- the adhesive for example, general-purpose adhesives such as rubber-based adhesives, acrylic adhesives, hot-melt adhesives, and silicone-based adhesives can be used.
- rubber-based adhesives include natural rubber-based adhesives, styrene/butadiene rubber-based adhesives, recycled rubber-based adhesives, polyisobutylene/butylene rubber-based adhesives, polybutene-based adhesives, block copolymer-based adhesives, and the like. . These adhesives can be used alone or in combination.
- the mites trapping product 100 preferably attracts and traps mites that have invaded an area within a radius of 1 m.
- "attracted and captured” means not only the state in which the attracted mites are fixed to the surface of the adhesive 20, but also the state in which the attracted mites remain inside the mites-capturing product 100, particularly in the fiber structure 10. Including the state where it is set.
- the mites trapping product 100 can attract and trap mites approaching the mites trapping product 100 within 24 hours, depending on the mites breeding situation and installation location. Twenty-four hours is a short enough time to trap mites, making the mites trapping product 100 practical.

厚さ0.05mmのPET樹脂シートの両面にゴム系ホットメルト接着剤を塗布して粘着体を作製した。粘着体の両面に織物を積層して繊維構造体とし、3層からなる積層体を得た。繊維構造体に用いた織物は、ウール糸を糸密度が19~22本/10cmとなるように平織にした織物であり、厚みが0.67mm、目付が189g/m2であった。積層体をポリエチレン製ネット(通気性シート)からなる袋体に封入することで、5層からなる比較例7のダニ類捕獲製品を得た。ポリエチレン製ネットには、網目の間隔が1mm、厚みが0.03mm、目付が67g/m2であるものを用いた。ポリエチレン製ネットは、毛羽を有さず、ポリエチレン製ネット上に10cmの線分を設けた際に、線分に交差する繊維の数は、95~110本であった。
実施例1~16のダニ類捕獲製品、及び比較例1~7のダニ類捕獲製品について、3cm×3cmのサイズに切り出したものを試験片とし、直径4.5cmのガラス製シャーレ(高さ1.5cm)の中央に設置した。直径9cm(高さ2cm)のガラス製シャーレの中央に、先の直径4.5cmのシャーレを設置し、直径9cmのガラス製シャーレの内部に約10000匹のヤケヒョウヒダニを放ち、室温25℃、湿度80%の暗所条件下で静置した。24時間後に試験片の粘着体に固着されたダニを計数し捕獲数とした。試験は実施例1~16のダニ類捕獲製品、及び比較例1~7のダニ類捕獲製品の夫々について3回繰り返し、捕獲数の平均値を算出した。コントロールとして、実施例1のダニ類捕獲製品の作製に用いた粘着体のみを3cm×3cmのサイズに切り出して直径4.5cmのガラス製シャーレの中央に設置し、実施例及び比較例のダニ類捕獲製品と同様の試験をし、粘着体に固着されたダニの捕獲数を計数した。実施例1~16のダニ類捕獲製品、及び比較例1~7のダニ類捕獲製品による捕獲数を、コントロールにおける捕獲数により除した値を、捕獲比として算出した。
実施例1~16のダニ類捕獲製品、並びに比較例1~4、及び7のダニ類捕獲製品について、繊維構造体を構成する織物から糸を採取し、「JIS L 1095 一般紡績糸試験方法」のJIS法に準拠して伸び率(%)を測定した。

実施例17で用いた粘着体を、実施例17で用いたポリエチレン製ネットからなる袋体に封入し、比較例8の製品を得た。すなわち、比較例8の製品は、実施例17のダニ類捕獲製品に対して、動物性及び植物性の食品成分を含有する混練固化錠剤、及び繊維構造体を使用しないものである。
図5は、捕獲距離試験の試験方法を説明する図である。一般的な敷布団サイズ(100×200cm)の1/4の大きさとなる50cm×100cmの未使用のポリエステル製シーツXを木板の上に敷き固定した。シーツXの外周に当たる部分Wは木板に溝を掘り、ダニの逃亡や他のダニの混入を防ぐために水を注いだ。ここで、図5に示すように、シーツXに、角部A、角部B、及び短辺中央部Cを設定する。角部Bから角部Aまでの距離D1は約110cmであり、角部Bから短辺中央部Cまでの距離D2は約25cmである。シーツXの角部A、及びシーツXの短辺中央部Cに実施例17のダニ類捕獲製品Yを設置し、シーツXの角部Bにヤケヒョウヒダニ約1000匹を培地ともに放った。この木板を3個準備し、25℃、75%RHの暗所条件に設置し、24時間後、及び20日後にダニ類捕獲製品Yの粘着体に固着されたダニを計数した。比較例8の製品についても、同様の捕獲距離試験を行った。
