FABRIC WITH ELECTROMAGNETIC AND PIEZOELECTRIC HEATING Russian patent published in 2019 - IPC D03D19/00 

FIELD: textile and paper.

SUBSTANCE: invention relates to textile industry, in particular to electric heating fabrics for industrial and household purposes, having in their structure piezoelectric elements and electric heating threads. Fabric is proposed, which is a web made by interlacing yarns and comprising a main non-conductive filament having a first direction, and heating threads having a second direction perpendicular to first, wherein heating threads are made in the form of electrically conductive non-magnetic tubes, inside which periodically fixed magnetized elastic threads from magnetically hard material are fixed, and gap between them is filled with elastic non-magnetic material or air. Electrically conductive 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: technical result is increased heating capacity of fabric and more complete use of wind energy and external vibrations.
