Abstract

Stalks of flax varieties viz., DLV1, Himalini and No55 x NL115 were collected from AICRP, MULLARP Scheme,
University of Agricultural Sciences, Dharwad for extraction of fibres in water, chemical and enzymatic retting methods. The
extracted fibres were assessed for quantity and quality parameters viz., fibre yield, fibre length, microscopic appearance and
fibre solubility in different chemicals. The results of the study revealed that, urea retting method yielded higher percentage
of fibres, enzyme retted fibres gave longer length of the fibre. The fibre yield was higher in Himalini variety while the fibre
length was higher in DLV 1 and No55 x NL115 variety. Flax fibres were soluble in 50 per cent sulphuric acid concentrated
whereas insoluble in alkalies and solvents.
