Material storage

We check the quality of the leather such as color and scratch arrived from the tannery amd conduct the inspection including the size one by one. And then we record the size, color, and quantity in the inventory notes before stock the leather flatly which is unusual in Japan. By this stock method, , the leather gets flat which keeps it in good condition even if the leather arrived roundly. Especially for heavy and thick leather it is important in quality maintenance and production effciency.

leather material

Iida Iwasaki has developed original leather in cooperation with domestic tannery. Especially in thick leather, JTR (color oil leather) which is developed with efforts with Tochigi Leather dominated the casual belt share. Such development and distribution which cannot be done by other companies is the unique characteristic of Iida Iwasaki. We will continue to propose new materials developed with tanneries including overseas.

Craftmen changes the amount of gule and the way to polish by judging the leather condition and difference of tanning. This polishing process determines the quality of side coating process.

Empty drum・Water soaked drum

We put the leather or leather cut into strip shape into the drum which is used for tanning and dyeing by rotating, and the fiber of leather get loosen and softner. In addition, we also use the drum to make the wrinkle or twisted so that the leather look like damaged. In this process, sometimes the leather is soaked in water or somethimes without water before being put into empty drum. By doing this we will change the expression when finish this process. Since it is imporatnt how long it will take times to become damaged properly, we bring it closer to desired finish with our extensive know-how and experiment using samples.

Buffing process

By using special wax, its common name, “burning wax” and buffing machine (rotating brush), used leather can be expressed. This kind of processed belt is popular because this process can be used for all kinds of tanned leather, such as tannic tanned, chrome tanned or pigment paint leather. Combined with the process of using rotating drum, more advanced aging process can be realized.

Dyeing

This is the process of dyeing by hand. Unlike the spray color blowing, it is difficultto paint evenly. But the shades of color and the fine expressive power unique to hand hyed are attractive. Basically it is often applied using a sponge, but the possibility of various process by changing the tool is one of features. It is a process that you can feel the manual warmth.

Coloring with hand spray

We can color leather using dyes and pigments. Thanks to this, small lot order can be acceptable even if the order require multicolor. In addition, it is possible to color not only the leather before cut but also after cut, so it is also possible to partially color or gradation.
