Drying Without Warping: Airflow, Sheet Thickness and Time to Safe Moisture for Handmade Paper Dried on Racks
Year: 2026
Type: article
Abstract: This paper addresses a practical question in sheet thickness: handmade paper leaves the press still holding most of its weight in water. Using a self-contained computation from stated assumptions, the study evaluates the options across the range a small operation ordinarily meets and identifies the point at which the balance of cost, quality and material use changes. The headline findings are that hours 2mm still air is 15.6; hours 2mm fan 1ms is 5.9; hours 4mm still air is 31.2; hours 2mm rh80 is 18; hours 2mm rh40 is 6. These figures come from a simulation study: the work is SIMULATED, NOT MEASURED, no physical trials were performed, and every number reported is taken from the deposited computation output so that any reader can reproduce or refute it with local values. The practical value of the result is a rule that can be applied at the point of work without further calculation, together with the tabulated cases from which the rule was derived and a statement of the assumptions on which it depends. Where the computation shows that a widely used practice wastes money or material, that finding is stated directly; where it shows that a popular economy is genuine, the size of the genuine saving is stated with equal directness, so that effort can be directed to the economies that are worth having.
