摘要:
The present invention provides a novel needle-punched nonwoven felt fabric which is made of same or substantially similar melting point short fibers of same type or different types, preferably made of one melting point short fibers of same type, wherein the felt fabric is stiff enough to be self-sustaining and has the ability of shape maintenance. The felt fabric exhibits excellent pleatability, moldability and compressive strength. The invention also provides a method for manufacturing the felt fabric, and a filter comprising the felt fabric used as the material of a filter element of the filter, wherein the filter element requires no support structure to stand alone and persistently retains its shape. The present invention further provides use of the felt fabric as a sound absorbing material.

Apparatuses and methods for making and using a filter cloth assembly are described. A filter cloth assembly can have a liquid permeable filtering media attached to a connector ring. The liquid permeable filtering media separates at least one solid from at least one liquid in a slurry. The filtering media has a feed hole formed therein to allows passage of a slurry through the filtering media. The connector ring includes a flange having an upper flange section and a lower flange section. The lower flange section receives an edge of the feed hole to connect the filtering media to the connector ring such that the face of the filtering media is substantially flush with the upper flange section.

摘要:
Die Erfindung betrifft ein Filterelement mit einem Filtermedium und mindestens einem Halter, an dem das Filtermedium befestigt ist. Erfindungsgemäß ist vorgesehen, dass der Halter einen Haltergrundkörper und einen Halteraufsatz aufweist, dass das Filtermedium zumindest abschnittsweise zwischen dem Haltergrundkörper und dem Halteraufsatz angeordnet ist, und dass am Haltergrundkörper und/oder am Halteraufsatz zumindest ein Profilelement zum form- und/oder kraftschlüssigen Halten des Filtermediums ausgebildet ist.
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 %.
