Open the CIPO recordAbstract From the Canadian patent
This disclosure shows the use of a composite yarn for the MD strands of an OMS press fabric, designed to be closed by means of a pin seam. The composite yarn includes braided strands of monofilament. The OMS loops formed by the MD strands of the fabric are, as a consequence likewise, braided. As a result, good loop formation and integrity is maintained and the commonly encountered twisting of the loops about axes parallel to the machine direction referred, to as the secondary helix effect does not arise. Braiding, provides the additional advantages of MD extendibility and improved fatigue resistance compared to those observed with a single monofilament.
