Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a continuous treatment process for fabric in which a treatment liquid is impregnated into a fabric that moves continuously, and after a predetermined length of fabric is impregnated with a predetermined liquid, the next predetermined length of fabric is impregnated with a predetermined liquid. When fabric is impregnated with different specified liquids in the same liquid tank, automatic liquid exchange of fabric processing liquid allows the quality of liquid in the liquid tank to be automatically changed as a specified length of fabric passes through. It is about the method.

When industrially produced long fabrics are dyed continuously, for example, the color may be changed every certain length of the long fabric, or a different process such as resin processing may be performed after the dyeing process. In many cases, it is required to perform these tasks continuously.

Specifically, when dyeing a long fabric, for example, it is often required to dye each predetermined length a different color. In the conventional case of performing such different color dyeing, each time the dye solution in the tank is changed, the running of the fabric in the tank and the steamer used for dyeing is interrupted, or the supply of moist heat in the steamer is interrupted. After washing the inside of the liquid tank and replacing with new dye liquid,
Since the running of the fabric is continued again, when the running of the fabric is interrupted and restarted, a change in humidity and heat occurs in the steamer, which makes it impossible to uniformly dye the entire surface of the long fabric. There was a problem that made it possible. In addition, there was also the problem that productivity was reduced due to the interruption of fabric running and the need to wait for restart.

The present invention has been made in view of the above circumstances, and provides an automatic liquid exchange method for fabric treatment liquid that can automatically and effectively exchange the liquid in a treatment liquid tank without interrupting the running of the fabric. The purpose is to

Further, to describe the present invention more specifically, a guiding cloth is connected between the end of a long cloth of a predetermined length to be continuously processed and the starting end of the next long cloth,
A mark is provided at an appropriate position on the guide cloth or at the joint between the guide cloth and the treated fabric, and the passing of this mark is detected and the cleaning and liquid exchange in the liquid tank filled with the treatment liquid to be impregnated into the treated fabric are performed. We have developed an automatic liquid exchange method for fabric treatment liquid that can automatically perform this process, and by this method, a predetermined length of fabric can be processed without interrupting the transfer of the fabric to be treated with liquid. Different types of processing liquids can be applied and impregnated continuously in each case, which has the effect of significantly improving productivity.

The present invention will be explained in detail below based on embodiments shown in the drawings.

First, to describe the continuous liquid processing apparatus for fabric in detail, reference numeral 1 denotes an outer wall of the continuous liquid processing apparatus that continuously transports the fabric 2 to be impregnated with liquid. Guide rolls 3 ₁ , 3 ₂ , 3 ₃ for guiding in a substantially V-shape and a pair of squeeze rolls 4 ₁ , 4 ₂ arranged above the guide rolls 3 ₃ are provided. Further, between the guide rolls 3 ₁ and 3 ₂ and between 3 ₂ and 3 ₃ , there is a pair of left and right passage frames 5 forming a liquid passage 9 which also serves as a transfer path for the fabric 2 transferred in a V-shape. are arranged in an inverted eight-shape, and the inner edges of the lower ends of both passage frames 5 are in watertight contact with the guide rolls ₃₂ . Reference numeral 6 denotes a movable frame spaced apart from the lower side of the guide roll ₃₂ , and this movable frame 6 is opened and closed using a support shaft 8 as a fulcrum by the operation of a cylinder 7. When the movable frame 6 is closed, the upper surface of the movable frame 6 is pressed against the lower end side edge of the passage frame 5 in a watertight manner. Therefore, a substantially V-shaped liquid passage 9 is formed by the guide roll 3 ₂ , the opposing passage frame 5, and the movable frame 6. In this embodiment, a substantially V-shaped liquid passage 9 is formed. The total length of the liquid passage 9 was designed to be 500 mm, and the width a of the liquid passage 9 was designed to be 3 mm, but the total length of the passage 9 was experimentally determined to be 400 mm ~
It is desirable that the passage width be 1000 mm and the passage width be 2 mm to 5 mm. 10 is a processing liquid supply pipe for supplying the processing liquid into the liquid passage 9, and 11 is a cleaning liquid shower disposed at a suitable position in the outer wall ₁ . ,3
₃ , the squeezing rolls 4 ₁ , 4 ₂ , the surfaces of the movable frame 6, etc. are disposed in large numbers at positions where they can be effectively cleaned. 12 is a foam extinguishing board, 13 is a cleaning liquid tank,
14 ₁ , 14 ₂ , 14 ₃ are different processing liquid tanks,
15 indicates a pre-dryer using infrared rays.

The structure of the continuous liquid processing apparatus has been described above, and the following guiding cloth 22 of a predetermined length is connected to the terminal end of the cloth ₂ through the guiding cloth ₂₁ shown by the two-dot chain line.
is placed on top. In addition, the cloth 2 and the guiding cloth 2 ₁
For example, a colored mark 18 in a different color is applied to the seam 17. 19 is the colored mark 18
This mark sensor 19 is a sensor for detecting the mark sensor 19, and is disposed at an appropriate position in the fabric transport path. Reference numeral 20 denotes an electronic control circuit, which inputs a mark detection signal from the mark sensor 19 and controls the electromagnetic valves 21 ₁ , 21 ₂ , _{21 3} , 21 ₄ , 21 ₅ of each liquid tank at a predetermined timing. ,
The drive motor 22, cylinder 7, etc. can be selectively operated.

Next, to explain its effect, cylinder 7
When the piston is projected, the movable frame 6 moves to the position shown by the solid line, and the lower outer edge of the passage frame 5 is brought into close contact with the upper surface of the movable frame 6, thereby creating a substantially V-shaped liquid passage 9. It is formed. Therefore, the fabric 2 is made to run through this liquid passage 9, and the processing liquid supply pipe 1
By sequentially supplying the treatment liquid in an amount that can be absorbed by the fabric 2 from 0 to the liquid passage 9, the fabric 2 traveling in the liquid passage 9 is impregnated with the treatment liquid. By sequentially supplying fresh processing liquid into the liquid passage 9 from the processing liquid supply pipe 10 so that the liquid in the liquid passage 9 does not run out, the fabric 2 is always impregnated with fresh processing liquid and the impregnation process is completed. I can continue.

The liquid treatment of the fabric 2 thus transferred progresses,
When the end of the fabric 2 approaches the liquid treatment device,
When the mark 18 provided near the joint between the end of the fabric 2 and the guiding fabric ₂₁ reaches the position of the mark sensor 19, the detection output of the mark sensor 19 is introduced into the control circuit 20, and thereby the motor 22 is decelerated and the speed of fabric 2 is decelerated.
The terminal end of is immersed into the liquid passage 9. A signal from the roller control circuit 20 whose terminal end is drawn out from the liquid passage 9 causes the liquid to be supplied from the processing liquid supply pipe 10 to the solenoid valve 2.
1 ₁ or 21 ₂ or 21 ₃ , the infrared dryer 15 is stopped, and the cylinder 7 is further operated to open the movable frame as shown by the chain line. Next, the solenoid valve ₂₁₅ or ₂₁₄ opens, and the cleaning liquid in the cleaning liquid tank 13 is sprayed from the processing liquid supply pipe 10 and the cleaning liquid shower 11, and the cleaning water is sprayed onto the movable frame 6, the fabric guide rolls ₃₁ , ₃₂ , 3 ₃ ,
It is sprayed onto the surfaces of the passage frame 5, squeezing rolls 4 ₁ , 4 _{2 ,} etc., for effective cleaning in a short period of time. During this cleaning operation, the transfer of the fabric, that is, the transfer of the guide cloth, continues, and the guide cloth ₂₁ continues to wash and wipe the peripheral surface of each roll. When cleaning of the liquid processing device is completed and the guiding cloth ₂₁ passes through the liquid processing device, the movable frame 6 is closed by a signal from the control circuit 20, and the liquid passage 9 is formed again. 9, a preset new processing liquid is supplied from the processing liquid supply pipe 10, and the motor 22 rotates normally, so that all operations are restored as explained by our office. The liquid impregnation treatment on the fabric ₂₂ is performed continuously.

As described above, the present invention connects a guiding cloth between the end of a long fabric of a predetermined length to be continuously processed and the starting end of the next long fabric, and connects the guiding cloth to an appropriate position. Alternatively, a mark may be placed at the joint between the guide cloth and the treated cloth, and when the passing of this mark is detected, the processing liquid to be impregnated into the treated cloth is outputted from an operating control circuit without stopping the running of the cloth. This is an automatic liquid exchange method for fabric processing liquid, which is characterized by automatically sequentially performing drainage liquid cleaning and liquid exchange in a filled liquid tank device. As the process progresses, the liquid in the liquid treatment tank is automatically replaced, resulting in labor savings. Further, according to the present invention, the liquid in the liquid tank can be quickly replaced (about 2 minutes) without interrupting the progress of the fabric or the subsequent wet heat treatment equipment, etc., so that productivity can be improved.
