布帛に帯電防止性を与える方法としては、従来から様々な方法が提案されている。例えば帯電防止性を有する界面活性剤を繊維に付着させたり、布帛を構成する繊維に導電性繊維を混入したり、パイル布帛においては、バッキング層内にカーボンを配合することにより帯電防止性を付与する方法等が多く提案されている。 Various methods have conventionally been proposed as methods for imparting antistatic properties to fabrics. For example, a surfactant having antistatic properties is attached to the fibers, conductive fibers are mixed into the fibers constituting the fabric, and in pile fabrics, antistatic properties are imparted by adding carbon to the backing layer. Many methods have been proposed.
一方、自動車等の乗員が自動車の乗降時に静電気の放電による強い衝撃を受けることを防止する方法として特許文献１においては、ドア開閉用の取っ手部分とドアの鉄板部分を電線で結び、人体に貯まった静電気を自動車の金属部に流出するようにして、人体が強い衝撃を受けることを防止する方法を開示している。 On the other hand, as a method for preventing a passenger such as an automobile from receiving a strong impact due to static electricity discharge when getting on and off the automobile, the handle portion for opening and closing the door and the iron plate portion of the door are connected by an electric wire and stored in the human body. A method for preventing the human body from receiving a strong impact by discharging static electricity to the metal part of the automobile is disclosed.
また、特許文献２においては、自動車のドアトリムや天井、シートカバーなどのワディング材に自己放電により静電気中和機能を発揮する除電繊維を混入した自動車内装用表面材を開示している。 Patent Document 2 discloses a surface material for automobile interior in which a neutralizing fiber that exhibits a static electricity neutralizing function by self-discharge is mixed into a wadding material such as an automobile door trim, ceiling, or seat cover.
しかしながら上記の方法では、未だ十分な帯電防止性能や除電性能の付与はなされておらず、低湿度下では静電気の放電による衝撃が残り、またコストの高いものとなる難点があった。 However, in the above method, sufficient antistatic performance and static elimination performance have not been imparted yet, and there has been a problem that impact due to electrostatic discharge remains at low humidity and the cost is high.
本発明は、自動車等におけるドア用の内装布帛に使用する布帛であって、冬場の低湿度環境であっても、乗員が自動車の乗降時に該布帛に軽く触れるだけで、帯電した人体が自動車の鉄板等の金属に接する時に受ける、強い衝撃から身を守るものである。 The present invention is a fabric used for an interior fabric for a door in an automobile or the like, and even in a low humidity environment in winter, the occupant can touch the fabric lightly when getting on and off the vehicle, and the charged human body can be It protects itself from strong impacts when it comes into contact with metal such as iron plates.
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、ドア用の内装布帛にイオン伝導剤と浸透剤を含む溶剤を塗布することで上記課題を克服することができ、本発明に到達した。前記目的を達成するために、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 can overcome the above problems by applying a solvent containing an ionic conductive agent and a penetrating agent to the interior fabric for doors. The invention has been reached. In order to achieve the above object, the present invention provides the following means.
［１］車両ドア用の内装布帛であって、内装布帛の体積抵抗値を１０７〜１０１０Ωにしたことを特徴とする車両ドア用の内装布帛。 [1] An interior fabric for vehicle doors, wherein the interior fabric has a volume resistance of 10 7 to 10 10 Ω.
［２］前記車両ドア用の内装布帛において、浸透剤と共にイオン伝導剤を含む溶剤を塗布し、内装布帛に導電層を設けたことを特徴とする前項１に記載の車両ドア用の内装布帛。 [2] The interior fabric for vehicle doors according to item 1 above, wherein the interior fabric for vehicle doors is formed by applying a solvent containing an ionic conductive agent together with a penetrant, and providing a conductive layer on the interior fabric.
［３］前記車両ドア用の内装布帛において、内装布帛の裏面側から浸透剤と共にイオン伝導剤を含む溶剤を塗布し、内装布帛の表面側には、撥水加工を施したことを特徴とする前項１又は２に記載の車両ドア用の内装布帛。 [3] The interior fabric for a vehicle door is characterized in that a solvent containing an ionic conductive agent is applied together with a penetrant from the back side of the interior fabric, and a water repellent finish is applied to the surface side of the interior fabric. 3. An interior fabric for vehicle doors according to item 1 or 2.
［４］前記車両ドア用の内装布帛において、前記イオン伝導剤が、内装布帛に対して０．１〜１０重量％担持されていることを特徴とする前項１〜３のいずれか１項に記載の車両ドア用の内装布帛。 [4] The interior fabric for a vehicle door, wherein the ionic conductive agent is supported by 0.1 to 10% by weight with respect to the interior fabric. Interior fabric for vehicle doors.
［１］の発明では、体積抵抗値を１０７〜１０１０Ωにした車両ドア用の内装布帛であるので、内装布帛に人が触れることにより人体に帯電した静電気は、徐々に放電され、放電による強い衝撃を受けることを防止することができる。 In the invention [1], since the decorated fabric for a vehicle door in which the volume resistivity to 10 7 to 10 10 Omega, the static electricity charged in a human body by touching a person interior fabric, is gradually discharged, the discharge It is possible to prevent a strong shock from being received.
［２］の発明では、車両ドア用の内装布帛に浸透剤と共にイオン伝導剤を含む溶剤を塗布しているので、イオン伝導剤が内装布帛の内部にまで入り込んで、耐久性のある導電効果に優れた車両ドア用の内装布帛とすることができる。 In the invention of [2], since a solvent containing an ionic conductive agent together with a penetrant is applied to the interior fabric for a vehicle door, the ionic conductive agent penetrates into the interior fabric, resulting in a durable conductive effect. It can be set as the outstanding interior fabric for vehicle doors.
［３］の発明では、車両ドア用の内装布帛の表面に撥水加工を施し、裏面にイオン伝導剤を含む溶剤を塗布しているので、導電性能と撥水性能を具備した繊維布帛とすることができる。通常撥水加工を施すと導電性能は低下するので、撥水加工と導電加工は同時にすることはなかったが、導電加工が繊維布帛の裏面からの加工で効果を発揮することが確認できたことから表面に撥水加工することにより、導電性能と撥水性能の両効果を発揮する車両ドア用の内装布帛とすることができる。撥水加工が施されているので、人が触れても汚れにくい車両ドア用の内装布帛とすることができる。 In the invention of [3], a water-repellent finish is applied to the surface of the interior fabric for the vehicle door, and a solvent containing an ionic conductive agent is applied to the back surface, so that the fiber fabric has a conductive performance and a water-repellent performance. be able to. Normally, when water-repellent processing is performed, the conductive performance decreases, so water-repellent processing and conductive processing were not performed at the same time, but it was confirmed that conductive processing was effective in processing from the back side of the fiber fabric. By applying water-repellent treatment to the surface, it is possible to provide an interior fabric for a vehicle door that exhibits both effects of conductivity and water-repellency. Since it is water repellent, it can be used as an interior fabric for vehicle doors that is difficult to get dirty even when touched by a person.
［４］の発明では、イオン伝導剤が、内装布帛に対して０．１〜１０重量％担持されているので、十分な導電効果のある車両ドア用の内装布帛とすることができる。 In the invention of [4], since the ion conductive agent is supported in an amount of 0.1 to 10% by weight with respect to the interior fabric, the interior fabric for a vehicle door having a sufficient conductive effect can be obtained.
自動車等の乗員が乗降時にドアの金属部分に触れたとき、人体に帯電した静電気が瞬時に放電することから強い衝撃を受けることがあり、特に湿度の低い冬季にはその頻度が多い。本発明は、人体に帯電した静電気が瞬時に放電するのを防ぎ、徐々に放電するようにしたもので、ドア用の内装布帛に一旦触れて、人体に帯電した静電気を除電し、ドアの開閉時の放電による強い衝撃を防ぐものである。 When an occupant such as an automobile touches a metal part of a door when getting on and off, the static electricity charged on the human body may be discharged instantly, and may receive a strong impact, particularly in the winter when the humidity is low. The present invention prevents the static electricity charged on the human body from being instantaneously discharged and gradually discharges it. By touching the interior fabric for the door, the static electricity charged on the human body is removed, and the door is opened and closed. It prevents strong impacts caused by electrical discharge.
この発明においては、車両ドア用の内装布帛の体積抵抗値を１０７〜１０１０Ωにする必要があるがあり、まず内装布帛に導電加工を施さなければならない。内装布帛に導電性能を付与する方法は種々挙げらるが、特に湿度の低い環境下でも導電性能を得られる方法として、浸透剤と共にイオン伝導剤を含む溶剤を塗布する方法を挙げられる。イオン伝導剤として、例えば、ポリオキシアルキレン側鎖を有するオルガノポリシロキサン中に電解質塩化合物を溶解含有している帯電防止組成物を挙げることができる。オルガノポリシロキサンに側鎖として結合しているポリオキシアルキレン中に電解質塩化合物がイオン溶解し、このイオンが導電性発現に寄与していると考えられ、湿度の影響が少なく効率的に導電性を得るものである。（本発明では丸菱油化工業株式会社製のイオン伝導性ポリマーＰＣ７０６０をイオン伝導剤として使用した。） In the present invention, the volume resistance value of the interior fabric for the vehicle door needs to be 10 7 to 10 10 Ω, and first, the interior fabric must be subjected to conductive processing. There are various methods for imparting conductive performance to the interior fabric, and as a method for obtaining conductive performance even in a low humidity environment, there is a method of applying a solvent containing an ionic conductive agent together with a penetrant. Examples of the ion conductive agent include an antistatic composition in which an electrolyte salt compound is dissolved and contained in an organopolysiloxane having a polyoxyalkylene side chain. The electrolyte salt compound is ion-dissolved in polyoxyalkylene bonded as a side chain to the organopolysiloxane, and this ion is thought to contribute to the development of conductivity. To get. (In the present invention, ion conductive polymer PC7060 manufactured by Maruhishi Oil Chemical Co., Ltd. was used as the ion conductive agent.)
導電層は、内装布帛に、イオン伝導剤を含む溶剤を塗布して作成する。塗布する方法は、スプレー法、ロールコート法、ブラシやはけによる塗布方法を挙げられるが、均一な導電層を形成するにはスプレー法が好適である。 The conductive layer is formed by applying a solvent containing an ionic conductive agent to the interior fabric. Examples of the application method include a spray method, a roll coating method, and an application method using a brush or a brush. The spray method is suitable for forming a uniform conductive layer.
また、上記イオン伝導剤の内装布帛への付与量は、内装布帛素材に対して０．１〜１０重量％とするのが好ましい。０．１重量％未満では、導電効果が十分に得られなくなり、一方１０重量％を超えても付与量の増加に見合うより以上の効果が得られず、またコスト高となって経済的に不利であるし、内装布帛の物性や風合いを低下させることがあるので、好ましくない。中でも内装布帛素材に対して０．５〜５重量％とするのが一層好ましい。 The amount of the ion conductive agent applied to the interior fabric is preferably 0.1 to 10% by weight relative to the interior fabric material. If the amount is less than 0.1% by weight, a sufficient conductive effect cannot be obtained. On the other hand, if the amount exceeds 10% by weight, an effect more than that corresponding to the increase in the applied amount cannot be obtained, and the cost is increased. It is not preferable because the physical properties and texture of the interior fabric may be lowered. Among these, the content is more preferably 0.5 to 5% by weight based on the interior fabric material.
上記のようにイオン伝導剤を内装布帛に付与した後に内装布帛を乾燥させるが、乾燥手段は特に限定されないが、効率を考慮すると、加熱処理により乾燥させるのが望ましい。前記加熱処理の温度は、１００〜１８０℃とするのが好ましい。この温度での加熱処理により、導電組成物の布帛への固着性を高めて、導電性能の耐久性を一段と向上せしめることができる。 As described above, the interior fabric is dried after the ion conductive agent is applied to the interior fabric. The drying means is not particularly limited, but it is desirable to dry by heat treatment in consideration of efficiency. The temperature of the heat treatment is preferably 100 to 180 ° C. By heat treatment at this temperature, the adhesiveness of the conductive composition to the fabric can be increased, and the durability of the conductive performance can be further improved.
また、本発明においては、内装布帛に浸透剤と共にイオン伝導剤を含む溶剤を塗布し、内装布帛内に導電層を設けるようにする方がよい。さらに、内装布帛の表面近くにイオン伝導剤からなる導電層を形成するほうが、内装布帛の表面に帯電する電荷を除電する効果は大きくなることから好ましい。浸透剤としてはアルコール類、非イオン界面活性剤、アニオン界面活性剤等を挙げられるが、これらに限定されるものではない。 Moreover, in this invention, it is better to apply | coat the solvent containing an ionic conductive agent with a penetrating agent to an interior fabric, and to provide a conductive layer in an interior fabric. Furthermore, it is preferable to form a conductive layer made of an ionic conductive agent near the surface of the interior fabric because the effect of eliminating the charge charged on the surface of the interior fabric is increased. Examples of the penetrating agent include alcohols, nonionic surfactants, anionic surfactants and the like, but are not limited thereto.
また、本発明においては、内装布帛の表面には撥水加工を施し、裏面にはイオン伝導剤を含む溶剤を塗布してもよい。通常、導電加工した布帛に撥水加工を施すと、導電性能は低下してしまうことから、撥水加工と導電加工は同時に行うことはなかったが、本発明における導電加工は、内装布帛の裏面からの加工で効果を十分発揮することが確認できることから、さらに表面側に撥水加工を行うことにより、導電性能と撥水性能の両効果を発揮する車両ドア用の内装布帛とすることができる。撥水剤としてはワックス系撥水剤、シリコン系撥水剤、フッ素系撥水剤等を挙げられるが、これらに限定されるものではない。 In the present invention, the surface of the interior fabric may be water-repellent and the back surface may be coated with a solvent containing an ionic conductive agent. Normally, when water-repellent processing is performed on a conductively processed fabric, the conductive performance deteriorates. Therefore, the water-repellent processing and the conductive processing were not performed at the same time, but the conductive processing in the present invention is performed on the back surface of the interior fabric. Since it can be confirmed that the effect is sufficiently exhibited by processing from the above, by performing water-repellent treatment on the surface side, it can be an interior fabric for vehicle doors that exhibits both effects of conductivity and water-repellent performance. . Examples of the water repellent include, but are not limited to, a wax-based water repellent, a silicon-based water repellent, and a fluorine-based water repellent.
また、本発明は、内装布帛における体積抵抗値が２０℃湿度３０％において１０１０Ω以下である。一般に物質の体積抵抗値を測定して帯電性を評価することが多く、なにも処理されていないＰＥやＰＰのプラスチックフィルムの体積抵抗値は１０１５Ω〜１０１７Ω程度あり、１０１０Ω以下であれば静電気障害は発生しにくいといわれている。本発明は、イオン伝導剤を含む溶剤を内装布帛に塗布して導電層を設けることから、２０℃湿度３０％の乾燥した条件下において体積抵抗値１０１０Ω以下を確保できる。 In the present invention, the volume resistance value of the interior fabric is 10 10 Ω or less at 20 ° C. and 30% humidity. In general, the volume resistance value of a substance is often measured to evaluate the charging property, and the volume resistance value of PE or PP plastic film that has not been treated at all is about 10 15 Ω to 10 17 Ω, and 10 10 Ω. It is said that electrostatic damage is less likely to occur if In the present invention, since a conductive layer is provided by applying a solvent containing an ionic conductive agent to the interior fabric, a volume resistance value of 10 10 Ω or less can be secured under dry conditions of 20 ° C. and 30% humidity.
本発明における導電加工の対象となる内装布帛としては、特に限定されるものではなくどのようなものでも使用できる。例えば、ビロード、別珍、コール天、カーペット、モケット、立毛メリヤス、起毛トリコット、シンカーパイル、シングルラッセル、ダブルラッセル、タフティングパイル布帛等のパイル布帛や、トリコット、ジャージ、インレイニット、紋織物、ドビー織物等の製編織した布地の他、ニードルパンチ、スパンボンド不織布等の不織布などを例示できる。 The interior fabric to be subjected to conductive processing in the present invention is not particularly limited, and any fabric can be used. For example, pile fabrics such as velvet, extraordinary, cauldron, carpet, moquette, napped knitted fabric, raised tricot, sinker pile, single raschel, double raschel, tufting pile fabric, tricot, jersey, inlay knit, patterned fabric, dobby fabric In addition to knitted and woven fabrics such as, non-woven fabrics such as needle punches and spunbond nonwoven fabrics can be exemplified.

For example, polyester fiber, acrylic fiber, nylon fiber, polypropylene fiber, polyvinyl chloride fiber, vinylon fiber, polyethylene fiber, polyurethane fiber. The thing which consists of etc. can be mentioned.
内装布帛表面をパイルとしたパイル布帛では、毛抜け防止の為にバッキング加工が行われることが多いが、本発明では、内装布帛の裏面に本発明の導電加工を行ったあとに、内装布帛の裏面にバッキング加工を施すようにしなければならない。バッキング加工を施したあとに本発明の導電加工を行っても、内装布帛表面に優れた導電効果を得ることはできない。 In a pile fabric having an interior fabric surface as a pile, a backing process is often performed to prevent hair loss. In the present invention, after the conductive process of the present invention is performed on the back surface of the interior fabric, The back side must be backed. Even if the conductive processing of the present invention is performed after the backing processing, an excellent conductive effect cannot be obtained on the interior fabric surface.
バッキング層に使用する樹脂としては特に限定しないが、ゴム及び合成樹脂から選択される１種または２種以上の高分子成分を含むもので、高分子成分としては、ＳＢＲ（スチレン−ブタジエン共重合体）、ＮＢＲ（アクリロニトリル−ブタジエン共重合体）、ＭＢＲ（メタクリル酸メチル−ブタジエン共重合体）、アクリル樹脂エマルジョン、ＥＶＡ（エチレン−酢酸ビニル共重合体）天然ゴム等から選らばれる。 Although it does not specifically limit as resin used for a backing layer, It contains 1 type, or 2 or more types of polymer components selected from rubber | gum and a synthetic resin, As a polymer component, it is SBR (styrene-butadiene copolymer). ), NBR (acrylonitrile-butadiene copolymer), MBR (methyl methacrylate-butadiene copolymer), acrylic resin emulsion, EVA (ethylene-vinyl acetate copolymer) natural rubber, and the like.
一般的にバッキング剤には無機充填剤が添加されるが、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。また、必要に応じて本発明の効果を妨げない範囲において抗菌剤、防虫剤、消臭剤、難燃剤、防炎剤等の各種添加剤をバッキング剤に配合することもできる。 In general, an inorganic filler is added to the backing agent, but an inorganic filler may also be added in the present invention. Although it does not specifically limit as an inorganic filler, A calcium carbonate, aluminum hydroxide, magnesium hydroxide, a silica etc. can be illustrated. Moreover, various additives, such as an antibacterial agent, an insecticide, a deodorant, a flame retardant, and a flameproofing agent, can also be mix | blended with a backing agent in the range which does not prevent the effect of this invention as needed.
また、本発明においては、車両ドア用の内装布帛としているが、ドア以外の例えば天井やシートカバー等の一部に本発明の内装布帛を装着し、降車時に該内装布帛に一旦触れても、人体に帯電した静電気は除電されて、放電による強い衝撃を防ぐことができる。 Further, in the present invention, although it is an interior fabric for a vehicle door, even if the interior fabric of the present invention is attached to a part of the ceiling, a seat cover, etc. other than the door, and the interior fabric is touched once when getting off, The static electricity charged on the human body is neutralized, and strong impact due to discharge can be prevented.

<Comparative example 2>
In the same fiber fabric as in Example 1, an acrylic resin emulsion was applied to the back surface of the ground texture with an application amount of 90 g / m 2 (solid component) to form a backing layer, and then an ionic conductive agent (Maruhishi Oil Chemical Co., Ltd.). An application amount of 4.0 g / m 2 of an aqueous solution containing an aqueous solution in which an ion conductive polymer PC7060 manufactured by Co., Ltd. and a penetrant (isopropyl alcohol manufactured by Nishimura Co., Ltd.) are mixed one-to-one.
An interior fabric for a vehicle door was obtained in the same manner as in Example 1 except that the coating was applied so as to be (solid component). The volume resistance value of the interior fabric was 10 15 Ω. Next, when the interior fabric was fitted into a fitting portion of an automobile door prepared experimentally and a discharge impact test was performed, there was a strong impact.
＜参考例＞
実施例１と同じ繊維布帛において、イオン伝導剤（丸菱油化工業株式会社製のイオン伝導性ポリマーＰＣ７０６０）と、浸透剤（西村株式会社製のイソプロピルアルコール）を１対１に配合した水溶液を塗布量３８ｇ／ｍ２
（固形成分）となるようにスプレー塗布した以外は実施例１と同様にして、車両ドア用の内装布帛を得た。内装布帛の体積抵抗値は、１０６Ωであった。次に試験的に作成した自動車ドアの嵌め込み部分に該内装布帛を嵌め込んで、放電衝撃試験をおこなったところ、衝撃はなかった。
<Reference example>
In the same fiber fabric as in Example 1, an aqueous solution in which an ion conductive agent (ion conductive polymer PC7060 manufactured by Maruhishi Oil Chemical Co., Ltd.) and a penetrant (isopropyl alcohol manufactured by Nishimura Co., Ltd.) are mixed 1: 1. Application amount 38 g / m 2
An interior fabric for a vehicle door was obtained in the same manner as in Example 1 except that the coating was applied so as to be (solid component). The volume resistance value of the interior fabric was 10 6 Ω. Next, when the interior fabric was fitted into a fitting portion of an automobile door prepared experimentally and a discharge impact test was conducted, there was no impact.
また、上記のようにイオン伝導剤を配合した実施例１〜４の内装布帛は、低湿度条件（２０℃、３０％ＲＨ）において体積抵抗値は、１０７Ω〜１０８Ωとなって、放電衝撃試験をおこなっても、衝撃はなかった。 The interior fabric of Examples 1 to 4 was blended ion conductive agent as described above, the low humidity condition (20 ℃, RH 30%) volume resistivity at, become 10 7 Ω~10 8 Ω, There was no impact in the discharge impact test.
これに対し、導電層を構成するイオン伝導剤の塗布のない比較例１の布帛は、体積抵抗値が１０１５Ωとなり、放電衝撃試験では、強い衝撃のあるものとなった。また、比較例２では、導電層がバッキング層の下側に形成されることになり、体積抵抗値に影響しないので体積抵抗値が１０１５Ωとなり、放電衝撃試験でも、強い衝撃のあるものとなった。 On the other hand, the fabric of Comparative Example 1 without application of the ionic conductive agent constituting the conductive layer had a volume resistance value of 10 15 Ω and had a strong impact in the discharge impact test. In Comparative Example 2, the conductive layer is formed below the backing layer and does not affect the volume resistance value. Therefore, the volume resistance value is 10 15 Ω, and there is a strong impact in the discharge impact test. became.
また、イオン伝導剤が繊維布帛素材に対して１０重量％を超えて塗布された参考例では、帯電防止性能は向上するものの硬くなってしまい、布帛本来の優れた風合いを得ることはできなかった。 In addition, in the reference example in which the ion conductive agent was applied in an amount exceeding 10% by weight with respect to the fiber fabric material, the antistatic performance was improved, but it became hard, and it was not possible to obtain an excellent texture inherent to the fabric. .
この発明に係る車両ドア用の内装布帛は、自動車以外にも、静電気を徐々に放電する除電布帛として応用される範囲は広い。 The interior fabric for a vehicle door according to the present invention has a wide range of applications as a static elimination fabric that gradually discharges static electricity in addition to an automobile.
