Definitions

• the present invention relates to a fabric comprising a support and a layer of destructuring of light, characterized in that said layer comprises mother-of-pearl or a substance having diffraction or iridescence properties of light, from the range of UV up to to that of IR, substantially identical to that of mother-of-pearl.
• the present invention also relates to methods for producing said fabric as well as the use of said fabric to produce awning fabrics.
• Canvases are commonly used to protect individuals from solar radiation in the form of umbrellas or blinds. These technical fabrics should ideally allow a strong rejection of infrared rays and UV rays while allowing the passage of visible light.
• US 6159875 discloses a blackout product which is characterized in that the two sides of the product are treated with different pigments.

• the present invention provides novel webs that can achieve infrared rejection of up to 98% while allowing a satisfactory passage of visible light.
• the present invention is based on the diffractive and refractive properties of mother-of-pearl. In existing processes, protection is achieved by infrared rejection by reflection on metal particles that also reject visible light.
• the fabric according to the invention comprises a destructuring layer of the light which acts by diffraction and by refraction. Part of the radiation returns to the light source, another part, diverted from its path loses its force by touching the layer of destructuration of the light tangentially.
• the product according to the invention passes a larger proportion of visible light than infrared.
• Mother-of-pearl has an extraordinary faculty to break the light, the size of its lamellae, close to the wavelength of the targeted radiations, diffracts the light. In addition, the anarchic disposition of these lamellae reorients the radiation in all directions.
• the present invention proposes, in particular, a fabric comprising a support and a layer of destructuring of the light characterized in that said layer comprises mother-of-pearl or a substance having diffraction or iridescence properties of light, from the range of UV to that of IR, substantially identical to that of mother-of-pearl.
