The present invention concerns a thermal drawing method for forming fibers, wherein said fibers are made at least from a stretchable polymer. The present invention also concerns drawn fibers made by the process.

Multi-material stretchable optical, electronic and optoelectronic fibers and ribbons composites via thermal drawing

The method for drawing a fiber with a textured surface comprises the following steps: &#x2014;forming of a preform from which the fiber is to be drawn with a textured surface; &#x2014;addition of an outer layer to the textured preform to preserve the shape of the texture of the preform surface during the drawing operation; &#x2014;drawing of a fiber from the preform, whereby the fiber keeps the formed texture of the preform surface and &#x2014;removing the additional outer layer to leave the original surface textured fiber exposed. The obtained fiber can be used as a mold to form a textured hollow channel in another material, as a surface coating and as a pressure detector.
