  • Patent number: 6294489
    Abstract: The textile conveyor belt of the invention is constituted by at least two layers, namely an outer layer designed to come into contact with articles and an inner layer designed to come into contact with a mechanical conveyor system. Cohesion between the layers is provided by binding threads, the outer layer and the binding threads being made of threads that are made up of an intimate mixture of fibers comprising both stainless steel fibers and fibers of a material selected from those which decompose into carbon when raised to high temperature, e.g. para-aramid or polybenzimidazole. In addition, the inner layer is made of threads having good properties concerning both mechanical strength and resistance to temperature.

  • Patent number: 5981066
    Abstract: Applications of a metallized textile. The textile is activated by precipitating noble metal nucleation sites on the fibers of the textile. Immersing the activated textile in a suitably prepared solution of a metal cation, and adding a reducing agent, leads to the formation of a metal plating tightly and intimately bonded to the fibers of the textile. Exposure of the metallized textile to air oxidizes the surface of the metal plating. Applications of the metallized textile include acaricides, fungicides, bactericides, armor, electrodes, anti-static devices, RF shielding, and radar reflectors.
