Three recently-suggested non-derivatising solvent systems for the spinning of quality rayon fibres are reviewed and compared. They comprise amine oxide, liquid ammonia/ammonium salt, and lithium chloride/DMAc systems. It is concluded that both amine oxide and LiCI/DMAc systems produce good quality rayon fibres, and appear to be competitive with a new viscose plant from the initial investment and operating economic viewpoints. Areas in which future research efforts should be concentrated are identified.
