Abstract
A fabric for use with a paper forming machine comprising a set of MD blended synthetic monofilaments having a first diameter and which are in a five shed Atlas weave pattern with the MD monofilaments passing over four and under one of the CD monofilaments to form a MD monofilament dominant first surface and a CM monofilament dominant second surface. The upper surface of the MD monofilaments are arranged on the first surface to extend along a common plan which is above a plane formed by the uppermost surfaces of the CM monofilaments by an amount equal to at least 5 percent of the diameter of the MD monofilaments. Also, a lower surface of the CM monofilaments is arranged on the second surface to extend along a common plane which is below a plane formed by the lower most surfaces of the MD monofilaments by an amount equal to at least 5 percent of the diameter of the MD monofilaments. The MD and CM monofilaments are comprised of a blend of between eighty percent and ninety-nine percent polyethylene-terephtalate and between one percent and twenty percent fluorocarbon polymers. Accordingly, a fabric having improved wear resistance increased pocket depth and improved paper product release…
