Chemical composition of hemp fibre of the Bialobrzeskie variety after different methods of extraction: dew retting, decortication, osmotically degumming and water retting. Results are expressed as mean ± standard deviation (SD). Lowercase letters (a,b) indicate significant differences at p ≤ 0.05 according to the Tukay’s HSD test [30].
