- Annotation: The article considers the possibility of creating a combined process of forming a non-twisted wet rov- ing and preparing it for spinning in order to obtain linen yarn. In the process of preparing the roving for spin- ning, an electrochemically activated aqueous solution (catholyte) with a redox potential of En = + 900 mV and a pH of pH = 10 was used. The corresponding technological regimes of the combined process of roving for- mation are determined. In the course of the experiment, the influence of the method of obtaining the roving (twisted and traditional twisted) on the quality indicators of the yarn was also tested. The paper presents the physical and mechanical properties of yarn obtained from twisted and twisted roving. It is shown that the use of an EChR solution when forming a twistless roving by the wet method and wetting it with this solution in the trough of a spinning machine makes it possible to obtain linen yarn of medium linear density with im- proved physical and mechanical properties compared to that produced from a roving obtained by traditional technology. It has been established that the twistless roving produced by the proposed technology has a sig- nificantly lower hairiness than the traditional twisted one.
