Innventia, SP och Swedish ICT har gått samman i RISE för att bli en starkare forsknings- och innovationspartner för näringsliv och samhälle.
Under 2017 kommer att vara en av flera webbplatser inom RISE. Besök gärna för mer information om RISE.

The STFI FiberMaster

The STFI FiberMaster is a powerful tool for studying fibre dimensions and fibre curl and their importance in the papermaking process and resulting paper properties. The equipment is used routinely in Innventia's own research as well as for contract work.

One measurement requires a sample of approx. 0.1 grams of fibres. About 10,000 fibres are analysed in a typical cycle of 20-40 min. All objects with an aspect ratio larger than 4:1 are defined as fibres. All related individual measurement data are reported. It is thus possible to generate a number of detailed 2D- or 3D-diagrams illustrating the properties of the analyzed sample.

The STFI FiberMaster is available as a commercial unit for both laboratory and online applications through Lorentzen & Wettre.
