Development of small-sized technical line for oil flax processing basing on studying of fiber characteristics

In recent years, an increase in the production of oil flax is observed in Russia. Currently, the task of primary processing of the stem mass of oil flax into natural environmentally safety fiber at a low cost remains relevant. The aim of this work is to study different lines for processing of oil flax from different regions and to determine the characteristics of the resulting fiber. Several types of lines for oil flax processing have been created. A different composition of technological equipment, which is selected depending on the quality of raw materials and finished products, is considered. Comparative studies of low-cost lines are presented, characteristics of short fiber are defined. The line for processing of oil flax in fiber with various values of characteristics is offered, as follows: average mass-length fiber from 52 to 115 mm, average weighted linear density of 4.9-5.5 tex, a mass fraction of shove and admixtures of 26-50%. The recommendations are made. The resulting fiber can be used for the production of various insulation, nonwoven materials, composites, etc.
