Description
ここで不織布としての目付けは、特に限定はないがポリオレフィンを用いる場合には1〜1000g/m2とするのが一般的である。
ここで、親水性は、EDANA150 2−93に示される液通過速度の測定において10秒以内で液通過が認められたものを親水性を有するものとして評価した。
また、印刷を施す際に、印刷が不要な部分を加熱し、親水性を失わせることにより事により、より鮮明な印刷が施された成形体を簡便に得ることも出来る。
Claims (7)
- 疎水性の熱可塑性樹脂100質量部に対しポリエチレングリコールからなる親水性のブロックとポリメチレンからなる疎水性のブロックを有する共重合体0.01質量部以上を加熱溶融混合した組成物を成形してなる親水性の成形体の親水性が不要な部分を親水性を失う温度以上に加熱することを特徴とする親水性部と疎水性部を有する成形体の製造方法。
- 疎水性の熱可塑性樹脂がポリオレフィンである請求項1に記載の方法。
- 成形体が不織布である請求項1に記載の方法。
- 請求項1〜3のいずれかに記載の製造方法で得られる親水性部と疎水性部を有する成形体の加熱処理面側に印刷を施し、さらに印刷後、該成形体の疎水性部からインクを除去することを特徴とする成形体の製造方法。
- インクが水性のインクである請求項4に記載の方法。
- 疎水性の熱可塑性樹脂がポリオレフィンである請求項4に記載の方法。
- 成形体が不織布である請求項4に記載の方法。
