NONWOVEN FABRIC AND PROCESS FOR PRODUCING THE SAME |
摘要 |
The present invention aims to provide liquid-pervious nonwoven fabric allowing body fluids to be spot-permeated. A nonwoven fabric includes core-sheath type composite fiber of 100 to 30% by weight wherein a core component comprises high fusion point resin and a sheath component comprises a low fusion point resin. In a cut surface of the nonwoven fabric extending in parallel to a first direction, the composite fibers extend in the first direction with repetitive curvatures in a thickness direction of the nonwoven fabric. In a cut surface of the nonwoven fabric extending in a second direction, the composite fibers 2 extend in the thickness direction TD at an average fiber angle of 75° or less. The individual composite fibers intersect one another and fused together at respective intersection points by fusion of the low fusion point resin forming the sheath component. |
