Tube filters are normally produced using needle punched nonwovens because they can easily be combined with other textile structures. In Europe and the USA a significant quantity of needle punched nonwovens are used as filters with supportive fabrics. The supporting textile fabric offers the filter good durability and also provides a small amount of elongation, which is an advantage for the cleaning of the filters. Using different production methods, tube filters with a range of properties can be made, e.g. filters with different weight per unit area(50-2500 g/m2), varying thickness, porosity, etc. The fibres used for there filters need to processes a wide range of properties, for example, resistance to chemical, mechanical and biological effects, which might arise from either the particles or the surrounding fluid. If rigid media are needed, this property can be achieved by chemical or thermal bonding. During processing, the surface of the filter can be finished using chemical treatments to increase durability, filter cake formation and also the ease of cleaning of the filter. Depending upon the usage environment, a filter surface can either be made smooth or rough. The efficiency of these filtration media increases with increasing build up of filter cake. There is a need for the filter to be cleaned by a simple process, for example, pressure pulses or vibration, even when the filtered material adheres strongly to the filter.
