Abstract:

This paper presents a new method and equipment for manufacturing adsorptive materials. The new filter materials are designed for cleaning air from impurities in the form of strongly irritant aromatic or chemical substances. The adsorbent material adopted for the experimental part was a polypropylene fibrous filter material powder-sprayed with fine-granulated active carbon. The active carbon was permanently bonded with the filter material, being partly melted into the surface of its fibres. The adsorbent materials produced, based on carbon-powdered PP stitched nonwovens, were subjected to laboratory tests. The results of the tests showed that these materials were characterised by good end-use properties as a respiratory protective material to safeguard the user against harmful air-borne impurities. The composite adsorbent filter material which we developed can be used in many fields, including air-conditioning, ventilation, hospital equipment, respiratory protective equipment, etc.
