Surprisingly, carbon black also has antistatic properties. At that time, as the antistatic property, the frictional voltage is preferably 3500 V or less (more preferably 3000 V or less).
前記赤外線吸収剤は、優れた耐久性を得る上で、赤外線吸収剤単独ではなく樹脂とともに基布に付着し、赤外線吸収剤を含む樹脂層が基布に積層されていることが好ましい。
その際、樹脂層に含まれる赤外線吸収剤の含有量としては、樹脂層の樹脂重量対比（固形分比）０．５重量％以上（より好ましくは０．５〜３０重量％）であることが好ましい。赤外線吸収剤の含有量が０．５重量％未満の場合、十分な蓄熱性が得られないおそれがある。
In order to obtain excellent durability, the infrared absorber is preferably attached to the base fabric together with the resin instead of the infrared absorber alone, and a resin layer containing the infrared absorber is laminated on the base fabric.
At that time, the content of the infrared absorber contained in the resin layer is 0.5% by weight or more (more preferably 0.5 to 30% by weight) of the resin weight of the resin layer (solid content ratio). preferable. When the content of the infrared absorber is less than 0.5% by weight, sufficient heat storage property may not be obtained.
また、前記樹脂層に、シリカ粒子、酸化チタン粒子などの無機微粒子を含ませてもよい。特に、平均１次粒子径（ＢＥＴ法により測定される球相当径）が１〜５０μｍのシリカ粒子を、樹脂層の樹脂重量対比（固形分比）１．０重量％以上（より好ましくは１．０〜１０．０重量％）含ませると、樹脂層に露出（突起）した前記無機微粒子により人体（肌）と布帛との接触面積が小さくなり摩擦係数が小さくなり、さらに優れた肌触りが得られ好ましい。 The resin layer may contain inorganic fine particles such as silica particles and titanium oxide particles. In particular, silica particles having an average primary particle diameter (sphere equivalent diameter measured by the BET method) of 1 to 50 μm are 1.0% by weight or more (more preferably 1.% by weight) compared to the resin weight of the resin layer (solid content ratio). 0 to 10.0% by weight), the inorganic fine particles exposed (protrusions) on the resin layer reduce the contact area between the human body (skin) and the fabric, reduce the coefficient of friction, and provide an even better feel. preferable.
また、驚くべきことに、樹脂層に前記無機微粒子を含有させることにより布帛の蓄熱性が向上する。その理由についてはまだ明らかにされていないが、樹脂層に含まれる赤外線吸収剤と前記無機微粒子との相乗作用により、樹脂層に前記無機微粒子が露出（突起）しやすくなり、かかる突起により形成される凹凸と人体（肌）との間に空気層ができ、蓄熱性が向上するのではないかと推定している。 Surprisingly, the heat storage property of the fabric is improved by including the inorganic fine particles in the resin layer. The reason for this has not been clarified yet, but due to the synergistic action of the infrared absorber contained in the resin layer and the inorganic fine particles, the inorganic fine particles are easily exposed (protrusions) to the resin layer, and are formed by the protrusions. It is estimated that an air layer is formed between the unevenness and the human body (skin), and the heat storage property is improved.
前記樹脂層を形成する樹脂の種類としては、ウレタン樹脂、アクリル樹脂、ポリエステル樹脂、シリコーン樹脂、塩化ビニル樹脂、ナイロン樹脂など公知のバインダー樹脂でよい。また、樹脂の基布に対する付着量は、樹脂固形分基準で基布に対して０．０１〜４０ｇ／ｍ２（より好ましくは５〜３０ｇ／ｍ２）の範囲内であることが好ましい。 As a kind of resin which forms the said resin layer, well-known binder resins, such as a urethane resin, an acrylic resin, a polyester resin, a silicone resin, a vinyl chloride resin, a nylon resin, may be sufficient. Further, the amount of adhesion to the base fabric of the resin is preferably 0.01~40g / m 2 (more preferably 5 to 30 g / m 2) to the base fabric with a resin solids in the range of.
ここで、優れた肌触りを得る上で、前記樹脂層の表面において、前記無機微粒子が露出していることが好ましい。また、かかる樹脂層は基布全面に付着していてもよいが、特開２００３−９６６６３号公報に記載されているように、格子状、飛島状、市松格子状、縞上など、基布の少なくとも片面（好ましくは片面のみ）上に部分的に付着していると、樹脂層が積層されていない個所の通気性が高まるので、ムレ感を低減することができ好ましい。その際、蓄熱性布帛の通気性としては０．２ｃｃ／ｃｍ２・ｓｅｃ以上（好ましくは０．２〜５．０ｃｃ／ｃｍ２・ｓｅｃ、特に好ましくは０．２〜３．０ｃｃ／ｃｍ２・ｓｅｃ）であることが好ましい。 Here, in order to obtain an excellent touch, the inorganic fine particles are preferably exposed on the surface of the resin layer. In addition, the resin layer may be attached to the entire surface of the base fabric, but as described in JP-A-2003-96663, the base fabric has a lattice shape, Tobishima shape, checkered lattice shape, stripes, and the like. If it is partially attached on at least one side (preferably only one side), the air permeability of the portion where the resin layer is not laminated is enhanced, so that it is possible to reduce the feeling of stuffiness. At that time, as the breathability of the heat storage fabric 0.2cc / cm 2 · sec or more (preferably 0.2~5.0cc / cm 2 · sec, particularly preferably 0.2~3.0cc / cm 2 · sec).

その際、かかる配合組成物は水系、溶剤系のいずれで構成してもよいが、加工工程の作業環境上水系の方が好ましい。溶剤としては、トルエン、イソプロピルアルコール、ジメチルホルムアミド、メチルエチルケトン、酢酸エチルなどが例示される。この配合組成物には、エポキシ系などの架橋剤を併用してもよい。さらに、基布本体に対する付着性を向上させる等の目的で適当な添加剤をさらに配合してもよい。 In this case, the blended composition may be composed of either an aqueous system or a solvent system, but an aqueous system is preferable in view of the working environment of the processing step. Examples of the solvent include toluene, isopropyl alcohol, dimethylformamide, methyl ethyl ketone, ethyl acetate and the like. This blended composition may be used in combination with an epoxy-based crosslinking agent. Furthermore, you may further mix | blend a suitable additive for the objective of improving the adhesiveness with respect to a base fabric main body.
