    • PROBLEM TO BE SOLVED: To provide a nonwoven fabric sheet for an absorbent article such as a disposable diaper that provides a small diffusion range for a high viscosity excrement liquid and can reduce its reattachment on a skin.SOLUTION: A nonwoven fabric sheet of the invention is provided with: a longitudinal direction, a lateral direction and a thickness direction crossing perpendicular to each other; a surface and a rear face, which is the opposite face of the surface, in the thickness direction; ridge parts and groove parts formed such that they extend in parallel to one another in the longitudinal direction and repeat ups and downs in the lateral direction; a bottom face that contacts a horizontal plane when placing the nonwoven fabric sheet on the horizontal plane with the rear face, the opposite face of the surface contacting the skin of a wearer, downwards. On the rear face of the groove parts, relatively high sites from the bottom face and low sites corresponding to the bottom face are alternately arranged along the longitudinal direction. Openings are formed at least at the relatively high sites from the bottom and space is provided in a lower part of the openings.
    • 要解决的问题:提供一种用于吸收制品例如一次性尿布的非织造织物片,其提供用于高粘度排泄液的小扩散范围,并且可以减少其对皮肤的再附着。 解决方案:本发明的无纺织物片具有:彼此垂直交叉的纵向,横向和厚度方向; 表面和后表面,其在所述厚度方向上是所述表面的相对面; 脊部分和凹槽部分形成为使得它们在纵向方向上彼此平行地延伸并且在横向方向上重复上下颠倒; 将无纺布片与背面相对的水平面与接触皮肤的相反面向下方接触水平面的底面。 在凹槽部分的后表面上,从底面相对较高的位置和与底面对应的低位置沿纵向方向交替布置。 开口至少在底部的相对高的位置处形成,并且在开口的下部设置空间。 版权所有(C)2012,JPO&INPIT
