Abstract
A method of manufacturing a non-woven fabric which is bulky caused by fiber-raised construction on the surface of a non-woven fabric includes adhering a non-woven web with its surface layer portion containing an easy-to-heat-melt component showing a property to be adhesive as heated to a smooth surface heated at the temperature for the easy-to-heat-melt component to show a property to be adhesive with the surface layer portion in contact with the smooth surface, and then raising the fibers of the non-woven web by peeling the non-woven fabric like web off the smooth surface so that a fiber-raised bulky state is generated, whereby a fiber-raised bulky structure is formed on the surface of the non-woven fabric.
