The textile light-diffusing member (4) comprises: a first textile layer (10) comprising fibers (14); a second textile layer (11) comprising fibers (15); and a spacing layer (12) arranged between the first textile layer (10) and the second textile layer (11), wherein the spacing layer (12) comprises spacing fibers (16) that space apart the first and second textile layers, the spacing fibers (16) being attached to fibers (14,15) comprised in each of the first and second textile layers to thereby mechanically connect the first (10) and second (11) textile layers with each other. ## Claims ### Claim 1 A light-emitting electronic textile (1; 35) comprising: a flexible component carrier (2) having a plurality of light sources (3) arranged thereon; and at least one textile light-diffusing member (4) arranged to diffuse light emitted by said light sources (3), wherein said textile light-diffusing member (4) comprises: a first textile layer (10) comprising fibers (14); a second textile layer (11) comprising fibers (15); and a spacing layer (12) arranged between said first textile layer (10) and said second textile layer (11), wherein said spacing layer (12) comprises spacing fibers (16) that space apart said first and second textile layers, said spacing fibers (16) being attached to fibers (14, 15) comprised in each of said first and second textile layers to thereby mechanically connect said first (10) and second (11) textile layers with each other. ### Claim 2 (depends on 1) The light-emitting electronic textile (1; 35) according to claim 1, wherein said spacing fibers (16) are attached to said fibers (14, 15) comprised in each of said first and second textile layers by forming loops around said fibers. ### Claim 3 (depends on 1) The light-emitting electronic textile (1; 35) according to claim 1, wherein said flexible component carrier comprises said first textile layer (10). ### Claim 4 (depends on 3) The light-emitting electronic textile (1; 35) according to claim 3, wherein at least one of said light sources (3) is arranged between said first and second textile layers said at least one light sources being arranged to emit light through said spacing layer and said second textile layer. ### Claim 5 (depends on 3) The light-emitting electronic textile (1; 35) according to claim 3, wherein at least one of said light sources (3) is arranged to emit light through said first textile layer, said spacing layer and said second textile layer. ### Claim 6 (depends on 3) The light-emitting electronic textile (1; 35) according to claim 3, wherein said first textile layer (10) comprises a conductive pattern (18a-b) configured to allow electrical connection of said light sources (3) thereto. ### Claim 7 (depends on 6) The light-emitting electronic textile (1; 35) according to claim 6, wherein said conductive pattern is formed by at least one conductive fiber (18a-b). ### Claim 8 (depends on 1) The light-emitting electronic textile (1; 35) according to claim 1, comprising at least one conductive fiber (21) passing from said first textile layer (10) to said second textile layer (11), through said spacing layer (12). ### Claim 9 (depends on 8) The light-emitting electronic textile (1; 35) according to claim 8, wherein said conductive fiber (21) passes back from said second textile layer (11) to said first textile layer (10), through said spacing layer (12). ### Claim 10 (depends on 1) The light-emitting electronic textile (1; 35) according to claim 1, wherein said second textile layer comprises a conductive pattern configured to allow electrical connection of electronic components thereto. ### Claim 11 (depends on 1) The light-emitting electronic textile (1; 35) according to claim 1, further comprising: a third textile layer (25) comprising fibers (28); and a second spacing layer (26) arranged between said first textile layer (10) and said third textile layer (25), wherein said second spacing layer (26) comprises spacing fibers (30) that space apart said first (10) and third (25) textile layers, said spacing fibers (30) being attached to fibers comprised in each of said first and third textile layers to thereby mechanically connect said first and third textile layers with each other. ### Claim 12 (depends on 1) The light-emitting electronic textile (35) according to claim 1, comprising a first flexible light-diffusing member (36) arranged to diffuse light emitted by a first set of light sources (3), and a second flexible light-diffusing member arranged to diffuse light emitted by a second set of light sources, different from said first set of light sources. ### Claim 13 (depends on 1) The light-emitting electronic textile (1; 35) according to claim 1, wherein said light sources are light-emitting diodes. ### Claim 14 A textile substrate for use in a light-emitting electronic textile further comprising a plurality of light sources, said textile substrate comprising: a first textile layer (10) comprising fibers (14) and a conductive pattern (18a-b) configured to allow electrical connection of said light sources (3) thereto; a second textile layer (11) comprising fibers (15); and a spacing layer (12) arranged between said first textile layer and said second textile layer, wherein said spacing layer (12) comprises spacing fibers (16) that space apart said first and second textile layers, said spacing fibers (16) being attached to fibers (14, 15) comprised in each of said first and second textile layers to thereby mechanically connect said first and second textile layers with each other.
