Abstract

The present invention relates to a thermal treatment apparatus (1) suitable for use in the thermal treatment of a body of matter (5) containing a liquid component. The apparatus (1) comprises a pressure chamber (2) having a support means (4) for supporting the body of matter (5) in a R.F. Heating zone (27) inside the pressure chamber (2) in use of the apparatus (1). Output means such as capacitor plate means (25), of a radio frequency heating device (3), are disposed inside the pressure chamber (2) in proximity to the R.F. Heating zone (27) for heating the body of matter (5) supported in said R.F. Heating zone (27). The pressure chamber (2) has a compressed gas supply means (10) for increasing the ambient pressure inside the pressure chamber above atmospheric pressure, whereby in use of the apparatus (1), the body of matter (5) may be heated up to a temperature above the normal boiling point of the liquid component substantially without vaporisation of the liquid component. The apparatus is particularly suitable for use in the thermal activation of textile treatments. <IMAGE>
