　本発明を実施するための形態を以下に説明する。 DETAILED DESCRIPTION Embodiments for carrying out the present invention will be described below.
（第１の実施の形態）
　図１は、本発明を適用した第１の実施形態の流体回路付き複合布帛１を例示する平面図である。図２は、本実施形態の流体回路付き複合布帛１の側面図である。図３は、本実施形態の流体回路付き複合布帛１のＥ－Ｅ線断面図である。本実施形態の流体回路付き複合布帛１は、合繊編物からなる繊維基布２の片面に熱融着性フィルム３がラミネートされた布帛４を２枚重ね合わせて、所定の回路形状を有する金型１０を用いた熱プレスによって複合布帛とするとともに流動性媒体を通すための流体回路５を形成している（図１～図３）。 (First embodiment)
FIG. 1 is a plan view illustrating a composite fabric 1 with a fluid circuit according to a first embodiment to which the present invention is applied. FIG. 2 is a side view of the composite fabric 1 with a fluid circuit of the present embodiment. FIG. 3 is a cross-sectional view taken along line EE of the composite fabric 1 with a fluid circuit according to the present embodiment. A composite fabric 1 with a fluid circuit of the present embodiment is a mold having a predetermined circuit shape obtained by superposing two fabrics 4 laminated with a heat-fusible film 3 on one side of a fiber base fabric 2 made of synthetic fiber knitted fabric. A fluid circuit 5 for forming a composite fabric and allowing a fluid medium to pass through is formed by hot pressing using No. 10 (FIGS. 1 to 3).
　本実施形態では、前記複合布帛１は、前記流体回路５の入口には、連結管１０１が連結固定されており、前記流体回路５の出口には、連結管１０２が連結固定されており、連結管１０１と連結管１０２の間には既知のポンプ１００が接続され、流体９が流体回路５内を流動する構成となっている（図１、図３）。ここでは、連結管１０１，１０２はポリエステル製であり、ポリエステル糸が編成された繊維基布２と熱融着され固定されている。上記以外の方法としては、連結管１０１，１０２を繊維基布２と接着剤にて接着してもよいし、熱収縮チューブ等の連結固定手段を用いて固定してもよい。 In this embodiment, the composite fabric 1 has a connecting pipe 101 connected and fixed to the inlet of the fluid circuit 5, and a connecting pipe 102 connected and fixed to the outlet of the fluid circuit 5. A known pump 100 is connected between the pipe 101 and the connecting pipe 102 so that the fluid 9 flows in the fluid circuit 5 (FIGS. 1 and 3). Here, the connecting pipes 101 and 102 are made of polyester, and are thermally fused and fixed to the fiber base fabric 2 knitted with polyester yarn. As a method other than the above, the connection pipes 101 and 102 may be bonded to the fiber base fabric 2 with an adhesive, or may be fixed using a connection fixing means such as a heat shrinkable tube.
　図３に示すように、流体回路５は断面が楕円形状又は円形状となり、流体回路５以外の箇所は断面が板形状となる。これは、流体回路５以外の箇所が熱プレスされているが、流体回路５が熱プレスされていないことで、流体回路５を構成する内側の熱融着性フィルム３と外側の繊維基布２のストレッチ性並びに伸縮性が良好な状態が維持されるとともに、流体回路５を構成しないエリアのストレッチ性並びに伸縮性が抑えられることによる。 3, the fluid circuit 5 has an elliptical or circular cross section, and portions other than the fluid circuit 5 have a plate shape in cross section. This is because the portions other than the fluid circuit 5 are hot-pressed, but the fluid circuit 5 is not hot-pressed, so that the inner heat-fusible film 3 and the outer fiber base fabric 2 constituting the fluid circuit 5 are provided. This is because the stretchability and stretchability of the fluid circuit 5 are maintained, and the stretchability and stretchability of the area not constituting the fluid circuit 5 are suppressed.
　図４は、本発明の流体回路付き複合布帛１の製造手順を示すフローチャート図である。本実施形態の流体回路付き複合布帛１の製造手順は、熱プレス（符号Ｓ１１）、裁断処理（符号Ｓ１２）の各工程からなる（図４）。 FIG. 4 is a flowchart showing the manufacturing procedure of the composite fabric 1 with a fluid circuit of the present invention.

　図５は、本発明の流体回路付き複合布帛を熱プレスする金型１０を例示する平面図である。図６は、前記金型１０のＥ－Ｅ線断面図である。本実施形態の金型１０は、耐熱性の硬質金属製であり、例えばアルミニウム、鉄、ステンレス、ニッケル合金、銅合金からなる。前記金型１０の平面１４には、前記流体回路５を形成するための凹部１５が彫り込んである（図５、図６）。金型１０は、同じ形状のものを２つ向かい合わせて熱圧着する構成となっている。すなわち、繊維基布２の片面に熱融着性フィルム３がラミネートされた布帛４を、その熱融着性フィルム３の側を向かい合わせに前記布帛４を２枚重ね合わせて金型１０と金型１０とで挟み、所定個所（図５に示す例では平面１４と対応する箇所）を熱融着処理することによって複合布帛とするとともに流動性媒体９を通すための流体回路５を形成する。本実施形態では、前記熱プレスの際に、熱効率を高めるため高周波熱融着方式としている。本実施形態によれば、複合布帛の形成と、流体回路の形成を、同時形成することが容易である。 FIG. 5 is a plan view illustrating a mold 10 for hot pressing the composite fabric with a fluid circuit of the present invention. FIG. 6 is a cross-sectional view of the mold 10 taken along the line EE. The mold 10 of the present embodiment is made of a heat-resistant hard metal, and is made of, for example, aluminum, iron, stainless steel, nickel alloy, or copper alloy. A concave portion 15 for forming the fluid circuit 5 is engraved on the flat surface 14 of the mold 10 (FIGS. 5 and 6). The mold 10 has a configuration in which two of the same shape face each other and are thermocompression bonded. That is, a fabric 4 in which the heat-fusible film 3 is laminated on one side of the fiber base fabric 2 is overlapped with the two fabrics 4 facing the heat-fusible film 3 side so that the mold 10 and the mold 10 A fluid circuit 5 for forming a composite fabric and passing the fluid medium 9 is formed by heat-sealing a predetermined portion (a portion corresponding to the flat surface 14 in the example shown in FIG. 5) between the mold 10. In the present embodiment, a high frequency heat fusion method is used in order to increase the thermal efficiency during the hot pressing. According to the present embodiment, it is easy to simultaneously form the composite fabric and the fluid circuit.
　図７は、本発明の流体回路付き複合布帛を熱プレスする金型１０の他の例を示す平面図である。図８は、前記金型１０のＡ－Ａ線断面図である。本実施形態の金型１０は、耐熱性の硬質金属製であり、例えばアルミニウム、鉄、ステンレス、ニッケル合金、銅合金からなる。前記金型１０には、前記流体回路５を形成するための凹部１５が彫り込んであり、凹部１５の両側が突出した凸部１６となっており、凸部１６の外側が僅かに窪んだ窪み部１４となっている（図７、図８）。窪み部１４は、金型１０の広い範囲で均一に窪んでおり、平面状となっている。金型１０は、同じ形状のものを２つ向かい合わせて熱圧着する構成となっている。すなわち、繊維基布２の片面に熱融着性フィルム３がラミネートされた布帛４を、その熱融着性フィルム３の側を向かい合わせに前記布帛４を２枚重ね合わせて金型１０と金型１０とで挟み、所定個所（図７に示す例では凸部１６と対応する箇所）を熱融着処理することによって複合布帛とするとともに流動性媒体９を通すための流体回路５を形成する。本実施形態では、前記熱プレスの際に、熱効率を高めるため高周波熱融着方式としている。本実施形態によれば、複合布帛の形成と、流体回路の形成を、同時形成することが容易である。 FIG. 7 is a plan view showing another example of the mold 10 for hot pressing the composite fabric with a fluid circuit of the present invention. FIG. 8 is a cross-sectional view of the mold 10 along the line AA. The mold 10 of the present embodiment is made of a heat-resistant hard metal, and is made of, for example, aluminum, iron, stainless steel, nickel alloy, or copper alloy. A concave portion 15 for forming the fluid circuit 5 is engraved in the mold 10, and convex portions 16 projecting on both sides of the concave portion 15, and a concave portion in which the outer side of the convex portion 16 is slightly recessed. 14 (FIGS. 7 and 8). The depression 14 is uniformly depressed over a wide range of the mold 10 and has a planar shape. The mold 10 has a configuration in which two of the same shape face each other and are thermocompression bonded. That is, a fabric 4 in which the heat-fusible film 3 is laminated on one side of the fiber base fabric 2 is overlapped with the two fabrics 4 facing the heat-fusible film 3 side so that the mold 10 and the mold 10 A fluid circuit 5 for forming a composite fabric and passing the fluid medium 9 is formed by heat-sealing a predetermined part (a part corresponding to the convex part 16 in the example shown in FIG. 7) between the mold 10. . In the present embodiment, a high frequency heat fusion method is used in order to increase the thermal efficiency during the hot pressing. According to the present embodiment, it is easy to simultaneously form the composite fabric and the fluid circuit.
　図７と図８に示す金型１０を用いた場合、流体回路５の周辺部で凸部１６に対応した箇所のみが熱プレスされる。このため、流体回路５が熱プレスされていないことで、流体回路５を構成する内側の熱融着性フィルム３と外側の繊維基布２のストレッチ性並びに伸縮性が良好な状態が維持されるとともに、流体回路５の周辺部で凸部１６に対応した箇所のストレッチ性並びに伸縮性が抑えられ、それ以外のエリアのストレッチ性並びに伸縮性が良好な状態が維持されるので、布帛全体としてはストレッチ性並びに伸縮性が高い状態の流体回路付き複合布帛が得られる。 When the mold 10 shown in FIGS. 7 and 8 is used, only the portion corresponding to the convex portion 16 in the peripheral portion of the fluid circuit 5 is hot-pressed. For this reason, the fluid circuit 5 is not hot-pressed, so that a state where the stretchability and the stretchability of the inner heat-fusible film 3 and the outer fiber base fabric 2 constituting the fluid circuit 5 are good is maintained. At the same time, the stretchability and stretchability of the portion corresponding to the convex portion 16 in the peripheral portion of the fluid circuit 5 are suppressed, and the stretchability and stretchability of other areas are maintained in a good state. A composite fabric with a fluid circuit having high stretchability and high stretchability is obtained.
　本実施形態では、図１に示すように、符号５にて示す前記回路形状の主要部が、流線形を連続的に組み合わせた蛇行形状となっている。本実施形態によれば、流体９を流動させる際の抵抗が少なくてスムースな流動となるとともに、複合布帛１における流体回路５の密度を高めることが容易となる。 In this embodiment, as shown in FIG. 1, the main part of the circuit shape indicated by reference numeral 5 has a meandering shape in which streamlines are continuously combined. According to the present embodiment, the resistance when the fluid 9 is caused to flow is small and the fluid 9 can be smoothly flowed, and the density of the fluid circuit 5 in the composite fabric 1 can be easily increased.
