The SEM images by Evgenia Kollia and colleagues illustrate the degradation of flax fibers (dissolution) after hydrothermal ageing at 40°C and 60°C. The cell walls are peeling off from the flax yarns. And this phenomenon and observation are very innovative and important for cellulosic fiber undergo hydrothermal ageing. This is also attributed to the water absorption by the cellulosic fibers, which causes delamination of the different layers within the fibers. Moreover, the outer layer can be degraded by the dissolution of pectin, hemicelluloses and some poorly crystallized celluloses of the primary wall. DOI: 10.1002/app.48787
