We hosted a great workshop on Sept. 19 called “Back to Workwear.” Tickets went quickly and we had a full house. I am humbled by how much interest there is in what we do, how we work and why we source specific materials.
We spoke about textiles first and, specifically, what’s so special about Japanese selvage denim.
To kick things off, we looked at the history of this cloth. The first denim cloth was made in the French city of Nîmes and was used to make sails for boats. It was a type of cloth called serge de Nîmes (the term serge refers to the twill or diagonal pattern that can still be seen up close on most pairs of jeans but, over time, the fabric would more commonly be shortened to de Nîmes). It could be more densely woven, and its structure provided some natural give, or elasticity.
During the gold rush to the Klondike, Levi Strauss, a German-American entrepreneur, popularized using denim fabric and dyed the warp yarns with what was, at the time, cheap natural, indigo dye. This is the era when American denim as we still know it today was born. It was during the second World War that Japanese culture was introduced to American denim via U.S. troops. At the time, Toyota (or Toyoda, as it was called then) was a loom manufacturer and it made improvements to the shuttle loom that was used to produce denim. Most notably, the Toyoda machine stopped automatically when its bobbin of yarn ran out.
The shuttle loom is key in selvage denim. It weaves much slower with yarn under much less tension than rapier looms, which are used in a lot of denim production today. I have posted a video below that shows the looms in operation at Kuroki, a denim mill in Japan’s Okayama prefecture, which I visited this past spring. In it, you can see a shuttle with a bobbin of yarn on it travelling back and forth. Its lower tension gives the fabric more elasticity across the body without the need to introduce synthetic Spandex, which stretches out over time and does not return to its original shape. This means a pair of jeans made from selvage denim will shape and mould to your body and come back to its original shape when washed. The other benefit is a beautiful, finished edge of the fabric, which is usually in a different colour and can be used as the finish on inside seams and in some subtle details in the garment. Incorporating a discrete selvage detail on a piece is appreciated by others who share a love for this historic cloth.
