Claims
- 1. A papermakers fabric, having top and bottom surfaces, woven from machine direction yarns and one layer of cross machine direction yarns characterized in that the cross machine direction yarns comprise relatively large and small yarns and the machine and cross machine direction yarns are arranged such that the machine direction yarns define floats on one of the surfaces of the fabric and knuckles below said one surface around small cross machine direction yarns, wherein the parts of the machine direction yarns defining the knuckles below said one surface do not extend to the plane of the other surface of the fabric.
- 2. A papermakers fabric as claimed in claim 1, wherein machine direction yarns floating on said one surface of the fabric are made of the same material to machine direction yarns floating on the other surface of the fabric.
- 3. A papermakers fabric as claimed in claim 1, wherein machine direction yarns floating on one surface of the fabric comprise polyester.
- 4. A papermakers fabric as claimed in claim 1, wherein the relatively large and small cross machine direction yarns are provided in alternating fashion in said cross machine direction yarn layer.
- 5. A papermakers fabric as claimed in claim 4, wherein some of the machine direction yarns weave with a float over three cross machine direction yarns and other of the machine direction yarns weave with a float under three cross machine direction yarns.
- 6. A papermakers fabric as claimed in claim 5, wherein each machine direction yarn repeats with respect to four cross machine direction yarns.
- 7. A papermakers fabric as claimed in claim 6, wherein the machine direction yarns are non-circular in cross section.
- 8. A papermakers fabric as claimed in claim 4, wherein the machine direction yarns are non-circular in cross section.
- 9. A papermakers fabric as claimed in claim 8, wherein the machine direction yarns are flat monofilaments having an aspect ratio of about 3:1.
- 10. A papermakers fabric as claimed in claim 1, wherein the inner knuckles which are defined by each machine direction yarn are hidden by a corresponding machine direction yarn woven in stacked alignment in the machine direction.
