Industrial fabric comprising an extruded mesh and method of making thereof

摘要

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.

主权项

1. A bicomponent mesh having layers of parallel strands formed by extrusion, comprising:
a first layer of the parallel strands running in a first direction; a second layer of parallel strands on one side of the first layer, the second layer's strands running in a second 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 at substantially the same time such that the strands in the first layer are positioned or aligned within the space between strands in the third layer, wherein the first, second, and third layers form a structure having a desired thickness, wherein under a compressive load the second layer stretches to enable the strands of the first and third layers to nest between each other in substantially the same plane, and wherein upon release of the compressive load elasticity of the second layer causes the first and third layers to spring back returning the structure to substantially the desired thickness.
