Engineered textile yarn

Abstract

The present invention relates to integral protective overalls for operations on uncovered high-voltage cables, comprising a first electrically conductive layer whose surface area is substantially equal to the surface area of the overalls and that is obtained from a polymer fibre covered with silver. The overalls of the present invention can also include a second layer connected to the first layer in a stable manner.

       14 . A protective anti electric-shock garment for operations on uncovered high-voltage cables, comprising a first electrically conductive layer, wherein the surface area of the said first layer is substantially equal to the surface area of the said garment. 
   
   
       15 . A protective anti electric-shock garment according to  claim 14 , wherein the said first conductive layer is obtained from a conductive yarn covered in silver. 
   
   
       16 . A protective anti electric-shock garment according to  claim 14 , comprising at least one second yarn having flame-retardant properties, obtained from a polyaramide fibre. 
   
   
       17 . A protective anti electric-shock garment according to  claim 16 , wherein the said first and second layers are coupled together in a stable manner over the entire extent of the surfaces of mutual contact of the said first and second layer. 
   
   
       18 . A protective anti electric-shock garment according to according to  claim 14 , wherein the shielding efficiency, measured according to Standard IEC 60895:2002, is greater than 20 dB, preferably greater than 70 dB. 
   
   
       19 . A protective anti electric-shock garment according to  claim 14 , comprising trousers, a covering for the abdomen, and sleeves, produced without a break in continuity between them. 
   
   
       20 . A protective anti electric-shock garment according to  claim 14 , comprising boots and/or gloves, each capable of being joined to the said garment by means of at least two press studs having a diameter of not less than 10 mm. 
   
   
       21 . A protective anti electric-shock garment according to  claim 20 , refolded in correspondence with these press studs, in such a way that the said conductive layer is present with continuity also to the inside of the said garment, in such a way as to form an electrical contact both with the external portion and with the internal portion of the said press studs. 
   
   
       22 . A protective anti electric-shock garment according to  claim 14  that comprises double or overlocked stitches. 
   
   
       23 . A protective anti electric-shock garment according to according to  claim 14  that comprises a hood capable of being arranged around the head of the user, the said hood being such as to leave only the face uncovered. 
   
   
       24 . A protective garment according to  claim 23  wherein the said hood is equipped with one or more loop fastenings capable of being arranged around the face in such a way as to leave uncovered only the eyes of the user. 
   
   
       25 . A protective anti electric-shock garment according to  claim 23  wherein the said hood comprises a rigid visor. 
   
   
       26 . A protective anti electric-shock garment according to  claim 25  wherein the said rigid visor is sewn to the said hood by means of a stitch slanting in the upwards direction, in such a way as to impart to the said visor a torque that tends to rotate it towards the face of the user.
