    • PROBLEM TO BE SOLVED: To provide an absorbent article unlikely to allow leakage of bodily fluid which has been discharged from a wearer.SOLUTION: This absorbent article 1 includes: a liquid permeable front surface sheet 20; a liquid impermeable rear surface sheet 30 provided at a position facing the front surface sheet 20; an absorber 40 provided between the front surface sheet 20 and the rear surface sheet 30; and a second sheet 50 provided between the front surface sheet 20 and the absorber 40. A plurality of recesses 70 extending from the front surface sheet 20 to the inside of the second sheet 50 are formed by compression heating in the thickness direction. The fibers of the front surface sheet 20 are thermo-plastically deformed in the recesses 70. The linear shape of the fibers of the front surface sheet 20 is maintained at the bottoms of the recesses 70. The front surface sheet 20 is joined to the second sheet using an adhesive agent, and the second sheet 50 includes air-laid nonwoven fabric containing pulp.
    • 要解决的问题:提供一种吸收制品,其不会容易从穿戴者排出的体液泄漏。 该吸收性物品1包括:透液性前表面片20; 设置在面向前表面片20的位置处的液体不可渗透的后表面片30; 设置在前表面片20和后表面片30之间的吸收体40; 以及设置在前表面片20和吸收体40之间的第二片50.通过在厚度方向上的压缩加热形成从前表面片20延伸到第二片50的内部的多个凹部70。 表面片20的纤维在凹部70中热塑性变形。前表面片20的纤维的直线形状保持在凹部70的底部。前表面片20与第二片 使用粘合剂的片材,第二片材50包括含有纸浆的气流成网无纺布。 版权所有(C)2013,JPO&INPIT

    • PROBLEM TO BE SOLVED: To obtain a sanitary napkin which absorbs menstrual blood quickly, shows little return of the menstrual blood to a surface of the skin side when it is pressed, and makes the color of the menstrual blood inconspicuous at the surface of the skin side since the menstrual blood is absorbed in a liquid absorbing layer.
      SOLUTION: A surface sheet 5 is formed by a resin film having many liquid permeating holes 5a and barrier layers 11 which are formed by resin films having many liquid permeating holes 11a exist between the surface sheet 5 and the liquid absorbing layer 7. The barrier layers 11 are formed in belt shapes and liquid passing regions 12 are formed between the adjacent barrier layers 11. The menstrual blood which passes through the liquid permeating holes 5a of the surface sheet 5 is absorbed by the liquid absorbing layer 7 through the liquid passing regions 12. The barrier layers 11 prevent the return of the liquid and function to cover the color of the menstrual blood.

    • 要解决的问题:为了获得快速吸收经血的卫生巾,当按压时,经血几乎不返回到皮肤表面,并使月经的颜色在表面不显眼 因为经血被吸收在液体吸收层中。 解决方案:表面片5由具有许多液体渗透孔5a和阻挡层11的树脂膜形成,阻挡层11由表面片5和液体吸收层7之间存在许多液体渗透孔11a的树脂膜形成。 阻挡层11形成为带状,并且在相邻的阻挡层11之间形成有液体通过区域12.穿过表面片材5的液体渗透孔5a的经血被液体吸收层7通过液体 阻挡层11防止液体的返回并且起到覆盖经血的颜色的作用。 版权所有(C)2006,JPO&NCIPI
