しかしながら、これらの技術は、立体編物の表面風合の改良には有効であるものの、立体編物に色柄や、凹凸感等の意匠性や機能性を付与するようなものではなかった。   However, although these techniques are effective in improving the surface texture of a three-dimensional knitted fabric, they have not been designed to impart design or functionality such as a color pattern or unevenness to the three-dimensional knitted fabric.

本発明は、かかる技術的背景に鑑みてなされたもので、優れた通気性とクッション性能を有する立体編物に意匠性を付与し、自動車、列車等の座席シートや、椅子等に用いられる座席シート用表皮材を提供し、さらに優れた通気性を利用して効果的に各種機能性を付与するものである。   The present invention has been made in view of such a technical background, and imparts designability to a three-dimensional knitted fabric having excellent breathability and cushioning performance, and is used for seat seats for automobiles, trains, etc., seats, etc. An outer skin material is provided, and various functionalities are effectively imparted by utilizing excellent air permeability.

本発明者らは、このような課題を解決するために鋭意検討の結果、優れた通気性とクッション性能を有する立体編物に、接着層を介して織物または編物から選ばれる布帛を表皮層として積層し、通気性のある接着層や立体編物に各種機能性を付与することにより、意匠性があり通気性とクッション性能を有し各種機能性のある座席シート用布帛の得られることを見出し本発明に到達した。本発明は、以下の手段を提供する。   As a result of intensive studies to solve such problems, the present inventors laminated a fabric selected from a woven fabric or a knitted fabric as a skin layer through an adhesive layer on a three-dimensional knitted fabric having excellent breathability and cushioning performance. In addition, it has been found that by providing various functionalities to an air-permeable adhesive layer and a three-dimensional knitted fabric, it is possible to obtain fabrics for seat sheets having design properties, air permeability and cushion performance, and various functionalities. Reached. The present invention provides the following means.

[1]基材層と表皮層と接着層からなる座席シート用布帛において、前記基材層が、互いに離間して配置された一対の編地と、該編地間を往復して両者を結合する連結糸とから編成された立体編物から構成され、前記表皮層が、織物または編物から選ばれる布帛からなることを特徴とする座席シート用布帛。 [1] In a seat sheet fabric comprising a base material layer, a skin layer, and an adhesive layer, the base material layer is reciprocally connected between the pair of knitted fabrics arranged apart from each other and the knitted fabrics. A seat seat fabric, comprising a three-dimensional knitted fabric knitted from connecting yarns, wherein the skin layer is made of a fabric selected from a woven fabric or a knitted fabric.

[2]前記接着層が、不織布からなり接着剤を含浸し通気性を有することを特徴とする前項1に記載の座席シート用布帛。 [2] The seat sheet fabric according to item 1, wherein the adhesive layer is made of a nonwoven fabric, impregnated with an adhesive, and has air permeability.

[3]前記接着層及び/又は前記基材層に消臭剤を担持させたことを特徴とする前項1または2に記載の座席シート用布帛。 [3] The seat seat fabric according to item 1 or 2, wherein a deodorant is supported on the adhesive layer and / or the base material layer.

[4]前記表皮層が立毛布帛からなることを特徴とする前項1〜3のいずれか1項に記載の座席シート用布帛。 [4] The seat sheet fabric according to any one of items 1 to 3, wherein the skin layer is a standing fabric.

[1]の発明では、基材層と表皮層と接着層からなる座席シート用布帛において、前記基材層が、互いに離間して配置された一対の編地と、該編地間を往復して両者を結合する連結糸とから編成された立体編物から構成されているので、クッション性と通気性の優れた基材層とすることができる。さらに、前記表皮層が、織物または編物から選ばれる布帛であって基材層に接着層を介して一体化されるので、基材層の単調な編み目が最表面に現れることなく、織物や編物の布帛の様々な特性が基材層である立体編物に付与することができる。   In the invention of [1], in the fabric for seat sheets composed of a base material layer, a skin layer, and an adhesive layer, the base material layer reciprocates between the pair of knitted fabrics arranged apart from each other and the knitted fabric. Therefore, the base material layer is excellent in cushioning properties and air permeability. Furthermore, since the skin layer is a fabric selected from a woven fabric or a knitted fabric and is integrated with the base material layer via an adhesive layer, a monotonous stitch of the base material layer does not appear on the outermost surface, and the woven fabric or the knitted material. Various properties of the fabric can be imparted to the three-dimensional knitted fabric that is the base material layer.

[2]の発明では、前記接着層が、不織布からなり接着剤を含浸し通気性を有するものであるので、不織布の繊維のアンカー効果により接着強度を保ったまま接着剤を少なくすることができ、通気性も確保することができる。そのため、立体編物の優れたクッション性と通気性に影響を少なくして基材層と表皮層を一体化することができる。   In the invention of [2], since the adhesive layer is made of a nonwoven fabric and impregnated with an adhesive and has air permeability, the adhesive can be reduced while maintaining the adhesive strength by the anchor effect of the fibers of the nonwoven fabric. Also, air permeability can be ensured. Therefore, the base material layer and the skin layer can be integrated with less influence on the excellent cushioning property and air permeability of the three-dimensional knitted fabric.

[4]の発明では、前記表皮層が立毛布帛からなるので、立毛布帛の様々な風合(例えば、柄や凹凸感等の意匠性やタッチ感)を、基材層である立体編物に付与することができる。   In the invention of [4], since the skin layer is made of a raised fabric, various textures of the raised fabric (for example, design properties such as patterns and unevenness and touch feeling) are imparted to the three-dimensional knitted fabric that is the base material layer. can do.

また、本発明を、そのまま従来のウレタン等のクッション材と表皮材に代えて座席シートに使用すれば、座席シートの軽量化と省スペース化を図ることができる。   Further, if the present invention is used as it is for a seat seat in place of a conventional cushion material such as urethane and a skin material, the seat seat can be reduced in weight and space.

本発明の座席シート用布帛について、図を参照しながら説明する。図1に示すように、本発明の座席シート用布帛1は、基材層2と表皮層3と接着層4とからり、基材層2と表皮層3が接着層4を介して一体化していることを特徴とする。   The seat seat fabric of the present invention will be described with reference to the drawings. As shown in FIG. 1, the seat seat fabric 1 of the present invention includes a base material layer 2, a skin layer 3, and an adhesive layer 4, and the base material layer 2 and the skin layer 3 are integrated via the adhesive layer 4. It is characterized by.

基材層2は、立体編み物で、互いに離間して配置された一対の編地(5、6)と、該編地間を往復して両者を結合する連結糸7とから編成されている。立体編み物は、二列の針列を有するダブルラッセル機、ダブル丸編機等で編成する編物であって、互いに離間して配置された上下一対の編地を編むベース糸と両者を結合する連結糸で編成される。   The base material layer 2 is a three-dimensional knitted fabric, and is knitted from a pair of knitted fabrics (5, 6) that are spaced apart from each other and a connecting yarn 7 that reciprocates between the knitted fabrics to join them together. A three-dimensional knitted fabric is a knitted fabric knitted by a double raschel machine having two rows of needles, a double circular knitting machine, etc., and a base yarn for knitting a pair of upper and lower knitted fabrics spaced apart from each other, and a coupling that couples them together Knitted with yarn.

上下一対の編地の組織は、特に限定されないが、表皮層3との接着性と積層後に編地組織の影響が表皮層3に現れないようにするためにも、上側の編地5の組織は、ウェール方向及びコース方向のいずれの方向にも連続したフラットな編地構造とし、下側の編地6の組織は、メッシュ組織やマーギゼット組織等の開口部を有する編地にして通気性を向上した組織にするのが好ましい。もちろん、上下一対の編地組織は、同じ組織であってもよく、異なる組織であってもよく任意である。   The structure of the pair of upper and lower knitted fabrics is not particularly limited, but the structure of the upper knitted fabric 5 is also used in order to prevent the influence of the knitted fabric structure from appearing on the skin layer 3 after adhesion and lamination with the skin layer 3. Is a flat knitted fabric structure that is continuous in both the wale direction and the course direction, and the lower knitted fabric 6 is made of a knitted fabric having openings such as a mesh structure or a marguette structure to provide air permeability. It is preferable to have an improved organization. Of course, the pair of upper and lower knitted fabric structures may be the same structure or different structures, and are arbitrary.

連結糸7は、上下一対の編地が所定の間隔を保持するように、一対の編地間に編み込んだもので、立体編物に所定のクッション性を付与する。連結糸7は、繰り返し着座すると反発感が徐々に低下することを防ぐため、トラスト組織のように連結するのが好ましい。   The connecting yarn 7 is knitted between a pair of knitted fabrics so that the pair of upper and lower knitted fabrics maintain a predetermined interval, and imparts a predetermined cushioning property to the three-dimensional knitted fabric. The connecting thread 7 is preferably connected like a trust structure in order to prevent the rebound feeling from gradually lowering when seated repeatedly.

また、立体編物を編成する糸の素材としては、特に限定しないが、ポリエチレンテレフタレート、ポリブチレンテレフタレートに代表されるポリエステル樹脂、ナイロン6等のポリアミド樹脂、ポリエチレン、ポリプロピレン等のポリオレフィン樹脂等の合成繊維のマルチフィラメントやモノフィラメントが好適に用いられ、繊維断面としては、丸断面であっても、扁平もしくは異形断面であってもよい。中でもポリエステル樹脂は、リサイクル性に優れており、さらに、上下一対の編地を形成するベース糸としては、柔らかいものがよく、200〜2500dtexのポリエステルマルチフィラメント糸が好適で、連結糸としては、クッション性を保つためにも150〜1500dtexのポリエステルモノフィラメント糸が好適である。   In addition, the material of the yarn for knitting the three-dimensional knitted fabric is not particularly limited, but it is not limited to polyethylene terephthalate, polyester resin typified by polybutylene terephthalate, polyamide resin such as nylon 6, and synthetic fiber such as polyolefin resin such as polyethylene and polypropylene. Multifilaments and monofilaments are preferably used, and the fiber cross section may be a round cross section or a flat or irregular cross section. Among them, the polyester resin is excellent in recyclability. Further, as the base yarn for forming the pair of upper and lower knitted fabrics, a soft yarn is preferable, and a polyester multifilament yarn of 200 to 2500 dtex is preferable. In order to maintain the properties, a polyester monofilament yarn of 150 to 1500 dtex is preferable.

表皮層3は、織物または編物から選ばれる布帛であって、従来から座席シート用表皮材として使用されている布帛でよい。中でもポリエステル繊維製の布帛は、リサイクル性に優れており立体編物と合わせてポリエステル製にするのが好ましい。また、基材層の立体編み物をそのまま座席シート用表皮材として使用することもできるが、立体編み物をそのまま座席シート用表皮材として使用した場合には、タバコの火等によってあいた穴や刃物等によってできた傷が広がりやすく、本発明のように立体編み物を基材層とし、織物等の表皮層と張り合わすことによって立体編み物の欠点を補うことができる。   The skin layer 3 is a fabric selected from a woven fabric or a knitted fabric, and may be a fabric conventionally used as a skin material for seat sheets. Among these, a polyester fiber fabric is excellent in recyclability and is preferably made of polyester together with a three-dimensional knitted fabric. In addition, the three-dimensional knitting of the base material layer can be used as it is as the seat material for the seat, but when the three-dimensional knitting is used as it is as the seat material for the seat, it is possible to use a hole or a blade cut by a cigarette fire or the like. The resulting scratches are easy to spread, and the defects of the three-dimensional knitted fabric can be compensated by using the three-dimensional knitted fabric as a base material layer and pasting it with a skin layer such as a woven fabric as in the present invention.

接着層4の樹脂又はゴムラテックスを張り合わす方法は、ロールコーター法、スプレー法、プリント法等、公知の方法で樹脂又はゴムラテックスを表皮層裏面に塗布し基材層と張り合わして乾燥すればよく特に限定するものではない。また、接着層の接着剤としては、従来からよく使われる樹脂又はゴムラテックスでよく特に限定されないが、例えば樹脂としてはアクリル系、ウレタン系、ポリ塩化ビニル、ポリエチレン、ポリプロピレン、エチレン−酢酸ビニル共重合体(EVA)等の樹脂が挙げられる。ゴムラテックスのゴム成分としてはSBR(スチレン−ブタジエンゴム)、NBR(アクリロニトリル−ブタジエンゴム)、MBR(メチルメタクリレート−ブタジエンゴム)あるいは天然ゴム等が挙げられる。中でもホツレ強度をより向上させることのできるアクリル系樹脂が好ましい。   The method of laminating the resin or rubber latex of the adhesive layer 4 is to apply the resin or rubber latex to the back surface of the skin layer by a known method such as a roll coater method, a spray method, a printing method, etc. There is no particular limitation. In addition, the adhesive for the adhesive layer may be a resin or rubber latex that has been conventionally used, and is not particularly limited. Examples of the resin include acrylic, urethane, polyvinyl chloride, polyethylene, polypropylene, and ethylene-vinyl acetate copolymer. Resins such as coalescence (EVA) are exemplified. Examples of the rubber component of the rubber latex include SBR (styrene-butadiene rubber), NBR (acrylonitrile-butadiene rubber), MBR (methyl methacrylate-butadiene rubber), and natural rubber. Among them, an acrylic resin that can further improve the hot strength is preferable.

接着剤の塗布量としては、10〜150g/m(乾燥後重量)とするのが好ましい。10g/m未満では、裁断時にほつれ易く好ましくない。また、150g/mを超えても座席シート用表皮材の重量が増大し、風合も固くなるので好ましくない。また、接着剤には無機充填剤が添加されることもあるが、本発明においても無機充填剤を添加してもよい。無機充填剤としては特に限定しないが、炭酸カルシウム、水酸化アルミニウム、水酸化マグネシウム、シリカ等を例示できる。 The coating amount of the adhesive is preferably 10 to 150 g / m 2 (weight after drying). If it is less than 10 g / m < 2 >, it is easy to fray at the time of cutting and is not preferable. Moreover, even if it exceeds 150 g / m < 2 >, since the weight of the skin material for seat sheets increases and a feel becomes hard, it is not preferable. Moreover, although an inorganic filler may be added to an adhesive agent, you may add an inorganic filler also in this invention. Although it does not specifically limit as an inorganic filler, A calcium carbonate, aluminum hydroxide, magnesium hydroxide, a silica etc. can be illustrated.

また、基材層2と表皮層3が接着層4を介して一体化するときに、図3のように接着層4として樹脂又はゴムラテックス単体だけで張り合わせてもよいが、図4のように表皮層裏面に塗布した接着剤(樹脂又はゴムラテックス)に重ねて、不織布を挿入し、さらに基材層2と重ねてから、押圧して、不織布に前記接着剤を含浸させて、通気性のある接着層4として一体化してもよい。こうすることによって不織布の繊維のアンカー効果によって基材層2と表皮層3の接着強度を確保でき、接着剤を少なくすることもできて、通気性を確保しやすくすることができるので、基材層2である立体編物の優れたクッション性と通気性を確保したまま、基材層と表皮層を一体化することができる。このときの接着剤の塗布量としては、8〜80g/m(乾燥後重量)とすることができる。 In addition, when the base material layer 2 and the skin layer 3 are integrated via the adhesive layer 4, as shown in FIG. 3, the adhesive layer 4 may be bonded only with resin or rubber latex alone, but as shown in FIG. Overlay the adhesive (resin or rubber latex) applied to the back of the skin layer, insert the non-woven fabric, and further overlap with the base material layer 2, and press to impregnate the non-woven fabric with the adhesive. The adhesive layer 4 may be integrated. By doing so, the anchoring effect of the nonwoven fabric fibers can ensure the adhesive strength between the base material layer 2 and the skin layer 3, the adhesive can be reduced, and the air permeability can be easily ensured. The base material layer and the skin layer can be integrated while ensuring excellent cushioning properties and air permeability of the solid knitted fabric that is the layer 2. As an application quantity of the adhesive agent at this time, it can be set as 8-80 g / m < 2 > (weight after drying).

前記不織布としては、繊維のアンカー効果の発揮しやすいニードルパンチ不織布やウォーターパンチ不織布が好ましい。不織布を構成する繊維については特に限定されないが、リサイクル性の観点からはポリエステル繊維が好適である。   The nonwoven fabric is preferably a needle punch nonwoven fabric or a water punch nonwoven fabric that easily exhibits the fiber anchor effect. Although it does not specifically limit about the fiber which comprises a nonwoven fabric, From the viewpoint of recyclability, a polyester fiber is suitable.

また、本発明では、前記基材層2及び/又は接着層4に消臭剤を担持させるのが好ましい。接着剤(樹脂又はゴムラテックス)に消臭剤を混入して、表皮層裏面に塗布する方法が簡単で好ましいが、その効果をより発揮するために基材層2に、バインダー樹脂を介して消臭剤を担持させることもできる。また、表皮層3にも本発明の妨げにならない程度に、難燃性、消臭性、防汚性、防虫性、抗菌性等の機能性薬剤を担持させることもできる。また、不織布に接着剤を含浸させて通気性のある接着層4とする場合の不織布に予め消臭剤を担持したものを使用してもよい。   In the present invention, it is preferable that a deodorant is carried on the base material layer 2 and / or the adhesive layer 4. A method of mixing a deodorant in an adhesive (resin or rubber latex) and applying it to the back surface of the skin layer is simple and preferable. However, in order to exert its effect, the base layer 2 is erased via a binder resin. An odorant can also be carried. In addition, functional agents such as flame retardancy, deodorant properties, antifouling properties, insect repellent properties, and antibacterial properties can also be carried on the skin layer 3 to the extent that does not interfere with the present invention. Moreover, what carried | supported the deodorizer previously in the nonwoven fabric in the case of making the nonwoven fabric impregnate an adhesive agent to make the adhesive layer 4 with air permeability may be used.

また、消臭剤としては、特に限定されないが、活性炭やゼオライトのような多孔質体で臭気を吸着するものや、金属酸化物のように臭気を分解するもの、あるいはそれらを組み合わせたものが挙げられる。中でも、本発明の座席シート用表皮材は、通気性に優れることから、多孔質無機物質と、金属酸化物と、ポリアミン化合物を担持した無機ケイ素化合物とを含む消臭組成物を担持さすのが好ましい。該消臭組成物は、アルデヒド類や、アンモニア等の塩基性ガス、酢酸等の酸性ガス、硫化水素、メチルメルカプタン等の硫黄系ガスの消臭に有効で、座席シートに付与することによって、立体編物の優れた通気性により、消臭フィルターのような働きをなして、自然な空気流のうちに室内空気を浄化することができる。   In addition, the deodorant is not particularly limited, and examples thereof include those that adsorb odors with porous bodies such as activated carbon and zeolite, those that decompose odors such as metal oxides, or combinations thereof. It is done. Among them, the skin material for seats of the present invention is excellent in air permeability, and therefore carries a deodorant composition containing a porous inorganic substance, a metal oxide, and an inorganic silicon compound carrying a polyamine compound. preferable. The deodorizing composition is effective for deodorizing aldehydes, basic gases such as ammonia, acidic gases such as acetic acid, sulfur-based gases such as hydrogen sulfide and methyl mercaptan, and is applied to a seat sheet to provide a three-dimensional structure. Due to the excellent air permeability of the knitted fabric, it can act like a deodorizing filter and purify indoor air in a natural air flow.

また、立毛布帛としては特に限定されず、パイルのあるモケットや起毛織物、起毛編物等の座席シートの表皮材として通常使用されているものでよい。意匠性のある立毛布帛を立体編物の基材層に積層することで、立体編物だけでは表現できない様々な意匠性が加えられ、座席シート用表皮材として良好なものとすることができる。   The raised fabric is not particularly limited, and may be one that is usually used as a skin material for seat sheets such as piled moquettes, raised fabrics, and raised knitted fabrics. By stacking a raised fabric having design properties on a base material layer of a three-dimensional knitted fabric, various design properties that cannot be expressed only by the three-dimensional knitted fabric are added, and the skin material for a seat sheet can be made favorable.

つぎに本発明の座席シート用表皮材について具体的な実施例について説明する。なお、この発明の座席シート用表皮材は、実施例に限定されるものではなく、使用した材料は以下のものとした。   Next, specific examples of the skin material for seats of the present invention will be described.
