Abstract:

The influence of the technological parameters of the padding process on the filtration properties of polyester nonwoven fabrics was analyzed. The variables were surface weight and binding agent concentration. The filtration properties were indirectly analyzed by pore size measurements and pore size distribution. The results obtained proved that the surface weight of webs strongly influenced the volumetric air flow of the tested nonwoven fabrics.

Tags: pore sizes distribution, filtration, nonwovens, padding.
