Studies are made of the ability of fibrous materials obtained by the aerodynamic method (FMAF) to sorb different petroleum products. The oil capacity of materials differing in their main structural indices is determined along with the extent to which they retain petroleum products over time. It is found that these structural indices affect the static sorptivity of FMAFs, and it is shown that an FMAF with a minimum fiber diameter of 3.2 μm and an optimum pore diameter has the greatest capacity to sorb oil.
