Retting of flax and characterization of fibres

Flax (Linum usitatissimum L.) is an important commercial crop that supplies both linseed and bast fibres for multiple applications. Retting, which is a microbial process, separates industrially useful bast fibres from non-fibre stem tissues. Several methods (i.e., water- and dew-retting) are used to ret flax. The paper presents the results of research focused on agronomic properties (stem yield after retting, total fibre yield, share of total fibre, long fibre yield and share of long fibre) and textile- technological properties (length, fineness and tenacity of fibres) of cultivar of fibre flax, Viola after traditional retting in very soft, medium hard and hard water. With the investigation of different water hardness influence in the process of retting flax fibre, the effect of ultrasound on retting process was also studied. Based on a research of agronomic and textile- technological properties of fibre it has been found that ultrasound retting proved an environmentally friendly process of retting flax fibre with saving time and energy.
