2. Description of the Related Art Conventionally, an airflow type processing apparatus and method have been known in which a cloth is transported mainly by an airflow, and the cloth is wetted by a processing liquid so that a dye attached to the cloth is colored and fixed. For example, in Japanese Examined Patent Publication No. 63-36585, hot air or steam is used to start fabric circulation with an air flow by a blower, and then the steam supplied from a supply conduit is used to raise the temperature to a set temperature for a predetermined time circulation treatment. And the applicant of the present application is Japanese Patent Publication No. 7-30
No. 505, a gas-liquid mixed fluid is atomized and supplied,
We have proposed a device that provides a relaxing effect while transporting the fabric without tension while realizing an extremely low bath ratio.

[0003]

However, since these air flow type processing devices have an extremely low bath ratio as compared with the liquid flow processing device, a cloth jam occurs in the retention tank during repeated circulation and the cloth is pushed into the cloth. There was a risk that fire would be generated, or that threads and attrition could occur at the entrance of the retention tank by contacting the inner tank.

The object of the present invention is to eliminate the above-mentioned problems and to improve the slippage of the fabric at the entrance of the retention tank,
Smooth circulation can be realized even for cellulose fibers.
It is intended to improve the quality of fabric processing.

In the fourth aspect of the invention, an air flow type treatment device for a rope-shaped fiber product is provided, which is combined with a liquid jet nozzle for forming a water film and a corrugated plate provided at the sliding bottom of the retention tank.

According to the fifth aspect of the invention, an annular fabric processing passage is provided which connects the transfer passage and the retention tank at both ends, and the fabric loaded in the fabric processing passage mixes the air flow and the liquid flow from the treatment fluid ejecting section. In the air flow type processing method of performing dyeing and other treatments while repeatedly circulating the transfer passage and the retention tank by the jetting force of the treatment fluid, the cloth is introduced into the entrance of the retention tank from the transfer passage. An airflow type treatment method for a rope-shaped fiber product was performed, in which a treatment liquid was sprayed from the upper part in the traveling direction of the cloth along the inner tank to form a water film between the cloth and the inner tank.

(Operation) In the first aspect of the invention, since the liquid injection nozzle is provided above the U-turn passage at the entrance of the retention tank of the cloth processing passage, a water film is formed along the inner tank of the retention tank, and the treatment is performed. The cloth that has been transferred in a substantially straight line in the transfer passage by the jetting force of the fluid jetting unit can prevent the occurrence of threads and attrition without directly contacting the inner tank wall with this water film, and the direction can be smoothly changed. You can convert and downhill. Therefore, there is no possibility that a cloth jam occurs in the retention tank. The treatment liquid supply to the liquid injection nozzle may be branched from the treatment liquid circulation passage or a separate supply passage may be provided.

In the second aspect of the invention, since the liquid injection nozzle is connected to the branch passage from the treatment liquid circulation passage, the design is easy without providing a separate treatment liquid supply passage. In the third aspect of the invention, since the liquid injection nozzle is provided with the opening having a lateral width along the inner tank of the retention tank, the water film is reliably formed. In the fourth aspect of the present invention, by combining the corrugated plate provided at the bottom of the glide bottom in addition to the liquid jet nozzle, a smooth glide can be achieved.

In the fifth aspect of the invention, the treatment liquid is jetted along the inner tank from the upper part of the U-turn passage at the inlet of the retention tank toward the advancing direction of the cloth to form a water film. The inner tank of the retention tank can be separated from the inner tank, and the fabric does not directly contact the wall surface of the inner tank, prevents the occurrence of threads and atari, and enables smooth transfer to the bottom of the glide. It was
