Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a continuous washing device after printing and coloring of silk cloth and cotton knit cloth.

[Prior Art] The printing of industrially produced long fabrics involves the printing process in which the dye is attached (printing) to the pretreated fabric, and the sizing agent attached to the surface of the printed fabric is removed. The desizing / cleaning step and the dyeing step in which the dye on the desalted cloth surface is fixed to the cloth are distinguished. The present invention relates to a desizing apparatus installed in the desizing / cleaning step. . That is, the conventionally known desizing / cleaning device of this type arranges a large number of desizing tanks in the cloth transfer direction, and disposes a large number of guide rolls in these desizing tanks.
Desizing is performed by repeatedly acting (contacting) a cleaning liquid (water) on the cloth transferred by these guide rolls.

[Problems to be Solved by the Invention] However, in the conventional desizing and cleaning apparatus, since the cleaning effect is low, the same cleaning apparatus performs repeated cleaning several times. Next, there was a problem that the white spot was contaminated due to the migration of the dye at the time of staying during the next washing. Further, in the conventional cleaning device, since the cloth to be cleaned is simply a cleaning means that expects cleaning by passing through the cleaning liquid tank, it takes a long time to complete desizing. Along with this, the overall equipment length of the cleaning device also becomes longer,
There is a problem in that the equipment is large in size and the equipment cost is high. There are cases where the print cloth is silk cloth and cotton knit, but when the cloth is silk cloth and cotton knit, strong tension is applied at the time of transfer due to the characteristics of the silk cloth or the sizing agent is dropped. However, there is a restriction that a strong impact force cannot be applied and the temperature of the cleaning hot liquid cannot be raised to, for example, 50 ° C. or more. In the case of cotton knit, it is necessary to enhance the cleaning effect, and therefore the hot liquid temperature is, for example, 100
Since it is required that the temperature is close to ℃, it cannot be used for the treatment of silk cloth and cotton cloth with one type of cleaning equipment, and for this reason, the desizing cleaning for silk cloth treatment and cotton cloth treatment is performed. There was also a problem that the device had to be installed.

[Means for Solving the Problem] The present invention has been made in view of such conventional problems, and a first object thereof is to use one type of glue regardless of whether the print cloth is silk cloth or cotton cloth. By enabling the common use of the de-cleaning device, de-sizing and cleaning can be effectively performed without deteriorating the quality of each cloth even if it is either silk cloth or cotton cloth. It is to reduce if possible.

Secondly, in order to enhance the effect of removing the sizing agent adhering to the surface of the cloth, the means for applying the cleaning liquid (water) acting on the cloth is improved so that even a small-scale cleaning device is effective. Desizing and washing can be performed, thereby preventing the white spot contamination of the printing and coloring fabric, and not only reducing the equipment cost, but also providing a cleaning device with a high cleaning effect that can achieve labor saving. is there.

The above is the configuration of the present embodiment. Next, the operation thereof will be described. When the cloth 1 to be cleaned to which the printing paste is attached is transferred, the cloth 1 is first dipped in the water-containing tank 24 to be formed. The entire surface gets wet. Next, the cloth is guided by the perforated drum 21 and transferred, and then transferred to the next step through the guide roller 23 on the outlet side. In the left guide portion guided by the perforated drum 21, the shower box 26 is provided. Transferred against the flow of fresh water flowing down from ₁ . That is, since the fresh water flowing down from the shower box 26 ₁ is sent into the narrow gap (a), it becomes a high water pressure flow, and the cloth transferred against the water flow has an effective cleaning force. Moreover, the permeation amount of the running cloth to the inner core of the cloth is increased by the action of the perforated drum 21 in the cloth transferred while receiving the water pressure flow, which further enhances the cleaning efficiency of the cloth and the removal of the sizing agent is effective. Become. The fabric that has passed the apex of the perforated drum 21 has a gap (a) on the right side.
A perfect cleaning can be expected by receiving the stream of reused water sent inside. The cloth washed in the white-field contamination prevention cleaning tank 2 in this manner is introduced into the next pre-washing tank 3 without transfer of dye and accompanying white-field contamination. The cloth 1 supplied to the pre-wash tank 3 is the washing liquid tank 31.
The cleaning water that is guided and transported by the plurality of perforated drums 32 arranged inside and is overflowed from the shower box 36 is applied toward the fabric 1 guided by the perforated drum 32. The washing water overflowed from the shower box is film-like effluent (shower water) 315 having a running water width along the width direction of the cloth to be transferred as described above. That is, uniform washing water without any interruption is applied, whereby uniform washing water flows down over the entire surface of the fabric, and as a result, good washing without uneven washing can be expected. Further, the wash water that has flowed down from the shower box 36 and is applied to the cloth 1 has a large number of through holes 33 formed in the perforated drum 32 that guides the cloth, so that the passing amount to the cloth 1 is promoted. That is, the permeability of the cleaning liquid to the inner core of the cloth is enhanced, and as a result, the cloth is effectively cleaned under water-saving resources. Further, in the present embodiment, the cleaning water to be applied to the cloth is a means for applying water by gravity flow, for example, compared to a conventional applying means for applying a strong jet pressure water jetted from a nozzle. It is also characterized in that it is possible to obtain a good wash-treated cloth which does not easily cause the fabric such as a knitted fabric to be loosened or bent and which does not impair the quality.

The thus pre-washed fabric is sufficiently swollen while being nipped and transferred by the pair of upper and lower net conveyors 42 in a tensionless state, and is supplied to the next washing tank 5. For example, in the case of cleaning such as discharge printing, the neutralizing agent cleaning by the cleaning tank 5 receives the same cleaning action as that of the pre-cleaning tank 3 to neutralize the acid applied to the cloth. After the finishing washing by the washing tank 6 by the same washing action, the cloth 1 is washed with washing water of about 30 ° C. in the case of silk, or with washing water of about 60 ° C. in the case of cotton. The series of cleaning process is completed.

In the above cleaning device, the rubber curved expander 8
An expander device 10 having a scroll expander 9 and a scroll expander 9 is arranged at various places, and at the time of processing a silk cloth, a rubber curved expander projects to a cloth transfer path to guide the expansion of the silk cloth, and at the time of processing a knit, the scroll expander makes the cloth expander. Since the knitted fabric is projected on the transfer path to spread the knitted fabric, and the earring prevention guide is performed, this continuous cloth treating device can be commonly used for treating silk fabric and knitted fabric.

[Advantages of the Invention] As described above, the present invention provides a perforated drum that continuously guides and conveys the cloth to be washed in the conveying direction.
And a white-field pollution prevention cleaning tank 2 having a laminar flow plate facing the cloth in contact with the perforated drum with a gap therebetween, and a shower box for feeding cleaning water toward the gap, and on the peripheral surface. A rotary drum having a large number of through holes, and a washing liquid flow-down tank that naturally flows down toward a cloth guided and guided by the rotary drum and forms a continuous film-like flowing water over the entire length in the width direction of the cloth. The pre-washing tank 3 and the swelling washing tank 4 in which a pair of upper and lower endless conveyors for sequentially nipping and transferring the shaken-off fabric in a non-tensioned state are provided in the moist heat reaction chamber, a washing tank 5, a finishing washing tank 6 and a low temperature. A rubber curved expander, a scroll expander, and a rubber curved expander, which are arranged in parallel in the transporting path of the cloth, which are arranged in order of the washing tank 7. Since this is a cloth cleaning device provided with an expander device having drive means for moving the positions of the scroll and the scroll expander into and out of the cloth transfer path, the shower box in the white-field contamination prevention cleaning tank 2 is particularly suitable. The washing water flowing down from the tank is sent into a narrow gap formed between the tank flow plate and the cloth and the perforated drum to have a high water pressure flow. Therefore, the cloth to be cleaned is subjected to this high water pressure flow, so that the surface of the cloth is Of course, effective white field contamination prevention cleaning can be expected over the inner core of the cloth, and in the pre-wash tank 3, the cleaning liquid that acts on the cloth is a natural falling liquid, so an unreasonable external force acts on the cloth. It is possible to eliminate problems such as leaning and bending of the eyes. Further, since the flow-down liquid acting on the cloth is formed into a film and applied to the entire width of the cloth, uniform cleaning can be expected over the entire width of the cloth. Furthermore, since the drum that guides the cloth has liquid permeability,
Since the passage of the cleaning liquid to the inner core of the fabric is promoted, and in the swollen swab cleaning tank, the swollen swab cleaning tank for transferring the fabric without tension is effective. As compared with the conventional cleaning apparatus, the desizing cleaning of the cloth is performed in an extremely short time, and the cleaning apparatus excellent in cost efficiency and productivity can be provided.

Further, since the expander device is arranged at an appropriate place on the cloth transfer path, the cleaning device can be shared by the expander device at the time of silk cloth treatment and knitting treatment, so that equipment cost, heat energy, water resources, etc. It is possible to save processing cost and achieve economical processing, and it is also possible to spread and transfer suitable for silk cloth and knitted cloth, and achieve good quality processing without damaging those cloths. The effect is obtained.
