PROCESS FOR PRODUCING SYNTHETIC PULP-LIKE MATERIALS AND PRODUCING SYNTHETIC PAPERS THEREFROM

摘要

Synthetic pulp-like materials are produced by forming into a film a mixed resin comprising at least one orientable thermoplastic resin and at least one thermoplastic resin incompatible or poorly compatible with said orientable resin, stretching the film at a temperature ranging from the softening point of the film to the melting point thereof or a temperature at which an apparent fluidity is shown, then cutting the resultant film in an adequate length to prepare flinders, and fibrillating the flinders by applying a mechanical force thereto.
