Aerodynamic Web Formation Processes

The process of fiber opening is of great importance for this method because the conveyance in the airflow between opening roller and sieve drum does not lead to an essentially better opening of the fiber structure. Aerodynamic web-forming machines are suitable for the processing of short, thick, and less-curled fibers in order to obtain rougher webs. 

This process has certain technoiogicai advantages compared to other nonwovens technoiogies, nameiy  

In addition, this process is more economicai due to iower investment and maintenance costs combined with a high productivity. The main disadvantage is the technoiogicai iimitation regarding usabie fiber materiai and the reiativeiy high minimum area weight of the nonwoven.
