A composite filtering medium comprising a precision fabric, of the type with weft and warp, on the surface of which nanofibres are deposited by electrospinning. A method for producing the composite filtering medium, comprising a step of electrospinning for formation of nanofibres and a subsequent step of deposition of said nanofibres on a base fabric; the method comprises injection of the material for formation of the nanofibres, dissolved in a solvent or mixture of solvents, through a nozzle in order to spread it on an electrode; the method comprising application of a difference of potential between the nozzle and an electrode; the nanofibres being formed as a result of evaporation of the solvent or mixture of solvents, due to the electrical field, and stretching of the polymer deposited on the electrode, by means of the nozzle; the nanofibres thus formed being subsequently stretched and deposited on said base fabric.

Composite filtering medium and method for production thereof

A shaped component made of technical fabric for protection of the speakers of electronic devices with waterproofing characteristics of IPx7 degree or higher, which have water-tight speakers. In addition to the function of protection from solid particles, the invention is optimised for guaranteeing fast and efficient draining-off of the water that has penetrated into the water-tight speaker so as to recover as fast as possible the initial acoustic functionality, in an improved way as compared to the solutions currently available. The component according to the present invention comprises within it one or more openings covered by synthetic technical fabric with hydrophilic treatment, to guarantee rapid exit of the water that has entered the speaker module, and one or more openings covered by synthetic technical fabric with hydrophobic treatment, to favour entry of air into the volume in front of the speaker, thus ensuring proper emptying thereof. In detail, among the various possible embodiments, the present invention may be implemented as a multilayer die-cut part that combines a hydrophilic synthetic fabric with a hydrophobic synthetic fabric and with one or more layers of adhesive to enable assembly inside the end products.
