Abstract
Processing sized fiber products to recover reinforcing fibers by removing fiber sizing material from the reinforcing fibers. The processing includes first treating the sized fiber product with a normally-liquid first solvent for fiber sizing material followed by removal of the first solvent from the first solid residue including reinforcing fibers. The removal of the first solvent from the continuous reinforcing fibers may include heating the fibers and/or second treating the first solid residue with a normally-gaseous material contacted with the solid residue under conditions of temperature and pressure at which the normally-gaseous material is in a liquid or supercritical fluid form. The processing may be performed in a continuous manner to recover the continuous reinforcing fibers in a continuous form.
