A process for ripening viscose comprises heating the viscose to a temperature of 35-45 DEG C. by mixing it with substantially dry saturated steam which is at a temperature 5-15 DEG C. above the temperature to which the viscose is to be heated, and maintaining the viscose at a temperature within this range until it has undergone a substantial degree of ripening. A preferred method by which this process may be performed, and an apparatus in which it may be carried out, are described in the Specification 804,881.
