Light emitting textiles

Different techniques are used to combine SEOFs into a light-emitting fabric, however, some are more efficient than others. The present section provides three examples of what has been described in the literamre about the design of light-emitting textiles or textile-like structures. Of course, this is not an exhaustive review since incorporation of optical fibres into textile exists for a variety of other apphcations than photodynamic therapy (from fashion design to data communication [12]). 

Zimmerman, 2013). ZSK Stickmaschinen and the research institute TITV Griez also demonstrate an efficient approach to the manufacturing of light-emitting textiles via embroidery technology and the application of LED sequins (Figure 7.3). 

POFs can also emit light without indentation of the surface fibre or cladding (Figure 8.2). Bending the fibre continuously at a certain rate causes the whole fibre to appear as light emitting. This alternative fits truly for textile construction, hence this option was chosen for this project.

The principle developed here is to integer multiple optical fibre loops and curves within a thin textile substrate, the light being released by macrobendings, as illustrated in Fig. 4.12. With embroidery, the patterns described by the fibres (curves, loops, zigzags etc.) and the substrates (textile, membrane, paper etc.) to which they are stitched define the characteristics of the light emitted by the whole fabric.
