Hi friends...!!
Can I get some suggetions from you friends for making (separating) fibers from a bamboo ? It is a cellulosic material & generally being made
commercially thro' like rayon making process & also thro' some mechanical process like crusing, grinding, etc....
However, I'm not having details about any of these proceses.
Is it possible to make suluble the fibers in something & then extracting/separating....??
I will be eagerly awaiting your suggetions.....

I would suggest soaking them and grinding somehow. Then maybe leaving them for a while to soak some more at temperature before grinding them to a
pulp. Might be usful to boil your mix up to help break it all down. Wood fibres are made this way (high temp and grinding of a mulch) so I guess it
should be simular.
I don't know a chemical way. Certain nonylphenolethoxylates are sometimes used to break pulps down over time - I guess they could work for bamboo
as well?
What are you going to add them to?

Soaking in water followed by steam explosion is a preferred method, I believe. Bamboo is more difficult than many other fiber plants to process,
because of the hard nodes and higher silica contend; not to mention the ecologists and wildlife preservationists who will protest the destruction of
the forests and organise boycotts of your company. Industrial hemp is much easier to deal with.
