Features of the chemical composition of scutched flax fiber grown in various regions of Belarus

Experimental investigations of the chemical composition of scutched flax fiber varieties "Vasilek" and "Grant", grown in various regions of the Republic of Belarus, were carried out in order to establish the differences in chemical composition depending on the variety and growing region. The relationship between the chemical composition of the fiber and its number has been studied. It was found that the content of lignin decreases and content of cellulose increases when the fiber number increase. It was shown that the content of the main biopolymers of fiber of one variety differs in a wide range depending on the growing region. It was found that the specific breaking load of flax complexes correlates with the content of cellulose and lignin.
