Abstract
According to an example aspect of the present invention, there is provided a method for producing bimodal and/or multimodal cellulose materials, such as films and filaments, which combine the benefits of cellulosic raw materials having different average size (degree of polymerization) and/or molecular weight distribution.
Claims12
A method for producing bimodal or multimodal cellulose films and/or filaments, the method comprising:
- mixing together cellulose raw materials having at least two different average degrees of polymerization, or at least two different average molecular weights or molecular weight distributions,
- dissolving the mixed cellulose raw materials in a solvent, thereby forming a solution, and
- regenerating the solution into a film or filaments.
