Water stable fibers and articles made therefrom are formed from a thermoplastic composition comprising destructured starch, polyhydric alcohol, triglyceride, and optionally acid. Processes for making water stable compositions may comprise melt extruding a mixture of destructured starch, polyhydric alcohol, triglyceride, and optionally acid, to form an extrudate, and heating the mixture, extrudate, or both to provide a water stable article.

L'invention concerne des fibres stables à l'eau et des articles fabriqués à base de ces fibres, que l'on obtient d'une composition thermoplastique comprenant de l'amidon destructuré, de l'alcool polyhydrique, un triglycéride, et éventuellement de l'acide. Des processus permettant de fabriquer des compositions stables à l'eau peuvent consister à extruder par fusion un mélange d'amidon destructuré, d'alcool polyhydrique, de triglycéride, et éventuellement d'acide, pour former un extrudat, et à chauffer le mélange, l'extrudat, ou les deux pour produire un article stable à l'eau.
