Made to the patent no. p-200702449 for: a thread for fabric with electromagnetic wave attenuation and insulation properties

Abstract

The improvements relate to a thread ( 1 ) with an aluminium core ( 2 ) and a textile covering ( 3 ), the aluminium core ( 2 ) having a diameter of 51 to 1000 micrometres. Another improvement consists of said thread ( 1 ) being used as a covering for a textile fibre ( 4 ), of any length, for forming a rope ( 5 ) which can be used in the formation of fabrics for forming screened meshes for the insulation from electromagnetic waves in buildings.
