JPS5927425B2 - Coloring steamer for both reactive dyes and dispersible dyes - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a steamer structure that can serve as both a coloring steamer using reactive dyes and a coloring steamer using dispersed dyes.

As is well known, cotton fibers and polyester fibers are often used as fibers for knitting or weaving fabrics.
Reactive dyes are effective for dyeing cotton fibers, and disperse dyes are effective for dyeing polyester fibers. Both sex dyes are used.

Since dry heat is desirable for dyeing reactive dyes, and moist heat is desirable for dispersive dyes, dry heat dyeing equipment is used when reactive dyes are used; When using synthetic dyes, a wet heat dyeing device is used.

Conventional dry heat dyeing equipment and wet heat dyeing equipment are side structures with respective features, and dyeing companies currently use both types of equipment.

However, recently there are many fabrics made of blended, interwoven, interwoven, etc. cotton fibers and polyester fibers, so when dyeing such fabrics, it is necessary to dye the fabrics by using the dry heat dyeing machine and the moist heat dyeing machine. Since two steps have to be carried out, there is a problem in that the dyeing process is laborious and expensive.

Further, since both the dry heat dyeing device and the wet heat dyeing device are complicated devices, there is a problem in that installing both devices requires a large amount of equipment cost and installation space.

The present invention has been made in view of the above, and aims to develop a dyeing apparatus that can serve as both a dry heat dyeing apparatus and a wet heat dyeing apparatus, thereby solving the problems of the conventional dyeing apparatus.

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

Reference numeral 1 denotes a steamer can body for dyeing a fabric 2 to be dyed under high-pressure wet heat or high-pressure dry heat, and this steamer can body 1 has a fabric inlet for continuously inserting the fabric 2. 3 and a fabric outlet 4 are provided, and the fabric inlet 3 and fabric outlet 4 are provided with high pressure (
An inlet-side seal mechanism 5 and an outlet-side seal mechanism 6 are provided to maintain the pressure at normal pressure or higher.

These sealing mechanisms are provided to allow the introduction and extraction of fabrics while maintaining high humidity and heat inside the high-pressure steamer can body 1. It has a pair of sealing rubber rolls 5□, a liquid seal/staining liquid tank 5□ provided on the inlet 3 side from the sealing rubber rolls, and a squeeze bar 53.

Further, the other outlet-side sealing mechanism 6 has a pair of seal rubber rolls 61 pressed against each other, and the outlet port jHjt! is connected to the seal rubber roll. It has a slow cooling tank 62 provided with 1K.

Reference numeral 7 denotes a group of guide rolls for transporting the fabric 2 within the steamer can body 1. At the inner bottom of the steamer can body 1, which is below the guide roll group 7, there is a water tank 8;
A water supply pipe 9 for appropriately supplying water into the tank, and a superheated steam injection pipe 10 for converting the water supplied by the water supply pipe 9 into steam are provided.

Reference numeral 11 denotes a superheated steam injection pipe disposed above the inner cut of the steamer can 1 above the guide roll group 7, and a superheated steam injection pipe 11 injects superheated steam into the steamer can 1 near the superheated steam injection pipe 11. A cover 12 and a baffle plate 13 are provided to uniformly act on the entire area of the inside.

The superheated steam injected from the superheated steam injection pipes 10 and 11 is dry heat air in a superheated state.

14 is a drip-proof plate. The above is the structure of this example,
Next, to describe its function, when dyeing is performed using a dispersible dye in this steamer can 1, water is supplied into the water tank 8 of the steamer can 1, and then from the superheated steam injection pipe 10. Superheated steam is sent in to turn the water in the water tank 8 into steam (vaporization), increasing the humidity in the steamer can 1, and using this high humidity, the fabric 2 is dyed with the disperse dye.

During dyeing using reactive dyes, water in the water tank 8 is removed to stop the generation of steam, and superheated air at a temperature higher than the saturated steam pressure, that is, dry heat, is injected from the superheated steam injection pipes 10 and 11. Air is blown out to bring the inside of the steamer can body 1 into a dry heat state, and the reactive dye is dyed onto the fabric 2 by this dry heat.

As described above, according to the present invention, the interior of the steamer can 1 can be selectively placed in either a wet heat state or a dry heat state, so that both dyeing with the disperse dye and the reactive dye are the same. Since it is carried out in a steamer can, the drawbacks of the conventional method can be eliminated.

Further, according to the present invention, the superheated steam injection pipes 10 and 11 are arranged at the lower and upper parts of the steamer can body 1, and the baffle plate 13 etc. create a uniform dry heat atmosphere throughout the steamer can body. Because it is possible to dye the fabric with reactive dyes evenly and uniformly.

Although the above embodiment uses a steamer can 1 that is maintained at high pressure, the steamer can 1 is not limited to this, and the steamer can 1 may be a steamer can that maintains normal pressure without a sealing mechanism. good.
