Enhanced fibre

Abstract

A method of enhancing a fibre from a staple fibre precursor comprising: obtaining a staple fibre precursor, tensioning and aligning the fibre precursor along a fibre axis and subjecting the aligned staple fibre to an oxidation process, wherein the oxidation process comprises subjecting the tensioned fibre precursor to a general gradient of increasing temperatures in successive multiple stabilisation/oxidation ovens, the ovens ranging in temperature from 50 to 500 degrees Celsius.
