POLY 686 |
| By using a wide variety of native cellulose sources and many aqueous and non-aqueous solvent systems, we are able to propose a systematization of the different dissolution modes of a native cellulose fiber. Two major parameters are playing a role. The first is the structure of the fiber, and mainly if the cellulose chains are twisted or not inside the fiber, and of course the quality of the solvent. We will show the influence of free ends and of the tension of the fibre on the dissolution mode. Tension may completely prevent cellulose to dissolve. We will explain how the morphology of the fibre is explaining such features. |
