Abstract:
1. A process for manufacturing free-flowing pellets containing cellulosic spun fibers, comprising the following steps in sequential order: a) wetting at least one cellulosic spun-fiber strand with a sizing dispersion of a polymer and/or an oligomer to apply sizing, wherein the polymer is selected from a group consisting of starch and its derivates, cellulose derivatives, polyvinyl acetate, polyvinyl alcohol, polyacrylate, and blends thereof, and wherein the oligomer is a dextrin or a derivative thereof, b) drying the at least one spun-fiber strand, and c) comminuting the at least one spun-fiber strand into pellets, wherein the pellets produced by comminuting the strand are free of thermoplastic polymer other than any that may be applied from the sizing dispersion.
