Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention is directed to removing impurities, such as glue, attached to the surface of a long fabric such as a woven fabric or a knitted fabric by reducing the amount of water used and the thermal energy used. This invention relates to a continuous cleaning device for fabrics that has been developed to be able to effectively wash off the fabric while saving energy and resources.

[Background of the Invention] Immediately after the printing process of industrially produced long textiles, the printing paste attached to the surface of the processed fabric or the backing layer attached to the back side of the fabric is used. A cleaning process is required to remove impurities such as glue. A conventional cleaning device used in this cleaning process includes, for example, a cleaning tank 21 filled with and supplied with cleaning water (dry water) 20, as shown in FIG.
(hereinafter referred to as a conventional type), the fabric 23 to be washed after the printing process is guided by the guide rolls and immersed in the liquid. Since the cleaning method relies on a simple method of contact with cleaning water that involves repeated immersion in water, the cleaning efficiency in multiple tanks is low, and therefore it is necessary to install multiple cleaning tanks in advance, It is inevitable that a large amount of fresh water will be consumed as it is necessary to sequentially supply a large amount of fresh water to the washing tank.For example, the amount of fresh water used for washing after printing 1 kg of fabric (cotton fabric) is approximately 2.57 ON/H was consumed.

In addition, as a water-saving type cleaning device that is an improvement over the conventional type, for example, as shown in FIG. A chamber 25, a guide roll 2 disposed within the rigid chamber 25 for transporting the fabric 26 to be washed in a meandering manner from below to upward, and a guide roller 2 disposed within the liquid tank 24 for transporting the fabric 26 to be washed in a meandering manner.
Guide roll 28 that transports 6 in a meandering manner in the liquid.
There is also a cleaning device that has a water supply pipe 29 for showering cleaning water from the ceiling of the vertical room 25 toward the fabric 26.

In this water-saving type, the amount of clean water for cleaning treatment per 1 kg is approximately 1. However, even with these cleaning devices, the intended cleaning could not be achieved unless a large amount of clean water was consumed. However, due to the current shortage of water resources, efforts are being made to save washing water when washing fabrics or to reduce the equipment costs of washing equipment. Moreover, the equipment cost increases due to the installation of multiple cleaning tanks, so a large amount of equipment cost and a large amount of water resources are consumed as usual.

[Object of the Invention] The present invention has been made in view of the above, and is a method for continuously washing a fabric by applying washing water to the fabric after printing, which is continuously run. In order to reduce the amount of water consumed and to perform cleaning effectively in a short period of time, cleaning water is applied to the fabric introduced into the cleaning chamber to remove the rope and impurities attached to the fabric. The fabric is swollen and the swollen rope material and impurities are forcibly removed by brushing, thereby effectively cleaning the fabric after printing while saving water resources. The purpose is to provide a continuous cleaning device.

[Embodiments of the Invention] The present invention will be described in detail below based on embodiments shown in the drawings.

Reference numeral 1 indicates a fabric to be cleaned (hereinafter referred to as fabric), and this fabric 1 has a printing paste adhered to its front surface and a grounding paste adhered to its back surface.

Reference numeral 2 denotes a washing tank for cleaning the rope material of the fabric 1, and inside the washing tank 2 and above the washing tank 2, there are guide rolls 3 for making the fabric 1 meander in the vertical direction. are arranged. 4 is a shower nozzle for spraying washing water toward the front and back sides of the fabric 1 that is transported in a meandering manner by these guide rolls 3, and these nozzles 4 are arranged at positions close to each guide roll 3. ing. Reference numeral 5 denotes a brush roll that comes into contact with the front and back surfaces of the fabric 10 after receiving the washing water from the nozzle 4 to brush the front and back surfaces of the fabric 1, and 6 indicates approximately the middle of the fabric meandering in the vertical direction. The touch bar is a touch bar that can be contacted at a point to prevent the fabric from curling or wrinkling.F is a self-circulation pump for injecting the cleaning water accumulated inside the washing tank 2 from the nozzle 4. , 8 is washing tank 2
This figure shows a pump for supplying (countercurrent) a portion of the water inside the tank to the washing device provided at the front stage.

9 is a supply pipe for aqueous liquid supplied from the next stage water washing device; 11
is a turbidity sensor that detects the turbidity of water in the liquid tank 1 based on conductivity, and if this turbidity is detected to be above a predetermined value, a certain amount of clean water is poured into the washing tank 2. It is supplied from a supply pipe 13. 12 indicates a filter.

The above is the configuration of this embodiment. Next, to describe its operation, the fabric 1, which has printing paste adhered to the front surface and grounding paste adhered to the back surface, is guided by the guide roll 3. While meandering in the vertical direction, the cloth is repeatedly sprayed with cleaning water from the nozzle 4, thereby inflating the shelf material attached to the front and back of the cloth. - The thus expanded shelf material is brushed with the brush 5,
The cloth is forcibly dropped from the surface of the cloth, and then the cloth is cleaned by receiving the force of spraying purified water from the nozzle 4 again.

As described above, in this embodiment, the fabric 1 is able to prevent shelf materials attached to the front and back surfaces of the fabric from falling off due to the synergistic effect of the impact force and swelling resistance caused by the spraying of washing water and the brushing. This has the advantage that it can be done quickly and reliably. Furthermore, in this cleaning device, the cleaning water is self-circulated and reused repeatedly, and only when the cleaning water becomes extremely polluted, the turbidity sensor works to supply a certain amount of clean water. As a result of measuring the amount of water used by the cleaning device according to this example under the same conditions as the conventional and water-saving types, the amount of water used was approximately 0.37 ON/H.
As a result, the amount of fresh water used can be significantly reduced, and the shelf material of printed fabrics can be cleaned effectively while saving water resources.

Furthermore, in this embodiment, since the height difference of the fabric that causes the fabric to meander up and down is set to approximately 2 m or more, the washing water sprayed from the upper nozzle 4 and applied to the fabric is
Since the contact timing with the fabric flowing down can be lengthened, the cleaning effect can also be improved by this.

[Summary of the Invention] As described above, the present invention transports fabric in an up-and-down meandering manner using a large number of guide rolls arranged inside and outside the washing tank, and repeatedly removes the fabric from the liquid. In a cleaning device that alternately transfers water from air to liquid, the cleaning device includes a group of nozzles that spray cleaning water onto both sides of the fabric that is being conveyed in a meandering manner, and respective brush rolls that brush both sides of the fabric. , a self-circulation circuit for injecting water in the washing tank from the nozzle group; and a self-circulation circuit for detecting the degree of contamination of the water in the washing tank, and supplying clean water to the self-circulation circuit if the degree of contamination is equal to or higher than a standard value. This is a continuous fabric washing device characterized by having a contamination level sensor for adding water and a fresh water supply control means.

Therefore, according to the continuous fabric cleaning apparatus of the present invention, the fabric 1 is prevented from falling off by shelving materials attached to the front and back sides of the fabric due to the synergistic effect of the impact force and swelling property of the spraying of the washing water and the brushing. This has the advantage that it can be done quickly and reliably.

Furthermore, in this cleaning device, the cleaning water is self-circulated and reused repeatedly, and only when the cleaning water becomes extremely polluted, the turbidity sensor works to supply a certain amount of clean water. As a result of measuring the amount of water used by the cleaning device according to this example under the same conditions as the conventional and water-saving types, the amount of water used was approximately 0.3TO.
N/H, and the amount of fresh water used was significantly reduced, resulting in the effect that shelf material cleaning of printed fabrics could be carried out effectively while conserving water resources.
