Abstract
In this work, research has been carried out on changes in the linear density of bast fibers during processing on a hammer, clog and carding machine. Physical and mechanical properties of fibers before and after processing are determined. According to the results of the study showed that the linear density of fibers on the meat machine does not depend on the number of treatments, the average fineness of hemp fibers after the meat machine is 25.8 tex. In addition, the study shows that it is possible to offer a technology for processing short hemp fiber, after which you can get a more bleached and thinner linear density fiber. The average fiber fineness after all technological processes on the grinding machine, hammer mill and carding is 21.3 tex.
