Abstract
A structure for use in industrial fabrics such as paper machine clothing and engineered fabrics is disclosed. The structure includes axially and radially elastic hollow members, and relatively inelastic yarns in various patterns. The structure has a high degree of both compressibility under an applied normal load and excellent recovery (resiliency or spring back) upon removal of that load.
Claims11
A compressible resilient industrial fabric, wherein the fabric includes a structure having an original thickness, the structure comprising:
- a laminated structure further comprising;
- a plurality of substantially parallel cross-machine direction (CD) yarns;
- a plurality of substantially parallel machine direction (MD) yarns;
- and
- a plurality of substantially parallel hollow elastic members in CD and/or MD;
- a first layer of the parallel yarns running in either the CD or the MD direction;
- a second layer of the hollow elastic members on one side of the first layer, the second layer's hollow elastic members running in the CD or MD direction different from that of the first layer;
- and
- a third layer of the parallel yarns 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 parallel yarns of the third layer are aligned such that the parallel yarns of the third layer nest between the parallel yarns of the first layer without interfering with one another to allow the structure to compact to form a planar structure in a through thickness direction when the fabric is under a compressive load, and
- wherein the hollow elastic members are elastic in their thickness or radial direction and length or axial direction such that under the compressive load the hollow elastic members stretch and compress to conform to the nesting and the structure springs back to substantially the original thickness after removal of the load, and
- wherein the fabric is formed in an endless structure in the form of a continuous loop.
