Beschreibung
Zusammenfassung:	A method of making an increased pile density composite elastic material including the steps of applying a tensioning force to elongate at least one elastic sheet; attaching fibrous materials to the elastic sheet while the elastic sheet is maintained in an elongated condition so that the fibrous materials protrude from the elastic sheet to form a pile; and releasing the tensioning force so the attached fibrous materials are positioned closer together by the recovery of the elastic sheet. The fibrous materials may be attached to the elastic sheet by being inserted into the elastic sheet or by being adhered onto the elastic sheet. Also disclosed is an increased pile density composite elastic material.
