Abstract:
1. A sound absorbing material comprising: a nonwoven fibrous acoustic insulation material comprising a thermally bonded vertically lapped fibrous web; a flow resistive nonwoven facing, wherein the flow resistive nonwoven facing is bonded to the nonwoven fibrous acoustic insulation material and base surface mass of from about 20 to about 150 g/m a tape material adhered to the nonwoven fibrous acoustic insulation material on an opposite side to the flow resistive nonwoven facing, wherein the tape material comprises: a thin flexible substrate; a pressure sensitive adhesive (PSA) substance carried on a single side of the substrate, the PSA substance being provided in an intermittent pattern along a length of the substrate; and a mesh carried on the single side, wherein the mesh is open to expose the PSA substance for adhesion; wherein the PSA substance adheres the tape material to the nonwoven fibrous acoustic insulation material, and the thin flexible substrate is removable to reveal the PSA substance during use of the material.
