Abstract:
(EN) [Problem] To improve, with excellent texture kept, the shape retention of protrusions and recesses formed by surface embossing, and thereby not only improve the touch and the feel of unevenness but also enhance the absorption performance. [Solution] A sanitary napkin (1) which has an absorber body (4) interposed between a liquid-permeable front sheet (3) and a back sheet (2) and which is provided with a hydrophilic second sheet (6) between the liquid-permeable front sheet (3) and the absorber body (4). The liquid-permeable front sheet (3) has a laminate structure comprising: a fine-fiber layer (3A) which constitutes the skin-contact surface layer and which is composed of fine fibers having a fineness of less than 2.0dtex; and a crimped fiber layer (3B) which is adjacently laminated on the non-skin-contact side of the fine-fiber layer (3A) and which is composed of crimped fibers having a fineness of 3.0 to 5.0dtex. The liquid -permeable front sheet (3) has many protuberances (7,7···) which are formed by embossing and which protrude on the skin side.
(FR) La présente invention a pour but d'améliorer, tout en conservant une excellente texture, la stabilité de forme de saillies et de renfoncements formés par bossage de la surface, et d'améliorer ainsi non seulement le toucher et la sensation d'inégalité, mais également l'efficacité d'absorption. Pour atteindre ce but, l'invention concerne une serviette hygiénique (1) qui comprend un corps d'absorbeur (4) interposé entre une feuille avant perméable aux liquides (3) et une feuille arrière (2), et qui est pourvue d'une seconde feuille hydrophile (6) entre la feuille avant perméable aux liquides (3) et le corps d'absorbeur (4). La feuille avant perméable aux liquides (3) présente une structure de stratifié comportant : une couche de fibres fines (3A) qui constitue la couche de surface de contact avec la peau et qui est composée de fibres fines ayant une finesse inférieure à 2,0 dtex ; une couche de fibres crêpées (3B) qui est stratifiée de façon adjacente sur le côté de non contact avec la peau de la couche de fibres fines (3A), et qui est composée de fibres crêpées ayant une finesse de 3,0 à 5,0 dtex. La feuille avant perméable aux liquides (3) présente de nombreuses saillies (7, 7...) qui sont formées par bossage et qui font saillie sur le côté de contact avec la peau.
(JA) 【課題】肌ざわりの良さを維持したまま、表面凹凸加工による凹凸形状を維持しやすくし、肌触り感や凹凸感を優れたものとするとともに、吸収性能を高める。【解決手段】透液性表面シート(3)と裏面シート(2)との間に吸収体(4)が介在されるとともに、前記透液性表面シート(3)と吸収体(4)との間に親水性のセカンドシート(6)が備えられた生理用ナプキン(1)である。前記透液性表面シート(3)は、肌当接面層を構成する繊度2.0dtex 未満の細繊維からなる細繊維層(3A)と、この細繊維層(3A)の非肌面側に隣接して積層される捲縮繊維からなる繊度3.0~5.0dtex の捲縮繊維層(3B)とを含む積層構造とされ、且つ肌側に突出する多数の隆起部(7、7…)からなる凹凸状のエンボス加工が施されている。
