Further, as the reformed object according to the present invention, a product currently on the market as a final product may be applied, or an intermediate product at the manufacturing stage may be applied. In addition, the raw material before the start of production may be applied.

<2. Aging process>
The aging step according to the present invention is described in <1. The reformed object described in> Modified object> is stored in water. Examples of the storage environment include the sea, rivers, lakes, and artificial pools. Among them, it is particularly preferable to store it in the sea.

By setting the storage environment in the sea, the reformed object is exposed to various stresses such as tidal current, sound, vibration, water temperature, water pressure, pH, salinity, and contact with aquatic organisms (fish, shellfish, etc.). As a result, it is possible to give the modified object a unique texture that cannot be obtained by ordinary processing techniques.
In addition, by aging in the sea, it is possible to obtain a branding effect that cannot be achieved by a normal product, and it is possible to add value to the product.

Here, the storage is preferably at a depth of 5 to 500 m, more preferably 10 to 300 m, more preferably 10 to 100 m, still more preferably 20 to 50 m from the water surface.

The storage period is preferably 1 day to 1 year, more preferably 2 days to 9 months, more preferably 15 days to 6 months, more preferably 1 to 6 months, still more preferably 2 to 6 months. Is preferable.

The reformed object to be stored is preferably stored in a storage state from the viewpoint of theft and loss prevention, but is not limited to this form. For example, the reformed object connected by a rope or the like may be stored in the sea as it is without using a storage. In any form, the object to be modified can be stored after being packed with a water-soluble packing material.

It is also preferable that a plurality of objects to be modified are bound together or covered with an emblem or the like so that a part of the dough is not directly exposed to the water stream and is stored in a covered state. As a result, the texture of processing can be changed between the portion of the fabric stored in a covered state and the other portion.

Further, the storage used in the aging step is not particularly limited as long as it is water-permeable and can hold the reformed object in water. For example, a water-permeable underwater storage having a lid or a door that can be opened and closed in the direction of the water surface and / or in the direction orthogonal to the water surface direction can be exemplified. When installing the storage on the bottom of the water, it is preferable to fix it with an anchor. Further, from the viewpoint of theft prevention and the like, it is preferable to provide a key on the lid or the door.

In the aging step according to the present invention, damage processing by aquatic organisms can be performed by storage in water (see FIGS. 3 to 5). The degree of damage can be adjusted by changing the storage period.

According to the present invention, the degree, position, and content of damage differ depending on the modified material produced, and it is possible to produce a highly original product, which can motivate consumers to purchase. ..

On the contrary, it is possible to keep the quality constant, such as the degree of damage to the produced modified material or the degree of discoloration after the cleaning process. In this case, the reformed object is stored in water in a state of being stored in a storage bag such as a fine net. This makes it possible to prevent the damage processing by aquatic organisms. Further, since the reformed object is stored in the same underwater environment, the degree of discoloration after the washing step can be made the same.

When performing the aging process using an artificial pool, it is possible to obtain the same effect as when storing in the sea by creating a storage environment that imitates the natural environment and growing aquatic organisms in it. it can.

<3. Cleaning process>
The present invention is characterized by having a washing step of washing the reformed object after the aging step with water. The cleaning step refers to rinsing the reformed object landed through the aging step with running water and / or immersing it in a container containing water for cleaning. At that time, you may massage and wash by hand.

The number of cleaning steps can be appropriately changed according to the desired degree of discoloration, but from the viewpoint of obtaining a sufficient discoloration effect compared to the material before modification and achieving differentiation, a plurality of cleaning steps are performed. It is preferable to repeat this process. More specifically, the cleaning step is preferably performed once or more, more preferably twice or more, and further preferably three times or more.

The time provided for the washing step is not particularly limited, and can be appropriately changed according to the desired degree of discoloration. As a guide, it is preferable to wash for 1 to 60 minutes, more preferably 5 to 30 minutes, and further preferably 5 to 15 minutes.
Further, the degree of discoloration can be changed by properly using cold water or hot water.

The degree of discoloration can also be changed depending on the state of the object to be modified during the cleaning step after the aging step. After the aging process, the wet reformed object is dried by a conventional method such as natural drying such as sun-drying or shade-drying or mechanical drying with a dryer, and the washing process is performed after the drying to determine the degree of discoloration. Can be reduced.

From the viewpoint of hygiene, it is preferable to wash the reformed object after the washing step with a clothes detergent or the like. At that time, in order to prevent unintended discoloration and color transfer to other clothes, it is preferable to add a color stopper according to the type of dye or the like and the dyeing method in the object to be modified for washing.
From the viewpoint of consideration for the environment, it is preferable to treat the dye that has flowed out of the object to be reformed during the cleaning step after performing appropriate wastewater treatment by a conventional method.

The modified material produced through such a process can be further processed by a known processing technique and then put into a final product.

A new denim shirt was stored in a storage and submerged in the seabed at a depth of about 21 meters. 56 days after the start of storage, the denim shirt in the storage was withdrawn to land. At that time, no outflow of dye from the denim fabric was confirmed.

A wet denim shirt within 1 hour after landing was placed in a commercially available container, about 20 L of running water was collected therein, rinsed, and left for about 10 minutes. The washing step was repeated 3 times. At this time, in order to compare the change in color fading depending on the number of cleaning steps, the discolored water generated during the washing step was collected each time. The dye that flowed out of the denim shirt was treated as wastewater by a method specified by the local government.

Finally, the denim shirt after the washing step was put into a commercially available washing machine, washed with a laundry detergent by a usual method, and then dried. Then, for comparison, a photograph was taken of the denim shirt manufactured through this process and the product in the state at the time of purchase, which was prepared separately.

FIG. 1 compares a denim shirt manufactured through an aging step in the sea and three washing steps (Fig. 1, left), and the same product in the state at the time of purchase (Fig. 1, right), which has not undergone these steps. The photograph is shown. Further, FIG. 2 shows a change in color fading depending on the number of times the cleaning process is performed. Then, FIGS. 3 to 5 show a state in which the denim shirt manufactured through the aging process has been damaged by aquatic organisms.

As shown in FIG. 1, the denim shirt manufactured through each process according to the present invention (Fig. 1, left) has a remarkable discoloration of dye as compared with the same product (Fig. 1, right) which has not undergone the process. Was done. Further, as shown in FIG. 2, it can be seen that the degree of discoloration of the dye changes as the number of washings increases. In FIG. 2, the first cleaning (left in FIG. 2) had the smallest degree of discoloration, and the second cleaning (center in FIG. 2) had the largest degree of discoloration. The degree of discoloration in the third cleaning (right in FIG. 2) was about halfway between the first and second cleaning.

From these results, according to the present invention, the aging of the object to be modified is promoted, and a remarkable discoloration effect that cannot be obtained by ordinary washing is exhibited in spite of only three washings. Was confirmed.

In addition, as shown in FIGS. 3 to 5, by storing the denim shirt in the sea for about 2 months and aging it, holes created by the aquatic organisms biting the denim shirt and the aquatic organisms themselves adhere to the denim shirt. It was confirmed that damage processing such as denim was applied.

From the above results, it was found that the modified material can be produced by going through each step of the present invention.

The present invention can be applied as a material modification technique.
