    • PURPOSE:To permit the drying and moisture-conditioning of the whole of fibrous products uniformly with reduced energy by a method wherein the moisture content of the fibrous product, coming out of hot-air drying process and before being introduced into high-frequency moisture-conditioning process, is detected and a hot-air temperature and/or the flow rate of the hot-air is regulated based on the detected result of the moisture content. CONSTITUTION:The moisture content of a sliver F after preliminary drying is detected by a moisture content sensor 9 immediately after coming out of a hot-air dryer 1 while the temperature of hot air in the hot-air dryer 1 is controlled by the feedback of the detected result. This control is effected by regulating the opening degree of a steam amount regulating valve 7 provided in a steam supplying pipeline 8 and, therefore, the supplying amount of heated steam, supplied into the steam supplying pipeline 8, is regulated and the heated steam is supplied into a hot-air dryer 1 from a heat exchanger 5 through a circulating pipeline 6. The sliver F, dried preliminary to a moisture content slightly higher than an objective moisture content by a hot-air dryer 1, in which the temperature of the hot-air is maintained in the optimum moisture centent in accordance with the fluctuation of the moisture content of a fibrous product in such a manner, is supplied subsequently to high-frequency moisture- conditioning process and internal heating as well as selecting heating may be effected by a high-frequency dryer 2.
