A plurality of nozzles lined up in the width direction of the fabric are installed on both the front and back sides of the fabric in the fabric transfer path from the upper part of the processing tank filled with a treatment liquid such as chemical soda or hot water to the treatment liquid. Pressure water is sprayed horizontally and slightly downwardly on both sides, and the warp and weft threads of the fabric are untwisted by collision with the jet stream, and the fabric is transported toward the treatment liquid, and the fabric is pulled up from the treatment liquid. The company adopted a configuration in which it was pulled out to the outside of the treatment tank.

Further, in the second invention, a processing tank filled with a processing liquid such as chemical soda or hot water is provided in the transport path of the textile, and a guide roller for guiding the textile into the processing liquid is provided at the upper side of the processing tank. A feed roller is provided at the upper part of the other side of the processing tank to transport the fabric pulled up from the processing liquid to the outside of the processing tank, and on both sides of the transfer path for the fabric from the guide roller to the processing liquid, there is a feed roller for transporting the fabric pulled up from the processing liquid to the outside of the processing tank. We adopted a structure in which a plurality of nozzles that spray pressurized water slightly downward from the horizontal direction are provided at required intervals in the width direction and vertical direction of the fabric.

C Embodiment] Hereinafter, embodiments of the present invention will be described based on the accompanying drawings.

As shown in FIG. 1, the fabric A, which is fed in the direction of the arrow by a pair of upper and lower feed rollers 1, is fed into a treatment liquid such as chemical soda filled in a dipping tank 2, and deposits such as glue and residue are deposited thereon. is removed. The fabric A pulled up from the treatment liquid in the dipping tank 2 is guided to a delivery roller 3 provided at the outlet of the dipping tank 2, and is conveyed downstream by the rotation of the delivery roller 3.

On the downstream side of the dipping tank 2, a first processing tank 4, a second processing tank 5, and a third processing tank 6 are provided in order in the textile transport direction.

The bottom surfaces of the first to third processing tanks 4 to 6 are smoothly curved, and a predetermined amount of processing liquid is filled inside the bottom surfaces. Chemical soda water and hot water are used as the treatment liquid, and are used depending on the type of fabric A. The temperature of the treatment liquid is
The temperature is set appropriately depending on the feed rate and the type of fabric, and when the fabric A made of polyester or rayon is run at about 35 m/min, the temperature is preferably about 90 to 98°C.

A guide roller 7 is provided at a textile inlet portion formed on one side of the upper part of the first processing tank 4, and the washed textile A is guided by the guide roller 7 and introduced into the processing liquid.

Here, the guide roller 7 may be rotated in one direction by a drive device, or may be rotatably supported so as to rotate by contact with the fabric A.

As shown in FIGS. 2 and 3, on both sides of the transfer path from the guide roller 7 to the processing liquid, a large number of nozzles 8a and 8b are installed at required intervals in the width direction and vertical direction of the fabric A. The numerous nozzles 8a provided on the front surface of the fabric A and the nozzles 8b provided on the back surface are shifted by half a pitch in the vertical and horizontal directions.

Each nozzle 8a, 8b is designed to spray a treatment liquid of the same quality as the treatment liquid in the first treatment tank 4 slightly downward from the horizontal direction, and in the embodiment, the jet pressure is about 2 kg/cd, In addition, the temperature of the processing liquid is set to 50°C or higher.

By spraying the treatment liquid from the nozzles 8a and 8b, the treatment liquid hits the fabric A in a horizontally elongated shape as shown by the chain line in FIG. 3, and due to the collision with the treatment liquid, the warp of the fabric A The weft yarn is untwisted and a wrinkle is formed in that area. In this case, if the fabric becomes wavy due to collision with the treatment liquid, the formation of wrinkles will be weakened, so each nozzle 8a, 8
A net-like guide 27 is provided between b and the fabric A to prevent the fabric A from waving.

Further, the fabric A is transported downward due to collision with the treatment liquid sprayed from the nozzles f3a and 8b. Therefore, almost no tension is applied to the fabric A, and the wrinkles are formed without tension, so that round wrinkles can be formed.

The textured fabric A is transferred into a treatment liquid, and the high temperature of the treatment liquid causes the fabric A to relax and the warp and weft yarns to remain untwisted.

At the upper part of the other side of the first treatment tank 4, there is provided a feed roller 10 for meandering correction whose inclination is adjusted by driving the motor 9, and the fabric pulled up from the treatment liquid is guided to the feed roller 10. The rotation of the roller 10 transports it toward the second processing tank 5 .

The position of the nozzle 8b is shifted by half a pitch in the left and right direction.

By arranging the nozzles 13a and 13b as described above, wrinkles are uniformly formed over substantially the entire fabric A.

In the formation of grain in the first treatment tank 4 and the second treatment tank 5, the fabric A is undulated by collision with the treatment liquid sprayed from the nozzle, and the amount of undulation is small in the widthwise center of the fabric A, and on both sides. Since the fabric A is thick at the edges, the wrinkles on both sides of the fabric A tend to be incomplete.

In order to uniformly form wrinkles over the entire fabric A, a third treatment tank 6 is provided.

A guide roller 17 is provided on one side of the upper part of the third processing tank 6 to guide and transport the fabric A sent from the second processing tank 5 downward, and the fabric is sent from the guide roller 17 into the processing liquid.
