Press felt base fabric exhibiting reduced interference
Abstract:
A press felt formed of two stacked layers of woven single layer base fabric, each layer being formed by warp yarns interwoven with two systems of weft yarns according to a single layer weave pattern. The layers are needled with a batt layer. In the woven single layer base fabric: a) the warp yarns are polymeric monofilaments arranged as a single layer and there are two systems of weft yarns; b) the first system of weft yarns are formed by cabled polymeric monofilaments and the second system of well yarns are single polymeric monofilaments; c) the cabled polymeric monofilaments are 50% to 85% in one repeat; d) the cabled monofilaments are each formed of at least two monofilaments which are cabled together; and e) at least two of the cabled well yarns in each repeat are adjacent to each other.
