ABSTRACT:
A papermaker's multilayer fabric having at least top and bottom layers of machine direction yarns which are interwoven with cross machine direction yarns systems to establish a first interwoven fabric layer which is bound to a bottom layer fabric with the two being united by interweaving cross machine direction yarns from the bottom fabric layer in the upper fabric layer. The effective pressing surface area of the first fabric layer being equal to or greater than (x+1)+(0.5y). Wherein (x+1) defines the contribution of the upper fabric layer to the effective pressing surface area and the contribution of the binding yarn is defined by the y factor of the equation. Accordingly, the total effective pressing area is defined by the contributions of the upper ply and the binding yarns.
