Latest Patents

Epstein holds a patent for the "Production of cellulose acetate filamentary material." This patent describes an improved process for forming cellulose acetate filamentary material and film. The process involves dissolving secondary cellulose acetate in a solvent at elevated temperature and pressure to create a homogeneous solution. The solvent used is incapable of dissolving the secondary cellulose acetate at ambient conditions. The cellulose acetate solution is then extruded through a shaped orifice into a gaseous atmosphere at substantially atmospheric pressure. This results in a rapid precipitation or phase separation reaction, allowing the solvent to separate from the cellulose acetate and form a solid filamentary material or film, which is subsequently collected. The solid product can be dried to remove any remaining traces of solvent. This innovative process is capable of implementation at rapid spinning speeds while utilizing relatively short zones for phase separation.
