FABRIC WITH ELECTROMAGNETIC AND PIEZOELECTRIC HEATING Russian patent published in 2019 - IPC D03D15/00 H05B3/34 

FIELD: textile and paper.

SUBSTANCE: invention relates to textile industry, in particular, to electric heating fabrics of industrial and household purposes, having in their structure piezoelectric elements and electric heating threads. Fabric is disclosed, which is a web made by thread weaving, and containing main non-electroconductive threads having a first direction, and heating threads having a second direction perpendicular to first, wherein the heating threads are made in the form of electroconductive non-magnetic tubes, inside of which there permanently fixed magnetized elastic threads from magnet-hard material are fixed, and the gap between them is filled with elastic non-magnetic material or air. Electroconductive nonmagnetic tubes are electrically connected to piezoelectric fibers, which are flexible polymer fibers, in the base of which piezoelectric transducers with electrodes from metallized coating are fixed.

EFFECT: higher heating capacity of fabric and more complete use of wind energy and external vibrations.
