Abstract
Apparatus and method for removing moisture from textile products which are sufficiently porous to permit a substantial flow of heated fluid through the product. Two separate drying regions are provided through which a web of textile product is serially moved. The textile product divides each drying region into a pair of drying zones, and a differential pressure of heated air is maintained on opposite sides of the textile product in each of the heating regions to maintain a flow of heated air through the textile product. The wet textile product first passes through an initial heating region for flowthrough exposure to air heated to a temperature exceeding the temperature at which the dry textile product is damaged, for evaporation of unbound moisture without damaging the textile product. The textile product then passes through a subsequent heating region for flow-through exposure to recirculating air at a temperature which is nondamaging to the textile product. Heated air is withdrawn from the air being recirculated in the second region, further heated, and supplied to the initial or superheat region for more efficient operation.
