Abstract

L'invention concerne une structure améliorant les performances d'un gousset, laquelle comporte au moins deux surfaces, et son procédé de fabrication. L'une desdites au moins deux surfaces est une surface avant et l'autre desdites au moins deux surfaces est une surface arrière. La surface avant est tournée vers un utilisateur et une surface arrière est située à l'opposé de la surface avant. La surface avant est une surface évacuant l'humidité par effet de mèche et la surface arrière est une surface absorbant l'humidité. La structure améliorant les performances d'un gousset est apte à transporter l'humidité dans un seul sens, de la surface avant à la surface arrière, et elle est conçue pour contenir un grand volume de fluides corporels dans une zone de surface minimale.
