Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method and apparatus for continuous dyeing of fabric, which causes shrinkage and texture in the fabric to be dyed during dyeing, and also has good dyeability. It is something.

Due to the shortage of natural fibers, synthetic fibers are currently being developed, and polyester fibers, which are effective as fabric fibers, have been mass-produced.

However, when compared with natural fibers, such polyester fibers lack dye adhesion, that is, dyeability, texture, etc.

Therefore, in the conventional method of imparting texture and shrinkage to the polyester fibers and then dyeing them, the current situation is that the texture and shrinkage are first performed individually, and then the dyeing process is carried out.

In this way, in conventional methods, the texture, shrinkage processing, and dyeing processing are performed using separate processing means, so for example, during the shrinkage processing, a large amount of heat energy, labor costs, and water are required. Resources, etc. are expended, and a large amount of labor costs, thermal energy, water resources, etc. are also expended during the dyeing process.

Therefore, the cumulative amount of thermal energy, labor costs, etc. during both processing is large, making it uneconomical.

The present invention has been made in view of the above,
The first purpose is to continuously perform shrinking and dyeing of fabric in the same steamer, which reduces the thermal energy and labor costs required by conventional methods by half, helping to conserve resources and reducing processing costs. It provides shrinkable and dyed fabrics.

A second object of the present invention is to perform dyeing with a high degree of dyeing by using a liquid jet dyeing method in combination without causing wrinkles in the fabric and maintaining a predetermined wrinkle.

Embodiments of the present invention for achieving the above objects will be described in detail below with reference to the drawings.

Reference numeral 1 denotes a steamer can body for treating fabric under high pressure and moist heat, and this steamer can body 1 is provided with a fabric inlet 2 and a fabric outlet 3; Each of the outlet ports 3 is provided with an inlet-side sealing mechanism 4 and an outlet-side sealing mechanism 5.

These sealing mechanisms are provided to allow the introduction and extraction of fabrics while maintaining high humidity and heat within the high-pressure steamer can body 1. It has a pair of seal rubber rolls 41, a liquid seal tank 42 and a throttle bar 43 provided on the inlet 2 side from the seal rubber rolls.

The other outlet-side sealing mechanism 5 includes a pair of seal rubber rolls 50 that are pressed against each other, and an annealing tank 52 provided on the outlet port 3 side of the seam rubber rolls.

Net conveyors 61 and 62 are vertically spaced apart inside the steamer can body 1, and the net conveyors 61 and 62 form a gap a, which serves as a fabric passage.

Nozzles 7 are disposed along the net conveyors 61 and 62 in a staggered manner to inject the dyeing solution into the gaps a.

Reference numeral 8 denotes a staining solution tray provided below the lower net conveyor 62, and the staining solution accumulated in the staining solution tray 8 is sprayed from the nozzle 7 by a pump (not shown). There is.

Reference numeral 9 denotes a drip-proof plate that prevents dew inside the steamer can 1 from dripping onto the fabric 10 being transferred within the steamer can.

Next, to describe its function, first, the inside of the steamer can 1 is maintained at a high humidity and heat of 120 to 155°C, the liquid sealing tank 42 is filled with a predetermined dye solution, and the slow cooling tank 52 is filled with a predetermined dyeing solution.
Fill the inside with cooling water.

Then, the fabric 10 is passed through the introduction side sealing mechanism 4, and the fabric 10 impregnated with the dyeing liquid is transferred to the net conveyor 6 in the steamer.
1 and 62.

The fabric transferred through this gap a is transferred to both the upper and lower net conveyors while the dyeing solution is re-penetrated into the fibers of the fabric, in order to receive the injection pressure of the dyeing solution sprayed from the nozzle 7 while the color development progresses. It is conveyed in a meandering manner as the net conveyor rotates.

Therefore, the fabric transferred by both the upper and lower net conveyors is subjected to the liquid pressure jetted from the nozzle 7, and the dyeing solution is further pressed into the fibers of the fabric and impregnated, and the fabric is repeatedly moved in a meandering manner between the upper and lower net conveyors. When the serpentine fabric is struck, and when the serpentine fabric rises and falls, the spraying force of the dyeing solution causes vibrations and an effective kneading force is exerted.

In this way, kneading and tapping forces are repeatedly applied to the fabric using the spraying force of a high-temperature dyeing solution (disperse dye) that is close to the temperature inside the steamer, effectively causing the fabric to shrink and texture. The staining progresses as the staining progresses.

Immediately before the fabric 10 is led out from the gap a, the fabric is dyed, shrunk and textured.

As described above, the present invention provides a fabric passageway in a gap formed by vertically disposing an endless net conveyor having liquid permeability, through which the fabric to be treated is fed into a high-pressure steamer in which high-temperature, high-pressure, moist heat is maintained. The dyeing solution is supplied into the interior and transferred as the endless net conveyor rotates, and furthermore, the dyeing solution is sprayed onto the transferred fabric in the fabric path from dyeing solution spray nozzles arranged vertically in a staggered manner along the fabric path. Since the high-temperature dyeing solution acts on the fabric, the high-temperature solution acts as a carrier, increasing the adhesion of the dye to the fabric, resulting in good dyeing and improving the wind of the fabric. When dyed, shrinkage occurs and a soft dyed fabric with firmness can be obtained.
