Claims
- 1. A papermakers fabric comprising a system of CMD (cross-machine direction) yarns interwoven with a system including flat monofilament MD (machine direction) yarns in a selected repeat pattern; said flat MD yarns comprise pairs of upper and lower flat MD yarns stacked in vertical alignment; at least said upper flat MD yarns have an aspect ratio greater than 3:1; said upper flat MD yarns weave in a repeat pattern with at least a first layer of CMD yarns with a float over a selected number of CMD yarns; and said selected number is at least two.
- 2. A papermakers fabric according to claim 1 wherein said upper layer said MD yarns weave in a repeat pattern with a float over three CMD yarns and under one CMD yarn of said first CMD yarn layer.
- 3. A papermakers fabric according to claim 2 wherein said lower layer MD yarns weave in a repeat pattern with a float under three and over one CMD yarns of a CMD yarn layer.
- 4. A papermakers fabric according to claim 3 wherein said CMD yarn system consists of said first layer of CMD yarns and said lower layer MD yarns weave in a repeat pattern with a float under three and over one CMD yarns of said first CMD yarn layer.
- 5. A papermakers fabric according to claim 1 wherein every other flat upper MD yarn is woven with the same repeat pattern with respect to said CMD yarns.
- 6. A papermakers fabric according to claim 5 wherein said MD yarn system consists of only flat MD yarns.
- 7. A papermakers fabric according to claim 5 wherein said CMD yarn system consists of a single layer of CMD yarns.
- 8. A papermakers fabric according to claim 1 wherein said lower flat MD yarns weave in a repeat pattern with a layer of CMD yarns with a float under said selected number of CMD yarns of a CMD yarn layer.
- 9. A papermakers fabric according to claim 8 wherein said lower flat MD yarns have the same aspect ratio as said upper flat MD yarns.
- 10. A papermakers fabric according to claim 1 wherein said lower flat MD yarns have an aspect ratio greater than 3:1.
