FILTERING MATERIAL, METHOD OF PRODUCING SAID MATERIAL AND RESPIRATOR

摘要

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. ^ 4 cl
