Description
本発明は、衣類、寝具、装身具等の繊維製品の形成に用いた場合に使用者に良好な接触冷感を提供可能な繊維製品に関するものである。
The present invention relates to textile products that can provide users with a good cooling sensation when used to form textile products such as clothing, bedding, and accessories.
近年、夏季用の肌着や寝具カバー等として、使用時にヒヤリとした涼しげな感触を提供可能な接触冷感に優れた繊維（接触冷感性繊維）を用いたものが研究されている。そして、そのような接触冷感性繊維としては、特許文献１の如く、吸水性ポリマーを内包させた多孔質無機粉末粒子（結晶性多孔質アルミノケイ酸塩、多孔質シリカ、多孔質アルミナ等）を把持させた合成樹脂繊維が開発されている。かかる合成樹脂繊維によれば、吸水性ポリマーに予め含有されている水分が蒸発するときの気化熱を使用者の体から奪う作用によって、使用者に接触冷感を与えることができる。
In recent years, research has been conducted on underwear, bedding covers, etc. that use fibers with excellent coolness to the touch (coldness to the touch) that can provide a cool feeling when used. And, as such a contact cooling fiber, porous inorganic powder particles (crystalline porous aluminosilicate, porous silica, porous alumina, etc.) containing a water-absorbing polymer are held as in Patent Document 1. Synthetic resin fibers have been developed. Such synthetic resin fibers can provide the user with a cool contact sensation due to the action of removing the heat of vaporization from the user's body when the moisture previously contained in the water-absorbent polymer evaporates.
しかしながら、特許文献１の合成樹脂繊維は、肌着や寝具カバーとして利用した場合には、ある程度の接触冷感を発現させることができるものの、十分な接触冷感を発現させるためには大量の多孔質無機粉末粒子を含有させる必要があるため、原料樹脂本来の特性が損なわれ、必ずしも良好な風合いや肌触りを提供することができなかった。また、特許文献１の合成樹脂繊維を用いた肌着や寝具カバーは、長期間に亘って繰り返して使用すると、どうしても多孔質無機粉末粒子が合成樹脂繊維から剥がれてしまうため、良好な接触冷感を発現させることができなくなる、という不具合もあった。
However, when the synthetic resin fiber of Patent Document 1 is used as an underwear or bedding cover, it is possible to express a certain degree of coolness to the touch. Since it is necessary to contain inorganic powder particles, the original properties of the raw material resin are impaired, and it is not always possible to provide good texture and touch. In addition, the underwear and bedding cover using the synthetic resin fiber of Patent Document 1, when repeatedly used over a long period of time, will inevitably come off the porous inorganic powder particles from the synthetic resin fiber, so that a good cool contact feeling is obtained. There was also a problem that it could not be expressed.
本発明の目的は、上記特許文献１の如き従来の接触冷感タイプの繊維製品の有する問題点を解消し、衣類、寝具、装身具等の繊維製品の形成に用いた場合に使用者に良好な接触冷感（あるいは接触涼感）を提供可能であり、その良好な接触冷感を長期間に亘って発現させ続けることが可能である上、安価かつ容易に製造することができる繊維製品を提供することにある。

Furthermore, when the particle size (average value) of the silver ion-containing inorganic compound added to the polyester is adjusted to 0.1 to 100 μm, the dispersibility of the silver ion-containing inorganic compound in the polyester becomes good, and a small amount of addition is achieved. It is preferable because it is possible to effectively enhance the cool contact feeling of the textile product. The particle size of the silver ion-containing inorganic compound is more preferably 0.3 to 30 μm, particularly preferably 0.5 to 10 μm.
