Abstract
A filter means comprises a non-woven fibre mass in which at least a proportion of the fibres have been shrunk. In a process for the manufacture of the filter means, the structure of a fibre mass which has been physically consolidated by e.g. needling and which contains from 30 to 100% of shrinkable fibres is fixed by subsequent fibre shrinkage. Polyvinyl chloride, polyvinylidene chloride, polyamide and polyester fibres are specified. The filter means may be used for filtering liquids, especially viscous media. The filter means has good particle retention and throughput, while only little work is required for filter cleaning.
