Abstract
A structure for use in industrial fabrics such as paper machine clothing and engineered fabrics. The structure is a bicomponent extruded elastomeric netting or mesh having a high degree of both compressibility under an applied normal load and excellent recovery (resiliency or spring back) upon removal of that load.
Claims42
A fabric comprising a bicomponent extruded mesh including:
- a first layer of the parallel strands running in the machine direction;
- a second layer of the parallel strands on one side of the first layer, the second layer's strands running in the cross machine direction and comprising elastomeric strands;
- and
- a third layer of the parallel strands on the opposite side of the second layer as the first layer and running in the same direction as those of the first layer,
- wherein the first, second, and third layers are co-extruded together such that the strands in the first layer are positioned or aligned within the space between strands in the third layer, and
- one or more layers of a woven fabric, membrane, machine direction (MD) or cross machine direction (CD) yarn array, or spiral link fabric attached to a top and/or bottom surface of the extruded mesh.

A method for forming a bicomponent extruded mesh, the method comprising the steps of:
- extruding a first layer of the parallel strands in the machine direction;
- co-extruding a second layer of the parallel strands on one side of the first layer, the second layer's strands running in the cross machine direction and comprising elastomeric strands;
- and
- co-extruding a third layer of the parallel strands on the opposite side of the second layer as the first layer and running in the same direction as those of the first layer,
- wherein the first, second, and third layers are co-extruded together such that the strands in the first layer are positioned or aligned within the space between strands in the third layer.
