Evaluation of Fibres from Seed and Fibre Flax Varieties (Linum usitatissimum L.) as a Potential Reinforcement of Polymer Composites

For investigation, technical fibres extracted from flax Linum usitatissimum L. fibre variety planted in Croatia and from Slovenian autochthonous variety from Bela Krajina were used. Flax steams of fibre variety were subjected to water retting for 72 hours, but flax steams of seed variety were dew retted for 4 weeks. Dried retted stems were passed through a mechanical process of breaking and scotching, which were followed by heckling and combing, where the fibres were separated in four length groups. Moisture regain, length, fineness and tensile properties were determined for each length group of both varieties. The properties of investigated flax varieties were different but comparable, as well as the properties of individual fibre’s length groups within the same variety. It was concluded that flax fibres from seed and fibre varieties have adequate morphological and mechanical properties for reinforcing polymer matrix composites.
