Mechanical fastening nets and methods of making the same

摘要

A method of making a mechanical fastening net. The method includes providing a net having strands of polymer and open areas between the strands of polymer and molding a portion of the polymer in the strands of the net into upstanding posts to form the mechanical fastening net. A mechanical fastening net that includes a polymeric backing, a plurality of openings in the polymeric backing, and upstanding posts on at least one of the first or second major surface of the polymeric backing is also disclosed. The polymeric backing has a range of thicknesses ranging from minimum to maximum thickness, and for at least a portion of the polymeric backing, the minimum thickness of the polymeric backing is where it abuts one of the openings.

1. A mechanical fastening net comprising:
a polymeric backing comprising first and second major surfaces, a plurality of openings in the polymeric backing extending between the first and second major surfaces, and upstanding posts on at least one of the first or second major surface of the polymeric backing, wherein for a portion of the polymeric backing between two adjacent openings not having upstanding posts abutting the two adjacent openings, the polymeric backing has a minimum thickness where it abuts one of the two adjacent openings that is smaller than a maximum thickness of the polymeric backing at a location between the two adjacent openings.
