Abstract
【解決手段】ウェスト開口部1の少なくとも一部を形成する腹側ウェスト部10a及び背側ウェスト部10bと、腹側本体部20a及び背側本体部20b並びにレッグ開口部2a、2bの少なくとも一部を形成する股部20cからなる本体部20とを備えており、股部20cを除くおむつ101のいずれかの部位が伸張性の繊維集合体7と間隔を置いて複数配置された、エラストマー成形体6とを含む積層体5で構成されており、エラストマー成形体6は、伸張性の繊維集合体7に接合している領域と、伸張性の繊維集合体7から離間している領域とを有する、おむつ101。
【選択図】 図4
Description
以下、図9を参照して、2層構造の伸縮性積層体5の製造方法の一例について説明する。まず、メルトブロー法によりシート状の繊維集合体7が製造される。製造されたシート状の繊維集合体7は、図9の矢印に示すように、波状の凹凸パターンを有する成形ロール300,301の間に送り出され、谷部7a及び山部7bを有する波状の繊維集合体7に成形される。使用する成形ロール300,301を変えることにより、繊維集合体7の形状(谷部7a及び山部7bの形状)を任意に変更することができる。波状に成形された繊維集合体7は、成形ロール301の回転により、成形ロール301とチルロール302の間に送られる。
以下、図13〜15を参照し、第1実施形態、第4実施形態及び第7実施形態に係るおむつの製造方法について説明する。
繊維集合体(波状):サーモプラスチックポリウレタン(TPU)からなる芯材をポリプロピレン(PP)からなる鞘材で覆った鞘芯型の複合繊維により構成された繊維集合体を用意した。繊維断面における鞘材と芯材との面積比率は、10:90である。
繊維集合体の坪量は30g/m2とした。繊維集合体のピッチ(幅方向における1cm当たりの山部7bの数)が3.93cm−1、谷部7aの下端と山部7bの上端との高さの差が1mm、山部7bの幅が1mmの波状となるように繊維集合体を成形した。
繊維集合体(フラット):波状の繊維集合体と同じ鞘芯型の複合繊維によりフラットに構成した。繊維集合体の坪量は15g/m2とした。
エラストマー成形体:Tダイ1軸溶融押出し機とチルロールとからなるフィルム製造装置(田辺プラスチック機械工業株式会社製、型番:VS30)を用い、SIS共重合体からなる芯材をポリプロピレン(PP)からなる鞘材で覆った、直径0.5mmの円形状断面を有するストランド状のエラストマー成形体を作製した。断面における鞘材と芯材との面積比率は、2:98である。
ストランド状のエラストマー成形体を、幅方向で5本/cmとなるように並べた。エラストマー成形体の坪量は50g/m2とした。
エラストマー成形体に対する繊維集合体の接合は、200℃以上、300℃以下の温度のラミネート(熱融着)によって行い、伸張性積層体を作製した。
得られた伸張性積層体を幅25mm、長さ80mmの長方形状に形成して、ひずみ試験を行った。ひずみ試験では、伸張性積層体を25mmのチャック間距離で挟み込み、引張速度を300mm/minとして、伸張性積層体の伸びが100%となるまで引張した後に戻すサイクルを二回行った。
図16は、ひずみ試験において伸張性積層体に生じる応力と伸びとの関係を示す図である。図16に示すように、第1の荷重工程及び第1の戻り工程を1回目のサイクル、第2の荷重工程及び第2の戻り工程を2回目のサイクルとして、2回目のサイクル後のひずみ(第2のひずみ)の計測を行った。
得られた伸張性積層体を幅25mm、長さ80mmの長方形状に形成して、接合強度(デラミネーション)試験を行った。接合強度試験では、3層の伸張性積層体の端部を割いて繊維集合体(波状)と繊維集合体(フラット)とエラストマー成形体とに分け、分かれた繊維集合体(波状)と繊維集合体(フラット)のそれぞれを別々のチャックで挟み込んだ。チャック間距離は25mmとした。引張速度を500mm/minとして伸張性積層体の接合強度(伸張性積層体を剥がすために必要な荷重)の平均値を測定した。
