Abstract
A process for sclerenchyma fibers, in particular flax, includes mechanical treatment accompanied by formation of a fiber strip and alignment of the fibers essentially parallel to one another. The fibers of the fiber strip are freed of wood constituents, greases, pectins and other impurities by a chemical and/or cooking treatment of the fiber strip. The treated fiber strip is dried and then divided into shorter sections. These sections are at least partly pulled apart or opened to form fiber bundles. The fiber bundles are carded at a set moisture content of at least 10%-wt. and combined to give a fine fiber strip.
