Abstract
A method for preserving hides, skins and pelts prior to tanning, without salt-curing. The hides are fatliquored, pickled and dried, all prior to tanning. The method may include the preliminary steps of washing, fleshing, liming and unhairing followed by the steps of fatliquoring, deliming, bating, pickling and drying. The method avoids the environmental damage caused by salt-curing. The treated hides are dry, flexible and readily rehydrated for further processing.
