摘要:
PROBLEM TO BE SOLVED: To provide a laminated nonwoven fabric which has a good skin touch and suppresses an amount of returned fluid, and a method for producing the laminated nonwoven fabric.SOLUTION: There is provided a laminated nonwoven fabric 20 of a laminated structure comprising an upper layer fiber layer 20A and a lower layer fiber layer 20B. The laminated nonwoven fabric includes: protrusions 21 that protrudes to a first face side Z1 when the laminated nonwoven fabric 20 is planarly viewed and that has an internal space 23 to a second face side Z2 which is opposite to the first face side Z1 and recesses 22 recessing to the second face side Z2. A plurality of the protrusions 21 and the recesses 22 are alternately and continuously disposed through wall parts 25 in different intersectional directions, respectively, when the laminated nonwoven fabric 20 is planarly viewed. The first face side Z1 is the upper layer fiber layer 20A side and the second face side Z2 is the lower layer fiber layer 20B side. A water-absorbent fiber 26 is arranged at least in the lower layer fiber layer 20B.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】肌触りが良く、液戻り量が少ない積層不織布およびその製造方法を提供することである。【解決手段】上層繊維層20Aと下層繊維層20Bを有する積層構造の積層不織布20であって、該積層不織布20を平面視した側の第1面側Z1に突出し該第1面側Z1とは反対の第2面側Z2に内部空間23を有する凸部21と、前記第2面側Z2に凹んだ凹部22とを有し、前記凸部21と前記凹部22は、該積層不織布20の平面視交差する異なる方向のそれぞれに、壁部25を介して交互に連続して複数が配され、前記第1面側Z1が上層繊維層20A側、前記第2面側Z2が下層繊維層20B側であり、少なくとも前記下層繊維層20Bに吸水性繊維26を配した積層不織布20である。【選択図】図1
