FIELD: medicine, life saving equipment.
SUBSTANCE: mould respirator is made of a single-component monolayer nonwoven cloth containing a fibre mass fraction/size bimodal mixture of plexiform continuous single-component polymer microfibres and greater fibres of the same polymer structure. The cloth is loaded, moulded in a cup porous single-component monolayer matrix with fibres attached to each other in certain fibre cross points. King's stiffness ratio of the matrix exceeds 1 H.
EFFECT: while moulding the respirator, the layers improving rigidity, two-component fibres or other means for filter-bed reinforcement are not required, besides the respirator is easily reprocessed.
