Abstract

The characteristics of bast fibres from flaw and hemp are discussed in thecontext of novel applications in nonwovens and composites and as raw materials for bulk paper production. Elementary flax fibres have been produced by a novel chemimechanical process developed at ATO-DLO. we have shown on a laboratory scale that these flax fibres can replace synthetic polypropyleneand polyester fibres in wet-laid nonwovens. The obtained sheets showed good web formation and acceptable sheet characteristics. Composites of different polypropylene/flax mixtures resulted in good mechanical properties. Delignification and extraction of the fibre or the addition of a coupling agentimproved fibre/matrix compatibility and increased the composite strength considerably Remarkably flax and hemp fibres which were compounded at temperatures up to 260 degrees C preserved the fibre-reinforcing activity. Peroxide bleached mechanical pulps from hemp bast fibres produced with an APXP extrusion pulping method can compete with a variety of wood pulps.
