Abstract
This paper studies water absorption and processes of thermooxidative destruction and biodegradation of film and nonwoven fibrous materials based on the natural polymers polylactide and polyhydroxybutyrate. Nonwoven fibrous materials were obtained by electrospinning, and film fibrous materials were obtained by watering onto the glass surface. It was determined that fibrous materials have high water absorption and a high oxidation rate in comparison with film materials, which significantly accelerates (by about five times) the processes of biodegradation under environmental conditions. Fibrous nonwoven material from biodegradable polymers is an important development as a disposable soil mulching material and a covering material that has a service life of less than 1.5 months under natural conditions.
