[0002]

2. Description of the Related Art As is well known, a cloth (woven fabric) after weaving.
For the purpose of removing various contaminants contained in the cloth, it is refined with a refining liquid such as caustic soda. Further, since the woven fabric is stretched and is in a tense state and has poor elasticity and flexibility, it is preferable to loosen the tense state, so-called relax and shrink. When refining the fabric,
The warp and weft that make up the fabric absorb the refining liquid and swell, and the fabric shrinks, but this alone may not sufficiently shrink depending on the conditions such as the material, and another treatment is required. was there. Conventionally, the process is a batch type, not a continuous type, in which several pieces of cloth that have been cut into a certain length are collected and placed in a smelting solution, and the smelting solution is swirled to make the cloth swim in the smelting solution. It was a thing. Although this method can shrink the cloth at a high shrinkage rate, it takes a very long time and an improvement has been desired.

Of pipes that extend in the width direction, and holes are provided at intervals in the length direction. High-temperature steam having a pressure of 1 to 3 kg / cm ² is supplied from one end of the pipe, and the steam is ejected from the holes. The steam spraying means 24 is provided above and below the belt 26, and steam is jetted downward from the steam supply means 24 above and sprayed onto the fabric 4 on the belt 26. Steam is jetted upward from the spraying means 24, and the steam passes through the mesh of the belt 26 and is sprayed onto the cloth 4 on the belt 26.

In the present invention, the pressure imparting means 20 for vibrating the continuous cloth 4 in the refining liquid storage tank 3 against the second conveyor 5B of the continuous cloth conveying means 5. And a cloth refining means 6 including a refining solution discharging means 7 for discharging the refining solution toward the continuous cloth 4 in the refining solution storage tank 3.

The cloth refining means 6 is provided above the refining liquid storage tank 3 and is provided with a plurality of pressing imparting means 20 which are swung so as to press the cloth 4 in the refining liquid storage tank 3.
The cloth 4 in the refining liquid storage tank 3 is kneaded and washed with the refining liquid by the pressing application means 20. The refining liquid discharging means 7 is provided between the pressing applying means 20 and is connected to a pump (not shown), and the refining liquid in the refining liquid storage tank 3 is supplied to the refining liquid discharging means 7 by the pump to perform refining. The refined liquid from the liquid discharge means 7 is the cloth 4 in the refined liquid storage tank 3.
It is designed to be released toward. A heater 21 is provided in the refining liquid storage tank 3 so that the refining liquid can be heated to raise the temperature.

A beater 3 is provided above the refining liquid storage tank 3.
2, 33 are provided. This beater 32 is for folding the cloth 4 before entering the refining liquid storage tank 3 in a fold shape, and has two bar members 35 that rotate around the central axis, and the bar member 35. By hitting the cloth 4, the cloth 4 can be folded in a fold shape. When the cloth 4 enters the refining liquid storage tank 3, the cloth 4 becomes pleated with a short pitch as shown in FIG. The cloth 4 pulled up from the submersible conveyor 17 often remains in a double-layered state, and the beater 33 is for beating and loosening the cloth 4 in such a state. A bar member 37 is provided, and the bar member 37 taps the cloth 4 to eliminate the double stack.

Next, in the cloth shrinking apparatus 1 described above,
A case where the cloth 4 is conveyed via the first conveying path 18 shown in FIG. 3 will be described. First, the continuous cloth 4 is guided by each of the plurality of conveying rollers 13 and the guide rollers 14, is carried into the steam chamber 2 through the inlet 9, and is conveyed toward the cloth relaxing means 8. When the cloth 4 reaches the conveyor 22, the rod-shaped member 27 and the belt 26 vibrate due to the driving of the vibration generator 28, and the cloth 4 on the belt 26 vibrates. The vibration of the cloth 4 facilitates the movement of the warp threads and the weft threads constituting the cloth 4 with respect to the threads intersecting the threads.

Further, high-temperature steam is sprayed onto the cloth 4 on the belt 26 from the steam spraying means 24 arranged above and below the belt 26, and the warp and weft are heated and become soft. Therefore, the tense state of the warp and the weft can be relaxed very effectively. Cloth 4
After passing through the fabric relaxing means 8, the bar is undulated by the bar member 35 of the beater 32, becomes pleated when entering the refining liquid, and is conveyed by the underwater conveyor 15.

Then, the refining liquid is discharged from the refining liquid discharging means 7, and the pressing means 20 swings up and down to press the cloth 4, and the cloth 4 is kneaded and washed with the refining liquid. As a result, impurities contained in the cloth 4 are removed, and the cloth 4 is refined. Further, the cloth 4 is kneaded and washed to further alleviate the tension. The cloth 4 discharged from the refining liquid storage tank 3 is beaten and unraveled by the bar member 37 of the beater 33, conveyed by the conveying roller 13 and the guide roller 14, and conveyed out of the steam chamber 2 through the outlet 10.

When the cloth 4 is relaxed, the cloth 4 contracts, the cloth 4 becomes bulky and the flexibility is improved, and the touch feeling becomes good. Further, the stretchability of the fabric 4 is improved,
Secondary products such as clothes made of this cloth do not easily shrink even when washed. As a result of the experiment, the weight is 100 to 150 g /
When the m ² fabric is vibrated at 5500 to 6000 Hz,
It has been found that favorable results are obtained.

When the cloth 4 is only processed by the cloth relaxing means 8 and is not refined, the cloth 4 may be conveyed by the second conveying path 19 shown in FIG.

Further, in the above embodiment, the cloth shrinking device 1
In the above, the fabric 4 is treated by the fabric relaxing means 8 and then refined by the refining liquid, but it may be refined by the refining liquid first and then treated by the fabric relaxing means 8. FIG. 5 shows an example of the fabric shrinking device 1 configured as described above.

Further, as shown in FIG.
May be inclined such that the transport surface becomes lower as it advances in the traveling direction. In this way, the conveyor 22
Since the upper cloth 4 easily vibrates, the shrinkage rate of the cloth 4 becomes higher. The inclination angle of the conveyor 22 may be adjusted according to the material and weight of the cloth 4.

Further, as shown in FIG. 7, a plurality of cloth relaxing means 8 may be provided.

[0027]

As described above, when the cloth shrinking device of the present invention is used, the cloth can be shrunk at a high shrinkage rate regardless of various conditions such as the material, and the cloth becomes bulky and flexible. It improves the texture, so the texture becomes much better. Therefore, it is possible to give the cloth a sense of quality and increase the commercial value of the cloth. Also, since it is not a batch type but a continuous type, the fabric is processed at high speed, automation, labor saving,
It is possible to achieve the intended task by saving energy.
