摘要： Production method of layered sound absorptive non-woven fabric, which comprises a resonance membrane which is positioned between two layers of the card fibrous web, while both layers of the card fibrous web are produced simultaneously in carding machine, from which each layer of the card fibrous web is separately brought into the device for production of nanofibres through electrostatic spinning, in which to the side of at least one layer of the card fibrous web adjacent to the remaining layer of the card fibrous web a layer of nanofibres is applied, after then both layers of the card fibrous web near to one another until their adjacent sides sit down one on another, they are laid one on another in a selected quantity of layers and the layers join mutually.
