Abstract
A process is disclosed for forming a three-dimensional structure from a nonwoven web. The web is made of synthetic polymer filaments. The process comprises subjecting the web to a molding force at a temperature between the glass transition temperature and the melting temperature of the polymer. The nonwoven web is constructed so as to allow ample elongation of the constituent filaments. The web is preferentially bonded in selected areas. The filaments are only partially drawn during the spinning process, so as to preserve elongation potential. The three-dimensional structures made by the process can be shaped filters, for example for use in beverage capsules.
