Description

Continuous printing method of fabric

1 is a cross-sectional view showing an embodiment of a device used for carrying out the dyeing of the present invention.

2 is a graph showing the relationship between dyeing time and dyeing degree.

The present invention relates to a continuous printing method of woven fabrics which makes it possible to increase the dyeing property of the printing dyes when the dyeing material having a dye applied to the surface is fed into the high pressure steamer for dyeing. At present, as a means for fixing (dying) a dye of a fabric coated with a dye in a predetermined pattern, it has been proposed to continuously supply the final dyeing fabric into a high-pressure steamer in which high-pressure wet heat is maintained and to fix the dye under the wet heat. .

However, in the related art, although high humidity heat has been studied to be retained in a high-pressure steamer, the steam tube is likely to be in a dry heat state, and it is difficult to retain sufficient wet heat in the steamer tube, and in particular, due to the lack of humidity for fixing dyes. It takes a relatively long time (for example 2-3 minutes) to complete the fixing of the dye, there was a problem that it is difficult to quickly dye and high-quality dyeing. It is also contemplated to contain a large amount of moisture in the printing fabric to be supplied into the high pressure steam to compensate for the lack of the moist heat during the wet heat treatment in the high pressure steam. However, in this case, the printing fabric containing humidity is the inlet seal of the high pressure steam. There is a problem that a part of the printing dye is transferred to the surface of the seal roll while being subjected to the nip pressure of the roll, and the seal roll is fouled, or the liquid is squeezed by the nip pressure. In addition, when the fabric containing the humidity of room temperature is supplied into the high pressure steamer, it takes some time for the room temperature fabric to be heated up until it is about the same as the temperature in the high pressure steamer. There was also.

The present invention has been studied to eliminate such drawbacks, and its purpose is to increase the moisture content of the fabric by applying a high-temperature liquid to the printing fabric supplied in the high pressure steamer to speed up the dyeing of the printing fabric supplied in the high pressure steamer. Dyeing dog is to realize good printing dyeing.

These sealing mechanisms 5 and 6 are provided so as to allow the introduction and extraction of the fabric while maintaining the high humidity in the steamer tube 1.

The introduction side seal mechanism 5 has a pair of seal rubber rolls 5 ₁ pressed against each other, a decompression chamber 5 ₂ provided on the inlet 2 side from these seal rubber rolls 5 ₁ , and this pressure reduction A fabric passage 5 ₃ extending from the seal 5 ₂ toward the inlet ₂ , a gas supply pipe 5 ₄ for supplying pressure gas into the pressure reduction chamber 5 ₂ , and this gas supply pipe 5 _4. ) from the pressure chamber ₍₅₂₎ is brought into contact with the first seal rubber roll ₍₅₁₎ for the pressure gas which flows into the inflow into the pressure chamber ₍₅₂₎ after cooling the seal rubber roll (5 ₁₎ at a temperature of the gas It has a guide wall (5 ₅ ) to make it. Similarly to the introduction side work mechanism, the lead-out seal mechanism 6 also has a pair of seal rubber rolls 6 ₁ which are press-contacted with each other and a slow cooling liquid tank 6 ₂ formed in a substantially J-shape. ), A liquid supply pipe (6 ₃ ) for supplying the slow cooling liquid, which also serves as a cleaning in the slow cooling liquid tank, from the outside of the steamer, and a liquid introduced into the slow cooling liquid tank (6 ₂ ) from the liquid supply pipe (6 ₃ ). It has a guide wall 6 ₄ for contacting 6 ₁ and allowing the seal rubber roll 6 ₁ to cool at the liquid temperature, and then flowing it into the slow cooling liquid tank 6 ₂ .

(7) includes a tension adjusting roll (8) among the fabric guide rolls installed in the steamer tube (1) in the upper and lower zigzag.

(9) is a heating liquid spray nozzle for attaching and impregnating a heating liquid, for example, a hot liquid on one side, for example, a back side, of a fabric 10 of a straight button which is supplied into the steamer tube, and instead of the spray nozzle, the liquid containing An appropriate amount of liquid may be applied to the fabric as a roll.

11 is a storage tank which receives a heating liquid. Reference numeral 12 denotes a liquid tank in which the guide roll 7 disposed below the outlet of the steamer tube 1 is immersed, and a cleaning liquid is filled in the liquid tank 12. (13) is a squeeze rod which has a plurality of doors arranged so as to squeeze the liquid every time the fabric 10 comes out of the liquid tank 12.

Denoted at 14 is a medium blow pipe for maintaining the steam heat in the steamer tube 1, and 15 is a plate which prevents condensation droplets in the steamer from falling onto the fabric 10 transported in the steamer tube.

Next, the operation thereof will be described. In the steam pipe 1, steam is blown out by the steam blowing pipe 14, and the gas supply pipe 5 ₄ is supplied with a pressure gas into the pressure reducing chamber, and the liquid supply pipe 6 ₃ ), cold water is supplied into the slow cooling tank 6 ₂ to cause the sealing mechanisms 5 and 6 to be sealed, and the steamer tube 1 is maintained at a high pressure and heat state of l00 ° C to 160 ° C. . On the back side of the fabric 10 immediately after the dye is applied to the surface of the fabric by the printing means from the outside and the dried printing fabric 10 is supplied into the steamer tube 1 through the inlet-side sealing mechanism 5, A heated heating liquid is mounted from the spray nozzle (9), and then transported in the guide rollers (7) and (8), which is heated to approximately the steamer internal temperature, during which the dye and heated liquid are impregnated with the fabric ( 10) is steamed.

The gist of the present invention is to impregnate the fabric with sufficient moisture on the back side of the fabric 10 immediately after supplying the fabric coated with the dye to the surface of the fabric 10 into the tube of the high pressure steamer. That is, immediately after the dye 10 is applied and the fabric 10 in the dry state is supplied into the steamer body 1, a high temperature in the steamer body is acted upon by applying a heating solution to the back surface of the fabric, so that the fabric is hot By the high humidity and high humidity, the applied dye penetrates to the deep portion of the fabric, and there is an effect that the deep dyeing is realized.

In this way, the fabric supplied in the steamer tube is brought to a high temperature and high humidity state, and the dye applied to the fabric is rapidly dyed onto the fabric, and the fabric is transferred from the guide roller 7 in the high pressure steamer (for example, around 5 seconds). ) Is completely dyed and introduced into the liquid bath 12. Each time the fabric supplied in the liquid tank 12 is drawn out of the liquid tank 12, the liquid is squeezed by the squeeze rod 13, so that the liquid is rapidly replaced, and the fabric is swelled by the high temperature in the steamer. In addition, it becomes an effective prewash. The fabric prewashed in the liquid tank 12 is washed at the same time as the slow cooling in the slow cooling liquid tank 6 ₂ to be taken out of the steamer tube and transferred to the next step.

As described above, in the present invention, immediately after supplying the fabric to which the dye is already applied by the printing means into the steamer tube maintained under high pressure and humidity heat, the high-temperature moisture heated at about the same as the temperature inside the steamer tube on the unprinted side of the fabric is applied. It is sprayed or applied in a range that does not flow, and the applied dye rapidly penetrates deep into the core of the fabric by the high heat moisture and high humidity heat in the steamer tube. In addition, there is an effect of obtaining excellent dyeing dog by becoming a near-perfect deep dyeing without falling off of the dye.

In addition, since the liquid temperature of the heated solution sprayed in the steamer can be made constant at all times corresponding to the constant humidity in the steamer tube, there is also an effect that the uniform and stable dyeing treatment can be continuously performed continuously.

In order to clarify the effects of the present invention, the dyeing effect between the conventional dyeing method without water and the dyeing method of the present field with hot water is shown in FIG.

As is apparent from this graph, the present invention shows that the fabric fed into the steamer is completely dyed immediately. In addition, the test fabric used for the test was a 100% polyester processed yarn, the twill fabric, the dye used was Kayalon polyester black G-SF paste 7% (dispersant), and the moist heat temperature was 155 ° C.

In addition, although the test fabric was performed in polyester in the said Example, the dye-wetting heat temperature and dye which are required for various fiber fabrics and these fibers are as follows.
