Abstract
A process and apparatus for the shrinkage of prepared bonded fiber color printed cellulosic type currency where in the process the prepared bonded fiber color printed cellulosic type currency is substantially free (known as oven dry and/or bone dry) before starting the procedure, then is immersed in anhydrous ammonia solution at low temperature, withdrawn and dried by different techniques. The process of immersing and drying is repeated 1 to 8 times. The apparatus to accomplish this provides for a closed loop and/or stainless steel rack and/or stainless steel tong with a thermally controlled vessel. All apparatus to be immersed and all apparatus to be used to contain the anhydrous ammonia solution should be made from a non-corrosive material (i.e. stainless steel and/or glass) to anhydrous ammonia. The color printing to the shrunken prepared bonded fiber color printed cellulosic type currency is not removed.
