<p>A yarn for the production of knitted articles having good properties of attenuation of low frequency and medium frequency electromagnetic fields. The yarn comprises a base yarn (1,2) made of natural or artificial fiber, such as cotton, wool, rayon and the like, to which a carbon yarn (3) is embodied in a percentage not lower than 1%. The attenuation of the intensity of the electromagnetic field at 50-60 Hz is higher than 30 times. <IMAGE></p> |
