Lenzing appear undecided as to whether fibrillation is a good thing or not
Lyocell fibres
are regenerated cellulosic fibres based on the dissolution of cellulose in an
organic solvent, wet spinning of the solution into a coagulation bath, and
complete recovery of the solvent. Lyocell fibres possess high tensile strength
and tensile modulus, and show a high loop and knot strength. The links between
the crystallites in the elementary fibrils in the case of Lyocell fibres are
shorter and better ordered than with modal viscose fibres, which explains their
noted tendency to high fibrillation, particularly in the wet state. As the
elementary fibrils are stiffer and less interconnected than with Modal fibres,
they are more easily separated by mechanical action.
