ABSTRACT:
The present invention provides a belt filter press fabric for supporting pressing and draining moisture from a moisture laden web in a press having an inlet end, an outlet end and at least one high pressure nip. The fabric includes machine direction monofilament yarns having selected load bearing, dimensional stability and compressible characteristics. Means for protecting the machine direction yarns from compressive deterioration, such as fibrillation, are provided by interweaving the machine direction yarns with cross machine direction yarns the majority of which have a compressibility characteristic which is greater than the characteristic of the machine direction yarns.
