Abstract (en)
[origin: WO2018078288A1] The invention relates to a method (1) for producing a high-carbon fibre or group of fibres (2), characterised in that it comprises the combination (100) of a structured precursor (10) comprising a fibre or a group of fibres of hydrocellulose, and a non-structured precursor (15), comprising lignin or a lignin derivative, in the form of a solution having a viscosity of less than 15 000 MPa.s-1 at the temperature at which the combination step (100) is carried out, in such a way as to produce a fibre or a group of fibres of hydrocellulose covered with said lignin or lignin derivative (20), said method also comprising the following steps: a step of thermal and dimensional stabilisation (200) of the fibre or the group of fibres of hydrocellulose covered with said lignin (20) in such a way as to produce a fibre or a group of fibres of hydrocellulose covered with a lignin or lignin derivative deposit (30), and a step of carbonisation (300) of the fibre or the group of fibres of hydrocellulose covered with a lignin deposit (30) in such a way as to produce a high-carbon fibre or group of fibres (2).
