FABRIC WITH ELECTROMAGNETIC HEATING THREADS Russian patent published in 2018 - IPC D03D15/00 D02G3/22 

FIELD: textile and paper.

SUBSTANCE: invention relates to the textile industry, in particular to electric heating fabrics for industrial and domestic use, having in its structure electric heating filaments. Summary of the invention: a 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 with electromagnetic heating having a second direction perpendicular to the first. Heating threads are made in the form of electrically conductive non-magnetic layered tubular fibers, separate electroconductive layers of which are separated by layers of the insulator. Inside the tubes are fixed magnetized elastic threads of magnetically hard material, and the gap between them is filled with an elastic non-magnetic material or air.

EFFECT: improvement in the operational properties of the fabric, namely, increasing the heating capacity, the flexibility of the threads and the reduction in the mass of the fabric.
