Charcoal Dyeing

Sumizome is a dyeing technique that uses powdered bamboo or wood charcoal to permeate yarn and fabric. It is characterised by a unique silvery look that appears in the gradation from grey to black. The charcoal itself does not deteriorate when exposed to ultraviolet rays, so the colour changes little even after dyeing and exposure to sunlight, and the colour remains stable for a long time. At MITTAN, we dye our products in a dyeing factory in Okayama using a large washing machine-like dyeing machine called a washer.
