Abstract (en)
A process for upgrading long, multicelled vegetable fibres or assemblies thereof which comprises the steps of a) submitting long, multicelled vegetable fibres or an assembly based thereon, to a water and/or steam treatment at a temperature in the range of from 130 to 250 DEG C and at a pressure which is at least the equilibrium pressure of the operating temperature, and for a time sufficient to decompose at least part of the hemicellulose present in said fibres. b) a controlled decompression/cooling of the reactor contents, c) isolating the fibres, and d) submitting the isolated fibres in a heating chamber to a temperature in the range of from 140 to 200 DEG C.
