<p>Fabric (1) is dried by means of gas fired emitters (6) that can be selectively switched on and off to control the amount the drying. A control system measures the steam evaporating from the fabric surface, the speed of conveyance of the fabric (1) and the surface temperature of the fabric and switches on or off gas fired emitters (6) accordingly to ensure the fabric emerges from the drier at a desired residual moisture content without burning or scorching. A heat setter comprising modulated electric short wave emitters (10) and a pyrometer (11) may be used to heat set the fabric after drying. <IMAGE></p> |
