FIELD: textiles, paper.
SUBSTANCE: sheet 2 based on microfibre structure comprises microfibers 1 the diameter of each of which is no more than 3000 nm, and is formed from a mixture which is insoluble in water but soluble in alcohol of resin based on acetated polyvinyl alcohol and insoluble in water but soluble in alcohol of fluorine-based resin. The invention enables to create a sheet to use it as a filter with high filtration characteristics with respect to oil mist.
EFFECT: creation of the sheet based on microfibre structure for use it as a filter.
