Abstract
In some embodiments, a nonwoven fabric includes a first web that is at least partially formed of extruded strands which include an auto-adhesive material. The nonwoven fabric is adapted to be bonded to another item that includes a similar auto-adhesive material. In other embodiments, a method of forming a nonwoven fabric includes extruding a plurality of strands that are formed of an auto-adhesive material. The method further includes routing the plurality of strands toward a moving support, depositing the plurality of strands onto the moving support, and then stabilizing the plurality of strands to form a web. In other embodiments, a fastening system includes a nonwoven fabric that has a web which is formed of a plurality of extruded strands that include an auto-adhesive material. The fastening system further includes a foam layer that has a surface with a plurality of free-standing struts that include a similar auto-adhesive material.
