　図１に示すようにスライドファスナー２００は、左右一対のファスナーストリンガー１００、及び左右一対のファスナーストリンガー１００を開閉するためのファスナースライダー３０を有する。各ファスナーストリンガー１００は、ファスナーテープ１０及びファスナーエレメント２０を含む。ファスナーテープ１０は、経糸（縦糸）と緯糸（横糸）が織られた織物であり、テープ主体部１２及びエレメント取り付け部１４を含む。後述の説明から明らかなように、経糸としては２種類の経糸が併用され、横糸としては１種類の横糸が用いられる。但し、別の形態においては、３種類以上の経糸が併用され、また２種類以上の緯糸が併用され得、このような形態も全て添付の請求の範囲内に含まれるものと解釈される。 1, the slide fastener 200 has a pair of left and right fastener stringers 100 and a fastener slider 30 for opening and closing the pair of left and right fastener stringers 100. Each fastener stringer 100 includes a fastener tape 10 and a fastener element 20. The fastener tape 10 is a woven fabric in which warp (warp) and weft (weft) are woven, and includes a tape main body 12 and an element mounting portion 14. As will be apparent from the description below, two types of warp are used together as the warp, and one type of weft is used as the weft. However, in another embodiment, three or more types of warp yarns may be used in combination, and two or more types of weft yarns may be used in combination, and all such configurations are interpreted as being included in the scope of the appended claims.
　テープ主体部１２は、エレメント取り付け部１４を除く領域であり、ミシン機などにより他の生地等に縫い付けられる領域である。エレメント取り付け部１４は、ファスナーエレメント２０が縫い付けられる部分を含み、またファスナーエレメント２０と重なり合う領域である。エレメント取り付け部１４は、ファスナーテープ１０において側縁部に位置し、対を為す他方のファスナーテープ１０の側縁部に対向した対向側縁部を包含する。図示のように、左側のファスナーテープ１０が右側のファスナーテープ１０を望む対向側縁部を有し、左側のファスナーエレメント２０が左側のファスナーテープ１０のその対向側縁部に縫い付けられる。また、右側のファスナーテープ１０が左側のファスナーテープ１０を望む対向側縁部を有し、右側のファスナーエレメント２０が右側のファスナーテープ１０のその対向側縁部に縫い付けられる。 The tape main part 12 is an area excluding the element attaching part 14 and is an area sewn to other fabrics by a sewing machine or the like. The element attaching portion 14 includes a portion to which the fastener element 20 is sewn, and is an area overlapping the fastener element 20. The element attachment portion 14 is located on the side edge portion of the fastener tape 10 and includes an opposite side edge portion that faces the side edge portion of the other fastener tape 10 that forms a pair. As shown in the figure, the left fastener tape 10 has an opposite side edge over which the right fastener tape 10 is desired, and the left fastener element 20 is sewn to the opposite edge of the left fastener tape 10. Also, the right fastener tape 10 has an opposite side edge over which the left fastener tape 10 is desired, and the right fastener element 20 is sewn to the opposite edge of the right fastener tape 10.
　ファスナーエレメント２０は、ファスナーテープ１０の長手方向に沿って連続して延びるようにファスナーテープ１０に対して縫い付けられる。ファスナーエレメント２０は、ファスナースライダー３０の前後移動によって対を為す他方のファスナーエレメント２０と噛み合い及び噛み合い解除される。必ずしもこの限りではないが、ファスナーエレメント２０は、本例においては、線状体であるフィラメントがコイル状に連続したコイルエレメントである。一例においては、コイルエレメントを構成するフィラメントは、単一材料から成るモノフィラメントである。一例においては、コイルエレメントを構成するフィラメントは、後述の芯紐、縫い糸、フィラメント糸と同じ素材から構成される。 The fastener element 20 is sewn to the fastener tape 10 so as to continuously extend along the longitudinal direction of the fastener tape 10. The fastener element 20 is engaged with and released from the other fastener element 20 that makes a pair by moving the fastener slider 30 back and forth. Although not necessarily limited to this, in this example, the fastener element 20 is a coil element in which filaments that are linear bodies are continuous in a coil shape. In one example, the filament constituting the coil element is a monofilament made of a single material. In one example, the filament constituting the coil element is made of the same material as a core string, sewing thread, and filament thread described later.
　ファスナーエレメント２０は、縫い糸２５によりファスナーテープ１０のエレメント取り付け部１４に対して縫い付けられる。エレメント取り付け部１４に対するファスナーエレメント２０の縫い付けは、工業用ミシンを用いて実行され、この際、経糸と緯糸が織られた組織のエレメント取り付け部１４に縫い糸２５が通されたミシン針が通される。ミシン針は鋭利な先端を有し、経糸同士の隙間、緯糸同士の隙間、経糸と緯糸の隙間を通過する。 The fastener element 20 is sewn to the element attachment portion 14 of the fastener tape 10 with a sewing thread 25. The sewing of the fastener element 20 to the element attaching portion 14 is performed using an industrial sewing machine. At this time, a sewing needle having a sewing thread 25 passed through the element attaching portion 14 of a structure in which warps and wefts are woven is passed. The The sewing needle has a sharp tip and passes through a gap between warps, a gap between wefts, and a gap between warps and wefts.
　ファスナーテープ１０は、図３に示すように、経糸６１と緯糸６２が織られた組織を有する。ファスナーテープ１０は、テープ主体部１２とエレメント取り付け部１４の間で同一の組織を有するが、両者の間において別の組織を有していても構わない。テープ主体部１２とエレメント取り付け部１４の境界以外の他の境界において異なる組織を有していても良い。 The fastener tape 10 has a structure in which warps 61 and wefts 62 are woven, as shown in FIG. The fastener tape 10 has the same structure between the tape main body 12 and the element mounting part 14, but may have another structure between the two. You may have a different structure | tissue in boundaries other than the boundary of the tape main-body part 12 and the element attachment part 14. FIG.
　図３は、２／２の組織を示すが、これは単なる一例であり、１／１の組織、３／３の組織、４／４の組織、若しくはこれ以外の組織も採用可能である。開示の一形態においては、ファスナーテープ１０の全体が２／２の組織であり、柔軟性が確保され、工業用ミシンのミシン針の良好な挿通が確保できる。なお、２／２の組織においては、一つの経糸６１に着目して見ると、４本の緯糸６２の下を延びた後、４本の緯糸６２の上を延びることを繰り返す。隣り合う４本の緯糸６２は、緯糸６２の折り返しに基づいて２本の緯糸と数えられる。一つの緯糸６２に着目して見ると、２本の緯糸６２の下を延びた後、２本の緯糸６２の上を延びることを繰り返す。緯糸６２には折り返しがないため、そのまま数えられる。ファスナーテープ１０の組織は、平織り、綾織り、及び朱子織り等の多様な織り方で構築することができる。 FIG. 3 shows a 2/2 organization, but this is merely an example, and a 1/1 organization, a 3/3 organization, a 4/4 organization, or any other organization may be employed. In one form of the disclosure, the entirety of the fastener tape 10 is a 2/2 structure, so that flexibility is ensured and good insertion of the sewing needle of the industrial sewing machine can be secured. In the structure of 2/2, when paying attention to one warp 61, it extends under the four wefts 62 and then extends over the four wefts 62. The four adjacent wefts 62 are counted as two wefts based on the folding back of the wefts 62. When paying attention to one weft thread 62, it extends repeatedly below the two weft threads 62 and then extends above the two weft threads 62. Since the weft 62 does not turn back, it is counted as it is. The structure of the fastener tape 10 can be constructed by various weaving methods such as plain weave, twill weave and satin weave.
　開示例のファスナーエレメント２０は、上述のようにコイルエレメントであり、図４及び図５に示すように、上脚２１、頭部２２、下脚２３、及び結合部２４から構成される単位が連続して成る。上脚２１は、ファスナーテープ１０の幅方向に沿って延び、本例においては、ファスナーテープ１０の幅方向に略平行である。上脚２１は、またファスナーテープ１０の緯糸６２に沿って延びる。上脚２１は、ファスナーテープ１０に対して接触せず、ファスナーテープ１０の上面から離間して設けられる。頭部２２は、上脚２１や下脚２３よりも線幅が太い部分である。隣り合う頭部２２の間に対を為す他方のファスナーエレメント２０の頭部２２が入り込むことにより、左右一対のファスナーエレメント２０同士の噛み合いが確保される。頭部２２は、上脚２１の内側端部と下脚２３の内側端部同士を連結するべく弧状に延びる。 The fastener element 20 of the disclosed example is a coil element as described above, and as shown in FIGS. 4 and 5, the unit composed of the upper leg 21, the head 22, the lower leg 23, and the coupling portion 24 is continuous. It consists of The upper leg 21 extends along the width direction of the fastener tape 10 and is substantially parallel to the width direction of the fastener tape 10 in this example. The upper leg 21 also extends along the weft thread 62 of the fastener tape 10. The upper leg 21 does not contact the fastener tape 10 and is provided apart from the upper surface of the fastener tape 10. The head 22 is a portion having a wider line width than the upper leg 21 and the lower leg 23. The engagement of the pair of left and right fastener elements 20 is ensured by the head 22 of the other fastener element 20 forming a pair entering between the adjacent heads 22. The head 22 extends in an arc shape so as to connect the inner ends of the upper legs 21 and the inner ends of the lower legs 23.
　下脚２３は、ファスナーテープ１０の幅方向に沿って延び、本例においては、ファスナーテープ１０の幅方向に略平行である。下脚２３は、またファスナーテープ１０の緯糸６２に沿って延びる。下脚２３は、ファスナーテープ１０の上面に接触する態様で延びる。結合部２４は、下脚２３の外側端部と一つ横の単位に属する上脚の外側端部の間を斜めに延びて連結する。 The lower leg 23 extends along the width direction of the fastener tape 10 and is substantially parallel to the width direction of the fastener tape 10 in this example. The lower leg 23 also extends along the weft thread 62 of the fastener tape 10. The lower leg 23 extends in a manner of contacting the upper surface of the fastener tape 10. The coupling portion 24 extends obliquely between the outer end portion of the lower leg 23 and the outer end portion of the upper leg belonging to one horizontal unit.
　ファスナーエレメント２０の各頭部２２は、略一定のピッチで設けられる。ファスナーエレメント２０の各構成単位の各上脚２１は、お互いに略平行に配向される。下脚２３についても同様であり、お互いに略平行に配向される。隣り合う単位間において上脚２１の間には間隔が設けられ、同様に下脚２３の間には間隔が設けられ、この間隔に対してミシン機のミシン針が挿通される。 Each head 22 of the fastener element 20 is provided at a substantially constant pitch. Each upper leg 21 of each structural unit of the fastener element 20 is oriented substantially parallel to each other. The same applies to the lower legs 23 and they are oriented substantially parallel to each other. Between adjacent units, an interval is provided between the upper legs 21, and similarly, an interval is provided between the lower legs 23, and a sewing machine needle of the sewing machine is inserted into this interval.
　必須の構成要素ではないが、ファスナーエレメント２０のコイルの中に芯紐２６を設けても良い。芯紐２６は、コイル状のファスナーエレメント２０を補強し、またファスナーテープ１０に対するファスナーエレメント２０の取り付け強度も高める。芯紐２６にもミシン機のミシン針が挿通される。一例においては、芯紐２６は、複数のフィラメント糸が撚られて形成された紐である。芯紐２６のフィラメント糸の素材は、例えば、後述のエレメント取り付け部１４の被縫付領域６５に含まれるフィラメント糸の素材と同一である。 Although not an essential component, the core string 26 may be provided in the coil of the fastener element 20. The core string 26 reinforces the coil-shaped fastener element 20 and also increases the attachment strength of the fastener element 20 to the fastener tape 10. The sewing machine needle of the sewing machine is also inserted into the core string 26. In one example, the core string 26 is a string formed by twisting a plurality of filament yarns. The material of the filament yarn of the core string 26 is the same as the material of the filament yarn included in the sewing region 65 of the element attachment portion 14 described later, for example.
　ファスナーエレメント２０及び芯紐２６は、１本以上の縫い糸を用いてファスナーテープ１０のエレメント取り付け部１４に対して縫い付けられる。図４及び図５においては、１本の縫い糸２５が用いられているが、別形態においては、２本以上の縫い糸が用いられる。一例においては、縫い糸２５は、フィラメント糸が撚り合わされて形成される。縫い糸２５のフィラメント糸の素材は、例えば、後述のエレメント取り付け部１４の被縫付領域６５に含まれるフィラメント糸の素材と同一である。 The fastener element 20 and the core string 26 are sewn to the element attachment portion 14 of the fastener tape 10 using one or more sewing threads. 4 and 5, one sewing thread 25 is used, but in another embodiment, two or more sewing threads are used. In one example, the sewing thread 25 is formed by twisting filament threads. The material of the filament yarn of the sewing thread 25 is the same as the material of the filament yarn included in the sewing region 65 of the element attachment portion 14 described later, for example.
　ファスナーエレメント２０をファスナーテープ１０に対して縫い付ける方法は任意であり、開示の例においては、２重環縫いが採用されているが、必ずしもこの限りではない。２重環縫いに際しては、ファスナーエレメント２０が置かれた側のファスナーテープ１０の面がルーパー側に配される。図４に示すように上脚２１が並走する３本の縫い糸２５により押さえつけられ、十分な位置安定性を確保することができる。 The method of sewing the fastener element 20 to the fastener tape 10 is arbitrary, and in the disclosed example, double ring stitching is adopted, but this is not necessarily the case. During double ring stitching, the surface of the fastener tape 10 on the side where the fastener element 20 is placed is arranged on the looper side. As shown in FIG. 4, the upper leg 21 is pressed by the three sewing threads 25 that run in parallel, and sufficient positional stability can be ensured.
　課題に関連して上述したように、スパン糸を含んで織成されたファスナーテープのファスナーストリンガーの中には耐久性試験をパスすることができないものが含まれ、その原因を究明して解決することが望まれていた。 As described above in connection with the problem, some fastener stringers of the fastener tape woven with span yarn cannot pass the durability test, and the cause is investigated and solved. It was hoped that.
　本実施形態においては、テープ主体部１２の経糸６１及び緯糸６２が、各々、スパン糸を含む。他方、経糸６１としてスパン糸に加えてフィラメント糸が併用され、エレメント取り付け部１４の経糸６１にはフィラメント糸が用いられる。 In the present embodiment, the warp yarn 61 and the weft yarn 62 of the tape main body 12 each include a span yarn. On the other hand, in addition to the spun yarn, a filament yarn is used in combination as the warp yarn 61, and the filament yarn is used as the warp yarn 61 of the element attachment portion 14.
　本願発明者の検討によれば、スパン糸はフィラメント糸よりも嵩高であり、これによりミシン針が貫通する際、ミシン針と一緒にファスナーテープを貫通する縫い糸がスパン糸に強く摩擦して縫い糸が傷つき、これが耐久性試験不合格の要因になっていることが予測される。テープ主体部１２とエレメント取り付け部１４を同一種類のスパン糸で織る通常の手法では、ミシン針が挿通される箇所で強度低下が生じてしまう。本実施形態においては、上述のように、エレメント取り付け部１４の経糸６１にはフィラメント糸が含められ、これによりファスナーストリンガーの耐久性が向上される。ファスナーストリンガーの耐久性は、例えば、閉じた状態のファスナーストリンガーをファスナーテープ幅方向に合致する方向に引っ張った時に受ける力に対する耐久性である。なお、一対のファスナーストリンガーが閉じた状態においては、各ファスナーエレメントが噛み合った状態にある。 According to the study of the present inventor, the spun yarn is bulkier than the filament yarn, so that when the sewing needle penetrates, the sewing yarn that penetrates the fastener tape together with the sewing needle strongly rubs against the span yarn and the sewing yarn becomes It is predicted that this is a cause of failure in the durability test. In a normal method of weaving the tape main body 12 and the element mounting portion 14 with the same type of spun yarn, the strength is reduced at the place where the sewing needle is inserted. In the present embodiment, as described above, the filament yarn is included in the warp yarn 61 of the element mounting portion 14, thereby improving the durability of the fastener stringer. The durability of the fastener stringer is, for example, durability against a force received when the closed fastener stringer is pulled in a direction matching the fastener tape width direction. When the pair of fastener stringers are closed, the fastener elements are engaged with each other.
　スパン糸との摩擦による縫い糸の強度低下は、大型のファスナーエレメントを大型のファスナーテープに縫い付ける場合にはさほど顕在化しない可能性がある。すなわち、小型のファスナーエレメントを小型のファスナーテープに対して縫い付ける場合には、ファスナーテープに対して高密度でミシン針が打ち込まれることになる。この場合、縫い糸が受けるダメージも大きくなり、これがファスナーストリンガーの耐久性試験不合格につながる。他方、大型のファスナーエレメントを大型のファスナーテープに対して縫い付ける場合には、ミシン針の打ち込み密度が小さく、縫い糸が受けるダメージも小さくなる。 The decrease in the strength of the sewing thread due to friction with the span thread may not be so obvious when sewing a large fastener element on a large fastener tape. That is, when sewing a small fastener element to a small fastener tape, the sewing needles are driven at a high density with respect to the fastener tape. In this case, the damage received by the sewing thread also increases, which leads to failure of the fastener stringer durability test. On the other hand, when a large fastener element is sewn to a large fastener tape, the driving density of the sewing needle is small and damage to the sewing thread is small.
　もちろん、本願に開示の発明が小型のファスナーエレメントを用いる場合に限られるべきではないが、大型のファスナーエレメントよりも小型のファスナーエレメントを用いる場合において顕著な効果を得ることができる。顕著な効果が得られる一例においては、ファスナーテープの長手方向の１０ｃｍの単位長に６０個以上のファスナーエレメント頭部が設けられる。別例においては、ファスナーテープの１０ｃｍの単位長に６５個以上のファスナーエレメント頭部が設けられる。更なる別例においては、ファスナーテープの１０ｃｍの単位長に７０個以上、又は８０個以上、又は９０個以上のファスナーエレメント頭部が設けられる。単位長当たりの頭部の個数の上限に限度はないが、例えば、９０個、１００個、１１０個、１２０個、１３０個、１４０個、１５０個、１６０個、１７０個、１８０個、１９０個、又は２００個である。特に好適には、ファスナーテープの１０ｃｍの単位長に７５個～８５個のファスナーエレメント頭部が設けられる。 Of course, the invention disclosed in the present application should not be limited to the case where a small fastener element is used, but a remarkable effect can be obtained when a small fastener element is used rather than a large fastener element. In an example in which a remarkable effect is obtained, 60 or more fastener element heads are provided in a unit length of 10 cm in the longitudinal direction of the fastener tape. In another example, 65 or more fastener element heads are provided in a unit length of 10 cm of the fastener tape. In still another example, 70 or more, or 80 or more, or 90 or more fastener element heads are provided in a unit length of 10 cm of the fastener tape. There is no upper limit on the number of heads per unit length, but for example, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190 Or 200. Particularly preferably, 75 to 85 fastener element heads are provided in a unit length of 10 cm of the fastener tape.
　１０ｃｍの単位長に６０個のファスナーエレメント頭部が設けられた場合のミシン針の打ち込み数は６０回である。好適な７５個～８５個のファスナーエレメント頭部が設けられた場合のミシン針の打ち込み回数は７５～８５回である。比較例として、大型のファスナーエレメントは、１０ｃｍの単位長に５５個以下のファスナーエレメント頭部が設けられる。一例においては、大型のファスナーエレメントのミシン針の打ち込み回数は、小型のファスナーエレメントのミシン針の打ち込み数に対して約１０％以上少ない打ち込み数である。 The number of driving of the sewing needle is 60 times when 60 fastener element heads are provided in a unit length of 10 cm. When the preferred 75 to 85 fastener element heads are provided, the number of times the sewing needle is driven is 75 to 85 times. As a comparative example, a large fastener element is provided with 55 or less fastener element heads in a unit length of 10 cm. In one example, the number of times the sewing needle of the large fastener element is driven is about 10% or more less than the number of times the sewing needle of the small fastener element is driven.
　スパン糸について本段落にて定義を述べる。スパン糸は、１種以上の短繊維が紡績により形成された糸である。スパン糸においては、「撚り」により短繊維の抜け落ちが抑止されており、また短繊維により羽毛が付与される。本願においては、スパン糸は、短繊維のみから構成されたものに限定されず、短繊維に加えて長繊維が含められたものも含意し、つまり、スパン糸は、少なくとも短繊維を含む糸である。換言すれば、スパン糸は、長繊維に対して短繊維が複合された複合糸も含意する。例えば、スパン糸は、長繊維（コア）の周りを短繊維で被覆したようなコア・スパン糸も含意する。非限定の一例としては、スパン糸は、ポリエステルの長繊維とレーヨンの短繊維が撚り合わされた糸である。 The definition of span yarn is described in this paragraph. A spun yarn is a yarn in which one or more short fibers are formed by spinning. In the spun yarn, the falling of the short fibers is suppressed by “twisting”, and feathers are imparted by the short fibers. In the present application, the spun yarn is not limited to those composed only of short fibers, but also includes those in which long fibers are included in addition to short fibers, that is, the spun yarn is a yarn including at least short fibers. is there. In other words, the spun yarn also implies a composite yarn in which short fibers are combined with long fibers. For example, the spun yarn also implies a core / spun yarn in which a long fiber (core) is covered with a short fiber. As a non-limiting example, the spun yarn is a yarn obtained by twisting polyester long fibers and rayon short fibers.
　フィラメント糸について本段落にて定義を述べる。フィラメント糸は、１種以上の長繊維が束ねられて撚り合わされた糸である。フィラメント糸においては、「撚り」により長繊維同士が絡み合い、糸としての特性（非限定の例としては、糸の強さ、糸の太さ、糸の丸み、糸の弾力や伸力、糸の光沢等）が現れる。非限定の一例としては、フィラメント糸は、ポリエステルの長繊維が撚られた糸である。 The definition of filament yarn is described in this paragraph. A filament yarn is a yarn in which one or more types of long fibers are bundled and twisted together. In filament yarn, long fibers are entangled by “twisting” and the properties of the yarn (non-limiting examples include yarn strength, yarn thickness, yarn roundness, yarn elasticity and elongation, (Gloss etc.) appears. As a non-limiting example, the filament yarn is a yarn in which long polyester fibers are twisted.
　一般的には、スパン糸は、糸の表面に羽毛が存在し、柔らかく、膨らみがある。フィラメント糸は、糸の表面に羽毛がなく、滑らかで光沢がある。 Generally speaking, the spun yarn is soft and swollen with feathers on the surface of the yarn. Filament yarns are smooth and glossy with no feathers on the yarn surface.
　スパン糸は、紡績糸とも呼ばれる。従って、紡績糸との比較においてフィラメント糸を非紡績糸と呼んでも構わない。スパン糸が羽毛を有する見地からスパン糸を羽毛含有糸と呼び、フィラメント糸を羽毛非含有糸と呼んでも良い。スパン糸が起毛されているとの見地から、スパン糸を起毛糸と呼び、フィラメント糸を非起毛糸と呼んでも良い。請求項に対してこの名称の読み替えを適用しても良い。 Spun yarn is also called spun yarn. Therefore, in comparison with the spun yarn, the filament yarn may be called a non-spun yarn. From the standpoint that the spun yarn has feathers, the spun yarn may be called a feather-containing yarn, and the filament yarn may be called a feather-free yarn. From the viewpoint that the spun yarn is raised, the spun yarn may be called a raised yarn, and the filament yarn may be called a non-raised yarn. This replacement of the name may be applied to the claims.
　非限定の例示の形態においては、スパン糸は、２種類以上の繊維を含む混紡糸である。非限定の例示の形態においては、フィラメント糸は、一種類の長繊維から成り、別の実施形態においては２種以上の長繊維から成る。スパン糸に含まれる短繊維の例としては、各種の天然繊維（木綿、麻、リンネル、竹、羊毛、カシミヤ、アルパカ、モヘア、アンゴラ、及び絹等）が例示でき、また再生繊維（ビスコースレーヨン、アセテート、キュプラ、リヨセル、ポリエステル繊維等）も例示できる。スパン糸のコア及びフィラメント糸の長繊維は、再生繊維、合成繊維（ナイロン、ポリエステル、アクリル、ビニロン、ポリオレフィン（ポリエチレン、ポリプロピレン等）、ポリウレタン等）が例示でき、一例としては、ナイロン繊維又はポリエステル繊維である。非限定の例示の形態においては、長繊維が化学繊維であり、紡糸工程を経て製造される。 In a non-limiting exemplary form, the spun yarn is a blended yarn comprising two or more types of fibers. In a non-limiting exemplary form, the filament yarn consists of one type of long fiber, and in another embodiment, consists of two or more types of long fiber. Examples of short fibers contained in spun yarns include various natural fibers (cotton, hemp, linen, bamboo, wool, cashmere, alpaca, mohair, angora, silk, etc.) and regenerated fibers (viscose rayon) And acetate, cupra, lyocell, polyester fiber, etc.). Examples of the long fiber of the spun yarn and filament yarn include recycled fiber and synthetic fiber (nylon, polyester, acrylic, vinylon, polyolefin (polyethylene, polypropylene, etc.), polyurethane, etc.), for example, nylon fiber or polyester fiber It is. In a non-limiting exemplary form, the long fibers are chemical fibers and are manufactured through a spinning process.
　なお、ポリエステルとは、ポリエチレンテレフタレート、ポリトリメチレンテレフタレート、ポリブチレンテレフタレート、ポリナフタレート、ポリブチレンナフタレート等を包含する用語である。非限定の例示の形態においては、ポリエステルは、ポリエチレンテレフタレートである。 Polyester is a term including polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polynaphthalate, polybutylene naphthalate, and the like. In a non-limiting exemplary form, the polyester is polyethylene terephthalate.
　スパン糸若しくはフィラメント糸に付与される撚りの程度は、任意であり、甘撚、強撚、普通撚りのいずれであっても構わない。撚りの方向も任意であり、「Ｓ撚り」や「Ｚ撚り」のいずれであっても構わない。 The degree of twist imparted to the spun yarn or filament yarn is arbitrary, and may be any of sweet twist, strong twist, and ordinary twist. The direction of twisting is also arbitrary, and may be either “S twist” or “Z twist”.
　図６を参照してエレメント取り付け部１４に織り込まれるフィラメント糸の経糸の範囲について説明する。ミシン針が挿通する範囲に対応してフィラメント糸の経糸を織り込むことが好適である。非限定の例示の形態においては、フィラメント糸の数が増えると、スパン糸を用いたファスナーテープ１０の風合いが変化してしまうため、フィラメント糸の多用は避けることが望ましい。 The range of the warp of the filament yarn woven into the element mounting portion 14 will be described with reference to FIG. It is preferable to weave the warp of the filament yarn corresponding to the range through which the sewing needle is inserted. In the non-limiting exemplary embodiment, when the number of filament yarns increases, the texture of the fastener tape 10 using the spun yarn changes, so it is desirable to avoid excessive use of filament yarns.
　第１例においては、フィラメント糸の経糸が、図６の経糸６１ｄ～６１ｇの合計４本に用いられる。緯糸６２は、全てスパン糸である。スパン糸の緯糸６２にフィラメント糸の経糸６１ｄ～６１ｇが織られた被縫付領域６５ｐが設けられる。被縫付領域６５は、ファスナーテープ１０の長い方向に長い長尺な領域である。被縫付領域６５の長さは、ファスナーテープ１０の長さに等しい。被縫付領域６５の幅は、本例では、そこに含まれるフィラメント糸の経糸６１の幅の合計に略等しい。 In the first example, the warp of the filament yarn is used for a total of four warps 61d to 61g in FIG. The weft yarns 62 are all spun yarns. A spanned weft 62 is provided with a sewing region 65p in which filament warp yarns 61d to 61g are woven. The sewing region 65 is a long region that is long in the long direction of the fastener tape 10. The length of the sewing area 65 is equal to the length of the fastener tape 10. In this example, the width of the sewing region 65 is substantially equal to the total width of the warp yarns 61 of the filament yarns included therein.
　被縫付領域６５は、縫い糸２５が縫い付けられる際にミシン針が貫通する領域でもある。ミシン針は、縫う際に幅方向に若干横揺れする場合がある。従って、ミシン針の横揺れに対処してミシン針の確実な貫通を確保するために被縫付領域６５が設けられる。縫い糸の種類、縫い方、縫う位置の変更もあり得る。これらの変更に対処するために、線ではなく領域として把握される被縫付領域６５が設けられる。なお、被縫付領域６５は、ミシン針が貫通するための領域として設定されるため、縫い糸２５の幅方向両側の経糸２本以上を含む。 The sewing area 65 is also an area through which the sewing needle penetrates when the sewing thread 25 is sewn. The sewing needle may roll slightly in the width direction when sewing. Accordingly, the sewing region 65 is provided to cope with the roll of the sewing needle and to ensure the reliable penetration of the sewing needle. The type of sewing thread, the sewing method, and the sewing position can be changed. In order to cope with these changes, a sewing area 65 that is grasped as an area rather than a line is provided. In addition, since the to-be-sewn area 65 is set as an area through which the sewing needle penetrates, it includes two or more warps on both sides in the width direction of the sewing thread 25.
　必ずしもこの限りではないが、本例では、被縫付領域６５ｐがエレメント取り付け部１４に含まれる。エレメント取り付け部１４に対してファスナーエレメント２０を縫い付ける際、ミシン針が被縫付領域６５ｐに差し込まれる。ミシン針は、フィラメント糸の経糸６１同士の間に差し込まれる。ミシン針は、スパン糸の緯糸６２同士の間に差し込まれる。被縫付領域６５ｐの経糸６１ｄ～６１ｇがフィラメント糸であり、縫い糸が受けるダメージが低減できる。被縫付領域６５ｐの幅をＷ６５ｐとする。 Although not necessarily limited to this, in this example, the sewing region 65p is included in the element attachment portion 14. When the fastener element 20 is sewn to the element attachment portion 14, the sewing needle is inserted into the sewing area 65p. The sewing needle is inserted between the warp yarns 61 of the filament yarn. The sewing needle is inserted between the weft yarns 62 of the span yarn. The warp yarns 61d to 61g in the sewing area 65p are filament yarns, and the damage received by the sewing yarn can be reduced. The width of the sewing area 65p is W65p.
　第２例においては、フィラメント糸の経糸が、図６の経糸６１ｃ～６１ｈの合計６本に用いられる。緯糸６２は、全てスパン糸である。スパン糸の緯糸６２にフィラメント糸の経糸６１ｃ～６１ｈが織られた被縫付領域６５ｑが設けられる。本例においても被縫付領域６５ｑがエレメント取り付け部１４に含まれる。被縫付領域６５ｑは、その幅をＷ６５ｑとし、第１例の被縫付領域６５ｐの幅Ｗ６５ｐよりも幅広である。従って、ミシン針との関係における被縫付領域６５の位置精度が緩和される。好適には、被縫付領域６５には６本以上の経糸６１が含められる。エレメント取り付け部１４に対してファスナーエレメント２０を縫い付ける際、ミシン針が被縫付領域６５ｑに差し込まれる。ミシン針は、フィラメント糸の経糸６１同士の間に差し込まれる。ミシン針は、スパン糸の緯糸６２同士の間に差し込まれる。被縫付領域６５ｑの経糸６１ｃ～６１ｈがフィラメント糸であり、縫い糸が受けるダメージが低減できる。 In the second example, the warp of the filament yarn is used for a total of six warps 61c to 61h in FIG. The weft yarns 62 are all spun yarns. A spanned weft 62 is provided with a sewing region 65q in which filament warp yarns 61c to 61h are woven. Also in this example, the sewing region 65q is included in the element attachment portion 14. The to-be-sewn area 65q has a width of W65q and is wider than the width W65p of the to-be-sewn area 65p of the first example. Therefore, the positional accuracy of the sewing area 65 in relation to the sewing needle is relaxed. Preferably, the sewing area 65 includes six or more warps 61. When the fastener element 20 is sewn to the element attachment portion 14, the sewing needle is inserted into the sewing area 65q. The sewing needle is inserted between the warp yarns 61 of the filament yarn. The sewing needle is inserted between the weft yarns 62 of the span yarn. The warp yarns 61c to 61h in the to-be-sewn area 65q are filament yarns, and the damage received by the sewing yarn can be reduced.
　第３例においては、フィラメント糸の経糸が、図６の経糸６１ａ～６１ｊの合計１０本に用いられる。緯糸６２は、全てスパン糸である。スパン糸の緯糸６２にフィラメント糸の経糸６１ａ～６１ｊが織られた被縫付領域６５ｒが設けられる。本例においても被縫付領域６５ｒがエレメント取り付け部１４に含まれ、端的には、被縫付領域６５ｒがエレメント取り付け部１４に合致する。被縫付領域６５ｒは、その幅をＷ６５ｒとし、第１及び第２例の被縫付領域６５ｐ、６５ｑの幅Ｗ６５ｐ、Ｗ６５ｑよりも幅広である。従って、ミシン針との関係における被縫付領域６５の位置精度が緩和される。エレメント取り付け部１４に対してファスナーエレメント２０を縫い付ける際、ミシン針が被縫付領域６５ｒに差し込まれる。ミシン針は、フィラメント糸の経糸６１同士の間に差し込まれる。ミシン針は、スパン糸の緯糸６２同士の間に差し込まれる。被縫付領域６５ｒの経糸６１ａ～６１ｊがフィラメント糸であり、縫い糸が受けるダメージが低減できる。 In the third example, the warp of the filament yarn is used for a total of ten warp yarns 61a to 61j in FIG. The weft yarns 62 are all spun yarns. A spanned weft 62 is provided with a sewing area 65r in which filament warp yarns 61a to 61j are woven. Also in this example, the sewn area 65r is included in the element attaching part 14, and the sewn area 65r coincides with the element attaching part 14 at the end. The to-be-sewn area 65r has a width of W65r and is wider than the widths W65p and W65q of the to- be-sewn areas 65p and 65q of the first and second examples. Therefore, the positional accuracy of the sewing area 65 in relation to the sewing needle is relaxed. When the fastener element 20 is sewn to the element attachment portion 14, the sewing needle is inserted into the sewing area 65r. The sewing needle is inserted between the warp yarns 61 of the filament yarn. The sewing needle is inserted between the weft yarns 62 of the span yarn. The warp yarns 61a to 61j in the to-be-sewn area 65r are filament yarns, and the damage received by the sewing yarn can be reduced.
　第１乃至第３例においてはフィラメント糸の経糸６１の数が最大１０本であるが、１０本以上でもよく、例えば、１２本、１４本、１６本である。第１乃至第３例において明示はしていないが、ファスナーテープ１０を構成する経糸６１の数は、５０本～７０本である。非限定の例示の形態においては、エレメント取り付け部１４に含まれる被縫付領域６５を構成するフィラメント糸の経糸６１の本数は、ファスナーテープ１０全体の総経糸数の１０％以上２４％以下である。換言すると、フィラメント糸の経糸６１の本数は、５本以上１３本以下である。スパン糸の経糸に対するフィラメント糸の経糸の織り込み割合が、１０％以上２４％以下であるとも説明できる。この場合、被縫付領域６５からのミシン針の打ち込み外れを抑止しつつ、スパン糸に依存する良好な風合いのテープ主体部１２が維持できる。 In the first to third examples, the number of the warp 61 of the filament yarn is 10 at the maximum, but may be 10 or more, for example, 12, 14, or 16. Although not explicitly shown in the first to third examples, the number of warps 61 constituting the fastener tape 10 is 50 to 70. In a non-limiting exemplary form, the number of filament yarn warps 61 constituting the sewing region 65 included in the element attachment portion 14 is 10% or more and 24% or less of the total number of warps of the entire fastener tape 10. . In other words, the number of warp yarns 61 of the filament yarn is 5 or more and 13 or less. It can also be explained that the weaving ratio of the warp of the filament yarn to the warp of the spun yarn is 10% or more and 24% or less. In this case, it is possible to maintain the tape main body portion 12 having a good texture depending on the spun yarn while preventing the sewing needle from coming off from the sewing region 65.
　第１乃至第３例においては、エレメント取り付け部１４に被縫付領域６５の全体が含められ、またファスナーエレメント２０と重なり合うように被縫付領域６５が設けられる。この場合、ファスナーストリンガー１００の上面を見た時の被縫付領域６５の露出が回避される。ファスナースライダー３０の引手を図１とは反対側に設ける場合、被縫付領域６５が積極的に露出することになるが、この場合においては、被縫付領域６５をデザイン上のアクセントとして利用する余地がある。フィラメント糸は、スパン糸とは異なる染色性を有する場合がある。例えば、フィラメント糸は、ある特定の染料に対してスパン糸よりも濃く若しくは薄く染色される。フィラメント糸を含む被縫付領域６５が、テープ主体部１２や被縫付領域６５を除くエレメント取り付け部１４よりも濃く又は薄く染まり、デザイン上の効果を付加的に同時に得ることができる。 In the first to third examples, the entire sewing area 65 is included in the element attaching portion 14, and the sewing area 65 is provided so as to overlap the fastener element 20. In this case, exposure of the sewing region 65 when the upper surface of the fastener stringer 100 is viewed is avoided. When the handle of the fastener slider 30 is provided on the side opposite to that in FIG. 1, the sewing area 65 is positively exposed. In this case, the sewing area 65 is used as an accent on the design. There is room. Filament yarns may have different dyeability than spun yarns. For example, filament yarns are dyed darker or lighter than spun yarns for certain dyes. The sewn area 65 including the filament yarn is dyed darker or lighter than the element attaching part 14 excluding the tape main body 12 and the sewn area 65, and the design effect can be additionally obtained simultaneously.
　第１乃至第３例においては、被縫付領域６５の経糸６１には複数のフィラメント糸が含められるが、被縫付領域６５以外にはフィラメント糸が含められない。フィラメント糸は、スパン糸よりも伸縮性が劣る場合があり、また短繊維の不存在から質感も異なる。従って、フィラメント糸の経糸が織り込まれる領域を被縫付領域６５に限定することにより、スパン糸主体のファスナーテープの特性・質感を確保することができる。 In the first to third examples, the warp yarn 61 in the sewing area 65 includes a plurality of filament yarns, but no filament thread is included in areas other than the sewing area 65. The filament yarn may be less stretchable than the spun yarn, and the texture is different due to the absence of short fibers. Therefore, by limiting the region in which the warp of the filament yarn is woven into the sewing region 65, it is possible to ensure the characteristics and texture of the fastener tape mainly composed of the spun yarn.
　第２及び第３例においては、被縫付領域６５の幅が、上脚２１若しくは下脚２３の長さの１／２以上である。図６に示すように、上脚２１が長さＬ２１を有する。上脚２１は、結合部２４の上端部と頭部２２の上端部を接続するべく延びる。例えば、上脚２１の長さＬ２１の一端が、コイルエレメントのフィラメントの線幅が変化する点である。例えば、上脚２１の長さＬ２１の他端が、結合部２４のＵ字状の底位置である。第３例においては、被縫付領域６５の幅が、上脚２１若しくは下脚２３の長さの３／４以上である。 In the second and third examples, the width of the sewing region 65 is ½ or more of the length of the upper leg 21 or the lower leg 23. As shown in FIG. 6, the upper leg 21 has a length L21. The upper leg 21 extends to connect the upper end portion of the coupling portion 24 and the upper end portion of the head portion 22. For example, one end of the length L21 of the upper leg 21 is a point at which the line width of the coil element filament changes. For example, the other end of the length L 21 of the upper leg 21 is the U-shaped bottom position of the coupling portion 24. In the third example, the width of the sewing area 65 is 3/4 or more of the length of the upper leg 21 or the lower leg 23.
　第２及び第３例においては、被縫付領域６５の幅が、芯紐２６の幅Ｗ２６以上である。第１乃至第３例においては、被縫付領域６５の幅が、ファスナーエレメント２０の最大幅Ｗ２０以下である。必ずしもこの限りではないが、上述した条件のいずれか一つを満足することが望ましい。 In the second and third examples, the width of the sewing region 65 is equal to or greater than the width W26 of the core string 26. In the first to third examples, the width of the sewing region 65 is equal to or less than the maximum width W20 of the fastener element 20. Although not necessarily limited to this, it is desirable to satisfy any one of the above-described conditions.
　図７乃至図９を参照してファスナーテープ１０に対してファスナーエレメント２０をミシン機により縫い付ける工程を説明する。この工程の前、ファスナーテープ１０は、自動織機等の織機により経糸と緯糸から織成される。本例においては、ファスナーテープ１０に用いられる経糸は、スパン糸が主であるが、上述のようにエレメント取り付け部１４にはフィラメント糸が含められ、これにより被縫付領域６５が画定される。ファスナーテープ１０に用いられる緯糸は、スパン糸のみである。なお、適切に構成された織機が、経糸としてスパン糸とフィラメント糸を併用し、ファスナーテープを織成できることは当業者には技術常識である。 A process of sewing the fastener element 20 to the fastener tape 10 with a sewing machine will be described with reference to FIGS. Prior to this step, the fastener tape 10 is woven from warps and wefts by a loom such as an automatic loom. In this example, the warp yarn used for the fastener tape 10 is mainly a spun yarn. However, as described above, the element attachment portion 14 includes a filament yarn, thereby defining a sewing region 65. The weft used for the fastener tape 10 is only a spun yarn. In addition, it is common technical knowledge to those skilled in the art that a suitably configured loom can weave a fastener tape by using a spun yarn and a filament yarn as warps.
　図７に示すようにミシン機３００は、ベース３２０に凹み３２５が設けられ、これに対して噛合状態の左右のファスナーエレメント２０が供給される。ベース３２０上には左右のファスナーテープ１０が供給され、各ファスナーテープ１０の内側の側縁部が各ファスナーエレメント２０上に置かれる。ファスナーテープ１０上には押さえ部材３１０が配され、ベース３２０上においてファスナーエレメント２０とファスナーテープ１０を押さえつける。この状態において、ミシン針３０５とルーパー３３０の作動が開始する。２重環縫いの具体的なメカニズムは本技術分野においては周知であり、詳細な説明は省略する。ミシン針３０５の昇降に際しては、図８に模式的に示すように、ミシン針３０５がファスナーテープ１０のエレメント取り付け部１４と芯紐２６に差し込まれる。ミシン針３０５は、被縫付領域６５に差し込まれ、この被縫付領域６５にはフィラメント糸の経糸６１が含められている。ミシン針３０５から受けるダメージが低減される。ミシン機による縫い付け後、図９に示すようにファスナーエレメント２０がファスナーテープ１０に対してしっかりと縫い付けられる。 As shown in FIG. 7, in the sewing machine 300, a recess 320 is provided in the base 320, and the right and left fastener elements 20 in an engaged state are supplied thereto. The left and right fastener tapes 10 are supplied onto the base 320, and the side edges inside the fastener tapes 10 are placed on the fastener elements 20. A pressing member 310 is disposed on the fastener tape 10 and presses the fastener element 20 and the fastener tape 10 on the base 320. In this state, the operation of the sewing needle 305 and the looper 330 starts. The specific mechanism of the double chain stitch is well known in this technical field, and detailed description thereof is omitted. When the sewing needle 305 is raised and lowered, the sewing needle 305 is inserted into the element attaching portion 14 and the core cord 26 of the fastener tape 10 as schematically shown in FIG. The sewing needle 305 is inserted into the sewing area 65, and the warp area 61 of the filament yarn is included in the sewing area 65. Damage received from the sewing needle 305 is reduced. After sewing by the sewing machine, the fastener element 20 is firmly sewn to the fastener tape 10 as shown in FIG.
　ファスナーテープ１０に対するファスナーエレメント２０の縫い付け後、樹脂製の止具、本例においては樹脂製の開離嵌挿具５０が金型成形により一体的に設けられる。開離嵌挿具５０の蝶棒５１が、芯紐２６や被縫付領域６５を被覆する。また、開離嵌挿具５０の箱棒５２及び箱部５３が、芯紐２６や被縫付領域６５を被覆する。これにより、芯紐２６や被縫付領域６５の露出を阻止することができる。なお、開離嵌挿具は、止具の一例であり、別の構成の止具の採用も可能である。 After the fastener element 20 is sewn to the fastener tape 10, a resin stopper, in this example, a resin separation / insertion tool 50, is integrally provided by molding. The butterfly stick 51 of the opening / closing insertion tool 50 covers the core string 26 and the sewing region 65. Further, the box bar 52 and the box portion 53 of the separation / insertion tool 50 cover the core string 26 and the sewing region 65. Thereby, exposure of the core string 26 and the to-be-sewn area 65 can be prevented. The opening / closing insertion tool is an example of a stopper, and a stopper having a different configuration may be employed.
　ファスナースライダー３０でのファスナーストリンガー１００の開閉に際しては、ファスナースライダー３０の本体がファスナーテープ１０に接触して擦れる場合がある。図１０及び１１に示すように、ファスナースライダー３０の摺動時、ファスナースライダー３０の上翼板３１、下翼板３２、フランジ部３１ａ、３２ａがファスナーテープ１０に接触してファスナーテープ１０が擦れる可能性がある。 When the fastener stringer 100 is opened and closed by the fastener slider 30, the body of the fastener slider 30 may come into contact with and rub against the fastener tape 10. As shown in FIGS. 10 and 11, when the fastener slider 30 is slid, the upper wing plate 31, the lower wing plate 32, and the flange portions 31 a and 32 a of the fastener slider 30 may come into contact with the fastener tape 10 and rub the fastener tape 10. There is sex.
　本実施形態においては、エレメント取り付け部１４にはフィラメント糸の経糸が含まれており、これにより、擦れに対する耐性が強化される。またフィラメント糸は、スパン糸のような羽毛がないため、ファスナースライダー３０と擦れることも抑止され、ファスナースライダー３０のより容易な摺動が促進される。なお、図１０は、被縫付領域６５がエレメント取り付け部１４よりも幅広であることを例示する。 In the present embodiment, the element attaching portion 14 includes a warp of a filament yarn, thereby enhancing resistance to rubbing. Further, since the filament yarn does not have a feather like a spun yarn, it is also prevented from rubbing against the fastener slider 30 and easier sliding of the fastener slider 30 is promoted. In addition, FIG. 10 illustrates that the to-be-sewn area 65 is wider than the element attachment portion 14.
＜第２実施形態＞
　図１２を参照して第２実施形態について説明する。第１実施形態の開示においては、被縫付領域６５においてフィラメント糸の経糸がファスナーテープ１０の幅方向に連続して設けられ、また被縫付領域６５を構成する経糸は全てフィラメント糸であった。本実施形態においては、被縫付領域６５がフィラメント糸の経糸とスパン糸の経糸が交互に織り込まれる。このような場合においても被縫付領域６５に存在するフィラメント糸のおかげで被縫付領域６５のミシン針に対する改善された耐性が確保できる。 Second Embodiment
A second embodiment will be described with reference to FIG. In the disclosure of the first embodiment, the warp yarn of the filament yarn is continuously provided in the width direction of the fastener tape 10 in the sewing region 65, and the warp yarns constituting the sewing region 65 are all filament yarns. . In the present embodiment, the warped yarn 65 and the warp yarn of the span yarn are woven in the sewing region 65 alternately. Even in such a case, improved resistance to the sewing needles in the sewing region 65 can be ensured by virtue of the filament yarn present in the sewing region 65.
　図１２に示すように、被縫付領域６５ｒに含まれる経糸６１のうち、経糸６１ａ、６１ｃ、６１ｅ、６１ｇ、６１ｉがスパン糸であり、経糸６１Ｂ、６１Ｄ、６１Ｆ、６１Ｈ、６１Ｊがフィラメント糸である。被縫付領域６５に含まれるフィラメント糸の経糸の数は、被縫付領域６５に含まれるスパン糸の数以上であることが望ましく、例えば、２／３以上である。 As shown in FIG. 12, of the warp yarns 61 included in the sewing region 65r, the warp yarns 61a, 61c, 61e, 61g, 61i are span yarns, and the warp yarns 61B, 61D, 61F, 61H, 61J are filament yarns. is there. The number of warp yarns of the filament yarn included in the sewing region 65 is desirably equal to or more than the number of span yarns included in the sewing region 65, and is, for example, 2/3 or more.
＜第３実施形態＞
　図１３を参照して第３実施形態について説明する。第１実施形態の図１０に関連して述べたように、必ずしも被縫付領域６５の全体がエレメント取り付け部１４に包含される必要はない。図１３に示すように、被縫付領域６５がエレメント取り付け部１４よりも幅広であり、テープ主体部１２側へ拡張されても構わない。この場合、被縫付領域６５が部分的にエレメント取り付け部１４に含まれるが、被縫付領域６５が全体的にエレメント取り付け部１４に含まれない。このような場合においても上述の実施形態で説明したものと同様の効果を得ることができる。 <Third Embodiment>
A third embodiment will be described with reference to FIG. As described with reference to FIG. 10 of the first embodiment, the entire sewing region 65 does not necessarily need to be included in the element attachment portion 14. As shown in FIG. 13, the to-be-sewn area 65 is wider than the element attaching part 14, and may be extended to the tape main-body part 12 side. In this case, the sewing region 65 is partially included in the element attachment portion 14, but the sewing region 65 is not entirely included in the element attachment portion 14. Even in such a case, the same effects as those described in the above embodiment can be obtained.
＜実施例＞
　ファスナーテープのテープ主体部が、スパン糸の経糸と緯糸で構成され、エレメント取り付け部がフィラメント糸の経糸とスパン糸の緯糸で構成されたファスナーテープを織機により製造した。織機の動作モードを適切に設定し、スパン糸とフィラメント糸を供給源に投入し、織機を稼働させた。得られたファスナーテープでは、エレメント取り付け部の経糸が全てフィラメント糸であり、当然に被縫付領域も全てフィラメント糸である。その後、１０ｃｍの単位長に８０個程度の頭部が含まれるコイル状のファスナーエレメントをファスナーテープのエレメント取り付け部に対して２重環縫いにより縫い付けた。その後、ファスナーストリンガーを染色し、乾燥等の後処理を施した。 <Example>
A fastener tape in which the tape main portion of the fastener tape was composed of warp yarns and wefts of span yarn, and the element attachment portion was composed of warp yarns of filament yarn and weft yarns of span yarn was manufactured by a loom. The loom operating mode was set appropriately, spun yarn and filament yarn were charged into the supply source, and the loom was operated. In the obtained fastener tape, the warp yarns of the element attachment portion are all filament yarns, and naturally the sewing region is also the filament yarn. Thereafter, a coil-shaped fastener element including about 80 heads in a unit length of 10 cm was sewn to the element attachment portion of the fastener tape by double ring stitching. Thereafter, fastener stringers were dyed and subjected to post-treatment such as drying.
　材料については次の材料を用いた。ファスナーテープの経糸及び緯糸に用いられるスパン糸は、ポリエステルの長繊維とレーヨンの短繊維が撚り合わされて成る。ファスナーテープの経糸に用いられるフィラメント糸は、ポリエステルの長繊維のみが撚り合わされて成る。芯紐は、ポリエステルの長繊維が撚り合わされて成る。縫い糸は、ポリエステルの長繊維のみが撚り合わされて成る。 The following materials were used for the materials. The spun yarn used for the warp and weft of the fastener tape is formed by twisting polyester long fibers and rayon short fibers. The filament yarn used for the warp of the fastener tape is formed by twisting only polyester long fibers. The core string is formed by twisting long polyester fibers. The sewing thread is formed by twisting only polyester long fibers.
　なお、上記の実施例において、テープ主体部を構成する経糸には、その総本数に対して、８/１０以上、好ましくは９/１０以上の本数のスパン糸が含まれる。この場合、残りの経糸には、２/１０以下もしくは１/１０以下のフィラメント糸が含まれる。別例においては、テープ主体部の全ての経糸がスパン糸である。 In the above embodiment, the warp yarns constituting the tape main part include 8/10 or more, preferably 9/10 or more, of span yarns with respect to the total number of the yarns. In this case, the remaining warp includes a filament yarn of 2/10 or less or 1/10 or less. In another example, all the warp yarns of the tape main body are spun yarns.
　エレメント取り付け部を構成する経糸には、その総本数に対して、６/１０以上、好ましくは８／１０以上の本数のフィラメント糸が含まれる。この場合、残りの経糸には、４／１０以下、若しくは２／１０以下のスパン糸が含まれる。別例においては、エレメント取り付け部の全ての経糸がフィラメント糸である。 The warp yarns constituting the element attaching portion include 6/10 or more, preferably 8/10 or more filament yarns with respect to the total number. In this case, the remaining warp includes 4/10 or less, or 2/10 or less of spun yarn. In another example, all the warp yarns of the element attachment portion are filament yarns.
　テープ主体部におけるスパン糸が占める割合は、その他の種類の経糸が占める割合よりも大きい。エレメント取り付け部におけるフィラメント糸が占める割合は、その他の種類の経糸が占める割合よりも大きい。 The proportion of span yarn in the tape main part is greater than the proportion of other types of warp. The proportion of filament yarns in the element attachment portion is greater than the proportion of other types of warp yarns.
　一対のファスナーストリンガーを噛み合わせた状態で噛み合わせを解除する力を付与する試験において不良品の発生の低下が確認できた。エレメント取り付け部のミシン針に対する耐性が高められたことが貢献したものと考えられる。 In the test of applying a force for releasing the engagement with the pair of fastener stringers engaged, it was confirmed that the generation of defective products was reduced. The increased resistance of the element mounting part to the sewing needle is thought to have contributed.
　上述の教示を踏まえると、当業者をすれば、各実施形態に対して様々な変更を加えることができる。請求の範囲に盛り込まれた符号は、参考のためであり、請求の範囲を限定解釈する目的で参照されるべきものではない。請求項においては、スパン糸の経糸を第１経糸と呼び、フィラメント糸の経糸を第２経糸と呼んで両者を区別しているが、これは便宜状の問題である。経糸として第３、第４、第５経糸などの他の経糸が織り込まれも良い。緯糸として、第２、第３、第４、第５緯糸等の他の緯糸が織り込まれても良い。 Based on the above teaching, those skilled in the art can make various modifications to the embodiments. Reference signs included in the claims are for reference only and should not be referenced for the purpose of limiting the scope of the claims. In the claims, the warp of the spun yarn is called the first warp and the warp of the filament yarn is called the second warp to distinguish them, but this is a matter of convenience. Other warps such as third, fourth, and fifth warps may be woven as warps. As the weft, other wefts such as second, third, fourth, and fifth wefts may be woven.
