Description

jeans bleaching device

In order to bleach jeans in large quantities, the present invention inserts a large amount of jeans into a drum and then sprays a bleaching solution using potassium permanganate mixed with water into the drum while rotating the drum in the forward and reverse directions to make the bones of jeans fall It relates to a jeans bleaching device that prevents the discoloration solution from penetrating and damages the fabric, and is sprayed evenly on the surface of the jeans to discolor the jeans uniformly.

Jeans are a generic name for trousers made from a fabric obtained by applying a blue (indigo) dye such as indigo blue to a very densely woven twill weave.

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 used method of bleaching jeans is to put the jeans on a tube, inject air into the tube to inflate it, and then use an air spray gun to spray the bleaching solution (potassium permanganate solution) on the jeans. are using

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 decolorization solution with an air spray gun, the discoloration varies depending on the spray solution and the spray range, so there is a problem that 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 drum treatment process to partially bleach the color, but there are many problems.

In the jeans bleaching method, the conventional conventional treatment for bleaching is putting a chemical substance 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 is not only affected by water or other chemicals, but also is affected by the vortex in the water during rotation according to the drum treatment, which may cause deviation from the original position. can

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

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 required 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 bone 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 there is a lot of sludge 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.
