<p>The compact formation contains a matrix which can be prepared through compaction of a layer or layers of non-woven fabrics and also a component of discrete particles originally situated in this layer or layers of non- woven fabrics retained in the filtering mechanism. That may be a polymer matrix which can be prepared through the compression of the filtration layer or layers of non-woven fabrics with fibers made of polymer materials, fibres made of biopolymer materials, microfibers and/or nanofibers. A used waste filter may also be a layer of the filter. The functional and/or modifying additive aimed to control the resulting properties of composite material (additive showing an activity in the electric or magnetic field, additive to particles of biological material, or additive to particles with bioactive, biocidal, and/or antibacterial effects may then be a component of discrete particles. A component of discrete particles may also be an additive based on cross-linked powder elastomer as well as particles of toxic material encapsulated in the matrix, which enable their very easy and effective disposal. Furthermore, the invention deals with the preparation of compact formation of composite character.</p> |
