Illuminated fabric comprising glass fibres

Abstract

A luminous woven fabric comprises a woven textile support comprising warp yarns and weft yarns selected from binding yarns and optical fibers capable of emitting light sideways. The binding yarns comprise glass yarns representing at least 50% by weight relative to the total weight of the binding yarns forming the woven textile support.

1 . A luminous woven fabric comprising a woven textile support comprising warp yarns and weft yarns selected from binding yarns and optical fibers capable of emitting light sideways, wherein the binding yarns comprise glass yarns representing at least 50% by weight of the total weight of the binding yarns forming the woven textile support. 
     
     
         2 . The luminous woven fabric as claimed in  claim 1 , wherein the glass yarns represent at least 30% by weight of the weight of the woven textile support. 
     
     
         3 . The luminous woven fabric as claimed in  claim 2 , wherein the luminous woven fabric comprises two faces, at least one of which is used as a lighting surface, and at least one additional coating selected from reflective coatings, structuring coatings, optionally intumescent fire retardant coatings, coatings having a good cleanability and diffusing coatings. 
     
     
         4 . The luminous woven fabric as claimed in  claim 3 , further comprising a fire retardant coating on a face used as a lighting surface. 
     
     
         5 . The luminous woven fabric as claimed in  claim 3 , further comprising a structuring coating on a face that is not used as a lighting surface. 
     
     
         6 . The luminous woven fabric as claimed in  claim 5 , wherein the structuring coating comprises, by weight relative to the total weight of (i) and (ii):
 10% to 60% of binder (i) and   40% to 90% of filling materials (ii).   
     
     
         7 . The luminous woven fabric as claimed in  claim 3 , further comprising an impregnated structuring coating on a face that does not act as a main lighting surface and/or on a face that acts as a main lighting surface. 
     
     
         8 . The luminous woven fabric as claimed in  claim 7 , wherein the impregnated structuring coating comprises, by weight relative to the total weight of (i) and (ii):
 70% to 100% of binder (i) and   0 to 30% of filling materials (ii).   
     
     
         9 . The luminous woven fabric as claimed in  claim 3 , wherein the structuring coating is reflective. 
     
     
         10 . The luminous woven fabric as claimed in  claim 3 , further comprising:
 a structuring coating on a face that is not used as a lighting surface, and   an additional coating selected from optionally intumescent fire retardant coatings, coatings having a good cleanability and diffusing coatings on a face used as a lighting surface.   
     
     
         11 . The luminous woven fabric as claimed in  claim 1 , wherein the optical fibers have a diameter of between 100 and 1000 μm. 
     
     
         12 . The luminous woven fabric as claimed in  claim 1 , wherein the warp yarns comprise sized glass yarns used as binding yarns. 
     
     
         13 . The luminous woven fabric as claimed in  claim 1 , wherein:
 the optical fibers have a diameter greater than or equal to 500 μm and are used as weft yarn and/or as warp yarn in a density of at least 8 yarns/cm, and   the warp yarns comprise sized glass yarns used as binding yarns.   
     
     
         14 . The luminous woven fabric as claimed in  claim 1 , further comprising at least one light source connected to at least one end of an optical fiber. 
     
     
         15 . A process for manufacturing a luminous woven fabric as in  claim 1 , comprising:
 weaving optical fibers and binding fibers so as to form a woven textile support, the binding fibers comprising glass yarns represent at least 50% by weight of the total weight of the binding yarns forming the woven textile support.
