ABSTRACT:
Papermachine clothing comprising a woven or non-woven support layer, a non-woven layer comprising ultra-coarse non-continuous fibers orientated close to the intended running directions of the clothing and two further layers of batt each comprising conventional somewhat finer staple fibers predominantly aligned close to the cross-machine direction. The ultra-coarse non-continuous fiber layer may comprise two such layers, one of which is biassed at an angle A to the running direction X of the clothing, the other of which is biased at an opposite angle B to the running direction X to provide a layer whose fibers while being substantially orientated in the machine direction also have a bi-axial construction with a cross-orientation.
