Description
ポリブチレンテレフタレート及びポリトリメチレンテレフタレートを表1に示す配合比でブレンドしたそれぞれの樹脂を溶融紡糸して直径0.18mmの合成樹脂製モノフィラメントを得た。このモノフィラメントを中央部で折り曲げてブラシ毛として植毛台の植毛穴に10mmの長さで植設して歯ブラシの植毛部を構成し、下記の方法によりブラシ毛の破断および耐久性を調べた。
歯ブラシを37℃の温水に浸漬し、荷重1kgをかけて、1万回往復運動させた後、顕微鏡観察により、破断の有無を確認し、以下の基準で評価した。
○:数本の毛が屈曲
△:全体にわたり毛が破断
×:全体にわたり毛束が破断
歯ブラシを37℃の温水に浸漬し、荷重500gをかけて、1万回往復運動させた後のブラシ毛の拡がりを、(A)初期状態の歯ブラシ短軸方向の植毛部幅(植毛されているブラシ毛の先端における幅)と、(B)1万回往復運動後の毛の開いた状態の歯ブラシ短軸方向の植毛部幅とを測定し、下式により算定した耐久性指標(指数が低いほど耐久性に優れる。)をもとに、以下の基準で評価した。
耐久性指標(%)=[(B)/(A)]×100
◎:100−150%
○:150−200%
△:200−250%
