A papermaker's fabric, designed for use as a base fabric for a TAD belt, but also usable on the forming, press and dryer sections of a paper machine, has a plurality of warp yarns interwoven with a plurality of weft yarns. The warp yarns are of two types. Those of the first type weave with the weft yarns in a plain weave, while those of the second type weave with the weft yarns in a 2×2 twill weave. The warp yarns of the first type alternate with those of the second type, which undulate between adjacent yarns of the first type to give the fabric a desired openness.

1. A papermaker's fabric for use as a base fabric for a TAD belt, or for the forming, press and dryer sections of a paper machine, said fabric comprising:a plurality of warp yarns interwoven with a plurality of weft yarns, some of said warp yarns being of a first type and some of said warp yarns bei
1. A papermaker's fabric for use as a base fabric for a TAD belt, or for the forming, press and dryer sections of a paper machine, said fabric comprising:a plurality of warp yarns interwoven with a plurality of weft yarns, some of said warp yarns being of a first type and some of said warp yarns being of a second type, said warp yarns of said first type interweaving with said plurality of weft yarns in a plain weave, and said warp yarns of said second type interweaving with said plurality of weft yarns such that each said warp yarn of said second type alternately passes over and under successive pairs of adjacent weft yarns on a repeating pattern, wherein warp yarns of said first type alternate with warp yarns of said second type, said warp yarns of said second type undulating between adjacent warp yarns of said first type to give said fabric a desired openness. 2. A papermaker's fabric as claimed in claim 1, wherein each warp yarn of said first type is between two successive warp yarns of said second type. 3. A papermaker's fabric as claimed in claim 1, wherein each warp yarn of said second type is between two successive warp yarns of said first type. 4. A papermaker's fabric as claimed in claim 1, wherein said warp yarns of said second type undulate between points where a weft yarn passes over a warp yarn of said first type and a warp yarn of said second type. 5. A papermaker's fabric as claimed in claim 1, wherein said warp yarns are oriented in the machine direction of said paper machine, and said weft yarns are oriented in the cross-machine direction. 6. A papermaker's fabric as claimed in claim 1, wherein at least some of said warp yarns are monofilament yarns. 7. A papermaker's fabric as claimed in claim 1, wherein at least some of said weft yarns are monofilament yarns. 8. A papermaker's fabric as claimed in claim 1, wherein at least some of said warp yarns are polyester yarns. 9. A papermaker's fabric as claimed in claim 1, wherein at least some of said warp yarns are polyamide yarns. 10. A papermaker's fabric as claimed in claim 1, wherein at least some of said warp yarns are polyphenylene sulfide yarns. 11. A papermaker's fabric as claimed in claim 1, wherein at least some of said warp yarns are modified heat-, hydrolysis-, and contaminant-resistant polyester yarns. 12. A papermaker's fabric as claimed in claim 1, wherein said warp yarns of said second type are opaque to ultraviolet (UV) radiation. 13. A papermaker's fabric as claimed in claim 1, wherein at least some of said weft yarns are polyester yarns. 14. A papermaker's fabric as claimed in claim 1, wherein at least some of said weft yarns are polyamide yarns. 15. A papermaker's fabric as claimed in claim 1, wherein at least some of said weft yarns are polyphenylene sulfide yarns. 16. A papermaker's fabric as claimed in claim 1, wherein at least some of said weft yarns are modified heat-, hydrolysis-, and contaminant-resistant polyester yarns.
