Title:
不織布状ウェブの嵩高加工方法およびそれにより得られる嵩高性不織布
Document Type and Number:
Japanese Patent JP4224890
Kind Code:
B2
Abstract:
A method of manufacturing a bulky, non-woven fabric having a fiber-raised construction on the surface of the non-woven fabric is disclosed. The method includes adhering a non-woven web, with a surface layer portion containing an easy-to-heat-melt component which becomes adhesive when heated, to a smooth surface. The smooth surface is heated at the temperature for the easy-to-heat-melt component of the surface layer portion to become adhesive and to bond to the smooth surface, and subsequent raising of the fibers of the non-woven web is achieved by peeling the non-woven fabric like web off the smooth surface, so that a fiber-raised bulky state is generated on the surface of the non-woven fabric. The smooth surface can be in the form of a heated roll, and the easy-to-heat-melt component can be a hot melt adhesive polymer.
