Method for producing a carbon fibre by recycling cotton

The invention concerns a method for producing a carbon fibre, that comprises a step of preparing a continuous fibre made of cellulose from cotton fabrics, by extracting, from these fabrics, cotton in the form of short, discontinuous fibres, and implementing a solvent spinning process; this step being followed by a step of carbonising said obtained continuous fibre made from cellulose, in order to form a carbon fibre. This carbon fibre can be used, in particular, for producing articles made from composite material made from carbon fibres and polymer organic resin.

FIBER PROCESSING METHOD

A fiber processing method includes performing defibration processing on a coarse fragment of a fabric containing a thread in which a plurality of fibers are twisted to produce a first defibrated material; and performing garnetting processing on the first defibrated material to produce a second defibrated material. The fiber processing method may further include, before performing the defibration processing, coarsely fragmenting the fabric to produce the coarse fragment.
