REAL AND GENUINE MANUFACTURING本物のものづくり

  • 綿 cotton
  • 色 colors
  • 織 weave

Although the actual weaving speed of these vintage looms is less than 1/5th the speed of modern shuttle-less looms, it is possible to weave high-count yarn properly with these older machines, giving the fabric an unevenness to the surface and a very special texture.The denim woven on these vintage looms is known as “selvage”.At Japan Blue, we define this fabric as “real denim”.

PRODUCTION PROCESS生産工程

  1. 綿
    Cotton

    • process01-1
    • process01-2

    Features high quality cotton with exceptional fiber length and whiteness from various countries. Taking advantage of the information and experience accumulated as a fabric manufacturer, we spin an original thread which maximizes the features of the cotton.

  2. 紡績
    Spinning

    • process02-1
    • process02-2

    The carefully selected cotton is spun into thread keeping in mind the changes in the texture that will occur over the following several years. Since the quality of cotton, which is a natural material, is not consistent from year to year, we make fine adjustments so that the quality will be as uniform as possible during the spinning stage.

  3. 染色
    Dyeing

    • process03-1
    • process03-2

    Indigo dye is so unstable in nature that is has been called "living." The proper equipment and experience is indispensable for reducing color blur and producing deep colors. We are actively working on the development of new colors such as "JAPAN BLUE DENIM" inspired by the color of natural indigo and "DARK BLUE INDIGO DENIM."

  4. 織布
    Fabric

    • process04-1
    • process04-2

    In order to take advantage of the characteristics of the raw material cotton and to make a durable fabric, a traditional shuttle loom that can weave thick threads slowly and firmly is essential. Our company operates nine G-Type Automatic Loom 'GL9's made by Toyota Industries Corporation, which is a loom that has disappeared as a result of improvements in the productivity of textile manufacturing, to manufacture "real denim".

  5. 裁断
    Cutting

    • process05-1
    • process05-2

    Kojima, the birthplace of Japanese jeans, is said to have about 200 jeans-related companies, large and small. Among them, there are specialists called "Cutting Studio" that cut denim fabric into 10 types of sewing components. In the past, denim cloth was cut with a single cutting chisel, but even today, where electric cutting has become the norm, the technology for cutting thick cloth continues to be passed down.

  6. 縫製
    Sewing

    • process06-1
    • process06-2

    The parts that have been cut at the cutting shop are sewn by hand. The parts that carry a lot of load when worn are sewn by trading out the normal needle and thread for a thicker thread to hold it together. The commitment of the meticulous sewing craftsman can be seen throughout the finished product. Making full use of 15 kinds of sewing machines including modern sewing machines and precious vintage sewing machines, it takes 30 different processes to manufacture one pair of jeans.

  7. 加工
    Manufacturing

    • process07-1
    • process07-2

    Jeans have a characteristic that other clothes don't have—they are sewn, washed once and then shrunk to the specified size. Kojima is also the birthplace of wash processing and the processing to get the "used" look that came from it. These processing techniques are being handed down from craftsmen to the next generation.
