven into and fixed to a part of the fastener tape when the fastener tape is woven.
  • the element attachment portion of the fastener tape is provided with the following warp threads in the weave: upper fixing warp threads running in the warp direction on the outer surface of the upper leg of each fastener element, lower fixing warp threads running in the warp direction on the outer surface of the lower leg of each fastener element, and fastening warp threads running in the warp direction so as to alternately straddle the upper and lower leg portions of the fastener element.
  • the total fineness of the lower fixing warp threads running closer to the meshing head of the fastener element than the fastening warp threads is set to be larger than the total fineness of the upper fixing warp threads running closer to the meshing head than the fastening warp threads.
  • the lower fixing warp threads running on the interlocking head side of the fastener elements are arranged more densely than the tightening warp threads. Therefore, when a hidden slide fastener is manufactured using the woven fastener stringer of Patent Document 1, when the left and right element rows of the hidden slide fastener are interlocked and a lateral pulling force is applied to pull the left and right fastener tapes from the left and right outer sides in the width direction, gaps are less likely to occur between the left and right fastener tapes. As a result, the concealment of the hidden slide fastener can be improved.

  • the woven fastener stringer 20 and the cover member 6 are placed on the needle plate of the sewing machine with the tape body 22 of the fastener tape 21 and the cover member 6 overlapping, and are held down by the sewing machine foot.
  • the fastener tape 21, which is folded into a U-shape is opened so that the angle between the element attachment portion 24 and the tape body 22 becomes larger, and the element row 50, together with the element attachment portion 24 of the fastener tape 21, is introduced into the element guide groove formed in the sewing machine foot (not shown).
  • the sewing machine is operated to intermittently feed the woven fastener stringer 20 and the cover member 6 along the feed direction of the sewing machine.
  • the element row 50 and the element attachment portion 24 are continuously guided into the element guide groove of the sewing machine foot, so that the woven fastener stringer 20 is fed under the sewing machine foot while opening the fastener tape 21, which is bent into a U-shape.
  • the sewing machine needle is repeatedly raised and lowered relative to the woven zipper stringer 20 and the upholstery member 6 held down by the sewing machine foot.
  • the sewing machine needle with the sewing thread threaded therethrough is pierced at regular intervals through the woven zipper stringer 20 and the upholstery member 6 in a position close to the thick second warp thread 32 of the fastener tape 21, preferably in a position between the two second warp threads 32.
  • the sewing thread of the sewing machine forms a sewn portion 60 continuously along the length of the fastener tape 21, and the sewn portion 60 can be used to sew the woven zipper stringer 20 to the upholstery member 6 and secure it firmly.
  • one of the woven zipper stringers 20 is sewn to the upholstery member 6 of the seat cover 1.
  • the other woven fastener stringer 20 of the hidden slide fastener 10 and another cover member 6 of the seat cover 1 are sewn to the cover member 6 of the seat cover 1 in the same manner as described above, so that the other woven fastener stringer 20 is sewn to the cover member 6 of the seat cover 1 and firmly fixed.
  • the method and means for sewing the woven fastener stringer to the fastener receiving member such as the skin member 6 are not particularly limited, and the woven fastener stringer can be sewn to the fastener receiving member using various conventionally known methods and means.
  • a seat cover 1 can be obtained with left and right woven fastener stringers 20 sewn to it.
  • a slider 13 is attached to the left and right woven fastener stringers 20 sewn to the seat cover 1, and a first fastener 11 and a second fastener 12 are provided to manufacture an automobile seat cover 1 with a hidden slide fastener 10.
  • the slider 13, the first fastener 11, and the second fastener 12 are attached to the left and right woven fastener stringers 20 to produce the hidden slide fastener 10, and then the left and right woven fastener stringers 20 of the obtained hidden slide fastener 10 are sewn to the seat cover 1 to produce the seat cover 1 with the hidden slide fastener 10.
  • the left and right cover members 6 of the seat cover 1 are butted against each other when the left and right element rows 50 are interlocked, as shown in FIG. 3.
  • the two thick second warp threads 32 woven into the left and right woven fastener stringers 20 are arranged in two positions, one above and one below the sewn portion 60, close to the sewn portion 60.
  • This allows the left and right cover members 6 to be stably butted together, and also allows the cover members 6 to be stably maintained in a butted state.
  • the left and right woven fastener stringers 20 (particularly the left and right element rows 50) in the interlocking state can be concealed by the left and right cover members 6 so that they cannot be seen from the outer surface side of the seat cover 1 (upper side in Figure 3).
  • the left and right sewing parts 60 that sew the woven fastener stringer 20 and the cover member 6 together are provided so as to penetrate the fastener tape 21 at positions close to each of the two second warp threads 32. Furthermore, each sewing part 60 is provided so as to penetrate the respective fastener tape 21 at a position between the two second warp threads 32.
  • the sewn portion 60 being located in close proximity to the second warp thread 32 means that the sewn portion 60 is located in a position relative to the second warp thread 32 such that the number of warp threads 30 of the fastener tape 21 disposed between the sewn portion 60 and the second warp thread 32 is four or less, preferably two or less.
  • the stitching portion 60 is provided at a position where the distance (minimum distance) between the stitching portion 60 and the second warp thread 32 arranged on the side edge adjacent to the tape fold portion 23 of the element attachment portion 24 is 2 mm or less, preferably 1 mm or less, when viewed in a cross section perpendicular to the longitudinal direction of the fastener tape 21.
  • the stitching portion 60 is provided at a position where the distance (minimum distance) between the stitching portion 60 and the second warp thread 32 arranged on the side edge adjacent to the tape fold portion 23 of the tape body portion 22 is 3 mm or less, preferably 1 mm or less, when viewed in a cross section perpendicular to the longitudinal direction of the fastener tape 21.
  • the two thick second warp threads 32 arranged on each fastener tape 21 can hold down the sewn portion 60.
  • the thick second warp threads 32 (particularly the lower second warp threads 32 arranged on the element mounting portion 24) can make it difficult for the tape folding portions 23 of the left and right fastener tapes 21 to move outward in the left-right direction. This restricts or suppresses the left and right upholstery members 6 from moving outward in the left-right direction, making it easier to maintain the state in which the left and right upholstery members 6 are butted together.
  • each second warp thread 32 of the fastener tape 21 is formed thicker than the first warp threads 31.
  • each second warp thread 32 of this embodiment 1 is formed so that the area of the cross section perpendicular to the length direction of the second warp threads 32 is large enough to prevent or suppress the position of the second warp threads 32 from shifting in the weft direction when the fastener tape 21 is subjected to a strong lateral pulling force as described above.
  • the fastener-equipped seat cover 1 of this embodiment even if the density of the weft threads 35 in the length direction of the fastener tape 21 is small, as in a conventional woven fastener stringer, the thick second warp threads 32 are arranged close to the sewn portion 60, and thus it is possible to effectively prevent or suppress the displacement of the first warp threads 31 and the second warp threads 32 in the weft direction when a strong lateral pulling force is applied to the left and right skin members 6.
  • the second warp threads 32 are arranged adjacent to the top and bottom of the sewn portion 60, so that it is possible to effectively prevent misalignment of the first warp threads 31 arranged on the tape body portion 22 of the fastener tape 21 and the first warp threads 31 arranged on the element attachment portion 24.
  • two thick second warp threads 32 are arranged on each of the left and right fastener tapes 21 (particularly near the tape folds 23 of the fastener tapes 21), so that a relatively long distance can be secured in the vertical direction from the outer surfaces (upper surfaces) exposed to the outside of the left and right skin members 6 to the positions of the meshed left and right element rows 50.
  • the fastener seat cover 1 of this embodiment 1 has excellent concealment properties because the interlocking left and right element rows 50 and fastener tape 21 can be covered and hidden by the left and right skin members 6 to make them invisible (or difficult to see) even when a strong lateral pulling force is applied to the left and right skin members 6. Therefore, by using the fastener seat cover 1 of this embodiment 1, it is possible to effectively prevent the appearance quality of the seat cover 1, and further the appearance quality of the seat to which the seat cover 1 is attached, from being reduced due to the exposure of the element rows 50.
  • the second warp thread 32 which is thicker than the first warp thread 31, is arranged in the warp thread 30 that is arranged closest to the tape folding portion 23 among the multiple warp threads 30 that form the tape main body portion 22, as described above, and in one of the three upper fixing warp threads 41 that are arranged on the meshing head portion 52 side of the positioning warp thread 44 in the element mounting portion 24.
  • the position at which the second warp threads 32 are arranged is not particularly limited as long as it is close to the sewn portion 60, and can be changed depending on the size and use of the slide fastener.
  • Figure 4 shows a woven fastener stringer 20c according to a modified example in which the position of the second warp threads 32 arranged in the element attachment portion 24 is changed from that of the fastener stringer 20 of Example 1.
  • the second warp thread 32 which is thicker than the first warp thread 31, is arranged on the side edge adjacent to the tape fold 23 of the tape body 22 and on the side edge adjacent to the tape fold 23 of the element mounting part 24.
  • the second warp thread 32 of the element mounting part 24 is used as one of the two upper fixing warp threads 41 arranged between the positioning warp thread 44 closest to the engagement head 52 and the fastening warp thread 43 adjacent to the positioning warp thread 44.
  • the two thick second warp threads 32 are arranged close to the sewn portion 60, so that when a strong lateral pulling force is applied to the left and right skin members 6, it is possible to prevent or suppress the first warp threads 31 and the second warp threads 32 from shifting in the weft direction. Therefore, it is possible to effectively prevent the formation of a gap between the left and right skin members 6 that would expose the element row 50 and the fastener tape 21, and also to make it difficult for the element row 50 to be exposed between the left and right fastener tapes 21.
  • the second warp thread 32 of the tape body 22 is used as the warp thread 30 that is arranged closest to the tape fold 23 among the multiple warp threads 30 that form the tape body 22, as in the woven fastener stringer 20 of the first embodiment described above.
  • the second warp thread may be used as the warp thread that is arranged at the tape fold, for example, or may be used as the warp thread that is second or third closest to the tape fold among the multiple warp threads that form the tape body.
  • Fig. 5 is a cross-sectional view showing a concealed slide fastener according to the present embodiment 2.
  • Fig. 6 is a cross-sectional view showing a main part of a seat cover manufactured by sewing the concealed slide fastener to a cover member in the present embodiment 2.
  • parts or components that are substantially the same as those of the hidden slide fastener 10 and zippered seat cover 1 of the aforementioned embodiment 1 will be represented by the same symbols and their descriptions will be omitted.
  • the hidden slide fastener 10a of this embodiment 2 has at least a pair of left and right hidden woven fastener stringers 20a and sliders (not shown) attached to the element rows 50 of the left and right woven fastener stringers 20a.
  • the sliders used in this embodiment 2 are formed substantially similarly to the slider 13 described in the above-mentioned embodiment 1.
  • a dedicated opening and closing member formed to be attachable and detachable to the left and right element rows 50 may be used instead of the sliders.
  • each of the left and right woven fastener stringers 20a has a fastener tape 21a with a woven structure formed by multiple warp threads 30 and weft threads 35, and multiple fastener elements 51 that are woven into and fixed to a portion of the fastener tape 21a.
  • the warp threads 30 forming the fastener tape 21a have a plurality of first warp threads 31 each having the same thickness, and one second warp thread 32 thicker than the first warp thread 31, and the one second warp thread 32 is arranged on the side edge portion adjacent to the tape fold portion 23 of the element attachment portion 24 of the fastener tape 21a.
  • the woven fastener stringer 20a of this embodiment 2 is formed by changing the second warp threads 32 arranged in the tape body 22 of the fastener tape 21 to first warp threads 31 that are thinner than the second warp threads 32, as compared to the hidden slide fastener 10 of the above-mentioned embodiment 1.
  • the number of thick second warp threads 32 used in the fastener tape 21a of this embodiment 2 is only one, not two as in the fastener tape 21 of the above-mentioned embodiment 1.
  • the woven fastener stringer 20a of this embodiment 2 is formed in the same manner as the woven fastener stringer 20 of the above-mentioned embodiment 1, except that the second warp threads 32 arranged in the tape body 22 of the fastener tape 21a are changed to the first warp threads 31.
  • the hidden slide fastener 10a is produced by sewing the woven fastener stringer 20a to the cover member 7 of the seat cover 2 using a sewing machine, in the same manner as in the above-mentioned embodiment 1, to produce the zippered seat cover 2 shown in FIG. 6.
  • the left and right sewing parts 60 that sew the woven fastener stringer 20a and the cover member 7 together are arranged above the second warp threads 32 arranged in the element attachment part 24 (in other words, at a position closer to the tape body part 22 of the fastener tape 21a than the second warp threads 32).
  • the position of the second warp thread 32 and the positions of the multiple first warp threads 31 arranged in the element mounting portion 24 can be effectively prevented or suppressed from shifting in the weft direction. This makes it possible to prevent or suppress the formation of gaps between the left and right skin members 7 that expose the element row 50 and fastener tape 21a due to the positional shift of the warp thread 30.
  • the fastener seat cover 2 of the second embodiment has excellent concealment properties.
  • FIG. 7 is a cross-sectional view showing a concealed slide fastener according to this embodiment 3.
  • FIG. 8 is a cross-sectional view showing a main part of a seat cover produced by sewing the concealed slide fastener to a cover member according to this embodiment 3.
  • the hidden slide fastener 10b of this embodiment 3 has at least a pair of left and right hidden type woven fastener stringers 20b and sliders (not shown) attached to the element rows 50 of the left and right woven fastener stringers 20b.
  • Each of the left and right woven fastener stringers 20b has a fastener tape 21b with a woven structure formed by multiple warp threads 30 and weft threads 35, and multiple fastener elements 51 woven into and fixed to a portion of the fastener tape 21b.
  • the warp threads 30 forming the fastener tape 21b have a plurality of first warp threads 31 having the same thickness and one second warp thread 32 thicker than the first warp thread 31, and the one second warp thread 32 is arranged on the side edge portion adjacent to the tape fold portion 23 of the tape body portion 22 of the fastener tape 21b.
  • the woven fastener stringer 20b of this embodiment 3 is formed by changing the second warp thread 32 arranged in the element attachment portion 24 of the fastener tape 21 in the hidden slide fastener 10 of the above-mentioned embodiment 1 to the first warp thread 31, but other than the change to the first warp thread 31, it is formed substantially the same as the woven fastener stringer 20 of the above-mentioned embodiment 1.
  • the fastener seat cover 3 of this embodiment 3 which is manufactured using such a hidden slide fastener 10b, when the left and right element rows 50 are engaged, the left and right skin members 8 of the seat cover 3 are butted against each other, so that the left and right element rows 50 are concealed by the seat cover 3.
  • each of the left and right sewing portions 60 is disposed below the second warp thread 32 disposed in the tape main body portion 22 (in other words, at a position closer to the element attachment portion 24 of the fastener tape 21b than the second warp thread 32).
  • the second warp threads 32 are arranged only on the tape body portion 22 of the fastener tape 21b. Therefore, when sewing the woven fastener stringer 20b to the seat cover 3 using a sewing machine, the element attachment portion 24 and element row 50 of the fastener tape 21b can be easily introduced into the element guide groove provided in the sewing machine foot. This makes it easier to perform the sewing process smoothly compared to, for example, the cases of the above-mentioned embodiments 1 and 2.
