Abstract
A method of making a mechanical fastening strip and a reticulated mechanical fastening strip are disclosed. The method includes providing a backing having upstanding posts; providing interrupted slits through the backing, the interrupted slits being interrupted by at least one intact bridging region; spreading the slit backing to provide multiple strands separated from each other between at least some of the bridging regions to provide at least one opening; and fixing the multiple strands of the backing in a spread configuration. The reticulated mechanical fastening strip includes multiple strands of a backing attached to each other at bridging regions in the backing and separated from each other between the bridging regions to provide openings. Upstanding posts on each of the multiple strands have bases attached to the backing, and each of the multiple strands has a width that is greater than that of the bases of its attached upstanding posts.
