Description

Detailed Description of the Invention A00 Purpose of the Invention E1. Industrial Application Field The present invention gives a physical kneading effect to the fabric to relax and
This invention relates to a wet heat treatment device that continuously performs treatments such as scouring.

E2. Prior Art Conventionally, as for this type of device, as seen in Japanese Patent Publication No. 44-18399, there has been an invention in which a fabric held between frames is rapidly moved in and out of the processing liquid, and an impact is applied to the liquid surface, A method of moving and applying a treatment liquid to the fabric (Japanese Patent Publication No. 11148/1983, Japanese Patent Publication No. 11475/1973) is known.

E30 Problems to be Solved by the Present Invention In all of the conventional processing devices described above, it is inevitable that tension is applied during processing, and although a large amount of mechanical energy is spent, there is little fir effect on the fabric. It has the drawbacks of limited processing speed, low productivity, and low productivity.

0 Structure of the Invention 10 Means for Solving the Problems The present invention eliminates the above-mentioned drawbacks and provides an apparatus that enables uniform and good relaxing and scouring treatment of fabrics and further improves productivity significantly. In this system, the treated fabric is transferred in a wide width state through a fabric transfer path formed below the liquid surface by the gap between the net conveyors installed vertically. A transfer passage is formed, and a pair of injection nozzles are arranged oppositely on the upper and lower sides of the fabric transferred in a wide width state across the fabric transfer passage. The present invention is characterized in that a plurality of sets are provided, and the upper injection nozzle and lower injection nozzle of each set are alternately and intermittently operated.

Row 22 action: By alternately spraying the treatment liquid toward the fabric from the upper and lower spray nozzles, the wide fabric in the fabric transfer passage is transferred to the net below by the spraying force of the upper spray nozzle. Push up to the conveyor, then stop the injection,
Next, by intermittently pushing the fabric up to the net conveyor above using the spray force of the lower spray nozzle, it is possible to apply an impact force to the fabric and to impart a large deformation motion to the fabric.

Furthermore, by transporting the fabric to the downstream end in an orderly manner using the upper and lower net conveyors, the fabric is intermittently subjected to impact force and deformation motion at the injection nozzle position while moving through the fabric transfer path, and the effect of the injection nozzle is reduced. There is no tension at the position where it is not exposed, and this process is repeated intermittently until it is sent to the downstream end, and the fir effect is assisted in a short time and efficiently, resulting in moist heat treatment such as relaxation and scouring that is good and highly productive. can be done.

Row 3. Example Next, the present invention will be described in detail based on the accompanying drawings.

FIG. 1 is a schematic side sectional view of the wide fabric relaxing treatment apparatus of the present invention. (1) is a wet heat treatment tank for fabrics having a fabric inlet and an outlet, (3) is the treatment liquid level, (2) and (
2°) is a net conveyor, which is endless, and the speeds of the upper net conveyor (2) and the lower net conveyor (2°) can be set arbitrarily. (5)
(6) is an upper side injection nozzle, and (6) is a lower side injection nozzle, and a large number of sets are arranged vertically facing each other along the moving direction of the fabric.

Then, the upper injection nozzle (5) and the lower injection nozzle (6
) can be injected alternately and intermittently, and can be set in the range of 30 to 200 times per minute. First, the treated fabric (4) is transferred to the lower net conveyor (
2゛), then stop the injection,
Next, the injection force from the lower injection nozzle (6) pushes the treated fabric (4) up to the upper net conveyor (2), then stops the injection, and the upper injection nozzle (5) and the lower injection nozzle (6) ) are operated alternately and repeatedly, so that impact force and rapid deformation motion can be applied at high speed to the treated fabric (4) in a short period of time. The most effective direction of application of the jetting force is in a range where it is inclined at 15 degrees from the vertical direction toward the downstream end.

The upper injection nozzle (5) and the lower injection nozzle (6) exchange heat with the pump (11) with respect to the suction port (9) provided at the bottom of the wet heat treatment tank (1) for the fabric near the downstream end of the fabric. vessel(
12) and a filter (13) to form a processing liquid circulation path.

(7) is a flow direction switching mechanism that can alternately repeat the actions of the upper injection nozzle (5) and the lower injection nozzle (6). By arranging the lower horizontal part of the lower net conveyor (2゛) to move below the bottom of the wet heat treatment tank (1) for fabrics, the amount of treatment liquid can be significantly reduced, and the treatment liquid level ( 3) is the upper injection nozzle (5
), and by alternating injection, the injection flow rate can be halved and the pump capacity can be reduced, allowing for significant savings in mechanical energy and a more compact device configuration. The cascade device (14) is a circulation pipe aΦ
The outlet of the cascade device (14) is led to the upstream end of the fabric transfer passageway (8), and the outlet of the cascade device (14) is connected to the upstream end of the fabric transfer passageway (8), and the inlet roll (18
) plays the role of smoothly guiding the treated fabric introduced into the pipe. (20) is a steam valve, and (21) is a steam wrap. A fabric accumulation amount adjusting mechanism (17) is provided at the downstream end, and the fabric accumulation amount is adjusted appropriately and is pulled out by an exit roll (19).

In this way, the impact, floating, and deformation motion of the fabric due to the pressing and washing caused by the alternating upward and downward jetting force can be applied by sequentially moving the point of action at high speed as the fabric moves from the upstream end to the downstream end, and can be applied in a short time. Moist heat treatment such as relaxation and scouring can be performed uniformly in a short amount of time.

C.9 Effects of the Invention As described above, the present invention solves the problems of conventional devices of this type, improves quality through effective fiddling action, and significantly increases productivity by increasing processing speed. be able to.
