Description
本発明は、靴の中底の下に敷く、すなわち靴の表底と中底の間に挿入する中物及びその製造方法に関し、クッション性及び通気性に優れると共に歪の少ない中物及びその製造方法に関するものである。 TECHNICAL FIELD The present invention relates to a midsole that is laid under the insole of a shoe , that is, inserted between the outsole and the midsole of the shoe, and a method for producing the same. It is about the method .
靴の製法の一つとして、靴の表底と中底の間に中物を挿入する方法が知られている。中物は、歩行時において緩衝材として作用するため、足に負荷される衝撃を和らげるという効果を奏するものである。 As one of shoe manufacturing methods, there is known a method of inserting an inside material between the outsole and the insole of the shoe. Since the medium-sized material acts as a cushioning material during walking, it has an effect of softening the impact applied to the foot.
従来より、中物としては、粉砕したコルクを薄い板状に成形したコルク材が用いられている。コルク材は軽くてクッション性に優れているため、良好な緩衝作用を奏し、好ましい素材である。しかしながら、通気性に劣るという欠点や、長期間使用すると歪が生じるという欠点があった。 Conventionally, a cork material obtained by molding crushed cork into a thin plate has been used as the medium. Since the cork material is light and has excellent cushioning properties, it exhibits a good cushioning effect and is a preferable material. However, it has a defect that it is inferior in breathability and that it is distorted after long-term use.
上記欠点を解決するためには、本発明者等は、表地と裏地とを連結糸で繋いでなる立体編物（ダブルラッセル編機によって編成された編物）を靴の中物に用いるのが適していると考え、種々の組織により立体編物を検討した。しかしながら、立体編物の組織によっては、表地と裏地とがずれやすく、形態安定性に劣ることがあった。また、形態安定性を向上させるために、表地、裏地及び連結糸の繊維密度を高めると、通気性が低下するということがあった。 In order to solve the above-mentioned drawbacks, the present inventors are suitable to use a three-dimensional knitted fabric (knitted by a double Russell knitting machine) in which the outer material and the lining are connected by a connecting yarn as the inner material of the shoe. Therefore, we investigated three-dimensional knitting by various organizations. However, depending on the structure of the three-dimensional knit, the outer material and the inner material are likely to be misaligned with each other, resulting in poor shape stability. Further, if the fiber density of the surface material, the lining material and the connecting yarn is increased in order to improve the morphological stability, the air permeability may decrease.
そこで、本発明は、形態安定性、クッション性及び通気性に優れると共に歪の少ない立体編物で構成された中物を提供することを課題とするものである。 Therefore, it is an object of the present invention to provide a middle material composed of a three-dimensional knitted fabric which is excellent in shape stability, cushioning property, and breathability and has less distortion.
本発明は、立体編物の編組織を以下のように工夫することにより、上記課題を解決したものである。すなわち、本発明は、靴の表底と中底の間に挿入する靴の中物であって、前記中物は立体編物で構成されてなり、前記立体編物は、表地、裏地及び前記表地と前記裏地とを繋ぐ連結糸とよりなり、前記表地の編組織は、４コースを最小単位として、２イン２アウトの状態で供給される第一の表地用糸と、２イン２アウトの状態で供給される第二の表地用糸とで構成され、該第一の表地用糸が左に２針分振られ、さらに左に２針分振られた２コースにおいて、該第二の表地用糸は右に２針分振られ、さらに右に２針分振られ、該第一の表地用糸が右に２針分振られ、さらに右に２針分振られた２コースにおいては、該第二の表地用糸は左に２針分振られ、さらに左に２針分振られた編組織となっており、前記裏地の編組織は、４コースを最小単位として、２イン２アウトの状態で供給される第一の裏地用糸と２イン２アウトの状態で供給される第二の裏地用糸とで構成され、該第一の裏地用糸が左に２針分振られ、さらに左に２針分振られた２コースにおいて、該第二の裏地用糸は右に２針分振られ、さらに右に２針分振られ、該第一の裏地用糸が右に２針分振られ、さらに右に２針分振られた２コースにおいては、該第二の裏地用糸は左に２針分振られ、さらに左に２針分振られた編組織となっており、前記表地及び前記裏地の編組織は、２ウェールのみずらされることにより、前記連結糸がウェール方向に斜交していることを特徴とする靴の中物及びその製造方法に関するものである。 The present invention has solved the above problems by devising the knitting structure of a three-dimensional knitted fabric as follows. That is, the present invention is a shoe inner product to be inserted between the outsole and the insole of the shoe, wherein the insole is composed of a three-dimensional knitted fabric, and the three-dimensional knitted fabric includes an outer material, a lining material, and the outer material. The knitting structure of the outer material, which is composed of a connecting yarn that connects the lining material, has four courses as a minimum unit and is supplied in a two-in-two-out state with a first outer-surface yarn and a two-in-two-out state. A second outer surface yarn to be supplied, wherein the first outer material yarn is shaken by 2 stitches to the left, and further 2 needles are swung to the left, in the second course, the second outer fabric thread Is swung by 2 stitches to the right, further swung by 2 stitches to the right, the first dressing yarn is swung by 2 stitches to the right, and further swung by 2 stitches to the right. The second outer fabric yarn has a knitting structure in which it is shaken by 2 stitches to the left and is further swung by 2 stitches to the left, and the knitting texture of the lining is a 2-in-2-out state with 4 courses as the minimum unit. And a second lining yarn supplied in a 2 in 2 out state, the first lining yarn is shaken by 2 stitches to the left, and further left In the two courses in which the second lining thread is shook by 2 stitches, the second lining thread is swung by 2 stitches to the right, and further by 2 stitches to the right, and the first lining thread is swung by 2 stitches to the right. In the two courses in which the second liner is further swung to the right by two stitches, the second liner yarn has a knitting structure that is swung to the left by two stitches and further swung to the left by two stitches. And, the knitting structure of the lining relates to the inside of a shoe and the manufacturing method thereof, wherein the connecting yarns are obliquely crossed in the wale direction by shifting only two wales.
本発明に係る靴の中物を構成している立体編物は、ダブルラッセル編機で編成されてなるものである。ダブルラッセル編機は、従来公知のものを用いればよいが、本発明においては、一対の表地用糸及び一対の裏地用糸を用い、しかも各々交互に左右に振って編み立てるため、筬の数を六枚にする必要がある。すなわち、前筬を二枚（Ｌ１、Ｌ２）、中筬を二枚（Ｌ３、Ｌ４）及び後筬を二枚（Ｌ５、Ｌ６）用いる。前筬Ｌ１には多数のガイド孔（ｎ１１，ｎ１２，ｎ１３，ｎ１４，ｎ１５，ｎ１６，・・・・）が設けられているが、このガイド孔ｎ１１及びｎ１２に第一の表地用糸を供給する。そして、ガイド孔ｎ１３及びｎ１４には第一の表地用糸が供給されずに、ガイド孔ｎ１５及びｎ１６において再び第一の表地用糸が供給され、このような供給態様が繰り返される。このような第一の表地用糸の供給方法は、２イン２アウトと呼ばれる。一方、前筬Ｌ２にも多数のガイド孔（ｎ２１，ｎ２２，ｎ２３，ｎ２４，ｎ２５，ｎ２６，ｎ２７，ｎ２６・・・・）が設けられており、このガイド孔ｎ２１及びｎ２２には第二の表地用糸は供給されずに、ガイド孔ｎ２３及びｎ２４に第二の表地用糸が供給される。そして、ガイド孔ｎ２５及びｎ２６には第二の表地用糸が供給されずに、ガイド孔ｎ２７及びｎ２８において再び第二の表地用糸が供給され、このような供給態様が繰り返される。このような第二の表地用糸の供給方法は、２イン２アウトと呼ばれる。そして、ガイド孔ｎ１１及びｎ１２に供給された第一の表地用糸と、ガイド孔ｎ２３及びｎ２４に供給された第二の表地用糸は、図２に示すように、前者が左に振って編み立てられていて、後者は右に振って編み立てられる。すなわち、第一の表地用糸及び第二の表地用糸は、各々交互に左右に振られて編み立てられるのである。また、裏地を編成する第一の裏地用糸及び第二の裏地用糸も後筬二枚（Ｌ５、Ｌ６）に、前記と同様にして２イン２アウトで供給され、図３に示すように、第一の裏地用糸及び第二の裏地用糸が各々交互に左右に振られて編み立てられる。そして、中筬Ｌ３には前筬Ｌ１及び後筬Ｌ５に対応して連結糸が供給され、中筬Ｌ４には、前筬Ｌ２及び後筬Ｌ６に対応して連結糸が供給される。 The three-dimensional knitted fabric that constitutes the inside of the shoe according to the present invention is knitted by a double Russell knitting machine. As the double Russell knitting machine, a conventionally known one may be used, but in the present invention, since a pair of surface material yarns and a pair of liner yarns are used, and each of them is knitted by alternately swinging left and right, the number of reeds Need to be six. That is, two front reeds (L1, L2), two middle reeds (L3, L4) and two rear reeds (L5, L6) are used. Before many guide holes in reed L1 is (n11, n12, n13, n14 , n15, n16, ····) but is provided, to supply the yarn for the first outer material to the guide hole n11 and n12 It Then, the first dress material yarn is not supplied to the guide holes n13 and n14, but the first dress material yarn is supplied again in the guide holes n15 and n16, and such a supply mode is repeated. Such a first method of supplying the outer material yarn is called 2-in/2-out. On the other hand, a number of guide holes before the reed L2 (n21, n22, n23, n24, n25, n26, n27, n26 ····) is provided, this guide hole n21 and n22 second Outer The second surface material thread is supplied to the guide holes n23 and n24 without supplying the material thread. Then, the second dress material yarn is not supplied to the guide holes n25 and n26, the second dress material yarn is supplied again in the guide holes n27 and n28, and such a supply mode is repeated. Such a second method for supplying the surface material yarn is called 2-in/2-out. Then, as shown in FIG. 2, the first dress material yarn supplied to the guide holes n11 and n12 and the second dress material yarn supplied to the guide holes n23 and n24 are knitted by waving the former to the left. It is erected and the latter is sewn to the right and knitted. That is, the first dress material yarn and the second dress material yarn are alternately swung right and left and knitted. Further, the first lining yarn and the second lining yarn for knitting the lining are also supplied to the two rear reeds (L5, L6) in the same manner as described above, 2 in 2 out, as shown in FIG. The first lining yarn and the second lining yarn are alternately swung right and left and knitted. Then, the connecting yarn is supplied to the middle reed L3 corresponding to the front reed L1 and the rear reed L5, and the middle reed L4 is supplied corresponding to the front reed L2 and the rear reed L6.
本発明に係る靴の中物を構成している立体編物の編組織は、４コースを最小単位として編成される。４コースを超える範囲を最小単位とすると、第一及び第二の表地用糸並びに第一及び第二の裏地用糸を各々交互に左右に振って編み立てることによって形成される目（編組織によって形成される小さな孔）が大きくなり、立体編物がずれやすくなったり、変形しやすくなって、形態安定性に劣る。また、４コース未満の範囲を最小単位とすると、目が小さくなりすぎて、通気性に劣る。上記したように、第一及び第二の表地用糸並びに第一及び第二の裏地用糸は、いずれも左右に振られて編み立てられるのであるが、その振り幅は２針である。振り幅が大きくなると、目が大きくなり、立体編物がずれやすくなる。 The knitting structure of the three-dimensional knitted fabric that constitutes the inside of the shoe according to the present invention is knitted with four courses as the minimum unit. When the range exceeding 4 courses is the minimum unit, the first and second outer fabric yarns and the first and second inner fabric yarns are alternately shaken from side to side and knitted to form stitches (depending on the knitting structure). The formed small holes) become large, and the three-dimensional knitted fabric is likely to be displaced or deformed, resulting in poor form stability. When the range of less than 4 courses is the minimum unit, the eyes become too small and the air permeability is poor. As described above, the first and second front surface yarns and the first and second backing yarns are both swayed right and left and knitted, and the swing width is 2 needles. When the swing width is large, the eyes are large and the three-dimensional knitted fabric is likely to shift.
また、この立体編物は、表地と裏地を編成する際に、両者は２ウェールのみずらして編み立てられる。これを図１に基づいて説明すると、以下のとおりである。図１の○は、第一の表地用糸及び第一の裏地用糸で編み立てられたループを示したものである。前筬Ｌ１のガイド孔ｎ１１及びｎ１２に供給された第一の表地用糸で編み立てられたループ○は、右側に２ウェールずれた後筬Ｌ５のガイド孔ｎ５１及びｎ５２に供給された第一の裏地用糸で編み立てられたループ○に対応するということである。したがって、第一の表地用糸で編み立てられたループ○に絡んだ連結糸は２ウェールずれて第一の裏地用糸で編み立てられたループ○に絡み、順次、これが繰り返されることになる。なお、第二の表地用糸及び第二の裏地用糸で編み立てられた各ループと連結糸との関係も同様である。したがって、連結糸は、ウェール方向に斜交することになる。表地と裏地の編成を２ウェールを超えてずらすと、連結糸が横臥する傾向となり、靴の中物としてのクッション性が低下するし、また歪やすくなる。表地と裏地の編成をずらさないか、又は１ウェールずらした場合、連結糸がほぼ垂直に立った状態となり、座屈が生じやすく、歪やすくなる。 Further, when knitting the front material and the lining material, the three-dimensional knitted fabric is knitted with a shift of two wales. This will be described below with reference to FIG. ○ in Figure 1, there is shown a first outer material yarn and a first knit erected loop yarns for lining. Before the reed L1 knitting erected loop ○ in first yarn for Outer supplied to the guide hole n11 and n12, first supplied to the guide hole n51 and n52 of the reed L5 after shifted 2 wales on the right It means that it corresponds to the loop ○ knitted with the lining thread. Therefore, the connecting yarn entangled in the loop ◯ knitted with the first outer material yarn is entangled in the loop ◯ knitted with the first lining yarn with a shift of 2 wales, and this is sequentially repeated. The relationship between each of the loops knitted with the second outer material yarn and the second inner material yarn and the connecting yarn is also the same. Therefore, the connecting yarns are obliquely crossed in the wale direction. If the knitting of the outer material and the lining material is shifted by more than 2 wales, the connecting yarn tends to lie down, and the cushioning property as the inner material of the shoe is deteriorated, and it is easily distorted. When the knitting of the front material and the lining material is not shifted, or when they are shifted by one wale, the connecting yarn is in a state of standing almost vertically, and buckling is likely to occur and distortion is likely to occur.
第一及び第二の表地用糸並びに第一及び第二の裏地用糸としては、マルチフィラメント糸が用いられ、特にポリエステルマルチフィラメント糸が用いられる。マルチフィラメント糸の繊度は、２００〜４００デシテックス／４０〜８０フィラメント程度のものが用いられる。第一及び第二の表地用糸並びに第一及び第二の裏地用糸は、一本のマルチフィラメント糸であってもよいし、二本以上の複数本のマルチフィラメント糸が引き揃えられたものであってもよい。また、二本以上の複数本のマルチフィラメント糸を撚って双糸等の糸条としてもよい。連結糸としては、剛性のあるモノフィラメント糸が用いられ、特にポリエステルモノフィラメント糸が用いられる。モノフィラメント糸の繊度は、１００〜３００デシテックスであるのが好ましい。また、モノフィラメント糸を二本以上引き揃えたものや、３〜５本からなるローカウント糸を連結糸として用いてもよい。 A multifilament yarn is used as the first and second outer fabric yarns and the first and second backing yarns, and in particular, a polyester multifilament yarn is used. The fineness of the multifilament yarn is about 200 to 400 decitex/40 to 80 filaments. The first and second surface yarns and the first and second lining yarns may be a single multifilament yarn, or two or more multifilament yarns are aligned. May be Also, two or more multifilament yarns may be twisted to form a yarn such as a twin yarn. As the connecting yarn, a rigid monofilament yarn is used, and particularly, a polyester monofilament yarn is used. The fineness of the monofilament yarn is preferably 100 to 300 decitex. Further, two or more monofilament yarns may be aligned and a low count yarn composed of 3 to 5 may be used as the connecting yarn.
タブルラッセル編機で編成された立体編物は、その後、熱処理を施してもよい。熱処理によって、立体編物が若干収縮し、形態安定性がより向上する。立体編物で構成される靴の中物の厚さは任意であるが、一般的に約３〜６ｍｍとなるように設定される。中物の形状も任意であるが、一般的に足裏の形状に合致するものとなっている。 The three-dimensional knitted fabric knitted by the table russell knitting machine may then be subjected to heat treatment. The heat treatment causes the three-dimensional knitted fabric to slightly shrink, and the morphological stability is further improved. The thickness of the inside of the shoe formed of the three-dimensional knit is arbitrary, but is generally set to be about 3 to 6 mm. The shape of the inside is also arbitrary, but it generally matches the shape of the sole.
本発明に係る靴の中物は、４コースを最小単位とする立体編物であるため、ずれや変形が少なく形態安定性に優れている。また、第一及び第二の表地用糸並びに第一及び第二の裏地用糸を用いて、図２及び図３に示す編成方法で、各々交互に左右に振られて編み立てることにより、編み立てられた表地及び裏地に、比較的小さな目が形成され、通気性が良好となる。また、表地及び裏地の編み立ては、２ウェールのみずらされ、連結糸がウェール方向に斜交していることにより、連結糸が垂直に立っている場合に比べて、荷重が負荷されても連結糸に座屈が生じにくく、歪を防止しうるという効果を奏する。 Since the inside of the shoe according to the present invention is a three-dimensional knitted fabric having four courses as the minimum unit, it is excellent in form stability with little deviation or deformation. Further, by using the first and second front surface yarns and the first and second backing yarns, the knitting method shown in FIG. 2 and FIG. Relatively small eyes are formed on the upholstered outer material and the lining material, and the breathability is improved. In addition, the knitting of the outer material and the lining is shifted by only two wales, and the connecting yarns are obliquely crossed in the wale direction, so that the connecting yarns are connected even when a load is applied, as compared with the case where the connecting yarns are standing vertically. The buckling of the yarn is unlikely to occur, and distortion can be prevented.
