Abstract

The technology has been proposed for manufacturing a textile material that contains ferromagnetic nanoparticles for shielding electromagnetic fields. It has been shown that the most effective method of sticking together between nano-particles and the fibers of the textile material is the application of magnetic liquid with nanoparticles on the material and its exposure in a heterogeneous permanent magnetic field. Under the condition of a magnetic field intensity of 450 A/m and the exposure to it for 12 hours, the implantation of the nanoparticles into the linen fabric becomes almost irreversible. The protective properties of the developed material have been investigated. When impregnated with a magnetic liquid in the amount of 45–50 g/m2 (a ferromagnetic particle content of 9 % by weight), the material's shielding coefficients for 1–3 layers amount to: for the electric field of industrial frequency 1.4÷4.8; for a magnetic field, 1.9÷8.1. Following the magnetic treatment, these indicators are 2.9÷8.6 and 2.3÷8.9, respectively. In order to remove technological components such as vacuum oil and oleic acid from the magnetic fluid, it would suffice to apply a synthetic detergent, which has been confirmed by experimentally.

We have investigated the efficiency of the obtained result under actual industrial conditions. It was established that the decrease in the magnetic field intensity of industrial frequency and its inter-harmonics by a single layer of the impregnated material without magnetic treatment is 1.4, with a magnetic treatment ‒ 2. In this case, there is no significant decrease in the level of the natural geomagnetic field. We have modeled the distribution of a magnetic field in the human body for the case of manufacturing a protective suit from the developed material. Under the conditions of a warranted reduction in the magnetic field intensity by 2 times in critical places, an increase in the field level is observed in the cervical region due to the increase in the magnetic resistance in this region. This should be considered when designing the protective suit configuration
