Abstract
The invention relates to a process for producing a fibre. The process comprises providing particulate coal, exposing it to a temperature sufficient for plasticisation thereof so as to form metaplastic coal, applying sufficient pressure to the metaplastic coal to extrude it through an orifice and allowing the extruded coal to solidify in the form of a fibre.
