本発明の実施例は、当該技術分野における平均的知識を有した者に本発明をより完全に説明するために提供するものである。
本発明は、おむつ製作工程のうち、スパンデックス繊維とポリプロピレン不織布またはポリエチレンフィルムとのホットメルト接着剤による接着力向上を目的とする。
本発明によれば、この際に適用されるエチレンビニルアセテート単量体、重合物及びその誘導体、または炭素が9つのハイドロカーボン系レジン単量体、重合物及びその誘導体、または炭素が5つのハイドロカーボン系レジン単量体、重合物及びその誘導体、またはC5/C9ハイドロカーボン系レジン単量体、共重合体及びその誘導体の粘着増進剤の含量がもしも0.1重量%未満の場合には、望まれる接着特性の向上効果が確認できなくなり、逆に30重量%を超過して投入する場合には原糸生産後、スパンデックス原糸の要求物性を確保できないという問題がある。
以下の本発明の実施例を通じてより詳しく説明するが、本発明は単に以下の実施例によって限定されるものではない。
ジフェニルメタン‐4,4′‐ジイソシアネート601.1gとポリテトラメチレンエテルグリコール(分子量1800)2664.5gを、窒素ガス気流中で90℃、95分間攪拌しながら反応させ、両末端にイソシアネートを有するポリウレタンプレポリマーを製造した。
次いで、エチレンジアミン43.3gと1,2‐プロフィールジアミン13.4g、ジエチルアミン5.7gをジメチルアセテートアミド829gに溶解して9℃以下で前記プレポリマー溶液に添加してポリウレタン溶液を得た。この重合物の固形分対比添加剤として酸化防止剤であるトリエチレングリコール‐ビス‐3‐(3‐ターシャリ‐ブチル‐4‐ヒドロキシ‐5‐メチルフェニル)プロピオネートを1重量%、耐光剤として二酸化チタン2重量%を投入して紡糸原液を得た。さらに粘着増進剤のエチレンビニルアセテート重合物を0.5重量%投入して紡糸原液を用意した。
紡糸原液中に粘着増進剤としてエチレンビニルアセテート重合物を3重量%投入することを除いては、前記実施例1と同様の方法でスパンデックス繊維を製造した。

紡糸原液中に粘着増進剤として炭素が5つのハイドロカーボン系レジン重合物を0.5重量%投入することを除いては、前記実施例1と同様の方法でスパンデックス繊維を製造した。
紡糸原液中に粘着増進剤としてC5/C9ハイドロカーボン系レジン共重合体を0.5%重量%投入することを除いては、前記実施例1と同様の方法でスパンデックス繊維を製造した。
紡糸原液中に粘着増進剤としてエチレンビニルアセテート重合物を33重量%投入したことを除いては、前記実施例1と同様の方法でスパンデックス繊維を製造した。
紡糸原液中に粘着増進剤として炭素が9つのハイドロカーボン系レジン重合物を33重量%投入することを除いては、前記実施例1と同様の方法でスパンデックス繊維を製造した。

<接着特性(Creep性)評価>
実施例及び比較例で収得されたスパンデックス繊維の接着特性を次のように評価した。スパンデックス繊維を用いておむつ製作後、当該サンプルを用いて以下のように評価した。
(1)スパンデックス繊維が投入された接着物部分をおむつの長さにまで最大伸長して横30cm、縦50cmのプラスチック板に固定させる。
(2)中央部を基準として両側左、右100mm(計200mm)部分を油性ペンを使用して表示する。
(3)表示された部分を鋭い刃で切ってスパンデックスが抜け出た程度を物差しを使用して測定する。
上記実施例1〜6及び比較例1〜7においてスパンデックス繊維の接着力を評価した結果を次表1に表示した。
<解糸張力評価>
実施例及び比較例で収得されたスパンデックス繊維は、粘着力の他に解糸特性の均一化した程度を確認するために次のように評価した。
この評価装置に用いられた張力測定装置は、ROTHSCHILD社の電子張力計(Electronic tension meter)を用いて測定した。最大(Max)値、最小(Min)値、平均(Ave)値,偏差(Dev.)値を次表2に表した。
<原糸の強度及び伸度>
自動強伸度測定装置(MEL機、Textechno社)を用いて試料長さ10cm、引張強度100cm/minにして測定した。この場合、破断時の強度と伸度値を測定した。
