6. Conclusion and outlook

Despite its long history, the textile spinning process continues to evolve towards the production of increasingly high-performance fibers meeting specific needs.

We have not mentioned carbon fibers in this presentation, but it is well known that they are produced, for the most part, from PAN precursor continuous multifilaments (using a modified process, but still of the "wet collodion" type, compared with that described for the Courtaulds plant in Grimsby); this principle of transforming an organic fiber into a mineral fiber with high mechanical and thermal performance also exists in the field of ceramic fibers, and it's safe to assume that other examples of this type will see the light of day in the more or less near future.

The most interesting fact to note, however, is this: compared with the viscose process, which is more than a century...
