摘要: The invention lies in the field of filter cloths. For example for manufacturing grinding compounds and the like the mass consisting of (abrasive) grains must be removed from a liquid or viscous-liquid mass by guiding this mass with pressure through a filtering unit, for instance a so-called 'plate filter' which comprises at least one filter cloth. This filter cloth is placed under strain of pressure by throughput of the mass with force, whereby tensile forces occur in the cloth. For this reason use is made for this type of application of fabrics of which the threads/yarns can be placed under strain of tension. The fabric must further be very well able to withstand the heavy mechanical influence of grains being partly held back and partly allowed through. The invention provides a fabric for use as filter cloth, which fabric comprises polymer material which consists of filaments/fibres with a parallel orientation of at least 80 %.
