To provide a continuous steam setter capable of preventing the generation of a pale dyed stripe unevenness caused by continuous steam set, and further to obtain processed goods hardly having the pale dyed stripe unevenness generated by the continuous steam setter.

This continuous steam setter has a steam zone and a compressed air zone. A saturated steam with a high pressure is circulated in the steam zone, and the steam zone has gateways of the processed goods at the both ends. The compressed air zone is installed at both ends of the steam zone, and maintained at the pressure higher than the saturated steam pressure. A superheated steam zone is not substantially formed at the entrance side boundary part of the compressed air zone and the steam zone.
