Method and apparatus for the liquid treatment of a textile fabric

Priority: November 11, 1970 / Japan Filing Nos .: 45-93769 and 45-98770

The invention relates to a method and an apparatus for the liquid treatment of a textile material, in particular for treating a textile fabric of great width and length in a treatment vessel in which the treatment liquid is included.

One of the known methods of treating a fabric with liquid is to use a Conveyor or lifting shaft provided. Here, a take-up roll or shaft is above the surface of the in a treatment vessel contained liquid level arranged. The fabric to be treated is made from the treatment liquid pulled and then the liquid in the longitudinal direction again zig-

leads and immersed in it. When pulling the fabric out of the treatment liquid upwards the liquid adhering to the material flow down in streams on the surfaces of the textile due to gravity. These liquid flows are an important cause of the disturbance of the flawless surfaces of the treated Textile fabric, for example a carpet made of acrylic fibers, especially if the treatment liquid used is on high temperatures. For textiles from the Recently developed synthetic fibers that naturally become soft when exposed to high temperatures, interfere with the high temperature liquid flows on the tops of the fabric during treatment run down, the appearance of the surfaces is quite considerable and cause the pile of the fabric to become tangled and stick together like lumps and / or that the individual fibers are bent over.

Recently, a new dyeing method in which dyeing is carried out at a high speed has been developed. This method involves the use of a jet nozzle and a long, continuous piece of tissue being withdrawn at high speed from the dye bath in which it is immersed. In addition, this process provides for the fabric to circulate in the dyebath, if dyeing is also carried out at high speed with this process, the process has the disadvantage that the fabric is exposed to considerable tension when it is circulated in the treatment plant, which leads to the fact that the finished fabric is undesirably hard and has lost its grip. The process has a further disadvantage because the system required for this is expensive. A method is also known in which the fabrics to be treated are circulated in a vessel containing a treatment liquid. However, a number of difficulties arise in this method _s under andex'ein

that the feed roller from which the fabric is immersed in the treatment liquid is often unsuitable is to feed the long fabric properly and smoothly.

The object of the invention is therefore to create a method and an apparatus which are extremely uniform and reliable fluid treatment, for example Enable dyeing, degumming, heat treating and washing of a long, continuous fabric of great width.

The method and device according to the invention have the advantage that they provide reliable liquid treatment of a textile material of the specified type with a device, its structure as well as the operation and the controls are extremely simple and can be placed in a room with a relatively small floor space Has.

Like from Pig. 3 is evident to 5 - the roll core 5 comprises a hollow shaft 9 with an open lower end. An aligning disk for the liquid flow is firmly centered around the upper area of the same, while a lower aligning disk 11 for the liquid flow is firmly centered around the lowermost end of the V / elle 9. A plurality of upper, arm-like rods 12 are attached to the underside of the upper alignment disk 10 and project radially outward from the outer circumference of the hollow shaft 9. A plurality of lower, arm-like rods are attached to the upper side of the lower alignment disk 11 and point radially outward from the outer circumference of the hollow v / elle 9. These rods 12 and 13 preferably extend outward from the outer circumference of the hollow shaft 9 at uniform, outwardly widening distances between the individual rods. Each of the upper rods 12 and the upper rods 13 is provided with a desired number of anchoring means arranged at a distance from one another *, for example with projections 14 that have hooks 6 * or with bolts and nuts or similar anchoring means that the opposite edge areas in the width direction treated textile material 1, which is wound cylindrically and spirally around the core of the roll, with an appropriate distance between adjacent windings - being maintained »firmly in its position.

Fig. 6 shows in a vertical section the arrangement, in which the cylindrically wound roll 8 of the textile material 1 in the cylindrical treatment vessel 2 with

289822/0822

a liquid is treated. As can be seen from the drawing, is the vessel 2 at the bottom with the connection of a heating pipe 15 and a hollow support part 17 with a puddle 16 provided on which the hollow shaft 9 of the roller core 5 is supported in its position. Outside the treatment vessel 2 is a reversible circulation pump 22 is provided for a treatment liquid, which is connected to lines 18, 19 and 20, 21 is connected, which open in the lower area or in the upper side area of the treatment vessel 2. Within the hollow support part 17 is a rotating body, for example a Rotary vane 24 is provided, which causes the treatment liquid to circulate in the vessel 2 and is suitable due to its driving connections with a motor arranged outside of the vessel 2 to carry out 25 reversible revolutions. On top of a cover 25 of the treatment vessel 2 is a motor 26 for intermittent or continuous rotation of the roll core 5 or alternatively to cause a vertical oscillating movement of the roll core 5 over a Appropriate crank device, not shown here, is provided.

In the device described above, the treatment of the textile according to the invention takes place in the following manner. First, the wide and long fabric 1 is cylindrical and i spirally wound around the axis 7 of the core 5 wherein a convenient distance a "is maintained between adjacent windings while the opposite side edge portions 3 and 4 in the direction of the width b of the iextiistoffs 1 by the Verättkerüngaelemente, for example those on the projection 14 nm roll core 5 in front

Ea, however, is more expedient to create an arrangement 27 by rotatably supporting the roller core 5 in a horizontal position on a shaft

of fabric roll, like Pig. 2 shows. Then, as shown in FIG. 6, the roller 8 is inserted into the treatment vessel 2 introduced that the axis 7 of the fabric roll 8 extends in the vertical direction. Then it becomes a treatment liquid introduced into the vessel 2. Thereafter, the fabric 1 undergoes treatment with the supplied liquid exposed, either the treatment liquid or the fabric roll 8 or, according to an alternative solution, "both be set in rotation. In particular, the otoffrolle 8 are held stationary, while the treatment liquid by means of the pump 22 and the rotating body 24 by the vessel 2 circulates. Or the roll of fabric 8 can rotate either intermittently or continuously or are set in vertical vibrations by the drive from the motor 26. These can also move both types can be combined in an expedient manner.

In connection with FIG. 6, a method is described in which only the treatment liquid circulates, while the roll of fabric 8 is held stationary. The rotation of the rotating body 24 causes the treatment liquid in the cabbage shaft 9 in the direction indicated by the arrow migrates upwards, so that the ascending liquid flow through openings 28 in the upper region of the hollow shaft 9 are provided, from the hollow shaft 9 is discharged. The liquid streams discharged to the outside from the cave shaft 9 flow in the direction indicated by the arrows through the one in the upper disengaging disk 10 for fluid flow provided openings and drain down in the corresponding spaces a / between the adjacent ones Turns of the roll of fabric 8, which is spirally wound. After passing through the cylindrical part of the vessel, these downward flowing liquid flows are caused, through the openings in the lower alignment disk 11

209822/0822 ^ f * ° ° ^m

for the flow of liquid as well as through openings 29 in the lower region of the hollow support part 17, whereby a circulation of the treatment liquid through the entire vessel 2 is achieved. The lines 18 and 19 serve as suction lines and the lines 20 and 21 as supply lines for the treatment liquid. By driving the pump 22 to operate these lines, the treatment liquid is released from the lines 20 and 21, which act as discharge lines, into the upper area of the treatment vessel. These streams of liquid then flow through the openings in the upper alignment disc 10, as indicated by the arrows, and run down through the spaces a between the adjacent projections of the spirally wound fabric 1 to be treated. These separate streams of liquid then flow through the openings in the lower alignment disk 11 for the liquid flow. From there the liquid is sucked into the lines 18 and 19 and then forced to circulate in the vessel 2. The circulation of the treatment liquid caused by the rotating body 24 and the circulation of the liquid caused by the pump 22 can take place either separately or simultaneously. According to an alternative solution, the rotating body 24 and the pump 22 can also be grounded together, offset in rotation in the opposite direction, so that the treatment liquid circulates in a direction which is opposite to the direction indicated by the arrows «

In the embodiment shown in FIG the drive of the rotating body 24 and the pump 22 can also be interrupted. Ss can also depend on the arrangement of the rotating body 24 and the pump 22 can be omitted. In addition, the wound roll 8 can either be intermittent by the motor 26 alone or rotated continuously in the treatment liquid. Or the direction of rotation of the wound roll 8 can periodically reversed and the

rotation in the "two opposite directions" repeated will. Instead, however, the wound roll 8 can also be used in a repetitive manner by means of an expedient device Oscillating movement in the treatment liquid in vertical direction. It goes without saying that these types of movement of the wound roll 8 and the above-mentioned ways of circulating the treatment liquid can be combined in any manner.

If the textile fabric 1 to be treated shown in FIG. 1 is a carpet, it is desirable that the distances a between adjacent turns of the spirally wound healing are approx. 100 mm, the diameter of the roll core 5 3.5 to 4.0 m, · the speed of rotation the rolled up roll 8 to be treated in a liquid as shown in FIG. 6 approx. 5 rpm and the vertical stroke of the oscillating movements of the roller 8 is approx. 100 mm.

It should be noted that the carpets to be treated generally have a width b of up to 5 m. So when the wound roll 8 is inserted into the treatment vessel 2 or from the open top of the cylindrical Treatment vessel 2 is to be taken out, these are Operations are only possible if there is enough space above the vessel to allow it to be inserted and removed unhindered to enable, which consequently requires a very tall building. This inappropriateness can be avoided by that a treatment vessel 2 is used, which can be turned over from its upright position, so that the wound roll 8 of the rotated treatment vessel 2 laterally fed in and removed from the same side can, instead of from the top of the upright vessel »The liquid treatment in the vessel 2 is in an upright position position made, into which the vessel was pivoted back after the lateral insertion of the roller 8.
