Abstract
A process for manufacturing free-flowing pellets based on cellulosic spun fibers. The process includes a) wetting at least one cellulosic spun-fiber strand with a preferably aqueous dispersion of a polymer and/or an oligomer for the purpose of applying sizing, b) drying the at least one spun-fiber strand, and c) comminuting the at least one spun-fiber strand into pellets. The free-flowing pellets are made from at least one comminuted spun-fiber strand having sizing made from a polymer and/or an oligomer. A fiber-reinforced thermoplastic includes finely distributed free-flowing pellets for manufacturing fiber-reinforced performs.
