Flax fiber is the most valuable, rapidly renewable source of cellulose. To isolate cellulose from the fiber, it is necessary to get rid of its non-cellulose components: lignin, pectin substances, waxes and hemicellulose. These substances can be removed by cooking flax fiber in an alkaline solution. To intensify the process of destruction of the non-cellulose complex, it is proposed to use the energy of the electromagnetic field of ultrahigh frequencies. The article presents the results of theoretical and experimental studies aimed at establishing the dielectric characteristics of the system components, which make it possible to prove the effectiveness of the effect of the microwave field on the process of destruction of the non-cellulose complex and to deduce the permissible limits of technological parameters. For the effective management of the technological process of alkaline cooking, the dielectric characteristics of the system components are established on the basis of theoretical and experimental studies. To solve this problem, the system was divided into components: fiber, solution, heterogeneous system. Further, the characteristics of each component are determined separately. The established characteristics showed the following values: the dielectric constant of the fiber in the solution reached a value of 24.8, the dielectric constant of the solution-73, the dielectric constant of the heterogeneous system is 64.55. These values allow you to conduct the technological process of delignification with high efficiency indicators.
