Saturated steam‐assisted radio frequency fixation of reactive printed cotton fabrics

The aim of this study was the development of a prototype machine for the processing of fabrics, which can be used as a reactor for the continuous finishing processes. The optimum applicator design for fabrics was developed in accordance with laboratory-scale experimental studies. Reactive printed samples were treated with the combination of radio frequency and steam in order to take advantage of the steam energy and to improve energy absorption. The colour yields of the samples fixated with the combination of radio frequency and steam energy were compared with conventional steaming (10 min) and thermofixation (5 min) processes. It was observed that steam-assisted radio frequency fixation ensured similar colour yields in a shorter setting time (3 min) compared with conventional methods. It was concluded that the new system could be an alternative method of setting, with the advantages of time savings and lower energy consumption.
