The fibres are extremely pure due to a complex extraction process during production. The fineness of the individual product types is determined by special grinding and fibrillation of the various fibres.

Long fibres especially for initial precoating. The fibres have a smooth surface structure, which prevents “snagging” in the supporting tissue. The length of the fibres also compensates for irregularities in the support fabric and thus ensures safe bridging on the support fabric.
