Description

Jeans bleaching device using ozone gas

According to the present invention, when chemicals, water, and ozone gas are sprayed into the drum to decolorize jeans, some of water and ozone gas are mixed to generate ozone water, and some of the ozone gas reacts with water on the jeans to decolorize the jeans. It relates to a jeans bleaching device using eco-friendly ozone gas by reducing the amount of use, collecting ozone gas through a dust collector and discharging it as oxygen through decomposition and catalyst processes.

Jeans are usually very densely woven and are a generic term for trousers made from a fabric obtained by applying a blue (indigo) dye such as indigo blue.

Therefore, jeans are favorably used due to the practicality of being very tough and strong.

On the other hand, jeans, like other fashion clothes, are being produced in various forms while changing the shape and color according to the tastes and preferences of consumers.

In particular, since jeans are very tough and strong, but have a texture that is too stretchy at the beginning of wearing, individual consumers or manufacturers or merchants deliberately choose jeans that are first manufactured through sand blasting or stone washing treatment. They are often worn or sold.

On the other hand, the most commonly used method of bleaching jeans is to put the jeans on a tube, then inject air into the tube to inflate it, and then use an air spray gun to spray the bleaching solution on the jeans.

As described above, the method of spraying the bleaching solution (potassium permanganate solution) with an air spray gun is mainly used when bleaching only a part of the jeans because it cannot be sprayed evenly over the entire jeans.

In addition, in the process of spraying the decolorizing solution with an air spray gun, there is a problem in that the discoloration is different depending on the spray solution and the spray range, so the defect occurrence rate is high.

In addition, in the case of the first dyed jeans, the color is often very strong, so a bleaching agent such as sodium hypochlorite solution is used together in the process of processing in the drum to cause some discoloration, but there are many problems.

In the jeans bleaching method, the conventional conventional treatment for bleaching is putting chemical substances such as sodium hypochlorite or calcium hypochlorite in a large amount of water at 60 to 80 ° C. It was put in a drum and rotated for more than 30 minutes.

For example, if a certain type of tape is attached to jeans to produce a desired shape, the tape may be affected by water or other chemicals as well as the vortex in the water during rotation according to drum treatment, which may cause deviation from the original position. can

Moreover, the tape may frequently be pushed or separated from its original position while the adhesive component of the tape is softened due to the high temperature of the decolorization treatment.

Therefore, it is difficult to obtain the desired shape, and if the tape falls off the jeans in the middle of processing, the position where the tape was attached is also discolored, making it difficult to obtain a vivid color and shape.

The bleaching method requires a lot of water necessary for bleaching inside the drum having a water tank function, and when bleaching and bleaching is performed in water, the blue dye located in the bones of the jeans is also bleached and bleached to weaken the fabric as well as Depending on the bleaching solution or bleaching solution, the jeans fabric is brittle and torn.

In addition, in another embodiment, the pumice damage bleaching method uses volcanic stone to bleach jeans, and the pumice damage bleaching method uses volcanic stone, so a lot of sludge is generated and chemicals are also used because the jeans fabric is contaminated. There is a problem in that the work process is added due to the washing operation to remove it.

In order to solve the above problems, Patent Registration No. 10-2176807 "Jeans bleaching device" was applied for and registered.

However, the pre-registered jeans bleaching device has an excellent bleaching effect, but because it uses a lot of water, the cost of treating the water mixed with the bleaching agent is increased. There is a problem that the discoloration effect is lowered because it is not washed and the stained state is maintained, so that the discoloration is not uniformly.
