WebApr 10, 2024 · Recently, the relaxation behaviors of regenerated cellulose fibers induced by water have been studied. These explorations suggest that the glass transition temperatures of 513–552 K in a dry state are shifted to room temperature by interaction with water. This water-induced behavior may also occur in the transitions of natural cellulose fiber.
