Abstract
A fabric for supporting a fibrous web is disclosed. The fabric has a layer that includes a plurality of weft yarns and a plurality of warp yarns interwoven with the plurality of weft yarns. The warp and weft yarns define a web-facing side and an opposite machine-facing side. The warp yarns include at least one of polyphenylene sulfide (PPS) and polyetheretherketone (PEEK). In addition, a yarn count, weave pattern, and yarn shape of the fabric are configured such that molten polymer drops are scrapable from the web-facing side leaving an upper support surface that does not blemish a fibrous web supported by the fabric.
