Wood-based cellulose fibers, which are widely utilized, are gaining attention as one of the materials driving resource recycling. The defibration process is essential for recycling in resource circulation, but much remains unknown about the changes in cellulose fibers during this process. This is because cellulose is a crystalline polymer material with a complex hierarchical structure, and there are limited means to investigate the changes in this complex hierarchical structure during the defibration process.
Kato et al. (Thu,) studied this question.
