AB - The poor crease recovery performance of linen fabrics has resulted in attempts to improve this 
characteristic by modifying the structure of the flax fibres from which the linen is woven. In this 
paper, flax fibers were oxidized with sodium periodate solution leading to a variety of polymers 
having functional groups such as aldehyde group for subsequent modification. Several factors 
(oxidant concentration, pH values, oxidization temperature and time) on the weight loss, 
mechanical properties and content of the formed aldehyde groups were analyzed. Structure and 
morphology of oxidized flax fibers were also investigated. Results show that the characteristic 
absorption band due to aldehyde group strengthened the oxidized fibers. The crystallinity 
decreased and endothermic decomposition temperature dropped gradually with the increase of 
oxidant concentration, oxidation time and temperature, as well as their mechanical properties. 
Moreover, when the fiber was oxidized with high level oxidization degree, the conformation of flax 
completely transferred to a random coil. So as a textile material, the oxidization degree of flax 
should be reasonably controlled.
