Résumé

The objective of this work is to link structure and processing conditions to the fibrillation of Lyocell fibers. Two main types of Lyocell fibers were studied, standard with various processing conditions and crosslinked. Standard fibers have a skin-core structure with a more amorphous skin of 35-80 nm. Crosslinked fibers are resisting much more to fibrillation in the wet state. The crosslinked layer is thicker that the skin. The diameter distribution of fibrils is very wide and ranges from a few tens of nanometers to several micrometers. It depends on the type of fiber and its processing conditions. The higher the wet abrasion resistance is, the larger the number of fibrils is and the finer their diameter is.
