Development of novel film using paramylon prepared from Euglena gracilis

摘要

A novel film was developed using paramylon from Euglena gracilis and its physical properties were investigated. Formic acid was suitable for the preparation of a solution of paramylon, and a transparent even yellow film was obtained by casting the solution on a glass plate and drying the cast film in air without using coagulation bath. However, the spinability of a paramylon solution was fairly low, The spinability was a little enhanced by blending polyvinyl alcohol (PVA) up to 70%. The paramylon/PVA blend fibers were produced through wet spinning using coagulation bath of conc. Na2SO4 at a room temperature. (c) 2006 Wiley Periodicals, Inc.
