The main long time to keep in solution, because paper can greatly raskisnut and tear when they remove it.

And specifically how long to keep that paper does not limp? I understand that it depends on many factors: variety, content of wood pulp, age, and keeping the original quality of paper production, so it is difficult to give an exact answer, but at least an order of magnitude? And can we somehow move the process to determine that the paper is about raskisnet, and urgently need to remove it from the solution?
