resistance of polypropylene nonwoven fabric manufactured using the mechanical carding process and
bonding using the needling process, where a part of the samples was additionally bonded by the thermal

thermal conductivity. A change of the average value of thermal resistance after calendering related to
non-calendered fabric mass between 150 and 500 g/m² ranged from 53.9 to 41.0%. With increasing
nonwoven fabric mass, the difference between thermal resistances of needled and needled as well as
