Description

[Detailed Description of the Invention] The present invention relates to an apparatus in which a fabric subjected to thermal treatment is set in a spread state in a high-pressure steamer and led out of the steamer.

It has been proposed in the past that knitted fabrics and woven fabrics be subjected to desizing, scouring, bleaching, dyeing, etc. under high humidity and heat, and the present inventor has also proposed a more effective method. There are also many proposals regarding processing methods and devices that can carry out such processing in a short period of time.

In general, when fabrics such as wool are treated under high humidity and heat of about 130°C, the fabric shrinks due to the high heat, and when clothes are made from the fabric, it tends to lose its shape. was there.

The present invention has been developed in view of the above, and is designed to spread the fabric that has been shrunk in the high-pressure steamer to a predetermined width before being taken out from the high-pressure steamer, and then set the cloth so that the cloth can be taken out of the steamer. .

Specifically, the present invention includes a decompression chamber sealed at a fabric outlet of a high-pressure steamer casing by a sealing mechanism having a sealing roll capable of sealing the fabric outlet but allowing fabric to pass through. A cooling chamber is arranged adjacent to the decompression chamber and the cooling chamber in this order in the direction in which the fabric is taken out, and a forced spreading roll is provided in the decompression chamber.

Therefore, according to the present invention, by cooling the heat-treated fabric at the same time as spreading it just before it is taken out from the high-pressure steamer, it is possible to effectively widen the fabric and achieve the desired purpose. .

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

Reference numeral 1 denotes a high-pressure steamer housing, and 2 denotes a fabric outlet provided in the housing 1.

A seal rubber roll 4 having a fabric insertion passage 3 for transferring the fabric in a vertical meandering manner is fixed to the fabric outlet 2, and an opening 3 on the case 1 side of the fabric insertion passage 3 formed by this seal block ' is a decompression chamber 5 extending inside the housing 1.
Further, an internal sealing mechanism having a pair of gap rolls 6 is provided at the tip opening of the decompression chamber 5.

Further, the outlet side opening 3'' of the seal block 4 is provided with an external sealing mechanism having a pair of seal rubber rolls 7 that are pressed against each other, and a fabric passage between the external sealing mechanism and the internal sealing mechanism is provided. is designed to be depressurized.

The inside of the fabric insertion passage 3 of the seal block 4 is approximately divided into two,
Cooling water 8 is sequentially supplied and circulated in the direction of the external seal mechanism.

9 is its cold water supply pipe, and 10 is its drain pipe.

The other part of the fabric insertion passage 3 divided into two is configured to provide reduced pressure air, and a width expanding roll 11 is rotatably supported in this reduced pressure air chamber.

Various types of this spreading roll have been proposed by the inventor of the present invention, and some have been publicly announced.For example, as shown in Figure 2A, there are spiral protrusions extending from the center of the roll in opposite directions to both ends. 11', or one in which sliding pieces 11'' are symmetrically provided on the outer circumferential surface of the roll so as to slide toward both ends of the roll, as shown in the opening of FIG.

As described above, in the present invention, while the fabric, especially the wool, that has been heat-treated in the high-pressure steamer is led out of the steamer housing through the reduced pressure fabric insertion passage and the cooling water 8, that is, the fabric is cooled. Immediately before it is immersed in water 8, it is guided and transferred by the spreading roll 11 and spread, and then it is immediately immersed in cooling water and cooled, so that the spread state is like a cooling cellar!・Can be led out of the steamer as it is.

As described above, in the present invention, the wool fabric, which has been shrinked by thermal treatment in a high-pressure steamer, is forcibly spread just before it is taken out from the steamer and at the point where it has flexibility, and then it is immersed in cooling water. By doing so, the spread state is cooled and the desired spread is effectively achieved, and this is particularly effective during high-humidity heat treatment of wool fabrics.
