Lyocell

Index

In comparison to the manufacturing process of conventional viscose fibres lyocell is manufactured by a solvent-spinning process. The cellulose is directly dissolved in the solvent N-methyl-morpholine-N-oxide (NMMO) containing just the right amount of water. The solution is then filtered and wet spun to filament fibres. Because of the fact that in this spinning process the NMMO solvent is recovered and reused the lyocell manufacturing process is very environmentally friendly.
