Description
歯ブラシ用毛の材質である樹脂の粉末として、ナイロン612(Dupont、Tynex)、ポリブチレンテレフタレート(PBT)(KOLON)及びポリケトン(HYOSUNG、M310U及びM310U類似グレード)それぞれを加熱して押出装置のノズルで成形押出し、それを冷却して熱風で乾燥して、それぞれの素材で直径0.18mmの歯ブラシ用毛を製作した。
歯ブラシ用毛を製作した後、一本の剛性を評価するため、歯ブラシ用毛が破断する力である引張強度を測定して、従来の歯ブラシ用毛素材であるナイロン612及びPBTと比較評価した。
また、ポリケトンの耐久性を確認するため、ポリケトン歯ブラシ用毛を歯ブラシのヘッドに植え付けて歯ブラシを製作し、ナイロン612とPBT歯ブラシ用毛を適用した歯ブラシとの弾力損失度を比べた。
毛の材質毎に歯ブラシ用毛の引張強度(Kgf)及び弾力損失度(%)を測定した結果を下記表1に示した。
ポリケトンのように剛性が高く、優れた耐磨耗特性を有する高分子として、フッ素系樹脂(PTFE、PVDF)、POM、PBT、PESなどがあるが、フッ素系樹脂の場合は溶融点が高くて歯ブラシ用毛を製作し難く、POMの場合は脆い特性のため歯ブラシ用毛としては適しない。PBTとPESは、ポリケトンのように強度が十分高くて優れた耐磨耗性を有する素材であるため、これら素材を用いて上述した製造例と同じ方法で直径0.18mmの歯ブラシ用毛を製作した。毛先は別途の微細毛加工を施さずに植え付けて歯ブラシを製作した。その後、製作した3種の素材の歯ブラシを用いて、専門パネリストによる歯茎刺激の程度に対するアンケート調査を通じてパネリスト評価を行った。
直径1.6mmの穴が32個形成された同じ歯ブラシのヘッドに、それぞれ直径5M(0.127mm)のナイロン歯ブラシ用毛とポリケトン歯ブラシ用毛を植え付けて実験用歯ブラシを製作した。これら歯ブラシをそれぞれ20~40代の女性20名と男性20名を対象に7日ずつ使用して比べるようにした。新しい歯ブラシを使用する前に、3日間の休止期を有し、休止期中には普段の習慣どおり歯を管理するようにした。
直径の小さい歯ブラシ用毛を適用した歯ブラシであるほど、歯間洗浄力が優れるが、直径の小さい歯ブラシ用毛、特に従来最も多く適用されるナイロン毛の場合、歯ブラシ用毛が切れ易く、弾力がなくて広がり易いという短所がある。
(1)引張強度
一本の歯ブラシ用毛が破断する力を評価するため、万能試験機(UTM)で歯ブラシ用毛一本を上/下端を1cmの間隔を置き把持した後、200mm/minの速度で上端を引っぱって切れるときの力を測定した。
ブラッシングの後に歯ブラシの毛先が広がる程度を評価するため、歯ブラシのブラッシング評価機に往復5,000回ブラッシングした後広がった幅を測定し、ブラッシング直後のポリケトン歯ブラシ用毛及びナイロン歯ブラシ用毛の様子をそれぞれ撮影して図2に示した。
歯ブラシ用毛の弾力(または、柔らかさ)を評価するため、掛かる力の測定が可能なワイヤに歯ブラシ用毛の1/3地点を掛けて力を測定した。
上記のように引張強度、弾力損失度及び弾力性を測定した結果を下記表4に示した。
