    • PROBLEM TO BE SOLVED: To provide a nonwoven fabric base material capable of efficiently wiping off granular solid dirt and peeled contamination and also sufficiently absorbing liquid contamination.SOLUTION: A nonwoven fabric base material 1 is structured so that ridges 2 and grooves 3 are alternately formed at mutually corresponding positions on both surfaces 1a, 1b and open holes 4 are formed in the grooves 3. The ridges 2 and the grooves 3 extend in parallel to one side of the nonwoven base material 1. Each of the grooves 3 is provided with open hole parts 3h with open holes 4, and non-open hole parts 3n without open holes 4 alternately. An arrangement pattern of the open hole parts 3h and the non-open hole parts 3n which are included in a groove 3a is different from an arrangement pattern of the open hole parts 3h and the non-open hole parts 3n which are included in a groove 3b adjacent thereto. The nonwoven fabric base material 1, in overall plan view, includes open hole areas 11 composed of the open hole parts 3h of the plurality of the grooves 3, and non-open hole areas 12 composed of the non-open hole parts 3n of the grooves 3. The open hole areas 11 and the non-open hole areas 12 are arranged in a predetermined pattern.
    • 要解决的问题:提供能够有效地擦去颗粒状固体污物和剥离污染物并且充分吸收液体污染的无纺布基材。解决方案:无纺织物基材1被构造成使得脊2和沟槽3交替形成 在凹槽3中形成两个表面1a,1b和开孔4上相互对应的位置。脊2和凹槽3平行于非织造基底材料1的一侧延伸。每个凹槽3设置有开口 具有开孔4的孔部3h和交替地没有开孔4的非开孔部3n。 包括在槽3a中的开孔部3h和非开孔部3n的布置图案与包括在槽3a中的开孔部3h和非开孔部3n的布置图案不同 3b。 无纺布基材1在整个平面图中包括由多个槽3的开孔部3h构成的露出孔区域11和由非开口部3n构成的非开孔区域12 开孔区域11和非开放孔区域12以预定图案布置。
