To provide the smooth transfer of a fabric by preventing a friction mark or a pressure mark of a fabric and further a pushing wrinkle thereof from occurring especially in a nearly U-turn passage of an inlet part of a retention vessel in a pneumatic type apparatus for treatment at an ultralow bath ratio.

A liquid jetting nozzle 17 for a treating liquid is installed in a nearly U-turn passage 7 in an inlet part of a retention vessel 6 connected to a transfer passage 5 in a pneumatic type apparatus for treatment, comprising the transfer passage 5 connected to the retention vessel 6 and capable of circuiting and treating a fabric 24 with a jetting force of a mixed fluid of a gas stream with a liquid stream jetted from a treating fluid jetting part 12. The treating liquid is jetted in the forward direction of the fabric 24 along the inner vessel to thereby from a water film between the fabric 24 and the inner vessel wall.
