PROBLEM TO BE SOLVED: To provide a nonwoven fabric that is excellent in wiping-off performance so that high collection efficiency is attained even when a capture object is viscose.SOLUTION: The nonwoven fabric comprises a cellulosic staple fiber and an acrylic staple fiber having a modified cross-section as constituent fibers, and the constituent fibers are three-dimensionally and integrally entangled with each other. The acrylic staple fiber has a cross section of a rectangular shape. At specific positions in a long axis direction of the rectangular shape, the acrylic staple fiber has arc-shaped projecting portions projecting to a short axis direction respectively. The height of each of the projecting portions is in the range of 0.5-1.5 times of the length of the short axis. The ratio of the short axis to the long axis of the rectangular shape is in the range of 1:10-1:15.COPYRIGHT: (C)2015,JPO&INPIT【課題】 捕捉物が粘性状のものであっても、高い捕集率となる拭き取り性能に優れた不織布を提供する。【解決手段】 セルロース系短繊維と、異型断面を有するアクリル短繊維とを構成繊維とし、構成繊維同士が三次元的に交絡一体化してなる不織布であり、アクリル短繊維は、その断面形状が短冊形であって、かつ、短冊形の長軸方向の特定の位置において、短軸方向にそれぞれ突出してなる円弧状の突出部を有し、該突出部のそれぞれの突出高さが短軸の長さの0.5~1.5倍の範囲にあり、短冊形における短軸と長軸との比が1:10~1:15の範囲であることを特徴とする不織布。【選択図】 図1
