Technological process: the alpha – high cellulose content of refined chemical wood pulp or cotton linter dissolving pulp as raw material, the alkaline (18% sodium hydroxide), crushing, grinding and other processes, alkali cellulose was made after aging join carbon disulfide Huang Huacheng cellulose xanthate ester, made by sodium hydroxide solution of the orange fibrin glue.

  The glue in the 20 ~ 30 ℃ temperature ripening processing, and filtered to remove impurities and removed the air bubbles, and then in a tension membrane machine consists of a long and narrow the gap in the extrusion, into sulfuric acid and sodium sulfate in the mixture of coagulation bath, form the membrane (regenerated cellulose film), then through washing, desulfurization, bleaching, desalination and plasticizing and ethylene glycol, glycerin, etc.) and other processing, finally through dry.
