Description

本発明は、竹炭を含有するポリエステル綿を含む光発熱性の混紡糸、及びそれを用いた発熱性布帛に関する。 The present invention relates to a light-exothermic blended yarn containing polyester cotton containing bamboo charcoal, and an exothermic fabric using the same.

従来、衣服等の繊維製品の保温性を高める方法としては、生地を厚くする、生地の織目や網目を密にする等の方法で生地の断熱性を高め、身体等の内部の熱を逃さないようにする方法が一般的であった。また、中空繊維等の中空部分に空気の層を形成させることにより、保温性を高めた繊維製品も開発されている。これらの方法は、いずれも繊維製品で覆われた身体等のそれ自体の熱が、外部に逃げるのを防ぐことによる保温効果を利用するものであり、積極的な発熱効果は期待できない。 Conventionally, as a method of improving the heat retention of textile products such as clothes, the heat insulation of the fabric is increased by increasing the fabric thickness, the fabric texture and mesh are increased, and the heat inside the body is released. It was common to avoid it. In addition, fiber products having improved heat retention by forming an air layer in hollow portions such as hollow fibers have been developed. All of these methods use the heat retention effect by preventing the heat of the body or the like covered with the textile product from escaping to the outside, and a positive heat generation effect cannot be expected.

これに対して、太陽光を吸収しこれを熱に変換して衣服内部に放散させることで、発熱及び蓄熱効果を得ようとする試みもなされている。例えば、赤外線吸収剤を繊維製品に分散あるいは固着させて、赤外線領域の光を選択的に吸収し、内部に蓄熱する効果を有する繊維製品を得る方法が提案されている(例えば、特許文献1〜4参照)。

On the other hand, an attempt has been made to obtain heat generation and heat storage effects by absorbing sunlight, converting it into heat, and dissipating it into the clothes. For example, a method has been proposed in which an infrared absorbent is dispersed or fixed to a fiber product to selectively absorb light in the infrared region and obtain a fiber product having an effect of storing heat therein (for example, Patent Documents 1 to 3). 4).

また、発熱及び蓄熱効果を有する繊維製品を得るために、繊維の吸放湿性を利用したものも提案されている(例えば、特許文献5〜7参照)。特許文献5には、アクリレート系吸放湿発熱性繊維とポリエステル繊維の混紡糸が、特許文献6には、羊毛等の動物性繊維、ポリエステル等の疎水性合成繊維、及びアクリル系の吸放湿性発熱性繊維からなる混紡糸が開示されている。しかしながら、衣服として使用される繊維製品は、発熱性だけではなく風合い、吸湿性、適度の軽さ等の要件も要求される場合があり、従来提案されたものは、必ずしも全ての条件を満足するものではなかった。

Moreover, in order to obtain the fiber product which has a heat_generation | fever and a thermal storage effect, what utilized the moisture absorption / release property of the fiber is proposed (for example, refer patent documents 5-7). Patent Document 5 discloses blended yarns of acrylate-based moisture-absorbing / releasing exothermic fibers and polyester fibers, and Patent Document 6 discloses animal fibers such as wool, hydrophobic synthetic fibers such as polyester, and acrylic moisture-absorbing / releasing properties. A blended yarn composed of exothermic fibers is disclosed. However, textile products used as clothing may be required not only for exothermic properties but also for texture, moisture absorption, moderate lightness, etc., and conventionally proposed products do not necessarily satisfy all conditions. It was not a thing.

前記紡績糸を用いて、目付が245g/mの針抜きスムースの生地を製作した。かくして得られた編地は、表1(レフランプ照射試験)と表2(サーモグラフィー試験)に示したような性能を有していた。なお、比較品として、レーヨン綿40重量%とアクリル綿60重量%の混紡糸から得られた同組織の編地を用いた。竹炭を含有する本発明の編地は、太陽の光を素早く熱に変え、繊維内の温度を上昇させることが分かる。 Using the spun yarn, a needle-drawn smooth fabric having a basis weight of 245 g / m 2 was produced. The knitted fabric thus obtained had the performances shown in Table 1 (Refrump Irradiation Test) and Table 2 (Thermography Test). As a comparative product, a knitted fabric having the same structure obtained from a blended yarn of 40% by weight of rayon cotton and 60% by weight of acrylic cotton was used. It can be seen that the knitted fabric of the present invention containing bamboo charcoal quickly converts sunlight into heat and raises the temperature in the fiber.
