    Abstract: The invention is directed to a multilayer fabric comprising: a) an external woven fabric; b) an internal woven fabric; c) a membrane placed between the internal fabric and external one, said membrane comprising at least two layers, one of which having a superior UV refractive index compared to the other one; d) an additive comprising a ceramic compound.
    The multilayer fabric according to the invention shows a very high UV refractive index and gives a better perceived temperature under the fabric compared to the ones on the market.
    In a preferred embodiment, the membrane has a thickness comprised between 35 and 200 µm, and is a polyurethane membrane having a number of layers which can vary from 2 to 3.
    The external and internal fabrics are preferably independently selected from: polyester, acrylic, polyamide.
    The multilayer fabric according to the present invention is suitable for use in awnings, camping tents and car hoods.
