Definitions

  • the present invention relates to an anti-electric-shock garment according to the preamble of claim 1 .
  • Such a garment is known, for example, as a protective garment for technicians who carry out maintenance operations on live high-voltage wires.
  • the activity of the technicians is aimed at minimising the risks of discharge (or short circuit) between two different phases of the high voltage, which may reach potential differences on the order of 800 kV AC or 600 kV DC.
  • the garments known hitherto in the prior art are made of steel wire braided with cotton thread; however, they have a number of disadvantages: their electrical resistance, measured between any two points, is relatively high; they must be ‘activated’ before each use by a strong electrical discharge in order to restore their original electrical conductivity; finally, because of its rigidity, the steel wire gives rise to rigid and uncomfortable garments that hamper the movements of the operators, with a consequent further decrease in the operative safety margins.
  • the object of the present invention is to obtain a protective garment that allows technicians to work with greater safety during operations on live high-voltage wires, with the efficiency of the garment being measured according to the parameters defined by the Standard indicated above.
  • this object is achieved by means of a garment in accordance with claim 1 .
  • FIG. 1 shows a view of a preferred embodiment of a garment according to the present invention
  • the garment 1 comprises at least one first electrically conductive layer whose extent substantially coincides with the extent of the garment 1 itself.
  • This first layer may include a conductive yarn 2 ; advantageously, it is composed exclusively of this conductive yarn 2 .
  • the garment 1 is composed of a substantially complete electrically conductive layer on which can be superimposed other different layers, even partial layers, however without there being substantial portions of the garment 1 where this first electrically conductive layer is absent.
  • the spaces between two adjacent threads need not be considered as areas of substantial discontinuity for the purposes of the present invention.
  • the conductive yarn 2 visible in FIG. 2 may contain silver; for example it may have a core 3 covered by a layer 4 of silver, for example by means of spraying.
  • the core 3 is a polymer, for example composed of polyamide filaments.
  • about 80% of the mass of the yarn 2 is silver.
  • a garment 1 is obtained that is also endowed with antibacterial and bacteriostatic properties.
  • the conductive yarn 2 can also be one of those described in the international patent application with the title ‘CONDUCTIVE TEXTILE YARN’, filed on 22 Mar. 2007 in the name of the holder of the present application, for example produced by braiding a polyamide filament covered with silver with an aramide thread, or twisting together polyamide fibres covered with silver and aramide fibres.
  • the garment 1 is overalls 5 capable of covering the legs, th the operator.
  • the garment 1 also comprises a hood 6 and/or a visor 7 and/or one or more loop fastenings 8 , to cover also the nape of the neck and part of the face of the operator.
  • all these elements are integrated together.
  • the garment 1 can cover also the feet and/or the hands, for example by means of boots 9 and/or gloves 10 integrated with the overalls 5 or that can be connected thereto.
  • the conductive textile product is advantageously a fabric, preferably a knit, for example made with a loom 30 inches in diameter, of fineness 28, with ‘interlock’ weave, and with a weight of 200 g/sqm ( ⁇ 5%) after removal from the machine.
  • the garment 1 comprises, connected in a stable manner to the first layer, at least one second layer that provides the garment 1 with the properties of mechanical and/or chemical and/or flame resistance, as prescribed by the Standard cited initially.
  • a single layer provides all these properties.
  • both the layers are produced in the form of a knit; they can be connected to one another in a stable manner.
  • the second layer can be composed of a second textile product, for example a fibre endowed with anti-flame or flame-retardant properties, such as for example a fibre selected from the group comprising aramide fibres, meta-aramide fibres, treated natura fibres, flame-retardant viscose, flame-retardant cotton, Lenzing FR®.
  • a fibre endowed with anti-flame or flame-retardant properties such as for example a fibre selected from the group comprising aramide fibres, meta-aramide fibres, treated natura fibres, flame-retardant viscose, flame-retardant cotton, Lenzing FR®.
  • the two layers can be coupled together in a stable manner by means of quilting or, more advantageously, by means of coupling (chemical or mechanical) over the entire extent of their contact surfaces.
  • the coupling can be achieved both chemically, that is by placing a resin between the two yarns, for example a flameproof and preferably polyurethane resin, that acts as an adhesive without compromising the elastic properties of the knits, and mechanically, that is by weaving at least one conductive thread for the first layer and at least one thread for the second layer at the same time, but separated, on the same weaving machine.
  • a resin between the two yarns for example a flameproof and preferably polyurethane resin, that acts as an adhesive without compromising the elastic properties of the knits
  • mechanically that is by weaving at least one conductive thread for the first layer and at least one thread for the second layer at the same time, but separated, on the same weaving machine.
  • At least some of the internal stitches between two fabric parts are double and felled and/or overlocked.
  • the garment 1 can include, on the breast, a metal frame covered by a flap 11 .
  • the flap 11 can be closed on the breast of the garment 1 by means of a number of press studs 12 , for example alternating with strips of hook-and-loop fasteners 13 , arranged on the free edge of the flap 11 itself.
  • the garment 1 comprises reinforcing padding, advantageously made of nonwoven material.
  • reinforcing padding advantageously made of nonwoven material.
  • such reinforcements are present in the vicinity of the closure studs 12 or in the vicinity of the hook-and-loop fasteners 13 .
  • the hood 6 of garment 1 can include one or more loop fastenings 8 to protect the neck and the face respectively; to protect the eyes, it has proved to be sufficient to produce a substantially rigid visor 7 , for example reinforced with nonwoven material.
  • visor 7 is sewn to hood 6 by means of a slanting stitch, preferably slanting in the upwards direction, in such a way the and pushed to rotate downwards.
  • the garment 1 according to the present invention thus does not need to include a transparent shield to protect the eyes, which allows an even greater comfort in use.
  • an extremely conductive protective garment 1 has been produced, a garment that is greatly more elastic than the overalls currently available commercially, thus obtaining a garment 1 capable of increasing the safety of the operators both by means of the protection against the external agents in the proper sense (electricity, aggressive chemical and/or mechanical agents, flames), and because it is much more comfortable than the garments known hitherto.
  • This garment 1 is the only one up to now capable of satisfying the Standard IEC 60895:2002.
  • the garment 1 according to the present invention after being subjected to various tests laid down by this Standard, has shown the following results:
