Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is applicable to
It is possible to process fabrics that are subject to severe liquid processing conditions (for example, fabrics made of silk, linen, or rayon (including mixed-woven fabrics and mixed-knitted fabrics)) that are likely to occur efficiently and with high quality. This invention relates to a spreading liquid flow processing device.

(Background of the Invention and Prior Art) For example, when silk fabrics such as silk fabrics and knitted fabrics are subjected to scouring treatment or dyeing treatment, silk fabrics have the characteristics of high-class fabrics that value luster and feel. However, since this fabric has low friction fastness and is susceptible to damage such as scratches, folds, and wrinkles, care must be taken when handling it during scouring and dyeing treatments. Must take due care.

The following are the main conditions required when performing scouring, dyeing, etc. on silk material cloth. In other words, in order to prevent the occurrence of flaws such as ``frays'', ``bent'', ``wrinkles'', and ``collapse of the texture'', the fabric should not become roped, tangled, or tangled.

Do not put too much tension on the cloth.

As a liquid flow process, for example, a dyeing process, which can be adapted to such processing conditions, conventionally, a hanging process (1:
It is said that it is safe to carry out the process under a high bath ratio of about 100, and other methods such as
As shown in Fig. 8, the fabric to be treated is placed in an endless manner in a circulation treatment system including a treatment liquid tank a for storing the treatment liquid and a guide path b for transporting the fabric to be treated together with the treatment liquid, and the liquid flow is carried out by jet dyeing. The staining method using staining device c was considered to be unsuitable. This is because, when dyeing is performed using such a conventional liquid jet dyeing device, the fabric d to be treated becomes roped, tangled, or tangled during circulation, resulting in scratches, folds, etc. This is because, in addition to the problems that occur easily, there is also the problem that "scratches" occur due to slips that occur between the cloth pulling reel e and the processed cloth d. In addition, since the fabric pulling reel e was arranged so as to be located well above the processing liquid level, the fabric to be processed was forcibly stretched under a large tension and was not shaken horizontally. It was scheduled to be lifted up. As a result, there were problems such as folds, scratches, deformation of the grain, and the like, which impairs the texture and feel of the dyed fabric.

Regarding tension release when pulling up fabric, a method has been proposed in which the fabric is pulled up by placing the fabric on a net-like conveyor that circulates around it driven by a chain drive device, but this method causes sagging on the conveying surface. Therefore, it was unavoidable that the conveying surface would wave due to the influence of vibrations during driving of the chain drive device. However, if silk material fabric is pulled up using such a net-like conveyor, the waving of the conveying surface causes the cloth and the conveying surface to repeatedly come into contact and not come into contact, resulting in "sliding". ” may occur.

(Problem to be Solved by the Invention) However, when dyeing is carried out using the above-mentioned high bath ratio line dyeing, a large amount of chemicals such as dyes and auxiliaries are required because the bath ratio is too high. In addition, there were problems in terms of economy, such as the need for a large amount of heat, and the hanging fabrics came into contact with each other, causing "scratches".
The work must be carried out carefully to avoid such occurrences, resulting in very poor work efficiency and low productivity. In addition, in the string dyeing method, although some processing liquid convection occurs as the suspended cloth moves up and down, the processing liquid itself remains in a stagnant state, which affects the texture and texture of the resulting dyed cloth. I've reached my limit.

In particular, when the fabric is a knitted fabric, the knitted fabric that is hung on a pole tends to stretch due to its own weight, especially the upper part, so the stretched part must be cut off and removed as a defective product. There was also the problem of poor yields.

The present inventor has discovered that "scratches" and "bentness" of silk materials, etc.
In view of these problems with fabrics that are prone to wrinkles, we aimed to develop a liquid flow processing method and device that can efficiently produce high-quality processed products without scratches or folds. , conducted extensive research.
As a result, it was found that in order to satisfy the processing conditions described above, it was necessary to improve the conventional liquid flow processing method and apparatus, mainly taking into account the points described in the following (a) and (b).

(a) The cloth installed in the circulation treatment system must be constantly circulated in an expanded state.

(b) Provide a means for pulling up the cloth so that almost no tension is applied to the cloth being pulled up from the liquid in the processing liquid tank.

The present invention was completed by further developing this knowledge.

(Means for Solving the Problems) In order to solve the above problems, the present invention employs the following configuration.

A spreading liquid flow treatment apparatus (hereinafter referred to as the apparatus) 1 according to the present invention includes a treatment liquid tank 3 for causing a cloth to be treated 2 to swim in the treatment liquid; a cloth transfer guideway 5 disposed in the front-rear direction so as to be inclined downward;
A reservoir extending in the left-right direction so as to be continuous with the upstream end of the guide path 5 and storing the processing liquid 7 sucked out from the bottom of the processing liquid tank 3 by the liquid feeding pump P and heated to a required temperature by the heat exchanger 26 as appropriate. A circulation treatment system is provided, which includes a liquid tank 22; and a non-tension conveyance device 6 for pulling up the cloth 2 to be treated from inside the liquid at the front end of the treatment liquid tank; The cloth to be treated 2 is spread out in an endless manner.
This is a device that performs liquid flow treatment on.

The left and right width L2 of the guideway 5 is set to be substantially equal over the entire length of the guideway, and
The lateral width L1 of the inner surface of the processing liquid tank 3 is set to be approximately equal to the lateral width L2 of the guide path 5 over the entire front and rear length of the processing liquid tank.

Further, the notension conveying device 6 is connected to the liquid storage tank 2.
2, and a fabric feeding reel 27 arranged to extend in the left-right direction on the upper side of the processing liquid tank 3;
A cloth feed reel 27 is disposed between a guide roller 30 and a guide roller 30 disposed so as to extend in the left-right direction parallel to the axis of the cloth feed reel 27.
A conveyance roller 3 extending in the left-right direction parallel to the axis of
1 are arranged in parallel, and the conveyance roller 31, the cloth feed reel 27, and the guide roller 30 form a conveyance surface 6a that slopes upward toward the front, and the cloth feed reel 27, Guide roller 3
0. All of the conveying rollers 31 are driven to rotate at peripheral speeds that do not cause slips between the conveyed cloth 2 and the cloth 2 to be conveyed.
is characterized in that its intermediate portion is supported by parallel conveyance rollers, so that it is conveyed with almost no tension applied.

Note that the apparatus according to the present invention can be applied regardless of whether it is under high pressure liquid flow processing conditions or under normal pressure liquid flow processing conditions.

(Function) Next, based on the above configuration, the device 1 according to the present invention
Explain the effect of

First, the processing liquid tank 3 (the bath ratio is, for example, 1:20~
1:25), the transport device 6, and the guideway 5, after setting the treated cloth 2, which has a width slightly larger than the left-right width L2 of the guideway 5, in a spread state in an endless manner, the liquid feeding pump P is activated and the notification conveyance device 6 is activated. As a result, the processing liquid tank 3
The processing liquid sucked from is heated to a predetermined temperature by a heat exchanger 26 as appropriate and is sent to the liquid storage tank 22. When the liquid level exceeds the upstream end 21 of the guide path 5, the liquid storage tank 22 is heated. The treatment liquid 7 sequentially overflows into the guide path 5, and the cloth 2 to be treated is pulled up from the liquid in the treatment liquid tank 3 by the transport device 6 and dropped into the upstream end 21 of the guide path 5. Accompanied by the liquid flow that tends to spread laterally, the liquid is transferred through the guiding path 5 while maintaining its spread state, and after being introduced into the processing liquid tank 3, it is directed forward in the processing liquid and kept in its spread state. She is forced to move to swimming.

To supplement this explanation, since the width of the cloth 2 to be treated is formed to be slightly larger than the horizontal width of the guideway 5, as shown in FIG.
The paper is transported with its both side edges 2a, 2a guided by both side parts 5a, 5a of the guideway 5 in a stable spread state without lateral wobbling. In addition, the transferred treated cloth 2
Since both side edges 2a, 2a of are protected by the processing liquid, both side edges 2a, 2a are
a, 2a are not in direct contact with the side parts 5a, 5a of the taxiway 5 (for example, there is a gap of about 10 mm between the side edge 2a and the side part 5a of the taxiway 5). (cloth transfer), therefore, there is no risk of "scratching" occurring on the both side edges 2a, 2a. The treated cloth 2 discharged from the guide path 5 is transferred to the rear curved surface portion 9 of the treatment liquid tank 3.
It is introduced into the processing liquid 7 at the upper part and swims forward in the processing liquid 7 in a zigzag shape. Since L1 is set substantially equal, the cloth 2 to be treated is introduced from the guide path 5 into the treatment liquid tank 3 while maintaining the expanded state.
Both side edges 2a, 2a are connected to both sides 1 of the processing liquid tank 3 in the same manner as in the case of the guide path 5.
It swims forward in the processing liquid tank while being guided by the membranes 2 and 12 in its spread state. Then, the cloth 2 to be treated that has reached the front end of the treatment liquid tank 3 is transferred to the conveying surface 6a formed by the notension conveying device 6.
(The lower end of the conveying surface 6a is in a state close to the processing liquid surface 29).
in a state in which the cloth to be processed 2 is supported by the rollers and reels, and in a state in which no slip occurs between the cloth to be processed 2 and each roller and reel.
It is pulled up from the liquid and transported in its spread state.
Therefore, the tension applied to the cloth to be treated 2 during conveyance is distributed over the entire cloth to be treated 2A that is being conveyed in an expanded manner. Therefore, the tension in a portion of the fabric to be transported becomes very small, and the fabric to be processed 2 is pulled up from the liquid and transported in a state close to that of no tension. By repeating the above-described cycle, the desired treated product of good quality can be obtained.

(Example) Examples of the present invention will be described below based on the drawings.

1 to 5, the device 1 according to the present invention includes:
a treatment liquid tank 3 for swimming the cloth 2 to be treated from the rear to the front in the treatment liquid; a guide path 5 for transporting the cloth disposed in the front-rear direction above the treatment liquid tank 3; A no-tension conveyance device 6 that pulls up the treated cloth 2 from inside the liquid at the front end of the treatment liquid tank.
The apparatus is equipped with a circulation treatment system consisting of; and; the cloth 2 to be treated is placed in the circulation treatment system in an endless manner in a spread state, and the cloth 2 to be treated is subjected to a liquid flow treatment.

A concrete explanation of this is as follows.

That is, the processing liquid tank 3 has a boat shape with the entire upper surface open, and a required amount of processing liquid 7 is accommodated therein. The lateral width L1 of the inner surface of the processing liquid tank 3 is set to be equal over the entire front and rear length (the lateral width L1 of the inner surface is set approximately equal to the lateral width L2 of the guiding path 5, which will be described later), and The side bottom portion 9 and the front bottom portion 10 are curved portions extending upward, and the front bottom portion 10 in particular has a large number of through holes 1 for draining liquid.
1 (in the figure, the diameter is exaggerated to be larger than the actual diameter) is a perforated curved surface portion. In this embodiment, approximately the front half 12 of the opposing sides 12, 12 of the processing liquid tank 3
a, 12a (the part surrounded by the dashed line in Fig. 4), there is a through hole 13 for draining the liquid (the diameter is exaggerated in the figure to be larger than the actual one) so as to cover almost the entire surface of the part below the liquid level. ) are drilled in large numbers. Further, in FIGS. 1 to 4, the reference numeral 14 is formed by surrounding the entire front bottom portion (perforated curved surface portion) 10 and approximately the front half portions 12a, 12a of both sides of the processing liquid tank 3 with a surrounding wall 15 at a required interval. This is a jacket for sucking out the treated processing liquid.

The guide path 5 is disposed above the processing liquid tank 3 in the front-rear direction so as to be inclined downward toward the rear. The bottom surface 16 of the guideway 5 is smooth, and its left and right width L2 is set equal over the entire front and rear length, and the overall shape is shaped like a flat gutter or tube (in the figure, it is shaped like a gutter). Ai is shown). In this embodiment, a required number of through holes 19 for discharging the processing liquid for dripping and discharging the processing liquid flowing down the guideway 5 are provided on both sides 17, 17 of the downstream end portion of the guideway bottom part 16. It is perforated. Also, the downstream end 2 of the guideway 5
0 is made so as to face the upper part of the rear curved surface part (rear side bottom part) 9 of the processing liquid tank 3 (see FIG. 4),
The upstream end 21 opens upward in a liquid storage tank 22 for storing the processing liquid, which is arranged to extend in the left-right direction at the slightly upper front side of the processing liquid tank 3 . The liquid storage tank 22 is connected to a jacket liquid drain part 2 at the bottom of the processing liquid tank by a liquid guide pipe 23 (see FIG. 4).
The processing liquid from the liquid extraction part 25 which is sucked out by driving the liquid feeding pump P is heated to a predetermined temperature by a heat exchanger 26 and then supplied to the liquid storage tank 22 . In addition, the jacket liquid drain part 25
is in communication with the through hole 11 for draining liquid in the front bottom part 10 of the processing liquid tank and the through hole 13 for draining liquid in the side part 12 of the processing liquid tank (see FIG. 3).

The notension conveyance device 6 includes a liquid storage tank 22.
A cloth feed reel 27 is arranged to extend in the left-right direction slightly above the processing liquid tank 3, and a cloth feed reel 27 is arranged parallel to the axis of the cloth feed reel 27 slightly above the processing liquid level 29 (see FIG. 4) at the front end of the processing liquid tank 3. The required number of transport rollers 31 (in the drawings, 8
(a case in which books are arranged side by side is shown), the conveyance roller 31, the cloth feed reel 27, and the guide roller 30
The conveying surface 6 is inclined upwardly toward the rear.
The cloth feed reel 27, the guide roller 30, and each conveyance roller 3 are arranged in parallel so that a is formed.
1 is rotated by an appropriate driving means at a circumferential speed that does not cause slippage between the cloth 2 to be treated and the cloth 2 to be conveyed.
By supporting the middle portion of the paper by parallel conveyance rollers, the paper is pulled up and conveyed with almost no tension applied. In addition,
When conveying the cloth to be treated 2, in order to make the contact between the cloth to be treated 2 and each conveyance roller 31 even more sufficient, each conveyance surface 6a is slightly curved upward. It is preferable to arrange the rollers 31 in parallel in an arched manner. Note that the guide roller 30 can be attached and detached in one-touch so that an entrance and exit for the person can be formed at the lower end of the notension conveyance device 6 in case a person enters the processing liquid tank 3 during maintenance and inspection. It is better to do so.

The function of the device 1 according to this embodiment is the same as that described in the "function section" above.

In the apparatus according to the present invention, partitions are provided in the liquid storage tank 17, the guide path 5, and the treatment liquid tank 3 over the entire length of the cloth to be treated 2 in the circulation direction, and the circulation treatment system is divided into multiple rows. There is also. In addition, when dividing the circulation treatment system in the case where holes 13 for draining the liquid are provided in the side part 12 of the treatment liquid tank, in order to obtain an effect of preventing ripples by draining the liquid from the side part 12 in each division, It is assumed that the circulation processing system is divided into two sections. At this time, taking the partition in the processing liquid tank 3 as an example, the partition 32 is formed with side plates 33, 33 separated by a required interval, as shown in FIG. A through hole 35 for draining liquid is drilled over almost the entire area under the surface,
It is preferable that the open lower ends 36 of the side plates 33, 33 are opened into the jacket 14. When formed in this manner, the processing liquid is sucked out from both sides of each section 37, 37, and undulating of the processing liquid within each section can be prevented as much as possible. In addition, when a partition is provided in the guide path 5, it is preferable to provide a through hole for discharging the processing liquid in each section as described above.

Further, FIG. 7 shows a case in which the notension conveying device 6 is constituted by a guide roller 30, a conveying roller 31, and a roller-like cloth feed reel 27, all of which have the same diameter, and the cloth contacting portion 3 of the adjacent rollers
The distance L3 between 9 and 39 is set equal.

(Effects of the Invention) According to the apparatus of the present invention, (a) the cloth to be treated can be safely transferred in a stable spreading state in the guideway without the risk of "scratching", and (b) the cloth to be treated can be safely transferred to the treatment liquid tank. After being introduced into
The fabric to be treated swims in the processing liquid in a stable spread state, and (c) the notension transport device stably pulls up the processed fabric in the spread state without horizontal wobbling (the lower end of the transport surface is at the level of the processing liquid). After being pulled up in this manner, it is transported in an expanded state without slipping and in a state close to the state of notension.

Therefore, there is no risk that the fabric to be treated will be damaged such as "scratches" or "bent" while being transferred through the guideway or treatment liquid tank, and will not suffer any damage such as "scratches" or "bent" caused by the tension when pulling up the fabric. There is no risk of folding, fabric collapse, etc., and the fabric is constantly circulated in a stable spread state, allowing liquid flow treatments such as scouring, dyeing, and water washing to be performed satisfactorily.

As a result of this, even if the fabric is subjected to severe liquid flow processing conditions (for example, woven or knitted fabrics made of silk, linen, or rayon), it is likely that scratches, folds, or wrinkles will occur. It is possible to perform liquid flow processing with high efficiency and high quality.

Also, to explain the economical efficiency of the present invention, taking the dyeing treatment of silk material cloth as an example, the present invention can be used at a considerably lower bath ratio than in the case of the conventional hang dyeing method described above. (For example, the bath ratio is about 1:100 in the hang dyeing method, and about 1:20 to 1:25 according to the present invention), which saves on chemicals such as dyes and auxiliaries. It can also be expected to reduce energy consumption.
