    • The invention provides a nonwoven fabric that minimizes the condition of rewet-back in which fluid absorbed into an absorbent body exudes out to the front side, as well as a method for producing it. The nonwoven fabric 1 of the invention has a mutually perpendicular MD direction, CD direction and thickness direction, and has in the thickness direction a front side and a back side on the side opposite it, having on the front side heights 2 and recesses 13a formed so as to extend in an alternating fashion parallel to each other in the MD direction, forming repeating corrugations in the CD direction, and on the back side a back side section 3 formed across the entire side, the heights 2 being composed of height tips 21 located at the tips 2a of the heights 2 and neck sections 22 connecting the height tips 21 with the back side section 3, the cross-sectional widths of the neck sections 22 being narrower than the height tips 21 in a cross-section of the heights 2 in the CD direction, and having spaces between the recesses 13a formed by the two neck sections 22 supporting each of the adjacent height tips 21, and the back side section 3.
    • 本发明提供一种非织造织物,其使被吸收到吸收体中的流体向后流出的再润湿状态最小化,以及其制造方法。 本发明的无纺布1具有相互垂直的MD方向,CD方向和厚度方向,并且在厚度方向上具有在其相对侧的前侧和后侧,在前侧高度2和形成的凹部13a 以沿MD方向彼此平行的交替方式延伸,在CD方向上形成重复的波纹,并且在背面上形成横跨整个侧面的后侧部3,高度2由高度尖端21 位于高度2的尖端2a和连接高度尖端21与后侧部分3的颈部22处,颈部22的横截面宽度比高度尖端21的横截面高 2在CD方向上,并且在由支撑每个相邻高度尖端21的两个颈部22形成的凹部13a和后侧部3之间具有间隔。
