ABSTRACT
The World Health Organization has declared the coronavirus an emergency of international importance. In this regard, non-woven materials (NM) are recommended to be actively introduced and used to stop the spread of coronavirus in products for various purposes, including medical devices. Synthetic polyester fillers in pillows, blankets, mattresses, insulation in clothes and buildings are nonbiological non-cellular structure. It does not spread bacteria, which, in turn, like living organisms, microorganisms, can be a medium for viral spread. The fibers used in the production of Hollofiber® materials have a hygroscopicity of less than 1%, they do not have a protein component or a plant cell, which can be a nutrient medium for microorganisms and, accordingly, viruses spread through them. However, the issues of viral transfer and virulence remain relevant and problematic. One effective solution is radiation sterilization. The problem is that not all nonwoven materials (NM) are able to withstand exposure to radiation sterilization. In connection with this object of research, a high-tech NM of domestic production was selected. Thus, the study of the effect of radiation sterilization on Hollofiber® material is an urgent task. As a result of studying Hollofayber® NM after radiation in the dose range from 20-60 kGy, there were no significant changes in consumer characteristics. Thus, NM Hollofayber® PROFI, article P 35191, Hollofayber® SOFT, article P 5197, Plollofayber® SOFT, article P 5200 are recommended for the manufacture of medical devices. © 2021 Ivanovo State University of Chemistry and Technology.
