Kapital – Century Denim
The prepared yarn is dipped in a mud pit. The chemical reaction between the tannin from the Yeddo hawthorn tree and the iron from the mud slowly transforms the yarn’s color into the color of the Earth.
After this long and careful process, the Sashiko yarn is ready to be sent back to the textile mill in Hiroshima, where Kapital Century Denims are woven by a customized loom.
The hanks of yarn spun in Hiroshima. These yarns are used for Sashiko stitches on Century Denim. Approximately 200g of yarns are used to finish one pair of Century Denim.
Locally grown Yeddo hawthorn tree.
Wood chips from the hawthorn tree are boiled. The remaining dye bath rests for a week to prepare for a deep brown dye.
The yarn is dyed first in this tannin-rich bath. A separate dye mixed with hydrated lime is added to adjust the concentration of acidity when dyeing the yarn. This process is repeated to make a base to mud-dyeing. The yarn is hank-dyed to the unique rich rusty-brown color.
Mordanting hanks of yarn in mud. The color changes to an earthy black.
This process is repeated about 30 times to achieve the color of Century Denim.
The dyed yarn is then rinsed in a stream. The use of the stream’s flow and the yarn’s rinsing by hand help check the yarn’s color.
