Abstract
Description
本発明は、中間層に十字断面糸を使用することを特徴とするダブルラッセル地、及びこれを用いたシューズ用アッパー材に関する。 The present invention relates to a double raschel fabric characterized by using a cross-section yarn for an intermediate layer, and an upper material for shoes using the same.
ダブルラッセル地は表面、裏面、そして表面と裏面とをつなぐ中間層の３層構造を持ち、生地自体にクッション性があることで、それを活かしてベッドマット、椅子地、シューズ等に広く用いられている。例えば、特許文献１にはダブルラッセル地を用いたシューズが開示されている。 Double raschel has a three-layer structure consisting of a front surface, back surface, and an intermediate layer that connects the front and back surfaces, and the fabric itself has cushioning properties, so it is widely used for bed mats, chairs, shoes, etc. ing. For example, Patent Document 1 discloses a shoe using a double raschel ground.
しかしながら、クッション性を大きくしようとすれば、中間層に使用する糸の単糸繊度を大きく、また密度を大きくすればよいが、裏面から表面、表面から裏面への液体の移動が阻害されたり、コストが大きくなったり、重くなったりするという課題がある。一方で、裏面から表面、表面から裏面への液体の移動の向上を意図する場合、中間層に使用する糸の単糸繊度を小さく、また密度を大きくすればよいが、クッション性が損なわれたり、コストが大きくなったり、重くなったりするという課題がある。 However, if the cushioning properties are to be increased, the single yarn fineness of the yarn used for the intermediate layer may be increased, and the density may be increased, but the movement of the liquid from the back surface to the front surface and from the front surface to the back surface is inhibited, There is a problem that the cost increases or becomes heavy. On the other hand, when it is intended to improve the movement of liquid from the back surface to the front surface and from the front surface to the back surface, the single yarn fineness of the yarn used for the intermediate layer may be reduced and the density may be increased, but the cushioning property may be impaired. However, there is a problem that the cost increases or becomes heavy.
本発明の目的は、表面から裏面、裏面から表面への液体の大きな移動性を有しつつ、かつ、優れたクッション性を兼ね備える軽量なダブルラッセル地、及びこれを用いたシューズ用アッパー材を提供することである。 An object of the present invention is to provide a lightweight double raschel fabric having a large mobility of liquid from the front surface to the back surface and from the back surface to the front surface and also having an excellent cushioning property, and an upper material for shoes using the same. It is to be.
本発明の第一の構成は、表面、裏面、及びそれらをつなぐ中間層を有するダブルラッセル地において、該中間層の少なくとも一部に十字断面を有するモノフィラメントが用いられることを特徴とするダブルラッセル地である。 A first structure of the present invention is a double raschel ground having a front surface, a back surface, and an intermediate layer connecting them, and a monofilament having a cross-section is used for at least a part of the intermediate layer. It is.
本発明のダブルラッセル地は、前記十字断面を有するモノフィラメントがポリエステル繊維及び／またはポリアミド繊維からなることを特徴とすることが好ましい。 The double raschel fabric of the present invention is preferably characterized in that the monofilament having the cross section is made of a polyester fiber and / or a polyamide fiber.
また、本発明のダブルラッセル地は、前記十字断面を有するモノフィラメントが１０〜６０ｄＴｅｘの繊度であることを特徴とすることが好ましい。 In the double raschel fabric of the present invention, it is preferable that the monofilament having the cross section has a fineness of 10 to 60 dTex.

本発明の第二の構成は、前記ダブルラッセル地を用いたシューズ用アッパー材である。 The second configuration of the present invention is an upper material for shoes using the double raschel ground.
本発明により、表面から裏面、裏面から表面への液体の大きな移動性を有しつつ、かつ、クッション性も有する軽量なダブルラッセル地を提供し、その特長を活かし、特にシューズ用に使用することができる。なお、本発明における液体としては、シューズ用途の場合に足の部分に発生した汗等の水分を想定しており、本発明のダブルラッセル地は液体移動性が大きいために、乾きやすく、足の蒸れを軽減することができるといった効果を有する。 According to the present invention, a lightweight double raschel fabric having a large mobility of liquid from the front surface to the back surface and from the back surface to the surface and also having a cushioning property is utilized, and its features are utilized, particularly for shoes. Can do. As the liquid in the present invention, moisture such as sweat generated in the foot part in the case of shoes is assumed, and the double raschel land of the present invention has high liquid mobility, so it is easy to dry, It has the effect that dampness can be reduced.
以下に、本発明について詳細に説明する。
本発明においてダブルラッセル地とは、２列のニードルをもつダブルラッセル機で編み立てられた生地であり、表面、中間層、裏面の３層に区分されていることを特徴としている。８ゲージから２８ゲージまでのダブルラッセル機が一般的であり、本発明に使用される機械は特に限定されない。前記の２列のニードル間は通常「釜間」と呼ばれているが、この釜間についても制約は特になく、通常は１．５〜１０ｍｍが、生地厚、クッション性等から適宜選ばれる。特に、シューズ用アッパー材等に使用する場合、染色加工後の生地の厚みが１．３〜３ｍｍとなるように、釜間は１．５〜５ｍｍの間で選ばれることが好ましい。
The present invention is described in detail below.
In the present invention, the double raschel fabric is a fabric knitted by a double raschel machine having two rows of needles, and is characterized by being divided into three layers: a front surface, an intermediate layer, and a back surface. An 8-gauge to 28-gauge double raschel machine is common, and the machine used in the present invention is not particularly limited. The space between the two rows of needles is usually called “between the hooks”, but there is no particular restriction on the space between the hooks. Normally, 1.5 to 10 mm is appropriately selected from the fabric thickness, cushioning properties, and the like. In particular, when used as an upper material for shoes or the like, the space between the hooks is preferably selected between 1.5 and 5 mm so that the thickness of the dyed fabric becomes 1.3 to 3 mm.
本発明のダブルラッセル地において、表面、及び裏面に使用される糸の種類は特に限定されないが、シューズ用アッパー材等に使用される場合、機械的強度、耐薬品性、変色のしにくさ等からポリエステル繊維の使用が好ましい。また、表面、及び裏面に使用される糸の繊度についても特に限定されないが、５６〜７００ｄＴｅｘが一般的である。さらに、断面形状についても特に限定はなく、丸断面、異形断面いずれも用いることができる。 In the double raschel fabric of the present invention, the type of yarn used for the front and back surfaces is not particularly limited, but when used for shoe upper materials, etc., mechanical strength, chemical resistance, resistance to discoloration, etc. To polyester fibers are preferred. Moreover, although it does not specifically limit about the fineness of the thread | yarn used for the surface and a back surface, 56-700dTex is common. Further, the cross-sectional shape is not particularly limited, and either a round cross-section or an irregular cross-section can be used.
一方、本発明のダブルラッセル地の中間層に用いられる糸は、ポリエステル繊維及び／またはポリアミド繊維であることが好ましい。例えば、ポリプロピレン繊維では耐熱性が小さく好ましくないが、それらと比較して、耐熱性、機械的強度、耐薬品性に優れている点でポリエステル繊維、あるいはポリアミド繊維が好ましく、変色のしにくさから、ポリエステル繊維がより好ましい。すなわち、特に好ましいのは、表面、裏面、及び中間層に用いられるすべての糸がポリエステル繊維からなる態様である。 On the other hand, the yarn used for the intermediate layer of the double raschel fabric of the present invention is preferably a polyester fiber and / or a polyamide fiber. For example, polypropylene fibers have low heat resistance and are not preferable. However, polyester fibers or polyamide fibers are preferable because they are superior in heat resistance, mechanical strength, and chemical resistance. Polyester fibers are more preferable. That is, an embodiment in which all yarns used for the front surface, the back surface, and the intermediate layer are made of polyester fibers is particularly preferable.
本発明のダブルラッセル地は、中間層に用いられる糸の少なくとも一部が十字断面を有するモノフィラメントであることが必要である。本発明者らが鋭意検討を重ねた結果、丸断面に比べて軽量であること、中間層に用いたときにクッション性に優れること、さらに表面と裏面との間で液体の移動等が大きいことを見出し、断面形状が十字であるモノフィラメントを用いることが重要であることに到達した。 In the double raschel fabric of the present invention, it is necessary that at least a part of the yarn used for the intermediate layer is a monofilament having a cross section. As a result of intensive studies by the present inventors, it is lighter than a round cross section, has excellent cushioning properties when used in an intermediate layer, and has a large liquid movement between the front and back surfaces. And arrived at the importance of using monofilaments with a cross-sectional shape.
前記十字断面を有するモノフィラメントは、中間層全体に対して５０ｗｔ％以上用いられることが好ましい。５０ｗｔ％未満の場合には、クッション性、軽量性、液体の移動性が不十分となるおそれがあり好ましくない。 The monofilament having the cross section is preferably used in an amount of 50 wt% or more based on the entire intermediate layer. If it is less than 50 wt%, the cushioning property, lightness, and liquid mobility may be insufficient, which is not preferable.
また、前記十字断面を有するモノフィラメントの繊度は、１０〜６０ｄＴｅｘであることが好ましい。繊度が１０ｄＴｅｘより小さいとクッション性に劣り、６０ｄＴｅｘより大きいと重量が大きくなるため好ましくない。 Moreover, it is preferable that the fineness of the monofilament having the cross section is 10 to 60 dTex. When the fineness is smaller than 10 dTex, the cushioning property is inferior, and when it is larger than 60 dTex, the weight increases, which is not preferable.
前記十字断面を有するモノフィラメントの製造方法は特に限定されるものでなく、公知の方法を用いて丸断面のモノフィラメントと同様に生産できる。例えば、１ホールのノズルから溶融紡糸して巻き取る方法で作成しても構わないし、複数、具体的には１０のホール数を持つノズルから溶融紡糸して巻き取り、その後分繊工程で作成しても構わない。 The manufacturing method of the monofilament having the cross section is not particularly limited, and can be produced in the same manner as the monofilament having the round section using a known method. For example, it may be prepared by a method of melt spinning from a nozzle of 1 hole and winding it, or a plurality of, specifically, melt spinning and winding from a nozzle having a number of 10 holes, and then preparing by a fiber separation process. It doesn't matter.
本発明のダブルラッセル地は、上記機械、及び上記繊維を用いて生地を作成するが、その糸の組み合わせ、組織等に特に制約はない。例えば、シューズ用アッパー材用途では、表面にはハニカム構造が好適に使用され、裏面において、クサリ、テンビ、ハーフ、サテン、二目編等の組織、またはそれらを組み合わせた組織の無地構造が好適に使用される。また、該用途に用いる場合、厚みが１．３〜３ｍｍであることが好ましい。 The double raschel fabric of the present invention creates a fabric using the above machine and the above fibers, but there is no particular restriction on the combination of the yarn, the structure and the like. For example, in an upper material application for shoes, a honeycomb structure is preferably used on the front surface, and a plain structure of a structure such as a comb, tenbi, half, satin, or two stitches on the back surface, or a combination thereof is preferable. used. Moreover, when using for this use, it is preferable that thickness is 1.3-3 mm.
それらで得られた生地を染色加工して仕上げることが多く、それらの手法について特に制約はない。必要に応じ、染色工程を省いたり、抗菌、撥水等の付帯加工を施したりする場合もある。 In many cases, the dough obtained from them is dyed and finished, and there are no particular restrictions on these methods. If necessary, the dyeing process may be omitted, or additional processing such as antibacterial and water repellent may be performed.
本発明のダブルラッセル地は、表面と裏面との間の液体移動性とクッション性を兼ね備えた軽量の生地であることから、シューズ用アッパー材として好適に用いることができる。 The double raschel fabric of the present invention is a lightweight fabric having both liquid mobility and cushioning properties between the front surface and the back surface, and therefore can be suitably used as an upper material for shoes.
