Once plastic strain has occurred and created a fold, the rock layers will remain folded even if the strain is removed. This is because the deformation has resulted in permanent changes to the structure of the rocks, causing them to remain in their folded configuration. While the fold may slowly undergo additional deformation through time, it will not simply bounce back to its original shape.
