A conductive sheet is disclosed, which consists of a nonwoven fabric consisting of 40 to 90 wt % of a heat fusible fiber comprising a vinyl chloride/vinyl acetate copolymer and 10 to 60 wt % of a metal-plated fiber having a fiber diameter of 3 to 50 .mu.m and an aspect ratio of 1,000 to 10,000, wherein the nonwoven fabric is hot-press molded and wherein the conductive sheet has a metal content of 2 to 30% by weight and a specific volume of at most 2 cm.sup.3 /g. The conductive sheet has excellent electromagnetic interference shielding and electrical control effects.

Thin-metal-wire conjugated yarn excellent in suitability for clothing and having EMI shielding which comprises a core composed of a thin metal wire having a diameter of 50.mu. or less and a chemical or synthetic fiber or natural fiber yarn, and another chemical or synthetic fiber or natural fiber yarn as sheath wound round and coated on said core, characterized in that the coating percentage is 70% or more based on the surface area of the conjugated yarn.

An air nozzle for producing a sheath-core type fancy yarn, comprising a hollow cylindrical nozzle body in which a vortex occurs around an axis thereof due to a suction flow of a subatmospheric pressure source. Within the nozzle body a conical cap and a ring body are arranged in series. A sheath yarn is overfed into the nozzle body in the tangential direction to the inner surface of the body and wraps around the conical cap to form a plurality of loops due to the vortex, then entangles a core yarn running straight through the nozzle body. Since an outer surface of the conical cap and a central opening of the ring body guide the vortex smoothly along a yarn path, a fancy yarn having uniformly and tightly entangled loops can be obtained.
