Abstract
Kazakhstan has become a leading grower and exporter of linseed; however, domestic enterprises are unable to ensure a complete cycle of processing of these crops. Especially pressing is the need for rational use of the stem biomass, which is simply wasted or burnt, causing irreparable damage to the ecosystems of the regions where it grows. The main problem of fiber in Kazakhstan is the lack of appropriate technology for bast fiber processing and the lack of specialists in this field. In search of ways to extract and spin linseed fibers, the authors of this article made an attempt to use worsted machines designed for wool for these purposes. The fibers obtained have satisfactory values for the following spinning process.
