(54) | Method and apparatus for drying a textile fabric |
(57) 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. |
