Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid supply device for fabric that is effectively used in a high-pressure steamer in which fabric is thermally treated under high pressure and heat for pretreatment or dyeing.

For example, the conventional method for pre-treating or dyeing industrially produced fabrics is to pass the fabric to be dyed through a dyeing solution tank, apply dye, and then heat-treat it in a steamer at 100°C or less, that is, in a batch. The color developed intermittently.

Therefore, in conventional dyeing methods, it is not possible to carry out continuous dyeing processing, which results in wasted thermal energy, and the degree of dyeing varies from batch to batch.Moreover, in dyeing methods that use heat below 100°C, the dye is absorbed into the fabric. It was uneconomical because it took a long time to dye.

Therefore, the present inventors conducted long-term research in order to shorten the dyeing time and realize high-speed dyeing, and as a result,
We have developed a high-pressure steamer that can dye or pre-process fabrics continuously in seconds, and are currently in operation. A pair of seal rolls are provided that are pressed against each other in order to continuously feed the fabric into the steamer case.Since the fabric must be fed into the steamer case through this pressurized seal roll, for example, the fabric cannot be fed outside the steamer case. The fabric impregnated with the treatment liquid is squeezed out by the seal roll, resulting in an insufficient amount of liquid impregnated.

Therefore, many methods and devices have been proposed in which a liquid tank is provided inside the steamer housing and the fabric supplied inside the steamer housing is impregnated with a predetermined liquid, but the present invention is based on further research. The present invention provides a liquid supply device for use in

That is, the first purpose of the present invention is to supply a liquid at a constant concentration into a liquid supply tank disposed in a high-pressure steamer to ensure uniform treatment of fabrics.

The second purpose is to reduce waste of liquid by reducing the amount of remaining liquid discharged when replacing the liquid supplied in the liquid supply tank.

The present invention will be described in detail below based on examples (dying examples) shown in the drawings.

1 is a steamer case, 2□ is a fabric inlet formed in the steamer case 1, 2□ is a fabric outlet, and the fabric inlet 2□ and the fabric outlet 2□ are provided with packing for strain absorption. 3 to the inlet side seal mechanism 4 and the outlet side seal mechanism 5.
is installed.

These sealing mechanisms 4 and 5 are provided to allow the introduction and extraction of the fabric while maintaining the high humidity and heat inside the steamer housing 1.The introduction side sealing mechanism 4 has a pair of sealing mechanisms that are pressed against each other. It has seal rubber rolls 4□, and a passage 4□ with a substantially J-shaped side surface provided on the side of the inlet 2 from these seal rubber rolls 4□.

Similarly to the introduction side seal mechanism, the other outlet side sealing mechanism includes a pair of seal rubber rolls 5□ that are pressed against each other, a slow cooling liquid tank 5° whose side surface is approximately J-shaped, and a slow cooling liquid tank 5° inside the slow cooling liquid tank. A liquid supply pipe 53 for supplying a slow cooling liquid that also serves as cleaning from the outside of the steamer, and a slow cooling liquid tank 5□ from this liquid supply pipe 53.
A guide wall 5 for allowing the liquid to flow into the slow cooling tank 5□ after first contacting the seal rubber roll 5 and cooling the seal rubber roll 5 at the temperature of the liquid.
4.

Reference numeral 6 denotes fabric guide rolls arranged vertically in a staggered manner within the steamer housing 1, and a tension adjusting roll 6' is included in the sagging guide rolls.

Reference numeral 7 denotes a liquid tank in which the guide roll 6 is installed, and as shown in FIG. A liquid supply pipe 11 is arranged above the fabric soaking liquid part 9.

Further, an outlet pipe 12 for guiding the liquid to the outside of the steamer housing 1 is connected to the bottom of the overflow part 10, and this outlet pipe 12 communicates with a liquid tank 14 having a stock solution supply pipe 13.

The liquid prepared in the liquid tank 14 so as to always have a constant concentration is supplied into the fabric immersion liquid section 9 from the liquid supply pipe 11 via a pump 15 and a flow meter 16.

Reference numeral 17 denotes a baffle plate provided near the partition wall 8 of the fabric immersion liquid section 9, and this baffle plate 17 is provided to prevent a short path of the liquid.

18 is a drain pipe provided at the bottom of the fabric immersion section 9, 19 is a squeezing lever, 20 is a fabric, and 21 is a liquid level gauge.

Next, to describe its function, since the gist of the present invention is a liquid supply device installed in a high-pressure steamer that performs moist heat treatment of fabrics using high-pressure heat and heat, we will not discuss the function of the liquid supply device in detail. Specifically, the liquid supplied from the stock solution supply pipe 13 in the liquid tank 14 and mixed to a predetermined concentration is pumped by the pump 15 to the fabric immersion liquid part 9 in the steamer case.
supplied within.

The liquid put into the fabric immersion liquid part 9 is impregnated into the fabric 20 guided by the guide roll 6, but the liquid overflowed from the fabric immersion liquid part 9 is absorbed into the overflow part 1.
0, the liquid is recycled into the liquid tank 14 outside the steamer housing 1, and once again has a predetermined concentration, it is supplied into the fabric immersion liquid section 9 again.

The feature of this embodiment is that a liquid of a constant concentration is always supplied into the fabric immersion liquid section 9, so that the fabric can be uniformly treated with the liquid.

Furthermore, a baffle plate 17 is provided in the fabric soaking liquid section 9 to prevent the fresh liquid that is successively supplied from immediately overflowing and to allow the fresh liquid to act on the fabric. A distant relative is the application of a highly efficient fabric liquid that acts on the fabric.

Furthermore, the feature of this embodiment is that the liquid is sequentially supplied into the fabric immersion part 9 to reduce the amount of liquid stored in the fabric immersion part 9, so that there is no need to drain the liquid when replacing the liquid. The amount required is small, which in turn reduces waste of liquid, which has the effect of increasing economic efficiency.
