FIELD: woven fabrics for magnetic systems and radioactive radiation shields.
SUBSTANCE: proposed ferromagnetic fabric characterized in enhanced strength and magnetic characteristics, ability of absorbing and dissipating electromagnetic radiation has warp, polymeric binder, and powdered ferromagnetic material. Fabric warp is made by linen weave method. Warp threads and shoot wires are made of alternating lavsan and magnetically soft single threads. Number of threads per meter is 5 000 to 7 000. Magnetically soft threads are made either of supermalloy or molybdenum permalloy with diameter measuring 0.05 to 0.1 mm; linear density of lavsan threads is 10 to 20 tex. Proportion of fabric ingredients is as follows, mass percent: lavsan thread, 10-15; magnetically soft single threads, 20-25; binder (acrylic copolymers), 10-15; highly coercive alloy powder, 50-55.
EFFECT: enhanced radioactive radiation shielding efficiency of fabric.
