Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dyeing apparatus for textile products, which is especially advantageous for spot dyeing or light and shade dyeing of textile products such as strings, threads, tapes, tows, etc.

For example, it is well known that the conventional means for dyeing fabrics etc. in spots involves applying a desired dyeing solution to the surface of the fabric to be dyed in spots and dyeing it using a predetermined dyeing method.

However, when performing spot dyeing of textile products in the form of strings, threads, or tapes using this type of conventional known means, the thermal efficiency of the dyeing solution during dyeing or dyeing may be extremely poor.

In other words, when applying a dyeing liquid to textile products such as strings, threads, tapes, etc., if the dyeing liquid is sprayed, for example, to create shading, most of the dyeing liquid will be removed, especially in the case of yarn. However, if the textile product is immersed in a dyeing solution tank and passes through it in order to increase the application rate, it would be possible to achieve the objective. This makes it impossible to dye in different shades.

Furthermore, even if textile products such as yarn coated with a dyeing liquid are passed through a wet heat dyeing device such as a high-pressure steamer, it is not productive to let the textile products such as yarn pass through in a straightly stretched state. It was hot.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide an apparatus that enables effective light and shade dyeing to be carried out continuously and in mass production.

That is, to describe the present invention specifically, thread-like, string-like,
A textile product shaping machine that curls a textile product such as a tape or tow; a pair of upper and lower net conveyors for vertically pinching and transporting the textile product curled by the textile product shaping machine;
A dyeing solution applying means for spraying the dyeing solution onto the textile products transferred by the upper and lower net conveyors, and a high-pressure, moist heat method that holds the textile products to which the dyeing solution has been applied is held between the net conveyors. A continuous dyeing apparatus for textile products is provided, which comprises a high-pressure steamer for continuous dyeing of textile products.

According to this dyeing device, the dyeing liquid is sprayed onto the fiber products in a state where they are overlapped in a curled manner, thereby making it possible to perform mottled dyeing or dark and light dyeing, and also to improve the productivity of dyeing.

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

1 is a lower endless conveyor, 2 is an upper endless conveyor, and the upper and lower net conveyors have portions 1' and 2' which are moved close to each other in parallel.

3 is a curling device for curling the yarn 4 and sequentially placing it on the net conveyor 1. Immediately after the curled yarn 4 is placed on the net conveyor 1, it is transferred to the upper net conveyor 2. Therefore, in the sandwiched state, it can move from the left to the right in the figure as both conveyors move.

5 is a dyeing solution spray nozzle for spraying a predetermined dyeing solution toward the curled yarn 4 held by the upper and lower net conveyors, and 6 is an intermediate device installed next to the dyeing solution spraying nozzle 5. The dryer 7 is a high-pressure steamer through which the yarn is passed while being held by a net conveyor, and the inside of the high-pressure steamer 7 maintains high-pressure, moist heat of, for example, about 160°C. The sealing devices 7a and 7b provided at the inlet and outlet of the high-pressure steamer are configured to allow the thread 4 and the net conveyor to pass through, but to retain the high-pressure moist heat inside the steamer. The sealing devices 7a and 7b have various structures developed by the present inventor, and many of them are known, and since they are not the subject of the present invention, a description of the sealing devices 7a and 7b will be omitted. Reference numeral 8 is a washing chamber for washing the yarn discharged from the high-pressure steamer 7, and 9 and 10 are conveyor washing chambers for washing the net conveyor.

The structure of this embodiment has been described above, and its operation will be described next.

First, the yarn 4 is formed into a curled layer (see FIG. 2) by the curling device 3, and is sequentially dropped onto the lower net conveyor 1. This curled superimposed yarn is soon pressed and transferred by the upper net conveyor 2, and first absorbs the liquid jetted from the dyeing liquid jetting nozzle 5. Since the curled superimposed yarn has an overlapping part of the yarn and an overlapping part with the net conveyor, there are some parts where the dyeing solution is not attached, and the dyeing solution-impregnated part becomes uneven or light and dark, resulting in uneven dyeing. is obtained.

This yarn is supplied into the high-pressure steamer 7 through the sealing device 7a in a half-dried state by the intermediate dryer 6. Since the dye impregnated into the thread when passing through this sealing device 7a is in a half-dry state, it is relatively unlikely that the dye will be transferred to the sealing roll or the net conveyor even if it is pressed against the sealing roll 7a' of the sealing device. few. In this way, the dye of the yarn supplied into the high-pressure steamer and subjected to high-pressure moist heat is fixed to the yarn for 1 to 2 minutes, and then led out of the steamer through the exit side sealing device 7b, and then washed in the cleaning room. After being dried, the cheese is rolled up into cheese 11 after passing through a drying means (not shown) for an appropriate period of time.

In the above embodiments, the workpiece is described as a thread, but it is not limited to this; string-like objects, tape-like objects, tows, etc. can be processed in the same way, and furthermore, a single thread, a string, a tape, etc. The structure is not limited to the shape, but a structure may be adopted in which a plurality of strips are passed through the high-pressure steamer at the same time, or a pair of upper and lower net conveyors are passed through the high-pressure steamer to enable simultaneous processing of multiple rows.

As described above, according to the present invention, it is possible to dye unevenly by forming long workpieces such as threads into a curl-like superimposed state and spraying the dyeing solution, and then treating this with high-pressure moist heat in a high-pressure steamer. This has the effect of staining spots in a short time. That is, according to the present invention,
Because the fiber products are layered in a curled manner,
Compared to folded textile products, there are significantly more overlapped areas, and effective mottled dyeing can be expected.

Furthermore, since long workpieces such as threads are in a curled state in the steamer, they stay in the high-pressure steamer for a long time and can be mass-produced.
