Washing principles

Washing principles Fibres agglomerate into loosely entangled flocs that form a network at low consistency (<1 %).1 The rigidity of the network increases with increasing consistency. The fibre network responds to fluid stress or an external compacting force. This response depends on basic fibre properties, such as fibre size distribution, fibre flexibility and particle dimensions.
