Description

DETAILED DESCRIPTION OF THE INVENTION A. OBJECTS OF THE INVENTION A-1. Field of Industrial Application The present invention relates to batch processing such as scouring and dyeing of thin fabrics.

A-2 Prior Art The treated fabric was made into an endless type and was circulated and treated using the treatment liquid jetting force and the rotational force of a reel.

A-3 Problems to be Solved by the Present Invention In the conventional processing apparatus described above, when processing thin fabrics, turbulent flow of the processing liquid tends to occur at the downstream end of the transfer pipe, which disrupts the alignment of the fabrics and prevents smooth circulation. It had the drawbacks of frequent sludge, low productivity, high bath ratio, and high running costs.

B Structure of the Invention B-1 Means for Solving the Problems The present invention aims to eliminate the above-mentioned drawbacks and provide an apparatus that can significantly improve productivity. The outlet part is formed into a slope shape extending above the level of the accumulated liquid, a rotating reel is arranged at the upper end, and the processing liquid is guided vertically downward to the installation part of the rotating reel through a processing liquid injection nozzle. However, the lower end on the inlet side is bent and extended almost horizontally, and the bottom part is sloped so that the cross-sectional area of the retained liquid part gradually increases from the inlet part of the retention tank to the U-turn part. .

Row 2 Effect: The treated fabric is transported from the upstream end of the transfer pipe to the inlet of the retention tank via the inclined pipe 2b, and the fabric speed is gradually reduced and braking is not applied abruptly, so the fabric is transported without turbulence. The alignment is stabilized, which eliminates kinks, and the retention tank is tilted to collect the processing liquid at the U-turn, allowing for a low bath ratio, allowing for efficient processing such as scouring and dyeing.

RO-3 Embodiment Next, an embodiment of the present invention will be described based on the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a retention tank which has a U-shape when viewed from above, and has an inlet 5 and an outlet 4 at both ends of which the treated fabric is transferred. Reference numeral 2 denotes a pipe for transporting fabric etc. in a straight state, and a treatment liquid spray nozzle 3 is provided at the upstream end. Retention tank 1
At the outlet part 4 of the tank, there is a tapered pipe 7 extending upwardly beyond the level 6 of the processing liquid accumulated in the tank at an inclination angle of 20 to 35.
A rotary reel 8 is arranged at the upper end of the tapered pipe 7, and the inlet side 2a of the transfer pipe 2 is led out vertically downward from the installation part of the reel through the processing liquid injection nozzle 3. ing. The transfer pipe 2 is
The lower end of the inlet side 2' communicates with the inlet portion 5 of the retention tank via a horizontal conduit 2b which is bent and extended in a substantially horizontal manner. The retention tank 1 is inclined so that the U-turn part 1' is the lowest part, and the inlet part 5 and the outlet part 4 gradually rise from this part. In the drawing, reference numerals 9 and 10 indicate a liquid draining section made of a perforated plate provided in the retention tank 1, 11 a rectifier pipe, 12 and 13 a suction pipe, 14 a pump, 15 a heat exchanger, and 16 a processing liquid injection nozzle 3. 17 and 18 are flow rate control valves, 19 is a liquid sending pipe, 20 is a drain valve, 21 is a water supply valve, and 23 is a flow rate control valve. Reference numeral 22 denotes a reverse injection device, which is normally used to return the treated fabric when it becomes entangled with the rotating reel 8.

Note that T is an endlessly connected fabric, which is transferred to the outlet part 4 side in a meandering manner while being accumulated in the retention tank 1, and is pulled up the tapered tube 7 by the reel 8, and this pulling force and the treatment liquid injection are The liquid is sent into the transfer pipe 2 by the liquid flow injected from the nozzle 3, and is aligned in the inlet part 5 of the retention tank 1 without getting entangled, so that the inclined part of the tapered pipe 7 can be pulled up again from the outlet part 4 of the retention tank 1. It is constructed so that it repeats rotation.

C. Effect of the invention As mentioned above, the speed of the fabric is gradually decelerated through the inclined pipe line 2b of the transfer pipe and braking is not applied suddenly, so the fabric is smoothly aligned and introduced into the retention tank without causing turbulence. This eliminates the loosening of thin fabrics, which has been difficult to treat in the past, and since the processing liquid is collected in the U-turn section of the retention tank, it is possible to reduce the bath ratio and perform processing such as scouring and dyeing efficiently. be able to.
