Flax (Linum usitatissimu) is one of the major crops used in the food and chemical industries for the production of linseed oil in Canada. To make linseed oil, the seeds are crushed, and the resulting cake is used for fodder. In addition, seed oil boiling is used in the manufacture of paint, varnish and ink printing. In the production of natural fibres, the deterioration of flax fibres is a key factor. The main degradation behaviour of flax fibres is regulated by cellulose. The separation of fibres and fibre bundles from non-fiber tissues in the stems is the retting of flax. Different methods of treatment of Bast fibres may include retting, splitting, scutching, hackling, and combing. It is necessary to extract the lignin and partially retain the pectin in order to bleach the flax and to maintain the fibre tenacity high enough. The issue of classical hydrolyzing treatment with alkalis and oxidizers is attributable not only to the impact of these chemicals on pectin and lignin, but also on the cellulose itself, resulting in a drastic reduction in the strength of the material.
