Title (EN) DISPOSABLE WEARABLE ARTICLE
(FR) ARTICLE VESTIMENTAIRE JETABLE
(JA) 使い捨て着用物品
Abstract:
(EN) [Problem] To provide a disposable wearable article that has a laminate stretch structure with excellent peel strength and flexibility. [Solution] This problem is solved by a disposable wearable article that includes a laminate stretch structure (20X) in which a thermoplastic resin elastic sheet (30) is disposed between a nonwoven first sheet layer (20A) and a nonwoven second sheet layer (20B) and in which the first sheet layer (20A) and the second sheet layer (20B) are joined at a plurality of interstitially-separated join parts (40) via through-holes (31) formed in the elastic sheet (30), the disposable wearable article being characterized in that at each join part (40) the first sheet layer (20A) and the elastic sheet (30) are melt-solidified, at least the layer of the second sheet layer (20B) forming a surface opposite the side with elastic sheet (30) is not melt-solidified, and the first sheet layer (20A) and the second sheet layer (20B) are joined at each join part (40) by means of a melt-solidified substance (m1) of the first sheet layer (20A) and a melt- solidified substance (m2) of the elastic sheet (30).
(FR) Le problème décrit par la présente invention est de proposer un article vestimentaire jetable qui présente une structure d'étirement stratifiée, caractérisée par une remarquable résistance au pelage et une très grande flexibilité. La solution selon l'invention consiste en un article vestimentaire jetable qui comprend une structure d'étirement stratifiée (20X) dans laquelle un voile élastique en résine thermoplastique (30) est disposé entre une première couche de voile non tissé (20A) et une seconde couche de voile non tissé (20B) et dans laquelle la première couche de voile (20A) et la seconde couche de voile (20B) sont reliées au niveau d'une pluralité de parties de jonction séparées par des interstices (40) se présentant sous la forme de trous traversants (31) formés dans le voile élastique (30), l'article vestimentaire jetable étant caractérisé en ce qu'au niveau de chaque partie de jonction (40), la première couche de voile (20A) et le voile élastique (30) sont fondus, puis solidifiés, au moins la couche correspondant à la seconde couche de voile (20B) formant une surface opposée au côté comportant le voile élastique (30) n'est pas fondue, ni solidifiée, et la première couche de voile (20A) et la seconde couche de voile (20B) sont reliées au niveau de chaque partie de jonction (40) au moyen d'une substance fondue, puis solidifiée (m1) formée de la première couche de voile (20A) et d'une substance fondue, puis solidifiée (m2) formée du voile élastique (30).
(JA) 【課題】剥離強度・柔軟性に優れる積層伸縮構造を備えた使い捨て着用物品を提供する。【解決手段】上記課題は、不織布からなる第1シート層(20A)と、不織布からなる第2シート層(20B)との間に、熱可塑性樹脂の弾性シート(30)が積層され、第1シート層(20A)及び第2シート層(20B)が、間隔を空けて配列された多数の接合部(40)で弾性シート(30)に形成された貫通孔(31)を通じて接合された、積層伸縮構造(20X)を備えており、接合部(40)では、第1シート層(20A)及び弾性シート(30)は溶融固化し、第2シート層(20B)における少なくとも弾性シート(30)側と反対側の面を形成する層は溶融固化しておらず、第1シート層(20A)及び第2シート層(20B)は、接合部(40)で、第1シート層(20A)の溶融固化物(m1)及び弾性シート(30)の溶融固化物(m2)を介して接合されている、ことを特徴とする使い捨て着用物品により解決される。
