FILTERING MATERIAL, METHOD OF PRODUCING SAID MATERIAL AND RESPIRATOR Russian patent published in 2009 - IPC B01D39/16 

Abstract RU 2376053 C1

FIELD: chemistry.

SUBSTANCE: invention relates to making filtering materials for respirators. Filtering fibre material is proposed, as well as a method of making said material by electrostatic moulding microfibres from a polymer solution in an organic solvent. The material contains fibre of diametre 1-10 mcm from chlorinated polyethylene, characterised by mass content of chlorine of 60-70%, has surface density of 20-60 g/m and is used as the working layer of the respirator.

EFFECT: high mechanical strength of the material with high retention potential.
