Abstract:
1. A method of making laminar textile construction material for use in acoustic components, said method characterized by the positioning of a construction material comprising a double layer arrangement made by coupling a technical synthetic single-thread fabric surface to a polymeric film surface in an acoustic or electronic product, and that the coupling of said fabric surface and said film surface is made by a hot-melt laminating method comprising feeding a molten plastic resins, preferably a reactive polyurethane applied according to an interspaced joining spot pattern, with a spot density from 30 to 100 spots/cm 2 , said single-thread fabric material has thread with a diameter varying from 24 to 120 microns, a number of threads/cm varying from 20 to 260, and a mesh opening varying from 20 to 250 microns.
